Performance Of Gaur X Cattle Hybrids

The phenotype, growth performance and the reproductive status of 60 heads of male and female gaur x cattle hybrids were recorded and compared with Sahiwal-Friesian crossbred cattle. The main objectives of this experiment were to evaluate the phenotype of the hybrids, the growth potential for be...
