【摘要】：本研究为了探究蝇蛆对粪中物质转化规律和对养分的利用率,采用完全随机化设计。使用3×3的方式进行随机试验设计进行分组,将3个蝇卵量分别接种于三种不同猪粪中,共9个处理,每处理内设3个重复,每个处理互为对照,进行蝇蛆饲养试验。根据粪中干物质含量接种不同数量级蝇卵量。控制时间为蝇蛆的一个生长期,即蝇卵发育到变蛹前停止培育并收集。培养期过后对粪中残留的各营养指标进行测定,对各处理中的成蛆体内富集的营养物质进行检测并分析。研究结果如下：1.生长猪粪和育肥猪粪接种0.15g/kg蝇卵,仔猪粪接种0.1g/kg蝇卵可使粪中干物质减少量达到最大值。2.仔猪粪、生长猪粪、育肥猪粪接种0.15g/kg的蝇卵干物质达到的转化率最高。分别为8.33%,7.66%,8.65%。3.0.05g/kg和0.1g／蝇卵接种量时,仔猪粪中干物质减少量显著高于生长猪和育肥猪粪中干物质减少量(p0.05)。0.15g/kg接种量对不同种类猪粪中干物质减少量影响不显著(p0.05)。4.仔猪粪、生长猪粪和育肥猪粪分别接种0.05g//kg、0.10g/kg、0.15g/kg接种量,干物质、粗蛋白、有机物和能量均在接种量为0.15g/kg时达到最大利用率。5.0.1g/kg接种量时候,仔猪粪中能量减少量显著高于生长猪粪和育肥猪粪,在0.05g/kg和0.15g/kg蝇卵接种量时,不同粪中能量变化量不显著。6.接种相同蝇卵量时,仔猪粪中粗蛋白的减少量显著高于生长猪粪和育肥猪粪,但蝇蛆育肥猪粪中粗蛋白的利用率显著高于生长猪粪和仔猪粪。
[Abstract]:In order to investigate the transformation law of fly maggots to feces and the utilization rate of nutrients, a complete randomization design was used in this study. Three fly eggs were inoculated into three different kinds of pig dung by 3 脳 3 random experiment design. There were 9 treatments with 3 repeats in each treatment, and each treatment was used as a control to carry out the breeding experiment of fly maggots. The eggs of fly were inoculated with different orders of magnitude according to the content of dry matter in feces. The control time is a growing period of fly maggots, that is to say, the eggs of flies cease to be cultivated and collected before pupae. After the culture period, the nutrient index of the residue in the feces was determined, and the nutrients enriched in the adult maggots were detected and analyzed. The results are as follows: 1. Growth pig manure and fattening pig manure were inoculated with 0.15g/kg fly eggs, and piglet manure inoculated with 0.1g/kg fly eggs could reduce dry matter in feces to the maximum value of 0.2. The conversion rate of egg dry matter of 0.15g/kg inoculated with piglet manure, growing pig manure and fattening pig manure was the highest. When inoculated with 8.33 7.66g / kg and 3.0.05g / kg 0.1g/ fly eggs, the amount of dry matter decreased in piglets was significantly higher than that in growing pigs and fattening pigs. The inoculation amount of 0.15g / kg had no significant effect on the dry matter reduction of different kinds of pig manure. Piglet manure, growing pig manure and fattening pig manure were inoculated with 0.05g / kg / kg 0.10g / kg 0.15g / kg inoculation, dry matter, crude protein, organic matter and energy reached the maximum utilization rate of 5.0.1g / kg inoculation when inoculation amount was 0.15g/kg. The amount of energy decreased in piglet manure was significantly higher than that in growing pig manure and fattening pig manure. When inoculated with 0.05g/kg and 0.15g/kg fly eggs, the change of energy in different feces was not significant. 6. The reduction of crude protein in piglet manure was significantly higher than that in growing pig manure and fattening pig manure, but the utilization rate of crude protein in fattening pig manure was significantly higher than that in growing pig manure and piglet manure.
