Question 1

A laboratory equipment that is used to incubate samples at a constant temperature over a long period of time.

Answer 1

Water bath

Question 2

used to measure the density of liquids, mostly within small density ranges

Answer 2

Densimeter

Question 3

Protects the sperm cells against possible damage by toxic seminal plasma, as well as providing nutrients and cooling buffers if the semen is to be cooled.

Answer 3

Boar Semen Extender (1 pack 1 L)

Question 4

a catheter similar to a sponge tipped rod catheter is inserted through the vulva into the cervix.

Answer 4

Spiral catheter

Question 5

Extender and Semen Process

Answer 5

1. Put 1L distilled water inside the flask prior to
   collection.
2. Put the flask in the water bath.
3. Measure the temperature of the collected
   boar semen and then set the temperature of
   the water bath similar to the temperature of
   the semen. (In this activity, the collected
   semen measures 32 degrees centigrade,
   therefore, the water bath was also set in
   similar temperature).
4. While waiting for the water to reach the
   set temperature, pour 1 sachet of Boar
   Semen Extender inside the flask and
   dissolve.

Question 6

Semen Fraction

Answer 6

Prepuce, Tapioca gel, Sperm rich

Question 7

Semen fraction that is first to come out, must be spilled. Do not collect.

Answer 7

Prepuce

Question 8

Semen fraction collected using filter to separate
tapioca from sperm rich and
other foreign materials.

Answer 8

Tapioca gel

Question 9

Semen fraction contains the sperm cells. The fraction that must be collected.

Answer 9

Sperm rich

Question 10

Boar Semen Normal Temperature

Answer 10

36-38 degrees centigrade

Question 11

Boar Semen Normal Density

Answer 11

200-300
million per mL

Question 12

How to measure sperm density

Answer 12

Pour 2 mL semen and 10 mL Boar
Extender solution in the densimeter
bottle. Secure the lid.
Put inside the densimeter machine
and wait until it shows the semen
density.

Question 13

Sperm dilution

Answer 13

1. When pouring the semen to the container with
   the water (same temperature), pour slowly to
   avoid sperm shock.
2. Mix the semen to the water.
3. In this activity, a total of 1200 mL dilution is
   produced.
4. Pour the diluted semen to the squeeze bottle for
   packaging.

Question 14

Semen collection for senior boar

Answer 14

2x a week

Question 15

Semen collection for junior boar

Answer 15

once a week

Question 16

Sow is inseminated

Answer 16

3x per cycle

Question 17

Swine Artificial
Insemination Process

Answer 17

1. Insert catheter up to the sow cervix rotating in 45 degrees counterclockwise.
2. Insert the squeeze bottle to the catheter *Do not insert squeeze bottle until the
   catheter is locked inside the cervix.
3. Squeeze the semen to the catheter. Cover the lid. *Only 1 bottle is required for sow
   in standing heat; otherwise, use 2 bottles.
4. Leave the catheter for 15-30 minutes or longer to ensure that all the semen will enter
   the reproductive tract and there is no backflow.
5. Once done, remove the catheter in clockwise direction.
