EFFECT OF USING SOME NATURAL FEED ADDITIVES TO SUBSTITUTE ANTIBIOTIC GROWTH PROMOTERS ON PERFORMANCE AND BLOOD PARAMETERS OF BROILERS
This investigation aimed to evaluate the biostrong, probiotic or pungent substance as natural feed additives instead of antibiotics (zinc bacteriacin) on growth performance, carcass characteristics, bone measurements, some blood metabolites and economic efficiency of broiler chicks. One hundred and fifty unsexed one day old age Hubbard chicks were weighed and randomly allocated for four dietary treatment groups. The 1st group was fed the basal diets without supplementation (control), while the 2nd, (T1) the 3rd (T2), the 4th (T3), and 5th (T4) groups were fed the basal diets supplemented with biostrong, probiotic, pungent substance and zinc bacteriacin at the level of 150g, 1000g, 500g and 500g/ton, respectively. Diets and water were provided ad lib. throughout the experimental period (1-32 days of age). The results indicated that:- 1- Body weight gain, feed intake and feed conversion for the broiler chicks fed basal diets supplemented with pungent substance (T3) were significantly differences than those fed control diets at 18 days of age. However at 32 days of age there were insignificant differences among treatments in body weight gain, but numerically pungent treatment (T3) represented the highest body weight gain and significant lowest feed intake and significant improved feed conversion. 2- Total edible parts were significantly higher for the treatments received probiotic (T2) or pungent substance (T3) than those fed on control diets. 3- Bone measurements (wet tibia weight, Tibia length, Tibia width and tibia seedor Index) showed that insignificant figures when broiler chicks fed different dietary treatments. 4- Blood parameters showed insignificant figures in most parameters. However uric acid and ALP activity have significant difference (P0.05) for dietary treatments.
