Abstract
This .study was designed to investigate the effect of feeding two different sources of calcium to layer hens and its effect on performance and egg quality. The experiment was carried out through a 4 weeks period. Twenty four Bovan hens (24 weeks old) were divided randomly into two groups (12 birds/ treatment) with four replicates each in battery cages. The ration was formulated to meet the nutrient requirements for laying hens according to NRC. Two different sources of calcium (oystershell or lime stone) were used in the ration. Parameters measured were egg production, feed intake, feed conversion ratio, body weight change, egg weight, egg height, egg diameter, albumen weight, albumen height, yolk weight, shell weight and shell thickness. Results showed that the source of calcium 9oystershell or lime stone) had no significant effect on egg weight, egg height, egg diameter, albumen weight, albumen height, yolk weight, shell weight, shell thickness and shell ash. There was a significant increase (P<0.05) in egg production, feed intake, feed conversion ratio and body weight change of birds fed the ration containing lime stone. Egg production, feed intake, feed conversion ratio and body weight change were significantly reduced in birds fed the ration containing the oystershell. The results of this study suggest that inclusion of lime stone in layers ration as calcium source is more beneficial than oystershell.
