Abstract

Nine ruminally fistulated yearling steers were used in a 9 x 2 Incomplete Latin square to evaluate benefits of an increase in dietary Rumensin level during an imposed acidosis challenge. Feeding Rumensin, at either 30 or 45g/ ton reduced acidosis on the challenge day. However, increasing the dietary Rumensin concentration to 45g/ton was required to reduce acidosis for the five days following that challenge. Feeding 45g/ton reduced ruminal pH area below 5.6 when compared to the normal level of 30g/ton during the five days following the challenge.
