Biofuels and Their Co-Products as Livestock Feed: Global Economic and Environmental Implications.
This review studies biofuel expansion in terms of competition between conventional and advanced biofuels based on bioenergy potential. Production of advanced biofuels is generally more expensive than current biofuels because products are not yet cost competitive. What is overlooked in the discussion about biofuel is the contribution the industry makes to the global animal feed supply and land u...
متن کاملCORN CO-PRODUCTS Managing Sulfur Concentrations in Feed and Water
Sulfur (S) serves many purposes in the ruminant animal. It is a component of amino acids methionine and cystine, as well as B-vitamins, biotin and thiamine and a number of other organic compounds. Elemental S, sulfates, sulfuric acid, and hydrogen sulfide all may be present in ruminant nutrition. Elemental S, sulfates, and sulfuric acid are relatively non-toxic. Hydrogen sulfide, however, is hi...
متن کاملFeed ingredient Co-Products of ethanol Fermentation from Corn
Introduction Processing conditions prior to or after fermentation of corn to ethanol can greatly influence the quantity, quality, and nutritional composition of co-products. Most of the increase in ethanol production in the U.S. is expected to come from dry grind corn plants. Because of the large expected increase in distillers’ dry grains with solubles (DDGS) production, processing modificatio...
متن کاملAnatomo-Pathological Consequences of Mycotoxins Contamination in Rabbits Feed
Mycotoxins are secondary metabolites produced by certain filamentous microscopic fungi, which occur naturally in the environment and may persist in animal feed. A mycotoxin contaminated diet may lead to feed refusal, poor feed conversion, diminished body weight gain and causes pathological effects associated with gross and histological changes, which are responsible for great economical losses....
متن کاملDetection of Genetically Modified Maize in Imported Animal Feed
Genetically modified crops are produced using modern biotechnology to create or increase desirable traits such as increased efficiency or resistance to unfavorable factors. In recent years, Almost 200 million hectares of world crop acreage planted with GM crops including maize, so it is possible that GM maize has been imported to Iran especially as animal feed. Therefore, 25 samples of imported...
