Phenotypic and genetic trends in some economic traits in buffaloes






Indian Journal of Dairy Science 39(3): 328-329

Phenotypic and genetic trends in some economic traits in buffaloes

Data from 180 buffaloes sired by 28 bulls in 1976-1982 were analysed. Phenotypic trends were estimated from the weighted regression of yearly means for traits on time.
