Effect of indigenous lactic acid bacteria probiotics on broiler performance

Abstract

The objective of the study was to investigate the effect of supplementation of indigenous lactic acid bacteria probiotics on broiler performance in two different ways application. One hundred and five chicks were placed randomly into seven treatment groups, three replications of five birds each. Chicks in group 1 were unsupplemented birds as a control group (T0). Group 2 was 7 8 daily supplemented 10 cfu/ml/bird of probiotics (T1). Group 3 was daily supplemented 10 9 cfu/ml/bird of probiotics (T2). Group 4 was daily supplemented 10 cfu/ml/bird of probiotics (T3). 7 Group 5 was given 10 cfu/ml/ bird of probiotics in intermittent day supplementation (T4). Similarly to group 5, the way to application of both group 6 (T5) and group 7 (T6) that those were 8 9 supplemented the dosages of 10 and 10 cfu/ml/bird respectively. All of broiler groups fed the broiler basal diet which was formulated to meet nutrient requirements of the NRC recommendation standard and were provided ad libitum. The results shown that cumulative feed consumption of broilers during 28 days of experiment was not different between the control and all of treatments, that those were such as (g/bird) 1306.30, 1485.88, 1359.72, 155.48, 1350.33, 1476.33 and 1307.33 for the T0, T1, T2, T3, T4, T5 and T6 respectively. However the cumulative gain weight (g/bird) between T0 as the control group and the others (T1, T2, T3, T4, T5 and T6) were significantly different (P< 0.05). The cumulative gain weight (g/bird) of all of the treatment groups were such as 611.05 (T0), 707.06 (T1), 702.57 (T2), 754.63 (T3), 722.42 (T4), 772.87 (T5) and 667.34 (T6) respectively. Feed to gain ratios of all experiment groups (T1= 2.12, T2= 1.93, T3= 1.98, T4= 2.00, T5= 2.22 and T6= 2.11) were  of all experiment groups (T1= 2.12, T2= 1.93, T3= 1.98, T4= 2.00, T5= 2.22 and T6= 2.11) were improved significantly (P<0.05) compared to the control group (T0= 2.23). The conclusion of the study can be drawn that both either daily supplementation of indigenous lactic acid bacteria probiotics or intermittent day supplementation affected the improvement of growth performance of broiler chickens when compared to the unsupplemented birds. Daily administration of this probiotics was slightly effective more than intermittent day application when compared to the control. The dosage of 8 probiotics of 10 cfu/ml/bird daily resulted the best broiler performance.
