Abstract

On  the first stage  experiments  are conducted  by the aim of establishment  on  how  many higher the real indexes of fresh sperm and dilute protective environments after moving away of cellular debris, extraneous cages and dead cages. On the second stage, comparison of basic physiological indexes of the fertilization faction got from deconservation sperm and compared to the corresponding indexes of з sperm was conducted, that was not subject to the special cleansing procedure. Difference  between research and control groups, in relation to survivability of sperm and index of absolute survivability of sperm was statistically reliable (Р < 0,001), as for fresh sperm so for sperm, that carried freezing and  thawing in liquid nitrogen. Faction of sperm, that has impregnating ability potentially, as fresh sperm so that was subject to freezing and thawing substantially differ in the row of biological indexes of sperm,  that creates  the necessity  of introduction of new additional descriptions for the analysis of sperm. Index  of  survivability  of  sperm, that potentially has impregnating ability at  deconservation  sperm rose on three hours or on a 32,8 percent’s . Index of absolute survivability of sperm, that potentially has impregnating ability rose on 8,19 conditional units. The modernized method of estimation of quality of sperm of bulls is offered. It is  set that  treatment of sperm with the  use of gradients of closeness exceeds the indexes of activity, to  survivability and absolute survivability as at  fresh standards of sperm so at  deconservation standards of sperm, that gives an opportunity more objectively  to describe quality of sperm. Results over of researches of biological quality of  sperm of bulls of meat blackly-pied and red-pied suckling breed are brought depending on the method of treatment of tests. Additional  descriptions of analysis sperm are entered, they can become the major criteria of estimation of full value and impregnating ability.
