THE RUMINANT EFFECT OF VEGETAL LECITHIN AT SHEEP AND GOATS

Abstract

In the extraction process of the vegetable soy oils and sun-flower oils results
in large quantities a waste that contains approximately 45% fat from which
58% is lecithin. This waste called “dreg” creates problems of environment
pollution because we didn’t find a use for it. We tested this waste in the food
of small ruminants, at sheep and goat, watching the ruminant effect and the
apparent digestibility of the nutritive substances in the food. The tested doses
of “dregs” were of 100 g and 200 g per day. The food supplementation in
sheep and goats with dregs up to 7% fat in the dry substance of the ration
has favourable and proportional effects with the dose of fat on the
digestibility of the nutritive substances from the food. The growth of
ruminant bacteria is favoured at the 100 g dose of dregs but is depressed at
the 200 g dose of dregs. On the ruminant protozoa the supplementation with
fat from dregs leads to the reducing of the number of protozoa and even at
defaunation. It is possible that the fat from the dregs to be a source of YATP
and to protect the alimentary proteins of the degrading with proteolytic
enzymes and therefore to make the protein ruminant by-pass.
