    Turnover of derivatives has grown more rapidly in emerging markets than in developed countries. Foreign exchange derivatives are the most commonly traded of all risk categories, with increasingly frequent turnover in emerging market currencies and a growing share of cross-border transactions. As the global reach of the financial centres in emerging Asia has expanded, the offshore trading of many emerging market currency derivatives has risen as well. Growth in derivatives turnover is positive...

    Full Text Available Globalization of financial markets led to the enormous growth of volume and diversification of financial transactions. Financial derivatives were the basic elements of this growth. Derivatives play a useful and important role in hedging and risk management, but they also pose several dangers to the stability of financial markets and thereby the overall economy. Derivatives are used to hedge and speculate the risk associated with commerce and finance.

    Full Text Available The aim of this study was to evaluate excretion of purine derivatives and microbial–N supply in lactating Etawah crossbred goats fed with fermented soybean waste. Sixteen first lactating goats were randomly allotted into four dietary treatment groups that received 50% king grass plus R1: 50% concentrate, R2: 25% concentrate and 25% fresh tempe waste, R3: 25% concentrate and 25% fermented tempe waste, and R4: 25% concentrate and 25% gelatinizing of liquid tempe waste. Fermented tempe waste was made by fermentation of tempe waste (seed content of soybean using Aspergillus niger, while for the gellatinizing of liquid tempe waste was made by gelatinized with maize flour. Protein balance studies were conducted during two week trial and at the end of the research. Urinary protein and purine derivatives were collected for analysis. Microbial–N supply was calculated from purine derivatives excretion. Results showed that nitrogen consumptions were significantly different between R4 and three other treatments and apparent digestible nitrogen in R3 were higher than that of R4 (P<0.05. The nitrogen retention in R1 and R3 were higher than that of R2 and R4. Urinary purine derivatives in this study showed that allantoin, xanthine and hypoxanthine in R3 were higher than that of R4, while R1 and R2 were the same and the highest uric acid excretion and total purine derivatives were observed in R3. Microbial–N supply were significantly different between all treatments where R3 was the highest. This research concluded that fermented soybean waste had the highest total purine derivatives excretion and microbial–N supply to the lactating Etawah crossbred goats.

    Full Text Available The objective of the study was to determine the effects of feeding Lactobacillus species (Lactobacillus sp. and inulin derived from dahlia tuber powder on antioxidant activity, calcium mass, and protein mass of crossbred kampong chicken meat. A total of  168 birds of 21 days old crossbred kampong chickens were randomly allocated into 6 treatments with four replications per treatment. The present experiment was assigned in  a completely randomized design with 2 x 3 factorial scheme. The first factor was levels of dahlia tuber powder, namely 0.8% (A1 and 1.2% (A2, and the second factor was levels of Lactobacillus sp., namely none (B0, 1.2 mL (108 cfu/mL/B1 and 2.4 mL (108 cfu/mL/B2. The parameters measured were antioxidant activity, meat calcium and protein mass. Data were subjected to analysis of variance and followed by Duncan multiple range test (P<0.05 when the treatment indicated significant effect. The supplementation of dahlia tuber powder and Lactobacillus sp. significantly (P<0.05 increased antioxidant activity and protein mass of meat. However, calcium mass of meat was not significantly affected by treatments. In conclusion, feeding dahlia tuber powder at the level of 1.2% combined with Lactobacillus sp. at 1.2 mL (108 cfu/mL, can be categorized as the best combination based on the increase in antioxidant activity and meat protein mass.

    Ojeda, A.; Parra, O.

    1999-01-01

    Four experiments were carried out to establish a response model between urinary excretion of purine derivatives (PD) and microbial production in Bos indicus x Bos taurus cross-bred cattle: LZ, MZ and HZ (3/8, 1/2 and 5/8 Bos indicus, respectively). The fasting PD excretion was considered as endogenous excretion and amounted to 268 (± 85.1), 294 (± 128.1) and 269 (± 68.4) μmol/kg W 0.75 for LZ, MZ and HZ, respectively. Urinary recovery of absorbed purine bases (PB) was calculated as the urinary recovery of a single dose of intrajugular infused uric acid (1,3- 15 N). In HZ crossbred cattle 83% (± 20.3) of infused uric acid was recovered in the urinary PD. The relationship between duodenal purine absorption (X, mmol/d) and urinary PD excretion (Y, mmol/d) was defined in HZ crossbred cattle as Y = 0.83 X + 0.269W 0.75 (± 85.1), assuming that the endogenous contribution was constant and independent of the exogenous PB supply. The activity of xanthine oxidase (EC 1.2.3.2.) was determined in HZ and MZ and was found to be higher in the liver (0.62 and 0.66 units/g, respectively) than in intestinal mucosa (0.09 and 0.03 units/g, respectively), whereas xanthine oxidase activity was practically absent in plasma of both cross breeds. The ratio PB:total N was determined in microbial extracts taken from rumen fluid of cows fed Bermuda grass (Cynodon dactylon) as the sole diet or supplemented (ratio of 80:20, grass: supplement) with gluten feed, soybean hulls or Gliricidia species and were found to range from 1.52-1.62 μmol PB/mg N.

    The objective of the present study was to evaluate the applicability of purine derivative (PD) method to Sri Lankan Zebu cattle and their crosses. In the first experiment four male Zebu cattle (LW 100 kg) were used to determine the response of PD excretion at four levels of intake (95, 80, 60 and 40% of the voluntary intake). Digestibility of dry matter and organic matter were not affected (P > 0.05) but nitrogen retention was increased with increasing levels of feed intake. The PD excretion were 1.91, 1.46, 1.21 and 0.66 mmol/kgW 0.75 /d for 95, 80, 60 and 40% of the voluntary intake levels, respectively. The proportion of allantoin in total PD was 82.6%. The excretion of creatinine was 1.05, 1.04, 0.92 and 0.84 mmol/kgW 0.75 /d, respectively. Daily output of total PD showed a positive response to the level of feed intake, while creatinine excretion was independent of dietary treatments. The correlation between PD excretion and digestible organic matter intake (DOMI) was significant (r 2 0.70). Nevertheless, the PDC index was affected (P > 0.05) by the level of feed intake and the correlation of the PDC index and DOMI was significant as well (r 2 =0.63). Results of spot urine analysis showed that the sampling period had little or no influence on the concentration of total PD or creatinine in urine. The PDC index was affected by the level of feed intake, but not by the time of sampling. In the second experiment, crossbred milking cows showed a higher PD excretion when fed with the experimental ration as compared with the farm ration. The mean PD excretion were 3.45 and 5.21 mmol/d for farm and experimental diets respectively. Allantoin accounted for more than 80% of the total PD, as in the previous experiment. In conclusion, urinary PD excretion appears to be a valid and non-invasive procedure to assess the microbial protein supply in local Zebu cattle and crossbred milking cows in Sri Lanka. Spot urine sampling also appeared to be a satisfactory method for

    Full Text Available Under conditions of intensive strengthening of globalization of world financial markets and deepening of the crisis, the main source of which are financial markets, financial derivatives market is rapidly developing. In such circumstances, we observe very active growing demand for tools, the main purpose of which is to reduce the financial risk – derivatives. Outlined trend has also involved Ukraine. In this connection, there is an objective need to develop estimate the interconnection of the money and stock markets and derivatives market. It should be kept in mind that achieving the outlined goal is possible only under condition of the full understanding of the scientific and methodological principles of the development of these markets. Purpose is to estimate the interconnection of the money and stock markets and derivatives market by building a mathematical model of system of structural equations that will promote the compilation of scientifically based program of derivatives market. Methodology. By using methods of economic-mathematical modelling were estimated the degree of influence of studied markets factors on financial derivatives market development and by changing this or that factor were predicted future trends of its operations. Results of the survey showed the current state and problems of derivatives market functioning. At the same time, our study allowed us to talk, that factors of the money and stock markets have a different impact on the derivatives market. So, the majority of money market factors have a reverse influence on the development of derivatives market. Instead, the stock market has a direct influence. Practical implications. The proposed scientific and methodical approach to evaluating the impact of factors on the derivatives market allows: influenced by different factors; to conduct a qualitative interpretation of the quantitative changes in the level of market development; to form a complete system of state

    Full Text Available This study aimed to investigate whether the world wide agreed models of valuation of derivates may be properly applied to the Romanian capital market, obtaining reliable results for decision makers. The most common valuation models take into account market data such as, interest and exchange rates, volatilities and the price of the underlying instrument. The procedures for valuation must clearly define the nature of the market data to be taken into consideration (for example the zero-coupon curve for the valuation of swaps and the independent reference base to be used (Reuters at a given time, bid/offer or mid price, broker. In order to be able to obtain the results, I based my study on a self-developed software which can calculate the price and characteristics for different types of derivatives securities once the primary data are filled in. I compared the results obatined usig the valuation models with the actual prices on the Romanian capital market. I expected that the results obtained to be more accurate as the parameters used in the calculation models properly reflect market data as at that date being as widely as possible.. These assumptions were only supported for certain value orientations. In conclusion, explanations for these results are given and limitations for this study are discussed. Also, suggestions for future research are presented in the final part of the article.

    In Experiment I, response of daily purine derivatives (PD) excretion to feed intake in Yerli Kara crossbred (YK-C) cattle on state farms was measured. Animals were fed a mixed diet containing 30% wheat straw and 70% compounded feed. Crude protein and organic matter contents of the diet were 12.4% and 95%, respectively. In Experiment II, spot urine sampling technique was applied at state farm. Four Yerli Kara crossbred bulls with a mean live weight of 211.0 ± 41.3 kg were used. The experimental design, feeding and diet were the same as in Experiment I. The treatments were allocated according to a 4 x 4 Latin Square design. In Experiment III, spot urine sampling technique was applied at smallholder farms. Two to three kg of compound feed (crude protein 12%) containing 65% barley, 25% bran, 6% sunflower seed meal, 3% marmer dust and 1% mineral and vitamin mixture was offered in two parts, one in the morning (0730 h) and the other in the afternoon (1700 h). The ingredients in the compound feed were similar for all animals, but animals in Groups I, II and III received 1 to 2 kg/d of straw (crude protein 3%), grass hay (crude protein 7%), or both straw and grass hay respectively. In Experiment I, a significant correlation (R 2 =0.99) between PD excretion (Y, mmol/d) and digestible organic matter intake, DOMI (X, kg/d) for YK-C cattle was observed (Y = 12.5 + 19.7 X). Moreover, daily PD excretion (mmol/d) was correlated with the PDC index, which was defined as [PD molar concentration] / [Creatinine molar concentration] x kgW 0.75 . In Experiment II, the PDC index increased with level of intake. The coefficient of variation due to time of sampling for uric acid, allantoin, PD, creatinine, total-N, the PDC Index in spot urine samples were less than 5%. In Experiment III, the PDC index were 49.95 ± 13.5, 45.6 ± 13.0, 48.95 ± 15.3 for the three groups respectively. These values were similar to those for 60% intake level in Experiment I. Using the equation DOMI = 344 + 48

  19. Derivative markets, speculation and oil prices

    International Nuclear Information System (INIS)

    2010-01-01

    Recent movements in oil prices have been ascribed by a number of analysts and political leaders not to market fundamentals but to the speculative positions taken by financial investors in derivatives markets. Various economists including Nobel Prize Paul Krugman believe however that the constitution of stocks is a necessary element for speculation, a feature that was not very evident during the sudden price increase in 2008; but these points of view are not entirely incompatible. Various explanations can be put forward, among which the most important is demand inertia. On the very short run, demand price elasticity is significantly lower than that usually calculated for the short term, which can significantly reduce the impact - on stocks - of a temporary price increase provoked by financial investors' behavior.

    The essential of derivatives has been discovered by researchers over recent decade. However, the conclusions made regarding the impact of derivatives on stock market volatility remains debatable. The main objective of this study is to examine the impact of derivatives on Malaysian stock market volatility by exploring FTSE Bursa Malaysia Kuala Lumpur Composite Index Futures (BMD FKLI) using FBM KLCI as the underlying asset. Generalized Autoregressive Conditional Heteroskedasticity (GARCH) (1, 1) model was employed to realize the objective. The results have shown that the introduction of futures trading has decreased the volatility of Malaysian stock market. The volatility increased vigorously during the Asian financial crisis compared to the Global financial crisis. However, the role of futures as a risk transfer is agreed as it could improve the market by decreasing the volatility in the spot market.

    It is well documented that stock markets are contagious. A negative shock to one market increases the probability of adverse shocks to other markets. We model this contagion effect by including mutually exciting jump processes in the dynamics of the indexes' log-returns. On top of this we add...... a stochastic volatility component to the dynamics. It is important to take the contagion effect into account if derivatives written on a basket of assets are to be priced or hedged. Due to the affine model specification the joint characteristic function of the log-returns is known analytically, and for two......-asset derivatives prices and show how for certain derivatives the impact is heavy. Moreover, we derive hedge ratios for European put and call options and perform a numerical experiment, which illustrates the impact of contagious jumps on option prices and hedge ratios.

  10. Time-zero efficiency of European power derivatives markets

    International Nuclear Information System (INIS)

    Peña, Juan Ignacio; Rodriguez, Rosa

    2016-01-01

    We study time-zero efficiency of electricity derivatives markets. By time-zero efficiency is meant a sequence of prices of derivatives contracts having the same underlying asset but different times to maturity which implies that prices comply with a set of efficiency conditions that prevent profitable time-zero arbitrage opportunities. We investigate whether statistical tests, based on the law of one price, and trading rules, based on price differentials and no-arbitrage violations, are useful for assessing time-zero efficiency. We apply tests and trading rules to daily data of three European power markets: Germany, France and Spain. In the case of the German market, after considering liquidity availability and transaction costs, results are not inconsistent with time-zero efficiency. However, in the case of the French and Spanish markets, limitations in liquidity and representativeness are challenges that prevent definite conclusions. Liquidity in French and Spanish markets should improve by using pricing and marketing incentives. These incentives should attract more participants into the electricity derivatives exchanges and should encourage them to settle OTC trades in clearinghouses. Publication of statistics on prices, volumes and open interest per type of participant should be promoted. - Highlights: •We test time-zero efficiency of derivatives power markets in Germany, France and Spain. •Prices in Germany, considering liquidity and transaction costs, are time-zero efficient. •In France and Spain, limitations in liquidity and representativeness prevent conclusions. •Liquidity in France and Spain should improve by using pricing and marketing incentives. •Incentives attract participants to exchanges and encourage them to settle OTC trades in clearinghouses.

    We examine the effects of energy derivatives trading on the crude oil market. There is a common public and regulatory perception that derivative securities increase volatility and can have a destabilizing effect on the underlying market. Consistent with this view, we find an abnormal increase in volatility for three consecutive weeks following the introduction of NYMEX crude oil futures. While there is also evidence of a longer-term volatility increase, this is likely due to exogenous factors, such as the continuing deregulation of the energy markets. Subsequent introductions of crude oil options and derivatives on other energy commodities have no effect on crude oil volatility. We also examine the effects of derivatives trading on the depth and liquidity of the crude oil market. This analysis reveals a strong inverse relation between the open interest in crude oil futures and spot market volatility. Specifically, when open interest is greater, the volatility shock associated with a given unexpected increase in volume is much smaller. (Copyright (c) 1999 Elsevier Science B.V., Amsterdam.

    This thesis studies electricity derivative markets from a view point of an electricity producer. The traditionally used asset pricing methods, based on the no arbitrage principle, are extended to take into account electricity specific features: the non storability of electricity and the variability in the load process. The sources of uncertainty include electricity forward curve, prices of resources used to generate electricity, and the size of the future production. Also the effects of competitors' actions are considered. The thesis illustrates how the information in the derivative prices can be used in investment and production planning. In addition, the use of derivatives as a tool to stabilize electricity dependent cash flows is considered. The results indicate that the information about future electricity prices and their uncertainty, obtained from derivative markets, is important in investment analysis and production planning.

    Full Text Available Developing short food supply chains for products from local pig (Sus scrofa domesticus breeds may offer chances for smallholders in rural areas to participate in niche markets and obtain additional income. Because the authenticity and distinctness of products are crucial for establishing marketing, this study compared selected product characteristics of pork from the Vietnamese Ban breed with pork from crossbreds, each derived at their typical market weight and from their respective extensive and semi-extensive production environment; thus resembling the combination, the products are available for customers. Traditional Ban pork could be effectively discriminated from crossbred pork through cut dimensions, exemplified by the significantly reduced loin eye area (P<0.001, and by the significantly reduced backfat thickness (P<0.001. Also, marbling fat was significantly decreased in local pork (P<0.001, whereas differences in further meat quality parameters were rather weakly expressed. The significantly higher share of polyunsaturated fatty acids in loins of traditionally produced Ban pigs (P=0.003 could possibly result in a preferred nutritional value, but lower oxidative stability of the products. This study provides novel information to improve the marketing of specialty pork in Vietnam and comparable situations in the Southeast Asian Massif.

    Full Text Available This study aimed to investigate dietary concentrate: forage ratios (C:F and undegraded dietary protein (UDP on nitrogen balance and urinary excretion of purine derivatives (PD in lambs. Four Dorper×thin-tailed Han crossbred castrated lambs with 62.3±1.9 kg body weight at 10 months of age were randomly assigned to four dietary treatments in a 2×2 factorial arrangement of two levels of C:F (40:60 and 60:40 and two levels of UDP (35% and 50% of CP, according to a complete 4×4 Latin-square design. Each experimental period lasted for 19 d. After a 7-d adaptation period, lambs were moved into individual metabolism crates for 12 d including 7 d of adaption and 5 d of metabolism trial. During the metabolism trial, total urine was collected for 24 h and spot urine samples were also collected at different times. Urinary PD was measured using a colorimetric method and creatinine was measured using an automated analyzer. Intake of dry matter (DM (p0.05 while urinary N increased as the level of UDP decreased (p0.05 or interaction between dietary treatments (p>0.05. Daily excretion of creatinine was not affected by dietary treatments (p0.05 and a good correlation was found between the PDC index (average value of three times of spot urine and daily excretion of PD (R2 = 0.88. These results suggest that for animals fed ad libitum, the PDC index in spot urine is effective to predict daily excretion of PD. In order to improve the accuracy of the spot sampling technique, an appropriate lag phase between the time of feeding and sampling should be determined so that the sampling time can coincide with the peak concentration of PD in the urine.

    Full Text Available The capital market is unarguably the most robust institution in any economy notable for mobilizing the necessary fund for financing long-term productive project. It controls relatively large amounts of capital and represent the largest institutional providing long-term credits for capital project like real estate that requires huge capital outlay. This study therefore, attempts an investigation into the effectiveness of capital market derivatives in housing delivery in Lagos. An empirical survey research was conducted in Lagos, using a random sampling technique with a structured questionnaire to collect data from 147 respondents comprising 89 stockbrokers and 58 real estate developers in Lagos mega-city. Data collected were analyzed with SPSS using descriptive and inferential statistics. The result revealed that 56.7% of the observed variations in housing delivery (R2= 0.567; p< 0.05 is explained by capital market derivatives, which suggests that, proper utilization of capital market derivatives will enhance and improve housing delivery in Nigeria. However, this is not been adequately used by developers of real estate projects in the study. Thus, the study recommends amongst other remedial steps that a synergetic effort should be created between the capital market and real estate developers which will enhance effective housing delivery, the development of people and the Nation.

  19. Market information and price volatility in petroleum derivatives spot and future markets

    International Nuclear Information System (INIS)

    Khalid Nainar, S.M.

    1993-01-01

    This paper examines the relationship between petroleum futures trading, market information and spot prices. It tests the hypothesis that there is increased spot market information with futures trading of various petroleum derivatives for weekly data during the period January 1970 to July 1985 at the new York Mercantile Exchange. Increased market information with futures trading is indicated by the insignificance of coefficients of past prices in spot price regressions in periods with futures trading. However, the estimates of the coefficient of variation indicate that price volatility tends to increase with futures trading. Thus, traders seem better informed with futures trading although the advantages of increased market information might potentially be undermined by increased price volatility as in the case of regular gasoline.

    The implementation of renewable energies to the electricity market is inefficient and expensive with current measures. Further these measures are prejudicial for the existing energy-only-market. The combination of fluctuating and controllable renewable powers in virtual power plants enables the marketing of this power as a derivate on the future market. Thus would relieve the spot market and stabilize pricing on both markets. Subsequently the renewable energy obligation will reduce and renewable energies could be marketed as secured power.

  2. Essays on pricing electricity and electricity derivatives in deregulated markets

    Science.gov (United States)

    Popova, Julia

    2008-10-01

    This dissertation is composed of four essays on the behavior of wholesale electricity prices and their derivatives. The first essay provides an empirical model that takes into account the spatial features of a transmission network on the electricity market. The spatial structure of the transmission grid plays a key role in determining electricity prices, but it has not been incorporated into previous empirical models. The econometric model in this essay incorporates a simple representation of the transmission system into a spatial panel data model of electricity prices, and also accounts for the effect of dynamic transmission system constraints on electricity market integration. Empirical results using PJM data confirm the existence of spatial patterns in electricity prices and show that spatial correlation diminishes as transmission lines become more congested. The second essay develops and empirically tests a model of the influence of natural gas storage inventories on the electricity forward premium. I link a model of the effect of gas storage constraints on the higher moments of the distribution of electricity prices to a model of the effect of those moments on the forward premium. Empirical results using PJM data support the model's predictions that gas storage inventories sharply reduce the electricity forward premium when demand for electricity is high and space-heating demand for gas is low. The third essay examines the efficiency of PJM electricity markets. A market is efficient if prices reflect all relevant information, so that prices follow a random walk. The hypothesis of random walk is examined using empirical tests, including the Portmanteau, Augmented Dickey-Fuller, KPSS, and multiple variance ratio tests. The results are mixed though evidence of some level of market efficiency is found. The last essay investigates the possibility that previous researchers have drawn spurious conclusions based on classical unit root tests incorrectly applied to

    Full Text Available The market of derivative tools becomes an integral part of the financial market, the functions which are carrying out in it peculiar only to it: hedging, distribution of risks, ensuring liquidity of basic assets, information support of future movement of the prices, decrease in asymmetry of information in the financial markets. However, the insufficiency or lack of transparent information can lead to emergence of the crisis phenomena, shocks in the financial market and growth of system risk. Emergence of need for strengthening of information function of the market of derivatives changes of requirements to transparency of information had been caused by financial crisis of 2008-2009. In this article the attempt of an assessment of influence was made by means of autoregressive models the change of requirements to standard transparency, such as qualitative characteristic of the derivatives market, on quantitative indices of the financial market, in particular financial depth. The results of research demonstrate that reforming of the legislation concerning strengthening of transparency in the derivatives market positively influences the growth of financial depth. The research of this question will promote the best understanding of importance of reforming of regulation of the derivatives market, in particular strengthening of requirements to transparency. Recommendations of the further researches concern the needs of input of reforms of financial regulation in the derivatives market in Ukraine, and, thus, to provide the corresponding conditions for his development

    2014-01-01

    This study examines intraday relationships among the spot index, index futures, and the implied volatility index based on the VAR(1)-asymmetric BEKK-MGARCH model. Analysis of a high-frequency dataset from the Korean financial market confirms that there is a strong intraday market linkage between the spot index, KOSPI200 futures, and VKOSPI and that asymmetric volatility behaviour is clearly present in the Korean market. The empirical results indicate that the futures return shock affects the spot market more severely than the spot return shock affects the futures market, though there is a bi-directional causal relationship between the spot and futures markets. Our results, based on a high-quality intraday dataset, satisfy both the positive risk-return relationship and asymmetric volatility effect, which are not reconciled in the frameworks of previous studies.

    Full Text Available Analysing the possibility of creations and prospects of weather derivatives development on the domestic market the first of all should be identify the business areas that are strongly exposed for weather risk, which are: energy, agricultural, building and transportation. The specificity of the Polish climate is the high volatility of the major weather factors like temperature or precipitations. Similar to other European countries where weather derivatives markets already exist (e.g.: Germany, France, and United Kingdom. Having in mind dynamic grow of companies with regards to management processes, used technologies and marketing strategies, the exposure for weather risk is getting higher. Therefore, there is a strong pressure for creation of mechanisms and instruments that will allow reducing that kind of risks. Currently in Poland there are no conditions for development of weather derivatives market due to lack of demand. That situation is caused by low level of awareness regarding to possibilities of reducing weather risks. Within a few years the demand for such the instruments will appear ñ together with growing awareness. Once the demand for weather derivative will appear, the existing infrastructure of financial sector is ready for its implementation. Of course it is hard to say what will be the direction of whether derivatives grow on the domestic financial market but taking into consideration its dynamic grow and strong correlations with global markets, there is a small probability that weather derivatives will not appear on the Polish market ñ it is only the matter of time.

  16. Modeling spot markets for electricity and pricing electricity derivatives

    Science.gov (United States)

    Ning, Yumei

    Spot prices for electricity have been very volatile with dramatic price spikes occurring in restructured market. The task of forecasting electricity prices and managing price risk presents a new challenge for market players. The objectives of this dissertation are: (1) to develop a stochastic model of price behavior and predict price spikes; (2) to examine the effect of weather forecasts on forecasted prices; (3) to price electricity options and value generation capacity. The volatile behavior of prices can be represented by a stochastic regime-switching model. In the model, the means of the high-price and low-price regimes and the probabilities of switching from one regime to the other are specified as functions of daily peak load. The probability of switching to the high-price regime is positively related to load, but is still not high enough at the highest loads to predict price spikes accurately. An application of this model shows how the structure of the Pennsylvania-New Jersey-Maryland market changed when market-based offers were allowed, resulting in higher price spikes. An ARIMA model including temperature, seasonal, and weekly effects is estimated to forecast daily peak load. Forecasts of load under different assumptions about weather patterns are used to predict changes of price behavior given the regime-switching model of prices. Results show that the range of temperature forecasts from a normal summer to an extremely warm summer cause relatively small increases in temperature (+1.5%) and load (+3.0%). In contrast, the increases in prices are large (+20%). The conclusion is that the seasonal outlook forecasts provided by NOAA are potentially valuable for predicting prices in electricity markets. The traditional option models, based on Geometric Brownian Motion are not appropriate for electricity prices. An option model using the regime-switching framework is developed to value a European call option. The model includes volatility risk and allows changes

    2013-01-01

    Highlights: • The impact of market concern derived from the Web on oil volatility is analysed. • It has an equilibrium relationship between oil prices and long-run market concern. • The short-run market concerns have an asymmetric influence on oil price volatility. • The Internet can exaggerate the impact of information shocks on oil price. - Abstract: With the acceleration of oil marketisation and the rapid development of electronic information carriers, external information shocks can be easily and quickly transmitted to the oil market through the Internet. This paper analyses the impact of short- and long-run market concerns, derived from search query volumes in Google for different domains around the oil market on oil volatility using co-integration and the modified EGARCH model. Empirical results suggest there is a long-term equilibrium relationship between oil prices and long-run market concern for oil prices and oil demand. The short-run market concerns for the 2008 financial crisis and the Libyan war convulsion have a significant and asymmetric influence on oil price volatility. This indicates that market concern transmitted through the Internet can strengthen the linkage between oil price changes and external events by influencing the expectation of market traders, and to some extent it can exaggerate the impact of nonfundamental information shocks

    This conference was devoted to a discussion about the likely impacts of deregulation on electricity markets in North America. Many of the presentations emphasized price risk in a competitive open access energy market. It was noted that deregulation is frequently associated with the creation of larger companies, higher risks and lower costs. Some of the individual topics addressed by the speakers included discussion of : (1) how underlying physical markets will work in Ontario, (2) experiences in derivative trading in the natural gas industry, (3) how to create value through multiple commodity risk management products, (4) trading with energy derivatives in the U.S. (5) how derivatives can add value for municipal electrical utilities, and (6) risk management mechanisms for energy derivative trading. refs., tabs., figs

    For some species, animal production systems are based on the use of crossbreeding to take advantage of the increased performance of crossbred compared to purebred animals. Effects of single nucleotide polymorphisms (SNPs) may differ between purebred and crossbred animals for several reasons: (1) differences in linkage disequilibrium between SNP alleles and a quantitative trait locus; (2) differences in genetic backgrounds (e.g., dominance and epistatic interactions); and (3) differences in environmental conditions, which result in genotype-by-environment interactions. Thus, SNP effects may be breed-specific, which has led to the development of genomic evaluations for crossbred performance that take such effects into account. However, to estimate breed-specific effects, it is necessary to know breed origin of alleles in crossbred animals. Therefore, our aim was to develop an approach for assigning breed origin to alleles of crossbred animals (termed BOA) without information on pedigree and to study its accuracy by considering various factors, including distance between breeds. The BOA approach consists of: (1) phasing genotypes of purebred and crossbred animals; (2) assigning breed origin to phased haplotypes; and (3) assigning breed origin to alleles of crossbred animals based on a library of assigned haplotypes, the breed composition of crossbred animals, and their SNP genotypes. The accuracy of allele assignments was determined for simulated datasets that include crosses between closely-related, distantly-related and unrelated breeds. Across these scenarios, the percentage of alleles of a crossbred animal that were correctly assigned to their breed origin was greater than 90 %, and increased with increasing distance between breeds, while the percentage of incorrectly assigned alleles was always less than 2 %. For the remaining alleles, i.e. 0 to 10 % of all alleles of a crossbred animal, breed origin could not be assigned. The BOA approach accurately assigns

    2018-05-01

    Full Text Available We model the logarithm of the spot price of electricity with a normal inverse Gaussian (NIG process and the wind speed and wind power production with two Ornstein–Uhlenbeck processes. In order to reproduce the correlation between the spot price and the wind power production, namely between a pure jump process and a continuous path process, respectively, we replace the small jumps of the NIG process by a Brownian term. We then apply our models to two different problems: first, to study from the stochastic point of view the income from a wind power plant, as the expected value of the product between the electricity spot price and the amount of energy produced; then, to construct and price a European put-type quanto option in the wind energy markets that allows the buyer to hedge against low prices and low wind power production in the plant. Calibration of the proposed models and related price formulas is also provided, according to specific datasets.

