Effect of the complex feed additive " Beta -Carotene Complex" on biochemical blood parameters during the transition period

Feeding cows after launch requires special attention, since during this period there is an intensive growth and development of the fetus, so most of the nutrients entering the cow's body are spent on its development. In addition, there are strong hormonal changes, as preparations for childbirth are underway. Therefore, it is very important that the animal receives the necessary amount of nutrients during this period so that the fetus develops harmoniously, the birth takes place without complications, and the cow's recovery after calving is faster. The Beta-Carotene Complex (KBK) has proven itself well in dairy cattle breeding for lactating cows. Therefore, the aim of the study was to study the effect of the complex additive "KBK" for cattle on the biochemical parameters of cow blood during the transit period.The research was conducted in the conditions of animal husbandry in the Pskov region. The object for research is cows during the transit period. For the study, 2 groups of animals with 10 heads each were formed. The animals of the experimental group were given the "KBK" supplement in accordance with the draft instructions for use. The feed additive was dissolved in warm water at the rate of 300 ml per 25 liters of water for 15 days before calving. To study the effect of the feed additive, in addition to assessing the clinical condition of the animals, biochemical blood tests were performed 7 days before the start of giving the KBK feed additive, on the 9th day after the start of giving and on the 7th day after calving. As a result of the conducted research, the positive effect of the complex feed additive "KBK" on cows during the transit period has been established. This could be observed both by the clinical condition of the animals of the experimental group and by the results of biochemical blood parameters.
