Study Notes
Importance of Good Nutrition
- Good nutrition promotes and maintains good health
- It ensures optimal performance in both breeding and physical aspects
- Good nutrition promotes longevity, allowing for a long and healthy life
Disadvantages of Selective Breeding
- No information is provided in the text about the disadvantages of selective breeding

Disadvantages of Selective Breeding
- No information is provided in the text about the disadvantages of selective breeding
Nutrition and Health
- Good nutrition is crucial for promoting and maintaining good health, ensuring optimal performance (both breeding and physical), and promoting longevity.
- A balanced diet provides the energy an animal needs, as well as all other essential nutrients.
- Inadequate nutrition can lead to suboptimal performance, compromised health, and a shorter lifespan.
Importance of Nutrition
- A good breakfast is essential for providing energy and nutrients for the day.
- Skipping breakfast or having a poor diet can lead to energy deficiencies, impacting overall health and performance.
Dangers of Selective Breeding
- Selective breeding can lead to genetic disadvantages, compromising the health and well-being of animals.
- This can result in a range of negative outcomes, including reduced fertility, increased disease susceptibility, and a shorter lifespan.
Importance of Good Nutrition
- Good nutrition is crucial for maintaining optimal health, performance, and longevity in animals
- Adequate nutrition ensures optimal breeding and physical performance
Consequences of Poor Nutrition
- Inadequate or poor quality nutrition can lead to:
- Poor skin and coat condition
- Poor growth rates in young animals
- Poor body confirmation
- Reduced resistance to disease
- Reproductive problems
- Organ and systemic diseases
- Reduced lifespan
Nutrient Requirements
- Nutrient requirement refers to the average amount of a nutrient an animal needs for a specific function
- It is the minimum amount required to prevent deficiency or maintain optimal health
Nutrient Allowance
- Nutrient allowance is the nutrient requirement plus a safety margin
- The safety margin accounts for individual variability in nutrient requirements between animals
Feeding Standards
- A feeding standard is a statement that outlines the amounts of nutrients required by animals
- Feeding standards are usually expressed as quantities of nutrients or a proportion of the diet
- Examples of organizations that produce feeding standards include:
- National Research Council (NRC) in the USA
- Association of American Feed Officials (AAFCO)
Dietary Specialization
- Specialists, who consume a limited number of foods, require less neural resources compared to generalists.
- However, specialists have a much more limited food source, which means they need to forage for longer and over greater areas.
Types of Dietary Specialists
Carnivores
- Meat eaters
- Possess carnassial shears for crushing meat
Herbivores
- Eat vegetation, or specific types of vegetation
- Possess flat, broad molars for chewing plant material
Example of a Specialist
- Koalas are specialists that eat eucalyptus leaves

Dietary Specialization
- Specialists consume a limited number of foods, which requires less neural resources.
- However, this limited diet means they need to forage for longer and over greater areas, resulting in higher energy expenditure.
Types of Dietary Specialization
- Carnivores: meat-eaters, characterized by carnassial shears for crushing and tearing flesh.
- Herbivores: plant-eaters, characterized by flat, broad molars for chewing and grinding vegetation.
- Example: Koalas are herbivores that specialize in eating eucalyptus.
Generalists
- Consume a variety of foods, requiring more neural resources to adapt to different food sources.
- Examples of generalists include omnivores like humans, rats, bears, and pigs.
Specialists vs Generalists
- Specialists consume a limited number of foods, requiring less neural resources but are limited in their food source, forcing them to forage for longer and over greater areas.
Diet Specialization
- Carnivores: meat-eaters with carnassial shears for crushing.
- Herbivores: consume vegetation, with flat broad molars for chewing, e.g., koalas eating eucalyptus.
Generalists
- Consume a variety of foods, e.g., omnivores like humans, rats, bears, and pigs.
- Possess sensory systems that can identify food properties, including toxins and nutrients.
Sensory Systems
- Exteroceptive senses: vision, smell, taste, and touch provide advance information about foods.
- Interoceptive senses: detect food make-up, including nutrients and toxins.
Toxins
- Many plants and some animals produce toxins.
- Many toxins taste bitter, but some do not (idiosyncratic) and can only be detected after eating, leading to illness.
- Regurgitating can help eliminate toxins.
