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.

摘要

该研究的目的是研究甘露寡糖（MOS）或菊粉对45只HF犊牛的性能和某些生理参数的影响。从对照组开始（15头小牛，未治疗），从年龄的第一天到断奶，15–15头小牛接受了18.7 g /小腿/天的MOS或菊粉补充剂和乳替代品。每天测量饲料摄入量。在第1、14、21和60天监测体重。在第30和60天采集血样，以确定临床化学参数从第15和30天收集的粪便样本中确定主要粪便细菌含量的粪便总数。各组的摄入量，体重和日增重相似。菊粉导致血液中总蛋白质水平降低。粪中总厌氧菌和乳酸菌的浓度与MOS相比，菊粉显着增加了菊粉的含量。与对照相比，菊粉导致粪便中总需氧细菌数量更高。饲喂菊粉的小牛产气荚膜梭菌的细菌计数高于其他处理方法。应该指出，较高（18.7 g /天/小腿）的菊粉或MOS饮食水平参数变化很小，并且不能显着调节犊牛的性能和生理参数。
