Abstract

An experiment was carried out to evaluate the effects of calcium and vitamin D levels on performance and egg shell quality of commercial laying hens. Two hundred-forty pullets at 16 weeks of age were allotted in completely randomized experimental design, 3 x 2 factorial arrangement (3 calcium levels – 1.3; 1.8 and 2.3% and 2 vitamin D levels – 1,200 and 2,400 IU/kg of diet), with five replications of eight birds each. The performance of the parameters was not influenced by dietary treatments. Egg specific gravity was improved by the increased level of vitamin D in the diet. Result shows that 1.3% calcium and 1,200 IU/kg of vitamin D are enough to achieve the best performance of the Hisex Brown laying hens
