Acetic

6

What is the mineral in higher content in beef cattle ash?

K, P, Mo, Zn, Ca

Ca - Calcium

7

What is the primary nutrient component in livestock feeds?

Carbohydrates

Composed of: C, H, O

8

What is a monosaccharide? What are two important monosaccharides we often refer to?

1 sugar molecule

**Fructose and Glucose
(these are hexose monosaccharides)

Fructose and glucose together make Sucrose

9

What is a disaccharide? Some examples?

2 sugar molecules

Lactose, Maltose, Sucrose

10

What is a polysaccharide and some examples?

Multiple sugar molecules

Cellulose, glycogen, starch, gums, hemicellulose

11

Where is protein found in the highest concentration?

In all living organisms (after water)

12

What are some functions of proteins?

Protecting the body (hair, skin)
Food digestion (enzymes)
Stimulating growth (hormones)
Immune reactions (immunoglobulins)

13

What are the building blocks of proteins?

Amino acids

Protein = a long chain of amino acids

14

What are the essential amino acids?

Arginine, Histidine, Isoleucine, Leucine, Lysine, Methionine, Phenylalanine, Threonine, Tryptophan, Valine, Taurine (cats)

15

What amino acids are low in cereals and thus more likely for those animals eating them to be deficient in?

Lysine
Methionine
Tryptophan

16

T/F: If an AA is required to synthesize a protein is not available, that protein will not be synthesized

TRUE

17

Organic compounds insoluble in water but soluble in organic solvent, are _________

lipids

Found in plants and animals

18

What is the main role of lipids?

Concentrated form of stored energy

19

What constitutes a saturated fatty acid?

When all bonds in the carbon are taken up by hydrogen (all the carbons are saturated)

20

What are five common unsaturated fatty acids?

Palmitoleic
Oleic
Linoleic
Linolenic
Arachidonic

21

What are essential fatty acids?

FA that animals require but are NOT able to synthesize

Ex: linoleic and linolenic

22

What percent of the monogastric animals diet is composed of essential fatty acids?

1%

These are imporant to the lipid protein structure of the cell membrane and prostaglandin

23

Scaly skin, necrosis of the tail, and poor feathering are all examples of what nutrient deficiency?

Lipids/Essential fatty acids

More frequent in poultry

Skeleton

*ash content = mineral content (non specific)

27

What vitamins are fat soluble?

Water = C, B1, B2, B6, B12

Fat = A, D, E, K

30

Liver

(smaller amts are stored in the kidneys and spleen)
