Abstract

An experiment was carried out at Estação Experimental de Zootecnia de Sertãozinho, to study the effects of feed supplementation during the pre (creep feeding) and postweaning growth of nellore females. The sample was composed of 176 animals, born from august to november (1983-1985) and were allotted into 4 treatments: "C + S" (creep feeding and postweaning supplementation); "C + P" (creep feeding); "P + S" (postweaning supplementation) and "P + P" (solely pasture). The effects of these treatments were observed on liveweight corrected for 210 (P210); 390 (P390) and 550 (P550) days and on daily gains between those ages. The creep feeding supplementation was composed of 80% ground corn and 20% cotton seed meal with 0.328kg/head/day of consumption. During postweaning phase supplemented animals received 9.900kg/day of corn silage plus 0.694kg/head/day of cotton seed meal. The "C + S" and "C + P" animals were heavier than*the "P + S" and €P + P" in P210 ( + 13.750kg), P390 ( + 11.400kg) and P550 ( + 9.730kg). The €œC + S€ treatment animals showed higher P390 ( + 45.980) and P550 (+ 23.590) when compared to €œP + P€. The €œP + S€ treatment animals also showed a higher P390 ( + 30.370) and P550 ( + 10.180) when compared to €œP + P€.
