The study aim was to determine prebiotic (inulin) and new synbiotic (inulin and Enterococcus faecium) varied dosage effects, during food breakdown-abomasum immunoreactive (IR) cell amount and cold carcass weight. Ghrelin is synthesized in the fundus region of the stomach. In the gastrointestinal system, ghrelin affects multiple functions, including secretion of gastric acid, gastric motility, and pancreatic protein output. The study consisted of 49 Holstein male calves (23 ± 5 days old, 50 ± 5 kg). Control and experimental groups were differentiated only with the additive amount added to the morning food source. Three prebiotic groups were fed Jerusalem artichoke flour (inulin content increased by 50%) in three amounts: 6 g (lowest) PreG6, 12 g (medium) PreG12, and 24 g (highest) PreG24. Three synbiotic groups were added 0.25 g of prebiotic Enterococcus faecium (2∗109 CFU/g) to the respective prebiotic, obtaining a new synbiotic (SynG6, SynG12, and SynG24). Calves were slaughtered after 56 days to obtain abomasum samples for ghrelin IR cell examination, and carcass weight was determined. It shows that ghrelin IR cell count in the abomasum was (p
