| Abstract | ||
| Two hundred and forty day old Cobb broiler chicks were distributed into eight groups; the experimental treatments were arranged in a factorial design (2x4) by using two levels of tartaric acid (0 and 0.30 %) and four levels of Acacia saligna leaves meal (ALM) L1, L2, L3 and L4 to be 0, 3, 6 and 9%, respectively. Results showed that supplemented broiler diets with 0.30%of tartaric acid improved digestion coefficients of CP, CF, NFE , DCP, live body weight , body gain ,feed conversion ,increased edible giblets%, digestive tract weight (%) and digestive tract length (cm) compared with the control. Increasing the level of ALM in the diet from 0 to 9% decreased the digestibility of nutrients , live body weight ,body gain and digestive tract weight (%) but , increased feed intake , edible giblets% and digestive tract length (cm) and gave inferior feed conversion. The interaction between organic acid addition and ALM level had a significant effect on improving the digestion coefficients of CP, CF, NFE , DCP, live body weight and body gain. A significant decrease in values of feed intake, feed conversion, edible giblets% and digestive tract length (cm) was seen in this respect. Also, a significant decrease in digestive tract weight (%) was detected among the fourth experimental groups fed ALM with 0.30% tartaric acid compared with the other un-treated groups. Supplemented broiler diets with 6% of ALM with 0.30%of tartaric acid improved economic efficiency % of feed and relative economic efficiency of feed as compared with the control group. It may be concluded that using 6% of Acacia leaves meal and adding 0.30% tartaric acid in the diet reflect desirable results on broilers performance. | ||
