摘要

本实验的目的是评估用葫芦巴籽粉(FSM)部分或完全替代棉籽粉(CSM)对生长羔羊的化学成分、体外瘤胃发酵、生长性能和经济效益的影响。将 32 只体重为 42±0.7 千克、生长期为 210±7 天的雄性奥西米羔羊随机分为 4 个实验组,每组 8 只。羔羊饲喂四种日粮,其中含有 40% 的苜蓿和 60% 的精饲料混合物。用 0 %(FSM0;对照处理)、50 %(FSM50 处理)、75 %(FSM75 处理)或 100 %(FSM100 处理)的 FSM 代替棉籽粕。实验持续了 105 天,其中 15 天为适应期,90 天为测量期。替代物对日粮的粗蛋白(CP)和总能(GE)没有影响。但是,CSM 和 FSM 的单个氨基酸和多酚类物质的浓度有所不同。含有 FSM 的日粮体外甲烷产量(P=0.024)降低了 30-41.1%,养分降解率(P<0.05)也降低了 30-41.1%。饲喂 FSM50 日粮(1.68 千克 DM)的羔羊的 DM 采食量最高(二次效应,P<0.001),其最终体重(65.5 千克)(二次效应,P=0.045)、总增重(22.6 千克)(二次效应,P=0.034)和日增重(251.1 克)(二次效应,P=0.033)也最高。FSM50 处理的羔羊有机物消化率更高(∼ 69.4 %)(二次效应,P=0.016)(P<0.05)。与对照组相比,用 FSM 替代 CSM 可线性提高(P=0.024)血液抗氧化活性,降低血液胆固醇(P=0.022)、甘油三酯(P=0.035)和高密度脂蛋白(P=0.034)。净收益相对百分比最高的是 FSM50 日粮(131%),最低的是 FSM100 日粮(92.9%)(P=0.011)。由此得出结论,在生长羔羊的日粮中,可以用 50 % 的 FSM 替代 CSM,以提高羔羊的生产性能和经济效益。

Effect of replacing cottonseed meal with fenugreek seed meal on feed intake, digestibility, growth, blood parameters and economics of fattening lambs

The aim of the present experiment was to evaluate the partial or complete replacement of cotton seed meal (CSM) with fenugreek seed meal (FSM) on chemical composition, in vitro ruminal fermentation, the growth performance and economic efficiency of growing lambs. Thirty-two male Ossimi lambs weighing 42±0.7 kg, and 210±7 d were divided randomly into four experimental groups of eight lambs each. Lambs were fed four diets containing 40 % berseem clover and 60 % concentrate feed mixture. Cotton seed meal was replaced with FSM at 0 % (FSM0; control treatment), 50 % (FSM50 treatment), 75 % (FSM75 treatment) or 100 % (FSM100 treatment). The experiment was lasted for 105 d consisting of 15 d for adaptation and 90 days for measurements. The replacement did not affect crude protein (CP) or gross energy (GE) of the diets. However, the concentrations of individual amino acids and polyphenols differed between CSM and FSM. Diets containing FSM reduced the in vitro methane production (P=0.024) by 30–41.1 %, and nutrient degradability (P<0.05). The highest DM intake was observed (quadratic effect, P<0.001) with lambs fed the FSM50 diet (1.68 kg DM), which also showed the highest final body weight (65.5 kg) (quadratic effect, P=0.045), total weight gain (22.6 kg) (quadratic effect, P=0.034), and daily weight gain (251.1 g) (quadratic effect, P=0.033). Higher organic matter digestibility (∼ 69.4 %) was observed (quadratic effect, P=0.016) with the lambs of FSM50 treatment (P<0.05). Replacing CSM with FSM linearly increased (P=0.024) blood antioxidant activity and decreased blood cholesterol (P=0.022), triglycerides (P=0.035) and high-density lipoprotein (P=0.034) compared to the control treatment. The highest relative percentage of net revenue was observed with the FSM50 diet (131 %) while the lowest one was observed (P=0.011) with the FSM100 diet (92.9 %). It is concluded that CSM can be replaced with FSM at 50 % in diets of growing lambs for better performance and economic efficiency.
