Heterosis in the lactation curves of Girolando cows with emphasis on variations of the individual curves

Heterosis in the lactation curves of Girolando cows with emphasis on variations of the individual curves

Linear and nonlinear models were used to evaluate the effect of heterosis on the components of the lactation curves of different crossbred groups of cows from Girolando cattle. Data consisted of 233,587 test-day milk yield records from 33,995 primiparous cows from 1998 and 2014. The Wood’s linear mo...
