Evaluation of genetic parameters for lactation persistency in siboney cows with random regression models

Show other versions (1)

Genetic parameters and genetic correlations, were estimated for five persistency of lactation measures, using a random regression model with Legendre polynomials. Data consisted of test-day yields (PDC) for 17,034 first lactations of 2,086 Siboney cows (5/8 Holstein 3/8 Cuban Zebu) for calvings from 1995 through 2003 in 50 dairy herds.
