摘  要:将24头荷斯坦牛随机分成两组进行了为期30天的饲养试验,对照组饲喂食24%豆粕的精料,试验组饲喂含12%干豆腐渣(DTP)+12%豆粕的精料。结果表明,DTP组与豆粕组在泌乳量、乳脂率、精料消耗量以及泌乳量/精料消耗量方面均无显著差异(P>0.05);DTP组的精料成本显著低于豆粕组(8.32:9.27元/头·日,P<0.05)。经济效益分析表明,用DTP替代豆粕可降低生产成本。In the contrast trail, which lasted 30 days, 24 Holstein cows were randomly divided into two groups; the control group, in which Holstein cows were fed the concentrate contented 24% soybean meal (SM), and the trail group, in which Holstein cows were fed the concentrate contented 12% SM and 12% dried tofu pulp (DTP). The results were listed as below: There were no significant differences of milk yield, milk fat percentage, concentrate consumption, and the rate of milk yield:concentrate consumption between two groups (p>0.05). The concentrate cost of the DTP group was significantly inferior to that of the SM group (p<0.05). The analysis of economic benefits showed that the production cost would reduced 236619 yuan (900 lactating Holstein cows) every year by substituting DTP for SM.
