Estimates of correction factors for lactation length and genetic parameters for milk yield in buffaloes



Estimates of correction factors for lactation length and genetic parameters for milk yield in buffaloes



Arquivo Brasileiro de Medicina Veterinaria e Zootecnia 56(2): 251-257



Correction factors for milk yield at 90, 240, 270 and 305 days of lactation of buffaloes and genetic and environmental parameters for milk yield of these lactation periods were estimated. The data (1987-2001) used consisted of 3888 lactation records of 1630 buffaloes from 10 herds reared in the State of Sao Paulo. Genetic parameters were estimated by the derivative free restricted maximum likelihood method, fitting an animal repeatability model.
