BOIKOVSKI, S., N. STANCHEVA, G. STEFANOVA and D. DIMITROV, 2002. Composition and properties of the milk in sheep from newly created dairy breed in Bulgaria. Bulg. J. Agric. Sci., 8: 289–293
A subject of study was the milk obtained during the whole lactation of the sheep descending from the herd of the Agricultural Institute – Shumen. There were taken 9 bulk samples from 520 animals during the milk productivity control.
It was established that the dynamism of the whey separation from the coagulum of the sheep's milk was well expressed. The part of the irreplaceable amino acids in the total quantity was 41.32% and of the replaceable ones – 58.68%. The content of lysine was particularly high, which allowed to use it to improve the biological value as a supplement in the foodstuffs of plant origin. The limiting irreplaceable amino acid in the sheep's milk was methionine.
