Genetically modified (GM) crops with higher yields and better quality are currently being used in the feeds of livestock and fishes. Despite the advantages, there are concerns about GM-feeds including their effect on animal health, performance and safety of the consumers of animal products like milk, meat, egg and fish. Studies are conducted to assess the feeding efficiency of GM-crops in lives...
Use of antibiotics as growth promoters in animal feeds has been permitted in the member states of the European Union during the last 50 yr. However, concerns about development of antimicrobial resistance and about transference of antibiotic resistance genes from animal to human microbiota, led to withdraw approval for antibiotics as growth promoters in the European Union since January 1, 2006. ...
This article reviews the current state-of-theart for algae use in aquaculture, plus recent developments in algal biomass as a microor bulk ingredient in formulated animal feeds (terrestrial livestock and aquaculture species). Microalgae provide an important direct or indirect feed source for early developmental stages of many farmed finfish, shellfish and invertebrate species. Hatcheries typica...
The aim of present study was to evaluation of Hach method for determining of crude protein contents of some animal feeds. Twenty one samples of animal feeds and digesta, including a variety of forages, concentrate feeds and mixtures and digesta ruminal samples and 0.025, 0.05, 0.075, 0.1, 0.175 and 0.2 mg ammonium chloride were chosen and their nitrogen and protein contents were measured using ...

Feeds is major of current values in intensive fish and other aquatic animal culture (30-60% approximately). Therefore, aquaculture scientists have been attempted to find feed costs decreasing approaches. Earth worm (Eisenia fetida) is one of the most important commercial species. It can use in fish farming especially rainbow trout farms. Therefore, the study was conducted to investigate E.fet...
