Abstract

In the present study, the physiological effects of bentonite powder as a feed additive were investigated in beef cattle. During a four-month experimental fattening period of Angus breed cattle, the animals certainly consumed the bentonite powder spread on the feed. In a fattening experiment of beef cattle, the growth properties, the fattening efficiency, the toxin contamination of the feed and bedding straw, and the amount of ammonia and clostridium bacteria excreted in faeces were examined, with the addition of 150 g/day/individual bentonite. The IBM SPSS Statistics 22.0 program was used to process the collected data. According to the results, the bentonite supplementation had a positive effect on both the fattening performance and fattening efficiency of beef cattle. In addition, the amount of ammonia excreted in faeces decreased, while the amount of excreted clostridium bacteria increased. Due to the improved feed utilization, the specific feed cost of the fattening cattle decreased by 11.8% compared to the control group. As a further positive effect, bentonite reduced the amount of environmentally harmful ammonia in the faeces, and increased the excretion of the bacterial flora in the faeces, which has a negative effect on the digestive system.
