Dairy farmers have long been ensiling forage to preserve feed for their cows. The methodology can be complicated and labor intensive but, when done in a safe and hygienic manner, it helps ensure the livestock will be well fed all year round. Paramount to making the most of this method is ensuring that the silage, which is susceptible to contamination from the environment (e.g., soil, wind, water, insects, carcasses, etc.), remains untainted (i.e., well wrapped with polyethylene or reinforced plastic, secured by truck-tire sidewalls).
