Ewe-lambs relationship in Morada Nova breed under three energy levels at the end of gestation

The present work was carried out with the objective to evaluate the effects of different energy levels offered in the final third of gestation on the ewe-lambs behavior of animals from the Morada Nova breed. The experiment was divided into three treatments - three groups of eight ewes, fed isoprotein diets containing different energy levels (2.0. 2.4, and 2.8 Mcal ME/kg DM), with eight replicates each. There was effect of the treatment on the maternal behavior evaluated variables (vocalization, act of smell and lick the lambs and the position of the ewe - stand up or lying), in the ewes, but no difference was observed for the filial behavior (position of animal, time from the birth to the first time that the animal was up, time from the birth to the first sucking and total time sucking) of the lambs. The mobilization of reserves or the direct carrying of nutrients of the diet for normal fetal growth, in the groups fed with diets containing 2.0 and 2.4 Meal ME/kg DM, minimized, the possible effects on the filial behavior of lambs. The mobilization of reserves or direct carry of nutrients of the diet for normal fetal growth, in the groups fed with diets. containing 2.0 and 2.4 Meal ME/kg DM, minimized the. possible effect on, the filial behavior of lambs. Despite the interference in their relationship with, the kids, ewes Morada Nova attained to keep, the conditions of the lambs unchanged in all treatments.
