This study was carried out to investigate the growing and production parameters of Brown Nick, Isa Brown and Tetra SL hybrids in the same rearing conditions. 1600 chicks from each genotype were used and Ihey reared on litter system till 16th week. After 16 week age they are moved battery cages where for each pullet has 45 cm2 field, and their production were examined till 72 week.
The weight of Brown Nick, Isa Brown and Tetra SL genotypes in 18 weeks of age were found 1481, 1517 and 1514 g, respectively. The mortality rate in growing period of above groups were found 2.81, 1.75 and 1.50% (P<0.05), and mortality rate at production period were found 23.92, 27.82 and 19.44% (P<0.05), respectively.
Total feed consumption were found 6857, 6826 and 6685 g at 0-18 week and feed consumption for producing per egg was 135.5, 136.5 and 145.7 g, respectively. 50% egg production age of above groups were found 154, 148 and 150 day and egg production for per hen per housed were found 281, 258 and 257 (P<0.05) and average egg weight were found 58.55, 60.59 and 59.84 g, respectively.
It was concluded that the mortality rate and feed consumption of Tetra SL at rearing period was better than other genotypes. Egg production per hen per housed and feed consumption for producing per egg of Brown Nick was better than other genotypes.
