Animal Biotechnology definition

An improved term for superovulation is..

What exactly are some good reasons for embryo transfer?

Increase the quantity of offspring from selected females

enhance offspring from chosen guys

import/export of genetics

analysis

Why would embryo transfer be an edge for indigenous weight to disease from recipients?

Embryos created to indigenous cattle will obtain the resistance from colostrum of this indigenous cow

How is embryo transfer utilized in genetic evaluation of bulls?

Progeny screening and used to identify recessive faculties

Which continents represent the majority which use embryo transfer?

Just why is it vital that you superovulate a cow before the principal follicle appears?

The dominant hair follicle will cause one other follicles in the cohort to regress. If superovulated at the beginning of the follicular wave, before the appearance for the principal hair follicle, small hair follicles in cohort will likely be rescued

Whenever superovulated with FSH, this may trigger a _____ impact. Ovulation associated with the cohort don't happen until P4 levels reduce resulting in the release of several follicles.

Injections timed during an all-natural cycle or perhaps the cycle is managed by ___

Controlled Intravaginal Drug Releasing product

What is the traditional superovulation protocol in cows?

Day 9-12(4 times): FSH injections

Inject PGF time 12

AI 24 hours after PGF

Gather embryos 6-8 days after very first AI

What is the superovulation protocol with a CIDR?

Insert CIDR time 1 of period

Day 4-7: FSH shots

Day7: inject PGF and remove CIDR

Day 8: Expect estrus and AI

Day 15: compile embryos

Which method of collection is normally found in cattle? non-surgical or medical?

non-surgical collection (flushing)

Whenever is embryo collection typically in cattle?

What type of option would be used whenever flushing for embryos?

Exactly what stage will the embryos be upon collection?

What's the typical wide range of viable embryos gathered?

Where will the embryo be deposited inside individual cow?

uterine horn, exact same part since the CL

It is important to perhaps not manipulate the uterine horn an excessive amount of during transfer because ___

It'll cause the launch of PGs which will result in the CL to regress aborting the embryo

Synchrony between donor and recipient is __

What is the expected pregnancy price in embryo transfer?

Exactly what elements affect the pregnancy rate in embryo transfer?

individual administration: "quality" age, virility, condition

Exactly what are some programs of in vitro embryo production?

• study
• help various other embryo technologies: cloning, transgenic creatures, biomedical programs
• assisted reproduction in domestic creatures: production of animals

Exactly what are the 3 components of in vitro embryo production?

• In Vitro Oocyte Maturation (IVM)
• In Vitro Fertilization (IVF)
• In Vitro Culture (IVC)

Immature oocyte cumulus cellular complexes from abattoir product (unknown origin) or aspirated from selected people by ultrasound directed aspiration. Oocyte cumulus cellular buildings invest tissue tradition method, plus serum and gonadotropins. Incubation 22-24 hours. Nuclear maturation to metaphase II phase of oocyte. Cumulus cellular growth. Creation of intercellular matrix and GAGs

Abattoir dervived could be the term useful for ___

Oocytes accumulated from random ovaries from as yet not known resources, often in a slaughter house

If a follicle is just too big, so what does this do in order to the effiency of aspiration?

Cumulus cells all over oocyte are crucial for ____

Mixing of mature oocyte expanded cumulus cell complexes with sperm

How will be the motile semen separated?

Percoll separation(thickness gradient product) or swim up strategy

Exactly what induces capacitation of sperm in IVF?

Glycosaminoglycan

Polysaccharides with a high molecular body weight containing amino sugars and often develop complexes with proteins

GAGs saturated in _____ at ovulation also in broadened CC matrix
