Study Notes
Introduction to Animal Nutrition
- Nutrient refers to components in animal feed that support health and growth, including proteins, minerals, and energy.
- Nutritive value is the ability of feed to provide necessary energy and nutrients efficiently.
Photosynthesis and Energy
- Carbohydrate is the main product of photosynthesis, supplying energy to plants.
Rations and Feed Types
- Ration indicates the specific nutrient intake for a single animal over 24 hours.
- Energy feeds contain at least 20% protein or high energy with low fiber.
- Dry forages and roughages generally contain 18% fiber and provide high energy.
Supplements and Balanced Rations
- Supplements are feeds or mixtures that enhance the nutritional quality of a base feed.
- A balanced ration meets the distinct nutritional needs of an animal species and class.
Metabolic Water and Nutrient Catabolism
- Under typical conditions, metabolic water can be produced from lipids, carbohydrates, and proteins; minerals do not contribute.
Feed Additives and Nutrients
- Additives include antibiotics, food colorings, and flavors to enhance feed properties.
- Not all substances are classified as nutrients; for example, limestone is not considered a nutrient.
Organic Nutrients and Forages
- Organic nutrients include vitamins, nucleic acids, and lipids; minerals are inorganic.
- Corn grains are not classified as forage; they do not qualify under typical feed classifications.
Animal Nutrition Processes
- Key processes in animal nutrition focus on nutrient metabolism, digestion, and waste excretion, while appetite improvement is less critical.
Water Requirements
- In cold water, increased water requirements coincide with decreased feed intake.
- Feedstuffs that absorb high amounts of water can lower drinking water needs in animals.
Nutrition Process and Effects of Water Intake
- Excretion is the final stage of the nutrition process.
- Excessive water intake can reduce feed consumption, harm animals, or cause bloating.
Factors Affecting Feed Consumption
- Factors such as pregnancy, cold weather, and unavailability of drinking water may cause animals to eat less.
- Birds have lower water needs due to excreting uric acid in a solid form compared to mammals.
Essential Nutrients
- Essential nutrients include fat-soluble vitamins, minerals, and polyunsaturated fatty acids.
- Carbohydrates contribute to energy but are not structural; vitamins are necessary for enzymatic functions.
Indispensable Nutrients
- Indispensable nutrients are those that animals cannot synthesize and must be obtained from their diet.
