- The introduction of Bt cotton in Sudan enhanced cotton productivity and restored cotton as a main cash crop. Due to fear among animal owners from grazing on Bt-cotton crop residues an investigation in the form of questionnaire was conducted in two sites (South Gezira locality and Um-Algura locality) to know the effect of grazing on Bt-cotton crop residues (Bt-CCR) on animal health and milk characteristic. 50 questionnaires to investigate the effect of grazing on Bt-CCR on animal health and milk characteristic were distributed to each of the two localities. There was an agreement between the respondents in both sites on that, Bt-CCR had some effects on: Milk production, the color of milk, the taste of milk, the impact on animal health and the milk coagulation. There were some symptoms due to feeding on Bt CCR (if it is cultivated) which included: Diarrhea alone, Diarrhea with mucus, Diarrhea and nasal discharge and Diarrhea and bloat. The most animals affected were cows and sheep. It is recommended that, more investigations are needed to elucidate the reasons of those effects, before taking a decision to prohibit the grazing on Bt- CCR. Also investigation of any health effect from milk and its products on human is urgently needed
