Abstract
- The goal of this study was to evaluate the effects of Tenebrio molitor (TM) larvae meal on the growth performance, serum biochemical parameters and caecal metabolome of broiler chickens. A total of 600 1-d-old male Liangfenghua broilers were randomly assigned to five equal groups with 5 replicates and 24 birds in each replicate. The dietary treatments were as follows: the control group (TM0 group) was fed a basal diet, and the experimental groups were fed experimental diets in which 3% (TM3 group), 5% (TM5 group), 7% (TM7 group) and 9% (TM9 group) TM larvae meal included in the basal diet, respectively. The feeding period was 70 d. The results showed that body weight (BW) and average daily gain (ADG) significantly increased (p 1.5) and the relative contents of 27 metabolites like prostaglandin F2α, glucocorticoids and prostaglandin E2 were significantly down-regulated (FC < 0.667) in the TM3 group. The main altered pathways were clustered into arachidonic acid metabolism, primary bile acid metabolism and propionic acid metabolism. In conclusion, the results indicated that supplementation of 3% TM larvae meal can improve growth performance, reduce the activity of serum AST and the content of TG, and regulation of the pathways of lipid, amino acid, and sugar metabolism in the caecum of broilers by improving nutrient digestion and absorption.
