Reproductive Technologies Flashcards
What are reproductive technologies used for ?
To regulate and monitor breeding
What are the main ways of identifying ovulation in animals ?
Detecting body temperature increases
Detecting decreases in PH of the vulva
Identifying hormone changes
Observing behavioural changes
Name some examples of reproductive technologies
Artificial insemination
In - vitro fertilization (IVF)
Embryo transfer
Sperm sexing
What is Artificial Insemination ?
A process where sperm is collected from the male with desirable traits and is then used to manually inseminate the female.
What is In- Vitro Fertilization (IVF) ?
A process where an embryo is created in the lab from sperm and eggs from parents with diserable traits. The embryo can be implanted into the mother’s womb or an unrelated female.
What is Embryo Transfer?
Where super ovulation is used to increase the number of ova in the donor who is inseminated repeatedly over a few days. The donors uterus is flushed before the eggs can implant and the eggs are then collected. The eggs are the analysed and the best are transferred to the uterus of a recipient.
What is Sperm Sexing ?
A process where spermatozoa carrying male and female genes can be separated and used in IVF to influence the proportions of male and female offspring produced.
This is commercially important in milk and meat production. Females for milk males for meat.
What are the two affects that hormone therapy can have on ovulation?
Superovulation and Synchronisation
What is Super Ovulation?
A process to increase the number of eggs the female produces with each oestrous cycle.
What is Synchronisation?
A process to regulate the oestrous cycle of a group of animals. This makes offspring due at a similar time.
Commonly used alongside artificial insemination