    The study aims at testing the weak form of Efficient Market Hypothesis in the context of an emerging commodity market - National Commodity Derivatives Exchange (NCDEX), which is considered as the prime commodity derivatives market in India. The study considered daily spot and futures prices of five selected commodities traded on NCDEX over 12 month period (the futures contracts originating and expiring during the period January 2011 to December 2011) The five commodities chosen are Pepper, Crude palm Oil, steel silver and Chana as they account for almost two-thirds of the value of agricultural commodity derivatives traded on NCDEX. The results of Run test indicate that both spot and futures prices are weak form efficient

    Smallholder dairy production represents a promising income generating activity for poor farmers in the developing world. Because of the perishable nature of milk, marketing arrangements for collection, distribution and sale are important for enhanced livelihoods in the smallholder dairy sector. In this study we examined the relationship between market quality and basic feeding and breeding practices at farm level. We define market quality as the attractiveness and reliability of procurement channels and associated input supply arrangements. We took as our study countries, India with its well-developed smallholder dairy sector, and Ethiopia where the smallholder dairy industry has remained relatively undeveloped despite decades of development effort. We conducted village surveys among producer groups in 90 villages across three States in India and two Regions in Ethiopia. Producer groups were stratified according to three levels of market quality - high, medium and low. Data showed that diet composition was relatively similar in India and Ethiopia with crop residues forming the major share of the diet. Concentrate feeding tended to be more prominent in high market quality sites. Herd composition changed with market quality with more dairy (exotic) cross-bred animals in high market quality sites in both India and Ethiopia. Cross-bred animals were generally more prominent in India than Ethiopia. Herd performance within breed did not change a great deal along the market quality gradient. Parameters such as calving interval and milk yield were relatively insensitive to market quality. Insemination of cross-bred cows was predominantly by artificial insemination (AI) in India and accounted for around half of cross-bred cow inseminations in Ethiopia. Data on perceptions of change over the last decade indicated that per herd and per cow productivity are both increasing in high market quality sites with a more mixed picture in medium and low-quality sites. Similarly dairy-derived

    Full text: Ultrasonography and a structured questionnaire were used in a cross-sectional study to gather data on the prevalence and risk factors for anestrus in crossbred cows at ≥60 days postpartum in 273 smallholder farms. The prevalence of anestruc was 18%. The odds ratio (OR) for true anestrus was 17.52 and 2.81 times higher (P < 0.05) in cows with poor (≤2.0) and excessive (>3.5) body condition score (BCS), respectively, compared to those with optimal BCS (2.5-3.5), 2.82 times higher in suckled than in nonsuckled cows (P = 0.03), and 2.53 times higher in cows that calved during the cold season than in those that calved during the hot season (P = 0.03). The OR for anestrus was 1.62 times higher (P = 0.017) in cows managed by an employee than in those managed by the farmers themselves (P = 0.001), and 2.66 times higher (P = 0.003) in small farms (≤5 cows) than in large farms (≥11 cows). The OR was 0.71 to 0.46 times lower in farms having a guaranteed market to sell milk than those with an uncertain traditional milk market (P < 0.05). Maintaining optimal BCS of cows, farmers' training on management of cattle reproduction, and development of a market linkage to sell milk would improve the number of cows for breeding by 60 days postpartum.

    2012-01-01

    The efficiency of the Iberian Energy Derivatives Market in its first five and a half years is assessed in terms of volume, open interest and price. The continuous market shows steady liquidity growth. Its volume is strongly correlated to that of the Over The Counter (OTC) market, the amount of market makers, the enrolment of financial agents and generation companies belonging to the integrated group of last resort suppliers, and the OTC cleared volume in its clearing house. The hedging efficiency, measured through the ratio between the final open interest and the cleared volume, shows the lowest values for the Spanish base load futures as they are the most liquid contracts. The ex-post forward risk premium has diminished due to the learning curve and the effect of the fixed price retributing the indigenous coal fired generation. This market is quite less developed than the European leaders headquartered in Norway and Germany. Enrolment of more traders, mainly international energy companies, financial agents, energy intensive industries and renewable generation companies is desired. Market monitoring reports by the market operator providing post-trade transparency, OTC data access by the energy regulator, and assessment of the regulatory risk can contribute to efficiency gains. - Highlights: ► The continuous traded volumes in the Iberian power futures market grow steadily. ► Those volumes are correlated to OTC volumes and the enrolment of key players. ► Most liquid contracts show the smallest hedging ratio. ► Regulation fixing the coal fired generation price affects spot and forward prices. ► The overall efficiency can grow via market monitoring reports and OTC data access.

    Full Text Available The Credit Default Swap (CDS market has both been lauded for its ability to stabilize the financial system through credit risk transfers and been the source of regulatory concern due to its size and lack of transparency. As a decentralized over-the-counter market, detailed information about pricing mechanisms is rather scarce. To investigate reported CDS prices (spreads more closely, we make use of empirical First Significant Digit (FSD distributions and analyze daily CDS prices for European and US entities during the financial crisis starting in 2007. We find that on a time-aggregated level, the European and US markets obey empirical FSD distributions similar to the theoretical ones. Surprising differences are observed in the development of the FSD distributions between the US and European markets. Whereas the FSD distribution of the US derivative market behaves nearly constantly during the last financial crisis, we find huge fluctuations in the FSD distribution of the European market. One reason for these differences might be the possibility of strategic default for US companies due to Chapter 11 and avoided contagion effects.

    First, this paper estimates the dimensions of the market for cannabis in Spain using data on the extent of consumption and the main patterns of use of consumers. Then the paper reviews the hypothetical production and distribution costs of these drugs in different production regimes under different legal conditions. The review shows that current prices of cannabis in the illegal market could be notably reduced if production and distribution of cannabis were decriminalized and even more if they were performed by legal enterprises. Thirdly, we examine the relationship between prices and consumption levels by analysing the price elasticity of demand. A fall in the prices of cannabis products will likely result in an increase in the number of users and in the total amount consumed. Lastly we consider several alternatives for the taxation of cannabis derivatives to counteract the likely fall in prices, and their pros and cons.

    The implementation of renewable energies to the electricity market is inefficient and expensive with current measures. Further these measures are prejudicial for the existing energy-only-market. The combination of fluctuating and controllable renewable powers in virtual power plants enables the marketing of this power as a derivate on the future market. Thus would relieve the spot market and stabilize pricing on both markets. Subsequently the renewable energy obligation will reduce and renewable energies could be marketed as secured power.

    Full Text Available A study on eating behavior of Ongole Crossbred (OC and Limousin Crossbred (LC steers (aged 9 months fed fermented rice straw and concentrate has been carried out. Rice straw and concentrate were given in 60:40 ratio. Rice straw was fermented by commercial starter (BioP 2000 Z, while concentrate was composed of commercial concentrate and soybean pulp (by-product of soy-sauce industry. The diet was set to meet the dry matter (DM requirement at 3.0% of liveweight. Eating behaviour was measured from 3 days continuously observation. Chewing number was accounted by halter equipped with tape-switch in jaw side and was recorded every 1/10 second in connected PC. The results showed that DMI of both OC (3.21 kg and LC (4.18 kg was similar, being 2.8% LW. However, chewing number of OC (133808 chews/d was higher than that of LC (106353 chews/d. Chewing for eating and for rumination in OC (86995 and 46813 chews was higher than of LC (67628 and 38725 chews. Chewing efficiency for eating in OC (0.041 g DMI/chew was lower than that of LC (0.066 g DMI/chew. Similar tendency was observed in chewing efficiency for rumination that OC (0.080 g DMI/chew was lower than that of LC (0.109 g DMI/chew. The conclusion is LC has a better chewing efficiency than of OC and it was pointed to different jaw size between OC and LC.

  8. North America markets for alcohol and alcohol-derived motor fuels and need for tax incentives

    International Nuclear Information System (INIS)

    Haigwood, B.

    1991-01-01

    The U.S. fuel alcohol and ether industry has grown from its infancy in 1979 to approximately 2.9 billion gallons of production capacity in 1991. With the emphasis on clean air, the uncertainties in the Middle East, and fluctuating oil prices, IRI believes the demand for alcohol-derived motor fuels is poised to begin a second phase of expansion. Historically, the two primary alcohol-derived motor fuels sold in the U.S. have been methyl tertiary butyl ether (MTBE) and ethanol. There is also a limited but growing use of methanol as 85% blendstock for gasoline. Since 1978, fuel ethanol has provided the U.S. petroleum industry with an additional source of supply, octane, and profit. Its price was based on the price of wholesale gasoline plus available federal and state tax incentives. These incentives allowed ethanol, with production costs of $1.00 to $1.25 per gallon, to compete with gasoline at prices of 40 to 65 per gallon. Without the federal and state tax incentives, it would not be economically feasible to sell or manufacture fuel ethanol. On the other hand, the largest consumption of methanol has been as a feedstock for the production of MTBE, the world's fastest growing chemical over the past seven years. MTBE prices are based on the cost of raising the octane level of gasoline, and this commodity does not receive subsidies. Beginning in 1992, IRI predicts the price relationship between ethanol, MTBE, and gasoline will change as U.S. refiners and marketers are required to include oxygenated fuels (alcohol-derived) in their gasoline. In total, over 60 billion gallons of gasoline will need to be reformulated by the year 2000. The increased demand for oxygen will result in a 2.5-billion gallon deficit of MTBE and 1.2-billion gallon deficit of ethanol by the year 2000. 2 tabs

    2014-06-01

    Full Text Available This study compared the adaptation traits in common crosses of crossbred dairy cattle in central Brazil. Twenty animals of each of three genetic groups were used: zebu (Bos indicus, Simmental x Zebu (SZ and Holstein x Zebu (HZ. The test measured variations in rectal temperature (RT, respiration rate (RR and heart rate (HR of animals in the shade and after exposure to the sun, as well as mean daily milk production throughout the lactation period. The procedure was repeated three times. There were significant interactions between test group and genetic group for the traits investigated and the correlations among traits were low. The RR of the crossbred groups may be controlling body temperature in such a way as not to cause an increase in RT. Milk production influenced RR in crossbred cows exposed to the sun, confirming their poorer adaptation in comparison with zebu cows. We observed that the adaptation can be measured in terms of production within the same genetic group. In conclusion, the crosses with European breeds produced more milk than zebu, although they were influenced by heat/solar radiation.

    Bio-oil (biomass fast pyrolysis) systems for heat, power or CHP production are nearing demonstration status. Their commercial attractiveness will depend on many factors, and will vary with the application, the scale, and importantly the location and its associated economic and logistical factors. The objective of this work, carried out as part of an EC-ALTENER project, was to evaluate the opportunities for bio-oil in the heat and power markets of Europe. Bio-oil applications were compared with conventional (fossil) alternatives for the same heat and power duty. The evaluation was carried out by a quantitative assessment of the economic competitiveness of standard applications in 14 European countries. Location-specific data were collected, and combined with technology-specific data obtained from earlier work. A competitiveness factor (c F ) was derived which represents the total annual cost of a conventional alternative relative to a bio-oil application. The results showed a wide variation across Europe. A total of six countries had at least one bio-oil application which was economically competitive. Heat-only applications were found to be the most economically competitive, followed by CHP applications, with electricity-only applications only very rarely competitive. For a given technology, the larger the scale, the better the competitiveness

The marketing concept makes the patient and the patients' needs the ultimate criteria of marketing efforts. Myths and good practices for effective marketing that will promote oral health are described under the traditional four "Ps" categories of "product" (best dental care), "place" (availability), "promotion" (advertising and other forms of making patients aware of available services and how to use them), and "price" (the total cost to patients of receiving care).

Materials and Methods: Total 36 ejaculates (3 ejaculates from each bull) were collected from 6 pure Jersey and 6 crossbred Jersey bulls and evaluated for various seminal attributes during neat, pre-freeze, and post-freeze semen. Results: The mean (±standard error [SE]) values of neat semen characteristics in pure and crossbred Jersey bulls were recorded such as volume (ml), color, consistency, mass activity (scale: 0-5), and sperm concentration (millions/ml). The extended semen was further investigated at pre-freeze and post-freeze stages and the mean (±SE) values recorded at neat, pre-freeze, and post-freeze semen were compared between pure and crossbred Jersey bulls; sperm motility (80.55±1.70%, 62.77±1.35%, 46.11±1.43% vs. 80.00±1.80%, 65.00±1.66%, 47.22±1.08%), live sperm count (83.63±1.08%, 71.72±1.09%, 58.67±1.02% vs. 80.00±1.08%, 67.91±1.20%, 51.63±0.97%), total abnormal sperm count (8.38±0.32%, 12.30±0.39%, 16.75±0.42% vs. 9.00±0.45%, 12.19±0.48%, 18.11±0.64%), hypo-osmotic swelling (HOS) reacted spermatozoa (71.88±0.77%, 62.05±0.80%, 47.27±1.05% vs. 72.77±1.02%, 62.11±0.89%, 45.94±1.33%), acrosome integrity (89.05±0.83%, 81.33±0.71%, 71.94±0.86% vs. 86.55±0.57%, 78.66±0.42%, 69.38±0.53%), and DNA integrity (99.88±0.07%, 100, 99.66±0.11% vs. 99.94±0.05%, 100, 99.44±0.18%,). The volume, color, consistency, sperm concentration, and initial motility in pure and crossbred Jersey bulls did not differ significantly (p>0.05). The mass activity was significantly (p0.05) was observed in abnormal sperm; HOS reacted spermatozoa and DNA integrity percentage among breeds. Conclusion: It may be concluded that the quality of pure Jersey bull semen was comparatively better than the crossbred Jersey bulls. PMID:27047028

    Full Text Available Aim: The present study was carried out to investigate the relationship between blood serum concentrations of macro and micro minerals and development of retention of placenta (ROP in crossbred cattle. Materials and Methods: The present study was carried out at Instructional Livestock Farm, Bihar Veterinary College and local Khatals in and around Patna. A total of 20 crossbred cattle (n=10 with normal expulsion of the placenta as control and n=10 with ROP were selected in the present study. Blood samples were collected from these animals and serum was separated and stored in the deep freezer at −20°C till further analysis. The estimation of serum macro-minerals (Ca, P, Ca/P ratio was done by Span diagnostic Kits (Surat, India and trace minerals or micro-minerals (Zn, Cu, and Fe were analyzed by atomic absorption spectrophotometer (Perkin Elmer AAS 220. Mean values were compared between both the groups at 0 h (at parturition and 12 h after parturition. Results: The mean values of serum calcium and zinc were found significantly lower in cattle having ROP than control at both 0 h and 12 h after parturition. The mean values of serum Ca and P ratio obtained at 0 hour were significantly lower in ROP groups as compared to control groups and non-significant at 12 h. The mean values of serum inorganic phosphorus, copper and iron was found non-significantly lower in ROP cases as compared to control. Conclusions: Macro and micro mineral deficiency such as calcium, iron, zinc and copper in blood serum may be predisposing factor for the occurrence of retention of placenta in crossbred cattle.

    Market trend data show that the media marketplace continues to rapidly evolve. Recent research shows that substantial portions of the U.S. media population are "new media" users. Today, more than ever before, media consumers are exposed to multiple media at the same point in time, encouraged to participate in media content generation, and challenged to learn, access, and use the new media that are continually entering the market. These media trends have strong implications for how consumers of health information access, process, and retain health-related knowledge. In this article we review traditional information processing models and theories of interpersonal and mass media access and consumption. We make several theory-based propositions for how traditional information processing and media consumption concepts will function as new media usage continues to increase. These propositions are supported by new media usage data from the Centers for Disease Control and Prevention's entry into the new media market (e.g., podcasting, virtual events, blogging, and webinars). Based on these propositions, we conclude by presenting both opportunities and challenges that public health communicators and marketers will face in the future.

    2016-02-01

    Full Text Available The increased uncertainty in the country’s economy, impossibility of raising capital only by standard financial instruments substantiated the need for such financial innovations as derivatives. The relevance of the suggested topic is justified by the lack of strong legislative framework regulating the market of derivative financial instruments, as well as by significant demand for them in Ukraine. The aim of the article is to analyze the development level of the normative and legal field of trade in the derivatives market as well as the quality of the formed system of main indicators for derivatives trading in Ukraine. The paper identifies the problem, which could be neutralized through the use of derivative financial instruments. The volume and structure of the world and domestic derivatives markets have been analyzed. Based on the analysis of the legal field of regulating the market of derivative financial instruments as well as statistical analysis of its volume and structure, the reasons for the low activity in the considered market have been justified and recommendations to improve the current situation proposed.

    2017-04-01

    Full Text Available This paper empirically examines whether commodity derivatives can be used as an alternative investment asset in India where commodity markets are at emerging state and provides the same diversification benefit as they provide in developed commodity markets. In India only commodity futures are prevalent so various commodity indices representing various sectors has been used in the study. Diversification aspect of commodity derivatives has been tested initially by using correlation analysis. Compounded Daily Growth rate and Relative Standard deviation has been used as a measure of calculating risk and return of daily data of SENSEX, BOND and four Commodity Indices (MCX Comdex, MCX AGRI, MCX Metal, MCX Energy. Markowitz Efficient Frontier theory has been used to calculate portfolio risk return and Sharpe risk adjusted ratio has been used to evaluate the various portfolios. Optimal portfolio has been obtained for the combination of equity, bond and commodity and overall results of the study indicate that an investor who is risk averse will prefer to invest in combination of SENSEX, BOND & MCX Energy whereas an investor who gets utility by taking more risk for more returns will prefer to invest in combination of SENSEX, BOND & MCX Metal. Investor having inclination towards moderate risk return would tend to invest in MCX AGRI along with SENSEX and BOND.

    Breed-specific effects are observed when the same allele of a given genetic marker has a different effect depending on its breed origin, which results in different allele substitution effects across breeds. In such a case, single-breed breeding values may not be the most accurate predictors of crossbred performance. Our aim was to estimate the contribution of alleles from each parental breed to the genetic variance of traits that are measured in crossbred offspring, and to compare the prediction accuracies of estimated direct genomic values (DGV) from a traditional genomic selection model (GS) that are trained on purebred or crossbred data, with accuracies of DGV from a model that accounts for breed-specific effects (BS), trained on purebred or crossbred data. The final dataset was composed of 924 Large White, 924 Landrace and 924 two-way cross (F1) genotyped and phenotyped animals. The traits evaluated were litter size (LS) and gestation length (GL) in pigs. The genetic correlation between purebred and crossbred performance was higher than 0.88 for both LS and GL. For both traits, the additive genetic variance was larger for alleles inherited from the Large White breed compared to alleles inherited from the Landrace breed (0.74 and 0.56 for LS, and 0.42 and 0.40 for GL, respectively). The highest prediction accuracies of crossbred performance were obtained when training was done on crossbred data. For LS, prediction accuracies were the same for GS and BS DGV (0.23), while for GL, prediction accuracy for BS DGV was similar to the accuracy of GS DGV (0.53 and 0.52, respectively). In this study, training on crossbred data resulted in higher prediction accuracy than training on purebred data and evidence of breed-specific effects for LS and GL was demonstrated. However, when training was done on crossbred data, both GS and BS models resulted in similar prediction accuracies. In future studies, traits with a lower genetic correlation between purebred and crossbred

    The experiment was carried out during August (hot climate) on twelve pregnant cows, six crossbred (50% native Baladi and 50% Brown Swiss) and six native Baladi pregnant cows in the same age and second parity during their mid-pregnancy as detected by rectal palpation. The experiment was repeated during December (mild climate) on similar twelve pregnant cows. Blood sample was obtained from each cow at the end of August (first group) and at the end of December (second group) to determine blood plasma levels of two thermogenic hormones (total T3 and cortisol) and biochemical parameters, total protein, creatinine, urea-N, triglycerides, ALT and AST. Comparison was made between hot group and mild group to estimate heat induced changes in both breeds and to identify which breed is more tolerant to heat stress. The results showed that heat- induced a significant decrease (p<0.01) in plasma level of total T3 in crossbred and Baladi by (-53.6 and -51.8%), respectively and triglycerides in crossbred and Baladi by (-35.6 and-32.2%), respectively. But hot weather caused a significant increase (p<0.01) in cortisol hormone level in crossbred and Baladi by (78.3 and 77.6%), respectively. Significant (p<0.01) difference between crossbred and Baladi cows in cortisol hormone level was remarked. Moreover, a significant increase (p<0.01) in total protein level in crossbred and Baladi by (11.4 and 13.4%), respectively was observed. An increase (p<0.05) was noticed in creatinine level by 25.0% and 20.1% in crossbred and Baladi, respectively, urea-N level in crossbred and Baladi by 16.6% and 21.7%, respectively and ALT in crossbred and Baladi by 42.4% and 45.7%, respectively. Also, a difference was recognized amounted in AST level in crossbred and Baladi by 22.3 %, (p<0.02) and 31.0 % (p<0.01), respectively.

    Crossbreeding is an effective method of improving the efficiency and profit of production in commercial pig operations. To understand the effect of crossbreeding on meat and nutrient quality, a combination including three purebred (Duroc, D; Landrace, L; Yorkshire, Y) and two crossbred pig lines (Landrace × Yorkshire, LY; Duroc × (Landrace × Yorkshire), DLY) frequently used internationally were studied. The results showed that meat from the LY and DLY crosses had lower values for lightness L24h∗, shear force and epinephrine and higher values for drip loss, C18:1, insulin, glucagon and monounsaturated fatty acids than D, L and Y pigs. Moreover, LY had higher values for post mortem pH and lower values for a* and b* than the purebreds. In contrast, DLY had lower values for pH and higher values for a* and b* than the purebreds. Meat quality-related gene analysis showed that the CAST, IGF2 and MC4R gene expression levels in the LY and DLY pigs were significantly higher than those in the D, L and Y pigs. These results indicate that crossbreeding can alter the meat quality, nutritive value, energy metabolism and gene expression of pigs. Future research should focus on microRNA expression and DNA methylation that regulate gene expression and thus affect the meat quality. © 2017 Japanese Society of Animal Science.

    2007-01-01

    Full Text Available This paper presents a spatial price equilibrium model in an oligopoly market for refined oil products. Till 1997 the Brazilian oil market was characterized by the state monopoly of Petrobras, which up to 2001 remained the only firm authorized to import oil derivatives. With several agents operating in the primary oil supply market, the government stopped fixing the prices for Petrobras, which started to determine the prices based on competition with other players. In this new scenario some questions arise regarding the price levels at which refined products will be supplied in different regions across Brazil as well as the capacity of national refineries to compete with imported products. To answer those and other questions, a new oligopoly spatial equilibrium model is herein proposed, taking into account the special characteristics of production of refined oil products. An iterative Gauss-Seidel-like algorithm with sequential adjustments was developed and applied to Brazilian market data. The model, the algorithm and its application are described in this work. Such a model may be used both by regulatory authorities and by companies in the sector.Este artigo apresenta um modelo de equilíbrio espacial de preços em um mercado oligopolizado de derivados de petróleo. Até o ano de 1997, o mercado brasileiro era caracterizado pelo monopólio estatal da Petrobrás, a qual permaneceu, até 2001, como a única empresa autorizada a importar derivados de petróleo. Com vários agentes operando no mercado, o governo deixou de fixar os preços para a Petrobrás, que passou a determinar os preços baseada na competição com outros agentes. Neste cenário, surgem algumas questões relativas aos níveis de preços a serem oferecidos no mercado e relativas à capacidade das refinarias nacionais de competir com produtos importados. Para responder a estas e outras questões, um novo modelo de equilíbrio espacial de preços para um mercado oligopolizado foi

    A total of 1922 first generation crossbred cows born between 2005 and 2012 produced by inseminating purebred Israeli Holstein cows with Norwegian Red semen, and 7487 purebred Israeli Holstein cows of the same age in the same 50 herds were analyzed for production, calving traits, fertility, calving diseases, body condition score, abortion rate and survival under intensive commercial management conditions. Holstein cows were higher than crossbreds for 305-day milk, fat and protein production. Differences were 764, 1244, 1231 for kg milk; 23.4, 37.4, 35.6 for kg fat, and 16.7, 29.8, 29.8 for kg protein; for parities 1 through 3. Differences for fat concentration were not significant; while crossbred cows were higher for protein concentration by 0.06% to 0.08%. Differences for somatic cells counts were not significant. Milk production persistency was higher for Holstein cows by 5, 8.3 and 8% in parities 1 through 3. Crossbred cows were higher for conception status by 3.1, 3.6 and 4.7% in parities 1 through 3. Rates of metritis for Holsteins were higher than the crossbred cows by 7.8, 4.6 and 3.4% in parities 1 to 3. Differences for incidence of abortion, dystocia, ketosis and milk fever were not significant. Holstein cows were lower than crossbred cows for body condition score for all three parities, with differences of 0.2 to 0.4 units. Contrary to comparisons in other countries, herd-life was higher for Holsteins by 79 days. A total of 6321 Holstein cows born between 2007 and 2011 were higher than 765 progeny of crossbred cows backcrossed to Israeli Holsteins of the same ages for milk, fat and protein production. Differences were 279, 537, 542 kg milk; 10.5, 17.7, 17.0 kg fat and 6.2, 12.9, 13.2 kg protein for parities 1 through 3. Differences for fat concentration were not significant, while backcross cows were higher for protein percentage by 0.02% to 0.04%. The differences for somatic cell score, conception rate, and calving diseases other than metritis, were not

    The introduction of acellular dermal matrices (ADMs) contributed to the growing diffusion of direct-to-implant breast reconstruction (DTI-BR) following mastectomy for breast cancer. According to specific legislations, European specialists could not benefit from the use of human-derived ADMs, even though most evidence in the literature are available for this kind of device, showed optimal outcomes in breast reconstruction. The Skin Bank of the Bufalini Hospital (Cesena, Italy) obtained in 2009 the approval for the production and distribution of a new human cadaver-donor-derived ADM (named with the Italian acronym, MODA, for matrice omologa dermica acellulata) from the Italian National Transplant Center and National Health Institute. We report preliminary results of MODA application in direct-to-implant breast reconstruction following nipple-areola complex (NAC)-sparing mastectomy for breast cancer treatment. We prospectively enrolled all women undergoing NAC-sparing mastectomy for breast cancer and DTI-BR in our breast surgical unit from June 2015 to January 2017. We enrolled a selected population without previous chest wall irradiation, not being heavy tobacco smokers or diabetic, with a BMI MODA in direct-to-implant breast reconstruction following NAC-sparing mastectomy for breast cancer treatment. This is particularly relevant for the European market, where no other human-derived devices are available for breast reconstruction due to regulatory restrictions.

    2007-01-01

    Full Text Available Abstract Background Artemisinin-derivative formulations are now widely used to treat falciparum malaria. However, the dry powder suspensions developed for children are few and/or are of poor quality. In addition to the active compound, the presence of a suitable preservative in these medicines is essential. In this study, an evaluation of the preservative content and efficacy in some dry suspensions available on the Kenyan market was performed. Method UV spectrophotometry was used to identify the preservatives in each sample while HPLC-UV was used for quantification. After reconstitution of the powders in water, the dissolution of the preservatives was followed for 7 days. Antimicrobial efficacy of the preservatives was assessed by conducting a preservative efficacy test (PET following the European pharmacopoeia standards. Results Four different preservatives were identified namely methylparahydroxybenzoate (MP, propylparahydroxybenzoate (PP, benzoic acid and sorbic acid. MP and PP were identified in Artesiane® (artemether 300 mg/100 ml, Alaxin® (dihydroartemisinin 160 mg/80 ml andGvither ® (artemether 300 mg/100 ml respectively. Sorbic acid was presentin Artenam® (artemether 180 mg/60 ml while benzoic acid was identified in Santecxin® (dihydroartemisinin 160 mg/80 ml andArtexin® (dihydroartemisinin 160 mg/80 ml respectively. Cotecxin® (dihydroartemisinin 160 mg/80 ml did not contain any of the above preservatives. After reconstitution in water, preservativesin 50%(3/6 of the products did not completely dissolve and the PET results revealed that only Artenam® and Gvither® met the requirements for antimicrobial efficacy. The other products did not conform. Conclusion These results show that paediatric antimalarial dry powder formulations on the market may contain ineffective or incorrect amounts of preservatives. This is a potential risk to the patient. Studies conducted on the dry powder suspensions should include the analysis of both

    Full Text Available Molting is a problem for duck farmers, during which the ducks stop laying eggs. Molting characteristics may be altered through crossing between non-molting to molting ducks. The purpose of this study was to evaluate molting characteristics of the crossing between Alabio and Pekin ducks. The materials used were 90 female AP (Alabio males x Pekin females and 90 female PA (Pekin males x Alabio females, 25 female Alabio and 25 female Pekin ducks. The ducks were housed in individual cages at the Indonesian Research Institute for Animal Production, Ciawi Bogor. Variables measured were the length of molting and egg production in 30 weeks, data were analyzed using ANOVA and followed by the estimation of the value of heterosis. Result showed that the molting of Pekin ducks was 71.31±9.36 days, it was longer than Alabio, AP or PA ducks, which were respectively 42.44±8.59, 43.63±4.88 and 49.35±4.85 days (P<0.01. Egg production of Pekin duck (56.41±4.59 was significantly lower (P<0.01 than that of Alabio, AP or PA, which were 72.48±3.24, 83.75±1.39 and 76.12±1.68 respectively. The heterosis of molting period of AP was higher than that of PA (-23.29 vs -13.23%. The heterosis of egg production of AP was higher than PA (29.96 vs 18.12%. It is concluded that the AP crossbred could be utilized as the initial population to produce a superior line characterized by high egg production and controllable molting.

    Full Text Available The aim of this study was to evaluate the effects of bovine leukemia virus (BLV infection on productive performance of dairy cattle in Brazil. A total of 158 blood samples from lactating adult cows, purebred Holstein and crossbred Holstein X Zebu, were analyzed by Agar Gel Immunodifusion Test (AGID and leukogram. According to AGID and leukogram results, animals were grouped into three categories: seronegative, seropositive without persistent lymphocytosis, and seropositive with persistent lymphocytosis. Milk production data were compared between groups, according to breed. BLV infected females showed lower milk yield than uninfected ones, both purebred and crossbred ones. There was no difference between milk yield of seropositive cows with or without persistent lymphocytosis. These results indicate an association between BLV infection and reduction of milk production, and this study is the first one to show these effects in crossbred Holstein X Zebu cows.

    To assess the refractive state of the equine eye utilizing retinoscopy. To compare the refractive state of Spanish Thoroughbred horses with the refractive state of Crossbred horses. The refractive state of 135 horses (264 eyes) was assessed utilizing streak retinoscopy. Two perpendicular meridians were examined in order to assess astigmatism at a working distance of approximately 67 cm. A group of 81 Spanish Thoroughbred horses was compared with a group of 54 Crossbred horses. Cyclopentolate ophthalmic solution was instilled in the eyes of a group of 18 horses to determine if accommodation has any influence on the assessment of the refractive state.   Mean ± SE refractive state of all horses examined was -0.17 ± 0.04 D. The mean refractive state of the Spanish Thoroughbred was -0.28 ± 0.06 D while that of the Crossbred was -0.01 ± 0.05 D. The refractive state of the Spanish Thoroughbred was found to be statistically different to that of the Crossbred. The most prevalent refractive state was emmetropia in all cases, followed by hyperopia for the Crossbred, and myopia for the Spanish Thoroughbred. Astigmatism ≥0.50 D present in both eyes from the same individual was found in 21.7% of all horses examined. Anisometropia ≥1.00 D was diagnosed in 4 out of 129 horses with both visual eyes. Cycloplegia did not statistically affect the refractive state of the evaluated eyes. The equine eye has a refractive state close to emmetropia. Myopia is higher among Spanish Thoroughbred horses than among Crossbred horses. © 2012 American College of Veterinary Ophthalmologists.

