The Effect of Additional Feeding On the Processes of Digestion and Natural Resistance of the Sheep Body in Pasture Conditions

Abstract

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.
