This chapter discussed the different methods of estimating the net energy and protein requirements of rabbits during the different stages of production particularly during the lactation and pregnancy period for female rabbits. The effects of protein and energy intake and metabolism on the...

This chapter discussed the different variables in the environment that affects the nutrition of rabbits. Among these variables are temperature, humidity, light, altitude, small and noise. In this chapter the variables temperature and humidity were given emphasis.

A review on the importance of trace elements, vitamins, major minerals, carbohydrates, energy and proteins in supplying the nutrient requirements in cattle was presented as well as on how deficiences or excess may result into metabolic diseases that indirectly or directly affects profitability and...

This chapter discusses some of the potential pitfalls when designing and characterizing experimental diets and ideas on how to limit their impact on the experiment. It will also touch on the importance of recording such design information. Highlights of this chapter focus on the following:...

Globally, livestock contributes 40% to agricultural gross domestic product (GDP), employs more than 1 billion people and creates livelihoods for more than 1 billion poor. From a nutritional standpoint, livestock contributes about 30% of the protein in human diets globally and more than 50% in...

This chapter reviews the different aspects of nutrition and the utilization of dietary nutrients by the camel. It examines the anatomy and physiology of the camel's digestive system, particularly the forestomach, as well as nitrogen economy and methane emission in camels. Special attention is paid...

The purpose of this chapter is to illustrate some of the main concepts and give examples of useful approaches to understanding efficiency in relation to growth. The ultimate limitations to the drive for efficiency include not only the obvious laws of thermodynamics and of biochemistry, but also the ...

This chapter covers the energy and protein requirements of rabbits as well as their metabolism. The energy units (gross, digestible, net and metabolizable energy) and the methods used for estimating energy requirement are presented. The aspects of energy metabolism related to vital and productive...

This chapter covers the different units used for feed evaluation such as energy (digestible, metabolizable and net), crude protein and amino acids and fibre (neutral detergent fibre, acid detergent fibre, acid detergent lignin, crude fibre and soluble fibre). Moreover, the methodology of feed...

The mathematical calculation and alternative methods for determining nutrient availability and nutrient value of animal feeds are described.
