| This study evaluated body fat, protein and energy contents and nutritional requirements for body weight (BW) gain of lambs in tropical semiarid conditions. Thirty-two castrated Santa Inês 3-to-4-month old lambs (initial BW: 15.8 kg ± 1.4 kg) were used. Eight lambs were initially slaughtered to serve as the reference for initial body weight composition. The remaining 24 animals were placed in a randomized block with three treatments and eight replications. Each one of the eight experimental blocks consisted initially of three 15 kg lambs to which treatments (daily supplement levels: 0.0, 1.0, and 1.5% of body weight of a corn, soybean and minerals concentrate mixture adjusted for a daily 200 g BW gain at 1.5% level) were randomly assigned. As one of the... |

| It was evaluated four levels of silk flower (Calotropis procera S.W.) hay (SFH) as a substitute of sorghum (Sorghum bicolor) hay (SBH) in diet for lambs. Nutritional value of silk-flower hay was determined based on aparent digestibility and on metabolic, productive and economical performance of Santa Inês lambs. It was used twenty-four castrated males at 15.72 ± 1.92 kg body weight randomly distributed in four diets with silk-fklower and sorghum hay ratios (100:0, 66:33, 33:66, 0:100), and supplemented with a concentrate mixture based on 50% roughage:50% concentrate (weight/weight). Increase in the levels of silk-flower hay in the diet reduced weight gain and nutrient intake and it increased feed conversion and digestibility coeficients of all the... |
