不同比例的玉米豆粕日粮饲喂生长獭兔的效果研究

Study on feed effects of different proportion of corn-soybean meal diet in growing rex rabbit

旨在研究不同比例的玉米豆粕日粮对生长獭兔的试验效果,以筛选最佳饲料配方。选择45日龄健康的生长獭兔100只,随机分成5组。处理Ⅰ、Ⅱ、Ⅲ、Ⅳ组为试验组,分别饲喂单玉米型日粮、单豆粕型日粮、双兼型日粮、双无型日粮;对照组,饲喂常规玉米-豆粕型日粮。试验期为56 d。结果表明,与对照组相比,各试验组生长獭兔的末重、日增重、料重比差异均不显著(P>0.05);各试验组獭兔的采食量均较对照组有所提高,以Ⅳ组最高,与对照组相比差异显著(P<0.05);各试验组日粮均降低了獭兔的腹泻率和死亡率;Ⅰ、Ⅱ、Ⅲ组各营养物质的消化率与对照组相比,差异均不显著(P>0.05);各试验组生长獭兔被毛品质未产生不良影响,且饲料成本显著降低。由此可见,适当降低玉米和豆粕使用量,合理搭配日粮在技术上是可行的,可获得较好的饲喂效果,显著提高经济效益。

The experiment was conolucted to study the effects of different proportion of corn-soybean meal diet on produetion performance in rex rabbit.One hundred healthy weaning growing rex rabbits at age of 45 days were divided into five groups randomly.Treatment group Ⅰ , Ⅱ , Ⅲ, 1V were fed with single corn type diet,single soybean meal type diet,both corn and soybean meal type diet,no corn and soybean meal type diet. Group V was the control group and fed with corn- soybean meal type diet.The experiment time was 56 days.The experiment results showed that： compared with the control group final weight,daily weight gain,daily feed gain and feed gain ratio of all treatment groups had no obvious effect （P 〉 0.05 ） ;feed intake of group IV was significantly higher than that of control group （P 〈 0.05 ）, the diarrhea rate and mortality of growing rex rabbits were decreased.The nutrient digestibility of group Ⅰ , Ⅱ , Ⅲ had no siguificant effects.The hair quality of all treatment groups had no siguificant effects and feed cost was siguificautly decrased.The results indicated that,at present,it was feasible to derease the usage of corn-soybean and design the feed formula reasonably,which could obtain the optimum feeding effect and improve economic benefits significantly.
