ABSTRACT

In order to evaluate the recovery rate of local abattoirs oocyte the metropolitan region of Teresina-PI.Ovaries were used 72 36 pubescent sheep without defined breed (SRD) .The collected ovaries were transportedto the laboratory in thermos physiological saline (0.9% NaCl) heated at 35 ° C plus 30 ug / ml sulphategentamicin in a maximum of two (2) hours, the follicular aspiration needle attached syringe was subsequentlyperformed, the aspirated pellet was deposited on heated Petri dishes previously in hot plate to 37 ° C for theidentification and classification of oocitárias structures. 52 were recovered oocyte cumulus cells and the ewerecovery rate was 1.4. Therefore the low recovery rate can be the result of the female body condition, foodsupply, breeding age and age of the animal.
