      Up to puberty primordial follicle will be converted upto tertiary and then will undergo atresia, but at puberty when GnRH changes into pulsatile fashion then preantral follicles will recruited for the further processes. Is this right sir?

    • @GNPSir

      @@sunadbalgi1669 What is known till now Not all primordial follicles are converted to tertiary follicles and then undergo atresia. The conversion of primordial follicles into tertiary, secondary, preantral, and antral follicles continues throughout life yet after puberty the antral follicles are selected to grow under a follicular wave in cattle due to the establishment of the relationship between the hypothalamus-pituitary gonadal axis and thus the antral follicles enter sequential growth under pituitary hormone influence. Before puberty, the primordial follicle growth is dependent on intraovarian factors and maybe they enter atresia at a faster rate.

    It is excellent lecture. If etiology is added why some animals have 1, 2,3 follicular waves cycle and its effect on length of oestrus cycle. It would have been better

    Can we convert or manipulate follicular waves? (Convert 2 follicular waves into 3 follicular waves)

    • @GNPSir
      @GNPSir  2 ปีที่แล้ว

      Boer et al., 2011 J Dairy Sci proposed a model through which the 3-wave cycle could possibly be changed to -2 wave cycle in dairy cows however, this seems extremely difficult practically as it is really difficult to control so many factors proposed in this study.

      Dear Pawan
      Prolonged bleeding can be because of ovarian cysts, tumors or tumor of pituitary. I would suggest hCG injection like Pubergen 22 IU per Kg IM for 3 days. Also check for TVT if TVT is present vincristine is advisable. If you don't want pups hysterectomy can be a better option in ovarian tumors
