Physiological Constraints
Reproductive failure leads to low productivity in cows. In this module we shall cover more common causes of reproductive failure. Lactational anoestrus When oestrus is not manifested in a cow during lactation for an extended period, this is termed Lactational...
Reproduction in genetic Improvement
Embryo transfer techniques Embryo transfer is the process in which a breeder allows a cow to become temporarily pregnant, recovers the embryo in early pregnancy, and transfers it to the reproductive tracts of another cow to complete gestation. This section of the...
Factors influencing efficiency of production
Nutrition Inadequate nutrition is a major constraint to productivity of cattle in SSA. Nutrition stress can influence a cow in the following ways: cow fertility during the service period can be lowered by poor nutrition low energy content in the feed results in low...
Cycle of reproduction
Most cattle in SSA breed all year round. It is important to understand the basics of the reproductive stages so that management can be applied to attain high productivity. We have divided the life of the cow in four cycles. It is important to understand these cycles...
