Effect of Dietary Supplementation of Probiotic on Growth Performance, Hemato-biochemical Profile and Parasitic Infestation of Broilers

Abstract

The aim of this study to investigate the effect of dietary supplementation of probiotics on growth performance, hemato-biochemical profile and parasitic infestation of broilers. For this, total 240 day old chick (Cobb-400 strain) were used for the study purpose and divided into four groups and three replication, twenty chicks in each. The group first was acted as a control group, second was supplemented probiotic @ 0.5 g/kg feed, group third was supplemented probiotic @ 1.0 g/kg feed and group fourth was supplemented probiotic @ 1.5 g/kg of feed. Blood samples were collected end of trial. Feed consumption, Body weight, Body weight gain, Feed conversion ratio, hemoglobin, packed cell volume, total erythrocyte count, total leukocyte count, total protein, albumin, globulin, glucose, cholesterol and carcass quality were estimated. The average feed consumption was found 2571.90±24.11, 2537.14±20.31, 2523.81±18.96 and 2519.05±21.99 g in Control, T1, T2 and T3 group, respectively. Feed consumption was observed non significant the groups. The average body weight was found 1715.34±15.75, 1732.90±15.84, 1749.02±14.25 and 1818.51±17.03 g in Control, T1, T2 and T3 group, respectively. Body weight was observed significant (P<0.05) among the groups. The average body weight gain was found 222.20±32.22, 220.78±23.27, 207.50±39.39 and 212.83±32.22 g in Control, T1, T2 and T3 group, respectively. Body weight gain was observed non significant among the groups. The average feed conversion ratio was found 11.63±0.64, 11.57±0.70, 12.20±0.51 and 11.88±0.57 in control, T1, T2 and T3 group, respectively. Feed conversion ratio was observed non significant (P<0.05) among the groups. Plasma haemoglobin concentration was significantly higher (P<0.05) in T1 and T2 groups as compared to T1 and control groups of broiler birds. Packed cell volume was higher in treatment groups but there was no significant difference observed among the T1, T2and T3 groups of broilers. Total erythrocyte counts and total leukocyte counts were higher (P<0.05) in treatment groups but there was no significant difference observed between T1 and T2. Monocyte % was higher in 1.5 g/kg feed probiotics supplemented groups as compared to other group of broilers. In present study lymphocyte % was significantly higher in probiotics treated groups but highest value was reported in 1.5 g/kg feed probiotics supplemented group of broiler birds. Total protein was observed highest in 1.5 g/kg feed probiotics suppleneted groups as compared to other groups of broilers birds. Whereas T2 and T3 groups has significantly higher total protein value as compared to T1 and control groups. Plasma concentration of albumin was differed significantly (P<0.05) among the groups. Highest level of albumin reported in T3 groups. Circulating concentration glucose was significantly higher in probiotics treated groups but highest level reported in T3 group of broiler birds. Glucose level did not differ significantly between T1 and T2 groups. Total cholesterol concentration was lower (P<0.05) in T3 groups as compared to other groups of broilers. Dressing percentage was significantly higher (P<0.05) in probitics @1.0 and 1.5 g/kg feed supplemented groups as compared to other. Eviscerated weight was significantly higher (P<0.05) in T2 and T3 than T1 and control groups of broilers. Overall prevalence of helminth parasites was reported minimum in 1.5 g/kg feed probitics supplemented group. The study was concluded that probiotic supplementation improved the feed consumption, body weight, body weight gain, feed conversion ratio, hemoglobin, packed cell volume, total erythrocyte count, total leucocyte count, total protein, albumin, glucose and decreased total and parasitic load.
