Thesis Title: “Effect of supplementing mannan oligosaccharide on the performance of Muzaffarnagari sheep”
ABSTRACT
18 Muzaffarnagari sheep of similar age group were taken from Livestock farm complex II (LFC II), SVPUAT. The animals were separated randomly into 3 groups. 1st group was treated as control. 2nd and 3rd groups were taken as treatment group. 2nd and 3rd groups were supplemented with mannan oligosaccharide at the rate of 2% and 4% on dry matter basis, respectively along with basal diet. The basal diet comprised of wheat straw, chaffed green berseem fodder, jowar fodder and compounded concentrate mixture at a ratio of 30:15:15:40. Concentrate mixture was prepared by mixing barley grain, wheat grain, oat grain, wheat bran, gram chunni, mustard oil cake and mineral mixture in 20, 20, 10, 10, 10, 28 and 2 parts, respectively.Fortnightly body weight, dry matter intake, weight gain, ADG, FCR and faecal scorewererecorded during the trial period.Blood samples were also collected at 30 days interval i.e. day 0, 30, 60, 90 post supplementation. Haematological parameters were analysed in fresh blood samples. Blood biochemical parameters are estimated in blood plasma. The average BW and metabolic BW of all the fortnights were not significantly different (P>0.05) between groups. The overall gain (kg) and daily weight gain (g/d) was found significantly higher (P<0.01) in both the treatment groups than control. T1 group of animals showed higher BCS than control in fourth, fifth and sixth fortnight. The overall BCS was found higher in T1 group than control. Treatment groups were found to have lower faecal score than control.Digestibility of different nutrients was found similar. Digestible DM, OM, EE, NFE, CF, NDF and ADF intake were found similar in all the three groups of experimental animals. Dry matter intake (%BW) was higher in T1 than control. But total DM intake (kg/d) was found similar. TDN (g/kg W 0.75) intake similarly found similar in all the three groups.Overall Plasma cholesterol concentration was found lower in T2 group than control. But, HDL cholesterol value of T1 and T2 groups were found similar to control throughout the trial period. Plasma TIg concentration was found to increase in T2 group than other. BUN and creatinine concentration of all treatment groups was found similar with control. Liver enzyme activity was also found similar as the activity of ALT, AST and ALKP remained similar throughout the trial period. Thio barbituric acid reactive substance activity of T2 group was found lower than others but plasma FRAP value in present study was found similar in all the experimental groups. In conclusion, Mannan oligosaccharide up to the dose rate of 4% of dry matter improved growth performance, immune parameters, feed intake and feed efficiencyof Muzaffarnagari sheep without adversely affecting blood metabolites and liver function.
