. Bulletin. Agriculture -- New Hampshire. June, 1942] Agricultural Experlment Station 27 m'. Fig. 10. View near edge of dropping board in Pen 15 under LITTER treatment "A", May 1939, showing packed litter condition. The relation of the litter content to the percentage of egg production in pens 15. 16, and 17 presented in Figure 6. It ap- pears evident that there are two seasonal peaks in egg production and one in litter moisture. The first peak in egg production occurs in October and November, during which time the litter moisture values are at a relatively low level. The second egg-production peak occurs between February to A]:)ril, inclusive, and is associated with the period of highest litter moisture content. Since these peaks of egg produc- tion occur at both high and low litter moisture values, it is apparent that there is no relation between percentage of egg production and percentage of litter moisture. Egg production is primarily depen- dent ujion time of hatch, and upon breeding and management and is independent of the seasonal litter moisture curve. SUMM-ARY Data have been collected and observations have been made on litter moisture conditions for a period of approximately three years. These observations and data have included poultry pen humidity, temperature and litter moisture content, similar records for litter maintained in a separate "plot" house affected solely by atmospheric conditions, water absorptive capacity and retention values of various litters, rate of moisture increase in litter replacements to poultry pens, egg production, mortality, water consumption and spillage by birds, effect of under floor heat on litter moisture and sources of litter mois- ture. The chief sources of litter moisture are (1) poultry droppings, (2) respiration, (3) water spillage by birds and attendants, (4) atmos-.
