الملخص EN

This study was conducted at poultry farm, Department of Animal production, College of Agriculture, University of Basra from 4/11/2016 to 8/12/2016 to investigate the effect of using different calcium sources on the production performance and some characteristics for tibia bones, three hundred one–day of broiler chicks were randomly distributed.

The four experimental treatments were feed on four different calcium sources diets each treatment had three replicate (25 birds/ per replicate).

Calcium source in (T1) is di Calcium phosphate as control, (T2), (T3) and (T4) as oyster shell, cow bone powder and marble dust, the Result indicated that there were a significant improvement (p<0.05) in final body weight, body weight gain, feed intake, feed conversion, production index, Length and weight and bone index, Calcium and phosphorus ratio in tibia for the treatment T2 and T3 compared with the treatment T1 andT4.

The inclusion of oyster shell, cow bone powder as calcium source in diets for broiler chickens result in beneficial effect on body weight, weight gain, feed consumption and feed conversion.

Bone parameters and production index as compared with di calcium phosphate and marble dust.
