Resumo: |
Sheep farming in northeastern Brazil is characterized as a sideline subsistence, requiring technologies that provide better productivity of these animals. In this aspect, called alternative food may to some extent improve the nutrition and animal nutrition. Thus the cassava, a liquid product resulting from the pressing of manioc, may be included in the diet of small ruminants as a food energy. Therefore the objective of this study was to evaluate the effect of adding different levels of cassava in the diet of sheep on consumption, performance, carcass characteristics of lambs Santa Inês feedlot. The experiment was conducted in an experimental field of Embrapa Coastal Tablelands, located in the municipality of Frei Paulo - SE. We used 32 lambs uncastrated Santa Ines with average weight of 24.76 kg and average age of 167 days. Diets were formulated in relation 70% forage and 30% concentrate to meet nutritional requirements. All treatments were Tifton 85 hay (Cynodon spp.), Grounded maize (Zea mays) and concentrated differing by the inclusion of cassava in growing levels: 0 ml, 500 ml, 1000 ml and 1500 ml Manipueira. DM intake (% BW, kg/day and g/kg PV0, 75), the performance and carcass characteristics were not affected by treatments (P> 0.05), but water consumption was affected by the addition of cassava (P<0.05). The addition of 500mL from cassava reduces the water consumption of the lambs. The dry matter intake was not altered with the addition of cassava at any level studied. The inclusion of cassava wastewater in the diet of sheep not altered nutrient intake, weight gain and quantitative features of the carcass, however, the addition of cassava modified water consumption of animals that received the cassava wastewater. |
