Effect of Dietary Growth Promoter Supplementations on the Serum Biochemistry and Morphometric Characteristics of Tibia Bone in Broiler Chicken

Bone mineralization is considered an essential source of minerals for metabolic needs that provide strength and hardness to the bone tissues in birds its development can be enhanced by use dietary supplements. The present study was executed evaluate influence prebiotic, probiotic antibiotic on morphometric aspects tibia broilers. One-hundred sixty-one-day-old broiler chick were divided randomly into four groups (n=40) with 4 replicates (n=10 each replicate). Group-I fed only corn based basal diet served as controlled group. Group-II supplement (Zinc bacitracin 0.04%), Group-III (lactobacillus 0.1%) & Group-IV prebiotic (mannan oligosaccharide 0.1%). On 35th day, two selected from replicate slaughtered record parameters both right left bones bird. findings showed length, weight, thickness lateral medial wall, tibiotarsal index ash percentage supplemented have had significant (p<0.05) difference when compared weight/length significantly higher than control Medullary canal diameter all lower No (p>0.05) robusticity diaphysis observed among various groups. A low level Alkaline Phosphatase while Calcium Phosphorus recorded In conclusion, growth promoter exhibit some underline mechanisms form enhancement quality, density characteristics chicks common antibiotics.
