Stochastic simulation of the influence of insemination on the estimation of breeding value and its reliability
beef cattle breeding value connectedness reference sires reliability stochastic simulation
2015/6/4
Insemination is used less commonly in the population of beef cattle than in dairy cattle. As a consequence, herds are genetically isolated and their comparison is difficult. The objective of the paper...
Breeding value evaluation in Polish fur animals: Estimates of (co)variances due to direct and litter effects for fur coat and reproduction traits
arctic fox fur coat traits genetic parameters normal probability scale transformation reproductive traits
2015/6/2
5 540 records of the arctic fox fur coat and reproductive traits collected in 1983–1999 were studied. The analyzed traits were: body size (BS), colour type (CT), colour purity (CP), coat density (CD),...
Breeding for sustainability: Effect of breed on cultural energy expenditure of lamb production
cultural energy sustainability breed, sheep Texel Columbia Suffolk
2015/6/2
Two-year data from terminal study conducted to evaluate post-weaning growth and carcass traits of Texel, Suffolk and Columbia sired offspring were used to evaluate the effect of breed on cultural ener...
The use of performance test parameters for selection of gilts before their placement into breeding
gilt growth carcass value backfat thickness lean meat content body condition
2015/6/2
The objectives of the paper were to evaluate carcass value in reared gilts on the basis of carcass analysis during the station test of purebred progeny of pigs and ultrasonically with Sonomark-100 or ...
Breeding value evaluation in Polish fur animals: Estimates of direct heritability and portion of litter variation of fur coat and reproduction traits
arctic fox fur coat heritability
2015/6/1
The study presents estimates of heritability for fur coat and reproduction traits in arctic and silver foxes kept on Polish farms. The estimates of variance components were calculated using the DFREML...
Genetic gain, increase in inbreeding rate and generation interval in alternatives of Pinzgau breeding program
Pinzgau breed gene flow genetic gain generation interval inbreeding milk
2015/6/1
The aim of this paper was to analyse alternatives of Pinzgau breeding program. Alternatives were optimised for genetic gain of selection index composed of parameters of milk efficiency traits and incr...
The effect of carnitine on hatching rate and metabolic profile of blood in breeding layers
layers; L-carnitine; reproduction; haematological and biochemical parameters
2015/6/1
We examined the effect of orally administered L-carnitine (at a dose of 30 mg per kg of feeding mixture) on egg hatching and some haematological and biochemical parameters of blood plasma in COBB 500 ...
Effects of season on plasma progesterone profiles in repeat breeding cows

2015/5/25
Twenty eight (60.9%) and 18 (39.1%) cows were followed in summer (June–August)
and winter (December–February), respectively. In the summer season, the total progesterone concentrations were

Genome Wide Association Studies Using Multiple-lactation Breeding Value in Holsteins
Single Nucleotide Polymorphism Milk Production Traits Lactation, Holstein
2016/5/18
A genome wide association study was conducted using estimated breeding value (EBV) for milk production traits from 1st to 4th lactation. Significant single nucleotide polymorphism (SNP) markers were s...
The behaviour and productivity of water buffalo in different breeding systems: a review
