animal science

Why do we study nutrition in animals?

To understand differences in digestive tracts and carbohydrate digestion.

What are the two classifications of animal feeds?

Concentrates and Roughages.

What is the primary characteristic of concentrates?

High in energy, low in fiber, and highly digestible.

What are carbonaceous feeds?

Feeds that are low in protein, such as cereal grains and molasses.

What are nitrogenous feeds?

Feeds that are high in protein, like oil meals and fish meals.

What is the main energy source for animals?

Carbohydrates.

What happens to excess protein consumed by animals?

It is either stored as fat or excreted.

What is the function of lipids in animal nutrition?

Provide high energy, insulation, and protection for internal organs.

What are the two types of vitamins based on solubility?

Fat-soluble and water-soluble vitamins.

What is the primary role of minerals in animal nutrition?

To act as components of hormones and enzymes and maintain osmotic pressure.

What does NPN stand for?

Non-protein nitrogen.

How is protein content determined in feedstuffs?

By determining nitrogen content and multiplying by 6.25.

Why is fiber important in ruminant animal diets?

It aids in fermentation and digestion in the rumen.

What nutrient is most crucial for survival in animals?

Water.

What is digestion defined as?

Preparing food for absorption in the gut.

Which part of the digestive tract is the main site for nutrient absorption?

The small intestine.

What is the purpose of pelleted rations?

To dry down wet feed for storage and prevent mold.

What is the main source of energy in animal diets?

Carbohydrates.

How do plants make carbohydrates?

Through the process of photosynthesis.

What type of fiber is digested only by rumen microbes?

Cellulose.

What are the four compartments of a ruminant's stomach?

Reticulum, Rumen, Omasum, Abomasum.

What is the primary carbohydrate that cattle utilize for energy?

Starch.

What nutrient will cause death if lost above 10-14% of body water?

Water.

Which vitamin is essential for blood clotting?

Vitamin K.

What condition is caused by a deficiency of iodine?

Goiter.

What is the role of bile in the digestive process?

Aids in fat digestion.

What is the function of enzymes in digestion?

To increase the speed of chemical reactions in the digestive tract.

What kind of digestive system do horses have?

Specialized monogastric with hindgut fermentation.

Why do cattle often bloat on the left side?

Because the rumen is located on the left side.

Which feed additive promotes growth and increases feed efficiency?

Growth stimulants.

What is Total Digestible Nutrients (TDN)?

A measure of the energy content of feedstuff.

What is a common source of non-protein nitrogen (NPN)?

Urea

How do animals primarily get vitamins?

Animals primarily obtain vitamins through their diet.

What is the specific role of fiber in non-ruminant diets?

Fiber aids in maintaining gut health and proper digestion.

What type of carbohydrate is resistant to fermentation?

Lignin

What is the main byproduct of carbohydrate fermentation in the rumen?

Volatile fatty acids

What impact does processing have on feedstuffs?

enhance digestibility and nutrient availability in feedstuffs.

What is the significance of water in metabolic reactions?

Water acts as a solvent and is essential for metabolic reactions in animals.

What nutrient deficiency can lead to poor bone development in animals?

calcium or phosphorus

Which type of feed is often used to increase protein levels in livestock rations?

Oil meals

How does energy level in a feed affect animal growth?

Higher energy levels in feeds = faster weight gain

What is the role of carbohydrates in animal diets?

provide energy and support metabolic processes.

What are volatile fatty acids (VFAs)?

VFAs are products of carbohydrate fermentation in the rumen and used as an energy source by ruminants.

Why is water considered a nutrient?

It's essential for maintaining body temperature, transporting nutrients, and facilitating metabolic reactions.

What effect does high protein have on livestock diet formulation?

improve growth rates and reduce feeding costs if balanced correctly.

What is the importance of vitamins for animals?

they are crucial for metabolic processes, immunity, and overall health in animals.

How does the body store EXCESS energy in animals?

Excess energy is primarily stored as fat in adipose tissues.

What are the main functions of protein in animal nutrition?

Protein is essential for tissue growth, repair, and the production of enzymes and hormones.

Which mineral is critical for oxygen transport in blood?

Iron is critical for the formation of hemoglobin, which transports oxygen in red blood cells.

What are byproducts, and how are they used in animal nutrition?

secondary products from food processing used in animal feed
