EFFECT OF FOLLICLE SIZE ON NUMBER AND QUALITY OF OOCYTES IN BOVINES

Abstract

The 891 follicles from 166 bovine ovaries were categorized as per their size (<4mm, 4 to 8mm and> 8mm)
to observe the effect of the follicle size on oocyte number and quality. The number of oocytes recovered from
< 4mm sized follicles was significantly higher (p < 0.01 ), when compared tb the recovery rate in 4 to 8mm and
> 8mm category follicles (50.16, 40.62 and 9.2 per cent). Irrespective of the size of the follicle, the yield of grade
I oocytes was significantly higher (p < 0.01) when compared to other grades. It was also observed that the quality
of oocyte and follicle size had an interactive effect
