Abstract

ABSTRACT The objective of the study was to examine the effects of mannanoligosaccharide (MOS) or inulin on fourty-five HF calves’ performance and certain physiological parameters. Next to the control group (15 calves, no treatment), 15–15 calves received 18.7 g/calf/day MOS or inulin supplementation with milk replacer from 1st day of age to weaning. Feed intake was measured daily. Body weight was monitored on days 1, 14, 21 and 60. Blood samples were taken on days 30 and 60 to determine clinicochemical parameters Total faecal counts of the main faecal bacteria contents were determined from faecal samples collected on days 15 and 30. Mean feed intake, body weight and daily weight gain were similar in the groups. Inulin caused lower total protein level of the blood. Faecal concentration of total anaerobic bacteria and Lactobacillus was significantly increased by inulin compared to MOS. Inulin caused higher total aerobic bacteria count in faeces compared to control. The germ count of Clostridium perfringens from calves fed inulin was higher than that of other treatments. It should be stated that higher (18.7 g/day/calf) dietary level of inulin or MOS had minor alterations in parameters and failed to significantly modulate performance and physiological parameters of calves.

Highlights

Calf diarrhoea, causes serious problems in the early stage of life and according to Gulliksen et al (2009) it increases the risk of calf mortality
Inclusion of prebiotics in the milk replacer had no effect on calf starter intake during the study (Figure 1)
Calves receiving milk replacers supplemented with MOS or inulin did not present differences in body weight and daily body weight gain (Table 4)

Summary

Introduction

Causes serious problems in the early stage of life and according to Gulliksen et al (2009) it increases the risk of calf mortality. The use of antibiotics has been a typical practice in animal husbandry for disease prevention and control. Prebiotics have been proposed as alternatives because these materials have wide-ranging physiological effects on gut function, activity of the large intestinal microflora, mineral absorption, lipid homeostasis, and immunity (Samanta et al 2013). Inulin increased the body weight gain (BWG) and slightly improved the feed conversion ratio while decreased the length of intestinal villi and the number of goblet cells and proliferating cells and caused changes in physiological parameters of blood (Masanetz et al 2010, 2011)
