Abstract

4505 cows were inseminated with semen from Normande, French Holstein or German Holstein bulls, diluted with Biociphos diluent (in which egg yolk is replaced by soya milk and lecithin), or with Tris or laiciphos diluents. Sperm motility was significantly higher for up to 24 h after dilution for...

Abstract

A vaginal speculum examination of a 17-month-old Holstein heifer with a history of repeated artificial insemination (AI) failures via the cranial vagina revealed the presence of an intact hymen (imperforate hymen) beyond the external urethral orifice, which resembled the vaginal wall. An...

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

Our previous research demonstrated that milk production of early lactation dairy cows benefits from postruminally delivered B vitamins in addition to those supplied in rumen microbes. In this study, our objective was to determine effects of supplementation of a complex of ruminally protected B...

Abstract

Sex preselection by flow sorting of X- and Y-sperm has been proven to be an efficient and economically feasible strategy for use in Holstein dairy cow breeding, and previous reports have demonstrated the feasibility of altering the sex ratio in buffalo species by using sexed semen in either ...

Abstract

Holsteins are the most numerous dairy cattle breed in North America and the breed has undergone intensive selection for improving milk production and conformation. Theoretically, this intensive selection could lead to a reduction of the effective population size and reduced genetic diversity. The...

Abstract

61 Holstein cows were divided into 2 groups. Group A were inseminated if oestrus was observed before 60 days post partum. Group B were inseminated only after 60 days post partum. Only 57% of the cows in group A were inseminated before 60 days post partum. Compared with group B, cows inseminated...