    Full Text Available Aim: The present study was undertaken in Holstein-Friesian (HF crossbred cattle with the objective to find out genotype of HF crossbred cattle for Bovine Leucocyte Adhesion Deficiency (BLAD by using PCR-RFLP. Materials and Methods: 50 blood samples were collected from HF crossbred cattle and subjected to PCR. The amplified PCR products were digested using Taq I restriction enzyme at 65 oC overnight. After restriction digestion, the final PCR products were electrophoresed on 2.5 % agarose gel. Results: All the 50 animals under present investigation were found to be normal as the amplified PCR product upon digestion with Taq I restriction enzyme, revealed two bands of 313 bp and 54 bp for normal animals. Conclusions: In the present investigation D128G carrier frequency was found to be 0 %. However, recent reports suggest that the mutant gene has already been observed in the HF crossbred cattle population of India, which makes it necessary to screen the animals to avoid the risk of spreading BLAD in the breeding cattle population.

    Full Text Available The present study was conducted on 412 crossbred (Jersey X Deshi cows sired by 24 bulls, maintained over the period from 2005 to 2014. The economic traits studied were age at first calving (AFC; months, calving interval (CI; days, dry period (DP; days and service period (SP; days. The averages for AFC, CI, DP and SP were 34.46±0.22 months, 505.95±3.24, 224.20±3.31 and 228.26±3.21 days, respectively. Effect of management system was significant for all the economic traits (AFC, CI and DP except SP. It may be inferred that rearing crossbred Jersey cows under intensive system of management may be advocated to utilize the maximum genetic potential of crossbred cattle for all the traits. Semi-intensive system may help moderate exploration of the traits. But exclusively pasture dependent management should be avoided for rearing crossbred Jersey cows. Heritability estimates for AFC, CI and DP were found to be 0.462 ±0.179; 0.062 ±0.088; 0.270 ±0.138, respectively. Genetic correlations of AFC with CI and SP were high and positive. For maximum genetic improvement and their correlated response, it is necessary to include all the economic traits with differential weightage for achieving accuracy in selection programs.

    Wild boars, because of their large size and ability to survive adverse conditions, are usually used to cross with domestic breeds to improve the quality of domesticated pigs. This study aimed to investigate the growth performance, slaughter performance, and meat quality of Ziwuling crossbred pigs. Crossbred pigs in four groups (n = 8 per group, 4 boars and 4 sows, all aged 100 days), F 1 [wild × B (Bamei)], F 1  × B, F 1  × Y (Yorkshire), and F 1  × F 1 , were selected at a commercial pig farm. Growth performance, slaughter performance, and meat quality of these crossbred pigs were determined. Characteristics of fatty acids, amino acids, and longissimus muscle fiber in relation to growth, carcass, and meat quality traits were also investigated. Pigs in F 1 and F 1  × F 1 groups had lower average daily weight gain, water and storage loss rates, larger meat color score, higher muscle amino acid levels, larger muscle fiber diameter, and higher ratio of flavor amino acids to unsaturated fatty acids compared to other groups. Crossbred pigs with higher rate of wild boar's consanguinity could improve production performance, slaughter performance, and meat quality. Thus, crossbreeding wild pig with domestic breeds might be an effective method to improve meat quality and flavor.

    Natural lambing in sheep in Ethiopia occurs throughout the year in a scattered manner negatively affecting survival and growth rates of the lambs born during the unfavorable season of the year. Thus, controlling the time of mating artificially using exogenous source of hormones is considered as one of the ways to mitigated problems related to haphazard lambing. To this end, an experiment was conducted to evaluate efficacy of prostaglandin-based estrus synchronization protocol in local and crossbred ewes. A total of 160 ewes (80 local and 80 crossbreds) which lambed at least once and aged 3-5 years were used. Lutalyse® (dinoprost tromethamine sterile solution equivalent to 5 mg dinoprost per ml) and its analog, Synchromate® (cloprostenol sodium equivalent to 0.250 mg cloprostenol per ml), were tested at different doses. The treatments used were intramuscular injection of (1) 2.50 ml of Lutalyse® (12.5 mg dinoprost tromethamine), (2) 2 ml of Lutalyse® (10.0 mg dinoprost tromethamine), (3) 1 ml of Synchromate® (0.25 mg of cloprostenol Sodium), and (4) 0.8 ml of Synchromate® (0.20 mg of cloprostenol Sodium). Forty ewes (20 local and 20 crossbreds) were allocated per treatment. Following injection of the respective hormones, rams of known fertility were introduced into the flock for the duration of 96 h at the ratio of one ram to 10 ewes. All estrus synchronization protocols except treatment 4 (0.8 ml of Synchromate®) induced estrus (heat) in majority (55-65%) of local and crossbred ewes within 96 h post-hormone injection. The time interval from hormone administration to onset of estrus was also more or less similar for all treatment groups except for treatment group 4 which showed heat quicker. The highest lambing rate was recorded in local ewes (84.62% (11/13) treated with 2.5 ml of Lutalyse®, whereas the least was obtained in crossbreds (33.33% (3/9) treated with 0.8 ml Synchromate®. In conclusion, even though 2.5 ml and 2 ml of Lutalyse® or 1 ml of

    Crossbreed dairy breeds, such as Holstein × dairy type of Simmental, have been generally used to improve fertility, udder health, and longevity of dairy herds. The aim was to compare the reproductive performance and survival of Holstein and Holstein × Simmental crossbred cows. Data from two farms were used as follows: one located in Bom Retiro, in the state of Santa Catarina, Brazil. and another in Carambeí, Paraná state. Information concerning birth, inseminations, and parity date were obtained from the management software of the farms, generating information regarding the calving interval, days between calving to first service, conception rate, and age at first calving. At one of the farms, calving was monitoring to quantify dystocia. Live weight as well as body condition score (BCS) of cows and information of culling were obtained to determine the survival rate. Data were analyzed by variance analysis and by logistic regression. Crossbred Holstein × Simmental cows had better reproductive performance than the Holstein cows, characterized by lower calving interval (381 vs. 445 days), higher conception rate (37.3 vs. 33.6 %), and shorter calving to first service interval (65 vs. 89 days). These results were related to a higher BCS in crossbred cows (3.63 vs. 2.94 points). Crossbred Holstein × Simmental cows had higher survival rate than Holstein cows on the second parity (83 vs. 92 %). No differences between genetic groups were observed (P > 0.05) for body weight and dystocia. In conclusion, Holstein × Simmental crossbred cows have better reproductive performance and higher survival rate than Holstein cows.

    2014-09-01

    Full Text Available Research has shown that violations of put-call parity do occur and that these violations present an investor with opportunities to profit from arbitrage deals. Mispricing may lead to significant superior returns and maximisation of shareholders’ wealth if found and acted upon in a timely manner. This study attempts to determine whether this mispricing of financial derivatives is present in the South African derivatives market. This will be achieved through the valuation of options on single stock futures using the put-call parity relationship. The theoretical fair values obtained, is compared to the actual market values over a period of three years, that is, from 2009 to 2011. The results show that arbitrage opportunities do present themselves for the chosen shares. Further research may involve more shares over a longer period to determine whether any pattern may exist which may form the basis of an arbitrage trading strategy

    2009-08-01

    Non-steroidal and tissue-selective anabolic agents such as selective androgen receptor modulators (SARMs) represent a promising class of therapeutics for the treatment of various diseases such as sarcopenia or cancer cachexia. Advanced compounds of SARMs are based on an arylpropionamide-derived structure and leading drug candidates have successfully completed phase-II-clinical trials. Although none of these therapeutics have been approved, their performance-enhancing qualities and the black-market availability of these products makes them a viable target for misuse in the athletic community. In 2008, SARMs were added to the Prohibited List established by the World Anti-Doping Agency (WADA). That SARMs are the subject of misuse even without clinical approval was proved for the first time by the detection of the drug candidate Andarine (also referred to as S-4, S-3-(4-acetylamino-phenoxy)-2-hydroxy-2-methyl-N-(4-nitro-3-trifluoromethyl-phenyl)-propionamide), advertised, sold and supplied via the Internet. The oily liquids, declared as green tea extracts and face moisturizer, were assayed using state-of-the-art analytical procedures and S-4 was found at concentrations of approximately 150 mg/mL. The authenticity of the product was demonstrated in comparison to reference material by liquid chromatography, high resolution/high accuracy (tandem) mass spectrometry using positive and negative electrospray ionization, and comparison to reference material. Moreover, an impurity resulting from poor product purification was detected, accounting for approximately 10% of S-4. This consisted of 2-hydroxy-2-methyl-N-(4-nitro-3-trifluoromethyl-phenyl)-3-(4-nitro-3-trifluoromethyl-phenylamino)-propionamide. The ease of purchasing non-approved drug candidates that could potentially increase athletic performance demonstrates the need to operate proactively in the continued fight against doping. The early inclusion of emerging drugs into routine sports drug testing procedures is a key

    2015-01-01

    This paper presents a framework for optimally allocating storage technologies in a power system. This decision support tool helps in quantitatively answering the questions on “where to and how much to install” considering the profits from arbitrage opportunities in a co-optimized electricity market. The developed framework is illustrated on a modified IEEE (Institute of Electrical and Electronics Engineers) 24 bus RTS (Reliability Test System), and the framework finds the optimal allocation solution and the revenues storage earns at each of these locations. Bulk energy storage, CAES (compressed air energy storage) is used as the representative storage technology, and the benefits of optimally allocated storage integration onto the grid are compared with transmission expansion solution. The paper also discusses about system-level indicators to identify candidate locations for economical storage ventures, which are derived based on the optimal storage allocation solution; and applies the market price based storage venture indicators on MISO (Mid-continental Independent System Operator) and PJM (Pennsylvania-New Jersey-Maryland Interconnection) electricity markets. - Highlights: • Storage optimal allocation framework based on high-fidelity storage dispatch model. • Storage with transmission addresses energy and ancillary issues under high renewables. • Bulk storage earns higher revenues from co-optimization (∼10× energy only market). • Grid offers distributed opportunities for investing in a strategic mix of storage. • Storage opportunities depend on cross-arbitrage, as seen from MISO (Mid-continental Independent System Operator) and PJM (Pennsylvania-New Jersey-Maryland Interconnection) markets

    Full Text Available In this work, linear body measures were taken and production indices calculated for 100 Cuban Creole goats and 100 crossbred goats in order to aid in the characterization of animal genetic resources in Cuba. Low variation was found for all indices of the Creole goats, showing homogeneity between the groups of animals studied. Most of the functional indices are related to the milk biotype which is in agreement the possible origin of the breed from animals of the Iberian Peninsula and Canary Islands. The crossbreds were more varied, mostly due to undesigned disorganized crossing. These data may help in identifying a commercial niche for the breed and contribute to in situ conservation of the Cuban Creole goat.

    Full Text Available The objective of this study was to identify claw lesions causing clinical lameness in lactating Holstein Frisian (HF crossbred cows in dairy cattle. Seventy dairy farmers were interviewed at the monthly meetings of Progressive Dairy Farmers Association of Ludhiana, Punjab, India. Ten dairy farms were randomly selected as per probability proportional to size and a total of 450 lactating HF crossbred cows were taken into the study. All the lactating cows were scored for locomotion and rear leg view index. Trimming was done in all the clinically lame animals (animals with locomotion scores 2 and 3 and equal number of animals selected randomly from those with locomotion scores 0 and 1. Various claw lesions were evaluated in both the groups. There was a significant relationship between locomotion score and rear leg view index to identify lameness. Sole ulcers and white line fissures were the lesions responsible for clinical lameness. Other lesions did not cause clinical lameness but increased the asymmetry in lactating HF crossbred cows. Both locomotion score and rear leg view index could be reliably used to identify clinical lameness in lactating cattle.

    This aim of this study was to determine the quality of nutritional contents of beef brisket point end of Simental Ongole Crossbred meat in various boiling temperatures. Simental Ongole Crossbred had been fattened for 9 months. Furthermore, they were slaughtered at slaughterhouse and brisket point end part of meat had been prepared to analyse its nutritional contents using Food Scan. These samples were then boiled at 100°C for 0 (TR), 15 (R15), and 30 (R30) minutes, respectively. The data was analysed using Randomized Complete Design (CRD) and Duncan’s multiple range test (DMRT) had been conducted to differentiate among three treatments. The results showed that boiling temperatures significantly affected moisture, and cholesterol contents of beef (P<0.05) while fat content was not significantly affected by boiling temperatures. The boiling temperature decreased beef water contents from 72.77 to 70.84%, on the other hand, the treatment increased beef protein and cholesterol contents from 20.77 to 25.14% and 47.55 to 50.45 mg/100g samples, respectively. The conclusion of this study was boiling of beef at 100°C for 15 minutes and 30 minutes decreasing water content and increasing protein and cholesterol contents of brisket point end of Simental Ongole Crossbred beef.

    Many local livestock breeds in developing countries are being replaced by exotic breeds, leading to a loss of genetic resources. In southern Mali, for the past two decades, a trend towards increasing crossbreeding between the trypanotolerant N'Dama cattle and the trypano-susceptible Fulani Zebu cattle has been taking place. A survey with 160 farmers owning a cattle herd was carried out in southern Mali to investigate their production objectives, as well as trait and breed preferences and correlated socio-economic determinants in order to understand farmers' breeding decisions and to identify comparative advantages of three breed groups (N'Dama, Fulani Zebu and crossbreds) raised in the study area. Data were analyzed using an exploded logit model. The reasons for raising cattle, as well as trait and breed preferences reflected the multiple objectives of the farmers. Draught power and savings were the most important production objectives. Productive traits were ranked highest; farmers reported large body size as the most preferred trait, followed by fertility, draught ability and milk yield. Crossbreds were the favored breed group. Breed preferences were mainly explained by 'resistance to disease' for N'Dama cattle and 'high market price' for Fulani Zebu and crossbred cattle. Production objectives, trait and breed preferences were mainly influenced by farmer group (local farmers and settled transhumants). Local farmers put comparatively more emphasis on livestock functions linked to crop production such as draught power. They had a higher preference for traction ability as a selection trait and preferred N'Dama over Fulani Zebu cattle. Settled transhumants emphasized milk yield as a selection trait and preferred Fulani Zebu over N'Dama. The results indicate that the trend towards more crossbreeding will continue putting the N'Dama breed under high risk of genetic dilution in southern Mali. The N'Dama cattle remain a valuable breed due to their adaptive traits such as

    Full Text Available Cutaneous evaporative heat loss in Bos indicus and Bos taurus has been well documented. Nonetheless, how crossbreds with different fractional genetic proportions respond to such circumstances is of interest. A study to examine the physiological responses to cutaneous evaporative heat loss, also lactation period and milk yield, were conducted in Sahiwal (Bos indicus, n = 10, 444±64.8 kg, 9±2.9 years, Holstein Friesian (Bos taurus, HF100% (n = 10, 488±97.9 kg, 6±2.8 years and the following crossbreds: HF50% (n = 10, 355±40.7 kg, 2±0 years and HF87.5% (n = 10, 489±76.8 kg, 7±1.8 years. They were allocated so as to determine the physiological responses of sweating rate (SR, respiration rate (RR, rectal temperature (RT, and skin temperature (ST with and without hair from 06:00 h am to 15:00 h pm. And milk yield during 180 days were collected at days from 30 to 180. The ambient temperature-humidity-index (THI increased from less than 80 in the early morning to more than 90 in the late afternoon. The interaction of THI and breed were highly affected on SR, RR, RT, and ST (p0.05 but did change over time. The ST with and without hair were similar, and was higher in HF100% (37.4°C; 38.0°C and their crossbred HF50% (35.5°C; 35.5°C and HF87.5% (37.1°C; 37.9°C than Sahiwal (34.8°C; 34.8°C (p<0.01. Moreover, the early lactation were higher at HF100% (25 kg and 87.5% (25 kg than HF50% (23 kg which were higher than Sahiwal (18 kg while the peak period of lactation was higher at HF100% (35 kg than crossbreds both HF87.5% and HF50% (32 kg which was higher than Sahiwal (26 kg (p<0.05. In conclusion, sweating and respiration were the main vehicle for dissipating excess body heat for Sahiwal, HF and crossbreds, respectively. The THI at 76 to 80 were the critical points where the physiological responses to elevated temperature displayed change.

    The legendary Vechur cattle of Kerala, described as a very short breed, and the crossbred (CB) Sunandini cattle population exhibited great phenotypic variation; hence, the present study attempted to analyze the genetic diversity existing between them. A set of 14 polymorphic microsatellites were chosen from FAO-ISAG panel and amplified from genomic DNA isolated from blood samples of 30 Vechur and 64 unrelated crossbred cattle, using fluorescent labeled primers. Both populations revealed high genetic diversity as evidenced from high observed number of alleles, Polymorphic Information Content and expected heterozygosity. Observed heterozygosity was lesser (0.699) than expected (0.752) in Vechur population which was further supported by positive F IS value of 0.1149, indicating slight level of inbreeding in Vechur population. Overall, F ST value was 0.065, which means genetic differentiation between crossbred and Vechur population was 6.5%, indicating that the crossbred cattle must have differentiated into a definite population that is different from the indigenous Vechur cows. Structure analysis indicated that the two populations showed distinct differences, with two underlying clusters. The present study supports the separation between Taurine and Zebu cattle and throws light onto the genetic diversity and relationship between native Vechur and crossbred cattle populations in Kerala state.

    Full Text Available The objectives of this study were to detect the Mendelian mode inheritance of growth hormone (GH and to establish genotype frequency of GH gene in Ongole-crossbred cattle mated by the artificial insemination (AI technique. Total of 76 blood samples were collected from Ongole-crossbred cows and bulls (G0, and their progenies (G1 at the Tumaratas AI service center in North Sulawesi province, Indonesia. All blood samples were screened for the presence of GH locus using a PCR-RFLP method involving restricted enzyme Msp1 on 1.2 % of agarose gel. Data were analyzed using statistical program function in Excel XP. The results showed that GH locus using alleles of Msp1+ and Msp1- enzyme restriction in Ongole-crossbred cows and bulls was inherited to their Ongole-crossbred progenies following the Mendelian mode inheritance. This Mendelian inheritance generated by AI technique was not under genetic equilibrium for the Msp1 genotype frequencies in groups of G0 and G1. The breeding program using genotypes of bulls and cows (G0 for generating the genotype of GH Msp1 enzyme restriction by AI technique should be maintained to increase these various allele dispersion rates for breeding under genetic equilibrium of the Ongole-crossbred cattle population.

Nine “Fumati” crossbreds (Large White x Mora Romagnola; average initial live weight: 84 kg and nine “Borghigiana” (Large White x Nera di Parma; average initial live weight: 90 kg, reared under similar environmental and nutritional conditions, were slaughtered at the average final weight of 180 kg (285 days. Calculated dry matter intake (DMI and feed conversion index (FCI were similar; no significant differences were observed with respect to average daily gain (ADG: 679 vs. 658 g/d. At slaughtering, the dressing percentage of the Fumati was significantly lower than that of the Borghigiana (80.9 vs. 84.5. The Fumati seemed more prone to fattening than the Borghigiana, as confirmed by the statistically higher percentage of belly (14.9 vs.12.2, and fat (3.9 vs. 2.4 and marbling of M. longissimus dorsi (2.7 vs. 1.4. On colour analysis, the Fumati had statistically higher L* and hue values, and lower a* of M. longissimus dorsi. The fatty acid composition of meat was similar between crossbreds; backfat fatty acid composition of the Fumati showed a significantly higher percentage of saturated fatty acids (SFA, and lower amounts of monounsaturated and polyunsaturated fatty acids (MUFA and PUFA than in the Borghigiana. Results showed that performances and meat quality of local crossbreeds still bred in semi-intensive systems, like Fumati and Borghigiana, can be positively influenced when fed diets considered suitable for improved pig genotypes.

    The Bashang Long-tail chicken (BS), an indigenous Chinese breed, is considered cold tolerant. We selected BS, the Rhode Island Red (RIR), and their reciprocal crossbreds for the present study. The objectives were: i) to validate whether BS is cold tolerant and whether egg production and cold tolerance of crossbreds could be improved; and ii) to determine the physiological characteristics that underlie cold tolerance and favorable egg production performance in cold environments. A total of 916 chickens were reared in warm and natural cold environments (daily mean ambient temperature varied from 7.4°C to 26.5°C in the warm environment and from -17.5°C to 27.0°C in the cold environment). To investigate their adaptability to the cold environment, the egg production performance and body weight were monitored and compared between breeds and environments. The cloacal temperature and serum biochemical parameters were monitored to reveal the physiological characteristics underlie cold tolerance and favorable egg production performance in the cold environment. The warm environment experiment showed that RIR had the highest egg production performance, and that the reciprocal crossbreds had a higher egg production performance than BS. While in the cold environment RIR had the lowest egg production performance, and the reciprocal crossbreds had a higher egg production performance than BS. In the cold environment BS and reciprocal crossbreds had higher triiodothyronine, tetraiodothyronine levels than RIR. At 35 and 39 wk of age, when the ambient temperature was extremely low (varied from -20°C to 0°C), serum glucose, follicle-stimulating hormone, luteinizing hormone, estradiol of BS and crossbreds were higher than RIR. Bashang Long-tail chicken has a favorable cold tolerance ability. Crossbreeding with RIR and BS is an effective way to develop cold tolerant chickens with improved egg production performance.

    Full Text Available [b]Introduction[/b]. Treatment with fixed orthodontic appliances requires the application of adhesive systems to enable secure fastening of brackets and retainers to the surface of tooth enamel. The orthodontic bonding systems are similar in terms of chemical composition to dental filling materials, the chemical stability of which is not satisfactory. Particularly alarming is the release of bisphenol A and its derivatives to the external environment, which has been well-documented for materials used in conservative dentistry. [b]Objectives[/b]. The aim of the study was an in vitro assessment of the release of biologically harmful bisphenol A and its derivatives from orthodontic adhesives available on the European market, as a potential health risk factor for orthodontic patients. [b]Material and methods[/b]. The study assessed levels of BPA, BPA polymers and Bis-GMA resin in eluates of six commonly used orthodontic adhesives: Light Bond, Transbond XT, Resilence, Aspire, GrĕnGloo and ConTec LC, obtained after one hour, 24 hours, 7 days and 31 days of material sample storage in water. The presence and concentration of the studied chemicals in the obtained solutions were identified using the HPLC method. [b]Results[/b]. The highest (p≤0.05 concentration of BPA at 32.10µg/ml was observed in the Resilence material eluates. The highest concentration of poly-bisphenol A was found in solutions obtained after incubation of ConTec LC adhesive at 371.90µg/ml, whereas the highest amount of Bis-GMA resin (425.07µg/ml was present in Aspire material eluates. [b]Conclusions[/b]. 1 In conditions of the current experiment it was demonstrated that most of the assessed orthodontic adhesive resins available on the European market and released into the outside environment – biologically harmful bisphenol A or its derivatives, posing a potential threat to the patients’ health. 2 Release of BPA and its derivatives into aqueous solutions is the highest in the

    Bisphenol A (BPA), bisphenol A diglycidyl ether (BADGE), and their derivatives in 38 canned foods sold in Japan were measured using high-performance liquid chromatography-mass spectrometry (LC-MS) and LC-tandem mass spectrometry (LC-MS/MS). BPA, BADGE, BADGE.2H 2O, BADGE.HCl.H2O, BADGE.HCl, and BADGE.2HCl were 0-235.4, 0-3.4, 0-247.2, 0.2-196.4, 0-3.0, and 0-25.7 ng/g, respectively, which did not exceed acceptable daily intake for BPA and specific migration limit for BADGEs. BADGE was degraded by 58, 100, 46, and 58% in water (pH 7), 0.01 N HCl (pH 2), 0.01 N NaCl (pH 6.8), and 0.01 N NaCl with acetic acid (pH 2.5), respectively, when it was allowed to stand at 120 degrees C for 30 min. The prominent derivatives formed were BADGE.2H 2O and BADGE.HCl.H2O, which was formed not only in BADGE with added HCl but also in that with NaCl. Acetic acid accelerated the formation of both BADGE.2H2O and BADGE.HCl.H2O in NaCl. No BPA was detected in any simulation samples started from BADGE. The results suggest that BPA and BADGE are independently leached into canned foods and that BADGE is easily changed to more stable compounds such as BADGE.2H2O and BADGE.HCl.H2O by sterilization.

    Full Text Available This study attempts to determine whether mispricing of options on single stock futures is present in the South African derivatives market. The valuation of options on single stock futures is considered through the put-call parity relationship. The theoretical fair values obtained, are compared to the actual market values over a period of three years, that is, from 2009 to 2011. Only put options are considered in this research.The results show that arbitrage put option opportunities do present themselves for the chosen shares. The actual put options were found to be underpriced in 5 out of 6 (83% of the cases considered over the evaluation periods chosen. The mispricing was significant for both the BHP Billiton options with 100% and in the case of Sasol options (66% of the time. Whether profitable arbitrage opportunities is possible, will depend on the magnitude of the mispricing and the transaction fees payable. Further, more extensive research may help identify tendencies which may be of use for the formulation of arbitrage strategies

    Full Text Available Data pertaining to 11728 test-day daily milk yields of normal and mastitis Karan Fries cows were collected from the institute herd and divided as mastitis and nonmastitis and parity-wise. The data of lactation curves of the normal and mastitis crossbred cows was analyzed using gamma type function. FTDMY in normal and mastitis cows showed an increasing trend from TD-1 to TD-4 and a gradual decrease (P<0.01 thereafter until the end of lactation (TD-21 in different parities. The FTDMY was maximum (peak yield in the fourth parity. Parity-wise lactation curve revealed a decrease in persistency, steeper decline in descending slope (c, and steeper increase in ascending slope (b from 1st to 5th and above parity. The higher coefficient of determination (R2 and lower root mean square error (RMSE indicated goodness and accuracy of the model for the prediction of milk prediction performance under field conditions. Clinical mastitis resulted in a significantly higher loss of milk yield (P<0.05. The FTDMY was maximum (P<0.05 in the fourth parity in comparison to the rest of parity. It is demonstrated that gamma type function can give the best fit lactation curve in normal and mastitis infected crossbred cows.

    Full Text Available Abstract Background The modelling of lactation curve provides guidelines in formulating farm managerial practices in dairy cows. The aim of the present study was to determine the suitable non-linear model which most accurately fitted to lactation curves of five lactations in 134 Gir crossbred cows reared in Research-Cum-Development Project (RCDP on Cattle farm, MPKV (Maharashtra. Four models viz. gamma-type function, quadratic model, mixed log function and Wilmink model were fitted to each lactation separately and then compared on the basis of goodness of fit measures viz. adjusted R2, root mean square error (RMSE, Akaike’s Informaion Criteria (AIC and Bayesian Information Criteria (BIC. Results In general, highest milk yield was observed in fourth lactation whereas it was lowest in first lactation. Among the models investigated, mixed log function and gamma-type function provided best fit of the lactation curve of first and remaining lactations, respectively. Quadratic model gave least fit to lactation curve in almost all lactations. Peak yield was observed as highest and lowest in fourth and first lactation, respectively. Further, first lactation showed highest persistency but relatively higher time to achieve peak yield than other lactations. Conclusion Lactation curve modelling using gamma-type function may be helpful to setting the management strategies at farm level, however, modelling must be optimized regularly before implementing them to enhance productivity in Gir crossbred cows.

    Full Text Available Omasal impaction is a serious disease problem in cattle in India, but it is difficult to diagnose clinically. Ultrasonography has been proposed for the noninvasive evaluation of omasal disease. The objectives of this study were to compare the in vitro and in vivo ultrasonographic appearance of the omasum and to compare omasal appearance, limits, and size in clinically healthy cows with those in cows having confirmed omasal impaction. A 3.5 MHz curvilinear transducer was used to image and record the appearance of the omasum in vitro in a water bath, and its appearance, dorsal and ventral limits, and size in 10 healthy Indian Jersey/Red Sindhi crossbred cows. The results were compared with the ultrasonographic data collected from 5 cows with omasal impaction, as confirmed at necropsy. On moving the transducer dorsoventrally in each intercostal space and below the costal arch, the wall of omasum could be seen as an echogenic arc-like structure. The difference between mean dorsoventral extents of the normal and impacted omasums was statistically insignificant. These results suggest that ultrasonographic imaging may not be useful in the diagnosis of omasal impaction in Indian crossbred cows, however, additional studies may be warranted.

    Full Text Available A total of 2001 unsexed day-old-chicks of each Fayoumi, Rhode Island Red (RIR, RIR × Fayoumi (RIFI and Fayoumi × RIR (FIRI were obtained from hatchery of Poultry Research Institute, Rawalpindi. The birds were maintained on deep litter system for a period of 20 weeks. The results revealed that the average day old weight was highest in RIR and FIRI, intermediate in RIFI and lowest in Fayoumi chickens. The RIR breed consumed more feed and gained maximum (P0.05 difference among pure and crossbred chickens. There was non-significant (P>0.05 difference in haematological values among all chickens. The total erythrocyte number, haemoglobin and packed cell volume increased with the advancement of age. However, erythrocyte sedimentation rate, mean corpuscular volume and mean corpuscular haemoglobin values decreased gradually with the advancement of age. It may be concluded that crossbred chickens gained better body weight than Fayoumi and moderate than RIR chickens with lower mortality. The crossbred chickens of FIRI showed better performance in all traits than crossbred chickens of RIFI.

