COW OOCYTE PICK-UP BY THE TRANSVAGINAL PUNCTURE OF FOLLICLES
Abstract
The results of studying the influence of some factors on the efficiency of the cattle pick-up are presented in the article. It is established that the level of recoverability of the oocyte-cumulus complexes from the number of punctured follicles is 68.7%. The yield of oocytes per one aspiration is 2.7, including per one positive aspiration for extraction – 3.3. Most acceptable for aspiration is the 17G dia needle regardless of the vacuum level. The greatest number of aspirated follicles (6.2 and 8.0) and picked-up oocytes (4.0 to 5.5) is observed when for simulation the follicle-stimulating Pluset hormone is used at a dose of 750 I. E. with or without the use of the progestagen drug Crestar during the stimulation process.
