Replacement of conventional feedstuffs with cheap non-conventional ingredients may improve livestock performance and the quality of their products, particularly milk. The study considered the effects of Moringa oleifera (MO) foliage in replacement of berseem clover (BC) on feed utilisation and lactational performance in Nubian goats. A total of 16 lactating Nubian does, weighing 36.2±0.8 kg, were randomly assigned to four experimental treatments containing 0, 125, 250 and 375 g of MO per kg diet to replace 0 (M0), 25 (M25), 50 (M50) and 75% (M75) of BC (on dry matter (DM) basis) in a quadruplicated 4×4 Latin square design. The MO diets increased (P<0.01) feed intake and nutrient digestibility. Feeding MO diets improved (P<0.01) ruminal volatile fatty acids, acetate and propionate but reduced (P<0.01) valerate and iso-butyrate. Moringa diets increased (P<0.01) serum total protein, albumin and glucose but decreased (P<0.05) cholesterol and triglycerides. Milk yield and energy corrected milk, and milk total solids, fat and energy content were increased (P<0.01) in MO diets. Yields of milk components and energy were greater (P<0.05) for MO diets than for control diet. Milk total saturated fatty acids and athrogenicity index were lower (P<0.01), and unsaturated fatty acids, conjugated fatty acids and UFA/SFA ratio higher (P<0.05) for MO diets. It is concluded that feeding MO to replace 75% DM of BC improved feed utilisation, ruminal fermentation, and milk yield and quality in lactating Nubian goats.
用廉价的非常规成分替代常规饲料可以提高牲畜的生产性能和产品质量，特别是牛奶。本研究考虑了用辣木（Moringa oleifera，MO）叶替代百喜草（Berseem clover，BC）对努比亚奶山羊的饲料利用和泌乳性能的影响。共有 16 头泌乳期的努比亚母羊，体重 36.2±0.8kg，随机分为四个试验处理组，每组 4 个重复，每个重复 1 只羊，分别饲喂含 MO 0、125、250 和 375g/kg 日粮，以替代基础日粮中 0（M0）、25（M25）、50（M50）和 75%（M75）的 BC（干物质基础）。MO 日粮增加了（P<0.01）饲料采食量和养分消化率。饲喂 MO 日粮提高了（P<0.01）瘤胃挥发性脂肪酸、乙酸和丙酸，但降低了（P<0.01）戊酸和异丁酸。MO 日粮增加了（P<0.01）血清总蛋白、白蛋白和葡萄糖，但降低了（P<0.05）胆固醇和甘油三酯。MO 日粮增加了（P<0.01）产奶量、能量校正奶、乳总固形物、脂肪和能量含量。MO 日粮的乳成分和能量产量均高于（P<0.05）对照组。MO 日粮的乳总饱和脂肪酸和athrogenicity 指数降低（P<0.01），不饱和脂肪酸、共轭脂肪酸和 UFA/SFA 比例升高（P<0.05）。综上所述，用 MO 替代 75%的 BC DM 可提高泌乳努比亚奶山羊的饲料利用效率、瘤胃发酵、产奶量和乳品质。