    Objectives of the current experiment were to evaluate plasma concentrations of metabolites and haptoglobin peripartum, uterine health and involution, and follicle growth and resumption of cyclicity of Holstein (HO) and Montbéliarde-sired crossbred cows. Cows (52 HO and 52 crossbred) were enrolled in the study 45 d before expected calving date. Cows had body weight and body condition score recorded on d -45, -14, 0, 1, 28, and 56 relative to calving. Dry matter intake was calculated for a subgroup of cows (25 HO and 38 crossbred) from 6 wk before to 6 wk after calving. Blood was sampled weekly from d -14 to 56 relative to calving for determination of glucose, nonesterified fatty acid, and β-hydroxybutyrate concentrations; from d -7 to 21 relative to calving for determination of haptoglobin concentration; and from d 14 to 56 postpartum for determination of progesterone concentration. Cows were examined at calving and on d 4, 7, 10, and 14 postpartum for diagnosis of postparturient diseases, on d 24 postpartum for diagnosis of purulent vaginal discharge, and on d 42 postpartum for diagnosis of subclinical endometritis. Uteri and ovaries were examined by ultrasonography every 3 d from d 14 to 41 postpartum. Milk yield and composition were measured monthly and yield of milk, fat, protein, and energy-corrected milk were recorded for the first 90 d postpartum. Body weight was not different between Holstein and crossbred cows, but HO cows had reduced body condition score compared with crossbred cows. Even though DMI from 6 wk before to 6 wk after calving tended to be greater for HO cows (16.8 ± 0.7 vs. 15.3 ± 0.5 kg/d), HO cows tended to have more pronounced decline in dry matter intake, expressed in percentage of body weight from d -15 to 0 relative to calving. Energy-corrected milk and nonesterified fatty acid and β-hydroxybutyrate concentrations were not different between breeds. No differences were observed in incidence of retained fetal membranes, metritis, and

    Full Text Available The objective of the present study was to evaluate the effect of four water salinity levels on the ingestive behavior of non-castrated crossbred Santa Inês sheep. Thirty-two non-castrated crossbred Santa Inês sheep in feedlot, at seven months of age and initial average weight of 21.76±1.25 kg, were used in the experiment. The experimental design was completely randomized, with four treatments and eight replicates. Four concentrations of salts in the water fed to the animals were evaluated: low (640 mg/l; medium (3,188 mg/l; high (5,740 mg/l and very high (8,326 mg/l levels of total dissolved solids (TDS. For the ingestive behaviors, the animals were observed every ten minutes, for 24 hours, to determine the time spent feeding, ruminating and idle. Also, cud chewing and the average number of defecations and urinations and the frequency of water ingestion were determined. The time spent feeding, ruminating and idle were not changed by the salinity levels in the water. Dry matter intake, neutral detergent fiber intake, total chewing time, total cud chews per day, number of daily meals, average duration of each meal and number of defecations per day did not change either. However, feeding and rumination efficiency in grams of DM/h, water intake and number of urinations were linearly affected, whereas the variables rumination efficiency in grams of NDF/h, grams of dry matter per cud, grams of neutral detergent fiber per cud, number of cuds, number of chews per cud and chewing time per cud presented quadratic effect. The different levels of total dissolved solids (640; 3,188; 5,740; and 8.326 mg/l in the water fed to the sheep did not cause alterations in their ingestive behavior. In conclusion, water with up to 8,326 mg TDS/l can be an alternative strategic and seasonal method to water crossbred Santa Ines sheep.

    Full Text Available Pigs of two crosses: A (Duroc x Swedish Landrace x Pietrain (n=24 and B (Swedish Landrace x Large White x Pietrain (n=26 were used to investigate the effects of different lairage time (2 and 24 hours on levels of stress and meat quality traits. No direct effect of lairage time on cortisol, lactate, electrolytes and meat quality parameters was observed. However, after long lairage time, pigs showed lower level of glucose and higher CK, AST and ALT activity. Crossbred B pigs exposed to short lairage time, showed higher blood lactate, sodium, and potassium level, higher drip loss and lower pHi, whereas there were no significant differences between the crossbreeds in the long lairage group. The results indicate that long lairage time decreases blood glucose level and produces signs of muscle damage. In the short lairage period, the crossbreed B showed a higher response to pre-slaughter handling affecting the meat quality.

    The purpose of this study was to investigate the importance and the effect of shading and non-shading house on physiological changes, body weight (BW), average daily gain (ADG), total antioxidant and thyroid hormones in crossbred calves under hot conditions. Thirty six growing crossbred calves (Friesian x Baladi) aged 8-10 months were divided into two groups (each 18 calves); the first group was maintained in shaded house and the second in house without shade (climatic house). The period of study was 79 days during hot conditions. Performance variables (BW, ADG) were measured and the blood samples were collected to assess some biochemical parameters including antioxidants such as total antioxidant (TA), catalase (CAT), total protein, thyroid hormones (T3, T4) and immunoglobulin factor (IgG). Respiration rates and behaviour parameters (feeding, drinking, standing, lying and agonistic) were also measured during the study. The data indicated that the shaded calves had higher ADG (P<0.05) and final BW than non-shaded ones. Also, a significant improvement in total protein levels and globulins were recorded in shaded house calves as compared to non-shaded ones. The same result was obtained for T3 level whereas non-significant changes were observed for T4 level as well as the level of IgG at different times. The present data indicated that using shaded house will decrease the effect of heat stress on calves which will increase the animal performance through improving BW and ADG as well as some biochemical parameters in addition to T3 hormonal level.

    Full Text Available Aim: The objective of this study was to investigate the effect of genetic and non-genetic factors and estimate the genetic parameter for gestation length (GL of Jersey crossbred cattle. Materials and Methods: The data included the 986 parturition records on Jersey crossbred cattle maintained at the Eastern Regional Station of ICAR-National Dairy Research Institute, Kalyani, West Bengal, India during 36 years (1978-2013. The data were analyzed applying mixed model least square technique considering the fixed effects of genetic group, season of calving, period of calving, parity of animal, birth weight, and sex of calf born from animal. The effect of sire was included as a random effect in the model. Results: The genetic group of animal, season of calving, parity of animal, and birth weight of calf born were found to be a significant source of variation in the GL, whereas the period of calving and sex of calf did not affect this trait. Cows with 62.5% Jersey inheritance had the shortest and longest GLs, respectively. Cows calved in summer and rainy season had shorter GL than those calved in the winter season. Older cows in 4th parity carried calves for longer days than the cows in 1st parity. The increase in calf birth weight significantly (p<0.01 contributed to a linear increase in GL value in this study. The heritability estimate of GL was 0.24±0.08. Conclusion: It can be concluded that selection for lower GL without distressing future growth of calf can be used to reduce calving difficulty, but a very small standard deviation of GL limits the benefit. Moreover, more accurate prediction of calving date will help in better management and health care of pregnant animals.

    According to the seasonal variations in environmental conditions in post-partum cows, some biochemical and physiological changes which affect the productive efficiency of farm animals may occur. This study was conducted in the bovine farm of Experimental Farms Project of Nuclear Research Centre, Atomic Energy Authority, Inshas, Egypt, to evaluate some blood biochemical and some hormonal changes during the suckling period in crossbred cows under winter and summer conditions. Alterations in metabolites and metabolic hormones during the first 10 weeks post-partum in both winter and summer during a period of suckling were analyzed on a total of 13 crossbred (Brown Swiss X Balady) cows (winter, n=7; summer, n=6). The blood samples were taken at 2 weeks intervals, 5 times in each season to determine the concentrations and changes in glucose, urea, total cholesterol, total proteins and some hormones including leptin, T4 and progesterone (P4) under winter and summer conditions. The data indicated that total protein (P<0.01), glucose (P<0.05), leptin (P<0.01), total cholesterol (P<0.01), and T4 (P<0.01) had significant seasonal differences between the two calving groups. A positive correlation coefficient was observed between leptin and T4 hormone. From the obtained data, it could be concluded that in summer season, certain biochemical and hormonal levels of calving cows may enhanced but not enough to affect the levels of urea and progesterone. The positive correlation between leptin and T4 may indicate association in the rate of metabolism.

    Heat stress is an important domain of research in livestock due to its negative impact on production and disease resistance. The augmentation of stress in the body stimulates the antioxidative activity comprising various enzymes (viz., catalase, superoxide dismutase), metabolites (reduced glutathione, etc.), vitamins, minerals, etc. to combat the situation. The major key players involved in regulation of heat shock response in eukaryotes are the transcription factors, called as heat shock factors (HSF). They activate the heat shock protein (HSP) genes by binding to their promoters. Lymphocytes are considered to be the best model to evaluate the immunity in any living body as it contains plethora of white blood cells (WBCs).In this study, the peripheral blood mononuclear cells (PBMC) obtained from non-lactating Sahiwal vis-à-vis crossbred (Holstein Friesian × Sahiwal) cattle with 75% or more exotic inheritance were subjected to heat shock at 39, 41, and 43 °C in three different incubators, in vitro. The cell count and viability test of pre and post heat stress of concerned PBMCs indicated that the crossbreeds are more prone to heat stress as compared to Sahiwal. The reverse transcription PCR (qRT-PCR) expression data revealed an increment in HSF1 expression at 41 °C which subsequently declined (non-significantly) at 43 °C in both breeds post 1 h heat shock. However, the association between the HSF 1 expression and antioxidative activity through correlation analysis was found to be non-significant ( P < 0.05), though enzymatic activity appeared to behave in a similar fashion in both breeds at 5% level of significance ( P < 0.05). This rule out the role of HSF1 expression level on the activity of enzymes involved in oxidative stress in vitro in zebu and crossbred cattle.

    The question of whether the adaptability and production performance in goats may be enhanced using a crossbreeding program between bucks of a native and heat-tolerant breed and does of an exotic and dual-purpose breed was approached and examined herein by comparing purebred Aardi and Damascus goats and their crossbred lines (i.e., 1/2 Aardi 1/2 Damascus (½A½D) and 1/4 Aardi 3/4 Damascus (¼A¾D)) reared in a region characterized by dry and hot bioclimatic conditions. Twenty-four male 6-month-old kids randomly segregated into four groups (six replicates/group) were used for the experiment. Climatic, thermo-physiological, biophysiological, metabolic, blood hematological, and biochemical measurements were all determined. The obtained results indicated that such a program was proven to be successful. This conclusion was demonstrated by the findings that crossbred goats (i.e., 1/2A1/2D and 1/4A3/4D) under such bioclimatic conditions were able to show ( P goats as well as manifested ( P goats. Accordingly, these evidences could emphasize that the crossbreeding may enable these animals to display a simultaneous improvement of both traits by the possible benefits that could arise from heterosis and breed complementarity. Researches dealing with this aspect may very well improve our understanding of goat's production and welfare under harsh environmental conditions. Future studies should include an economic analysis of traits that have the potential to impact the overall profitability to a vertically coordinated system.

    Full Text Available Cattle (Bos taurus and Bos indicus are organised on the basis of leadership and dominance in such a manner that a disturbance by an external stressor causes negative effects on their health, productivity, well-being, and behaviour. One of these effects is the excessive release of glucocorticoids, which results in increased alertness. We evaluated the action of exogenous oxytocin (OT on serum cortisol levels in crossbred Red Angus heifers. Twelve Red Angus crossbred heifers were moved daily from the pasture to the corral in weeks 1 and 2 for adaptation to human contact and handling in the cattle crush. In weeks 3 and 4, they were divided into two groups of six (T1 and T2. The T1 group was administered 20 IU (2 mL of OT via intramuscular injection and the T2 group was administered 2 mL of saline solution 0.85% (SS. In weeks 5 and 6, they were only contained in the cattle crush for evaluation. On days 01, 07, 14, 21, 28, 35, and 42, blood samples were collected by jugular venepuncture in vacuum tubes without anticoagulants. Then, serum cortisol levels were measured using a radioimmunoassay. In the period of adaptation, during weeks 1 and 2, serum cortisol levels decreased in both the groups, with higher levels in the SS group; the same result was obtained in weeks 5 and 6. During treatment, however, there was a significant difference between the two groups in week 4, with a reduction in cortisol levels in the OT group. This result suggests a modulator effect of OT on neuroendocrine response to stress.

    Full Text Available Digestibility of ruminant feeds is greatly determined by ruminal fermentation which in turn is greatly affected by micro-ecology of the rumen. Manipulation of micro-ecology such as supplementing with various yeasts or micro elements could improve digestibility of the feed. The effect of Comin+ (R1 and Zn-biocomplex (R2 alone or their combination (R3 on performance of Ettawa Crossbred kids, fed concentrate containing Aspergillus oryzae (R0 was studied. Twenty four Ettawa Crossbred kids (6-8 month of age; initial liveweights =16.63±2.10 kg were divided into 4 groups. Feeds given were King grass (Pennicetum purpuroides ad libitum and concentrate. The observations were carried out for 16 weeks with 2 weeks adaptation period and the experiment was conducted in a completely randomized design with 4 treatments and 6 replications. The results showed that supplementations significantly (P < 0.05 increased total DM intakes from 685 g/d (R0 became 748, 711 and 858 g/d; and grass DM intakes from 304 g/d (R0 became 373, 331 and 479 g/d for R1, R2 and R3, respectively. Digestibilities of DM, NDF and DE/GE were not affected by supplementation, but supplementations significantly (P < 0.05 affected digestibilities of ADF and CP. Supplementation also significantly improved (P < 0.05 ADG from 65.18 g/d (R0 became 94.64, 83.04 and 90.77 g/d; and FCR from 10.51 (R0 became 7.82, 8.36 and 9.46 for R1, R2 and R3, respectively. It was concluded that supplementation of Comin+ (R1 gave the best growth performance of Ettawa Croosbred goats, where ADG and FCR improved by 45.20% and 34.40%.

    The productive and reproductive characteristics of Brown Swiss (B) cross-bred cows were investigated by comparing with those of Holstein (H) cows housed in the same barn. Additionally, their hair cortisol levels were analyzed to evaluate the extent of stress experienced during dry and lactation periods. B cross-bred cows had lower milk yields and higher milk fat rates than H cows. Reproductive records showed that days from parturition to first artificial insemination (AI) in B cross-bred (n = 16) and H (n = 27) cows were not significantly different, but conception rate at first AI of B cross-bred cows tended to be higher than that of H cows. Percentage of B cross-bred cows that resumed ovarian cyclic activity within 45 days after parturition was higher than that of H cows (6/6 (100%) and 5/11 (45.5%), P cows had higher body condition scores at that time. Hair cortisol level at 60 to 90 days after parturition in H cows increased significantly compared with in the dry period, and it was higher than that of B cows during the same period. These results suggest that B cross-bred cows experience less metabolic stress during early lactation, which may result in earlier resumption of reproductive function. © 2017 Japanese Society of Animal Science.

    The experiment was carried out during August (hot climate) on twelve pregnant cows of six crossbred (50% native Baladi and 50% Brown Swiss) and six native Baladi pregnant cows in the same age and the second parity during their mid-pregnancy as detected by rectal palpation. The experiment was repeated during December (mild climate) on similar twelve pregnant cows. Blood sample was obtained from each cow at the end of August (first group) and at the end of December (second group) to obtain heat shock protein genes expression (HSP72, HSP70.01, HSP70, HSP47, k Dalton and Actin) in pregnant cows under mild and hot climate to find out, which breed is more tolerant to heat stress and to estimate offspring birth weight and their growth performances during suckling period. Comparison was made between hot climate cows group and mild climate cows group to estimate heat- induced changes in both breeds in expression level of the Hsp genes and to compare with their neonate birth weight and growth performances during suckling period. The results revealed that expression level of the Hsp genes (Hsp72, Hsp70.1, Hsp70 and Hsp 47) was higher (p<0.01) in hot season compared to that of mild season. Expression level of the Hsp genes (Hsp70.1, Hsp70 and Hsp 47) was higher (p<0.05) in crossbred cows than in Baldi cows under summer hot season. This indicates that crossbred cows are less heat tolerant than Baladi cows under heat stress climate. Heat induced decrease (p<0.01) in offspring birth weight in Baladi and crossbred by 18.1% and 25%, respectively, in weaning weight by 14.61% and 23.14%, respectively and in body weight gain by 14.61% and 21.18%, respectively

    Full Text Available Purebred and crossbred calves (n = 3,871 were selected that were born in the sub-region of the Pantanal of Aquidauana (Brazil, derived from Nellore, Brangus, Wagyu, and ½ Brangus + ½ Nellore cows, which were artificially inseminated by bulls of the Aberdeen Angus, Red Angus, Brangus, Nellore, and Wagyubreeds. Parameters such as weaning weight, daily gain from birth to weaning, and the number of days to gain 160 kg, were assessed inthese calves and phenotypic correlations between the traits were evaluated. Data were analyzed using two statistical models. The first model included sire breed effects, the genetic group of the cow, sex, year of birth (AN, birth season (EN, and the interaction AN * EN. The second model included the genetic group of the calf, sex, AN, EN, and the interaction AN * EN. The genetic group of the cow and calf and the interaction AN * EN did not significantly affect body weight (p < 0.05. The average weaning weights of progeny were as follows: Aberdeen Angus bulls, 177.70 ± 3.28 kg; Red Angus, 180.31 ± 3.46 kg; Brangus, 181.48 ± 3.15 kg; Nellore, 175.43 ± 3.60 kg; and Wagyu, 173.16 ± 2.96 kg.

    This study was conducted on 30 freshly parturated multiparous crossbred dairy cows possessing three levels of Holstein Frisian genetic makeup (62.5, 75.0, and 87.5%). Data on temperature humidity index (THI) were classified into comfortable (≤ 71), mild stress (72-79), moderate stress (80-89), and stressful (≥90) zone. Results showed that serum cortisol concentration increased significantly (P stressful condition irrespective of genetic makeup compared to the other zones. Daily milk yield (DMY) was significantly (P stressful condition. Triglyceride was significantly higher in cows with genetic makeup 87.5% compared to the others, while total serum protein was significantly (P stressful conditions. The mean concentration of cortisol and protein increased linearly from comfort to the stressful condition, while mean serum triglyceride, glucose, progesterone (P 4 ), and luteinizing hormone (LH) decreased by moving from comfort to stressful conditions. Results also indicated that higher cortisol level in higher grade crossbred cows was adversely associated with LH concentration and milk yield under thermal stress conditions. Greater triglyceride in high-grade crossbred (87.5%) cows indicates higher fat mobilization reflecting a negative energy balance. We concluded that heat stress increased blood cortisol and protein, and reduced milk yield in dairy cows irresptive of the genetic makeup. In addition, there was no significant difference in blood metabolites and daily milk yield in the different levels of genetic makeup cows.

    Due to the absence of accurate pedigree information, it has not been possible to implement genetic evaluations for crossbred cattle in African small-holder systems. Genomic selection techniques that do not rely on pedigree information could, therefore, be a useful alternative. The objective of this study was to examine the feasibility of using genomic selection techniques in a crossbred cattle population using data from Kenya provided by the Dairy Genetics East Africa Project. Genomic estimated breeding values for milk yield were estimated using 2 prediction methods, GBLUP and BayesC, and accuracies were calculated as the correlation between yield deviations and genomic breeding values included in the estimation process, mimicking the situation for young bulls. The accuracy of evaluation ranged from 0.28 to 0.41, depending on the validation population and prediction method used. No significant differences were found in accuracy between the 2 prediction methods. The results suggest that there is potential for implementing genomic selection for young bulls in crossbred small-holder cattle populations, and targeted genotyping and phenotyping should be pursued to facilitate this.

    Lactoferrin (Lf) gene promoter was screened for the presence of single nucleotide polymphism in indigenous and crossbred cattle from North India and to evaluate its association with Mastitis. Study revealed the presence of genetic variation in regulatory region of bovine Lactoferrin gene using PCR-RFLP technique. Three genotypes namely GG, GH and HH were identified. A single nucleotide change, from guanine to adenine at 25th position was found to be significantly associated (pmastitis in indigenous Sahiwal and crossbred Karan Fries cattle maintained at organised herd of National Dairy Research Institute, Karnal. A non-significant association was observed between subclinical mastitis, somatic cell score (SCS), and GG genotype in Karan Fries cattle, however, a lower SCS was observed in animals having GG genotype. Overall a lower incidence of clinical mastitis was recorded in those animals having GG genotype of Lf in Sahiwal and Karan Fries (KF) cattle. The SNP identified in the promoter region may effect expression lactoferrin protein, which may lead to different levels of antibacterial and anti-inflammatory activity of Lf gene. Results from this study indicated the probable role played by Lactoferrin promoter to serve as candidate gene for mastitis susceptibility among indigenous and crossbred milch cattle.

    Crossbred cattle are more prone to mastitis in comparison to indigenous cattle. Toll-like receptor 4 (TLR4) recognizes pathogen ligands, for example, lipopolysaccharide (LPS) endotoxin from Escherichia coli and mediates signaling to initiate innate and adaptive immune responses. Mutations in TLR4 can compromise the host immune response to certain pathogens, so it may be a potential candidate for marker assisted selection to enhance mastitis resistance in dairy cattle. Hence, in this study role of bovine TLR4 gene in mastitis resistance was investigated by association as well as expression profiling analysis in crossbred cattle. The animals were divided into mastitis affected and unaffected groups on the basis of history of animals and California Mastitis Test (CMT). PCR-SSCP and Sequence analysis revealed three genotypes of coreceptor binding region 1 (CRBR1) fragment of TLR4 gene namely AA, AB, and BB in both groups of cattle. The logistic regression model did not show any significant effect of these genotypes on the occurrence of clinical mastitis. Moreover, in vitro challenge of peripheral blood mononuclear cells (PBMCs) with LPS failed to show any association of the genotypes with TLR4 gene expression. In a nutshell, in the present study enough evidence was not found for association of the SNP variants of CRBR1 fragment of TLR4 gene with mastitis susceptibility in crossbred cattle.

The results imply that the wild and farmed crustaceans markets are interacting through substitution effects. Hence, the markets have the capability to shield volatile and rising prices that would emanate......In this paper the price dynamics and the degree of market integration in the German crustaceans market is examined using cointegration methods. The study focuses on wild caught cold water shrimp, farmed warm water shrimp as well as lobster and derives implications for the fisheries sector....... In the analysis, both the import market and the retail market price reactions are distinguished. Therefore, it is evaluated how price changes affect competing commodities within and between the value chain of a given crustaceans commodity.

    Crossbreeding is a common strategy used in tropical and subtropical regions to enhance beef production, and having accurate knowledge of breed composition is essential for the success of a crossbreeding program. Although pedigree records have been traditionally used to obtain the breed composition of crossbred cattle, the accuracy of pedigree-based breed composition can be reduced by inaccurate and/or incomplete records and Mendelian sampling. Breed composition estimation from genomic data has multiple advantages including higher accuracy without being affected by missing, incomplete, or inaccurate records and the ability to be used as independent authentication of breed in breed-labeled beef products. The present study was conducted with 676 Angus-Brahman crossbred cattle with genotype and pedigree information to evaluate the feasibility and accuracy of using genomic data to determine breed composition. We used genomic data in parametric and non-parametric methods to detect population structure due to differences in breed composition while accounting for the confounding effect of close familial relationships. By applying principal component analysis (PCA) and the maximum likelihood method of ADMIXTURE to genomic data, it was possible to successfully characterize population structure resulting from heterogeneous breed ancestry, while accounting for close familial relationships. PCA results offered additional insight into the different hierarchies of genetic variation structuring. The first principal component was strongly correlated with Angus-Brahman proportions, and the second represented variation within animals that have a relatively more extended Brangus lineage-indicating the presence of a distinct pattern of genetic variation in these cattle. Although there was strong agreement between breed proportions estimated from pedigree and genetic information, there were significant discrepancies between these two methods for certain animals. This was most likely due

    Full Text Available The effects of the carbohydrate composition of finishing diet (fed from 80 to 107 kg of body weight and the length of pre-slaughter fasting on pork quality were studied in a 2 × 2 factorial experiment with 80 crossbred pigs. The control finishing diet was based on barley and soybean meal, and the fibrous finishing diet was based on barley, barley fibre, faba beans, and rapeseed cake. These diets contained 465 and 362 g starch and 177 and 250 g dietary fibre per kg, respectively. The fasting times of 25 and 41 h were obtained by giving the pigs their last meal at different times. Longer fasting lowered the glycolytic potential of the longissimus lumborum muscle (P = 0.01, whereas the finishing diet had no effect. Different muscles responded differently to the treatments. Longer fasting increased the ultimate pH of the semimembranosus muscle (P = 0.02, but did not affect that of the longissimus lumborum and semispinalis capitis muscles. The finishing diets did not affect the ultimate pH of the investigated muscles. A diet × fasting time interaction was seen in the lightness of the semimembranosus muscle (P = 0.05. The fibrous diet resulted in darker meat than the control diet did in pigs that were fasted for 25 h (P < 0.05. Longer fasting darkened the meat colour in pigs fed the fibrous diet (P < 0.05 but not in those fed the control diet. The meat from the semispinalis capitis muscle was darker in pigs fed the fibrous than those fed the control diet (P = 0.04. The treatments did not affect the colour of the longissimus lumborum muscle. Longer fasting decreased drip loss from the meat of pigs fed the control diet (P < 0.05. The eating quality of the pork was not influenced by the finishing diets or the fasting time. The pigs also grew equally fast on both finishing diets. In conclusion, a moderate alteration in the carbohydrate composition of a finishing diet or longer pre-slaughter fasting can have some effects on pork quality in crossbred pigs

    Full Text Available Aim: Uttarakhand is a relatively new state and many cross bred cattle were introduced to boost the milk yield of the state. Despite all efforts the milk yield of dairy in Uttarakhand is comparatively low. In our study, we assessed the effect of heat stress on milk production, using thermal humidity index (THI in high (cross bred cattle and low milk producing (LMP cows (native cows in Dehradun district of Uttarakhand, India. Materials and Methods: Effect of heat stress was measured on high and LMP cross bred cows using THI maintained on standard feeding and nutritional value. Daily ambient temperature and relative humidity were recorded to calculate the THI. Daily milk production was noted to verify the effect of heat stress. Furthermore, profile the thyroid hormones using enzyme-linked immunosorbent assay. Results: Low yielding cows did not show any significant change when the THI was above 72 from month June to October during stress condition. But high yielding cows shows a significant decrease (p<0.05 in milk yield when THI was above 80 (severe stress zone in the month of June to October and milk production decrease from an average of 18±1.4 to 10.9±0.92 L whereas in November-December when THI declines in the zone of comfort the milk yield did not show significant rise. The thyroid hormones (T3 and T4 level were found lower in summer heat stress condition for a high yielding cattle. Conclusion: Summer heat stress significantly decreased milk yield in high milk producing (HMP crossbred cows. As THI rises from comfort zone to stress zone milk yield decreased by 30-40% and this loss in milk production is irreversible. Management strategies should be needed as environmental control housing is suggested for the HMP crossbred cattle to minimize the heat stress. If all the dairies with cross bred cattle implement these small modifications in housing of cattle, there would be a huge increase in milk production.

    Advances in mineral nutrition of goats have been made during the last decade, especially in our understanding of Ca and P requirements. However, few studies have focused on the mineral requirements of crossbred Boer goats in their growth phase. Our objective for this study was to determine the macromineral (Ca, P, Mg, K, and Na) requirements for the maintenance and growth of intact, male three-fourths Boer × one-fourth Saanen kids (n = 34; 20.5 ± 0.24 kg of initial BW). Two trials were conducted: 1 for maintenance and 1 for growth requirements. In the maintenance trial, 28 kids were used. The baseline (BL) group consisted of 7 randomly selected kids averaging 21.2 ± 0.36 kg BW and 122 d old. The remaining kids (n = 21; age 168 ± 5 d) were randomly allocated into 7 slaughter groups (blocks) including 3 animals distributed among 3 amounts of DMI (treatments: ad libitum and restricted to 70 or 40% of ad libitum intake). Animals in a group were slaughtered when the ad libitum-treatment kid in the block reached 35 kg BW. The BL and ad libitum-fed groups in the maintenance trial were also part of the growth trial. Therefore, in the growth trial, 20 kids fed for ad libitum intake were used as follows: 7 kids slaughtered at 21.2 ± 0.36 kg BW (BL), 6 kids slaughtered at 28.2 ± 0.39 kg BW (intermediate slaughter), and 7 kids slaughtered at 35.6 ± 0.36 kg BW. Empty whole bodies of the kids (head + feet, hide, internal organs + blood, and carcass) were weighed, ground, mixed, and subsampled for chemical analyses. Daily maintenance requirements, calculated using the comparative slaughter technique (P kids from 20 to 35 kg BW. This study indicated that the net mineral requirements for Boer crossbred goat kids may be different from those of purebred or other genotypes, and more data are needed for goats in general.

    Since economization of medicine continues, marketing is becoming more and more important. To shape marketing activities in correspondence with their professional ethics, physicians need some basic knowledge about marketing. The process of marketing consists of SWOT-analysis, market segmentation, market differentiation, positioning and the marketing-mix with ist most important component, the marketing communication. Specific aspects in the marketing of medical services derive from their nature as a service and the determinants of perceived service quality.

  20. THE USE OF DIETARY FATS AND CONCENTRATES TO ALLEVIATE THE NEGATIVE ENERGY BALANCE IN CROSSBRED COWS IN EARLY LACTATION

    Directory of Open Access Journals (Sweden)

    Carlos F. Aguilar-Pérez

    2014-08-01

    Full Text Available Energy balance (EB is defined as the difference between energy intake and energy expenditure. Fertility in the high-merit cow has been adversely associated with high milk production, low intake of energy and mobilisation of body reserves in early lactation, which combine in the term negative energy balance (NEB.  The timing of insemination usually coincides with peak milk yield, when dairy cows are often in NEB. Crossbred cows (Bos taurus x Bos indicus in the tropics have comparatively lower nutrient requirements and different partition of nutrients than high merit dairy cows. Thus, it would be expected that both the magnitude and length of negative energy balance were different in a crossbred cow. Because of marked differences compared with high-merit cows, crossbred cows in the tropics would be expected to show greater response to additional energy in early lactation improving their energy status and hence reproductive performance. Knowing the influence of nutrition on reproduction, many methods have been proposed for manipulating the diet to avoid or to alleviate negative energy balance. The use of fats is one alternative, which has been extensively studied in dairy and beef cows but with inconclusive results. Another alternative is to use starch-based concentrates, taking into account level of inclusion and quality and availability of pasture, in order to avoid substitution effects and to get maximum profits. Two experiments were carried out in Yucatan Mexico, in order to evaluate the use of bypass fats (calcium soaps of long-chain fatty acids, CAFA or a starch-based concentrate to alleviate the NEB in grazing crossbred cows in early lactation. The NEB in early lactation was successfully avoided by the use of the starch-based concentrate but not by the use of bypass fats, this due to a reduction in the grass DM intake. It was concluded that crossbred cows in the tropics may experience a period of NEB postpartum, which can be avoided if

    Full Text Available Consumption of white rice predisposes some Asian populations to increased risk of type 2 diabetes. We compared the postprandial glucometabolic responses to three newly-developed crossbred red rice variants (UKMRC9, UKMRC10, UKMRC11 against three selected commercial rice types (Thai red, Basmati white, Jasmine white using 50-g carbohydrate equivalents provided to 12 normoglycaemic adults in a crossover design. Venous blood was drawn fasted and postprandially for three hours. Glycaemic (GI and insulin (II indices, incremental areas-under-the-curves for glucose and insulin (IAUCins, indices of insulin sensitivity and secretion, lactate and peptide hormones (motilin, neuropeptide-Y, orexin-A were analyzed. The lowest to highest trends for GI and II were similar i.e., UKMRC9 < Basmati < Thai red < UKMRC10 < UKMRC11 < Jasmine. Postprandial insulinaemia and IAUCins of only UKMRC9 were significantly the lowest compared to Jasmine. Crude protein and fiber content correlated negatively with the GI values of the test rice. Although peptide hormones were not associated with GI and II characteristics of test rice, early and late phases of prandial neuropeptide-Y changes were negatively correlated with postprandial insulinaemia. This study indicated that only UKMRC9 among the new rice crossbreeds could serve as an alternative cereal option to improve diet quality of Asians with its lowest glycaemic and insulinaemic burden.

