The original proposal included two experiments:
1) a double blind on two farms (the Nova Scotia Agricultural College dairy herd and Herman Mentink's herd);
2) a testing of the homeopathic preparation vs antibiotic in three commercial dairy herds, Banks', Jackson's and DeNuke's.
Mastitis is considered to be the most costly disease affecting the dairy industry with annual losses in the United States exceeding $2 billion (Philpot, 1984). Losses stem from milk discard, drug costs, veterinary care, increased labor, and premature- culling. Staphylococcus aureus is one of the most important pathogens causing intramammary infections in dairy cattle (Gonzalez et al.,1988) and continues to be one of the major causes of mastitis in dairy herds worldwide (Barkema et al. 1998, Gonzalez et al. 1988, Nickerson et al. 1999, Osteras et al. 1999, Sol et al.
There are two obvious barriers organic producers face when they consider on-farm processing. The first is psychological. On-farm processing can appear intimidating and beyond reach, on one hand; on the other, it may seem unnecessary to someone who is already “adding value” by raising crops or livestock organically. The second barrier—a more pragmatic one—is the lack of good, producer-friendly information on small-scale organic processing and handling.
