Abstract

Fertility is one of the most economically important traits in both beef and dairy cattle production; however, only female fertility is typically subjected to selection. Male and female fertility have only a small positive genetic correlation which is likely due to the existence of a relatively...

Abstract

Mammalian sperm are exposed to a natural hypoosmotic environment during male-to-female reproductive tract transition; although this activates sperm motility in vivo, excessive swelling can harm sperm structure and function. Aquaporins (AQPs) is a family of membrane-channel proteins implicated in...

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

The objective of this study was the characterisation of sperm and semen from artificial insemination (AI) Holstein bulls raised in Morocco. The study was carried out on 4 046 ejaculates over 5 051 collected ejaculates between 2009 and 2013 from 34 bulls of 13 to 93 months old at Kénitra centre. The ...

AbstractFull Text

Male calves from the high value parents, bull fathers and bull dams, enter the selection for artificial insemination. After laboratory tests, the calves are taken to the center for artificial insemination, and after a stay in quarantine the are moved to a test station. At the age of twelve months...

Abstract

Predicting in vivo fertility of bull ejaculates using in vitro-assessed semen quality criteria remains challenging for the breeding industry. New technologies such as computer-assisted semen analysis (CASA) and flow cytometry may provide accurate and objective methods to improve semen quality...
