EFFECTS OF G-PROMIN AND ACIFY ON THE PERFORMANCE OF BROILER

Abstract

The experiment was conducted with a view to observe the effects of G-Promin, Acify and their combination on the performance of broilers at a private poultry farm located at Bogra with commercial Cobb-500 broiler for a period of 5 weeks. A total number of 200 one-day-old straight run broiler chicks were distributed to five dietary treatments i.e. fed the basal diet (control — To), whereas in other treatment groups basal diet was supplemented with G-Promin @2.5 mi/litre of drinking water once a day at 2" week and 4" week (T;), combination of G-Promin @ 2.5 ml G-Promin/litre of drinking water once a day and Acify @ 5 ml/ kg feed at 2™ week and 4" week (T2), combination of GPromin @ 2.5 ml G-Promin/litre of drinking water once a day and Acify @7 ml / kg feed at 2™ week and 4" week (T3), and Acify @ 5 ml/kg feed at 2"! week and 4'" week (T,). Body weight gain, feed conversion ratio (FCR), mortality and carcass characteristics were recorded. The final body weights of birds improved significantly (P<0.01) in T3 compared to other treatments groups. Feed consumption not differed significantly. Feed conversion ratios differed significantly (P<0.01) at the age of 5" weeks. Feed conversion ratio were 1.938, 1.717, 1.686, 1.626 and 1.840 in To, T1, T2, T3 and T4 treatments respectively. Profit/broiler or profit/kg broiler differed significantly (P<0.01) among differents treatments. It may be concluded from the study that combination of G-Promin @ 2.5 ml G-Promin/litre of drinking water once a day and Acify @7 ml / kg feed at a week and 4" week (T4) was found better performance in respect of live weight gain and feed conversion.
