Records of 689 lactations of 225 Alpine x Gurguéia goats, progenies of 18 buck, controlled from 1988 to 1996, raised at Carnaúba Farm, Taperoá-PB, were analyzed with the objective of study environmental effects and estimate genetics parameters for Milk Production (MP) and Length of Lactation (LL). The environmental effects were analyzed by an statistical model that included buck random effects and the fixed effects of contemporary groups, type of kidding and age of dam at kidding and length lactation as […]
