This work evaluated the effect of feeding frequencies on performance, ingestive behavior and carcass characteristics of fedlot lambs. Eighteen non-castrated Santa Inês crossbreed lambs, with initial live weight of 22.79 ± 4.28 kg were used in the experiment. The animals were confined for 56 days in collective pens in a slotted floor sheep barn. The animals were randomly distributed, according to the feeding frequency: once, twice and three times/day. The diet (16.7% of CP and 70.3% TDN) was the same […]

The objectives of the present study were to characterize nictemeral pattern of ruminal pH and feed behavior of dairy goats fed diets presenting different ratios of roughage:concentrate. Five non pregnant non lactating goats, ruminally cannulated, and averaging 58 kg were used during the five experimental periods. A 5×5 Latin square was used to evaluate five treatments consisted of roughage to concentrate ratio of 100:0, 80:20, 60:40, 40:60 e 20:80. Diets were fed every 6h in order to reduce ruminal pH […]
