10

Name 2 essential amino acids in pig rations

Methionnine and Lysine

11

Why does this ration be fed to a pig?

In order to fatten them up and finish them for slaughter.

12

Why is soya bean included in this ration?

For its high energy value and high protein content.

13

How is soya bean meal prepared?

Soya bean meal is prepared by dehulling the seed to remove the seed coat.

14

What affect does removing the seed coat have on the ration?

This reduces fibre in the ration.

15

What happens to the seed in order to improve the biological value of the protein

The seed is toasted

16

What is added to ensure some fibre is in the ration?

Soya bean hulls are added to the ration.

17

Name a meal (other than soya bean meal) that is a source of protein?

Rapeseed meal

18

Why should the amount of rapeseed meal be limited in a ration?

Due to the presence of anti-nutritional factors in the rapeseed.

19

What is soya, palm and rape acid oils high in? What do they provide?

High in fat and they provide a good source of energy.

20

What will some pig rations include for energy?

Animal fat

21

What is added to rapeseed meal to help prevent anaemia

Iron

22

What is the benefit of grinding up soya bean seeds and rapeseed seeds in this ration?

Improves digestibility of feeds.

23

Give an example of a grounded up seed

Barley

24

What is barley called when grounded up?

Rolled barley.

25

What does rolling do?

-Breaks the seed coat
-Allowing the ruminant's digestive system to break down contents of the seed.

26

What happens if the seeds are not rolled?

Undigested seeds would be present in the animal dung.

27

Give an example of a pig ration

Kiernan's Prime Finisher Pellets

28

When is a concentrate ration fed to pregnant ewes?

During the final 6-8 weeks of gestation

29

What does concentrate rations help prevent in pregnant ewes?

Twin lamb disease or pregnancy toxaemia.

30

What is steaming up?

The process where a concentrate ration is fed to a pregnant ewe during the final 6-8 weeks of gestation to prevent pregnancy toxaemia or twin lamb disease.
