Genetic diversity and phylogenetic relationships in local cattle breeds of Senegal based on autosomal microsatellite markers [PDF]

Veterinary World, 2015
Aim: In Senegal, uncontrolled cross-breeding of cattle breeds and changes in production systems are assumed to lead to an increase of gene flow between populations. This might constitute a relevant threat to livestock improvement.

RADIOIMMUNOASSAY OF LUTEINIZING HORMONE IN THE BLOOD OF ZEBU CATTLE [PDF]

Reproduction, 1972
Summary. A solid-phase radioimmunoassay was used to measure lh in the serum of a Zebu cow and heifer during the oestrous cycle. Shortly after the onset of oestrus, serum levels of lh rose sharply to 20 to 120 ng/ml before dropping to baseline levels of about 2 ng/ml after 8 to 10 hr. Elevated lh values were also detected in mid-cycle,
