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.
