Comparative effect of different amount of inulin and symbiotic on growth performance and blood characteristics 12 weeks old calves
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.
