1 Dr., Vet. Hekim., Lalahan Hayvancılık Araştırma Enstitüsü Müdürlüğü, ANKARA Viewed : 769 - Downloaded : 469 Live weights, feed consumption, feed convertion, slaughter and carcass characterictics of four different genotypes were investigated in Lalahan Livestock Researche institute. İn the experiment 416 chicks were used.

The animals were fed with 22 CP and 3000 Kcal/Kg M.E. ration on days 0 - 21, and 20 CP and 3150 Kcal/Kg M.E. ration on days 22 -45.

At the end of the experiment average live weights of the groups were 1960, 1973, 2059 and 1919 g. respectively. Total feed consumption and feed convertion in the groups were determined as 3865, 3668, 4024, 3909 g. and 1.97, 1.85, 1.95 and 2.01 respectively. Carcass weights of groups were found 1414, 1 415, 1449 and 1429 g. respectively.

The observed, values in group of Erbro were estimated lower than the other genotypes. Keywords : Broiler, carcass, production values
