Abstract. The purpose of the research was to study the influence of high content of crude fiber and Cellobacterin probiotic with the reduction of the exchange energy level in the diet of pregnant sows on the state of the overall metabolism and intestine microbiocenosis in the second half of gestation. The modified compound feed SK-1 with the level of exchange energy of 10.0 MJ/kg increased the fiber content in the feed up to 8.0%, crude protein – up to 176.3 g/kg. The application of feed with Cellobacterin and increased fiber content during the period of deep gestation had a pronounced positive effect on the formation of the metabolic status of the pregnant sows’ organisms. On the 70th day of gestation the average content of the crude protein significantly increased relative to the control group from 79.6 g/L to 85.9 g/L; on 100th day it increased from 73.1 g/L to 80.6 g/L, respectively; the content of total globulins increased by 3.2% and 4.4%, respectively. The amount of total lipids in the blood serum of the sows from the experimental group increased significantly by 1.2 g/L and 0.7 g/L, respectively to the gestation periods, that was associated with an increased concentration of fiber in the tested feed. The experimental group showed an increase in the content of enzymes involved in metabolism relative to control. The content of alkaline phosphatase increased 2.8 times; creatine kinase – 1.7 times; lipase – 2.2 times. We revealed a positive trend of decreasing conditionally pathogenic microflora population in the digestive tract. Staphylococcus sp. and Clostridium spp. reduced to 10E3 CFU/g; Proteus vulgaris and Enterococcus faecalis decreased to 10E2 CFU/g, while the amount of Bifidobacterium increased to 10E7 CFU/g. The population of Escherichia coli decreased to 10E5 CFU/g, indicating the positive changes in intestinal microbiocenosis. The share of heavy litter in the experimental group increased insignificantly by 4.5%, whereas the absolute milk yield increased significantly from 310.9 kg to 354.7 kg (by 14.1%).
