AbstractFull Text

Reproductive inefficiency is one of major challenges affecting dairy farming in Kenya. This is partly caused by poor estrus detection, delayed determination of unsuccessful artificial insemination (AI) and sub-optimal calving to conception interval. Blood levels of progesterone hormone (P4) are a...
