Growth, feed intake, and feed conversion of dwarf and nondwarf broiler-type chickens. 1980

H L Marks

Feed intake and feed conversion patterns of meat-type dwarf (dw) and normal contemporaries were investigated in two trials, with the Athens-Canadian randombred line used as the base population. Dwarf chickens consumed significantly less feed than normal ones the first day posthatching and in all subsequent observation periods. The deviation in body weight ratios and feed intake ratios between lines were greatest during week 1. These data indicate that the action of the dw gene is present at hatching and exerts at least part of its influence through feed intake or appetite. Feed conversion ratios (feed/gain) were lower in dwarf birds than in normal birds during week 1, whereas overall differences across 8 weeks were small. The difference in relative growth rate between genotypes was greatest during week 1; by week 4, relative growth rates were similar.
