Correction of the immunomorphological development of bulls with bioactive substances, taking into account the fluoride deficiency in the region

The article shows the immunomorphological expediency of complex application to bulls at the beginning of technological cycles of cultivation, rearing and fattening of natural bioactive substances, taking into account local biogeochemical specificity. In this context, scientific, production and laboratory studies were carried out on 30 bulls-analogues, divided into 3 groups. Bulls of experienced groups in 2, 31, 151, 361 at daytime age, permamic was prescribed with polystim or with iodomidol. In animals of the compared groups, the age variability of clinical, physiological, immunological parameters and micromorphology of the thymus gland was determined. In the simulated experiments, it was noted that the combined use of permamic with iodomidol to bulls was accompanied by a more pronounced thyroid-stimulating effect and less pronounced destructive processes in the cerebral zone of the thymus gland than when prescribing permamic with polystim according to the schemes developed by us.
