摘要

Effects of total replacement of soybean meal (SBM) with defatted black soldier fly larvae meal (BSFLM) on egg production and quality, organ weight, and apparent retention (AR) of components were investigated in Shaver White hens from 28 to 43 wk of age. A total of 108 birds, (6 birds/cage) were assigned to three diets (6 replicates/diet). Diets were control corn–SBM diet and two additional diets made with the addition of either 10 or 15% BSFLM. Diets met or exceeded breeder specifications, contained TiO2 as an indigestible marker, and were prepared in pellet form. Birds had free access to feed and water throughout the experiment. Hen-day egg production (HDEP) was monitored daily. Feed intake (FI) and body weight (BW) were monitored in 4-wk intervals. All eggs laid on the sixth day of wks 31, 35, 39, and 43 were used for egg weight (EW), Haugh units (HU), yolk color (YC), shell breaking strength (SBS), and shell thickness (ST). Excreta samples were collected for 3 consecutive days on wk 33 for AR and two birds/cage were necropsied at the end. There were no (P > 0.05) diet effects on HDEP, FI, and HU. Inclusion of BSFLM linearly decreased (P < 0.05) egg mass and feed conversion ratio (FCR) and quadratically increased (P < 0.05) BW. There was no (P > 0.05) interaction between diet and sampling time point on egg quality parameters. Inclusion of BSFLM increased SBF and YC linearly (P < 0.05) and ST quadratically (P = 0.028). Inclusion of BSFLM quadratically (P ≤ 0.01) reduced empty ceca weight and increased liver weight and had no effect (P > 0.05) on gizzard, small intestine, and pancreas weights. Feeding BSFLM linearly (P = 0.001) and quadratically (P = 0.007) increased apparent metabolizable energy (AME). Data showed that defatted BSFLM resulted in deeper orange yolks and improved eggshell quality; however, unfavorable FCR linked to lighter eggs as well as heavier birds and liver warrants further investigations.
