How to pick breed for semen extraction
Matching genotype to phenotype: One should ensure that the desired crossbreed can survive or easily adapts to the prevailing environment and is productive.
It is important to note that high-yielding animals can be reared but will require intensive management that comes with huge financial requirements to ensure the desired outputs are realised.
However, in situations where a smallholder farmer is keen on undertaking AI services, then one must consider the prevailing environment as well as the production systems in place before selecting the desired bull’s genetic material.
Dystocia: This is a condition commonly associated with difficulties in calving. The common cause of dystocia is a small-framed cow trying to give birth to a large calf. For example, the common Small East African Zebu, which is typically small-framed inseminated with Holstein Friesian or the improved Kenyan Boran semen would be recipe for disaster.
However, the Boran x Angus cross would pose no difficulties in calving for a Boran cow.
