Abstract

This study investigated the effects of dietary housefly larvae and frass (HFLF), with or without a multi-component supplement (Rayabold), on the performance, egg quality, and blood biochemical parameters of Lohmann LSL-Lite laying hens. A total of 192 hens, aged 56 weeks, were assigned to a 10-week feeding trial using a 4 × 2 factorial design with four HFLF inclusion levels (0 %, 5 %, 10 %, and 15 %) and two Rayabold levels (0 % and 0.05 %). A significant interaction was observed for feed intake (FI) (P = 0.0001), with hens fed 10 % and 15 % HFLF consuming less feed than those on the control or 5 % diets. Rayabold further reduced FI at higher HFLF levels. Egg production (EP) improved significantly with 10 % and 15 % HFLF (P = 0.024), while egg weight (EW) peaked at 5 % HFLF (P = 0.003) and was further enhanced by Rayabold (P = 0.008). Both HFLF and Rayabold improved feed conversion ratio (FCR), protein efficiency ratio (PER), and energy efficiency ratio (EER) (P = 0.0001), with the 15 % HFLF diet yielding the most favorable values. In terms of egg quality, higher HFLF levels (10 % and 15 %) reduced eggshell thickness (P = 0.002), while Rayabold increased it (P = 0.0007). Haugh unit values were elevated in the 10 % and 15 % HFLF groups (P = 0.043). Regarding blood parameters, 10 % HFLF lowered glucose (P = 0.0007), and both 10 % and 15 % HFLF increased cholesterol (P = 0.001), with Rayabold further elevating it (P = 0.030). Triglycerides were reduced by both 10 % HFLF and Rayabold (P = 0.050 and P = 0.0001, respectively). HFLF decreased AST (P = 0.0001) and increased albumin (P = 0.006). Complex interactions were noted for ALT and ALP (P = 0.0003 and P = 0.0001), with Rayabold mitigating the ALT increase seen at 5 % HFLF, and all treatments significantly lowering ALP compared to control. These findings support HFLF, particularly at 10-15 %, as a promising poultry feed ingredient for improving productivity and modulating physiological responses.

摘要

本研究调查了日粮中添加家蝇幼虫和虫粪（HFLF），无论有无多成分补充剂（Rayabold），对罗曼LSL-Lite蛋鸡生产性能、蛋品质和血液生化参数的影响。选取192只56周龄的母鸡，采用4×2析因设计进行为期10周的饲养试验，HFLF添加水平有4个（0%、5%、10%和15%），Rayabold添加水平有2个（0%和0.05%）。观察到采食量（FI）存在显著交互作用（P = 0.0001），饲喂10%和15% HFLF的母鸡采食量低于对照组或5%日粮组。在较高HFLF水平下，Rayabold进一步降低了采食量。添加10%和15% HFLF时，产蛋量（EP）显著提高（P = 0.024），而蛋重（EW）在HFLF添加量为5%时达到峰值（P = 0.003），Rayabold使其进一步提高（P = 0.008）。HFLF和Rayabold均提高了饲料转化率（FCR）、蛋白质效率比（PER）和能量效率比（EER）（P = 0.0001），15% HFLF日粮组的值最为理想。在蛋品质方面，较高的HFLF水平（10%和15%）降低了蛋壳厚度（P = 0.002），而Rayabold增加了蛋壳厚度（P = 0.0007）。10%和15% HFLF组的哈氏单位值升高（P = 0.043）。关于血液参数，10% HFLF降低了血糖（P = 0.0007），10%和15% HFLF均增加了胆固醇（P = 0.001），Rayabold使其进一步升高（P = 0.030）。10% HFLF和Rayabold均降低了甘油三酯（分别为P = 0.050和P = 0.0001）。HFLF降低了谷草转氨酶（AST）（P = 0.0001）并增加了白蛋白（P = 0.006）。谷丙转氨酶（ALT）和碱性磷酸酶（ALP）存在复杂的交互作用（P = 0.0003和P = 0.0001），Rayabold减轻了5% HFLF时ALT的升高，与对照组相比，所有处理均显著降低了ALP。这些研究结果支持HFLF，尤其是10%-15%的添加量，作为一种有前景的家禽饲料成分，可提高生产性能并调节生理反应。
