an experiment was conducted to evaluate the effect of feed restriction (fr) and meal feeding (mf) on performance, carcass characteristics and related parameters to ascites in ross 308 male broiler chickens. five dietary treatments were 1) the control (ad libo. feeding), 2 )feed restriction from 7 to 14 days (fr14), 3) feed restriction from 7 to 21 days (fr21), 4) meal feeding from 7 to 14 days ...

This study was carried out to evaluate the duration of time of feeding starter and finisher diets on live performance and carcass characteristics of female broilers. Starter diet was fed to 14 or 21 days of age. Finisher diet was fed beginning at 35 or 42 days up to 49 days of age. The results indicated that reduction of duration of feeding starter diet reduced weight gain (P<0.0071) and impair...
