Abstract:
The study was focused on assessment of the effect of prebiotic inulin (from Jerusalem artichoke (JA) powder it contain ~50% of inulin) and mixed with probiotic preparation call synbiotic thereof on growth performance and blood parameters of milk calf. In total, 70 milk calves (50+/-5 kg; 23+/-5 d.old) were used in a 57-d experiment. The seven dietary treatments consisted of the control diet (CoG); diet CoG supplemented with different amount of prebiotics (PreG6; PreG12; PreG24; accordingly 6g, 12 or 24 g of JA) and three different amount of synbiotics (SynG6; SynG12; SynG24; accordingly inulin and probiotic 0.25 g Enterococcus faecium (2×109 CFU g-1). Throughout the study prebiotic (PreG) and synbiotic (SynG) groups calf average daily gain (ADG) was increased (p < 0.01) than CoG, the end of study the highest ADG reached PreG12 than SynG12 and it was (p < 0.01) compare with CoG. At the end of te study PreG6 and SynG6;12 hematocrit was higher (p < 0.05), but PreG12;24 and SynG24 (p < 0.01) than CoG. Hemoglobin PreG and SynG12;24 was higher (p < 0.01) compare with CoG. WBC was lower (p < 0.05) PreG24, but there were no differences between synbiotic groups (SynG) compare CoG. PLT was (p < 0.01) higher PreG and SynG supplemented groups than CoG. Total protein PreG12; SynG6;12 (p < 0.01) higher compare CoG. Glucose PreG6;12 is lower (p < 0.05) than CoG. In conclusion, 12g and 24g of JA powder and the same amount ja powder mixed with probiotic Enterococcus faecium can improve the 4 to 12 weeks old calf performance and health status. However, new synbiotic didn’t improve inulin action.
