Twelve West African dwarf lambs 11 to 15 months of age and weighing 7.0 to 10.0 kg were randomized into three groups. Each group was fed diets containing zero, twenty-five and fifty percent corn cobs as replacer for hay (Cynodon nlemfuensis) in maize and groundnut cake-based media. Two mates from each treatment group were later placed in individual metabolic cages for digestibility experiments. Results showed that dry matter (DM) intake, weight gain, efficiency of fed utilization and nutrient digestibility values were similar for animals on rations A (zero corn cobs, 50% hay) and B (25% corn cobs, 25% hay) which were higher than values obtained for animals on ration C (50% corn cobs, zero hay). Results obtained also suggested that 25% ground corn cobs could be successfully incorporated into the diets of West African dwarf sheep for optimal utilization.

This study aimed to evaluate the effect of replacement of ground corn by soybean hulls associated or not to whole soybean grain in the feed supplement on intake, nutrient digestibility, rumen microbial population, and fermentation parameters of growing Nellore steers grazing Brachiaria brizantha cv. Xaraés during rainy season. Were used eight castrated Nellore steers (425 ± 36 kg of body weight (BW)) fitted with ruminal and duodenal cannulas in a replicated 4 × 4 Latin square with a 2 × 2 factorial arrangement, allocated into 4 paddocks of 0.25 ha each, consisting of Brachiaria brizantha cv. Xaraés and supplemented with: (1) ground corn combined with whole soybean grain (SG); (2) ground corn without SG; (3) soybean hulls (SH) combined with SG; and (4) SH without SG. Supplement intake was no affected by SG or SH (mean 2.12 kg-1 d, P > 0.05). There were no interactions between SH and SG on DM and nutrients intake (P > 0.05). The addition of SG reduced the dry matter (DM) intake expressed as % of BW and Kg-1 d, as well forage DM, organic matter (OM), crude protein (CP), neutral detergent fiber (aNDF), and gross energy (GE) intake (P ? 0.01). Animals supplemented with SH without SG had greater digestibility of DM (74.52), OM (77.62), CP (77.51), NDF (71.93) and GE (72.90) than animals supplemented with SH with SG (DM =69.01, OM = 71.92, CP = 72.81, NDF = 66.01, GE =68.01) expressed as % (P ? 0.01). The addition of SG in the supplements declined the ruminal pH and NH3-N (P=0.02). Animals supplemented without SH without SG showed greater Entodinium counts (6.01 n x 104 ml-1, P=0.04), and SG supplementation decreased the numbers of Dasytricha, Isotricha, and ruminal total protozoa (P < 0.01). The abundance of Ruminococcus albus, R. flavefaciens, and Archaeas were higher for SH without SG supplement. Additionally, animals supplemented with SG had lower numbers of Fibrobacter succinogenes. The use of soybean hulls without whole soybean grain in the supplement may be effective to increase fiber digestibility, N retained, R. albus and R. flavefaciens in the rumen of Nellore steers grazing Brachiaria brizantha cv. Xaraés during the rainy season.

SUMMARY The effects of cassava wastewater on nutrient digestibility and rumen protozoa were evaluated in 32 Santa Inês sheep fed a diet with Tifton hay, ground corn cob, and concentrate, containing 0, 500, 1000, or 1500 mL cassava wastewater. Uncastrated sheep at an average age of 167 days and average weight of 25.3 kg were housed in individual stalls and distributed in a randomized complete design with four treatments and eight replicates. The experimental period was 70 days: 15 days for adaptation to the diets and 60 days to collect the ingredients and diets supplied. Prior to this stage, the animals were adapted to the consumption of cassava wastewater, in collective cages, for seven days. Apparent digestibility was determined by partial feces collection and by using the LIPE® external marker in 250-mg capsules. The apparent digestibility of nutrients did not differ (P>0.05) in relation to the cassava wastewater levels tested. Eleven genera of rumen protozoa were identified, and they formed a community that, except for Ophryoscolex, did not differ among the cassava wastewater treatments with respect to composition. However, Entodinium species were observed at a higher density (P<0.05) in sheep that received 1500 mL of cassava wastewater. The use of cassava wastewater in the sheep diet does not affect the digestibility of nutrients or composition of rumen protozoa; however, it causes a significant increase in Entodinium density.
