Multiple ovulation and embryo transfer (MOET) Which statements about MOET in livestock breeding are correct?

Difficulty: Medium

Correct Answer: All of the above

Explanation:

Introduction / Context:MOET is a reproductive technology used in cattle and other species to amplify the number of offspring from genetically superior animals, accelerating genetic gain in breeding programs.

Given Data / Assumptions:

  • Superovulation yields multiple embryos from elite females.
  • Embryos can be flushed, evaluated, and transferred to recipient females.
  • Genetic evaluation relies on performance and progeny data.

Concept / Approach:By multiplying embryos from top sires and dams, MOET expands the dataset for genetic evaluations, enables earlier and more accurate selection, and spreads elite genetics quickly across herds.

Step-by-Step Solution:

Use exogenous hormones to induce multiple ovulations in elite donors.Fertilise (AI or natural) and non-surgically recover embryos.Transfer embryos to synchronized recipients to produce many half-sibs.Leverage the larger progeny groups for robust progeny testing of both sires and dams.

Verification / Alternative check:Breeding program simulations and field data show increased selection intensity and shortened generation intervals using MOET.

Why Other Options Are Wrong:

  • Each single statement (a–c) is correct but incomplete; MOET delivers all these benefits.
  • “None” contradicts well-documented outcomes.

Common Pitfalls:Poor synchronization of recipients, inadequate donor response to hormones, and insufficient genetic evaluation frameworks can diminish MOET benefits.

Final Answer:All of the above
