Abstract

Three genetic groups of Holstein-Friesian dairy cows were established from within the Moorepark (Teagasc, Ireland) dairy research herd: LowNA, indicative of the Irish national average-genetic-merit North American Holstein-Friesian; HighNA, high-genetic-merit North American Holstein-Friesian;...

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

The incidence of and risk factors associated with calving assistance and dystocia in pasture-based dairy herds were determined from analysis of 152,641 records of full-term calvings from Holstein-Friesian dams served by artificial insemination (AI) sires of seven breeds in herds of 20 calvings or...

Abstract

The objective was to identify herd-level indicators expressed as a proportion of sampled animals with increased nonesterified fatty acids (NEFA) or β-hydroxybutyric acid (BHBA), or decreased calcium in wk -1 and wk +1 relative to calving that were associated with herd-level incidence of retained...

Abstract

The somatotropic axis is a key metabolic pathway during transition from late pregnancy to early lactation in dairy cows. The first objective of this study was to determine the feasibility of selecting cows with persistent differences in total insulin-like growth factor 1 (IGF-1) concentration by...

Abstract

This study aimed to evaluate the effects of animal category (early two years old primiparous, three years primiparous and multiparous cows) on interval duration between the onset of breeding season (BS) and conception, number of inseminations per female and pregnancy rate at the end of BS. Animals...
