Wool growth and sulfur amino acid entry rate in sheep fed roughage based diets supplemented with bentonite [clay] and sulfur amino acids.

Fenn P.D. | Leng R.A.
In experiments to test the hypothesis that by protecting amino acid supplements in the rumen, and increasing their absorption unchanged from the intestine, complexing them with bentonite should increase wool growth, it was found: (a) that cysteine in any form, solid, dissolved or complexed, was apparently liable to ruminal degradation; (b) that methionine with drinking water apparently survived the rumen, was absorbed in the intestine, and increased wool growth; (c) that bentonite alone, as powder or in water, increased wool growth, but not the entry of cysteine or methionine into the blood; (d) that bentonite mixed or complexed with the amino acids did not increase wool growth beyond the effect of each supplement alone.
