How this cutie pie look...

rachellimjc — 2020-08-31 14:10:19 UTC

Baa baa black sheep, have you any wOOL? Yes sir, yes sir, THREE BAGS FULL~

How this cotton ball sound...

rachellimjc — 2020-08-31 14:13:13 UTC

It goes baaaaa~

IVP?

2000tet — 2020-08-31 15:26:44 UTC

In-vitro production of embryos (IVP) is the procedure for the production of embryos. Which consists of three stages - IVM (in-vitro maturation), IVF/ICSI (in-vitro fertilization/intracytoplasmic sperm injection) and IVC (in-vitro embryo culture).

Ram

rachellimjc — 2020-08-31 16:13:10 UTC

Ram is the male sheep!

Ewe

rachellimjc — 2020-08-31 16:18:49 UTC

Ewe is the female sheep!

Lamb

rachellimjc — 2020-08-31 16:21:24 UTC

Lamb are young sheep below 1 year old!

NOP, sheep isn't a goat.

rachellimjc — 2020-08-31 16:52:38 UTC

Goat

rachellimjc — 2020-08-31 16:55:39 UTC

- slender body
- independent
- rear on back legs
-tails pointing skywards

FuN fAcTs: Sheep has rectangular pupils

rachellimjc — 2020-08-31 16:58:13 UTC

Rectangular pupils gives them amazing peripheral vision of 270- 360 degree which is a great asset for a prey animal!

Where do the oocytes come from?

2000tet — 2020-08-31 17:01:13 UTC

The oocytes used for the fertilization are normally harvested from slaughterhouse animals, or from superovulated live animals. Proceeding to the culture of the eggs in a certain condition (temperature, humidity, and culture medium)

Sheep

rachellimjc — 2020-08-31 17:03:50 UTC

- tubbier body
-flocks
-attacks head on
- tail pointing downward

After maturation......

2000tet — 2020-08-31 17:14:22 UTC

Upon the maturation of the oocytes, they are proceeded with IVF or ICSI for fertilization.

Self opinions

Firstly, the effect of these approach cause no harm to the animal as oocytes are released continuously like human. Therefore, this technique is just to obtain manually from the animal and perform the IVF. Furthermore, this method help the animal reproduce easily especially certain species having fertilization difficulties.

Differences between

karfee1108 — 2020-09-01 12:58:39 UTC

IVF
- Natural selection of sperm
- Higher chances of failure
- For fertile/infertile sheep

IVF and ICSI

karfee1108 — 2020-09-01 13:36:41 UTC

ICSI
- 1 sperm is chosen to fertilise the eggs
- Higher chances of success rate
- Usually used for infertile sheep

More offspring produced

chiaboonjiat2000 — 2020-09-01 16:17:44 UTC

The infertile sheep can be fertilized through lab-based ARTs such as IVF & ICSI

Improve the income and livelihood of the farmers

chiaboonjiat2000 — 2020-09-01 16:31:03 UTC

Generate more income

chiaboonjiat2000 — 2020-09-01 16:32:02 UTC

After finishing the cutting...

Please leave me alone...

Flow of IVF vs ICSI?

karfee1108 — 2020-09-01 17:19:53 UTC

chiaboonjiat2000 — 2020-09-01 17:27:07 UTC

Wow see a cutie pie is seeing our padlet!

Will it affect the environment???

csianghau2000 — 2020-09-01 17:32:38 UTC

From my opinion, this approach will not affect the environment.
The more the better!!!!!
Sheep are one of our food source, therefore having a large population can overcome the demand of market needs.

A good BGM is a must when reading this baa baa padlet:

Baa! Hello everyone! Welcome to sheep world~🐏

chiaboonjiat2000 — 2020-09-07 12:12:02 UTC

Baa (Hello)...Baa (Hello)...
Please enjoy to see the Baa Baa Sheep information here. This padlet contains some basic information about sheep (not a goat!) and the Assisted Reproductive Technologies (ARTs) of them.
If you don't like many words, at least can see the pictures.
Hope our padlet can make your day !❀

Opps forgot to introduce ourselves hehe...
