摘要

本研究的目的是评价半干旱环境下饲喂不同日粮的受限Santa Inês羊的生产性能和胴体特性。试验选用20只5±0.5月龄、27±2.0 kg的全羊,分别饲喂脱脂豆粕和富含蛋白质的仙人掌粕两种不同的饲粮,为期72 d。对不同日粮、消耗量、产量、胴体特性、形态计量指标和食用成分进行了评价。试验设计为随机分组,2个处理,10个重复。使用Statistical analysis System [SAS]®(1999),采用5%概率水平的t检验对生产性能数据和胴体性状进行方差分析和均值比较。因此,与使用脱脂豆粕相比,使用乳化棕榈饲料蛋白饲喂Santa Inês公羊羔被证明是一种极好的蛋白质来源,因为生产性能和胴体特性的结果是相似的,建议使用这种替代来源,因为它具有最佳的效益-成本比。

Performance and carcass characteristics of Santa Inês lambs fed different protein sources
The objective of this study was to evaluate the productive performance and carcass characteristics of confined Santa Inês sheep, fed different diets, in a Semiarid environment. Twenty whole sheep with 5 ± 0.5 months of age and 27 ± 2.0 kg were used, receiving two different diets for 72 experimental days, one composed of defatted soybean meal and the other of protein-enriched cactus meal. They were evaluated for different diets, consumption, production, carcass characteristics, morphometric measures and edible components. The experimental design was in randomized blocks with two treatments and 10 replications. Performance data and carcass characteristics were evaluated by analysis of variance and means compared by t test at 5% probability level using Statistical Analysis System [SAS]® (1999). Thus, the use of emulsified palm forage protein in the feeding of Santa Inês male lambs proved to be an excellent protein source when compared to the use of defatted soybean meal, since the results of performance and carcass characteristics were similar, being the use of this alternative source advised as it presents the best benefit-cost ratio.
