Role of protozoa in rumen fermentation, digestibility and nitrogen retention of lambs supplied with or without rumen-protected lysine (DHML-calcium)

Role of protozoa in rumen fermentation, digestibility and nitrogen retention of lambs supplied with or without rumen-protected lysine (DHML-calcium). Kreuzer, M.; Kirchgessner, M. (Inst.

DOCUMENT TYPE: Journal CA Section: 18 (Animal Nutrition) The effects of defaunation and lysine [56-87-1] supplementation on various criteria of digestion and N balance were evaluated in a digestibility trial with 12 wether lambs. The ration (91% conc.) rich in horse beans was fed with or without 0.45% rumen-protected lysine to defaunated and refaunated animals. Defaunation led to a reduced allantoin [97-59-6] excretion and to insignificant effects on the concns. of NH3 and volatile fatty acids in rumen fluid. There were no decisive influences on the molar proportions of volatile fatty acids, on the coeffs. of apparent digestibility or on the N retention. With addnl. Ca dihydroxymethyllysine (DHML-Ca) [75195-64-1], protozoal counts increased, while the formation of various metabolites of fermn. seemed to be slightly reduced. With the exception of crude protein, the apparent digestibilities of the crude nutrients only insignificantly varied. Animals supplied with addnl.In this experiment, several chemicals are used like 75195-64-1 and 97-59-6 lysine retained 52% more N than animals without lysine supplementation. This is due to the increase in N intake and apparent N digestibility and the somewhat lower urinary N excretion with supplemental lysine. There was no distinct interrelationship between defaunation and the supply of DHML-Ca. .
