Study on anatomy and histological structure of porcupine ovary.

In order to understand the female porcupine procreating physiology and provide the foundation for studying on the procreating technology of the manpower such as the judgement of oestrus,the technique of urging oestrus,the artificial insemination,the embryo transplant,the fecundation outside the body etc,this experiment took porcupine ovary as the object of study,observed the porcupine female gonad's dissection and organizational structure,researched the porcupine female gonad.The result indicated that the porcupine ovary outward appearance assumes the cream color,the compressed ellipse,its vertical diameter is 0.92-1.03 cm,the transverse diameter 0.63-0.72 cm,thickness 0.330.37 cm,weight 0.18-0.22 g.It's obviously observed that the 3-6 graafian follicles were growing in ovary surface under the microscope,the entire ovary volume increased.When the graafian follicle become maturity,the graafian follicle highlights in the ovary surface and presents the shape of half spherical.The gonad of the female porcupine had not obvious seasonal change,but the ovary had corresponding change in the cycle of oestrus.
