摘　　要：饲料型四倍体刺槐,具有速生、叶大、条粗、枝密、无刺等特点,非常适宜作为优质饲料。采用四倍体刺槐与苜蓿作对比,试制了5种饲料配方,在伊拉品种肉兔上进行了对比试验。结果表明,以纯四倍体刺槐完全替代苜蓿饲喂肉兔后,净肉率有所提高,生产成本和屠宰率未有显著变化,但肉免的净增重和饲料消化率则出现明显下降,料肉比增大,总体应用效果不佳;相比之下,以四倍体刺槐替代一半苜蓿后,肉免净增重和净肉率均得到显著提高,料肉比明显下降,生产成果显著降低。研究结果表明,以饲料型四倍体刺槐部分取代饲料之王苜蓿是完全可行的,以20%刺槐粉+20%苜蓿粉相配合的应用效果最好。The feed type tetraploid Robinia pseudoacacia has the characteristics of fast growth,large leaves,thick strips,dense branches and no thorns,so it is very suitable for high-quality feed.Five kinds of feed formulas were developed by comparing Robinia pseudoacacia with Medicago sativa,and the comparative test was carried out on IRA meat rabbit.The results showed that the digestibility,feed to meat ratio,slaughter rate and lean meat ratio of pure tetraploid Robinia pseudoacacia were 57.3%,3.5%,58.9%and 67.8%respectively.Compared with the control(alfalfa),although the feed to meat ratio was increased,the cost of pure tetraploid Robinia pseudoacacia was slightly lower than that of alfalfa,The best combination was 20%tetraploid Robinia pseudoacacia powder+20%alfalfa powder.
