Effect of Dietary Inulin, Bacillus Subtilis Based Probiotics and Its Synbiotic Combination on Performance, Nutrients Utilization and Health in Barbari Goats

Abstract

The aim of the study was to investigate the effect of dietary inulin, Bacillus subtilis based probiotics and its synbiotic combination on performance, nutrients utilization and health in barbari goats. For the study twenty-four healthy barbari goats of similar age and weight were taken from Livestock Farm Complex II (LFC II), SVPUAT. The nutrient requirements of barbari goats were met by feeding concentrate mixture, wheat straw, and available fodder as per NRC standards of nutrient requirements for goats. They were allocated into four groups with six animals per treatment distributed based on their live body weights using completely randomized block design. The control group was fed on basal diet without any supplementation and Treatment group T1 fed with basal diet which was supplemented with 2% inulin (Fibrelite) on dry matter basis, T2 fed with basal diet which was supplemented with B. subtilis (BaciplusR) (2 x 109cfu/kg), and T3 fed with basal diet which was supplemented with Synbiotics combination of 2% Inulin on DM basis and B. subtilis (2 X 109cfu/kg). The results showed that there was an increase in dry matter intake in T3 group supplemented with synbiotic followed by T2 probiotic, T1 prebiotic and control group respectively. The mean daily body weight gain was higher in group T3 followed by group T2, T1 and control group. The body condition score of experimental goats were improved in synbiotic treated group compared to control, T2 and T1 group during the trial period. The supplementation of inulin, Bacillus subtillis and its synbiotic were not visually changes in faeces. The supplementation of inulin , Bacillus subtillis and its synbiotic had no adverse effect on biochemical parameters. The average parasitic load of faecal sample was lowest in T1 group as compared to T2 and T3 group. The results of the study suggested beneficial effects of inulin, Bacillus subtillis and synbiotic supplementation in growing goats.
