Abstract

It was reported in the previous paper of this series that pronon, a polypropylene glycol derivative, had a remarkable effect for the prevention of bloat, as compared with several antifoaming agents. In the present study, pronon-absorbed cocoanut grounds were examined for practical effect of controling bloat. Thirty-four ewes were used made at the Iwate Livestock Breeding Station in July, 1962. Experimental animals were fed a ration containing 10g of pronon-absorbed cocoanut grounds and 100g of wheat bran per head per day. Controls were fed a ration containing 100g of wh eat bran. Then they were grazed on a Ladino-clover pasture.
One of the experimental animals was not affected with bloat, but ten control animals suffered from acute bloat. Pronon prevented bloat for twenty-four hours after feeding. The surface tension and the foaming rate of rumen juices decreased significantly after pasturing. The results showed that pronon might be a marked preventive for acute foamy bloat in ruminants.
