Effect of genotype on heat production and net energy value of a corn-soybean meal-based diet fed to growing pigs
energy utilisation genotype growing pigs heat production net energy
2015/10/9
The net energy (NE) system takes into account the metabolic utilisation of energy and has been proposed as a superior system for characterising the energy value of feeds. In growing pigs, the ineffici...
Interaction between housing system and genotype in relation to internal and external egg quality parameters
laying hen conventional cage enriched cage litter genotype egg physical measurements pore density
2015/6/9
The effect of three housing systems (conventional cages, enriched cages and litter) on egg quality parameters was evaluated in two experiments with four brown laying strains ISA Brown, Hisex Brown, Bo...
High resolution melting as an alternative method to genotype diacylglycerol O-acyltransferase 1 (DGAT1) K232A polymorphism in cattle
HRM analysis PCR-RFLP K232A polymorphism
2015/6/9
PCR-RFLP analysis is a common method for genotyping the DGAT1 K232A polymorphism in cattle. Our purpose was to develop a high resolution melting (HRM) assay in order to genotype the polymorphic allele...
Effect of genotype, age of hens and K/k allele on eggshell quality
hens laying type age genotype K/k allele eggshell quality
2015/6/9
We assessed the influence of the particular genotype, age of layers, feather growth-rate gene, and their mutual interactions on selected indicators of eggshell quality in six groups of hens of the lay...
Selection of a suitable definition of environment for the estimation of genotype × environment interaction in the weaning weight of beef cattle
environment beef cattle genetic parameters REML maximum likelihood
2015/6/5
Genotype by environment interactions for weaning weight in beef cattle were tested using several definitions of environments. Four breeds of beef cattle (Hereford, Aberdeen Angus, Beef Simmental, and ...
Effects of Border disease virus (genotype 3) naturally transmitted by persistently infected sheep to pregnant heifers and their progeny
Border disease virus abortion sheep
2015/4/8
Eight heifers pregnant between days 47 and 73 were kept together with nine healthy persistently Border disease virus (BDV)-infected sheep allowing natural contact comparable to field conditions. All h...
Genotype by environment interaction for carcass traits and intramuscular fat content in heavy Iberian pigs fattened in two different free-range systems
premium cuts intramuscular fat breeding values economic values
2014/10/24
Genotype by environment interaction (G×E) is a potential source of reduced efficiency in genetic improvement programs in livestock. The objective of the current work consisted of checking the existenc...
