How can we improve the success rate of fertilisation during artificial insemination in animal husbandry programmes?

The technology is called MOET or Multiple Ovulation Embryo Transfer. During the procedure, a cow is given hormonal treatment so that more than one ovule (6-8 eggs) is produced per cycle. After mating or artificial insemination the embryos at 8-32 celled state are transferred to different surrogate mother cows. The method has been successfully used for cattle, sheep, buffalo etc.

Multiple Ovulation Embryo Transfer Technology (MOET)

It is a programme for herd improvement in animals like cattle, sheep, rabbits, buffaloes, mares, etc.

High milk-yielding breeds of female have been bred with high quality (lean meat with less lipid) meat-yielding bulls to increase herd size in lesser time.

Procedure

i. A cow is administered hormones with FSH-like activity to induce follicular maturation and super-ovulation.

ii. The cow produces 6−8 eggs instead of one egg produced normally.

iii. It is now, either mated with an elite bull or artificial insemination is carried out.

iv. When the fertilised eggs attain 8−32 cells stage, they are non-surgically removed and transferred to a surrogate mother.

v. The genetic mother can now be again super-ovulated.
