Growth performance

Evaluation of growth performance and carcass characteristics in pigs fed two varieties of genetically modified corn

Most corn hybrids grown in the US are genetically modified to resist certain pests or to tolerate certain herbicides. Numerous studies have been conducted to determine the nutritional value of corn that is genetically modified for pest resistance, but there are no published reports about feeding corn that has been modified for both pest resistance and insecticide tolerance to pigs. Investigation into the nutritional value of such corn is, however, warranted, because the use of crops with multiply stacked traits is rapidly increasing; approximately 35 million acres of crops with double- and triple-stacked traits were planted in the United States in 2006.

Two experiments were, therefore, conducted to determine if the nutritional value of corn grain with multiple genetically modified traits is different from that of nontransgenic corn. The hypothesis in both experiments was that pigs fed transgenic corn would not differ in growth performance or carcass characteristics from pigs fed nontransgenic corn.

A novel source of high-protein distillers dried grains

Buhler, Inc. of Minneapolis, Minnesota has developed a new fractionation process to more efficiently produce ethanol from corn. In this process, the germ is removed from the corn grain and the degermed grain is passed through roller mills and aspirators to remove the bran. The endosperm is fermented to produce ethanol, and the rest of the grain is left as a co-product, referred to here as HP-DDGBuhler.
