USE OF VEGETAL LECITHIN IN THE RATIOS OF MILKING SHEEP AND GOATS

Abstract

With the purpose of increasing the milk production at milking sheep and goats they were given a supplement of vegetal lecithin, residue (mucilage) from manufacturing the soy and sunflower, which was administrated in the morning, in the drinking water (100/200 ml mucilage), after a previous dilution with warm water in a proportion of 1/1. At all experimental lots of sheep and goats the total milk production of milk increased with 5-12%, even if sometimes the production of merchandise milk had close values between the experimental and witness lots, in a few cases even, this being due to the lactation period, which was also variable. It was determined the chemical composition of the sheep and goat milk and it was noticed that at the experimental lots, which received a plus of vegetal lecithin in the fodder ratios there were determined higher values at the dry substance, fat and protein, however the changes were not constant during determination and sometimes the values were equal with those from the witness lot or even inferior to these. It was determined the structure of the fat of milk and it was noticed an increase of the content of non-saturated fat acids in the case of the experimental samples which came from the animals that received vegetal lecithin in their ratios comparatively with the content determined at the milk of animals from the witness lot.
