RESUMO
ABSTRACT The aim of present study was to evaluate the effect of feeding vegetable waste (VW) to broilers on their growth performance, serum chemistry, immune status, meat mineral content and lipid oxidation status. For this purpose, 100 one-day-old chicks (Cobb 500) were acquired from a commercial hatchery and allocated according to a completely randomized design into five dietary treatments with four replicates of five birds each. The dietary treatments included: T1 ( 100 % c o m m e r c i a l f e e d ( C F ) + 0 % V W), T2 ( 75 % C F + 25 % V W), T3 ( 50 % C F + 50 % V W), T4 ( 25 % C F + 75 % V W) and T5 ( 0 % C F + 100 % V W). Experimental birds were subjected to dietary treatments from 5 to 7 weeks of age. At the end of week 7 (49 days), eight birds with uniform average body weight were selected per treatment (2birds/replicate), kept off-feed for 4 h and then manually slaughtered according to the Halal method to collect data for serum chemistry, meat minerals and lipid oxidation status. The results indicated better meat lipid oxidation status (p≤0.05) and lower meat mineral content (p≤0.05) when birds fed VW at 25, 50, 75, and 100% of the diets compared with 100% commercial feed. On the other hand, blood chemistry and antibody response parameters did not respond (p>0.05) to dietary intervention. In conclusion, dietary inclusion of vegetable waste had positive influence on meat quality in terms of meat lipid oxidation and meat mineral content, and may be replace up to 75% of commercial broiler feeds with beneficial effects.
