Seasonal dynamics of lipid content in wool of ukrainian mountain ewes with natural colour of wool covering

V. M. Tkachuk, P. V. Stapay

The data about keratin lipid content in wool of Ukrainian mountain ewes with natural colour of wool covering were presented in the article. It was shown that lipids, which are extract by polar solvents without prior alkaline hydrolysis, consist of 4 fractions of the neutral lipids and 5 fractions of polar lipids. The ratio of these fractions, as their total content depends on many factors, including the season and genotype animals. Pigmented wool, especially gray, contained more total lipids than in white wool. The smallest content of total lipids is in wool of the winter growth, and the largest - in summer-autumn period.
