摘要

A study was carried out to evaluate growth performance and carcass characteristics of broiler birds fed with varying level of choline inclusion in their diets;T1(control),T2(10g/10kg)and T3(20g/10kg).A total of 225 marshall broiler chicks were randomly divided into three(3)treatment group of 75 birds each.Each group was divided into five(5)replicates of fifteen(15)birds each laid in a completely randomized design.Feed and water was supplied ad-libitum and the experiment lasted for 49 days.The total feed intake(1316.75-14442.18)(24437.13-31999.76)for starter and finisher respectively,body weight gain(6227.30-8241.20)(10956.64-14182.96)for starter and finisher respectively,feed conversion ratio(1.73-2.26)(2.21-2.48)for starter and finisher respectively.Many(thigh,wings,back)of the carcass parameters measured were not significantly(p>0.05)affected by the treatments but significant difference(p<0.05)was observed in drum stick,breast and neck.However,significant difference(p<0.05)was also observed in gizzard,liver and bile,heart,lungs,legs and head.There was significant difference(p<0.05)in primal cuts per live weight,primal cuts per dressed weight,organs per live weight and organs per dressed weight.In view of the results obtained,it can be concluded that treatment two(10g/10kg)performed better in terms of total body weight(TBW)and feed conversion ratio(FCR).Also in the carcass characteristics,treatment two performed better in terms of breast yield,drumstick,percentage of primal cuts from live weight(P/LW)and percentage of primal cuts from dressed weight.
