Individual Heterosis and Breed Effects for Postweaning Performance and Carcass Traits in Four Breeds of Swine
Individual heterosis and direct and maternal breed effects for postweaning average daily gain (ADG), off-test age (AGE) and probed backfat thickness (BF) were estimated from data on 1,664 pigs produced in a complete diallel mating system involving the Duroc, Yorkshire, Landrace and Spotted breeds. The same genetic parameters were estimated for various carcass traits by analyses of data collecte...
متن کاملCSN1S1 Gene: Allele Frequency, and the Relationship with Milk Production Traits in Three Indigenous Cattle Breeds and Holstein
CSN1S1is one of the major genes encoding milk proteins of mammals. In this study we determined allele frequencies of CSN1S1-5` flanking region as well as exon 17 variants and their effects on milk traits in three indigenous cattle breeds Mazandarani, Golpaygani (Bos indicus) and Sarabi (Bos taurus) and Holstein cattle in Iran. CSN1S1*B variant was nearly fixed in Holstein but ranged from 0.40 t...
متن کاملMapping of quantitative trait loci for carcass traits in a Japanese Black (Wagyu) cattle population.
To detect quantitative trait loci (QTL) that influence economically important traits in a purebred Japanese Black cattle population, we performed a preliminary genome-wide scan using 187 microsatellite markers across a paternal half-sib family composed of 258 offspring. We located six QTL at the 1% chromosome-wise level on bovine chromosomes (BTA) 4, 6, 13, 14 and 21. A second screen of these s...
متن کاملQuantitative trait loci for body weight and carcass traits in Japanese quail
Body weight (BW) and carcass traits are complex and important economic traits that may benefit from the implementation of MAS. The objective of the current study was to identify QTL associated with BW and carcass traits in an experimental half-sib cross of Japanese quails selected for BW at 4 weeks of age. Body weight and carcass traits were measured in the F2 population. Total F2 individuals a...
متن کاملWhole genome scan to detect quantitative trait loci for conformation and functional traits in dairy cattle.
A granddaughter design was used to locate quantitative trait loci determining conformation and functional traits in dairy cattle. In this granddaughter design, consisting of 20 Holstein Friesian grandsires and 833 sons, genotypes were determined for 277 microsatellite markers covering the whole genome. Breeding values for 27 traits, regarding conformation (18), fertility (2), birth (4), workabi...
