Parametric correlation functions to model the structure of permanent environmental (co)variances in milk yield random regression models.

Journal of dairy science - 1 Sept 2009

Bignardi A B, El Faro L, Cardoso V L, Machado P F, Albuquerque L G

Abstract excerpt

The objective of the present study was to estimate milk yield genetic parameters applying random regression models and parametric correlation functions combined with a variance function to model animal permanent environmental effects. A total of 152,145 test-day milk yields from 7,317 first lactations of Holstein cows belonging to herds located in the southeastern region of Brazil were analyzed. Test-day milk...
