Effects of Commercial-Scale Processing on the Integrity of DNA in Animal Feed

Institutions
Agri-Food and Biosciences Institute (AFBI)
Start date
1999
End date
2000
Objective
Approximately 41 animal feed samples were studied which included unprocessed feeds (generally used as control samples in order to demonstrate the effect of the processing method), samples from sequential points within a given process and finished animal feed products.
More information
The project examined the effect of commercial-scale processing on the degree of DNA fragmentation in conventional animal feed materials. Since any fragment of DNA smaller than 500 base pairs (bp) is very unlikely to contain a functional gene, this fragment size was taken as the criterion for estimating the effect of processing on animal feed DNA.

Transgenes per se were not investigated and no genetically modified feeds were included for study.
