This experiment was conducted on 60 unsexed one day old Ross broiler chicks to study the effect of four different feeding programs on productive characteristics during 0-8 weeks . The birds were raised in individual cages and distributed in to 4 treatments with 15 birds as replicates . Three rations...

| Summary: | This experiment was conducted on 60 unsexed one day old Ross broiler chicks to study the effect of four different feeding programs on productive characteristics during 0-8 weeks . The birds were raised in individual cages and distributed in to 4 treatments with 15 birds as replicates . Three rations were formulated including starter, grower and finisher ration which included 2800, 2900, and 3047 Kcal/Kg ME and 22 , 20 ,19.19(%) CP respectively. T1 included feeding grower ration from 0 – 8 weeks, T2 and T3 included feeding starter- grower- finisher rations for 3-3-2and 2-4-2 weeks respectively , while T4 included feeding starter and finisher rations for 0-4, 5-8weeks respectively. Statistical analysis showed that T1 had significant increase(P≤ 0.05) in body weight at 2,4,6,8 weeks , weight gain, growth rate, feed consumption, feed , protein and energy conversion ratio, during 0-4 weeks. Differences were not significant during 5-8 weeks in most traits , T3 showed significant decrease comparing to T1 in feed, protein, and energy conversion ratio during 5-8 weeks. Treatments had no significant effect on dressing percentage , percentage of carcass parts and edible giblets , and first treatment had best economic efficiency. |
