An investigation was conducted to find out how diet formulation of chickpea grains (CHPE) rather than soybean meal and barely grain affected the performance, blood metabolites, carcass, and meat quality features of Awassi lambs. Thirty lambs, with an average age of 73 ± 0.85 days and an initial body weight of 21.0 ± 1.29 kg, were randomly assigned into one of three diets, with 10 lambs per treatment diet. The diets were designed to replace a portion of the barley grain and soybean meal and included no CHPE (CON), 7.5% CHPE (CHPE7.5), and 15% CHPE (CHPE15). Lambs were individually housed, fed every day, and weighed every two weeks to measure performance characteristics over the 60-day study period. Four lambs per treatment were chosen at random on day 42 to participate in an N balance study and assess diet digestibility. All lambs were slaughtered at the termination of the trial period to measure the features of the carcass characteristics and meat quality. As the amount of CHPE included in the diets increased, the cost of diets reduced. As the amount of CHPE in the diets increased, so did the intake of ether extract (EE). The CON group's cost per kilogram of increase was higher (P = 0.017) than that of the CHPE7.5 and CHEP15 groups. The digestibility of EE was higher (P = 0.024) in the CHPE15 diet as opposed to the CHPE7.5 and CON diets. The various treatments did not impact blood metabolites, carcass features, or meat quality. Therefore, the present study suggested that chickpeas might be added to the diets of finishing lambs up to 15% of dry matter.
本研究旨在探究不同的鹰嘴豆颗粒（CHPE）饲粮配方（而非大豆粉和大麦颗粒）对育肥期安哥拉羊的生产性能、血液代谢物、胴体和肉质特性的影响。30 只羔羊，平均年龄为 73±0.85 天，初始体重为 21.0±1.29kg，随机分为 3 种饲粮组，每组 10 只。饲粮设计用于替代部分大麦颗粒和大豆粉，包含无 CHPE（CON）、7.5% CHPE（CHPE7.5）和 15% CHPE（CHPE15）。羔羊单独饲养，每天喂食，每两周称重一次，以在 60 天的研究期间测量生产性能特征。在第 42 天，每个处理组随机选择 4 只羔羊参与氮平衡研究和评估饲粮消化率。所有羔羊在试验期末被屠宰，以测量胴体特性和肉质特征。随着饲粮中 CHPE 含量的增加，饲粮成本降低。随着饲粮中 CHPE 含量的增加，乙醚提取物（EE）的摄入量也增加。CON 组每公斤增重的成本（P=0.017）高于 CHPE7.5 和 CHEP15 组。与 CHPE7.5 和 CON 饲粮相比，CHPE15 饲粮中 EE 的消化率更高（P=0.024）。不同处理组对血液代谢物、胴体特征或肉质没有影响。因此，本研究表明，鹰嘴豆可添加到育肥羔羊饲粮中，最高可达干物质的 15%。
