Available in PDF, EPUB and Kindle. Book excerpt: The prediction of producing desirable traits in offspring such as increased growth rate or superior meat, milk and wool production is a vital economic tool to the animal scientist. Summarizing the latest developments in genomics relating to animal breeding values and design of breeding programs, this new edition includes models of survival analysis, social interaction and sire and dam models, as well as advancements in the use of SNPs in the computation of genomic breeding values.

Download or read book Genetic Relationships for Milk and Fat Yields Between Brazilian and United States Holstein Cattle Populations written by Claudio Napolis Costa and published by . This book was released on 1998 with total page 394 pages. Available in PDF, EPUB and Kindle. Book excerpt: Genetic relationships between Brazilian and U.S.A. Holstein cattle populations were studies using firstlactation 305-d ME milk and fat records of 29,413 daughters of 705 sires in Brazil and 726,932 daughters of 701 sires in the U.S.A. There were 358 sires with daughter records in both countries. Data sets consisted of all herds and low and high herds stratified by within-year standar deviation for milk (HYSD) computed within counthin country. Components of (co) variance, heritability, and genetic correlations for milk and fat yields were estimated using three data groupings: all, low and high HYDS data sets form within-country and between-country bivariete and multivariate analyses, simutaneous milk and fat yields in both countries. A sire model was solved with a restricted Maximum Likelihood (REML) derivative-free algorithm. Heritabilies for milk and fat yields using all the data were smaller in Brazil (.26 and .23) than in the in the U.S.A. (.33 and .36). Genetic correlations between milk and fat were .79 in Brazil and .62 in the U.S.A. Sire and residual variances for milk yield in Brazil were 59% and 81% (all herds), 51% and 58% (low HYSD herds), and 59% and 101% (high HYSD herds) as large as those obtained for all the U.S.A. data. corresponding percentage values for fat yield were 39% and 65%, and 48%, and 41 and 80%, respectively. Genetic correlations obtained from biavariate analyses between countries ranged from .79 to .87 for milk yield and were .89 or .90 for fat yield. Parameter estimates using all data for bibariate and multivariate analyses were essentially the same. Correlated response from sire selection using the U.S.A. information increased with average HYSD Brazil: daughter response was greatest (.77 kg/kg for milk yield and .63 kg/kg for fat yield) based on information from U.S.A. half-sisters in low HYSD herds. Unequal daughter responses from unequal genetic (co) variances under restrictive Brazilian conditions support the presence of an interaction between genetype and environment, which affects the yield expectation of daughters of U.S.A. sires performing in Brazilian herd enrironments.
