Abstract

This research was carried out to investigate the effect of different levels of forage and concentrate in the diet offered to pregnant ewes on the intake, glucose level and apparent digestibility. A study of in vivo digestibility was done to determine the intake and the apparent digestibility and blood samples were collected to determine the glucose concentration. Sixteen adult, pregnant, non- lactating, Santa Inês ewes, weighting 54.10 ± 5.89 kg, were used. The experimental design used was a completely randomized arrangement, with four treatments (10%; 20%; 30% and 40% of roughage). The intake of DM, digestible energy, metabolizable energy and digestible protein was not influenced by treatments. The apparent digestibility of DM, CE and neutral detergent fiber (NDF) was not influenced by treatments. The apparent digestibility of CP and the intake of NDF were influenced by treatments. The glucose level was influenced by treatments and the times of collection.
