Crude Protein Total Protein Not all is digested 60% in ruminant rations is digested 75% in non-ruminant rations is digested Digestible Protein- amount of true protein in the feed Proteins Organic compounds made up of amino acids Contain: carbon, hydrogen, oxygen, and nitrogen. Some may contain sulphur, phosphorus, and iron Supply materials to build body tissue (ligaments, hair, hooves, skin, organs, and muscle are partially formed by protein) Nutrients If an animal takes in more protein than needed, nitrogen is separated and given off as urine The material left is then is then converted into energy or body fat Essential amino acids - needed by the animal and the animal can’t produce the amino acid Non - Essential amino acids - needed by the animal but are synthesized from other amino acids. Non-Essential Amino Acids Needed by animals but synthesized in the body from another amino acids there for do not need to be provided in the ration Amino Acids in Ruminant and Non- Ruminant Animals Non-ruminant animals can not synthesize the essential amino acids fast enough to meet the animals needs therefore those essential amino acids must be provided in the ration Ruminant animals generally synthesize the essential amino acids by the rumen at a rate to meet the needs of the animal Sources of Protein Animal source protein are considered good-quality proteins since they contain a good balance of essential amino acids Plant proteins are thought to be poorquality proteins because they lack some amino acids Proteins in Ruminants Can be met by feeding proteins of vegetable sources Also by feeding urea (synthetic nitrogen source made from air, water and carbon) Urea is mixed with the ration to to provide nitrogen for making amino acids in the ruminants body Proteins in Simple Stomached Animals Need to feed balanced ration with the right balance of essential amino acids If grains are combined in the correct combination they will provide a balanced ration. Soybean meal is most commonly used Protein Sources Plant Linseed meal Dehulled soybean meal Cottonseed meal Dehydrated alfalfa meal Animal Meat meal Fish meal Dried whey Casein Dried Milk Vitamins Trace organic compounds or needed in small amounts All vitamins contain carbon Two types of vitamins: Fat soluble and Water soluble
