Hanwoo Single Nucleotide Polymorphism Whole Genome Association Carcass Traits Growth Traits
2017/3/7
A whole genome association study was conducted to identify single nucleotide polymorphisms (SNPs) with additive and dominant effects for growth and carcass traits in Korean native cattle, Hanwoo.
Analyses of genetic relationships between linear type traits, fat-to-protein ratio, milk production traits, and somatic cell count in first-parity Czech Holstein cows
Holstein cattle genetic parameters milk yield somatic cell score
2015/7/2
Genetic and phenotypic correlations between production traits, selected linear type traits, and somatic cell score were estimated. The results could be useful for breeding programs involving Czech Hol...
Relationships between milk urea and production and fertility traits in Holstein dairy herds in the Czech Republic
dairy cow reproduction probability of conception
2015/6/8
The objective of this study was to determine how the concentration of milk urea (MU) and FPCM production affect reproduction in selected Holstein dairy herds in the Czech Republic. A retrospective, ob...

fur animals fur coat inbreeding
2015/6/5
Three data sets were available: records on conformation and coat traits for the arctic fox from one farm (5 540 observations, collected between 1983 and 1997), and the same traits for the silver fox f...
A relationship between production and reproduction traits in cows of Czech Pied cattle
milk yield pedigree value Czech Pied cattle
2015/6/5
The purpose of the paper was to analyse the effect of the level of milk yield and breeding value on reproduction of Czech pied cows. In the study of cows that calved in the period 1999–2001 the result...
Single nucleotide polymorphism (SNP) in the 5?noncoding region of the bovine growth hormone receptor gene and its association with dairy production traits in Polish Black-and-White cattle
cattle GHR gene
2015/6/1
The effects of cow抯 genotype for growth hormone receptor (GHR) were determined on milk production traits of the Polish Black-and-White (BW) cattle. It was shown that GHR genotypes significantly influe...
USING CLASSIFICATION TREES IN STATISTICAL ANALYSIS OF DISCRETE SHEEP REPRODUCTION TRAITS
sheep/reproductive performance classification trees
2010/12/8
The research material covered 2-8 year-old 6,586 Polish Merino ewes. Ewes were obtained from ten flocks located in the Pomorze and Kujawy Region (Poland). The reproductive performance index (the numbe...
EVALUATION OF CROSSBRED CALF AND COW TYPES; SUBJECTIVE TRAITS
Gelbvieh crossbreeding multinomial data
2010/12/2
Data in this experiment consisted of birth weight, calving score, thickness and grade records of 600 crossbred calves. Angus, Brangus, and Gelbvieh sires were mated to purebred Hereford cows. Yearling...
