Rezumat

The results of development and enhancement of the existing biotechnological methods of improvement of biological full-value of depreserved sperm of bulls are given in the thesis work. The conditions of efficiency enhancement of the cryopreservation process of bull sperm are determined on the basis of application of positive accelerations of temperature decrease. It is determined that depreserved bull sperms have maximal mobility of 51,7±1,7% during freezing with acceleration of 1730С/min2. In this case the fertilizing ability factor of depreserved bull sperm is equal to 84,0±5,2%.
