ABSTRACT
The objective was to evaluate the effect of partial or total replacement of Tifton 85 hay with fresh or dehydrated spineless cactus on performance and body weight components of sheep. Thirty hair lambs, with 19 kg ± 0.35 kg initial weight, were randomly divided into five treatments, namely: Tifton 85 Hay (HA); Tifton 85 Hay + fresh spineless cactus (HAFC); Tifton 85 Hay + dehydrated spineless cactus (HADC); fresh spineless cactus (FC); dehydrated spineless cactus (DC). In addition to the spineless cactus and hay, the complete mixture contained soybean meal, mineral salt and limestone in all treatments. Animals were confined for 75 days and then slaughtered. The weight of body components was recorded. Dry matter intake, total digestible nutrients intake and voluntary water intake were higher (p 0.05) for the DC and HADC treatments. The average daily gain was 118 g day-1 and body weight at slaughter of 25.8 kg were not influenced (p > 0.05) by treatments. The cold carcass weight, rib eye area, weight and yield of the skin, liver, kidney and large intestine were higher (p 0.05) for the DC and HADC treatments. Partial or total replacement of Tifton 85 hay with fresh or dehydrated spineless cactus, in complete diets for sheep, increases the weight of the cold carcass and non-carcass components.(AU)
Objetivou-se avaliar o efeito da substituição parcial ou total do feno de Tifton 85 por palma forrageira in natura ou desidratada sobre o desempenho e componentes do peso corporal de ovinos. Foram distribuídos aleatoriamente 30 cordeiros deslanados, com peso vivo inicial de 19 kg ± 0,35 kg, em cinco tratamentos, a saber: feno de Tifton 85 (FE); feno de Tifton 85 + palma in natura (FEPA); feno de Tifton 85 + palma desidratada (FEPD); palma in natura (PA); palma desidratada (PD). Além da palma e feno ofertou-se, na forma de mistura completa, farelo de soja, sal mineral e calcário em todos os tratamentos. Os animais foram mantidos confinados durante 75 dias; decorridos esse período foram abatidos e tiveram os pesos dos componentes corporais registrados. O consumo de matéria seca, nutrientes digestíveis totais e ingestão voluntária de água foram maiores (p 0,05) para os tratamentos PD e FEPD. O ganho médio diário foi de 118 g dia-1 e o peso corporal ao abate de 25,8 kg e não foram influenciados (p > 0,05) pelos tratamentos. O peso de carcaça fria e área de olho de lombo foram menores (p 0,05) para dieta FE. A substituição parcial ou total do feno de Tifton 85 por palma forrageira (in natura ou desidratada) melhora o desempenho e as características de carcaça de ovinos.(AU)
