Abstract/Description
Assesses reproductive performance, body weight & live weight, pre-weaning growth, and viability of progeny sired by various unrelated breeds which are representative of the Sanga X Sanga, Sanga X Zebu, Bos taurus X Sanga, Bos taurus X Zebu, and Bos taurus X Bos taurus crossbred groups. Measures the influence of sire breed on calf birth and weaning weight and viability to weaning. Estimates heterosis levels for the range of performance traits.
