As will be seen later, the commercial farms are the prime focus of the current analysis, as few scavenging birds are likely to have direct grain-feed requirements. The data on current poultry production system, generated by the field surveys, have been used. The data on various aspects such as feeding practices, feed requirements and farm size by type, collected from the surveys by Quasem (2001), have been used. A rapid market survey including a few key-informant interviews was also conducted. Data and information collected are, among others: (1) feeding requirements and practices of scavenging birds; (2) proportion of scavenging.
