| This study aimed to evaluate the digestibility and nitrogen balance (NB) of lambs fed sugarcane hydrolyzed under different conditions. Fifteen Ile de France lambs at, on average, 23.5kg of body weight were evaluated. Treatments were: in natura sugarcane (IN), sugarcane hydrolyzed using 0.6% calcium oxide (CaO) under aerobic condition (AER), and sugarcane hydrolyzed using 0.6% CaO under anaerobic condition (ANA). Therefore, a completely randomized design was constituted with five replicates per treatment. Treatments were supplied to animals along with concentrate. Both hydrolysis conditions aimed to alter the sugarcane fermentation pattern, therefore improving fiber digestibility. Lambs were housed in individual pens and fed with diet allowing 10% of... |

| Abstract Legume silage can increase the forage quality of the diets as well as supply it with nitrogen, calcium and phosphorus. The objective was to evaluate the intake, apparent digestibility, rumen fermentation and nitrogen efficiency in sheep fed a tropical legume silage with or without concentrate. Twelve crossbred sheep with an average initial body weight of 32.2 ± 1.26 kg, with six animals cannulated in the rumen were distributed into four 3 × 3 Latin squares. The treatments were 1) Stylosanthes silage without concentrate (StS), 2) Stylosanthes silage with concentrate (StS+C), and 3) corn silage with concentrate (CS+C). StS diet showed lowest intake, except for neutral detergent fiber (NDF). The diets StS+C and CS+C showed similar intake of dry... |

| The aim of this study was to evaluate the performance, ingestive behavior and carcass traits of crossbred Dorper x Santa Inês lambs fed rations containing soybean cake. Twenty-four lambs (4 months of age and 24.3 ± 3.1 kg BW) were used in a completely randomized design with four treatments and six replicates. Treatments were the inclusion of 50, 100 or 150 g kg-1 of soybean cake in the ration, on a DM basis, and a control diet without this ingredient. Rations were offered ad libitum for 75 days and the lambs were slaughtered at 35 to 40 kg BW. Dry matter intake reduced linearly and the average daily gain had a quadratic response to the soybean cake levels, also decreasing with the addition of this ingredient. The time spent feeding increased and the idle... |
