Study Notes
Overview of Female Anatomy & Reproductive Techniques
- Topics include Clinical Anatomy, Female Sterilization, Breeding Soundness Examination, and Artificial Insemination.
- Advanced reproductive technologies include IVF, Embryo Transfer (ET), and cloning techniques.
Female Sterilization
Surgical Methods
- Ovariohysterectomy: Complete removal of ovaries and uterus.
- Ovariectomy: Removal of ovaries only.
- Ovary-Sparing Spey/Hysterectomy: Ovaries preserved while the uterus is removed.
- Tubal Ligation: Surgical procedure to block fallopian tubes.
Hormone-Preserving Sterilization
- Focuses on methods that maintain hormonal function post-sterilization.
Chemical Methods
-
Deslorelin Implant:
- Available in 4.7mg (6 months) and 9.6mg (12 months).
- Duration of effect varies, causes receptor downregulation, suppressing FSH and LH.
- Contraindicated in bitches, used in queens with reduced flare-up effects.
-
Melatonin Implant (Queens):
- Options include 10mg and 15mg implants, safe for reproduction.
- Effects are variable and less disruptive to hormonal balance.
-
Other methods include kisspeptin, GnRH vaccines, and fibrotic agents.
Breeding Soundness Examination
- Consists of a thorough history and physical examination, emphasizing the reproductive system.
- Key areas of focus:
- Vulvar confirmation and vaginal examination.
- Assessment of cervix, uterus, and ovaries.
- Laboratory tests to evaluate reproductive health.
Artificial Insemination Techniques
Transvaginal Insemination
- Catheter inserted into cranial vagina.
- Applicable for fresh and chilled semen.
Trans-Cervical Intrauterine Insemination
- Endoscope visualizes cervix; catheter passed into the uterus.
- Suitable for fresh, chilled, or frozen semen.
Surgical Intrauterine Insemination
- Involves midline laparotomy to access the uterus; catheter inserted into each uterine horn.
- Requires anesthesia; can utilize fresh, chilled, or frozen semen.
Embryo Transfer (ET)
- Selection of synchronized and superovulated donor.
- Embryos are collected via flushing prior to attachment, assessed for quality.
- High-quality embryos are transferred to synchronized recipient cows, using either fresh or frozen/thawed embryos.
- Transfer methods include surgical or transcervical techniques.
In Vitro Fertilization (IVF)
- Involves fertilizing matured oocytes with sperm cells outside the body (in vitro).
