Assessment of the clinical and physiological state and quality of meat in bull calves under the conditions of an eco-adaptive content system

The paper shows the physiological feasibility of complex assignment of bioactive substances of natural nature contained in an eco-adaptive habitat to bulls. In this regard, a series of scientific, production and laboratory studies was conducted using 3 groups of similar bulls with 10 heads each. Experimental animals were kept from 2 to 150 days according to adaptive, and then up to 540 days of life (duration of research) according to industrial technologies. Bulls of group 1 were control. Animals of groups 2 and 3 were treated with trepel with «Polystim» and iodomidol with selenopyran, respectively, taking into account the local agro-soil specificity of the region. It is proved that the experimental bulls had a normal clinical and physiological status. Samples of their meat were characterized by almost identical organoleptic, biochemical, microbiological and spectrometric parameters. The data obtained indicate that the tested bioactive substances are environmentally harmless to the body and that meat carcasses are indifferent to them.