    Full Text Available Eight bulls of Ongole Crossbred (OC cattle with initial body weight (BW of 297 + 26 kg (CV =8.75% fed rice straw treated with urine (RU (ad libitum were divided into two groups (each fourheads to determine the effect of concentrate feeding level on efficiency of eating behavior. The cattlewas given concentrate feeding composed of beer cake and rice bran to make 14% crude protein at 1%and at 2% BW for RUC1 and RUC2 group, respectively. Eating behavior was measured for 3x24 hoursand was performed twice at weeks 2 and 6 of the study. Data obtained were analyzed by t-test. Theresults showed that the level of concentrate feeding affected the intake of urinated rice straw (P<0.01and daily BWGain (P<0.05, but the effect was not found (P>0.05 on DMI, length time for eating(196.5 vs. 221.5 min/d, length time for rumination (351.0 vs. 449.4 min/d, efficiency of eating time(37.21 vs. 37.67 gDM/min and efficiency rumination time (21.43 vs. 18.50 gDM/min. This researchshowed that concentrate feeding at 2% BW did not alter the efficiency of eating time and ruminationcompared to 1% BW, although able to improve BWG of OC cattle.

    The present study was carried out to analyze the disposal rate in different age groups of Karan Fries (KF) males in National Dairy Research Institute herd. Records on 1740 KF crossbred bulls born during the period 1997-2012 were collected with an objective to ascertain the effect of genetic and non-genetic (Period of birth and season of birth) factors on the disposal pattern of KF males. The percent of animals disposed from the herd due to mortality and culling was calculated by proportion using descriptive statistics. The data were subjected to Chi-square test to test the difference due to different factors. Overall disposal rate for the different age groups of 0-1 m, 1-2 m, 2-3 m, 3-6 m, 6-18 m, 18 m-3 year and 3-5 year were calculated as 17.9, 16.3, 14.2, 25.8, 49.0, 37.6 and 51.65%, respectively. In the age groups, 3-6 m, 6-18 m and 3-5 year, effect of periods of birth were found to be statistically significant (page group except in 3-5 year age group. Differences in overall disposal rate due to genetic group were statistically significant (page groups. Overview of the results indicated that higher overall disposal rate in age group of 1 month was due to mortality while, in the age groups of >1 month, culling was the primary cause.

    2013-06-01

    The contribution of dry season silage feeding on daily milk yield (MY) and dairying profitability in terms of income over feed cost (IOFC) was evaluated in dual-purpose cattle production systems in Honduras. MY records of 34 farms from two milk collection centres were collected over a 2-year period. Farms were surveyed to obtain information on the type, quantity and cost of supplemented feed, breed type and number of lactating cows in each month. Farms were classified in silage farms (SF, with a short silage supplementation period), non-silage farms (NSF) and prototype farms (PF, with an extended silage supplementation period). Data were analysed using descriptive statistics and a linear mixed model approach. PF had significantly higher MY than SF and NSF but, due to higher expenses for both concentrate and silage, similar IOFC compared to NSF. SF had similar MY but lower IOFC compared to NSF, due to higher feed expenses. The effect of silage feeding, particularly maize silage, on MY was significant and superior to that of other forage supplements. Silage supplementation contributed to the highest MY and IOFC on farms with crossbred cows of >62.5 % Bos taurus and to the second highest profitability on farms with >87.5 % Bos indicus share. It is concluded that silage can play an important role in drought-constrained areas of the tropics and can contribute to profitable dairying, irrespective of breed.

    Full Text Available Aim: To determine the serum variations of two major acute phase proteins, serum amyloid A (SAA and haptoglobin (Hp levels in crossbred endometritis cows following pre and post immunomodulation therapy. Materials and Methods: 21 endometritis cows were randomly assigned to three groups (n=7 and treated with three different immunomodulators while seven healthy cows served as control. Uterine flushing collected from all animals was subjected to bacteriological study and serum samples were analyzed for SAA and Hp by sandwich ELISA method. Results: Escherichia coli was most prevalent Gram-negative bacteria (6.02 × 106 CFU/ml while Staphylococcus (0.86 × 106 CFU/ml and Streptococcus (0.52 × 106 CFU/ml were most predominant Gram-positive species isolated from uterine flushing. The pre-treatment SAA values (μg/ml varied significantly (p<0.01 between the treatment groups whereas no difference was observed in post-treatment groups. No significant difference (p<0.01 was observed for Hp values between the treatment groups, but the mean SAA (μg/ml and Hp (μg/ml levels were significantly (p<0.01 higher in pre-treatment when compared to post-treatment within the groups. Conclusion: In the diagnosis and monitoring of bovine endometritis, both SAA and Hp might serve as reliable biomarkers.

    The paper reports on the reproductive performance of smallholder dairy cross-bred cattle in Malaysia, as monitored by milk progesterone radioimmunoassay and rectal palpation. Infertility was identified as the major problem faced by the smallholder farmers. The results show that there is a strong and significant association between suckling and delayed post-partum ovarian activity. The longer calving intervals in smallholder dairy herds compared with those in institutional herds are due to inactive ovaries rather than failure to detect oestrus. The use of a progesterone releasing intravaginal device (PRID) for treatment of anoestrus resulted in 93% of cows cycling, with a conception rate of 46% to insemination at the induced oestrus. Cows that suckled their calves had significantly longer calving intervals. The mean body score for cattle on smallholder herds was 3.8 -+ 1.1, and fertile cows had significantly higher scores than infertile cows. There was strong evidence to suggest that increased body scores corresponded to shorter intervals between calving and resumption of sexual activity, calving and conception, and successive calvings.

    The objective of this study was to evaluate the influence of diets with increasing concentrate levels (170, 340, 510 and 680 g/kg of total dry matter) on dry matter intake, digestibility, performance and carcass characteristics of 25 Holstein-Zebu crossbred dairy steers in a feedlot. A completely randomized design was used, and data were submitted to analysis of variance and regression. The dry matter intake and digestibility coefficients of all nutrients increased linearly. The total weight gain and average daily gain added 1.16 kg and 9.90 g, respectively, for each 10 g/kg increase in concentrate. The empty body weight, hot carcass weight and cold carcass weight responded linearly to increasing concentrate. The hot carcass yield and cold carcass yield, gains in empty body weight and carcass gain were also influenced, as were the efficiencies of carcass deposition and carcass deposition rate. It is concluded that increasing concentrate levels in feedlot diets increase the intake and digestibility of dry matter and other nutrients, improving the feed efficiency, performance and physical characteristics of the carcass. Furthermore and of importance concerning the climate change debate, evidence from the literature indicates that enteric methane production would be reduced with increasing concentrate levels such as those used.

    The credit derivative market was established at the beginning of the 1990s since the emergence of credit derivatives fits the rapid development of the whole derivatives market. However, compare to other derivative market, this market is still small and incomplete. As with other derivatives, credit derivatives can be used to either take more risk or hedge it, hence various credit derivatives instruments are accepted and widely used by market participants such as banks, insurance companies, etc...

  16. Genome Wide Association Studies (GWAS Identify QTL on SSC2 and SSC17 Affecting Loin Peak Shear Force in Crossbred Commercial Pigs.

    Directory of Open Access Journals (Sweden)

    Chunyan Zhang

    Full Text Available Of all the meat quality traits, tenderness is considered the most important with regard to eating quality and market value. In this study we have utilised genome wide association studies (GWAS for peak shear force (PSF of loin muscle as a measure of tenderness for 1,976 crossbred commercial pigs, genotyped for 42,721 informative SNPs using the Illumina PorcineSNP60 Beadchip. Four 1 Mb genomic regions, three on SSC2 (at 4 Mb, 5 Mb and 109 Mb and one on SSC17 (at 20 Mb, were detected which collectively explained about 15.30% and 3.07% of the total genetic and phenotypic variance for PSF respectively. Markers ASGA0008566, ASGA0008695, DRGA0003285 and ASGA0075615 in the four regions were strongly associated with the effects. Analysis of the reference genome sequence in the region with the most important SNPs for SSC2_5 identified FRMD8, SLC25A45 and LTBP3 as potential candidate genes for meat tenderness on the basis of functional annotation of these genes. The region SSC2_109 was close to a previously reported candidate gene CAST; however, the very weak LD between DRGA0003285 (the best marker representing region SSC2_109 and CAST indicated the potential for additional genes which are distinct from, or interact with, CAST to affect meat tenderness. Limited information of known genes in regions SSC2_109 and SSC17_20 restricts further analysis. Re-sequencing of these regions for informative animals may help to resolve the molecular architecture and identify new candidate genes and causative mutations affecting this trait. These findings contribute significantly to our knowledge of the genomic regions affecting pork shear force and will potentially lead to new insights into the molecular mechanisms regulating meat tenderness.

    Full Text Available Although Etawah Crossbred (PE goat is considered to be dual purpose (meat and milk goat, it is mainly raised for meat production. Since early 1990, there has been a growing interest of the farmer in some places to raise PE goat for milk production without sacrificing its role to produce kids for meat. The average birth weight of PE kids varied widely (2.8 – 5 kg, resulted in a high variation in weaning weight (9 – 14 kg. A high pre-weaning mortality of 10 – 50% was a major source of lost in goat production in Indonesia, partly due to low birth weight and/or miss mothering ability. Young female PE goat reached puberty at 8 – 12 months of age and at body weight of about 18 – 22 kg or about 53 – 60% of mature body weight. Gestation length varied between 142 – 156 days, and first post partum estrous occurred at 3 – 5 months after parturition took place, resulted in 8 – 10 months of kidding intervals. Lactation period lasted for 5 – 8 months with total milk yield of 177 – 203 kg/lactation (average 0.85 kg/day. Although milk yield of PE goat was not as high as milk yield of some other dairy goats, the ability of PE goat to cope with harsh local environment, particularly climate and feed conditions, was an advantage. Therefore, raising PE goat would still be an important part of farmer activities in the rural areas in Indonesia.

    The aim of this study was to evaluate the consumption, performance, feed efficiency, glucose concentration, and the cost per kilogram of weight gain of crossbred Holstein-Gyr heifers (n = 33) subjected to one of the three waste milk step-down strategies: 6L-30d/4L-60d/2L-90d (T1), 6L-45d/4L-60d/2L-90d (T2), and 8L-30d/6L-60d/3L-90d (T3). Heifers were weaned at the age of 91 days. Water and starter were provided ad libitum. The average waste milk intake was higher in T3 than in T1 and T2 strategies until 30 days and between 60 and 90 days. The starter intake did not differ among the strategies until 45 days, but it was higher in strategy T1 than in strategy T3 between 60 and 90 days. The waste milk step-down strategy did not influence the total dry matter intake, average daily gain, body weight, and feed efficiency. Glucose concentrations in plasma varied within a range that could be considered normal and were similar among the treatments. The average cost per kilogram of weight gain was the lowest in strategy T1 (US$3.0) compared to that in the other strategies (T2, US$3.2, and T3, US$3.6). The 6L-30d/4L-60d/2L-90d waste milk step-down strategy was the most effective, since it increased the starter intake, led to normal glucose concentrations in plasma, and caused similar weight gain compared with the other strategies; however, it had a lower cost per kilogram.

    Full Text Available The effect of supplementing purebred and crossbred Merino lambs with Arthrospira platensis (Spirulina on plasma metabolite concentrations under pasture-based management system and the influences of sire breed and sex were investigated. A completely randomized experimental design balanced by 4 sire breeds (Merino, White Suffolk, Dorset and Black Suffolk, 3 Spirulina supplementation levels (0, 100 and 200 ml representing the control, low and high, respectively and 2 sexes (ewe and wether lambs was utilised. All lambs had ad libitum access to the basal diet of ryegrass pastures and barley. Lambs in the treatment groups were individually drenched daily with Spirulina prior to being released with the control group of lambs for grazing over a 6-week period following a 3-week adjustment phase. At the start and completion of the feeding trial, blood samples were centrifuged and plasma metabolites measured. Data were analysed with Spirulina supplementation level, sire breed, sex and their second-order interactions fitted as fixed effects and metabolite concentrations as dependent variables. Gamma-glutamyl transferase (GGT concentrations decreased (from 79.40 to 69.25 UI and glucose increased (from 3.81 to 4.19 mmol/L as the level of Spirulina supplementation increased from 0 ml in the control to 200 ml in the high treatment groups (P < 0.05. Lambs supplemented at low Spirulina levels had the highest creatinine concentrations (61.75 μmol/L. Interactions between sex and supplementation level significantly affected glucose, aspartate aminotransferase (AST and Mg concentrations (P < 0.05, while sire breed and supplementation level interactions influenced albumin to globulin (A/G ratio, creatinine and GGT concentrations. It was demonstrated that Spirulina supplementation does not negatively impact lamb health and productivity.

    An investigation was carried out on a family of Limousin-Jersey crossbreds exhibiting low fertility in the females, to determine the impact of a previously identified X-autosome translocation (X-AT) on the reproductive performance of the carrier cows. Three of the identified translocation carriers, including a cow and two of her daughters, were maintained at our University Research Station and artificially inseminated periodically with semen from different bulls of known fertility. Attempts to breed the X-AT carriers resulted in high rates of return to estrus between days 28 and 60, abortions between days 121 and 235 after insemination, and a total of 13 live births including 4 translocation carrier calves. Results of superovulation and embryo retrieval trials on X-AT carriers revealed significantly higher proportions of unfertilized and uncleaved ova and abnormal embryos compared to those from normal cows, and no pregnancy in the recipients transferred with morphologically normal blastocysts from X-AT carriers. While the higher rates of failed fertilization and cleavage, abnormal embryos and return to estrus in X-AT carriers could be attributed to chromosome imbalance expected in their gametes, the relatively high prevalence of abortion (late in gestation) was unexpected. Our observations on the fetuses expelled by X-AT carriers after 5 months of gestation indicated that a majority (three out of four) of these fetuses were products of abnormal (3:1) segregation in meiosis I and that these chromosomally unbalanced (hyperdiploid) conceptuses were able to survive early embryogenesis and fetal life up to the end of the second trimester. We hypothesize that their relatively long in utero life and the absence of any overt birth defects may be attributable to the type of chromosomes over-represented in these fetuses and that their eventual expulsion may have been the result of selection against the clonal population of cells in which the altered X carrying a segment of

    This experiment was conducted in the bovine farm of Experimental Farms Project of Nuclear Research Centre, Atomic Energy Authority of Egypt, which is located in the desert area of Inshas. DNA fingerprinting analysis using arbitrarily primed-polymerase chain reaction (AP-PCR) is a powerful technique for detecting markers that can be used for establishment of genetic variations, molecular relationships and taxonomy identifications between different animal breeds. In the present study, for detecting the genetic relationship between Egyptian bovine Baladi female and crossbred calves (Brown Swiss Baladi) previously imported, blood samples were collected from 10 animals (5 for each breed), DNA was isolated and AP-PCR technique was applied using four random primers to establish fingerprinting and molecular relationship between the two breeds using radioactive 32 P-dCTP for labelling the fragments amplified in PCR.. The band sharing coefficient between the two groups was calculated, and the quantity of DNA was correlated with average daily gain (ADG). The data showed non- significant correlation between the quantity of DNA and average daily gain. Also, data showed the powerful of the technique for detecting the molecular variations and there is a specific pattern for certain breeds especially when using the Knp-X primer. The present study also revealed that there was a close genetic relationship between the Egyptian Baladi breed and the crossbred calves (Brown Swiss Baladi) in about seventy percent of the genetic materials as represented by band-sharing (BS) = 0.7. In conclusion, the AP-PCR technique is effective in detecting the molecular variations between different breeds and provides a potential tool for studying the molecular relationships. The native Egyptian calves are genetically closely related to crossbred (Brown Swiss Baladi) by about 70%. Further studies on the large scale are needed using different primers for detecting patterns specific for each breed and

    This study aimed to determine the impact of replacing soybean meal with peanut cake in the diets of crossbred Boer goats as determined by carcass characteristics and quality and by the fatty acid profile of meat. Forty vaccinated and dewormed crossbred Boer goats were used. Goats had an average age of 5 mo and an average BW of 15.6 ± 2.7 kg. Goats were fed Tifton-85 hay and a concentrate consisting of corn bran, soybean meal, and mineral premix. Peanut cake was substituted for soybean meal at levels of 0.0, 33.33, 66.67, and 100%. Biometric and carcass morphometric measurements of crossbred Boer goats were not affected by replacing soybean meal with peanut cake in the diet. There was no influence of the replacement of soybean meal with peanut cake on weight at slaughter ( = 0.28), HCW ( = 0.26), cold carcass weight ( = 0.23), noncarcass components of weight ( = 0.71), or muscularity index values ( = 0.11). However, regression equations indicated that there would be a reduction of 18 and 11% for loin eye area and muscle:bone ratio, respectively, between the treatment without peanut cake and the treatment with total soybean meal replacement. The weights and yields of the commercial cuts were not affected ( > 0.05) by replacing soybean meal with peanut cake in the diet. Replacing soybean meal with peanut cake did not affect the pH ( = 0.79), color index ( > 0.05), and chemical composition ( > 0.05) of the meat (). However, a quadratic trend for the ash content was observed with peanut cake inclusion in the diet ( = 0.09). Peanut cake inclusion in the diet did not affect the concentrations of the sum of SFA ( = 0.29), the sum of unsaturated fatty acids (UFA; = 0.29), or the sum of PUFA ( = 0.97) or the SFA:UFA ratio ( = 0.23) in goat meat. However, there was a linear decrease ( = 0.01) in the sum of odd-chain fatty acids in the meat with increasing peanut cake in the diet. Soybean meal replacement with peanut cake did not affect the n-6:n-3 ratio ( = 0.13) or the

Govern-ment regulatory functions have great influence in regulating market behavior. Supervision of the industrial self-discipline organizations is the irreplaceable organic composition of market supervision. In order to ensure the sound operation of financial institutions, the government should strengthen internal control and risk management of the OTC derivatives market, improve the administrative supervision mechanism, improve the self-discipline ability of industrial associations, and especially, strengthen the risk supervision over off-balance-sheet activi-ties of financial institutions.

    This paper derives the impact of market integration on equilibrium firm size and market concentration in horizontally differentiated industries. We show that market concentration (measured by the number of firms) can rise as a consequence of market integration if firms engage in R&D competition. We also demonstrate that whether concentration occurs or not depends on the R&D production function and on consumer preferences. This result implies that the welfare effects of market integration are ...

    Two-breed crossbreds of Montbéliarde and Holstein (MO × HO) as well as 3-breed crossbreds of Montbéliarde and Jersey/Holstein (MO × JH) were compared with pure Holstein (HO) cows for production, somatic cell score (SCS), fertility, survival to subsequent calving, mortality, and body measurements during their first 5 lactations. Cows calved for the first time between 2005 and 2010 and were housed in either a confinement herd or a herd that had access to pasture for 165d of the year in the north central region of the United States. Body, hoof, and udder measurements of cows were also objectively measured. The MO × HO crossbred cows were not different from pure HO cows for fat-plus-protein production during any lactation. However, the MO × JH crossbred cows had 5% lower fat-plus-protein production compared with pure HO cows in the confinement herd. On the other hand, the MO × JH crossbred cows were not different for fat-plus-protein production in the third to fifth lactation compared with pure HO cows in the seasonal pasture herd. Across the 2 herds, the MO × HO and MO × JH crossbred cows had 21% higher first-service conception rate, 41 fewer days open, and 12% higher pregnancy rate compared with the pure HO cows. Furthermore, the MO × HO (5%) and MO × JH (12%) crossbred cows had lower mortality rates than the pure HO cows (18%). Because of superior fertility and lower mortality rates, the MO × HO and MO × JH crossbred cows, combined, had greater survival to second (+13%), third (+24%), fourth (+25%), and fifth (+17%) lactation compared with pure HO cows. For body measurements, MO × HO were similar to pure HO cows for hip height and heart girth, but MO × HO cows had more body condition and greater body weight (+39kg) across the first 5 lactations. The MO × JH cows had more body condition but 5cm shorter hip height and 28kg less body weight than pure HO cows across the first 5 lactations. Foot angle was steeper and hoof length was shorter for MO × HO

    Eighteen cross-bred buffaloes (F 1 , local breed x Murrah) and 19 cross-bred cows (F 1 , local breed x Holstein Friesian), 4-6 years of age, were used in the study to determine the potential of milk progesterone measurement as an aid in characterizing the onset of postpartum ovarian activity and for early pregnancy diagnosis. The first oestrous cycle, based on milk progesterone, commenced between days 40-50 postpartum in 17% of the buffaloes but between days 25-35 postpartum in 21% of the cows. At days 61-100 postpartum, 33% of the buffaloes had cycling ovaries with progesterone concentrations of 3.23-4.02 ng/mL, while 53% of the cows had cycling ovaries during the same period with progesterone concentrations of 3.52-4.16 ng/mL. During the oestrous cycle, the progesterone level showed peak elevations on day 15 in buffaloes and on day 9 in cows. The milk progesterone profiles of the buffalo took longer to reach peak levels, but declined faster than those in the cow. The accuracy of positive pregnancy diagnosis was 78% in buffaloes and 83.3% in cows, but the accuracy of diagnosing non-pregnancy was 100% in both species. (author). 4 refs, 2 figs, 1 tab

    Full Text Available Four crossbred cows with mummified fetus were utilized for the study. The cows weresubjected togynecologicalexamination and based on the findings the cases were diagnosed asmummified fetus. The cows were treated with 2 mg estradiol valerate and 500 μg cloprostenoland were examined every 12 hr after 24 hr of the treatment for cervical dilatation and othersigns related to fetal expulsion. The time duration between treatment and starting of cervicaldilatation ranged from 48 to 58h (53.00 ± 2.08 hr. Complete dilatation of cervix was observedafter 70.00 ± 2.94 hr post treatment (Range = 64-76 hr. The mean fetalcrown-rump length(CRL was 31.5 cm, which ranged from 27.5 to 38 cm. The number of cotyledons in pregnanthorn also showed wide variation (Range 24-38 numbers with mean ± SE of 30.3 ± 3.07numbers. In the placenta of three animals irregular shaped large adventitious cotyledons wereobserved in the inter-cotyledonary areas. Out of the four animals treated, three animals wereconceived within three estrous cycles and one animal had cystic ovary in the next cycle and wasnot conceived even after four cycles. It was concluded that the estradiolandprostaglandin F2α(PGF2αcombinationtherapy was effective for expulsion of mummified fetus in crossbred cowswithout affecting much on future fertility.

    Full Text Available The aim of the study was to compare the physical and chemical composition of the raw milk of crossbred cows in different production levels and influence of parity order and stage of lactation on milk chemical composition of high producing cows. The search was conducted in the municipality of Rio Verde in southwestern Goiás, 784 samples were collected from raw milk of crossbred cows in experiment I and were divided into three levels of production. In the second experimental procedure, the samples resulted in 657 samples of raw milk, being divided into 4 stages of lactation stage of the cows and divided into eight parity order in which first-calf heifers corresponded to first order, and multiparous cows from the second until the eighth creates. For analysis of variance and mean comparison was used lineation all casualized and we used the Tukey test at 5% probability, using the software SISVAR. The different levels of production resulted in physico-chemical differences of the constituents of milk, thus the percentages found may be related not only the level but also at the stage of lactation and parity order of the animals.

    The size, support, and health of udders limit the productive life of beef cows, especially those with background, because, in general, such cows have a reputation for problems with udders. Genomic association studies of bovine udder traits have been conducted in dairy cattle and recently in Continental European beef breeds but not in cows with background. The objective of this study was to determine associations of SNP and udder support scores, teat length, and teat diameter in half (Nellore), half (Angus) cows. Udders of cows ( = 295) born from 2003 to 2007 were evaluated for udder support and teat length and diameter ( = 1,746 records) from 2005 through 2014. These included a subjective score representing udder support (values of 1 indicated poorly supported, pendulous udders and values of 9 indicated very well-supported udders) and lengths and diameters of individual teats in the 4 udder quarters as well as the average. Cows were in full-sibling or half-sibling families. Residuals for each trait were produced from repeated records models with cow age category nested within birth year of cows. Those residuals were averaged to become the dependent variables for genomewide association analyses. Regression analyses of those dependent variables included genotypic values as explanatory variables for 34,980 SNP from a commercially available array and included the genomic relationship matrix. Fifteen SNP loci on BTA 5 were associated (false discovery rate controlled at 0.05) with udder support score. One of those was also detected as associated with average teat diameter. Three of those 15 SNP were located within genes, including one each in (), (), and (). These are notable for their functional role in some aspect of mammary gland formation or health. Other candidate genes for these traits in the vicinity of the SNP loci include () and (). Because these were detected in Nellore-Angus crossbred cows, which typically have very well-formed udders with excellent support

    Full Text Available The present experiment was conducted to evaluate the effect of simulated heat stress on digestibility and methane (CH4 emission. Four non-lactating crossbred cattle were exposed to 25°C, 30°C, 35°C, and 40°C temperature with a relative humidity of 40% to 50% in a climatic chamber from 10:00 hours to 15:00 hours every day for 27 days. The physiological responses were recorded at 15:00 hours every day. The blood samples were collected at 15:00 hours on 1st, 6th, 11th, 16th, and 21st days and serum was collected for biochemical analysis. After 21 days, fecal and feed samples were collected continuously for six days for the estimation of digestibility. In the last 48 hours gas samples were collected continuously to estimate CH4 emission. Heat stress in experimental animals at 35°C and 40°C was evident from an alteration (p<0.05 in rectal temperature, respiratory rate, pulse rate, water intake and serum thyroxin levels. The serum lactate dehydrogenase, aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase activity and protein, urea, creatinine and triglyceride concentration changed (p<0.05, and body weight of the animals decreased (p<0.05 after temperature exposure at 40°C. The dry matter intake (DMI was lower (p<0.05 at 40°C exposure. The dry matter and neutral detergent fibre digestibilities were higher (p<0.05 at 35°C compared to 25°C and 30°C exposure whereas, organic matter (OM and acid detergent fibre digestibilities were higher (p<0.05 at 35°C than 40°C thermal exposure. The CH4 emission/kg DMI and organic matter intake (OMI declined (p<0.05 with increase in exposure temperature and reached its lowest levels at 40°C. It can be concluded from the present study that the digestibility and CH4 emission were affected by intensity of heat stress. Further studies are necessary with respect to ruminal microbial changes to justify the variation in the digestibility and CH4 emission during differential heat stress.

    Full Text Available Extending the application of marketing science specific concepts and principles in various sectors would not have been possible without their gradual evolution, in terms of customization and differentiation tailored for a specific field. This phenomenon regarding marketing evolution in terms of both extensively and intensively way, led to the emergence and consolidation of a set of concepts adapted also for cultural products and services market, or in other words for culture “consumption”. This article highlights a number of marketing communications specific elements, derived from the peculiarities of modern culture consumer and the latest technologies interference in the creation and delivery of cultural products and services. Given the high degree of consumer involvement in relation to the needs that underlie consumption of cultural products and services, as well as the dimension specific for an artistic act in some cases, marketing communications has to respond to particular challenges in the process of building customer-provider relationship.

    Full Text Available The objective of this study was to produce milk powder from Ettawa-crossbred goat milk and subsequently evaluate the quality of the products. The raw material used was Ettawa-crossbred goat fresh milk with total solid, lactose, fat, and protein content of 15.93%, 4.2%, 4.8% and 4.7%, respectively. Milk with final total solid of 17.5% and 20% were prepared for spray drying by adding skim milk powder. Drying was carried out using a spray dryer type Lamp having nozzle size of 0.05 mm with an inlet temperature of 90°C and an outlet temperature of 45°C. Parameters observed were chemical, physical and microbiological qualities. The data showed that milk powder produced from Ettawa-crossbred goat milk had water content of 1.5-1.7%. Further analysis showed that the acidity, proteins, lactose, and fat content were 0.90%, 28.4%, 21.7%, and 22.5%, respectively. The physical analysis showed that milk powder produced from Ettawa-crossbred goat milk had a higher wettability score (143 seconds as compared to that of commercial products (29 seconds, a higher sieve test score (0.6 g vs 0.004 g, but similar index of insolubility (1.4 ml vs.1.6 ml. The microbiological analysis showed that the Total Plate Count (TPC, Enterobacteriaceae (EB and presumptive coliforms increased during storage either in refrigerator or room temperature. The increase in TPC, EB and coliforms was substantially higher when products were kept at room temperature than in refrigerator. In conclusion, Ettawa-crossbred goat milk powder had a good nutrition quality, but still need improvement for the physicochemical characteristic including wettability and nutritional enrichment for vitamins and minerals by means of fortification.

    The objective of this study was to evaluate growth at fattening, carcass characteristics and carcass measurements of 19 Sardi, 19 D'man and 52 meat-sire crossbred lambs of both sexes slaughtered at 50 and 70 % of mature weight. Crossbred lambs were born from Sardi, D'man and F1 Sardi × D'man ewes mated to meat-breed rams (Ile de France and Mérinos Précoce). Lambs of each group (breed type by sex) were chosen at random and slaughtered either at 50 or 70 % of mature weight. Sardi and D'man purebred lambs had significantly lower growth at fattening, pre-slaughter live weight, empty body weight, hot carcass weight, carcass conformation, carcass fatness, red offal, white offal, sub-products and non-carcass fat than meat-sire crossbred lambs. Differences were 42.2 g/day, 5.03 kg, 4.46 kg, 2.57 kg, 0.96, 0.59, 0.18 kg, 0.39 kg, 0.63 kg and 0.12 kg, respectively. B and Wr measurements of meat-sire crossbred lambs were higher than those of Sardi and D'man purebred lambs, whereas the F measurement was in favour of purebreds. Likewise, CC, G/F and Wr/Th indices of meat-sire crossbreds were higher than those of purebreds; however, the opposite was observed for L/G and Th/G indices. Maternal heterosis was positive and not significant for most traits, negative and not significant for few traits (P > 0.05), but negative and significant for the proportion of sub-products (P carcass characteristics of local sheep can be significantly improved by terminal crossbreeding.

