Antiprotozal composition

A method of increasing the facultative bacterial population in the rumen of a ruminant animal by controlling, reducing or preventing the growth of protozoa in the rumen, comprising feeding to a ruminant an antiprotozal amount of a composition comprising Corynebacterium cell bodies, Brevibacterium cell bodies, said cell bodies having antiprotozoal activity and are disposed to drive fermentation to yield glutamic acid fermentation solubles, or corn fermentation solubles, and glutamic acid.

A method for controlling, reducing or preventing the growth of protozoal bacteria in the rumen of a ruminant comprising feeding an antiprotozoal amount of a composition comprising facultative anaerobe Corynebacterium cell bodies and Brevibacterium cell bodies, glutamic acid fermentation solubles, ans corn fermentation solubles to a ruminant;

• said cell bodies and solubles having been dried to a total moisture content of less than 30% by weight at a temperature not less than about 80° F. and not more than about 900° F., said cell bodies and said fermentation solubles having antiprotozal activity when introduced to the rumen of the ruminant.

A composition for controlling, reducing or preventing the growth of protozoal bacteria in the rumen of a ruminant comprising cell bodies of a facultative anaerobe selected from the group consisting of Corynebacterium cell bodies and Brevibacterium cell bodies or a mixture of Corynebacterium cell bodies and Brevibacterium cell bodies, glutamic acid fermention solubles, corn fermentation solubles, glutamic acid -fermentation solubles and corn fermentation solubles.
