Abstract:

This study was conducted to find out the efficacy of probiotic (Bacillus subtilis) on growth performance and carcass traits of broiler birds. The experiment followed completely randomized design in which the day old broiler chicks (n=180) were divided into 4 dietary treatment groups (T1-T4) as 3 replicates of 15 chicks in each. The chicks of four different groups were fed with basal diet, antibiotic growth promoter (Enramycin @ 250 mg/kg feed) and commercial probiotic containing 3 strains of Bacillus subtilis (DM 03, TAM 4 and IQB 350) spores at the concentration of ½ million/g and 1 million/g of finished feed, respectively. The productive indicators evaluated were: body weight, feed consumption and feed conversion ratio (FCR). The carcass quality traits were also determined. The supplementation of Bacillus subtilis (1miilion/g of finished feed) resulted in highly significant (P<0.01) increase in the body weight of birds as compare to control (T1) during 4th and 5th weeks of experiment. The feed consumption recorded lower in T4. The addition of Bacillus subtilis based probiotic and AGP showed highly significant (p<0.01) variation regarding weekly FCR during 3th and 4th week. The weight of liver, heart and intestine and the weight of different cuts (thigh, wing, and back) as percent of live weight accounted non-significant variations among different groups. However the weight of breast as per cent of live weight was highly significant (P<0.01) between the groups and found maximum in T4 group.