    Full Text Available An experiment was carried out to estimate the genetic group effects and the crossbreeding genetic parameters of slaughter and carcass traits using data on the rabbits that were progeny of does coming from a full diallel cross between 4 maternal lines (A, V, H and LP mated to bucks of the paternal line R. The rabbits of the 16 genetic groups, corresponding to the type of does of the diallel cross, were distributed in 4 Spanish farms and 1 genetic group (V line was present in all farms in order to connect records among them and to be used as reference group. Crossbreeding parameters were estimated according to Dickerson’s model. 1896 rabbits were measured for slaughter traits and 950 for carcass traits. The A and LP lines had the lowest values for dressing percentage (–1.71 and –1.98 compared with H line and –1.49 and –1.75 with the V line, respectively. The A line was the heaviest for commercial carcass weight. No relevant differences were observed between the crossbred groups for all traits. Regarding the reciprocal effects, there were significant differences in favour of A line as sire line in the crossbred AV. Regarding the combination of direct and maternal effects, the A line showed significantly higher values for cold carcass weight (133 g., 71 g. and 142 g. compared to the H, LP and V lines. For the same parameter the H line showed significantly higher averages on dressing percentages than A and LP lines, 1.44 and 2.13%, respectively. Line A also showed, in general, better direct- maternal effects than the V line. Grand-maternal effects were less important than direct-maternal ones. The estimates of maternal heterosis were, in general, negative, which could be a consequence of the positive heterosis for litter size. However, despite this relationship between growth and litter traits, it has not been common to find negative maternal heterosis in growth traits. A diminution of dressing percentage was detected in

    2006-07-01

    Full Text Available Thirty crossbred (Sahiwal x Friesian male calves of 9-10 months age and weighing 70 to 90 kg, were used in completely randomized design to investigate the possibility of replacing cottonseed cakes (CSC with sunflower meal (SFM, partially or completely, in rations for fattening of crossbred calves for meat production. Three concentrate rations viz. A, B and C were formulated. Ration A containing CSC was fed to the calves of group A, ration B containing SFM was fed to calves of group B and ration C containing both CSC + SFM was fed to calves of group C. The feed intake of calves belonging to group C was the highest (5.7 ± 2.3 kg followed by group B (5.5 ± 1.3 kg and group A (5.2 ± 2.0 kg. Average daily body weight gain was 0.73 ± 0.1, 0.72 ± 0.2 and 0.71 ± 0.1 kg for groups A, B and C, respectively. Calves fed SFM gained numerically less than the calves fed CSC but higher than SFM+ CSC. Feed conversion ratio was 7.1 ± 0.4, 7.7 ± 0.7 and 8.0 ± 0.6, for calves of groups A, B and C, respectively. Dressing percentage averaged 51.5 ± 1.3, 52.1 ± 1.2 and 52.3 ± 0.8 for the respective rations. However, the differences in feed intake, daily weight gain, feed conversion ratio and dressing percentages among calves of three groups were non significant. Considering the cost of feed and average growth, the cost of per kg body weight gain was 38, 30 and 37 rupees for the groups A, B and C, respectively. The lowest cost was observed in SFM based ration (B that was about 19% less than ration containing CSC. Results indicated that for fattening of crossbred calves the use of SFM is as efficient as CSC but more economical and can successfully replace CSC in fattening rations.

Feed intake data for 106 finishing pigs between 140 and 210 d of age and the resulting weights and feed conversion ratios were analyzed by breed type. Least square means for body weights (birth, weaning and to 240 d were estimated with Proc Mixed in SAS 9.2 for fixed effects such as crossbreed and days of age within the sire breed. The differences within fixed effects were compared using least significant differences with DIFF option. Individual birth weights and weaning weights were influenced by sire breed (p<0.05. For birth weight, BY pigs were the lightest, TY and YY pigs were the heaviest but similar to each other and LBY pigs were intermediate. For weaning weights, BY and LBY pigs were heavier than TY and YY pigs. However, litter birth and weaning weights were not influenced by sire breed, and average daily gain was also not significantly different among breed types. Tamworth sired pigs had lower overall body weight gain, and feed conversion was lower in TY and YY groups than BY and LBY groups (p<0.05, however, number of observations was somewhat limited for feed conversion and for Tamworth pigs. Overall, no convincing differences among breed types were noted for this study, but growth performance in

    Cattle are an integral part of the largely agrarian economy of India. Indigenous breeds of cattle comprise about 80% of total cattle population of the country and contribute significantly to the overall milk production. There are 40 recognized indigenous breeds of cattle and a number of uncharacterized non-descript cattle. Pahari cattle of Himachal Pradesh in Northern India are one such non-descript indigenous breed. Here we describe a comprehensive evaluation of haematobiochemical parameters and innate and adaptive immune response traits of Pahari cattle and a comparison with Jersey crossbred cattle. The study shows demonstrable differences in the two breeds with respect to some innate and adaptive immunological traits. This is a first attempt to characterize immune response traits of Pahari cattle and the results of the study provide an understanding of breed differences in immune status of cattle which could be useful for their breeding and conservations programs.

    Full Text Available Objective An experiment was conducted to examine the effect of dietary supplementation of dried and ground foliage of black gram (Vigna mungo L. on feed intake and utilization, and production performance of crossbred lactating cows. Methods Eighteen lactating crossbred (Bos taurus×Bos indicus cows (body weight 330.93± 10.82 kg at their second and mid lactation (milk yield 6.77±0.54 kg/d were randomly divided into three groups of six each in a completely randomized block design. Three supplements were formulated by quantitatively replacing 0, 50, and 100 per cent of dietary wheat bran of concentrate mixture with dried and ground foliage of black gram. The designated supplement was fed to each group with basal diet of rice straw (ad libitum to meet the requirements for maintenance and milk production. Daily feed intake and milk yield was recorded. A digestion trial was conducted to determine the total tract digestibility of various nutrients. Results The daily feed intake was increased (p0.05, the fibre digestibility was increased (p0.05 among the groups, milk yield was increased by 10 per cent with total replacement of wheat bran in concentrate mixture with of black gram foliage. The economics of milk production calculated as feed cost per kg milk yield (INR 10.61 vs 7.98 was reduced by complete replacement of wheat bran with black gram foliage. Conclusion Black gram foliage could be used as complete replacement for wheat bran in concentrate mixture of dairy cows in formulating least cost ration for economic milk production in small holders’ animal production.

    Full Text Available The objective of the present study was to evaluate the effect of the use of babassu mesocarp meal (BMM and corn in different physical forms on the feeding behavior of crossbred young bulls of a dairy breed. Twenty-four crossbred (Nellore vs. Holstein steers (307.35 kg were fed four experimental diets containing two levels of inclusion of the babassu mesocarp meal (0 and 412.4 g/kg and corn in two physical forms (kernels or ground for 98 days. Data was collected on three days during the finishing phase, with observations every five minutes, for 24 hours. When the activities performed by the animals were evaluated as a function of the period of the day, the physical form of the corn showed interaction with the BMM inclusion level on the time spent feeding and on other activities. When the activities were evaluated over the day, the defecation frequency was affected and decreased as BMM was included. The feeding time was longer at the moments that followed feed supply, whereas the time used for other activities increased during the morning period, regardless of the diet utilized. Rumination and idle times were affected by the period of the day and remained high during the night and morning periods. There was increase in feeding time and dry matter rumination efficiencies and neutral detergent fiber as BMM was added to the diet. The number of rumination chews per bolus, however, decreased as BMB was included. Inclusion of babassu mesocarp meal increases the animal feeding time but the physical form of corn does not change its feeding behavior.

    The studies were conducted to elucidate the effect of feeding aflatoxin on nitrogen kinetics in rumen fistulated calves. One calf each in groups 1, 2, 5 and 6 and one bufffalo calf each, in groups 3, 4, 7 and 8 were alloted. Calves of groups 5 to 8 were provided optimum protein (OP) while those in groups 1 to 4 were given 42.5 per cent more protein (HP) in their diets. In addition, animals in groups 2, 4, 6 and 8 were given an oral dose of aflatoxin at the rate of 1.0 ppm of drymatter intake. Subsequent to digestibility trial, 2 hourly feeding was practised for 10 days, after which 15 N-ammonium sulphate and 51 Cr-EDTA were infused intra-ruminally. Results indicated that there was no effect of feeding aflatoxin on the digestibility of nutrients except crude protein. Nitrogen balances were better with groups fed OP diets as compared to HP diets, more in crossbreds than the buffalo. The estimated rumen volume ranged from 37.70 to 56.00 litres and rumen fluid outflow rates varied from 87.34 to 123.70 litres per day. Ruminal ammonia pool size, ruminal ammonia entry rates and irreversible loss rates were higher in HP fed groups without showing any effect of afflatoxins. Ruminal ammonia-N was better utilized for incorporation into bacterial protein and for transfer to plasma urea-N with OP fed groups, again without showing aflatoxin toxicity effect. Ruminal ammonia-N excretion pattern through urine was greater as a result of aflatoxin toxicity, more in crossbreds as compared to buffalo. (author). 19 refs. 5 tabs

Para tanto, um questionário foi aplicado a uma amostra de produtores de soja, sendo também entrevistados representantes de tradings, armazéns gerais, cooperativas, corretoras e agentes financeiros. Constatou-se que a utilização de ferramentas de proteção de preço é ainda pouco expressiva, já que apenas 11% dos produtores usam o Mercado Futuro (hedge e o Mercado de Opções, e 38% os utilizaram alguma vez. O principal mecanismo usado é o Mercado a Termo. Produtores que já usaram o Mercado Futuro (hedge e o de opções atuam em médias e grandes propriedades, têm nível de escolaridade alto e estão mais capitalizados. A baixa utilização dos derivativos (Futuros e Opções se dá, principalmente, pela falta de conhecimento e pela ausência de profissionais de confiança capazes de orientar os produtores.The present research analysed the behavior of the soybean farmer of Maracaju-MS, Brazil in relation to price risk and use of agricultural derivatives, seeking to identify the price protection mechanisms used and the reasons for their use or rejection. A questionnaire was applied to a sample of soybean farmers. Also, representatives of trading houses, storage plants, cooperatives, brokers and financial agents were interviewed. Results showed that the use of price protection tools is still scarce, as only 11% of farmers use future market price (hedge and the options market, and 38% have used them before. The main mechanism used is the forward market. Farmers who already have used futures market (hedge and options manage medium and large properties, have a high level of education and are better capitalized. The low use of derivatives (futures and options is mainly due to the lack of

    Objectives were to compare parameters related to innate immune responses and somatotropic axis of Holstein (HO) and Montbéliarde (MO)-sired crossbred cows during the transition from late gestation to early lactation. Cows (40 HO and 47 MO-sired crossbred) were enrolled in the study 45d before expected calving date (study d 0=calving). Polymorphonuclear leukocytes (PMNL) isolated from blood samples collected weekly from study d -7 to 21 and on study d 42 were used for determination of percentage of PMNL positive for phagocytosis (PA+) and oxidative burst (OB+), intensity of PA and OB, percentage of PMNL expressing CD18 (CD18+) and L-selectin (LS+), and intensity of CD18 and LS expression. Blood was sampled weekly from study d -7 to 14 and on study d 28, 42, and 56 for determination of insulin, growth hormone (GH), leptin, and insulin-like growth factor (IGF)-1 concentrations. Blood sampled weekly from study d -14 to 21 and on study d 42 was used to determine cortisol concentration. Liver biopsies were performed on study d -14, 7, 14, and 28 for determination of mRNA expression for insulin receptor B (IRB), total GH receptor (GHRtot), GHR variant 1A (GHR1A), and IGF-1. Data were analyzed by ANOVA for repeated measures or by ANOVA using the GLM procedure of SAS (SAS Institute Inc., Cary, NC). Intensity of CD18 expression was greater in PMNL from crossbred cows compared with PMNL from HO cows [1,482.1 ± 82.3 vs. 1,286.6 ± 69.8 geometric mean fluorescence intensity (GMFI)]. Furthermore, among HO cows, the percentage of PA+ PMNL on study d -7 (64.4 ± 5.2%) tended to be greater than on study d 0 (57.1 ± 5.1%), but no differences in percentage of PA+ PMNL between study d -7 and 0 were observed in crossbred cows. Similarly, intensity of PA in PA+ PMNL from HO cows decreased from study d -7 to 0 (4,750.6 ± 1,217.0 vs. 1,964.7 ± 1,227.9 GMFI), but no changes in intensity of PA in PA+ PMNL from crossbred cows were observed. On study d 0, intensity of PA tended to be

    Full Text Available Aim: A comparative study was conducted on crossbred cattle and buffaloes to investigate the effect of feeding high and low roughage total mixed ration (TMR diets on rumen metabolites and enzymatic profiles. Materials and Methods: Three rumen-fistulated crossbred cattle and buffalo were randomly assigned as per 3x3 switch over design for 21-days. Three TMR diets consisting of concentrate mixture, wheat straw and green maize fodder in the ratios of (T1 60:20:20, (T2 40:30:30, and (T3 20:40:40, respectively, were fed to the animals ad libitum. Rumen liquor samples were collected at 0, 2, 4, 6, and 8 h post feeding for the estimation of rumen biochemical parameters on 2 consecutive days in each trial. Results: The lactic acid concentration and pH value were comparable in both species and treatments. Feed intake (99.77±2.51 g/kg body weight, ruminal ammonia nitrogen, and total nitrogen were significantly (p0.05 among treatments and significantly (p<0.05 greater in crossbred cattle than buffaloes. Molar proportions of individual VFAs propionate (C3, propionate:butyrate (C3:C4, and (acetate+butyrate:propionate ([C2+C4]:C3 ratio in both crossbred cattle and buffalo were not affected by high or low roughage diet, but percentage of acetate and butyrate varied significantly (p<0.05 among treatment groups. Activities of microbial enzymes were comparable among species and different treatment groups. A total number of rumen protozoa were significantly (p<0.05 higher in crossbred cattle than buffaloes along with significantly (p<0.05 higher population in animal fed with high concentrate diet (T1. Conclusion: Rumen microbial population and fermentation depend on constituents of the treatment diet. However, microbial enzyme activity remains similar among species and different treatments. High concentrate diet increases number of rumen protozoa, and the number is higher in crossbred cattle than buffaloes.

    2006-11-13

    The Food and Drug Administration (FDA) is further delaying, until December 1, 2008, the applicability date of a certain requirement of a final rule published in the Federal Register of December 3, 1999 (64 FR 67720) (the final rule). The final rule implements the Prescription Drug Marketing Act of 1987 (PDMA), as modified by the Prescription Drug Amendments of 1992 (PDA), and the Food and Drug Administration Modernization Act of 1997 (the Modernization Act). The provisions of the final rule became effective on December 4, 2000, except for certain provisions whose effective or applicability dates were delayed in five subsequent Federal Register notices, until December 1, 2006. The provision with the delayed applicability date would prohibit wholesale distribution of blood derivatives by registered blood establishments that meet the definition of a "health care entity." In the Federal Register of February 1, 2006 (71 FR 5200), FDA published a proposed rule specific to the distribution of blood derivatives by registered blood establishments that qualify as health care entities (the proposed rule). The proposed rule would amend certain limited provisions of the final rule to allow certain registered blood establishments that qualify as health care entities to distribute blood derivatives. In response to the proposed rule, FDA received substantive comments. As explained in the SUPPLEMENTARY INFORMATION section of this document, further delaying the applicability of Sec. 203.3(q) (21 CFR 203.3(q)) to the wholesale distribution of blood derivatives by health care entities is necessary to give the agency additional time to address comments on the proposed rule, consider whether regulatory changes are appropriate, and, if so, to initiate such changes.

  5. Study of Blood Metabolites Changes of Purebred Ghezel and Crossbred Arkhar Merinos × Ghezel Ewes during Late Pregnancy

    2016-11-01

    Full Text Available Introduction As pregnancy progresses, nutrient requirements of fetus and thereby ewe increases and some changes in the levels of blood metabolites including glucose, cholesterol and total protein may occur. During gestation, maternal tissues contribute to supplying energy that required for fetus resulting in changes of ewe blood metabolites; however other factors such as breed, age, feeding type of ewes during gestation and season may influence them. The study of blood metabolic changes in different phases of reproductive cycle can be helpful in detecting abnormal situations of ewes and preventing of metabolic disorders such as pregnancy toxemia and fatty liver syndrome. There is little information about the effect of different genotypes on blood metabolites and the occurrence of metabolic disorders in late pregnancy. Therefore the aim of the present study was to determine changes in blood metabolites of purebred Ghezel and ArkharMerino× Ghezel crossbred ewes during late pregnancy and effect of crossbreeding of Iranian purebred sheep with Merino sheep on metabolite level changes in these two groups of sheep and study of susceptibility to metabolic disease in late pregnancy. Materials and Methods In the present study, fifty five pregnant Ghezel ewes (36 singles and 15 twins and 34 pregnant crossbred ewes (20 singles and 14 twins were used. Estrus synchronization of all ewes was done using CIDR. CIDR were removed 14 days later and all ewes were injected PMSG intramuscularly and then mated with rams. All of the ewes were grazing in the pasture during pregnancy, but in the last two months of pregnancy, feeding of ewes was manually. Blood samples were collected by vacuum tubes during four hours after feeding from the jugular vein of ewes on 15 days prior to mating period and on days 90, 120 and 140 of the pregnancy. Blood samples were centrifuged with 4000 rpm for 12 minutes to extract blood serum and then sera were frozen in -20oC until further

    (production d'alcools gras. Les chiffres d'affaires pour ces 3 catalyseurs sont respectivement égaux à 50,1, 0,5 et 11 millions de dollars/an. Since Institut Français du Pétrole (IFP has a great deal of experience in the field of catalysts, particularly for hydrogenation, the Evaluation Department has made studies at various times to evaluate the potential markets. The analysis making up this article was made to determine the possible outlets for catalysts used for the hydrogenation of fats and oils. It covers the food industry, the hydrogenation of fatty acids of animal or vegetable origin, and the production of fatty alcohols and fatty amines. This market is over $60 million per year and corresponds to nearly 11,000 t/year of catalysts used. These figures include captive consumptions of catalysts produced by companies using them. This business turnover is about the same as the one for hydrogenation catalysts used for the synthesis of the major building-block petrochemicals. More than 64% of the applications have to do with the food industry, i. e. production of margarine and shortening, hydrogenation of salad oils and deep-frying oils in the United States. Whereas the consumption of catalysts used in lipochemistry is highly concentrated in the main industrialized regions (United States, Western Europe, Japan, that of the food industry is much more scattered. The three regions mentioned above account for less than 64% of world consumption. Estimated outlets represent annual business turnovers of $41 million for the food industry, $8. 3 million for the production of fatty acids, $11 million for the production of fatty alcohols, and $1. 3 million for the production of fatty amines. These hydrogenations are performed in the presence of supported nickel (food industry, production of fatty acids and secondary and tertiary amines or in the presence of Raney nickel (production of primary amines or, copper chromite (production of, fatty alcohols.

Materials and Methods: A total of 76 quarters of lactating HF crossbred (Bos indicus × Bos taurus cows (n=19 were monitored for body temperature (i.e., eye temperature and udder skin surface temperature (USST before milking using forward-looking infrared (FLIR i5 camera. Milk samples were collected from each quarter and screened for mastitis using Somatic Cell Count (SCC, Electrical Conductivity (EC, and California mastitis test. Thermographic images were analyzed using FLIR Quick Report 1.2 image analysis software. Data on body and USST were compiled and analyzed statistically using SPSS 16.0 and Sigmaplot 11. Results: The mean±standard deviation (SD body (37.23±0.08°C and USST (37.22±0.04°C of non-mastitic cow did not differ significantly; however, the mean USST of the mastitis-affected quarters were significantly higher than the body temperature and USST of unaffected quarters (p37.61°C. Conclusion: It is concluded that infrared thermal imaging technique could be used as a potential noninvasive, quick cowside diagnostic technique for screening and early detection of SCM and clinical mastitis in crossbred cows.

    Thermotolerance depends mainly on the health and immune status of the animals. The variation in the immune status of the animals may alter the level of tolerance of animals exposed to heat or cold stress. The present study was conducted to investigate the expression profile of two important nucleotide binding and oligomerization domain receptors (NLRs) (NOD1 and NOD2) and their central signalling molecule RIP2 gene during in vitro thermal-stressed bovine peripheral blood mononuclear cells (PBMCs) of native (Sahiwal) and crossbred (Sahiwal X HF) cattle. We also examined the differential expression profile of certain acute inflammatory cytokines in in vitro thermal-stressed PBMC culture among native and its crossbred counterparts. Results revealed that the expression profile of NOD1/2 positively correlates with the thermal stress, signalling molecule and cytokines. Present findings also highlighted that the expression patterns during thermal stress were comparatively superior among indigenous compared to crossbred cattle which may add references regarding the better immune adaptability of Zebu cattle.

    The objective of this study was to demonstrate differences in aspects of adipose tissue cellularity, lipid metabolism, and fatty and cholesterol composition in Angus and Brahman crossbred cattle. We hypothesized that in vitro measures of lipogenesis would be greater in three-fourths Angus progeny than in three-fourths Brahman progeny, especially in intramuscular (i.m.) adipose tissue. Progeny ( = 227) were fed a standard, corn-based diet for approximately 150 d before slaughter. Breed was considered to be the effect of interest and was forced into the model. There were 9 breed groups including all 4 kinds of three-fourths Angus calves: Angus bulls Angus-sired F cows ( = 32), Angus bulls Brahman-sired F cows ( = 20), Brahman-sired F bulls Angus cows ( = 24), and Angus-sired F bulls Angus cows ( = 20). There were all 4 kinds of three-fourths Brahman calves: Brahman bulls Brahman-sired F cows ( = 21), Brahman bulls Angus-sired F cows ( = 43), Brahman-sired F bulls Brahman cows ( = 26), and Angus-sired F bulls Brahman cows ( = 13). Additionally, F calves (one-half Brahman and one-half Angus) were produced only from Brahman-sired F bulls Angus-sired F cows ( = 28). Contrasts were calculated when breed was an important fixed effect, using the random effect family(breed) as the error term. Most contrasts were nonsignificant ( > 0.10).

    Ten female crossbred (Brown Swiss X Baladi) calves , 8 – 10 months old with average live body weight of 112 kg at the be ginning of experimental period were used to investigate the effect of olive pomace (OP) supplementation which contains phenolic compounds on oxidant and antioxidant agents and some blood constituents, and its relation with growth performance in heat stressed calves. The animals were maintained under hot summer environmental conditions, where, ambient temperature and relative humidity average d 37.48°C ± 0.32 and 64.58 % ± 0.77 , (equivalent to THI 91) during day, and 28.38 °C ± 0.22 and 78.23 % ± 0.69 , (equivalent to THI 80) during night, respectively. The animals were divided into two equal groups (5 calves each). The first group control (received 0 % OP of the concentrate mixture, while the second group) treated received 15 % OP of the concentrate mixture, for two months. Body weight o f calves was recorded twice at the beginning and at the end of experimental period, and daily gain was calculated for each animal. Blood samples were taken from each animal at the end of experimental period to determine antioxidant and oxidant indices, some blood constituents and T 3 concentration. Our results showed that supplementation of OP significantly increased antioxidant status including catalase enzyme activity, total antioxidant capacity, uric acid as a non-enzymatic antioxidant and copper as a specific antioxidant protecting macromolecules. More over, OP significantly reduced serum malondialdehyde as a lipid peroxidation marker, iron concentration which act as a pro-oxidant, lipids profile including total cholesterol, low density lipoprotein (LDL – cholesterol), very low density lipoprotein (VLDL – cholesterol), triglycerides and phospholipids. Also, OP caused a significant decrease in serum creatinine and urea- N concentrations as well as AST activity. However, OP significantly elevated T3 level, and improved feed efficiency and daily

    Full Text Available Abstract. A comparative analysis of amino acid composition of lamb meat from the North East Bulgarian fine fleece breed (I gr. and its crossbreds from internal breeding with 25% heredity from the Australian merino (II gr. and Ile de France (III gr. breeds was conducted. Upon starting the experiment lambs were equal and during the experiment they were placed under similar conditions of feeding and rearing. To establish the amino acid composition of meat slaughter analyses were performed at 100 and 130 days of age. From the carcass of each slaughtered animal individual mean samples were taken. Studies were carried out in the Research Laboratory of the Faculty of Agriculture at Trakia University. As a result of the studies the following conclusions were made: ¼ Ile de France crossbreds in a sophisticated crossing have the highest total amino acid content, including essential amino acids in the meat of 100- and 130-day-old lambs, 6.87% and 7.36%, respectively. The lysine/arginine ratio, relating to protein atherogenicity, varies within narrow ranges among groups and marks slight increase with age – from 1.31-1.37 at 100 days to 1.41-1.46 at 130 days. With the increase of age in crossbreds from internal breeding total protein amino acid content grows, that being most prominent in lambs from the III group – from 41.92 to 43.49%. The values of total protein indices increase compared to the reference protein (from 117.97% to 118.22% for II group and from 116.44% to 120.80% for III group and the whole egg protein (from 89.39% to 91.92% for II group and from 90.53% to 93.93 for III group. It has been found that internal breeding of crossbreds with 25% heredity from the Ile de France breed has positive effect concerning the total amino acid content of lamb meat at 100 and 130 days of age, essential amino acid content in it and the levels of total amino acid indices. Internal breeding of crossbreds with 25% heredity from the Australian merino breed

    Senator Lieberman and three fellow members of Congress introduced the CO 2 Offset Policy Efficiency Act (COPE), which incorporates the use of marketable permits to reduce CO 2 emissions. For COPE to be fully effective, however, several key criteria must be met: (1) establishing initial baselines will be critical to ensure that emission reductions are credited properly; (2) accurate plant-by-plant monitoring must be in place to ensure that claimed reductions have actually occurred; (3) the program must include a strong enforcement provision to prevent evasion and to punish violators with substantial automatic fines. COPE imposes a sanction equal to roughly four times the estimated cost of offsets; the sanctions would be paid before enforcement proceedings commence. The urgency and complexity of global warming requires us to break with the past and develop new ways of delaying with pollution, Senator Lieberman feels by giving the market a chance to work on behalf of the environment, the sale of emission allowance will reduce CO 2 emissions in the most-efficient cost-effective way possible

This study was conducted to investigate the natural B. bovis infection in water buffaloes in comparison to crossbred cattle under field conditions in Egypt.A total of 35 buffaloes and cattle were clinically and laboratory investigated from March to June 2008. Twenty-nine buffaloes and cattle out of 35 were naturally infected with B. bovis and showed signs of bovine babesiosis. Three cows and three buffaloes showed no clinical signs and were free from external, internal, and blood parasites served as control group.Babesia bovis-infected cattle showed typical signs of bovine babesiosis while B. bovis-infected buffaloes showed a milder form (less severe of the clinical signs. Advanced cases of cattle showed dark brown to dark red (coffee-color urine, hemoglobinuria and nervous manifestations while these manifestations were not detected in the infected buffaloes. Hematological changes in both species however, these changes were less significant in buffaloes than those reported in cattle.This paper documents the first description of natural B. bovis infection in water buffaloes which were found to be more likely to be tolerant than cattle to the natural clinical infection with B. bovis and its subsequent haematological changes. Our finding may lead to a better understanding of the disease pattern of B. bovis infection under field conditions in buffaloes.

    Evaluation of the effect of clinical mastitis (CM) and its treatment outcome on the reproductive performance in crossbred cows retrospectively. Datasets of 835 lactating cows affected with CM during a period of 12 years (2001-2012) were considered for this study. Mastitis treatment related data and reproductive parameters such as days to first detected heat (DTFDH), days to first insemination (DTFI), days open (DO), and number of services per conception (SC) were collected from mastitis treatment and artificial insemination registers, respectively. Data were analyzed by ANOVA using SPSS 20 software. The means were compared with the Duncan's multiple comparison post-hoc test. CM affected cows had significantly (p<0.05) higher DTFDH, DTFI, DO and SC compared to clinically healthy cows. Cows diagnosed with a single episode of CM had significantly (p<0.05) delayed DTFDH while, DO and SC were significantly higher (p<0.05) in cows diagnosed by multiple episodes of CM. SC was significantly (p<0.05) higher in cows diagnosed with both relapse and recurrence. Severe CM affected cows had significantly (p<0.05) altered reproductive parameters. The reproductive parameters were altered to high extent when CM occurred during the breeding period. CM-affected cows had higher DTFDH, DTFI, DO and SC compared to clinically healthy cows. The negative effects of CM on reproduction parameters were higher when CM occurred during the breeding period.

    Hybrid vigor or heterosis is the phenomenon where a crossbreed progeny has better performance compared to its parents. Heterosis can be quantified relative to the mid-parents value or relative to one of its parent’s population average by crossing two breeds. Crossbreeding is aimed to increase the production performance of local breeds. According to the Indonesian government policy, crossbreeding program is one of main strategies to achieve meat self-sufficiency. We explore the possibilities observing of heterosis exhibited by crossing Bali and Peranakan Onggole (PO) cattle as local breed with the exotic breed based on the published data. In this paper, growth and reproductive traits from Bali and PO from year 2000-2010 were used for analysis. Moreover, Limousine and Simmental exotic breed data were collected from official information of artificial insemination (AI) centre. Data in growth trait (chest girth, mature weight, weaning weight and yearling weight) in all breeds and their crosses were then analysed using standard heterosis estimation method. Result, shows that crossbred offspring perform better in the growth trait in relative to Bali and PO as local breed. Specifically in Bali crossed with PO, the offspring shown better estimated heterosis effect in yearling weight compared to both parents. Despite heterosis were observed in some traits, careful planning of crossbreeding program is a must in order to avoid the loss of genetic variance.

    Full Text Available The objective of this study was to investigate the effect of rapid chilling (RC on beef quality and the degradation of cytoskeletal proteins. Twenty Chinese Yellow crossbred bulls were selected and randomly divided into two groups. RC and conventional chilling (CC were applied to left and right sides of the carcasses respectively after slaughtering. To determine whether electrical stimulation (ES treatment can alleviate the potential hazard of RC on meat quality, ES was applied to one group. The effects of RC and ES were determined by meat color, shear force and cytoskeletal protein degradation postmortem (PM. The results showed that RC decreased beef tenderness at 1 d and 3 d postmortem, but had no detrimental effect on meat color. Western blotting showed that RC decreased the degradation rate of desmin and troponin-T, but the effects weakened gradually as postmortem aging extended. Degradation rates of both desmin and troponin-T were accelerated by ES. The combination of RC and ES could improve beef color, accelerate degradation rate of cytoskeletal protein and improve beef tenderness.

    2007-01-01

    This study reviews the developments in the onshore and offshore renminbi derivatives markets. The onshore market has seen a rapid build-up in the market infrastructure and price discovery mechanism in the past year, with empirical evidence suggesting that its pricing is increasingly determined by financial fundamentals, such as the covered interest rate parity. However, the growth of the market has been restrained by restrictions on the participant base, limited variations in the RMB/US$ exchange rate, market participants'lack of technical capacity and experience, and inadequate supporting financial market infrastructure. The non-deliverable forward (NDF) market, concentrated in Hong Kong and Singapore, is more developed, but has the drawback that its pricing is not tied to financial fundamentals. The comparison between onshore and offshore markets suggests that two issues are of particular importance for future derivatives market development in China: the balance between regulation and development, and the relationship between onshore and offshore markets.

