A COMPARATIVE STUDY AMONG THE DIFFERENT STRAINS OF BROILER UNDER FARM CONDITION

Abstract

The study was conducted in poultry shed, under the Department of Dairy and Poultry Science, HSTU. The experimental period was 28th August 2013 to 5th October 2013. The experiment is carried our to select the best strain in the suitable environment in the Dinajpur district. One hundred twenty commercial broiler chicks of different strains (Lohmann, First feather, Hubbard classic and Cobb 500) were randomly divided into four dietary treatment each having three (3) replicates. The number of birds in each treatment was 30 while in each replicate 10. The birds were reared from day 1 to 35 days of age with similar housing, feeding and environmental management condition. The body weight of Lohmann (T1) was significant as compare to fast feather (T2) and the body weight of Hubbard Classic and Cobb 500 were not significant as compare to Lohmann through out the experimental period. After five weeks of rearing body weight were T1 (1948.83g), T2 (1836.25g), T3 (1876.08g) and T4 (1851.65g) respectively. In that case of feed intake there was more or less similer. But T2 (First Feather) intake more (3123.33g) than others. Feed intake after 35 days, T1 (3100gm), T2 (3123.33g), T3 (3056.67g) and T4 (3080gm) respectively. Feed convertion ratio was superior in FCR of Lohmann as compare to fast feather (T2) and Hubbard Classic (T3) and Cobb 500 were not significant as compare to Lohmann (T1). The feed conversion ratio was followed by 1.59 (T1), 1.70 (T2), 1.62 (T3) and 1.66 (T4) respectivly. The variation in survibility among the strains was non significant (P>0.05). Non significant differences were found in dressing percentage among the strains. Abdominal fat, breast muscle is higher in Lohmann than another three strains. It may be concluded that Lohmann broiler performs the best in Bangladesh especially in hot weather than First feather and the perfomance of Hubbard classic and Cobb 500 were more or less similer to Lohmann . The later three strains may also be recommended but priority may be given to Lohmann broiler.
