摘要: Nutrient apparent digestibility coefficients (ADCs) of pet food grade poultry by-product meal (PBM) were determined for black tiger prawn, Penaeus monodon and Pacific white shrimp, Litopenaeus vannamei by the indirect method (reference diet and test diet at 7:3 ratio). Subsequently, an 8-week growth trial was conducted to evaluate the effects of substitution of fishmeal (FM) with PBM in diets of P. monodon (initial weight similar to=similar to 0.21 +/- 0.01g). In the growth trial, six isonitrogenous and isoenergetic diets PBM0, PBM25, PBM50, PBM75, PBM100 and PBMA100, containing a gradient of PBM 0, 88.7, 177.4, 266, 354.7 and 354gkg-1 to replace 0, 92.5, 185, 277.5, 370 and 370gkg-1 FM were fed to four replicate groups respectively. The diet PBMA100 was supplemented with DL-Met to be similar to PBM0. The results showed that both P. monodon and L. vannamei had relatively high ADC of crude protein (77.6% and 84.2% respectively) and gross energy (72.8% and 84.0% respectively) for PBM. Litopenaeus vannamei showed significantly higher digestion ability for PBM than P. monodon (P<0.05). In growth trial, no significant difference in growth performance was observed among shrimp fed the experimental diets. DL-Met supplementation did not improve the growth of P. monodon. PBM is a suitable protein ingredient for P. monodon feeds and can be used up to 354.7 g kg-1 to totally replaced FM.
