| The aim of this study was to evaluate the metabolic profile of the use of soyabean hulls associated with two sources of non-protein nitrogen (NPN) on the finishing of feedlot lambs. Eighty crossbred Suffolk non-castrated lambs aging 69±6 days and weighing 23.11±1.78 kg were used. Lambs were randomly allocated into 4 experimental groups according to the NPN source: conventional urea (1%); protected urea; 1% protected urea + 0.5% conventional urea; and a control group, which did not receive urea supplementation. Blood samples were collected weekly to determine the plasma concentrations of urea, albumine, γ-glutamiltransferase (GGT), calcium and phosphorus. The control group had higher average daily gain and final weight than protected urea and protected urea... |

| The objective of this work was to evaluate the effect of insulin alone or in association with equine chorionic gonadotropin (eCG) on the fertility of postpartum beef cows subjected to synchronization. A total of 340 cows was subjected to fixed time artificial insemination. In the trial 1, the cows were subjected to temporary weaning (TW), while in the trial 2 the same protocol was tested without TW. The addition of an insulin injection to a progesterone/eCG-based protocol without TW increased the pregnancy rate of beef cows with body condition score (BCS) equal to or lower than 2.5. Insulin had no effect on cows submitted to TW or with BCS equal to or higher than 3.0. |
