Average daily gain from weaning (GMD¾12) to yearling weight (P12M) of Nellore, Guzerá x Nellore (GN), Red Angus x Nellore (RN), and Marchigiana x Nellore (MN) cattle, from a crossbreeding experiment conducted at the IAPAR Paranavaí Experimental Station, produced by artificial insemination, born between 1985 and 1997 within two annual birth seasons (January – April and July – December), were analyzed. The least squares method was utilized to study 634 observations of GMD_D12 and of P12M. Calf’s birth month was […]
