Analysis of biochemical indicators of blood serum of lactating sows when using “Liquafide”

Modern industrial pig farming involves the intensification of production and the search of methods to reduce costs in the production of pork, observing veterinary and sanitary requirements. All this is aimed at solving the issue of food security of the country and solving the issue of import substitution. Nevertheless, the intensification of pig farming is accompanied by a violation of the physiological needs of the animal's body, as well as a decrease in its resistance and exacerbation of existing diseases. A healthy metabolism in the body of lactating sows lays the foundation for the further health and productivity of her offspring. The purpose of the study was to assess the effect of different doses of the «LikvaFid» supplemental nutrition complex on the biochemical parameters of the blood of sows during lactation. During the experiment, biochemical parameters were analyzed: total protein, albumins, globulins, alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase, urea, total cholesterol, triglycerides, calcium, phosphorus, magnesium, iron, zinc and copper. To conduct the experiment, 4 groups of analogues were formed from sows with a history of 2 to 5 farrowing. The first experimental group (n = 10) of sows received the probiotic additive «LikvaFid» at a dose of 40 g, the second (n = 10) – 50 g and the third (n = 10) – 60 g per 1 ton of consumed water. The animals of the intact group (n=10) did not receive a probiotic supplement. Blood sampling from all sows was performed once from the jugular vein before weaning the young. According to the results of the study, it was found that the use of different doses of the probiotic complex «LikvaFid» to sows during lactation has a beneficial effect on the biochemical parameters of blood serum. The studied indicators characterizing protein and lipid metabolism mainly did not go beyond the reference values, which indicates the physiological course of metabolic processes in the body of sows. Against the background of the use of «LikvaFid», hepatocellular metabolism is normalized and the concentration of vital micro- and macronutrients increases. Positive changes in the biochemical composition of sow blood are associated with normalization of the intestinal microbiome and improved absorption of nutrients throughout the gastrointestinal tract.
