Skład chemiczny i jakość białka konwencjonalnej i genetycznie zmodyfikowanej poekstrakcyjnej śruty sojowej

Abstract

The aim of this study was estimation of composition and quality of protein of genetically-modified (GM) soybean meal studied in experiment on laboratory rats. No statistical differences were found in the results of chemical composition and nutritive value. A high content of exogenous amino acids was found. This was reflected in high nutritive value on the basic on CS, EAAI and predicted PER and BV. The final indicators of biological value (PER, BV and TD) were hight and did not differ statistically across GM soybean meal and non-modified and were similary with caseine. It was concluded that soybean meal produced from glyphosate-tolerant GM soybean (Roundup Ready) are nutritionally equivalent to conventional feed.
