Abstract

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 < 0.05) reduced in 6g and 12g inulin dosage, but carcass weight was significantly (p < 0.05) higher for PreG12 and PreG24 (p < 0.05) and then for CoG (CoG 42.6 kg; PreG12 51.4 kg; and PreG24 54.0 kg) and (p < 0.05) for SynG12 and SynG24 (SynG12 52.3 kg and SynG24 49.6 kg), which indicates longer satiety and more wholesome breakdown of the food uptake. It was concluded that ghrelin IR cells in 12-week-old calves are more abundant in the fundus region. Medium- and high-dosage prebiotic inulin feeding to the calves improves overall food digestion, allowing for longer satiety and higher cold carcass weight without increasing food amount. Adding synbiotic 0.25 g Enterococcus faecium (2∗109 CFU/g (Protexin, UK)) to inulin (produced in Latvia LTD „Herbe”) does not improve the results of this prebiotic.

Summary

Introduction

Academic Editor: Remo Lobetti e 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. Calves were slaughtered after 56 days to obtain abomasum samples for ghrelin IR cell examination, and carcass weight was determined. Medium- and high-dosage prebiotic inulin feeding to the calves improves overall food digestion, allowing for longer satiety and higher cold carcass weight without increasing food amount. Introduction e search for methods in agriculture animal farming continues to find methods to increase farm animal growth, development, and productivity, as well as disease prevention without the use of antibiotics [1] It is important for cattle growing, when calves transition from milk being their main source of protein digestion in the abomasum to digestion of roughage and concentrates in the foregut. With increased food digestion and absorption in animals with identical nutrient uptake, hunger decreases that lowers ghrelin immunoreactive (IR) cell activity. Ghrelin is known as a hunger signal from peripheral tissue, which indicates ghrelin IR cells are affected by peripheral cell metabolism [12, 15]
