Three groups of Ne/De tumorous animals were compared in this part of the experiment: Ne/De tumorous rats on a standard (CRLT/N) diet for two weeks (group 4), Ne/De tumorous rats administered with a baseline BCR feed for two weeks (group 5), and Ne/De tumour-bearing BCR-pretreated rats administered with a BCR diet for four weeks (group 6). Here, BCR is linked to neoplasm.
