Abstract
: A total of 150 unsexed one-day old Arbor acers broiler chicks were randomly divided into five experimental groups. Each group consisted of 30 chicks distributed among 3 replicates with 10 chicks per replicate. The control group (G1) received a basal diet (yellow corn-soybean meal diet). Groups 2 and 3 received the basal diet after replacing 25% of yellow corn with whole de-pitted low grade dates meal (WDDM), either without (G2) or with (G3) multienzyme mixture (xylanase, β-glucanase and cellulase). Moreover, Groups 4 and 5 received the basal diet after replacing 50% of yellow corn with WDDM either without (G4) or with (G5) multienzyme mixture. The experiment prolonged for 6 weeks and the birds received starter diet from 0 to 3 weeks of age and grower diet from 4 to 6 weeks of age.
The results revealed that replacing 25% of yellow corn with WDDM plus enzyme mixture supplementation (G3) significantly increased body weight and body weight gain compared to G2, G4 and G5. However, broilers of G2 exhibited higher body weight than those fed WDDM in place of 50% of yellow corn without enzymes supplementation (G4), and surpassed those fed WDDM in place of 50% of yellow corn with enzymes (G5). Despite of the slight decrease of BW of G2, G3, G4 and G5 as compared with the control group (G1) (92.83, 98.49. 85.58 and 90.93 vs. 100%, respectively), however, because of the high cost of yellow corn and low cost of WDDM, the relative economic efficiency compared to the control group was better for all groups received WDDM without enzymes (105% and 109% for G2 and G4, resp.) or with enzymes (115% and 113% for G3 and G5, resp.). The diet contained WDDM instead of 25% of yellow corn fortified with enzymes (G3) also improved feed conversion ratio and digestibility of dry matter, ether extract, and crude fiber. Nevertheless, there were no significant differences in crude protein digestibility or feed intake among the experimental groups. However, replacing 25% or 50 %of corn with WDDM plus enzymes increased cholesterol and LDL without affecting triglycerides or HDL levels. Nevertheless, there were no significant effects on liver and kidney functions, antioxidant capacity, or hematological parameters. In conclusion, based on the relative economic efficiency and on the local availability of WDDM compared to imported yellow corn, replacing from 25% up to 50% yellow corn with whole low grade de-pitted dates meal plus enzymes mixture may be recommended for practical application in broiler diets.
