Effect of different stocking densities and flock size on welfare and behavior of white leghorn layers in conventional California cages

The present investigation was planned to study the welfare and behavior performance of laying hens at two different stocking densities and flock size in conventional California cages. A total of 180 commercial White Leghorn (strain BV 300) layers were divided into four groups with six replicates and reared under standard managemental practices. Interaction effect of two best stocking density (548 and 645cm²/b) and flock size (06 and 09 birds) in conventional cages was conducted along with comparison of welfare and behavior of commercial laying hens in conventional California cages. Interaction effect of stocking density and flock size resulted in non-significant effect on all of the welfare parameters and total state and event behavioral parameters except significantly better sleeping, drinking and least feather pecking was observed in 548cm²/b x 6B. Therefore, it could be concluded that rearing of commercial layer in conventional California cages is best suited for stocking density of 548cm²/b or 85 sq. inch/b with flock size of 6 birds.
