Taschenbuch. Zustand: Neu. Neuware -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 diagonalBooks on Demand GmbH, Überseering 33, 22297 Hamburg 136 pp. Englisch.

Taschenbuch. Zustand: Neu. Neuware -The main author of this publication is a Veterinary Doctor, Master and PhD in Animal Science graduated from the Federal University of Pelotas (Rio Grando do Sul, Brazil). He taught beef cattle and Rural Administration courses at the University of the Campanha Region (URCAMP), and since 2014 he has been an Adjunct Professor at the State University of Rio Grande do Sul (UERGS), teaching several courses in the area of Animal Production for the Agronomy, Rural Development and Agroindustrial Management courses and the Higher Technology Course in Agroindustry. He is coordinator of the research group GEPAFO (Study Group on Livestock and Agriculture of the Western Frontier). He carried out his doctoral experiment at the Bioinformatics and Genomic Statistics Laboratory (Embrapa CPPSul), conducting studies with an emphasis on the temperament-behaviour-genotype relationship of beef cattle. He is currently developing research projects on sheep farming, livestock production in natural fields and technical-economic analysis of animal production systems (ruminants). He is in the process of broadening his study base by attending his second degree in Economics at the Federal University of Pampa.Books on Demand GmbH, Überseering 33, 22297 Hamburg 56 pp. Englisch.

Buch. Zustand: Neu. Neuware - Since the time of domestication more than 10,000 years ago, cattle have played an increasingly crucial role in the development of human civilizations. Progress has been quite remarkable since the turn of the century; the sequencing of the bovine genome in 2009 launched new avenues for furthering our understanding of theoretical and practical aspects of cattle genetics.Covering a vast array of questions, this book reviews major topics from molecular and developmental genetics, disease resistance and immunogenetics to genetic improvement of dairy and beef breeds, addressing all current problems in the field. This second edition includes a new team of authors and completely new chapters on the genetics of fat production, nutrition, feed intake and efficiency, growth and body composition. Fully updated throughout, it provides a valuable resource on cattle genetics for researchers, breeders, veterinarians and postgraduate students.
