_______ is commonly used in animals as a compact source of energy.
Energy. The energy yield of a source of feed (such as natural pasture) can be estimated from its dry-matter weight per unit area. Module 6 discusses the various methods used to estimate biomass or dry-matter weight under rangeland conditions. 2. Define nuclear energy. ______________________________________________________________. _____________________________________________________________. 3. The sun is a renewable energy source. List examples of the possible natural uses of the sun. Energy is the capacity to do work. The unit of energy most often used in this country is the Btu (British Thermal Unit). The unit measure of electricity is the kilowatt hour (kWh), which is about equivalent to 3,412 Btu's. The most common disaccharide is sucrose. It is composed of glucose and fructose. Sucrose is commonly used by plants to transport sugar from one part of the plant to another. Disaccharides are also oligosaccharides. An oligosaccharide consists of a small number of monosaccaharide units (from about two to ten) joined together. Glucose is the most common simple carbohydrate.

They are produced during photosynthesis and are the main sources of energy for plants and animals. The term carbohydrate is used when referring to a saccharide or sugar and its derivatives. Carbohydrates can be simple sugars or monosaccharides, double sugars or disaccharides, composed of a few sugars or oligosaccharides, or composed of many sugars or polysaccharides. During the descriptive phase of livestock systems research, data obtained from informal surveys, secondary data sources and other diagnostic studies can be used to determine the need for further diagnostic research on animal nutrition issues. Introduction [edit]. Carbohydrates are one of the fundamental classes of macromolecules found in biology. Carbohydrates are commonly found in most organisms, and play important roles in organism structure, and are a primary energy source for animals and plants. Most carbohydrates are sugars or composed mainly of sugars. This part of the module focuses on the methods and techniques used in estimating the supply of different nutrients to animals in particular situations or systems, in relation to their need for these nutrients. It starts with a general section on estimating the main feed components. Compound Carbohydrates (Disaccharides) [edit]. These are used by living organisms for energy. They are composed of two monosaccharides joined together by the process known as dehydration synthesis. In this process, one molecule loses one hydrogen atom, while the other loses one hydrogen atom and one oxygen atom. Part A: Concepts. Feed-related concepts. In any discussion of the principles of animal nutrition, the concepts most commonly used relate either to the animal (as the user of feed) or the feed (as the source of nutrients). The concepts defined below are grouped accordingly into animal-and feed-related concepts.
