PHYTОPREPARATIONS EFFICIENCY IN THE COWS NUTRITION

Abstract

In order to increase the intensity of livestock development and obtain safe products such as meat and milk, it is of great importance to provide cows with qualitative feed and optimal maintenance. An important role is devoted to the animal health because it directly affects productivity. The use of poor quality feeds leads to animal health deteriorating, reduced productivity. Dis-balance of the gastrointestinal microbiota leads to poor food intake and clinical manifestations of disease. In order to increase feed efficiency and productivity indexes, were used extracts of essential oils contained in the feed additive "Activo". This supplement with its properties stimulates feed intake, digestion, has bactericidal and anti-stress properties with positive effect on animal health and productivity. The experiment revealed a positive effect of feed additive "Activo" on cows’ organism after calving and at the beginning of lactating. The influence of essential oils extracts contained in the feed additive "Activo" on the feed intake and digestion, milk production, protein and fat levels has been studied. There is a systematic dependence on feed intake increasing to milk yield. At the same time, indexes of quality such as fat and protein content were almost stable. According to the experimental results, it is possible to recommend milk producers to use "Activo" as part of cow feed with the aim to improve health and productivity.
