Corpus luteal angiogenesis in a high milk production dairy breed differs from that of cattle with lower milk production levels
Holstein Friesian dairy cows dual purpose cows corpus luteum vascularisation capillary angiogenesis
2016/10/14
Globally, high producing, young dairy cows often have health and fertility problems such as ovarian, uterine and placental dysfunction, mastitis and impaired wound healing. These health issues can res...
Effect of the FGF2 SNP11646 on milk production and fertility traits of Holstein cattle
dairy cow fibroblast growth factor single nucleotide polymorphism linear mixed model
2016/9/1
The objective of this study was to estimate the effect of a single-nucleotide polymorphism (SNP11646) in the FGF2 (Fibroblast Growth Factor 2) gene on the deregressed proof of breeding values (DRP) of...
Genetic relationship of functional longevity with female fertility and milk production traits in Czech Holsteins
Holstein cattle genetic parameters milk yield functional traits
2015/6/24
The objectives of this study were to estimate heritabilities of and genetic correlations among longevity, milk production, and female fertility traits of Holstein cows. Fertility traits were days open...
Polymorphism identification in goat DGAT1 and STAT5A genes and association with milk production traits
milk yield fat percentage dairy goat SNP PCR-RFLP SSCP additive effect
2015/6/24
Polymorphisms of DGAT1 and STAT5A genes in Xinong Saanen and Guanzhong goat breeds were investigated. PCR-RFLP, SSCP, and DNA sequencing were used to identify three SNPs: DQ380250:g.407_408insC in the...
The association of five polymorphisms with milk production traits in Czech Fleckvieh cattle
dairy cattle PPARGC1A
2015/6/23
As part of this study, 505 Czech Fleckvieh cows were genotyped. The markers in proliferator-activated
receptor gamma coactivator 1-alpha (PPARGC1A), secreted phosphoprotein (SPP1), cytochrome P450 f...
Milk protein genes CSN1S1, CSN2, CSN3, LGB and their relation to genetic values of milk production parameters in Czech Fleckvieh
milk protein genes cattle caseins beta-lactoglobulin milk production
2015/6/2
Genotypes of milk protein genes, alphaS1-casein (CSN1S1), beta-casein (CSN2), kappa-casein (CSN3) and beta-lactoglobulin (LGB), were detected in 440 individuals of Czech Fleckvieh breed using a PCR-RF...
Correlations between milk production and kinetic variables in milk of cephalothin administered
cephalothin kinetic variables correlation coefficients
2015/2/5
The aim of the present study was to correlate the milk production and the kinetic variables in milk of cephalothin administered to goats. Twenty healthy creole goats in milk production were used. Ceph...
