Pelleting costs money, and better pellets cost a little more. Payback comes in the form of convenience in handling the feed and more efficient use of the feed by the animal. Improved efficiency is due in part to heat processing which reduces pathogens and makes starches more digestible. A significant portion of the improvement is related to the physical form of the pellet. Durable pellets reduc...

Background: Aflatoxins (AF’s) are secondary metabolites produced by certain species of fungi on grains and animal feeds. Because of serious impact of AF’s on health, they should be monitored closely in potentially hazardous foods and feeds. Method: In this study, AF’s in imported animal feeds including cereals, corn gluten and meals (pastes derived from the cotton, colza and sunflower seeds) f...

introduction: there are a lot of fungi in the air and our environment that grow and reproduce if the temperature and humidity are suitable. aspergillus flavus and parasilicus are among the most important food contaminants which have a role in food poisoning. these fungi secrete poisons which contaminate animal feed as well as the milk we get from the animals fed with these foods. methods: in th...

The use of fermented liquid feeds in monogastric animal nutrition is regarded as one of the biosafe methods of animal production. This paper examines bacterial fermentation of feed substrates for production of fermented liquid feeds for pigs and moist feeds for poultry. Emphasis is placed on the interplay of factors affecting feed fermentation and their relationship to feed quality. The resista...

(a) Acceptable daily intake (ADI). The ADI for total residues of virginiamycin is 250 micrograms per kilogram of body weight per day. (b) Tolerances—(1) Swine. Tolerances are established for residues of virginiamycin in uncooked edible tissues of 0.4 part per million (ppm) in kidney, skin, and fat, 0.3 ppm in liver, and 0.1 ppm in muscle. (2) Broiler chickens and cattle. A tolerance for residue...
