This chapter describes the role of dietary energy, vitamins, minerals and toxic contaminants on the reproduction of domestic, zoo and wild animals.

This chapter discusses the water requirements, metabolism and quality for domestic, zoo and wild animals. The adaptation and water requirements of herbivores in desert areas are also described.

The roles of proteins, sodium, potassium, chlorine, iron, copper, folic acid, vitamin B12 and vitamin K in the regulation of blood composition and fluid balance and in haemolytic anaemia in domestic, zoo and wild animals are described.

The calcium, phosphorus and vitamin D requirements for proper skeletal development and the diseases that result from the deficiency of these nutrients in domestic, zoo and wild animals are presented.

This chapter discusses the factors that affect feeding behaviour and feed intake of domestic, zoo and wild animals, including diet; feed composition and quality; food palatability, energy, protein and mineral contents; environmental temperature; reproduction and body size.

This chapter discusses the synthesis and metabolism of dietary lipids, lipoproteins, cholesterol and fatty acids in ruminant and non-ruminant domestic, zoo and wild animals.

This chapter discusses the digestion and metabolism of dietary lipids in ruminant and non-ruminant domestic, zoo and wild animals.

The structure, synthesis, function, metabolism and excretion of proteins and amino acids in domestic, zoo and wild animals are described.

The digestive physiology of different nutrient categories and a classification of domestic, zoo and wild animal species based on feeding strategy and digestive tract physiology are presented.
