FEEDING FREQUENCY AND DENSITY OF MICROALGAE PASTE (CHLORELLA VULGARIS) IN THE DIET OF DEKALB UNDER BATTERY CAGE SYSTEM

Poultry products are the major source of animal protein for most people throughout world and egg production is index performance commercial layer business avenue in potential increase ofincome from enterprise which focuses onegg yield, weight eggs, increasing their quality to enhance economic performance.Microalgae certainly an interesting solution, it aims its value as feed additive new applications. The experimental research was used this study evaluate laying DeKalb under two feeding regimen such density andfrequency microalgae paste Chlorella vulgaris battery type cage system. experiment conducted acompletely randomized designwith a period 30 days with 81 Dekalb same age. diet were feeds,microalgae frequencies 4 times, 3 times 2 times.Egg characteristics total number (g), length (mm), width (mm) shape (%) computed based on data frequency density. costs feeds price grown some material computation return investment. Based result, effect external eggs fed different densities production, width, weight, resulted not significantthe null hypothesis accepted. internal quality, albumen height, yolk also statistically significant. Supplementation hen can be included dietary supplement hens up 80% produce eggs.
