Development of Methods of Complex Bio-physical and Biological Effect on Productive and Resistance Traits of Young Cattle

Abstract

As a result of the researches the efficiency of low-intensity laser radiation (LILR) usage with the permanent magnetic field (PMF) and immune-correcting preparations for stimulating defensive organism protection sources. It is determined that complex usage of different biological and bio-physical methods of effect increases growth and development speed of young cattle. The best results on performance for the whole research period were obtained from calves of II and III experimental groups from grown up cows and surpassed the control groups at 18,8 and 26,4 %; from first-calve cows - at 18,6 and 27,6 %, correspondingly. So usage of different biological and bio-physical methods of effect promoted normalization of immunoglobulin quantity. Such changes of immune status of calves may be explained by increasing of migration of Т- and В-lymphocytes from thymus and marrow in peripheral ;lymphoid organs with increase of their cooperation effected by LILR with PMF and immune stimulator «Erakond», a complex usage of which promoted calves’ immune status perfection.
