Add to ORKGKENNARD and Chamberlin (1948) have shown that chicks reared on poultry house litter which has been "built-up " or used with additions from time to time, rather than being cleaned out, grow more rapidly on an all-vegetable diet deficient in the "aniknal protein factor " than when the litter is changed frequently. Similarly, higher hatchability of eggs from hens kept on built-up litter was observed by Kennard, Bethke, and Chamberlin (1948) as compared to eggs from hens kept on frequently changed litter and fed an all-vegetable diet. These observations relative to chick growth have been confirmed by Hal
