  1. REPRODUCTION PHYSIOLOGY OF CATTLE

  2. Principle of Reproduction increasing efficiency of the production decreasing reproduction efficiency

  3. Epididymis

  4. Function Morphology • covered with the tunica vaginalis,a serous tissue • The outer layer of the testes,the tunica albuginea testis • contains germcells(spermatogonia) and nursa cells (Sertolicells) • Leydig (interstitial) cells are found in the parenchyma of the testes between the seminiferous tubules

  5. Temperature Control • Higher temperature causes degeneration of the cells lining the wall of the seminiferous tubules • In cattle ambient temperaturesrange from 5o 21o,the temperature inside the testes will be about 4obelow body temperature(38.6o) • The role of the scrotum and spermatic cord in temperature control of the testes involved drawing • Actual cooling of testes occurs by two mechanisms
