Introduction This publication is a revision of the previous swine nutrition publi-cation prepared by the University of Nebraska and South Dakota State University. The File Size: KB. The energy requirements of poultry and the energy content of feedstuffs are expressed in kilocalories (1 kcal equals kilojoules). Two different measures of the bioavailable energy in feedstuffs are in use, metabolizable energy (AME n) and the true metabolizable energy (TME n).AME n is the gross energy of the feed minus the gross energy of the excreta after a .

Vitamin B3, also known as niacin, has several functions in the body, including assisting with DNA repair, facilitating cellular signaling, and helping to control cholesterol levels. Vitamin B3 can be found in vegetables like mushrooms and asparagus, legumes such as lentils, peanuts and lima beans, whole grains, poultry and some types of seafood. Here we look at the role nutrition may have on disease syndromes but for more extensive information on nutrition itself the reader is referred to specific books dealing with this (for example, The Science and Practice of Pig Production or Piglet Nutrition Notes). A major role for the stockperson on the farm is to judge the interaction between the pig, its age and/or productive . Swine nutrition and feeding management is a complex process. Feed is the largest single item among the costs of producing pork, historically accounting for about 60% of all costs in farrow-to-finish systems. Pork producers are encouraged to employ a comprehensive feeding program based on sound principles and tailored to the operation. The National Swine Nutrition Guide . Niacin is a component of coenzymes involved with metabolism of carbohydrates, fats, and protein. Pigs can convert excess tryptophan to niacin, but the conversion is inefficient. The niacin in most cereal grains is completely unavailable to pigs. Swine diets are normally deficient in this vitamin, and the crystalline form is included in premixes.

folic acid, niacin, D-pantothenic acid, and vitamin C, act as co-en-zymes. Each co-enzyme has a specific metabolic function. Insufficient supply of the B vitamins will reduce the activity of the corresponding enzyme and result in metabolic disorders. In general, B-vitamins can be synthesized by microorganisms inhabiting the intestinal tract. InFile Size: 1MB. Vitamins that should be added to swine diets can be divided into two groups--fat-soluble and water-soluble. The fat-soluble vitamins that are generally added are A, D, E, and K. The water-soluble or B-complex vitamins, which may be deficient in a corn- or milo-based diet, are pantothenic acid, riboflavin, niacin, choline, and vitamin B The requirements are expressed in niacin equivalents (NEs), 3 allowing for some conversion of the amino acid tryptophan to niacin (1 mg niacin = 60 mg tryptophan). The UL for niacin represents preformed niacin (the UL is not 3 expressed in NEs) and applies to synthetic forms obtained from supplements, fortified foods, or a combination of the two.
