50) Biotechnology in animal production: embryo transfer (ET, MOET)

Question 1

MOET

Answer 1

• Multiplex ovulation and embryo transfer
• Increases reproduction rate

Question 2

Advantages of MOET

Answer 2

• Improve reproduction potential
  
  • Selection intensity
  • Breeding value + progeny testing based on:
    
    • Higher no. of females of high genetic value
• Induction of twinning
• Provide higher no. of follicles that ovulate

Question 3

Induction of twinning

Answer 3

• Flushing
• Induction of poly- and superovulation/transfer of two zygotes

Question 4

ET

Answer 4

Embryo transfer

Question 5

Give the process of embryo transfer

Answer 5

1. Careful selection of donor and recipient
2. Cycle synchronisation in the recipient
3. Superovulation in donor animals
4. AI of the superovulated dam
5. Flushing of embryos of the uterus
6. Evaluation of embryos
7. Embryo transfer

Question 6

Methods for embryo transfer

Answer 6

• Catheter
• Surgical
• Laparoscopic
• Endoscopy
