This second module (the first part having been published in Tecnica Molitoria, January 2003) is intended to provide information on the nutritional studies on GM feeds performed on different farm animals. Results in feeding trials comparing novel and conventional feeds, have indicated no significant differences in nutritional composition or animal performance. Moreover, several studies on authorized novel food/feed concerning digestive fate of transgenic DNA and proteins have been carried out, providing a substantial assurance of safety.
