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...
Association of insulin-like growth factor I gene polymorphisms (IGF1/TasI and IGF1/SnaBI) with the growth and subsequent milk yield of Polish Holstein-Friesian heifers
cattle body weight insulin-like growth factors milk performance
2015/6/24
The aim of this study was to estimate potential relationships between insulin-like growth factor I gene polymorphisms (IGF1/TasI and IGF1/SnaBI) and the growth parameters of calves as well as their su...
Association of novel polymorphisms in the bovine myocyte enhancer factor 2D (MEF2D) gene with carcass traits of Polish Holstein-Friesian cattle
MEF2D gene gene polymorphism combined genotype meat contents bulls
2015/6/24
In the present study the polymorphism of the myocyte enhancer factor 2D (MEF2D) gene was analyzed as a genetic marker candidate for carcass traits in Polish Holstein-Friesian cattle. Four novel single...
Relationships among milk yield, body weight, and reproduction in Holstein and Czech Fleckvieh cows
dairy cow negative energy balance
2015/6/23
A retrospective, observational study comprised analyses of individual cow records from
a computerised herd management system. Production, body weight, and reproduction data were collected
between ...
Ovarian follicle growth dynamics during the postpartum period in Holstein cows and effects of contemporary cyst occurrence
cow postpartum ovary follicular wave
2015/6/23
The animals were assigned to three groups based on the time of the 1st ovulation: G1 (n = 9)
– the 1st dominant follicle (DF) ovulated, G2 (n = 10) – ovulation occurred on the 2nd or later follicula...
Genetic parameters of test-day somatic cell scores for the first three lactations of Polish Holstein-Friesian cattle
heritability genetic correlation somatic cell count dairy cattle
2015/6/9
Genetic parameters for somatic cell score in the first three lactations of Polish Holstein-Friesian cattle were estimated. A multiple-lactation model was applied with random herd-test-day effect, fixe...
Genetic parameters for somatic cell score in the first three lactations of Czech Holstein and Fleckvieh breeds using a random regression model
test-day somatic cell score random regression model genetic parameters Holstein cattle Czech Fleckvieh
2015/6/9
A multiple-lactation random regression model was applied to test-day somatic cell score (SCS) records from the first three lactations of Czech Holstein and Fleckvieh cows. For Holstein, the data inclu...
Heritabilities and genetic correlations of lactational and daily somatic cell score with conformation traits in Polish Holstein cattle

2015/6/9
The objectives of this study were to estimate genetic parameters for 18 currently recorded linear conformation traits in Czech Holstein cattle. The data set consisted of 78 886 first-lactating Holstei...
Immunohistochemical profile of multicentric cutaneous epitheliotropic T-cell lymphoma with generalised lymphadenopathy in a Holstein-Friesian cow: a case report
cattle cutaneous epitheliotropic lymphoma T-cell lymphoma immunohistochemistry
2015/4/16
Cutaneous epitheliotropic T-cell lymphoma with progression to superficial and internal lymph nodes and the spleen was diagnosed in a two-year-old Holstein-Friesian cow. The skin lesions included multi...
