Two birds (28 d) from each replicate were selected randomly and blood was collected to study the blood biochemistry and carcass traits.
Results & Conclusion:As the result revealed, feed additives did not affect body weight throughout the experimental period significantly. Numerically, the higher and the lower daily body weight gain were observed in chicks with diets containing probiotics and antibiotics respectively. Improved feed efficiency belonged to diets supplemented with probiotics. Aleo Vera jelly powder (AVJP) improved feed efficiency as compared to control groups. The higher and the lower feed intake showed in diets supplemented with AVJP 0.2% and diets containing probiotics 0.1% respectively. Non- significant higher carcass and live body weight ratio referred to diets containing AVJP 0.1% and control groups respectively. Significantly higher and the lower abdominal fat percentage were observed in chicks consumed AVJP 0.1% and diets included with antibiotics (p<0.05). Aleo vera jelly powder significantly improved immune responses through increasing weight of burs gland (p<0.05). Numerically AVJP increased number of WBC and increased significantly influenza and Newcastle disease titrations (p<0.05). The higher and the lower blood cholesterol were related to the diets supplemented with probiotics nd 0.1% AVJP respectively (p<0.05).
