Abstract
The experiments of nutrition made through introduction of the vegetal lecithin contained by the residue from the processing of the soy and sunflower in the fodder ratio of sheep and goats determined the elaboration of a technological solution in order to increase and improve the milk production of sheep/goats, of the quality of the sheep/goats milk. By introducing the vegetal lecithin in the fodder ratio of the sheep and goats during lactation period it was made an increased production of milk, an increase of the total production with 39.38% at the Merinos de Palas sheep, with 10% at the sheep from milk population of Palas and with 14% at the goats of Carpathian breed and an increase of the production of merchandise milk with 49% at the Merinos de Palas sheep, with 13% at the sheep from milk population of Palas and with 16% at the goats of Carpathian breed. The introduction of a daily quantity of 100 g of raw lecithin in the food of sheep and goats has generated the nutritive modifications of the fodder ratios. The vegetal lecithin administrated in the ratios of sheep and goats during lactation is a technological solution of increasing and improving the milk production, at the experimental lots being noticed an increase of the percents of dry substance, fat and protein. The experiments made to verify the technological parameters at the processing of cheese emphasized an improvement of the technological characteristics of the milk, contributing to the increase of the yield with 20% at the goat milk from the experimental lot, and at sheep with 7%.

Key words: sheep, goat, vegetal lecithin, milk production
