EFFECT OF Saccharomyces cerevisiae AND ACETOHYDROXAMIC ACID ON GROWTH PERFORMANCE OF INDIGENOUS CATTLE

Abstract

The aim of the study was to evaluate the effect of Saccharomyces cerevisiae and acetohydroxamic acid on growth performance of indigenous cattle. An experiment was conducted using indigenous cattle in Masumpur, Dinajpur, Bangladesh. The experiment was conducted with total 12 indigenous bull aged between 2.0 years to 2.5 years. These bulls were randomly divided into three (3) experimental groups, identified as T0, T1 and T2. Here T0 group was control group and these bulls were reared with ad libitum rice straw and fresh water. T1 group was supplemented with Urit (Acetohydroxamic acid, 2 g in feed/bull/day) with regular ration and ad libitum rice straw and fresh water. T2 group was treated with A-Max (Saccharomyces cerevisiae, 18 g feed/bull/day) with regular ration and ad libitum rice straw and fresh water. The animals were kept in a shed and fed separately. Initial live weight was taken at the start of the experiment and then weekly up to 11 weeks (77 days of age) by using digital balance. In this experiment, the live weight was not significantly differed (P>0.05) among the experimental groups but treatment group exert slightly higher live weight and it was 44.75, 51.25 and 54.00 kg in T0, T1 and T2, respectively. After 11 weeks of experiment average weight gain differed significantly (P<0.05) among the groups and it was 3.73, 4.27, 4.52 kg/day/bull in T0, T1 and T2, respectively. The net income was 3858.02, 5166.83 and 5562.74 Tk. kg in T0, T1 and T2, respectively which shows significantly (P<0.05) higher net profit in treatment groups than the control one. It may be concluded that Acetohydroxamic acid (Urit) and Saccharomyces cerevisiae (A-Max) may have the potentials to improve growth performance of indigenous bull and may be used in beef fattening program.
