Multiple Ovulation Embryo Transfer (MOET) technology is a method used in livestock breeding, specifically in cattle, to improve the genetic traits of herds. The process involves the stimulation of a cow to ovulate multiple eggs, which are then fertilized in vitro (in a laboratory) with semen from a selected bull.

The resulting embryos are then transferred to recipient cows who carry the embryos to term. This allows the breeder to produce multiple offspring from a single, high-quality cow or bull, and helps to improve the genetics of the herd more rapidly than traditional breeding methods. MOET is commonly used in dairy and beef cattle breeding programs to increase the rate of genetic improvement and enhance the productivity of the herds.

Drugs used in Multiple Ovulation Embryo Transfer

The drugs used in Multiple Ovulation Embryo Transfer (MOET) technology are typically hormones that are used to stimulate ovulation and regulate the reproductive cycle of the cow. The most common drugs used in MOET include:

• Gonadotropin-releasing hormone (GnRH): A hormone that stimulates the release of follicle-stimulating hormone (FSH) and luteinizing hormone (LH) from the pituitary gland.
• Follicle-stimulating hormone (FSH): A hormone that stimulates the growth of follicles in the ovary, leading to the release of multiple eggs.
• Luteinizing hormone (LH): A hormone that triggers ovulation and the formation of the corpus luteum.
• Progesterone: A hormone that helps to maintain the growth of the follicles and the corpus luteum, which is necessary for the successful transfer of embryos.

• Estrogen: A hormone that helps to regulate the reproductive cycle and maintain the growth of the follicles.

Procedure of Multiple Ovulation Embryo Transfer Technology

The procedure of Multiple Ovulation Embryo Transfer (MOET) technology typically involves the following steps:

• Hormonal stimulation: The cow is given a series of hormones to stimulate the ovaries to produce multiple eggs. This usually involves injections of gonadotropin-releasing hormone (GnRH), follicle-stimulating hormone (FSH), and/or luteinizing hormone (LH).
• Ovarian ultrasound: The growth of the follicles is monitored using ultrasound to determine the timing of ovulation.
• Ovum pickup: The eggs are collected from the ovaries using a procedure known as ovum pickup. This involves the insertion of a special needle through the vagina and into the ovaries to retrieve the eggs.
• In vitro fertilization: The eggs are fertilized in a laboratory using sperm from a selected bull. The resulting embryos are then cultured and monitored to ensure their growth and development.
• Embryo transfer: The embryos are transferred to recipient cows who will carry the embryos to term. This is done using a special instrument that is inserted into the uterus of the recipient cow.

• Pregnancy monitoring: The recipient cows are monitored for pregnancy and the growth of the embryos using ultrasound.
