CHANGE OF INDICATORS OF LIPID-CARBOHYDRATE METABOLISM IN PIGS WHILE USING BETA-CAROTENE PREPARATION
All animals need retinol. It must be dealt with food and the growth of productivity and the development of their body is due to the action of vitamin A, formed from beta-carotene. The problem of rational vitamin provision of agricultural animals is particularly relevant for the households, where not always adequate, poor in vitamins food is used. The need of animals in vitamins increases in critical periods of their life: pregnancy, farrowing or lactating of sows, newbornness and weaning of piglets, stress factors. Preparations betacinol and betaviton, proposed by LLC "Polisintez" (Belgorod), represent particular interest in solving this problem. These preparations are successfully used in the egg and broiler poultry breeding. The aim of work was to determine the influence of beta-carotene preparations betacinol and betaviton on lipid-carbohydrate metabolism in the blood of sows and piglets. Experiments were performed in a tribal Association «Stroyplast-mass-agroproduct» in Ulyanovsk region with sows of large white breed and their offspring. In the experiment were used pregnant and lactating sows and their piglets, from 1-day life up to 60 days old. Preparations were given to piglets before the morning feeding with water of 0,5 ml during 10 days with with an interval in a decade. All experimental animals were clinically healthy and had good fatness. Suckling piglets received preparations with mother's milk, and young of detachable period with water once a day. The results showed that for pigs with their high precocity and synthesis of fat, the role of lipid-carbohydrate metabolism is significant. All the indicators were within the physiological norm and are given in comparison with the control. Under the influence of preparations in pregnant sows there is the use of lipid and reserves of fat depot as a source of energy during fetal development, in lactating sows the preparation betacinol had a normalizing effect, and betaviton - stimulating, increasing the level of lipid metabolism. Thus, the introduction of beta-carotene preparations betacinol and betaviton in the organism of the pregnant and lactating sows, as well as in the body of their offspring - piglets up to two months old -provides stimulation of lipid-carbohydrate metabolism.
