Productive performance and cost effectiveness of broiler using three different probiotics in the diet

Abstract

The experiment reported here was an attempt to evaluate the effect of feeding three different probiotics to broilers on productive performance, meat yield and profitability of rearing for 42 days in an open sided house, at Bangladesh Agricultural University Poultry Farm. Two hundred fifty-six one-day old Indian River straight run broiler chicks were randomly allotted to four dietary treatments each of four replicates of 16 chicks each providing floor space of 1115 cm2 per bird. The basal diet was corn-soya and it was supplemented with different probiotics to make test diets. The dietary treatments were: basal diet (T1); basal diet supplemented with probiotic-1 (PB-1) at 1.0 g/kg feed (T2); basal diet supplemented with probiotic-2 (PB-2) at 1.0 g/kg feed (T3); basal diet supplemented with probiotic-3 (PB-3) at 0.5 g/kg feed (T4). Birds were fed starter diet from 0-21 days of age and grower diet from 22-42 days of age. Records were kept of performance traits and carcass yields by maintaining birds under identical management. Profitability was determined on termination of the trial. Performance and carcass yield data were statistically analyzed employing SAS Computer Package Program (SAS, 2009). Results showed no variation (P>0.05) in growth performance and meat yield characteristics of commercial broilers irrespective of types of probiotic supplementation. However, feed intake increased (P<0.05) due to supplementation of probiotics. Although higher cost (p<0.05) incurred due to addition of probiotics in the diet, such an addition increased profit. Profit over control was BDT 12.20/bird (BDT 5.10/kg) in PB-1, BDT 18.70/bird (BDT 7.40/kg) in PB-2 and BDT 17.10/bird (BDT 6.40/kg) in PB-3 group. The profit was higher in all the treated groups over control indicating that the use of probiotics irrespective of type was profitable and cost effective.

Effect of different combinations of probiotic, chicory root powder and coriander seed powder on growth, carcass, immunity, serum parameters and economics of broilers

“…Carcass parameters: The dietary treatments did not to show any significant (P>0.05) difference in slaughter parameters at 42 d of age (Table 3). In agreement with the results of this study, several researchers demonstrated that addition of probiotics (Ray et al 2019), chicory root powder (Praveen et al 2017) and coriander seed powder (Naeemasa et al 2015 andReddy et al 2019) did not result in any significant (P>0.05) effect on slaughter parameters of broilers. On the contrary, few studies indicated significant (P<0.05) effect on slaughter parameters of broilers with probiotics (Panda et al 1999), chicory powder (Izadi et al 2013) and coriander seed powder (Taha et al 2019).…”

Use of cinnamon and Bacillus subtilis probiotics in the diet of broiler chickens

“…Previous studies reported improved meat yield in the diet supplemented with B. subtilis (Molnar et al 2011;Ray et al 2019). Ray et al (2019) reported a non-significant difference between diets with B. subtilis at different levels and the control diet, consistent with the current study.…”

“…Previous studies reported improved meat yield in the diet supplemented with B. subtilis (Molnar et al 2011;Ray et al 2019). Ray et al (2019) reported a non-significant difference between diets with B. subtilis at different levels and the control diet, consistent with the current study. Although there was no significant difference among diets, test diets performed better than the control diet for meat yield traits in which the T 3 had the highest meat yield traits.…”
