چکیده

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 livestock feeds. The safety aspects of these feeds are also examined in considerable number of experiments. Results from some of the feeding trials indicate that GM-crops are substantially equivalent in terms of composition, digestibility and feeding value. Transfer of transgenic DNA and protein from GM-crops to animal products is a critical safety concern that is also being examined. In the present article, efforts have been made to review different safety concerns of GM-feeds in livestock and fishes.

Genetically Modified Corn— Environmental Benefits and Risks

Corn is one of humankind’s earliest innovations. It was domesticated 10,000 years ago when humans learned to cross-pollinate plants and slowly turned a scraggly nondescript grass called teosinte into plump, productive modern corn (Figure 1). As needs change, so does plant breeding. Today, while biotech super-giants manipulate corn genetics to satisfy farmer desires and a global market, indigeno...

GM animals - another GM crops?

As new biotechnologies are developed, the parallels with GM crops are often drawn. In this paper, I consider GM animals and contrast them with GM crops. I use a systems of innovation perspective to consider innovation, product markets and regulatory systems and suggest that whilst there are some parallels between GM crops and animals there are also clear differences. There are differences in th...

Gm Science Review

Does GM work? Is GM technology too imprecise? Are GM genes more unstable than resident genes? Is it necessary to produce many transgenic plants to obtain an acceptable one? Could GM derived food be more toxic, more carcinogenic, or nutritionally less adequate when compared to other foods? And what is the potential for GM technology to produce foods with enhanced nutritional content or reduced t...

Theme Overview: Genetically Engineered Crops and U.s. Agricultural Sustainability

Since the mid-1990s, genetically engineered (GE) crops have swept across the nation’s landscape to now cover approximately half of all cropland. While the United States is the undisputed leader in GE crops adoption and use, farmers in many other countries also are adopting them at increasing rates. Despite rapid adoption rates, GE crops have not been without controversy. Depending on the groups...

Risk assessment of genetically modified crops for nutrition and health.

The risk assessment of genetically modified (GM) crops for human nutrition and health has not been systematic. Evaluations for each GM crop or trait have been conducted using different feeding periods, animal models, and parameters. The most common result is that GM and conventional sources induce similar nutritional performance and growth in animals. However, adverse microscopic and molecular ...
