Genetic parameters and genetic trends for production traits in dairy Gir cattle

Genetic parameters and genetic trends for production traits in dairy Gir cattle

ABSTRACT: The objective of this research was to estimate genetic parameters and genetic trends (GT) for 305-day milk yield (MY305) and 305-day fat yield (FY305) of purebred Dairy Gir animals of the National Dairy Gir Breeding Program. The restricted maximum likelihood method was used in an animal mo...
