Artificial Insemination (A.I.)
• One of the early reproductive biotechnologies,
• Permits the use of superior males for breeding purpose,
• Semen from superior males is collected and used to inseminate large number of
females,
• Control of the Venereal diseases,
• Endangered species,
• Issues related with transportation and breeding,

10
Estrus Synchronization
• Bringing the randomly cycling females into one stage of cycle (estrus)
- Prolonging the estrous cycle
- Shortening the estrous cycle
Question: How we can do this?

11
Superovulation
• Protocol used to make the females develop and ovulate more number of oocytes
in mono-ovulatory animals
- GnRH
- FSH
- PMSG
Ques: Can you name the best source of gonadotropic hormones?

12
Embryo Transfer (E.T)
• Females with superior genetics are superovulated and their fertilized ova (in vivo
or in vitro) are transferred to recipients,
• Recipients are genetically less distinguished surrogate mothers.
- Surgical
- Non surgical
21-09-2020
13
In-Vitro Fertilization (IVF)
• Fertilization outside the body i.e., in the laboratory,
- Tissue culture medium
- Modified Tyrode’s
- Kreb’s-Ringer’s solution…..supplemented with sources glucose, lactate,
pyruvate and albumin (Ham F-10) supplemented with blood serum
• In-vitro maturation (IVM)