    2000-01-01

    In the process of liberalization of the electricity market the customers are now in a position to participate in the decision on how their electricity is produced. In particular, many consumers have a preference for renewable energies. For the producers, marketing of 'eco-power' is an opportunity to achieve sustainable competitive advantage. However, the market share of these products is still quite small today, and 'eco-power' is usually marketed as an expensive niche product. From the perspective of sustainable development these niches are a necessary but not sufficient step. In this book, ways are discussed which could lead to a mass-market penetration of eco-power products. A theoretical analysis is combined with empirical evidence derived from the eco-power market in Germany, Switzerland, Great Britain and the U.S. as well as with a comparison with other market segments [de

  20. Market Access and Welfare

    DEFF Research Database (Denmark)

    Raimondos-Møller, Pascalis; Woodland, Alan D.

    According to the literature, well known tariff reform rules that are guaranteed to increase welfare will not necessarily increase market access, while rules that are guaranteed to increase market access will not necessarily increase welfare. Such conflict between welfare and market access...... objectives of trade policy is problematic and calls for finding alternative tariff reform rules that can achieve both objectives at the same time. The present paper contributes to this aim by using a new set of tariff reforms that are based on local optimality. Using such reforms it is shown that market...... access and consumer welfare will always be weakly compatible, in the sense that reforms based on each objective have the same signed effect on the other objective. For strong compatibility, whereby both objectives increase as a result of a locally optimal tariff reform, we derive both a necessary...

    Bioeconomic models were developed to calculate economic values (EV) for economically important traits in beef cattle, to evaluate the impact of these traits on production profitability, to assess possible market changes with a payment system and to develop economic selection indexes for Angus cattle for two production systems. Two beef cattle production systems were simulated as follows: a cow-calf cycle (CC) and a complete cycle (CoC). Following selection, positive changes in the EV were observed. In the CC, each 1.0% increment in weaning weight (WW), weaning rate (WR) and pregnancy rate (PR) resulted in increases in US$ 1.30, US$ 3.68 and US$ 3.55 per cow/year in profit, respectively. In the CoC, EV of US$ 1.01, US$ 1.79, US$ 1.19, US$ 1.34, US$ 6.84 and US$ 7.86 per cow/year were obtained for WW, year weight, yearling weight, final weight, WR and PR, respectively. The payment system for carcass quality showed that the scenario considering that 100% of the animals displayed uniform carcasses exhibited the highest EV and was considered optimal. Considering the sensitivity analysis, the price paid per animal was the factor that most affected the EV in both systems. The selection indexes obtained may be used in similar production systems, and the use of EV and selection indexes are important tools for any production system with positive change in profit after selection. © 2018 Blackwell Verlag GmbH.

    Full Text Available Productivity of F1 crossbred ewes between the prolific D’man and the local Queue fine de l’Ouest breeds (D’man x QFO mated with terminal sires of the Brune noire de Suisse (BNS breed was evaluated and compared to that of (i QFO and D’man ewes respectively mated to rams of the same breed in a research station (ESAK and of (ii QFO ewes mated to rams of the same breed in a commercial farm (El-Mabrouka. In ESAK station, data collected between 1995 and 2003, and related to 343, 168 and 323 lambings of QFO, D’man, and F1 crosses D’man x QFO ewes, respectively, were used. At birth, the mean litter size was 1.17 ± 0.37, 1.76 ± 0.71, and 1.40 ± 0.54 for ewes of the QFO, D’man, and crosses D’man x QFO genotypes, respectively, whereas at 90 days after lambing, the corresponding figures were 1.13 ± 0.40, 1.65 ± 0.70, and 1.31 ± 0.54. The year of lambing, genotype of the ewe as well as their interaction were significant sources of variation of all litter sizes. At 10 days after lambing, the weight productivity of QFO ewes was 7.3 ± 2.5 kg, and was thus significantly higher (p < 0.05 than that of D’man (6.6 ± 2.7 kg, and D’man x QFO (7.0 ± 2.3 kg ewes. This trend was reversed 90 days after lambing with weight productivity of D’man x QFO, and D’man ewes reaching 22.9 ± 7.7 and 22.5 ± 12.0 kg, respectively, and that of QFO sheep 19.5 ± 6.7 kg. With the exception of the age of the ewe, all other sources of variation highly influenced (p < 0.001 most weight productivity traits. In El-Mabrouka farm, the data used concerned 1048 and 529 lambings of QFO, and D’man x QFO breeds, respectively, that occurred during years 1999, 2000 and 2001. The year of lambing, genotype of the ewe as well as its age were highly significant sources of variation for the litter size at birth. Crossbred ewes produced on average 0.2 lamb more than QFOs (p < 0.05. Difference in productivity at 70 days after lambing was approximately 3 kg in favor of D

    Full Text Available ABSTRACT This study aimed to evaluate the buriti oil (Mauritia flexuosa L. inclusion levels (0, 15, 30, and 45 g kg−1 in dry matter replacing ground corn on the feeding behavior, as well as physiological and hematological variables of crossbred lactating Anglo Nubian goats. Eight Anglo Nubian goats were used, which were distributed in a double 4 × 4 Latin square experimental design (four periods and four levels of buriti oil replacing corn in the total dry matter. For the evaluation of feeding behavior, single animals were observed every ten minutes for 24 h on three days. Respiratory rate (RR, heart rate (HR, rectal temperature (RT, and sweating rate (SR of the animals were evaluated in the morning (09:00 h and in the afternoon (15:00 h. Blood samples were always taken in the morning, before feeding, by puncturing the jugular vein for the complete blood count and white blood cell count. The levels of buriti oil had no effect on feeding, rumination, idling time, water intake, defecation and urination, DM intake, feed efficiency, and rumination efficiency of DM and NDF, but had effects on NDF intake. Physiological variables (RT, SR, RR, and HR in both periods of the day were not influenced by the inclusion of buriti oil. However, SR and RR were higher in the afternoon than in the morning. In erythrocyte, results showed that the hematocrit and mean corpuscular volume increased with the inclusion of buriti oil. Hemoglobin, red blood cell count, mean corpuscular hemoglobin concentration, and total plasma protein were not affected by the inclusion of buriti in the goat diet. The inclusion of buriti oil is recommended in up to 45 g kg−1 (DM basis as a replacement for ground corn in diet of lactating goats without affecting the feeding behavior and physiological and hematological variables.

    The objective of this study was to characterize breeds representing diverse biological types for birth and weaning traits in crossbred cattle (Bos taurus). Gestation length, calving difficulty, percentage of unassisted calving, percentage of perinatal survival, percentage of survival from birth to weaning, birth weight, weaning weight, BW at 205 d, and ADG was measured in 1,370 calves born and 1,285 calves weaned. Calves were obtained by mating Hereford, Angus, and MARC III (1/4 Hereford, 1/4 Angus, 1/4 Pinzgauer, and 1/4 Red Poll) mature cows to Hereford or Angus (British breeds), Norwegian Red, Swedish Red and White, Wagyu, and Friesian sires. Calves were born during the spring of 1997 and 1998. Sire breed was significant for gestation length, birth weight, BW at 205 d, and ADG (P Angus cows had the shortest (282 d). Offspring from MARC III cows were the heaviest at birth (39.4 kg) when compared with offspring from Hereford (38.2 kg) and Angus (38.6 kg) cows. Progeny from Angus cows were the heaviest at 205 d (235 kg) and grew faster (0.96 kg/d), whereas offspring from Hereford cows were the lightest at 205 d (219 kg) and were the slowest in growth (0.88 kg/d). Sex was significant for gestation length (P = 0.026), birth weight, BW at 205 d, and ADG (P < 0.001). Male calves had a longer gestation length (284 d) when compared with female calves (283 d). Males were heavier than females at birth and at 205 d, and grew faster. Sire breed effects can be optimized by selection and use of appropriate crossbreeding systems.

    Full Text Available This study was conducted to observe the effects of crossbreeding and gender on the carcass traits and meat quality of Korean Native Black Pig (KNP and KNP×Duroc crossbred (KNP×D. A total of 50 pigs comprising seven KNP barrows, eight KNP gilts, twenty KNP×D barrows and fifteen KNP×D gilts were used in this study. Animals were reared in the same housing condition with same feed diet for six months prior to slaughter. After an overnight chilling, the carcasses were graded, and samples of Musculus longissimus dorsi were obtained for meat quality analysis. The slaughter and carcass weights and dressing percentage of KNP×D were higher (p<0.001 than those of KNP. The slaughter and carcass weights and backfat thickness of barrows were higher (p<0.01 than those of gilts. There were no significant difference in carcass conformation and quality grade between KNP and KNP×D as well as barrow and gilt. Fat content of KNP×D was higher (p<0.001 than that of KNP. Fat content of barrow was higher (p<0.001 than that of gilt. There was interaction between crossbreeding and gender on the fat content. KNP gilt showed higher fat content than KNP barrow whereas KNP×D barrow showed higher fat content than KNP×D gilt. Lightness, redness, yellowness, chroma and hue angle values and color preference of meat of KNP×D were lower (p<0.001 than those of KNP. Redness, yellowness and chroma values of meat of barrow were lower (p<0.05 than those of gilt. It is concluded that crossbreeding KNP with Duroc increases carcass productivity and meat fat but decreases meat color values and preference. Crossbreeding of KNP with Duroc produces a better fat deposition in meat of barrows than in gilts.

    Cattle resistance to ticks is measured by the number of ticks infesting the animal. The model used for the genetic analysis of cattle resistance to ticks frequently requires logarithmic transformation of the observations. The objective of this study was to evaluate the predictive ability and goodness of fit of different models for the analysis of this trait in cross-bred Hereford x Nellore cattle. Three models were tested: a linear model using logarithmic transformation of the observations (MLOG); a linear model without transformation of the observations (MLIN); and a generalized linear Poisson model with residual term (MPOI). All models included the classificatory effects of contemporary group and genetic group and the covariates age of animal at the time of recording and individual heterozygosis, as well as additive genetic effects as random effects. Heritability estimates were 0.08 ± 0.02, 0.10 ± 0.02 and 0.14 ± 0.04 for MLIN, MLOG and MPOI models, respectively. The model fit quality, verified by deviance information criterion (DIC) and residual mean square, indicated fit superiority of MPOI model. The predictive ability of the models was compared by validation test in independent sample. The MPOI model was slightly superior in terms of goodness of fit and predictive ability, whereas the correlations between observed and predicted tick counts were practically the same for all models. A higher rank correlation between breeding values was observed between models MLOG and MPOI. Poisson model can be used for the selection of tick-resistant animals. © 2013 Blackwell Verlag GmbH.

    Genetic correlations between performance traits with meat quality and carcass traits were estimated on 6,408 commercial crossbred pigs with performance traits recorded in production systems with 2,100 of them having meat quality and carcass measurements. Significant fixed effects (company, sex and batch), covariates (birth weight, cold carcass weight, and age), random effects (additive, litter and maternal) were fitted in the statistical models. A series of pairwise bivariate analyses were implemented in ASREML to estimate heritability, phenotypic, and genetic correlations between performance traits (n = 9) with meat quality (n = 25) and carcass (n = 19) traits. The animals had a pedigree compromised of 9,439 animals over 15 generations. Performance traits had low-to-moderate heritabilities (±SE), ranged from 0.07±0.13 to 0.45±0.07 for weaning weight, and ultrasound backfat depth, respectively. Genetic correlations between performance and carcass traits were moderate to high. The results indicate that: (a) selection for birth weight may increase drip loss, lightness of longissimus dorsi, and gluteus medius muscles but may reduce fat depth; (b) selection for nursery weight can be valuable for increasing both quantity and quality traits; (c) selection for increased daily gain may increase the carcass weight and most of the primal cuts. These findings suggest that deterioration of pork quality may have occurred over many generations through the selection for less backfat thickness, and feed efficiency, but selection for growth had no adverse effects on pork quality. Low-to-moderate heritabilities for performance traits indicate that they could be improved using traditional selection or genomic selection. The estimated genetic parameters for performance, carcass and meat quality traits may be incorporated into the breeding programs that emphasize product quality in these Canadian swine populations.

    This study compared the two breed groups of Girolando (½ Holstein ½ Gyr vs. ¾ Holstein ¼ Gyr) through analysis of the percentages (stressed or non-stressed cows) of rectal temperature (RT), respiratory rate (RR) and pregnancy rate (PR), and means of production and reproduction parameters to determine the group best suited to rearing in semiarid tropical climate. The experiment was conducted at the farm, in the municipality of Umirim, State of Ceará, Brazil. Two hundred and forty cows were used in a 2 × 2 factorial study; 120 of each group were kept under an intensive system during wet and dry seasons. The environmental parameters obtained were relative humidity (RH), air temperature (AT), and the temperature and humidity index (THI). Pregnancy diagnosis (PD) was determined by ultrasonography 30 days after artificial insemination (AI). The milk production of each cow was recorded with automated milkings in the farm. The variables were expressed as mean and standard error, evaluated by ANOVA at 5 % probability using the GLM procedure of SAS. Chi-square test at 5 % probability was applied to data of RT, RR, pregnancy rate (PR), and the number of AIs to obtain pregnancy. The majority of ½ Holstein cows showed mean values of RT and RR within the normal range in both periods and shifts. Most animals of the ¾ Holstein group exhibited the RR means above normal during the afternoon in the rainy and dry periods and RT means above normal during the afternoon in the dry period. After analyses, ½ Holstein crossbred cows are more capable of thermoregulating than ¾ Holstein cows under conditions of thermal stress, and the dry period was more impacting for bovine physiology with significant changes in physiological parameters, even for the first breed group. Knowledge of breed groups adapted to climatic conditions of northeastern Brazil can directly assist cattle farmers in selecting animals best adapted for forming herds.

    Full Text Available Aim: The current study aimed to compare the impact of heat stress (HS on some physiological functions and blood oxidative stress biomarkers between dry dairy crossbred (Balady X Friesian cows and buffaloes during Egyptian summer season (July-September. Materials and Methods: A total of 26 healthy animals were equally used in the in the current study. The criterion for cows and buffaloes selection and the management conditions were similar. A total mixed ration to meet the animal's requirements was used, and dry matter intake (DMI was calculated. Ambient temperature, relative humidity, temperature humidity index (THI, respiratory rate, and rectal temperature (RT were daily recorded. Meanwhile, live body weight and body condition score were weekly recorded. Blood samples were collected bi-weekly, and plasma samples were harvested for malondialdehyde (MDA content and enzymatic antioxidants such as glutathione peroxidase, superoxide dismutase, and catalase activities determinations throughout the experimental period (8 weeks - prepartum. Results: The results confirmed, the HS condition, as the THI values ranged from 79.74 to 90.4 throughout the experimental period. In both species, HS increased RT and decreased DMI (<10.5 kg/day and 9.5 kg/day in cows and buffaloes, respectively. Buffaloes seemed to be more affected by the hostile environmental condition of this study compared with their respective cows. Buffaloes had recorded up to 1 °C increase in their RTs in most of the point's period compared to cows. There was a continuous increase in MDA values (194.7 and 208.4 nmol/gHb in buffaloes and cows, respectively, 2 weeks prepartum as the animals come close to parturition with moderate decrements for the enzymatic antioxidant activities in both cows and buffaloes. Conclusion: It can be concluded that during Egyptian's summer season, HS had adversely affected feed intake and consequently animal's production performances.

    Jersey x Holstein crossbreds (JxH; n = 76) were compared with pure Holsteins (n = 73) for 305-d milk, fat, and protein production; conception rate; days open; proportion of cows pregnant within fixed intervals postpartum; and body and udder measurements during first lactation. Cows were housed at 2 research locations of the University of Minnesota and calved from September 2003 to May 2005. The JxH were mated to Montbeliarde sires, and Holstein cows were mated to Holstein sires. Best Prediction was used to determine actual production (milk, fat, and protein) for 305-d lactations with adjustment for age at calving, and records less than 305 d were projected to 305 d. The JxH (274 kg) and pure Holsteins (277 kg) were not significantly different for fat production, but JxH had significantly less milk (7,147 vs. 7,705 kg) and protein (223 vs. 238 kg) production than pure Holsteins. The JxH had significantly fewer days open than pure Holsteins (127 vs. 150 d). Also, a significantly greater proportion of JxH were pregnant at 150 and 180 d postpartum than pure Holsteins (75 vs. 59% and 77 vs. 61%, respectively). The JxH had significantly less body weight (60 kg) at calving, but significantly greater body condition (2.80 vs. 2.71). Furthermore, JxH had significantly less udder clearance from the ground to the bottom of the udder than pure Holsteins (47.7 vs. 54.6 cm), and greater distance between front teats (15.8 vs. 14.0 cm) than pure Holsteins during first lactation.

    The present study was conducted to know the smallholder pig production system in tribal areas of Sikkim State, India. Two hundred tribal farmers were selected randomly from the North and East District of the state. Information on socio-economic characteristics of farmers (gender, occupation, educational status, and farming experience), management practices, disease prevalence, and economics in pig production was collected. The study recorded the mean land holding as 1.2 ± 0.8 ha, and the number of pigs per farm was 5.0 ± 0.28. Pigs were mainly kept as a source of income, and 70 % of farmers reared crossbreed pigs. Ninety percent (90 %) of respondents practiced the intensive system of management whereby kitchen wastes along with cooked mixture comprising maize bhusa, mustard oil cake, pseudostem of banana, tuber, stem, and plant leaves were used to feed their animals. About 40.5 % of farmers procured their breeding stock from government farms that had good records and utilized veterinary services like timely vaccination and deworming. The diseases prevalent in the study area were swine fever, diarrhea, helminthoses, sarcoptic mange, pneumonia, etc. The litter sizes at birth (local, 4.3 ± 0.45; crossbreed, 7.2 ± 0.33), at weaning (local, 2.79 ± 0.24; crossbreed, 6.1 ± 0.21), and age at first farrowing (local, 365.39 ± 7.96 days; crossbreed, 337.24 ± 8.79 days) were recorded. Production costs of meat extracted from local and crossbred pigs were 1.08 $/kg and 0.86 $/kg, respectively.

    The experiment was conducted at Sekota District using 36 intact yearling males of pure Abergelle breed and Abergelle crossbred goats (50%) with a mean live weight of 18.92 ± 0.72 kg (mean ± SE). The objective of the experiment was to evaluate the effect of different levels of concentrate mixture supplementation on feed intake, live weight gain, and economic gain of the breeds. Goats were blocked based on initial body weight and were randomly assigned to the dietary treatments. The experimental design was a 2 × 3 factorial in RCBD (randomized complete block design). The treatments included ad libitum feeding of local grass hay and supplementation with three levels (184, 368, and 552 g/day) of concentrate mixture. The experiment consisted of 90 days of feeding. Daily, total dry matter and CP (crude protein) intakes were affected by diet and genotype (P < 0.01). Significant decrease (P < 0.001) in hay intake was observed as the level of the supplement increased. Besides, substitution rate increased with increasing levels of supplementation. Average daily body weight gains were significantly impacted only by diet. Animals fed on 184 significantly lower weights, while nonsignificant difference was observed in live weight gain between 368 and 552 supplemented group. Supplementation of 368 concentrate mix significantly improved (P < 0.05) feed intake, daily weight gain, and feed conversion efficiency. Supplementation of 368 g/day had showed significantly higher net return for both goat breeds. However, the Abergelle breed was significantly better in net profit and sensitivity than the crossbreed. Both genotypes performed better with the diet containing 368 g/day than that with 184 and 552 g/day of concentrate supplementation.

    2014-05-01

    The objectives of this work were to compare reproduction and parturition traits of the Criollo breed Romosinuano as straightbred and crossbred cows with Angus and Brahman, to estimate heterosis and direct and maternal genetic breed effects, and to describe calf loss, cow removals from the project, the occurrence of calving difficulty, inadequate calf vigor at birth, and udder problems by cow breed groups. Cows (n = 404) were born from 2002 to 2005. After their first exposure to bulls as young cows, in all subsequent breeding seasons crossbred cows were bred to bulls of the third breed, and straightbred cows were bred to bulls of the other two breeds. Calving records (n = 1,484) from 2005 to 2011 were used to create calving and weaning rate and calving interval (excluding the interval between 2 and 3 yr of age). Final models for these traits included sire breed-dam breed interaction, cow age within year, and random animal effects. Heterosis estimates for Romosinuano-Brahman calving and weaning rate were 0.06 ± 0.02 and 0.07 ± 0.03 (P Angus were twice as large (0.13 ± 0.03 and 0.14 ± 0.03, respectively; P Angus direct effects were beneficial for both traits (0.1 ± 0.05, P Angus, respectively (P Angus dams had the most occurrences of difficult births as a proportion of cows that calved (0.028 and 0.025, P = 0.04). Angus-sired crossbred cows and Brahman cows had the most occurrences of udder problems as a proportion of lactating cows (0.14 to 0.21, P Angus cow performance was acceptable, but for most traits, those pairs of breeds had lower heterosis than Brahman-Angus.

    Crossbred cows (n=80) resulting from the use of Jersey (JE) semen on their pure Holstein (HO) dams were compared with pure HO cows (n=77) for body weight, body condition score, fertility, and survival during their first 3 lactations. Cows were in 2 research herds of the University of Minnesota and calved from September 2003 to June 2008. The JE × HO crossbred cows had significantly less body weight during the first (-56 kg), second (-67 kg), and third (-82 kg) lactations than pure HO cows. However, JE × HO cows had significantly greater body condition score during the first (2.94 vs. 2.84), second (2.97 vs. 2.84), and third (2.99 vs. 2.87) lactations than pure HO cows. For fertility, JE × HO cows had fewer days to first breeding during the first (-10.6d), second (-8.4d), and third (-12.3d) lactations than pure HO cows. Crossbred cows were not significantly different from pure HO cows for number of services during first lactation; however, JE × HO cows had significantly fewer services (2.2) than pure HO cows (2.7) during the second lactation. Also, JE × HO cows had significantly fewer days open than pure HO cows in the first (-24 d), second (-42 d), and third (-42 d) lactations. For survival, JE × HO cows were not significantly different from pure HO cows for percentage of cows calving a second time; however, a tendency existed for a higher percentage of JE × HO cows (63.8%) than pure HO cows (49.4%) to calve a third time, and a higher percentage of JE × HO cows calved a third time within 28, 34, and 40 mo of first calving than pure HO cows.

    2017-11-01

    Montbéliarde (MO) × Holstein (HO) and Viking Red (VR) × HO crossbred cows were compared with pure HO cows in 8 large, high-performance dairy herds in Minnesota. All cows calved for the first time from December 2010 to April 2014. Fertility and survival traits were calculated from records of insemination, pregnancy diagnosis, calving, and disposal that were recorded via management software. Body condition score and conformation were subjectively scored once during early lactation by trained evaluators. The analysis of survival to 60 d in milk included 536 MO × HO, 560 VR × HO, and 1,033 HO cows during first lactation. Cows analyzed for other fertility, survival, and conformation traits had up to 13% fewer cows available for analysis. The first service conception rate of the crossbred cows (both types combined) increased 7%, as did the conception rate across the first 5 inseminations, compared with the HO cows during first lactation. Furthermore, the combined crossbred cows (2.11 ± 0.05) had fewer times bred than HO cows (2.30 ± 0.05) and 10 fewer d open compared with their HO herdmates. Across the 8 herds, breed groups did not differ for survival to 60 d in milk; however, the superior fertility of the crossbred cows allowed an increased proportion of the combined crossbreds (71 ± 1.5%) to calve a second time within 14 mo compared with the HO cows (63 ± 1.5%). For survival to second calving, the combined crossbred cows had 4% superior survival compared with the HO cows. The MO × HO and VR × HO crossbred cows both had increased body condition score (+0.50 ± 0.02 and +0.25 ± 0.02, respectively) but shorter stature and less body depth than HO cows. The MO × HO cows had less set to the hock and a steeper foot angle than the HO cows, and the VR × HO cows had more set to the hock with a similar foot angle to the HO cows. The combined crossbred cows had less udder clearance from the hock than HO cows, more width between both front and rear teats, and longer

    The objective of this issue of Articulo – Journal of Urban Research is to examine the characteristics of border markets in a comparative perspective. In this introductory paper, I first discuss what makes African border markets different from other markets, and examine several factors that explain...... their unequal economic development: the presence of a trade community, the combination of trading and productive activities, and the relative porosity of borders. In a second part, I examine how border markets on the U.S.-Mexico border must simultaneously guarantee the security of the state while favoring...... regional trade. The last part of the paper argues that more policy attention should be paid to border markets which, despite being at the margin of states, are a vital component of their economy. Fifty years after most West African states became independent and just as NAFTA turns 20, it is high time...

    The impact of a deregulated energy market on customers in Ontario was discussed. In particular, the way in which Sunoco will deal with energy convergence and how Sunoco plans to generate interest among residential consumers in a deregulated and competitive energy market was described. Integrated energy solutions that offer customers value-added heating, ventilating and air conditioning products and services, inclusive of equipment sales, installation, repair, rental, leasing, financing, warranty, insurance and maintenance is the ultimate goal of Sunoco. The major retail issues in the energy market such as licensing of marketers, customer mobility, transfer of utility assets to affiliates, Ontario Hydro's market power in electrical generation, distribution of stranded debt charges, and a timetable for deregulation were also addressed. figs

    each local market. The Market Coupling algorithm provides as an output for each market: The set of accepted Block Orders; The Net Position for each Settlement Period of the following day; and The price (MCP) for each Settlement Period of the following day. The results of the Market Coupling algorithm are consistent with a number of 'High Level Properties'. The High Level Properties can be divided into two subsets: Market Coupling High Level Properties (constraints that the Market Results fulfill for each Settlement Period), and Exchanges High Level Properties (constraints that the Market Results must fulfill for each Settlement Period. They reflect the requirements of individual participants trading on the exchanges). Using the ATCs and NECs, the Market Coupling algorithm can determine for each Settlement Period the Price and Net Position of each market. A NEC is built for a given set of accepted Block Orders (Winning Subset). When a set of NECs is used to determine the prices and Net Positions of each market, the set of prices returned for each market may very well not be compatible with this assumed Winning Subset. The Winning Subset needs to be updated and the calculations run again with the derived new NEC. This procedure must be repeated until a stable solution is found. As a consequence, the Market Coupling algorithm involves iterations between two modules: The Coordination Module which is in charge of the centralized computations; The Block Selector of each exchange which performs the decentralized computations. The iterative nature of the algorithm derives from the treatment of Block Orders. The data flows and calculations of the iterative algorithm are described in the rest of the document

    Full Text Available The study was undertaken to evaluate the effect of urea supplemented and urea treated straw based diet on milk ureaconcentration. Six multiparous crossbred Karan-Fries (Holstein Friesian ✕ Tharparkar cows were blocked into threegroups of nearly equal body weight, DIM, milk yield and milk fat content and were randomized into a 3 ✕ 3 Latin squaredesign with 3-week period. Three experimental diets were fed to the animals. Composition of these diets were: Diet 1green maize, wheat straw and concentrate mixture; Diet 2 green maize, wheat straw, concentrate mixture (urea supplementedand molasses; Diet 3 green maize (4 % of total DM, 4 % urea treated wheat straw and concentrate mixture.Intake of DM and CP did not vary across the diets. Intake of digestible crude protein (DCP was found significantlyhigher in diet 2, while ME and NEL intakes were found significantly lower in diet 3 but did not differ between diets 1and 2. Average milk and plasma urea concentrations (mg dl-1 were found 29.2 ± 2.6, 45.3 ± 0.9, 34.5 ± 2.3 and 28.9± 2.4, 36.6 ± 1.4, 33.9 ± 2.2, respectively in diet 1, diet 2 and diet 3. Urea concentrations in morning milk sampleswere found significantly lower than noon or evening samples in all the three diets. Concentrations of urea in milk andplasma were found closely correlated (r = 0.94 and the regression equation developed was, plasma urea = 8.90 (.89+ .79 (.02 milk urea. Intake (g of DCP than CP, per unit (MCal of ME was found more closely associated with milk ureaconcentration. The study revealed that urea supplementation and urea treated straw based diet increased urea concentrationsignificantly in milk and plasma. Morning milk urea values that estimated at a time gap of 15 hr since last majorfeeding may be considered as the lowest level and can be used for interpretation to monitor feeding adequacy or reproductiveperformances in dairy cows.

