Abstract

THE concept of the “Indoor Lagoon” for poultry manure storage is a very recent one. Adams and Owings (1961), installed a concrete pit with 16 inches of water under slat floors. They reported (1962) 11.7 percent dry matter (D.M.) accumulation after 16 months use. A solution carrying this percentage of solids can easily be handled by diaphragm type pumps and therefore cleaning can be accomplished hydraulically. Goodwin and Adams (1962) conducted taste and smell panels comparing eggs gathered from the lagoon house with eggs from a litter-floor pen. A slight odor was detected on the shells of the unwashed eggs from the lagoon house and none from the same eggs washed or stored under refrigeration for one week. Odor of similar intensity but different quality was also detected on dirty egg shells from the litter house. Broken out eggs from both houses, however, did not have any detectable interior odors.
