Influence of feed factors on the dynamics of sow metabolism

Abstract

The article presents the results of studies on the effect of increased fiber levels in combination with the probiotic Profort in SK-1 mixed feed on the formation of metabolism in the body of pregnant sows, in SK-2 mixed feed on the formation of microbiocenosis and nonspecific immunity in lactating sows in the conditions of the pig complex LLC "Agronika" of the Kursk region. The tested mixed feed SK-1 has an optimal structure of feed ingredients, which corresponds to the physiological state of deepfat sows. At the same time, the fiber content increases to 8.0%, the crude protein content is 176.3 g / kg at the exchange energy level of 10 MJ/kg. The SK-2 compound feed for lactating sows contains 12.87 MJ / kg, crude protein-18.3%, crude fat-4.86%, crude fiber-4.93%. The studies found that the blood serum of the experimental group of pregnant sows significantly (P < 0.05) higher glucose and total protein, the tendency of growth of gamma-globulins indicates an increase in the immunological reactivity of the sow body. There is a tendency to increase a-globulins and b-globulins. Indicators of enzyme activity in-dicate the intensity of metabolic processes in the body of deep-fat sows. The indi-cator of alkaline phosphatase, in the experimental group, tends to increase by 2.8 times, the decrease in the indicator of the amylase enzyme in the experimental group by 1.2 times. Increased lipase activity in the experimental group by 2.2 times. In studies of the facies environment of lactating sows, a positive trend of re-ducing the conditionally pathogenic microflora was established, while an increase in Bifidobacterium to 107 CFU/g was found, with a decrease in E. from 60 to 105 CFU / g, which indicates a positive dynamics of microbiocenosis due to an increase in normal microflora. Th ratio/Ts in the blood of sows of the experimental group increased due to an increase in the number of T-helpers by 73.8% , while reducing T-suppressors by 85.9 %. An increase in the blood content of animals of the second group of G-class immunoglobulins indicates a decrease in the antigenic load on the body.