    2002-01-01

    Nova Scotia's Energy Strategy is aimed at opening the electricity market to wholesale competition, allowing eligible wholesale customers (such as municipal distribution utilities) to buy their electricity from competitive sources. The Nova Scotia Electricity Marketplace Governance Committee (EMGC) is concerned that this will not promote long-term competition because these eligible customers form only a very small fraction (1.6 per cent) of the total electricity demand in the province. This report examines the possible extensions of competition beyond the minimum specified in the Energy Strategy. It also identifies approaches that the EMGC may consider, including other potential levels of competition and their associated issues. The report discussed the issue of implementing wholesale competition as it relates to unbundling of the transmission tariff from the cost of energy supply and from the cost of distribution in retail marketing. The stages of expanding the market scope were also described with reference to large industrial customers, medium industrial and large commercial customers, and small commercial and residential customers. The report states that it is unlikely that the transition to an open access transmission market will need to be reversed, as it is likely to be an essential component of any further development. The EMGC feels it could minimize future transition costs and promote future evolution of competition by recommending for an institutional and market structure that is compatible with a broader competitive market

    Heins, B J; Hansen, L B; De Vries, A

    2012-02-01

    Pure Holstein (HO) cows (n=416) were compared with Normande (NO) × HO (n=251), Montbéliarde (MO) × HO (n=503), and Scandinavian Red (SR) × HO (n=321) crossbred cows for survival, lifetime production, and profitability in 6 commercial herds in California. The SR crossbred cows were sired by both Swedish Red and Norwegian Red bulls. Cows calved from June 2002 to January 2009. For analysis of survival to subsequent calvings, lifetime production, and profitability, data were restricted to 3 of 6 herds because they had at least 20 cows in each of the breed groups. All cows had the opportunity to calve at least 4 times. Best prediction, which is used by USDA for national genetic evaluations in the United States, was used to determine lifetime production to 4 yr (1,461 d) in the herd after first calving from test-day observations. Production and survival were estimated after 4 yr to calculate lifetime profit. A profit function was defined to include revenues and expenses for milk, fat, protein, and other solids production; somatic cell count; reproduction; feed intake; calf value; salvage value; dead cow disposal; and fixed cost. The NO × HO (1.2%), MO × HO (2.0%), and SR × HO cows (1.6%) had significantly fewer deaths than did pure HO cows (5.3%) during the first 305 d of first lactation. All crossbred groups had significantly more cows that calved a second, third, and fourth time, and had mean survival that was 300 to 400 d longer than did pure HO cows. The NO × HO, MO × HO, and SR × HO cows had significantly higher lifetime fat plus protein production than did pure HO cows up to 1,461 d after first calving. For profitability (ignoring possible differences in health costs), NO × HO cows had 26% greater projected lifetime profit per cow, but 6.7% less profit per cow-day, than did pure HO cows. On the other hand, MO × HO and SR × HO cows had 50 to 44%, respectively, more projected lifetime profit per cow and 5.3 to 3.6%, respectively, more projected profit

    Full Text Available Objective The objective of this study was to compare the DNA methylation profile in the longissimus dorsi muscle between Small Tailed Han and Dorper×Small Tailed Han crossbred sheep which were known to exhibit significant difference in meat-production. Methods Six samples (three in each group were subjected to the methylated DNA immunoprecipitation sequencing (MeDIP-seq and subsequent bioinformatics analyses to detect differentially methylated regions (DMRs between the two groups. Results 23.08 Gb clean data from six samples were generated and 808 DMRs were identified in gene body or their neighboring up/downstream regions. Compared with Small Tailed Han sheep, we observed a tendency toward a global loss of DNA methylation in these DMRs in the crossbred group. Gene ontology enrichment analysis found several gene sets which were hypo-methylated in gene-body region, including nucleoside binding, motor activity, phospholipid binding and cell junction. Numerous genes were found to be differentially methylated between the two groups with several genes significantly differentially methylated, including transforming growth factor beta 3 (TGFB3, acyl-CoA synthetase long chain family member 1 (ACSL1, ryanodine receptor 1 (RYR1, acyl-CoA oxidase 2 (ACOX2, peroxisome proliferator activated receptor-gamma2 (PPARG2, netrin 1 (NTN1, ras and rab interactor 2 (RIN2, microtubule associated protein RP/EB family member 1 (MAPRE1, ADAM metallopeptidase with thrombospondin type 1 motif 2 (ADAMTS2, myomesin 1 (MYOM1, zinc finger, DHHC type containing 13 (ZDHHC13, and SH3 and PX domains 2B (SH3PXD2B. The real-time quantitative polymerase chain reaction validation showed that the 12 genes are differentially expressed between the two groups. Conclusion In the current study, a tendency to a global loss of DNA methylation in these DMRs in the crossbred group was found.

    Full Text Available Present study analyzed the changes in peripheral blood testosterone concentrations and testicular cytogram in relation to age and semen quality in crossbred males. Three different age groups of crossbred males viz. bull calves (6 months, n = 5, young bulls (15 months, n = 5 and adult bulls (4 to 6 years, n = 8 were utilized for the study. Testicular fine needle aspiration cytology technique was used to quantify testicular cytology and their indices. Peripheral blood testosterone concentrations were measured using enzyme-linked immunosorbent assay method. Semen samples collected from adult bulls were microscopically evaluated for quality parameters. Mean peripheral blood testosterone concentrations in bull calves, young bulls and adult bulls were 2.28±0.09 ng/mL, 1.42±0.22 ng/mL and 5.66±1.08 ng/mL respectively, and that in adult bulls were significantly different (p<0.01 from young bulls and bull calves. There was no significant difference between the proportion of different testicular cells in bull calves and young bulls. Between young and adult bulls, significant differences (p<0.01 were observed in the proportion of spermatocytes, spermatozoa, and sperm: Sertoli cell ratio. The proportions of Sertoli cells showed a significant difference (p<0.01 between the three age groups. The number of primary spermatocytes had a positive correlation with peripheral blood testosterone concentrations in bull calves (r = 0.719, p<0.01. Number of Sertoli cells per 100 germ cells was negatively correlated with blood testosterone concentration in young bulls (r = −0.713, p<0.01. Among different semen parameters in adult bulls, ejaculate volume (r = 0.790, p<0.05 had positive relationship, and sperm motility had significant negative correlation (r = −0.711, p<0.05 with testosterone concentrations. The number of Sertoli cells and Sertoli cell index had a positive correlation with various semen quality parameters (p<0.001. Results of the present study

We argue that Shiller’s work displays a tension between mimetic and anti-mimetic tendencies......, i.e. between understanding financial markets as captured by fads and fashions (mimesis), and at the same time understanding such markets on the basis of a notion of homo economicus (an essentially anti-mimetic figure). Identifying that tension not only sheds novel light on Shiller’s work, but also...... allows us to critically discuss Mirowski’s negative appraisal of Shiller’s behavioural finance programme. Further, we argue that the mimetic/anti-mimetic tension in Shiller’s work can equally be identified in a broader range of theories about financial markets, and that attending to it therefore opens up...

    A percolation model is presented, with computer simulations for illustrations, to show how the sales of a new product may penetrate the consumer market. We review the traditional approach in the marketing literature, which is based on differential or difference equations similar to the logistic equation (Bass, Manage. Sci. 15 (1969) 215). This mean-field approach is contrasted with the discrete percolation on a lattice, with simulations of "social percolation" (Solomon et al., Physica A 277 (2000) 239) in two to five dimensions giving power laws instead of exponential growth, and strong fluctuations right at the percolation threshold.

    Full Text Available A survey to demonstrate the presence or absence of genital campylobacteriosis and trichomonosis in cross-bred breeding bulls kept under smallholding dairy farms in the Tanga region of Tanzania was carried out during the period of January-June 1996. Sheath washings, swabs and preputial scrapings were collected from 58 randomly selected bulls. Campylobacter fetus subsp. venerealis was demonstrated in 3/58 (5.1 % and Tritrichomonas foetus in 0/58 (0 % of all bulls tested. Bull-level variables of level of taurine genes (62.5 % taurine genes, F2; 75 % taurine genes, F3 and age were not significantly associated with campylobacteriosis (P > 0.05. The result of the study identifies Campylobacter fetus subsp. venerelias as the agent of enzootic infertility in smallholder herds and suggests that may be a significant problem.

    Restricted participation in sequential markets may cause high price volatility and welfare losses. In this paper we therefore analyze the drivers of restricted participation in the German intraday auction which is a short-term electricity market with quarter-hourly products. Applying a fundamental electricity market model with 15-minute temporal resolution, we identify the lack of sub-hourly market coupling being the most relevant driver of restricted participation. We derive a proxy for price volatility and find that full market coupling may trigger quarter-hourly price volatility to decrease by a factor close to four.

  14. Transaction Pattern Based on Secondary Clientelism, Business Ideology and Market Development: The case of lime market in Hui Town

    2011-01-01

    Secondary clientelism is a special exchange relationship derived from primary clientelism. The market with transactions dependent on the secondary clientelism would be”because of”erembeddedness”. Using the lime market in Hui Town as a case, this paper tries to explore why this kind of markets could achieve market order from the perspective of the interconnection of market structure and market culture. Analysis demonstrates that, the coupling induction of structural embeddedness and cultural embeddedness is the deeper mechanism for the market development. Although the new business ideology and transactional dependence on networks originate from market structural transitions, active construction and choice behaviors of the manufacturers still manifest great importance.

    2012-01-01

    Full Text Available The purpose of this study was to compare the bone strength traits in two groups of pigs different in terms of genetic value, fast growth capability and meat deposition in the body. The study covered 33 fatteners of the Złotnicka Spotted breed (ZŁP and 20 crossbreds F1 (Polish Large White x Polish Landrace. Tibial bones were obtained following slaughter and evaluated in terms of properties and geometry, as well as bending and compressive strength. Mineral composition of the bone tissue was also established, i.e.: ash, Ca, P, Na, K, Zn and Mg. The significance of differences between the traits demonstrated by pigs in both groups subject to the study was estimated, with calculated overall correlations between the primary bone properties. The results confirmed significant differences in terms of geometry of the bones in both animal groups. In the ZŁP breed pigs, compared to the F1 crossbred group (PLW x PL, the outside and inside diameters of the tibial shaft were smaller (P ≤ 0.01, yet the average thickness of the wall of the bone was slightly larger. The bending force required to fracture the bone turned out to be lower in Złotnicka Spotted pigs, the opposite of the results obtained with regard to the compressive strength. Furthermore, calcium content, calcium-phosphorus ratio (Ca : P and sodium content were highly statistically or significantly larger in the bone tissue of the Złotnicka Spotted pigs. Consequently, the final results show that the bone strength demonstrated by modern pig breeds subject to intensive selection focused on high growth rate and increased meat deposition is in no way lower than the same trait recognized in the Złotnicka Spotted breed kept in preservative breeding conditions.

    2008-09-01

    The aim of this study was to determine how evaporative cooling modifies body function with respect to water metabolism and other variables relevant to milk synthesis in crossbred cattle. The study was conducted on two groups of 0.875HF:0.125RS crossbred Holstein cattle (87.5%) housed in an open-sided barn with a tiled roof (non-cooled animals) and in a close-sided barn under an evaporative cooling system (cooled animals). The maximum ambient temperature and relative humidity for the non-cooled group were 33°C and 61%, with the corresponding values for the evaporatively cooled barn being 28°C and 84%, respectively. The temperature humidity index (THI) of under non-cooled conditions was higher ( P glucose and triglyceride of cooled animals were not significantly different compared with values for non-cooled animals. No differences were seen in plasma hormonal levels for triiodotyronine (T3) and insulin-like growth factor-1 (IGF-1), but plasma cortisol and thyroxine (T4) levels tended to be lower in non-cooled animals. This study suggests that low cooling temperature accompanied by high humidity influences a galactopoietic effect, in part through increases in ECF, blood volume and plasma volume in association with an increase in DMI, which partitions the distribution of nutrients to the mammary gland for milk synthesis. Cooled animals were unable to maintain high milk yield as lactation advances even though a high level of body fluids was maintained during long-term cooled exposure. The decline in milk yield, coinciding with a decrease in net energy for lactation as lactation advances, could be attributed to a local change within the mammary gland.

    The objective of the present study to assess the effects of mesquite pod addition replacing corn (0, 250, 500, 750, and 1000 g/kg in the dry matter basis) on nutrient intake, animal performance, feeding behavior, nutrient digestibility, nitrogen balance, and microbial protein synthesis. Twenty-five Holstein-Zebu crossbred dairy steers at 219 ± 22 kg initial body weight and 18 months of age were used. The experiment lasted 84 days, divided into three periods of 28 days. A completely randomized design was used, and data were submitted to analysis using PROC GLM for analysis of variance and PROC REG for regression analysis using the software Statistical Analysis Systems version 9.1. Experimental diets were composed of Tifton 85 hay, soybean meal, ground corn, mesquite pod meal, and mineral salt. Samples of food offered were collected during the last 3 days of each period, and the leftovers were collected daily, with samples bulked per week. At the end of each 28-day period, the remaining animals were weighed to determine total weight gain and average daily gain. The assessment of behavioral patterns was performed through instantaneous scans in 5-min intervals for three consecutive 12-h days. A single urine sample from each animal was collected on the last day of each collection period at about 4 h after the first feeding. The replacement of corn by mesquite pod meal did not significantly influence treatments regarding nutrients intake, animal performance, and feeding behavior. Retained and consumed nitrogen ratio did not statistically differ between replacement levels. Likewise, there were no statistical differences regarding microbial protein synthesis and efficiency between replacement levels. Mesquite pod meal can be used in Holstein-Zebu crossbred dairy steers' diet with total corn replacement.

    2001-01-01

    A model for the competitive electricity market in New Brunswick was not specified by the White Paper: New Brunswick Energy Policy, published in March 2001. One of the tasks of the Market Design Committee (MDC) is to select a market model for the province. This report was prepared with this objective in mind. It begins by providing a description of the basic functions that must be performed by any electricity system. Different market models will function differently, and a descriptions of how the functions would be performed under each model is presented. Considering the specific size and geographic location of New Brunswick, a number of actual markets that could be of interest are presented. The various electricity markets normally use one of four market models: vertically integrated monopoly utility, a competitive pool market, a bilateral contract market, and a single-buyer market. The first model was not explained as it represents the existing, non-competitive model whereby the government owns and/or regulates price and investment decision. The case where a market operator receives bids and offers from buyers and sellers and matches them to derive a price and schedule for the spot market is what is called the competitive pool market. When electricity trade takes place through a series of contracts between individual buyers and sellers, it is referred to as a bilateral contract market. Finally, the single-buyer market is defined as a monopoly where the buyer purchases from multiple sellers based on competition amongst them. Different examples are provided of applications of the three markets described in the paper. Both New England and New Zealand were chosen to better illustrate the concepts of a fully competitive pool-based market, as they either have close ties to New Brunswick, or share physical similarities. The single-buyer model is illustrated by the case of Northern Ireland where size is similar. The choices made in Quebec were described in the final

    Full Text Available In the late 1990s, a new financial market was developed - a market for weather derivatives, so that the risk managers could hedge their exposure to weather risk. After a rather slow start, the weather derivatives market had started to grow rapidly. Risk managers could no longer blame poor financial results on the weather. Weather risk could now be removed by hedging procedure. This paper will explain briefly what the weather derivatives are and will point out at some of the motives for use of derivatives. Thereafter we will look at the history of the weather risk market, how the weather derivatives market has developed in recent years and also who are the current and potential players in the weather derivatives market.

  5. Market Power in Laboratory Emission Permit Markets

    International Nuclear Information System (INIS)

    Godby, R.

    2002-01-01

    Many proposals suggesting the use of markets to control pollution assume markets will be competitive. When markets do not exhibit competitive characteristics, however, should they still be expected to result in efficiency improvement relative to traditional approaches? This paper employs experimental economic methods to examine the effect of market structure on the use of marketable emissions permits. Results indicate that in a market with one dominant firm and a number of fringe firms, strategic manipulation occurs repeatedly in the laboratory as predicted by market power models, undermining the allocative and dynamic efficiency benefits such markets offer. When firms compete in a downstream product market dominated by the same single firm, market efficiency can actually be reduced with the implementation of permit markets. Final market efficiencies reflect initial endowments and are influenced by competitive conditions elsewhere in the economy, indicating that policy-makers should carefully consider whether markets are appropriate in such circumstances

This aspect will basically alter our way to teach and to learn. In its dimensions, arguably changes will be like anything we has seen before. We try to assess how will be all unfold but, anyway, academic field response at this challenge should be integrated and comprehensive, involving all stakeholders both public and private sectors, because these changes herald upheaval of whole organizations. The educational service is a special one, delivered today but with effects in the future, the future of the individual, the future of generation, the future of nations. The educational service policy adapted to the requirements of time, brings to the front the opportunity of academic marketing. To analyze demand in a professional way, to measure trends and correlated university programs with the forecast demand for jobs, it is the subject. In the case of academic education, we are talking also about cost, distribution and promotion policies, but being a special service we also discuss about ethic boundaries. This work is an open chapter focusing studies on academic megamarketing, the work keeping up with the pace of change, students enrolment mobility, overtakes job market, and an imposed win-win-win formula, applied for students, local community and academic field.

Possibilities for implementation of regionally integrated marketing communications strategy in the Western Balkans are analyzed based on the assessment of macro-marketing environmental factors and consumers attitudes. Study results have shown satisfactory conditions for the implementation of regionally integrated marketing communications in four countries of the region. Consequently, in the period of the most recent economic crisis companies operating on this market which decide to implement regionally integrated marketing communications strategy may make significant cost-savings through centralization of their marketing communications activities, organizational learning and synergy rather then from cutting their media budgets.

  10. Does the market maker stabilize the market?

    Science.gov (United States)

    Zhu, Mei; Chiarella, Carl; He, Xue-Zhong; Wang, Duo

    2009-08-01

    The market maker plays an important role in price formation, but his/her behavior and stabilizing impact on the market are relatively unclear, in particular in speculative markets. This paper develops a financial market model that examines the impact on market stability of the market maker, who acts as both a liquidity provider and an active investor in a market consisting of two types of boundedly rational speculative investors-the fundamentalists and trend followers. We show that the market maker does not necessarily stabilize the market when he/she actively manages the inventory to maximize profits, and that rather the market maker’s impact depends on the behavior of the speculators. Numerical simulations show that the model is able to generate outcomes for asset returns and market inventories that are consistent with empirical findings.

    We investigate the relative market efficiency in financial market data, using the approximate entropy(ApEn) method for a quantification of randomness in time series. We used the global foreign exchange market indices for 17 countries during two periods from 1984 to 1998 and from 1999 to 2004 in order to study the efficiency of various foreign exchange markets around the market crisis. We found that on average, the ApEn values for European and North American foreign exchange markets are larger than those for African and Asian ones except Japan. We also found that the ApEn for Asian markets increased significantly after the Asian currency crisis. Our results suggest that the markets with a larger liquidity such as European and North American foreign exchange markets have a higher market efficiency than those with a smaller liquidity such as the African and Asian markets except Japan.

    Some basic facts regarding derivatives in the electric power industry were discussed based on experiences in the natural gas industry. Derivatives were described as financial instruments that have no value of their own but derive their value from other assets, such as commodities. Futures and Options are the two forms of derivatives. Electricity as a commodity was characterized, and a historical parallel was drawn between deregulation in the natural gas and electric power industry. Short term and long term factors impacting the market and market dynamics impacting derivatives were identified. The latter include: (1) volatility, (2) liquidity, (3) correlations, and (4) price discovery. In contrast to the natural gas market, the electricity market is considered as lacking liquidity and in need of moving farther along the maturity timeline. The question of natural gas/ electricity convergence was also addressed refs., tabs., figs

    Edin, Karl-Axel

    2006-12-01

    Despite having had a deregulated electricity market in Sweden for over ten years we still need to increase our understanding as to how deregulated electricity markets actually work and how possible problems are to be solved. One question that is always in focus is if the competition between generators in the Nordic electricity market really works the way it was intended. Many argue that the concentration in ownership of generation plants already has gone too far. Together with joint ownership in nuclear facilities and barriers for entrance, critics say that this has resulted in higher electricity prices than necessary. In this report different methods to (ex ante) study potential possibilities for generating firms to influence the electricity price (market power) and (ex post) discover possible manipulation through analysing the spot price and other observed factors on the electricity market are analysed. The purpose of the longer underlying paper is to give a comprehensive treatment of the electricity market with storage, i.e. hydro power, with an auction market organisation and to test the models on the Nordic market in order to explore the explanatory power of auction market theory and the theory of contestable market. The main theoretical effort in the paper concerns auction theory with inventories. The paper develops an inter-temporal auction model of a thermal-hydro power market. Parallel to the derivation of the basic equations a numerical model is developed in order to illustrate the results of the model. Section 2 of the present paper summarizes the basic equations (derived in the longer paper) for an inter-temporal auction thermal-hydro market. Section 3 contains the illustrations of solutions to equations for some stylized markets. In section 4 the auction model is tested on the Nordic market

    Markets influence the global patterns of urbanization, deforestation, agriculture and other land use systems. Yet market influence is rarely incorporated into spatially explicit global studies of environmental change, largely because consistent global data are lacking below the national level. Here we present the first high spatial resolution gridded data depicting market influence globally. The data jointly represent variations in both market strength and accessibility based on three market influence indices derived from an index of accessibility to market locations and national level gross domestic product (purchasing power parity). These indices show strong correspondence with human population density while also revealing several distinct and useful relationships with other global environmental patterns. As market influence grows, the need for high resolution global data on market influence and its dynamics will become increasingly important to understanding and forecasting global environmental change.

  9. Derivative chameleons

    2012-01-01

    We consider generalized chameleon models where the conformal coupling between matter and gravitational geometries is not only a function of the chameleon field φ, but also of its derivatives via higher order co-ordinate invariants (such as ∂ μ φ∂ μ φ,□φ,...). Specifically we consider the first such non-trivial conformal factor A(φ,∂ μ φ∂ μ φ). The associated phenomenology is investigated and we show that such theories have a new generic mass-altering mechanism, potentially assisting the generation of a sufficiently large chameleon mass in dense environments. The most general effective potential is derived for such derivative chameleon setups and explicit examples are given. Interestingly this points us to the existence of a purely derivative chameleon protected by a shift symmetry for φ → φ+c. We also discuss potential ghost-like instabilities associated with mass-lifting mechanisms and find another, mass-lowering and instability-free, branch of solutions. This suggests that, barring fine-tuning, stable derivative models are in fact typically anti-chameleons that suppress the field's mass in dense environments. Furthermore we investigate modifications to the thin-shell regime and prove a no-go theorem for chameleon effects in non-conformal geometries of the disformal type

The most general effective potential is derived for such derivative chameleon setups and explicit examples are given. Interestingly this points us to the existence of a purely derivative chameleon protected by a shift symmetry for φ → φ+c. We also discuss potential ghost-like instabilities associated with mass-lifting mechanisms and find another, mass-lowering and instability-free, branch of solutions. This suggests that, barring fine-tuning, stable derivative models are in fact typically anti-chameleons that suppress the field's mass in dense environments. Furthermore we investigate modifications to the thin-shell regime and prove a no-go theorem for chameleon effects in non-conformal geometries of the disformal type.

    Full Text Available Aim: Present study aimed to evaluate the different episodes of clinical mastitis (CM and influence of duration of treatment and seasonality on the occurrence of different episodes of CM in crossbred cows. Materials and Methods: A total of 1194 lactation data of crossbred CM cows were collected from mastitis treatment record from 2002 to 2012. Data of CM cows were classified into types of episodes (pattern of repeated or multiple episodes occurrence and number of episodes (magnitude of multiple cases. Types of episodes were divided as single (clinical cure by a single episode of treatment, relapse (retreatment of the same cow within 21 days, recurrence (new CM at least 21 days after treatment, and both (relapse and recurrence. The season was classified as winter (December to March, summer (April to June, rainy (July to September, and autumn (October to November. The difference between incidences of different types of CM episodes and the association between number or type of CM episodes with duration of treatment and seasons of CM occurrence were analyzed by Chi-square test. Results: Among 1194 animals suffered with CM, 53, 16, and 18% had the single episode, relapse, and recurrence, respectively; while 13% suffered by both relapse and recurrence. We estimated the duration of treatment and found 80% of the cows treated 1-8 days, in which 65% treated for 1-4 days, while 35% cows were treated for 5-8 days. Further, 12% cows treated for 9-15 days and 7.5% cows treated >15 days. The relationship between duration of treatment and different episodes of CM revealed that 1-8 days treated cows were mostly cured by the single episode with less relapse and recurrence. In contrast, the incidences of recurrence and relapse episodes were higher in cows treated for more than 9 days. The highest incidence of relapse was noticed in winter (36% than other seasons (10-28%, while the recurrence was less during autumn (9% compared to other seasons (20-40%. Conclusion

    The international electric utility industry is undergoing a radical transformation from an essentially regulated and monopolistic industry to an industry made uncertain with impending deregulation and the advent of competitive forces. This paper investigates the development of an options market for bulk power trading in a market setup while considering power system planning and operational constraints and/or requirements. In so doing it considers the different market based financial derivative instruments while can be used to trade electrical power in bulk and examines how established tools such as Optimal Power Flow (OPF) may be applied in helping to develop a price for bulk power transactions under a market based setup.

    This experiment aimed to evaluate the effect of calcium soap of fatty acid (CSFA) supplementation on serum biochemical and hormones and ovarian activity during out-of-the-breeding season in ewes. Twelve crossbred ewes, 2-3 years of age and weighting 45–55 kg, were allocated into two equal groups. The first group was control and the other was treated with 50 g/head of CSFA. All ewes were fed basal diet and treated with 60 mg of medroxy progesterone acetate intravaginal sponge for 12 day. At the third day of sponge removal, the CSFA-treated group was given 50 g/head of CSFA daily for two estrous cycles. During the estrus phase, ovarian activity was detected using ultrasonography in both groups. All ewes were then subjected to natural breeding and conception rate. Blood samples were collected from all ewes during treatment period. Results revealed significant (P < 0.05) increases in serum cholesterol, triglycerides, low-density lipoprotein cholesterol, glucose, and progesterone levels with decrease in calcium and phosphorous levels in treated group. In treated group, normal-size ovaries and more than one follicle on the ovaries were detected and pregnancy rate increased. In conclusion, CSFA supplementation was effective to maintain the reproductive performance when ewes were out of the breeding season. PMID:22629155

    Two experiments are described where a progeny of Bos taurus x Bos indicus crossbred cows were reared by partial suckling or bucket rearing (Experiment I), and partially suckled calves were weaned at 12 or 24 weeks of age (Experiment II). The results of Experiment I suggest that calf rearing method had no significant effect in the yield of milk extracted from the cows by hand milking although there were effects on the shape of the lactation curve. Cows showed similar patterns of live weight and body condition losses and gains and there were no significant effects on the length of the post partum interval. Suckled calves were lighter at weaning (P <0.01) but there were no differences in live weight between treatments at 52 weeks of age. The main advantage of partial suckling was that the calves took advantage of residual milk which was estimated as 28-29% of the total yield. The results from Experiment II suggest that there were no advantages in terms of milk yield or calf growth by extending the suckling period to 24 weeks. The post partum intervals observed in Experiment II were substantially longer than those in Experiment I, possibly because of greater live weight/body condition losses experienced by cows in the second experiment.

    Full Text Available Bovine viral diarrhea virus (BVDV has major impacts on beef cattle production worldwide, but the understanding of host animal genetic influence on illness is limited. This study evaluated rectal temperature, weight change and feed intake in Bos indicus crossbred steers (n = 366 that were challenged with BVDV Type 1b, and where family lines were stratified across three vaccine treatments of modified live (MLV, killed, (KV or no vaccine (NON. Pyrexia classification based on 40.0 °C threshold following challenge and vaccine treatment were investigated for potential interactions with sire for weight change and feed intake following challenge. Pyrexia classification affected daily feed intake (ADFI, p = 0.05, and interacted with day (p < 0.001 for ADFI. Although low incidence of clinical signs was observed, there were marked reductions in average daily gain (ADG and cumulative feed intake during the first 14 day post-challenge; ADG (CV of 104% and feed efficiency were highly variable in the 14-day period immediately post-challenge as compared to the subsequent 14-day periods. A sire × vaccine strategy interaction affected ADFI (p < 0.001, and a sire by time period interaction affected ADG (p = 0.03 and total feed intake (p = 0.03. This study demonstrates that different coping responses may exist across genetic lines to the same pathogen, and that subclinical BVDV infection has a measurable impact on cattle production measures.

    Full Text Available Aim: The present study was undertaken to identify whether single nucleotide polymorphism (SNP rs109231409 located on mannose-binding lectins 1 (MBL1 gene was associated with mastitis tolerance/susceptibility. Materials and Methods: After grouping 100 Vrindavani crossbred cattle as mastitis positive and negative animals, they were genotyped using polymerase chain reaction (PCR-restriction fragment length polymorphisms method. Gene and genotype frequencies of different patterns were estimated by standard procedure (POPGENE version 1.32, (University of Alberta, Canada and statistical analysis was carried out by logistic regression methods using STATA 12 software (StataCorp LP, USA. Results: The 588 bp fragment of MBL1 gene was amplified using PCR. PCR product was digested with ApaI restriction enzyme showed two distinct genotypes viz., GG (311 bp and 272 bp fragments and GA (588 bp, 311 bp and 277 bp fragments. The gene, genotype frequencies, average heterozygosity, polymorphic information content and χ2 values for the locus rs109231409 was ascertained. Conclusions: No significant association between SNP “rs109231409” with mastitis tolerance was found. Although there is a lack of association, further studies have to be undertaken in a large population in order to validate the impact of rs109231409 (g.855G >A on mastitis tolerance.

    Thirty-six crossbred calves (Holstein cross) of 5 days of age were used to study the effect of garlic extract feeding on their performance up to the age of 2 months (pre-ruminant stage). They were randomly allotted into treatment and control groups (18 numbers in each group). Performance was evaluated by measuring average body weight (BW) gain, feed intake (dry matter (DM), total digestible nutrient (TDN) and crude protein (CP)), feed conversion efficiency (FCE; DM, TDN and CP), faecal score, faecal coliform count and feeding cost. Diets were the same for the both groups. In addition, treatment group received garlic extract supplementation at 250 mg/kg BW per day per calf. Body weight measured weekly, feed intake measured twice daily, proximate analysis of feeds and fodders analysed weekly, faecal scores monitored daily and faecal coliform count done weekly. There was significant increase in average body weight gain, feed intake and FCE and significant decrease in severity of scours as measured by faecal score and faecal coliform count in the treatment group compared to the control group (P Feed cost per kilogramme BW gain was significantly lower in the treatment group compared to control group (P calves for better performance.

    Sixteen male rumen fistulated calves (18-24 months of age; 180-200 kg body wt) were divided into four groups of four animals each. Animals in all groups were fed wheat straw ad lib as the sole roughage. However, animals in Gr I were fed concentrate mixture at maintenance level whereas, animals in Gr II, III and IV had free access to urea molasses mineral block (UMMB) lick existing modified 'A' and modified 'B', respectively without any concentrate mixture. Dry matter intake (kg/100 kg body wt) were similar in four groups. However, straw intake was significantly higher in UMMB supplemented groups. Protozoa production rate (gN/d) was significantly higher in Gr I (7.112 + 0.27) as compared to Gr II (4.302 + 0.51), Gr III (4.743 + 0.27) and Gr IV (4.501 + 0.25). Thus, these results indicated that protozoal production rate in the rumen is significantly lower when crossbred calves were fed on wheat straw based diet supplemented with different UMMB licks as compared to those fed concentrate mixture at maintenance level.

    Bardoscia, Marco; Livan, Giacomo; Marsili, Matteo

    2012-01-01

    We study the emergence of instabilities in a stylized model of a financial market, when different market actors calculate prices according to different (local) market measures. We derive typical properties for ensembles of large random markets using techniques borrowed from statistical mechanics of disordered systems. We show that, depending on the number of financial instruments available and on the heterogeneity of local measures, the market moves from an arbitrage-free phase to an unstable one, where the complexity of the market—as measured by the diversity of financial instruments—increases, and arbitrage opportunities arise. A sharp transition separates the two phases. Focusing on two different classes of local measures inspired by real market strategies, we are able to analytically compute the critical lines, corroborating our findings with numerical simulations.

    The purpose of chapter 3 is to provide a conceptual framework for understanding marketing. Although it is often considered to be, marketing is not really a new activity for nursing organizations. What is perhaps new to most nursing organizations is the conduct of marketing activities as a series of interrelated events that are part of a strategic marketing process. The increasingly volatile nursing environment requires a comprehensive approach to marketing. This chapter presents definitions of marketing, the marketing mix, the characteristics of nonprofit marketing, the relationship of strategic planning and strategic marketing, portfolio analysis, and a detailed description of the strategic marketing process. While this chapter focuses on marketing concepts, essential components, and presentation of the strategic marketing process, chapter 4 presents specific methods and techniques for implementing the strategic marketing process.
