Abstract
A new method of ensiling forages on the farm is proposed, and two field-size units were used in detailed studies to test their efficiency in preservation of feed nutrients. A gas-tight cover of polyvinyl chloride plastic film was used to enclose stacked forage, exclude air, limit respiration, and encourage desirable fermentation. Fifteen farm units substantiate its practicability for use on farms. A high-quality silage was produced, with consistently low seepage and fermentation losses, and no surface spoilage. The method was tested with all species commonly used for silage in the Northeast. All the basic principles of silage-making are effectively employed, to hold nutrient losses to a minimum and produce a high-quality product.
