    Abstract: The present study was conducted at Alatau-Kus Farm in Kazakhstan on broiler cross Ross-308 up to 42 days of age. Three different densities of planting 19, 21 and 23/m<SUP>2</SUP> were used. Body weights at different ages, livability percentages, carcass traits and chemical analysis of blood were estimated. The result showed that for closed system the density of 21/m was more efficient than other densities.
