水虻幼虫粉对肉鸡生长性能、血液指标等的影响

Effects of Stratiomyiid Larva on the Growth Performance and Blood Indices of Broilers

选用70日龄古典型岑溪三黄鸡400羽,随机分成4组,每组100羽,对照组、处理Ⅰ、Ⅱ、Ⅲ组分别饲喂基础日粮(鱼粉2.0%日粮)、金黄指突水虻幼虫粉2.0%日粮、金黄指突水虻幼虫粉4.0%日粮、金黄指突水虻幼虫粉6.0%日粮。经过28d试验,探讨金黄指突水虻幼虫粉取代鱼粉对古典型岑溪三黄鸡生长性能、血液生化指标、肌肉氨基酸、肌肉脂肪酸等的影响。结果表明,2.0%金黄指突水虻幼虫粉组在一定程度上能促进生长,同时可促进免疫器官的生长发育,提高肌肉总氨基酸含量和肌肉饱和脂肪酸含量;2.0%金黄指突水虻幼虫粉组饲喂的血液指标中,除血清尿素氮外,其他指标均有提高。

Four hundred 70-day-old typical Cenxi three-yellow chicken were randomly divided into four groups with 100 chicken in each group. Chicken in control group, group Ⅰ,Ⅱ,Ⅲ were fed with basal diet（2.0% fishmeal ）, the diets with 2.0%,4.0%,6.0% Ptecticus aurifer larva powder respectively. The test lasted for 28 days.The effects of replacing fishmeal by P. aurifer larva powder on the growth performance,serum biochemical indices, muscle amino acid content and fatty acid content were investigated. The results showed that 2.0% P. aurifer larva powder could promote the growth, accelerate the growth and development of immune organs and enhance the contents of total amino acids and saturated fatty acids in the muscles. In the group of adding 2.0% P. aurifer larva powder, the serum physiological indices increased except for blood urea nitrogen.
