The experiment was carried out at Sheep Production Department, Universidade de Marília-SP, to evaluate the effect of rations with three energy levels fed to Suffolk lambs grown in creep feeding, on performance and carcass traits. At birth, lambs were identified, weighed and, then, randomly allotted to the treatments, with 12 replications for different energy levels. Lambs fed isoproteins rations ad libitum, twice a day, and orts were daily recorded. Lambs were weighed at each 14 days and stayed with their […]

Thirty two Canchim suckling calves, maintained on rotational grazing system of Brachiaria brizantha cv. Marandu, were divided in three groups corresponding to three evaluated treatments: control (without creep-feeding); SAL5 (addition of 5% of NaCl to concentrate fed in creep-feeding); and SAL10 (addition of 10% of NaCl to concentrate fed in creep-feeding). Feeding in a creep-feeding system lasted 90 days, divided in three subperiods of 30 days. The body weight gain was greater in the subperiods 1 and 2 for SAL10 […]

Lambs performance fed on creep feeding and fedlot were evaluated at two experiments. In the first experiment, thirty two 3/4 Suffolk lambs were fed on creep feeding, weaned at 56 days of age and, after, were confined. Lambs were fed four different treatments: 1. without supplemmentation; 2. supplemmentation with ground corn and soybean meal; 3. ground corn, soybean meal and 15% alfalfa hay; 4. ground corn, soybean meal and 30% alfalfa hay. After weaning, lambs that received concentrate supplemmentation were […]

Twenty 3/4 Suffolk male lambs were fed ground and pelleted diets and slaughtered at 26 and 28 kg of liveweight. Diets were isoprotein (21% CP) and isoenergetic (2.9 Mcal ME/kg DM). Lambs had free entrance on creep feeding, staying with their mothers until reaching slaughter weight. Pelleted diet resulted in higher hot dressing-out percentages (54.18% for pelleted diet and 52.04% for ground one) and higher true dressing-out percentages (58.37% for pelleted diet and 56.66% for ground one). Hot and cold […]

ABSTRACT – Two nutrition programs were tested on Mangalarga Marchador foals: TA: supplementation with concentrate from 2 to 12 months of age and TB: supplementation from weaning to 12 months of age. Animals from TA and TB were kept in either one of the available feedlots: one of coast cross (Cynodon dactylon x Cynodon nenfluensis) + Cynodon nenfluensis grasses and the other of coast cross (C. dactylon x C. nenfluensis) only. Monthly the animals were weighed (W) and measured: height […]
