Viral determinants of rotavirus pathogenicity in pigs: production of reassortants by asynchronous coinfection.

Tauscher, G I; Desselberger, U

A porcine rotavirus (prv), variant 4F, isolated in tissue culture from the feces of a Chinese pig with diarrhea, was found to have become highly pathogenic when passaged in gnotobiotic piglets (J. C. Bridger, B. Burke, G. M. Beards, and U. Desselberger, J. Gen. Virol. 73:3011-3015, 1992). Comparison...

The estrogen receptor locus is associated with a major gene influencing litter size in pigs.

Vincent, A; Vaske, D; Southwood, O; Mileham, A; Wang, L; Short, T; Tuggle, C; Rothschild, M; Jacobson, C; Sasaki, S; Plastow, G

Identification of individual major genes affecting quantitative traits in livestock species has been limited to date. By using a candidate gene approach and a divergent breed cross involving the Chinese Meishan pig, we have shown that a specific allele of the estrogen receptor (ER) locus is associat...

Statistical identification of major genes in pigs.

Janss, L.L.G.

Litter size is an important characteristic in pig breeding. Apart from selection within available lines, also the development of a synthetic line with the Chinese Meishan breed could be an interesting approach to obtain a line with an increased level of litter size. To investigate genetic aspects of...

Mitochondrial diversity in European and Chinese pigs is consistent with population expansions that occurred prior to domestication

Fang, Meiying; Andersson, Leif

Mitochondrial DNA (mtDNA) diversity in European and Asian pigs was assessed using 1536 samples representing 45 European and 21 Chinese breeds. Diagnostic nucleotide differences in the cytochrome b (Cytb) gene between the European and Asian mtDNA variants were determined by pyrosequencing as a rapid ...

Identification of (non-) Mendelian factors affecting pork production

Koning, D.J., de

This thesis describes the analysis of a large experiment in which Chinese Meishan pigs were crossed with pigs from Dutch commercial lines. Three generations of pigs from this experiment were characterized for molecular markers that cover the entire porcine genome. Linkage was studied between these m...

Genome-wide scan for body composition in pigs reveals important role of imprinting

van Arendonk, Johan A. M.; de Koning, Dirk-Jan; Harlizius, Barbara; Rattink, Annemieke P.; Brascamp, E. W.; Groenen, Martien A. M.

The role of imprinting in body composition was investigated in an experimental cross between Chinese Meishan pigs and commercial Dutch pigs. A whole-genome scan revealed significant evidence for five quantitative trait loci (QTL) affecting body composition, of which four were imprinted. Imprinting w...

Effects of active immunization against GnRH on serum LH, inhibin A, sexual development and growth rate in Chinese female pigs

Zeng, X.Y.; Turkstra, J.A.; Tsigos, A.; Meloen, R.H.; Liu, X.Y.; Chen, F.Q.; Schaaper, W.M.M.; Oonk, H.B.; Guo, D.Z.

Surgical castration of young female pigs is common practice in Chinese pig farming today. The purpose of the present study is to investigate anti-GnRH immunization as a practical alternative to surgical castration for female pigs. Thirty-six Chinese female crossbred pigs (Chinese YananxYorkshire) we...

Biodiversity of pig breeds from China and Europe estimated from pooled DNA sample differences in microsatellite variation between two areas of domestication

Megens, H.J.W.C.; Crooijmans, R.P.M.A.; SanChristobal, M.; Hui, X.; Li, N.; Groenen, M.A.M.

Microsatellite diversity in European and Chinese pigs was assessed using a pooled sampling method on 52 European and 46 Chinese pig populations. A Neighbor Joining analysis on genetic distances revealed that European breeds were grouped together and showed little evidence for geographic structure, a...

Active immunization against gonadotrophin-releasing hormone in Chinese male pigs: effects of dose on antibody titer, hormone levels and sexual development

Zeng, X.Y.; Turkstra, J.A.; Meloen, R.H.; Liu, X.Y.; Chen, F.Q.; Schaaper, W.M.M.; Oonk, H.B.; Guo, D.Z.; Wiel, D.F.M., van de

The objective of this study was to determine the optimal dose of a GnRH vaccine for immunocastration of Chinese male pigs, based on immune, endocrine and testicular responses. Forty-two crossbred (Chinese Yanan x Large White) male pigs were randomly assigned to one of the five treatments as follows:...

A whole genome scan for Quantitative Trait Loci (QTL) affecting teat number in pigs

Hirooka, H.; Koning, D.J., de; Harlizius, B.; Arendonk, J.A.M., van; Rattink, A.P.; Groenen, M.A.M.; Brascamp, E.W.

A whole-genome scan was conducted using 132 microsatellite markers to identify chromosomal regions that have an effect on teat number. For this purpose, an experimental cross between Chinese Meishan pigs and five commercial Dutch pig lines was used. Linkage analyses were performed using interval map...
