[目的]研究不同比例的膨化血粉饲喂生长猪的效果,探讨在生长猪饲粮中使用膨化血粉替代鱼粉作为唯一动物蛋白源的可能性.[方法]选用75头体重15 kg的长×大×杜三元杂交猪,采用1×4+1的对比试验设计方案.[结果]相同添加量的鱼粉和膨化血粉对猪的增重及日粮蛋白质利用率均无显著影响(P﹥0.05),同样的基础日粮配方结构条件下,膨化血粉以相同添加量替代鱼粉是可行的.在2%膨化血粉添加比例的基础上,随着添加量增加,猪的增重也明显提高(P＜0.05);在平衡氨基酸的条件下,日粮蛋白利用率也随之提高.在生长猪阶段,5%的比例是膨化血粉的适宜添加量,高于此比例猪不能完全利用,同时生产性能指标不再有明显改善(P＞0.05).[结论]随膨化血粉在生长猪日粮中用量的增加,猪生产性能明显提高,最佳用量为5%;相同基础日粮配方条件下,膨化血粉代替鱼粉是可行的.

[Objective]The possibility that the expanded blood meal was instead of fishmeal as pig diet of protein source was discussed through the research on the effect of the different rate of expanded blood meal added in feed on pig growth. [Method]75 hybrid pigs(Landrace×Large white×Duroc) with the body weight of 15 kg were used as the experimental materials and the design of 1×4+1 was done for the comparison experiment. [Results]The results showed that there was no significant (P＞0.05) in the effect of same feeding amount(3%) of between the expanded blood meal and fishmeal on pig body weigh-increasing. It was completely possible that the expanded blood meal instead of the fishmeal as only animal protein resource was used in pig growth under the condition of same basic diet prescription. Based on the 2% expanded blood meal added in pig diet, the pig body weigh-increasing was significant (P＜0.05)compared with the CK with the increasing of the expanded blood meal. Under the condition of balanced amino acid application, the utilization efficiency of the protein in diet was increased. In the period of pig growth, the addition rate of 5% expanded blood meal in pig diet was optimum;and if beyond that, it was the loss of protein for pig growth. [Conclusion]The performance of pig growth was significantly improved with the increment of the expanded blood meal in pig diet and 5% of expanded blood meal was the best adding amount in pig diet and it was possible for the expanded blood meal to be instead of the fishmeal under the condition of same basic diet prescription.
