Early growth performance of Bos taurus × Bos indicus cattle crosses in Ethiopia: estimation of individual crossbreeding effects
Journal of Animal Breeding and Genetics - Tập 120 Số 4 - Trang 245-257 - 2003
S. Demeke, F.W.C. Neser, S.J. Schoeman
SummaryIn an effort to estimate breed differences, heterotic and recombination effects, a total of 4957 birth weight (BWT), 4245 weaning weight (WWT) and 3330 yearling weight (YWT) records collected from 38 crossbred and three purebred genotypes generated from crossing Friesian (F), Jersey (J) and Simmental (S) with the Boran (Bo), Barca (Ba) and Horro (Ho) (... hiện toàn bộ
Early growth performance of Bos taurus x Bos indicus cattle crosses in Ethiopia: Evaluation of different crossbreeding models
Journal of Animal Breeding and Genetics - Tập 120 Số 1 - Trang 39-50 - 2003
S. Demeke, F.W.C. Neser, S.J. Schoeman
SummaryFive genetic models were evaluated for goodness‐of‐fit and estimation of crossbreeding parameters using 41 genotypes produced from crossing three Bos taurus (Friesian, Jersey and Simmental) with three Bos indicus (Boran, Barca and Horro) breeds. The traits used for testing of the models were birth weight,...... hiện toàn bộ
Multi‐breed genetic evaluation in a Gelbvieh population
Journal of Animal Breeding and Genetics - Tập 124 Số 5 - Trang 286-295 - 2007
Andrés Legarra, J. K. Bertrand, T. Strabel, R. L. Sapp, Juan Pablo Sánchez, I. Misztal
SummaryA multi‐breed model was presented for the genetic evaluation of growth traits in beef cattle. In addition to the fixed effects, random direct and maternal genetic effects, and random maternal permanent environmental effects are considered; the model also fits direct and maternal heterosis and direct and maternal breed‐of‐founder (BOF) × generation group effe...... hiện toàn bộ
Reliable computing in estimation of variance components
Journal of Animal Breeding and Genetics - Tập 125 Số 6 - Trang 363-370 - 2008
I. Misztal
SummaryThe purpose of this study is to present guidelines in selection of statistical and computing algorithms for variance components estimation when computing involves software packages. For this purpose two major methods are to be considered: residual maximal likelihood (REML) and Bayesian via Gibbs sampling. Expectation‐Maximization (EM) REML is regarded as a v...... hiện toàn bộ
Analysis of pedigree and conformation data to explain genetic variability of the horse breed Franches‐Montagnes
Journal of Animal Breeding and Genetics - Tập 123 Số 2 - Trang 114-121 - 2006
Pierre-André Poncet, W. Pfister, Jeannette Muntwyler, Marie-Louise Glowatzki-Mullis, Claude Gaillard
SummaryFranches‐Montagnes is the only native horse breed in Switzerland, therefore special efforts should be made for ensuring its survival. The objectives of this study were to characterize the structure of this population as well as genetic variability with pedigree data, conformation traits and molecular markers. Studies were focused to clarify if this populatio...... hiện toàn bộ
Opportunities for investment into small ruminant breeding programmes in Brazil
Journal of Animal Breeding and Genetics - Tập 136 Số 5 - Trang 313-318 - 2019
Raimundo Nonato Braga Lôbo
AbstractThe social contribution of goat and sheep industries is very important to many Brazilian families mainly in semi‐arid regions of the country. However, the productive chains of these two species in Brazil are unorganized and ultimately informal. On the other hand, there is potential for growth and development to which an upscaling of breeding programmes will...... hiện toàn bộ
Genetic background of claw disorders in the course of lactation and their relationships with type traits
Journal of Animal Breeding and Genetics - Tập 130 Số 6 - Trang 435-444 - 2013
E. Gernand, D.A. Döhne, Sven König
SummaryRandom regression threshold animal models were applied to binary longitudinal claw disorder data for studying genetic parameters of all claw disorders (ACD), as well as to claw disorders divided into different categories: non‐purulent claw disorders (NPCD... hiện toàn bộ
Analysis of FMO genes and off flavour in pork
Journal of Animal Breeding and Genetics - Tập 124 Số 1 - Trang 35-38 - 2007
Kim Glenn, A. M. Ramos, Jean Pierre Bidanel
SummaryOff flavours in pork sometimes produce tastes such as sourness, fishy, metallic or other non‐typical flavours and are often caused by low pH. Loss of function mutations in flavin containing mono‐oxygenase 3 (FMO3) are known to be associated with a fishy off flavour in both chicken eggs and cow's milk and a similar autosomal recessi...... hiện toàn bộ
An improved protocol for the production of AFLPTM markers in complex genomes by means of capillary electrophoresis
Journal of Animal Breeding and Genetics - Tập 122 Số 1 - Trang 62-68 - 2005
Riccardo Papa, Michela Troggio, Paolo Ajmone‐Marsan, Francesco Nonnis Marzano
SummaryThe amplified fragment‐length polymorphism (AFLP) technology is a recently introduced method to investigate genomes of different complexity, from microbial to higher organisms. It is applied to purposes as diverse as identification of species, strain and varieties, investigation of genetic diversity within and between populations, simple and complex trait ma...... hiện toàn bộ
