Abstract

The study determines the reliability, direction and strength of the relationship between the main components of the milk of Lacon sheep (n=96) and Saanen goats (n=134). It was found that the nature and direction of the relationship between MFF and other components of milk in goats and sheep were similar. Between MFF and TTP, casein, the content of fatty acids, both saturated (SFA, LCFA, STsFA) and unsaturated (MUFA, PUFA, SCFA), an average and high positive relationship was revealed. At the same time, it was more pronounced in sheep milk (r = 0.41 ... 0.97) than in goat milk (r = 0.38 ... 0.84). For goat and sheep milk, a high positive (r = 0.95 and 0.99), i.e. functional, relationship between the content of casein and TTP was revealed. No relationship has been established between the number of somatic cells (CSC) and other components in sheep milk and goat milk. Also, there was no relationship between the differential number of somatic cells (DKSK) and other indicators, with the exception of the number of somatic cells and lactose content, as in the milk of sheep and goats. The study was carried out within the framework of the complex project “Scientific and technological frontiers” of the strategic academic leadership program “Priority 2030” on the topic “Biotechnological methods of reproduction and genomic technologies in the selection of farm animals and the conservation of the gene pool of small in number breeds”.
