This study was conducted to examine the effect of 4 different quality criteria (chick weight, toe length, shank length and chick length) on live weight, feed consumption, feed conversion ratio and mortality in broiler chicks at the end of the fattening period. A total of 192 male broiler chicks were used in the experiment, and two separate groups were formed for each quality criterion. In 1 day-old chicks, a heavy group and a light group (≥47.7 g and <47.7 g) were created for chick weight; and a tall group and a short group were created for each of the toe length (≥2.01 cm and <2.01 cm), shank length (≥2.9 cm and <2.9 cm) and chick length (≥18.3 cm and <18.3 cm) criteria. At the end of the six-week fattening period, the live weight was significantly higher in the heavy group compared to the light group; in the short toe group compared to the tall toe group; and in the short chick length group compared to the tall chick length group (P<0.01 and P<0.01). In terms of feed consumption, more feed was consumed in the heavy group compared to the light group; in the short shank group compared to the tall shank group; and in the short chick length group compared to the tall chick length group (P<0.01). The feed conversion ratios were influenced by the quality criteria, and the feed efficiency was better in the heavy group compared to the light group; in the short toe group compared to the tall toe group; and in the short chick length group compared to the tall chick length group. The mortality of the experimental groups showed significant differences in the groups other than the shank length group (P<0.05).
