摘要

This experiment was conducted to evaluate growth performance of five turkey genotypes, namely American Bronze (AB), Large White (LW) and their crosses F1, F2 and backcross to LW (BC1). The five genotypes were compared for body weight, feed conversion ratio and livability and were reared either under intensive (IMG) or semi-intensive (SIMG) management conditions. The assessment was carried out using performance records from 0 to 18 wk for IMG and 0 to 25 week for the SIMG. At the end of the experiment, significant differences in mean body weights (P1 and F2 crosses (P>0.05). Similarly, distinct differences in mean body weights between all genotypes under SIMG condition occurred (P0.05), however, significant differences for relative livability were recorded under SIMG conditions (P2 turkeys was worse under SIMG condition, indicating the necessity for a more careful and stringent flock management for turkeys reared under field conditions.
