Abstract

The present study was conducted to study the response of using some suggested feeding regimens on broilers after the finishing period. Two-hundred and fifty day-old Arbor Acres chicks were fed on commer‌cial starter/grower and finisher diets to 7 weeks of age. On the start of 8th week of age, chicks were randomly divided into 18 groups (10 chicks/group). Chicks were fed according to six feeding regimens (treatments): T1, finisher diet (18% CP). 72, T3 and T4 were 10, 20 or 30% restriction of feeding 18% diet (T1), respectively. T5 was Skip-a‌day feeding every two days ad lib, whereas, TO was 14% protein diet. Growth performance and carcass characteristics were measured at the end of the experiment. Results obtained were as follows: Insignificant differences were found between chick groups fed on the fin‌isher diet (T1) and low protein diet (T6) for body weight gain (BWG) and feed efficiency (FE). Chick groups fed on the restriction regimens (T2, T3 and T4) resulted in gradient reduction in BWG, 12.56, 20.63 and 34.92% relative to T1, re‌spectively. A skip-a-day group (T5) decreased in the final body weight {FBW), BWG and FE 6.74. 39.62 and 15.44%, respectively as compared to Ti. There were a significant decrease in abdominal fat weight (AFW) 27.8, 44.9, 47.1, 54.2 and 55.5% for T2, T3, T4, T5 and 76, respectively, as compared to (T1). The economical evaluation showed 22.08% reduction in feed cost/kg. gain for the low protein diet (T6) relative to the finisher diet (T1). How‌ever, the other feeding regimens caused an increase in feed cost/Kg. gain 2.86, 0.91, 7.48 and 18.01% for T2, T3, T4 and T5, respectively as compared to (T1).
