Abstract:
The objective of the study was to evaluate performance of crossbred calves supplemented with Probiotic and Exogenous Fibrolytic Enzymes under intensive system. In a completely randomized design, 24 growing calves were divided into 3 equal groups of eight each. APBN-1 was fed ad libitum and concentrate feed @1% of their body weight to all the calves. A basal diet was fed to one group (T1) and is supplemented with RumEest-ESF@ 10g/animal/day (T2) and 15g/animal/day (T3). All haematological parameters like RBC, WBC, Hb, PCV, MCV, MCH and MCHC were non significantly higher (P>0.05) in Probiotic and EFE groups. Supplementation of Probiotic and EFE did not show any significant difference among the groups pertaining to serum glucose, total protein, albumin, globulin, BUN, creatinine, cholesterol and triglycerides and also on serum enzymes AST and ALT (U/L). The similar trend was observed in the serum macro minerals (Ca, P and Mg). The faecal consistency scores for T1, T2 and T3 were 1.50± 0.27, 2.63 ± 0.18 and 2.88 ± 0.30, respectively and found to be significant (P<0.05) among treatment groups. It was concluded that supplementation of EFE and live yeast culture at 15 g/animal/day could improve the and faecal consistency score with no effects on haemogram and blood biochemical parameters. The combination of fibrolytic enzyme and live yeast culture improved rumination capacity of animal which gives a positive indication for reduction of diarrhoea and in turn productive performance.
