不同单一饲料及其搭配对养殖中华真地鳖效果的对比研究

Study on effects contrast of breeding Eupolyphaga sinensis Walker using different single forage and their mixture

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%的三种配合饲料共六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:(1)中华真地鳖分别摄食三种配合饲料后的生长速度均比三种单一饲料的要快,其中以投喂粗蛋白质含量为15.1%组的生长速度最快。(2)分别投喂三种单一饲料的中华真地鳖,除玉米组外的其余两组,其饲料成本均明显低于三种配合饲料各组,并且以投喂麦麸组所取得的经济效益最显著。

6 kind forages were used to feed Eupolyphaga sinensis Walker, which were single corn, wheat bran, rice bran and their 3 kind mixtures. Each mixture contains 13.5%, 15.1% and 16.5% crude protein respectively. The results showed： （1） Eupolyphaga sinensis fed with mixed forage grew faster than that fed with single forage, in which it grew fastest fed with 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, in which fed with wheat bran alone received the most remarkable economic benefit.
