The article presents the materials obtained in the study of the effect of additional fertilizing on the digestive processes and the natural resistance of the body of Karakul sheep with year-round pasture content. We found that sheep and goats that grazed on the pasture for a quarter of a year, regardless of their physiological state, are on half-starved rations, especially in the second half of suyagnost and at the beginning of the spring period. During these periods, the sheep of both groups compared in the winter period daily received from 0.70 to 0.78 energy feed units and from 20 to 28 g of digested protein, and at the beginning of the lactation period, these indicators were 86% of the norm, i.e., they received from 13 to 17% of nutrients. In this regard, we conducted experiments to study the effect of a household diet consisting of coarse feed: 130 g of mixed feed, 50-50% of barley and straw cutting and pasture feed. The sheep of the experimental group received an almost balanced diet for all nutrients. According to the data obtained, the composition and nutritional value of the diet consumed by sheep of the experimental group of feed practically meets their need completely, and in animals of the control group-only 82-85% of the nutritional needs. The highest concentration of total nitrogen was in the rumen of the experimental group – 123.33 mg%, while in the Queens of the control group, its concentration averaged 110.0 mg % or was 12.1% less. In the control group of Queens with a higher consumption of pasture feed, the digestibility of the main nutrients was lower compared to the animals of the experimental group. Inadequate feeding negatively affects the severity of the level of natural resistance.
