单一饲料及其搭配养殖中华真地鳖效果研究

采用单一饲料的玉米、麦麸、米糠以及由它们配制成的粗蛋白质含量分别为13.5%、15.1%和16.5%的3种配合饲料共6种饲料搭配投喂模式,研究其对养殖中华真地鳖效果的影响。结果表明,中华真地鳖分别摄食3种配合饲料后的生长速度均比3种单一饲料的要快,其中以投喂粗蛋白质含量为15.1%组的生长速度最快;分别投喂3种单一饲料的中华真地鳖,除玉米组外的其余2个组的饲料成本均明显低于3种配合饲料各组,并且以投喂麦麸组所取得的经济效益最显著。

Study on Effects of Breeding Eupolyphaga sinensis Walker Using Single Forage and Their Mixture

6 kind forages were used to feed Eupolyphaga sinensis Walker. They were single corn, wheat bran, rice bran and their mixtures. Each mixture contains 13.5%, 15.1% and 16.5% crude protein respectively. The results showed: (1)Eupolyphaga sinensis Walker fed with mixed forage grown faster than that fed with single forage, the best result is the mixed forage containing 15.1% crude protein. (2)Among above 3 single forages, wheat bran and rice bran cost distinctly lower than the 3 kind mixed forages, and wheat bran is the cheapest.
