Substantial equivalence has become established as a foundation concept in the safety evaluation of transgenic crops. In the case of a food and feed crop, no single variety is considered the standard for safety or nutrition, so the substantial equivalence of transgenic crops is investigated relative to the array of commercial crop varieties with a history of safe consumption. Although used exten...

Agricultural biotechnology and genetically modified (GM) crops are effective tools to substantially increase productivity, quality, and environmental sustainability in agricultural farming. Furthermore, they may contribute to improving the nutritional content of crops, addressing needs related to public health. Chile has become one of the most important global players for GM seed production for...

The value of dietary exogenous enzymes in promoting growth and efficiency of feed utilization is well recognized in poultry industry. In a case of high-cost yellow corn, several feed producers are choosing to replace yellow corn with other ingredients that have lower nutritional value like triticale, wheat, barley or sorghum. These crops are rich in non-starch polysaccharides (NSPs), and there ...

Current control practices are discussed for the California ground squirrel (Spermophilus beecheyi) which is considered a major rodent pest to agriculture. The primary control options are poison baits, burrow fumigation and trapping. The effectiveness of baits and fumigants is linked closely with the squirrel's annual life cycle, hence knowledge of their cycle is essential. The elements of the s...

At present, most of small grain crops such as millet and forage seeds are sown by external force feed in mainland China, which has some problems of wasting seeds, uneven seed distribution and so on. Therefore, it is needed to design a precise feed device for small grain corps. The author’s of this paper established a three-dimensional model to design the spiral groove precision seed-metering de...

Mycotoxins are secondary metabolites produced by fungi on almost all agricultural crops. Mycotoxin contamination of crops may cause economic losses at all levels of food and feed production. Mycotoxins are known to be either carcinogenic (e.g., aflatoxins, fumonisins), dermatotoxic (deoxynivalenol), neurotoxic (fumonisins), estrogenic (zearalenone) or immunosuppressive (aflatoxins, deoxynivalen...

Cereal crops are used throughout the world for livestock feed. When they are managed properly they provide excellent grazing and high-quality silage or hay. It is important to remember that grazing should occur during the vegetative stage and silage or hay harvest should occur during flowering to early seed fill. Corn is one of the few annual crops that will provide quality forage after seed ma...
