Nutrition Vocabulary matching worksheet for learning key terms related to animal nutrition and digestion.

Let’s go step by step to match each definition with the correct word from the word bank.

Word Bank:
- hull
- feed
- diet
- bile
- mastication
- crude protein
- bolus
- thyroxin
- gestation
- enzymes
- reticulum
- omasum

Now, let’s take each definition one at a time:

1. Third compartment of a ruminant animal
→ Ruminants have four stomach compartments: rumen, reticulum, omasum, abomasum.
So third is omasum

2. Proteins which increase the rate of chemical enzymes
Wait — that doesn’t sound right. Actually, *enzymes* are proteins that speed up chemical reactions. The phrase “proteins which increase the rate of chemical enzymes” is confusing — it probably meant “proteins which increase the rate of chemical *reactions*”. That would be enzymes. But note: enzymes themselves ARE the proteins. So this must be referring to enzymes.

But wait — looking again: “Proteins which increase the rate of chemical enzymes” — that might be a typo in the worksheet. It likely means “chemical reactions”. In biology, we say enzymes are catalysts — they speed up reactions. So answer = enzymes

3. Carrying of an embryo or fetus inside a female animal
That’s pregnancy → gestation

4. Second compartment of the stomach of a ruminant animal
Rumen (1st), Reticulum (2nd) → reticulum

5. Outer covering of a seed or fruit
That’s the hull (like on rice or sunflower seeds)

6. Grains and byproducts fed to animals
This is called feed

7. Mixture of food and drink available for animal to provide nutrients
That’s their daily intake → diet

8. Thick yellowish digestive fluid aiding in the digestion of fats
Made by liver, stored in gallbladder → bile

9. Process during which food is crushed by teeth
Chewing → mastication

10. Estimate of the total protein of a feed
In animal nutrition, this is called crude protein (it’s a lab estimate based on nitrogen content)

11. Hormone which regulates metabolic rate
Thyroid hormone → thyroxin

12. Mass of food and saliva that forms in the mouth after thorough chewing
After you chew, it becomes a soft ball called a bolus

Now let’s list them in order as they appear in the worksheet:

Definitions in order:

1. Third compartment of a ruminant animal → omasum
2. Proteins which increase the rate of chemical enzymes → enzymes *(assuming typo — should be “reactions”)*
3. Carrying of an embryo or fetus inside a female animal → gestation
4. Second compartment of the stomach of a ruminant animal → reticulum
5. Outer covering of a seed or fruit → hull
6. Grains and byproducts fed to animals → feed
7. Mixture of food and drink available for animal to provide nutrients → diet
8. Thick yellowish digestive fluid aiding in the digestion of fats → bile
9. Process during which food is crushed by teeth → mastication
10. Estimate of the total protein of a feed → crude protein
11. Hormone which regulates metabolic rate → thyroxin
12. Mass of food and saliva that forms in the mouth after thorough chewing → bolus

All words from the bank are used exactly once? Let’s check:

Used: omasum, enzymes, gestation, reticulum, hull, feed, diet, bile, mastication, crude protein, thyroxin, bolus → 12 words. Word bank has 12 words. Perfect.

Final Answer:

omasum
enzymes
gestation
reticulum
hull
feed
diet
bile
mastication
crude protein
thyroxin
bolus
