Abstract

An experiment was performed on 128 heifers (79 Holstein and 49 Normande heifers) born during four successive winters (1989-1992) and aimed at studying the effect of limiting average daily live weight gain (ADG) during two successive winters on performance and longevity when heifers first calved at...

Abstract

Background: Low birth weight and postnatal growth restriction are the most evident symptoms of dwarfism. Accompanying skeletal aberrations may compromise the general condition and locomotion of affected individuals. Several paternal half-sibs with a low birth weight and a small size were born in...

Abstract

Feet and leg problems have a major effect on the well-being and lifespan of the dairy cow and thus are economically important to the dairy farmer. Apart from approaches using genetic selection for classical traits from conformation scoring, attempts for genetic improvement can be based either on...

Abstract

Background: In national evaluations, direct genomic breeding values can be considered as correlated traits to those for which phenotypes are available for traditional estimation of breeding values. For this purpose, estimates of the accuracy of direct genomic breeding values expressed as genetic...

Abstract

The follicle-stimulating hormone (FSH) acts on the sertoli cells in the seminiferous tubules of the testis and regulates spermatogenesis up to the secondary spermatocyte stage. Allelic and genotypic frequencies of bovine follicular stimulating hormone (exon III) gene were studied for 83 animals...

Abstract

This study investigates the scoring distribution of foot and leg linear type traits, rear legs (side and rear view), and foot angle of Holstein and Jersey dairy bulls provided by semen companies in Brazil. Registers of 392 Holstein and 92 Jersey bulls were found in the websites of these companies,...

Abstract

We have previously shown that Holstein cows selected for their homozygous favorable ("fertil+") or unfavorable ("fertil-") haplotype at one quantitative trait loci (QTL) of female fertility located on chromosome 3 (QTL-F-Fert-BTA3) had a different success rate 35 and 90 days after the first ...

Abstract

The objective of this study was to determine the association between ambient temperature and humidity, vaginal temperature, and automated activity monitoring in synchronized cows. Lactating Holstein cows (n=641; 41.5±9.4 kg of milk/d) were fitted with leg-mounted pedometers, resulting in 843...

Abstract

Data from 96 Holstein Friesian cows on a commercial dairy farm were used to investigate whether body condition and serum levels of nonesterified fatty acids (NEFAs) postpartum (pp) affect progesterone (P4) levels, estrous activity, and fertility in dairy cows. The examination period started 14 days ...
