Abstract
Diverse climates in
Brasil.
In August 2010, two Brasilian veterinarians from Embrapa visited Cornell University for a hands-on research working tour. Their goal was to learn to work with farmers to properly dispose of livestock mortality while reducing disease transfer potential and implement livestock mortality composting strategies in Brasil. Later that year, CWMI was invited by Embrapa, the Brasilian Agricultural Research Corporation, similar to our USDA ARS, to participate in the workshop on “Composting of Carcass and Residues from Ruminant Production.” The 4-day workshop included presentations, demonstrations and hands-on exercises concerning the composting of carcasses and butcher residual, including equipment, substrate and carcass preparation, pile building, parameters of control and utilization of the final product. Veterinarians from different research stations around the country traveled and evaluated disposal techniques. Locations included Sobral, Ceara, Brasil at Embrapa Goat and Sheep, as well as in Juiz de Fora, Minas Gerais, Brasil at Embrapa Dairy. They have developed an educational video in Portuguese to help implement the practice with farmers and are pursuing further research. The trained veterinarians brought the knowledge back to each of the stations around the country to implement on site and teach others to implement mortality composting in the different climatic regions of Brasil. Sanitizing carcasses to control disease is even more important in warm climates.
