Twenty-four Holstein steers were used in a 5-d digestion trial to evaluate chickpeas as a substitute for corn and soybean meal. Total mixed diets contained (dry basis) 51% concentrate mix, 33% corn silage, and 16% alfalfa hay. Concentrate mixes contained 0, 50, and 100% chickpeas in place of corn and soybean meal. Ad libitum intakes of DM were not different between diets. Digestibilities of DM, NDF, ADF, hemicellulose, cellulose, lignin, and gross energy were not different among diets. Digestibilities of protein, fat, and ash were greater for steers fed 100% chickpeas than 0% chickpeas. Fecal N was lower and absorbed N was higher for steers fed 100% chickpeas. Ruminal acetate and acetate:propionate ratio were lower and ruminal propionate was higher for all steers fed diets containing chickpeas. Ruminal ammonia and pH were similar for all treatments.
选用24头荷斯坦公牛进行了一项为期5天的消化试验，以评估鹰嘴豆作为玉米和豆粕替代品的效果。全混合日粮（干基）包含51%的精料混合料、33%的玉米青贮料和16%的苜蓿干草。精料混合料中用0%、50%和100%的鹰嘴豆替代玉米和豆粕。各日粮之间干物质随意采食量没有差异。日粮之间干物质、中性洗涤纤维、酸性洗涤纤维、半纤维素、纤维素、木质素和总能的消化率没有差异。饲喂100%鹰嘴豆的公牛对蛋白质、脂肪和灰分的消化率高于饲喂0%鹰嘴豆的公牛。饲喂100%鹰嘴豆的公牛粪便氮含量较低，吸收氮含量较高。所有饲喂含鹰嘴豆日粮的公牛瘤胃乙酸和乙酸:丙酸比值较低，瘤胃丙酸含量较高。所有处理的瘤胃氨和pH值相似。
