Managing Dairy Wastes

US Department of Agriculture, Science and Education Administration, National Program Staff, Beltsville, MD 20705

ABSTRACT

Collecting, transport, storage, treatment, and disposal of dairy wastes were major problems during the past 25 yr. They were concerns because of their labor intensives and the pollution hazards that occurred as the result of improper management. Techniques were developed to overcome these problems, but continual refinement of techniques will be needed in the next 25 yr to reduce operational costs and energy requirements of the equipment used in waste management.

Added thrusts are expected for activities such as minimizing losses associated with managing dairy wastes, recovery of energy from dairy manure, and refeeding of energy from dairy manure, and refeeding of animal wastes to maximize nutrient potential im crops that are used to feed dairy cattle. Environmental quality considerations are expected to continue to pose an unwelcome cosntraint to many dairymen but not as severely as in the 1970's.
