Download or read book Genetics of Growth and Reproductive Performance of Kenya Boran Cattle written by Chrilukovian Wasike and published by LAP Lambert Academic Publishing. This book was released on 2012 with total page 136 pages. Available in PDF, EPUB and Kindle. Book excerpt: Animal models were used to estimate genetic parameters and trends for growth and reproduction of Kenya Boran cattle. Sex, age of animal, parity and year-season effects affected birth weight (BW), weaning weight (WW), 12month weight (12W), 18month weight (18W) and 24month weight (24W). Herd-year-season of birth and calving, and age at birth and calving affected age at first calving (AFC), pooled calving interval (CI) and calving intervals (CI1), (CI2) and (CI3). Direct heritability (h2) from univariate analyses of growth were low to moderate. Maternal heritability for WW, 12W and 24W were low. Direct-maternal genetic correlations were negative. The h2 for reproductive traits were low. The h2 from multivariate analyses for growth were moderate. The genetic correlations (rg) between growth traits were positive. The rg between reproductive traits were negative. The h2 from random regression analysis ranged from 0.11 to 0.33. The rg were positive tending to unity but declined with increase in lag between age points similar to permanent environmental correlation. The rp was negative between extreme points and positive between intermediate and later points with spikes along the diagonal

Available in PDF, EPUB and Kindle. Book excerpt: Genetics and Breeding for Disease Resistance of Livestock is a solid resource that combines important information on the underlying genetic causes and governing factors for disease resistance in food animals and applications for breeding purposes. It describes genomics at each species level to help researchers and students understand disease resistance and immunology using genomics and its application in breeding for disease resistance. This useful reference makes it easy for readers to understand and undergo further research in immunology and disease resistance for livestock. It includes novel applications and research material that is ideal for students, teachers, academicians and researchers. - Presents basic principles and protocols to describe research methodologies through diagrammatic illustrations with figures, flow charts, examples, and references - Covers various disease occurrences in livestock and the methodologies available to identify the various pathogens responsible for these diseases - Includes advanced breeding techniques and practical applications
