Eighteen animals with an initial age of 21 months and a mean weight of 211.7 kg were placed into three groups according to the following alimentary regimens: feed ad libitum, feed restricted to 20 % dry matter, and feed restricted to 40 % dry matter. In the feedrestriction phase, the nutrient intake decreased (P<0.001)with an increase in the restriction level. As a consequence, the observed decrease in ingestion and serum concentrations of total protein, albumin and globulin, urea, glucose, calcium, and phosphorus were inversely proportional (P<0.001) to the restriction level. Significant differences in the nutrient intake and serum concentration were not observed in the realimentation phase (P<0.05). When animals in the control group reached the end of the feed-restriction phase, their weights (P<0.05) were similar to those in the 20 % restricted group, and both obtained a final weight that was greater than that of animals in the 40 % restricted group. In the feed-restriction phase, the control group had a similar mean daily weight gain (P>0.05) to animals in the 20%restricted group and (P<0.05) 40 % restricted group. However, in the realimentation phase, the 40 % restricted group obtained greater weight gain rates (P<0.05), better food conversions, and partial compensatory gains. In particular, none of the restricted groups reached the final weight of the control group. In the feed-restriction phase, ingested nitrogen, nitrogen excreted in urine and feces, nitrogen balance and retained nitrogen decreased (P<0.05) with an increase in the restriction level. In the realimentation phase, none of the nitrogen balance variables were influenced by the restriction level (P<0.05). Females in the 40 % restricted group presented better food conversion rates and greater weight gains in the realimentation phase. Based on the animals’ compensatory weight gain, a feed-restriction rate of 20 and 40% can be adopted as a nutritional management practice for prepubescent Sindi females.Submitted by Santiago Fabio (fabio.ssantiago@hotmail.com) on 2013-11-12T20:02:43Z No. of bitstreams: 1 22222.pdf: 165394 bytes, checksum: 8441acb2777d5c9c9bf4a25e201e1e57 (MD5)Approved for entry into archive by Rodrigo Meirelles (rodrigomei@ufba.br) on 2013-11-13T17:17:00Z (GMT) No. of bitstreams: 1 22222.pdf: 165394 bytes, checksum: 8441acb2777d5c9c9bf4a25e201e1e57 (MD5)Made available in DSpace on 2013-11-13T17:17:01Z (GMT).
