INFLUENCE OF THE NEW VITAMIN-MINERAL PREMIX TO THE BODY OF CATTLE
The vitamin-mineral premix for cattle, produced by a separate wet granulation technology to retain the activity of vitamins and minerals was chosen as the object of investigation. Components of the vitamin-mineral premix were selected according to the needs of animals, bioavailability and stability of substances. The effect of the premix to animals was investigated. We controlled the growth dynamics of body mass of different age animals and determined the impact of the premix to change some of the biochemical and immunological characteristics of blood. The experiment involved the animals with an average body weight 60.20 kg and 92.33 kg. Premix positive impact on the cattle weight dynamics was observed in the case of adding it to the diet of animals, body weight that exceeded 80.00 kg. The results obtained revealed the age groups of animals which were most susceptible to the effects of premix and the optimal scheme of the premix application.
