Studies On Preservation of Ram Semen By Freezing And Other Methods

improve survival and fertilizing ability of semen preserved by the different methods. This work was planed to improveal survival and fertilizing ability of semen preserved by the different methods. Improvement of frozen and cooled ram spermatozoa was tried by supplementing semen with prostaglandin F. Cholesterol and some trace minerals after removal of semsinal plasma by centrifugation. Trials to improve survival rate of spermatozoa during preservation of semen at room temperature by activation of semen using different extenders have also been attempted.
