Abstract

Previous studies have shown that the use of beef bull semen significantly reduces the rate of abortions due to Neospora caninum in artificially inseminated (AI) seropositive dairy cows. In addition, certain beef breeds could be more resistant to N. caninum infection and abortion than others. The...

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 objectives were to determine the effect of ovsynch plus postbreeding infusion treatment combined with fixed time AI on pregnancy rate in healthy Holstein cows. A total of 36 cows ageing between three and eight were used. Cows were randomly assigned to one of three treatment groups. Cows (n=12)...

Abstract

Manipulation of the reproductive tract can cause inflammatory processes in the endometrium and release of cytokines and prostaglandins. It has been shown that PGF has direct negative effects on embryonic survival and development. Treatment with nonsteroidal antiinflammatory drugs (e.g., ibuprofen ...

Abstract

Pregnancy per insemination is a major determinant of reproductive efficiency in cattle and is affected by concentrations of progesterone (P4) during early pregnancy. The relationship between pregnancy per artificial insemination (P/AI) and early luteal concentrations of P4, and repeatability of...

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...
