In this regard, superior buck selection seems to be very important and alternative approach to boast up the production potential. Therefore, during selection of breeding buck special attention should be given on age, body weight, soundness of the sexual organ especially testis and quality of semen. The testicular parenchyma is composed of seminiferous tubules (from which spermatozoa is formed) and leydig cells or interstitial cells.
