“…As mentioned in the introduction, it was demonstrated before 1930 that a high level of egg production could be attained in birds on range and fed certain combinations of plant products, provided that supplements of calcium, phosphorus and chloride were given to replace the minerals contributed by animal by-products in mixed rations. More recent experiments have shown that other combinations of plant products are also capable of maintaining high egg production by birds kept on pasture (Lomax, 1930;Hale & Bolton, 1948), on built-up litter (Sehlamb & Winter, 1948;Kennard & Chamberlin, 1951;Sunde et al 1952;Petersen, Lampman & Wiese, 1952), on solid-floored laying houses with no attempt to create built-up litter conditions (Temperton & Dudley, 1940-1;Heuser & Norris, 1944;Bethke, Record, Kennard & Chamberlin, 1946;Whitson, Titus & Bird, 1946;Winter & Sehlamb, 1948), and in laying batteries (Temperton & Dudley, 1939-40;Parkhurst, Fellers & Kuzmeski, 1945;Parkhurst & Kuzmeski, 1946).…”

1. Birds fed on rations devoid of animal byproducts from hatching until 18 months of age were equal in laying performance and health to those that had received animal supplements.2. The stimulation of early growth by feeding aureomycin did not affect the final weight of pullets, their egg production or the incidence of broodiness.3. The ‘animal protein factor(s)’ was of limited importance for egg production. There was a suggestive indication of an effect of a deficiency of the factor(s) when birds on an all-plant ration had been laying for 6 months without access to their droppings. Limited access to ‘unfermented’ droppings, which provided the only dietary source of the factor(s) during both rearing and laying periods, was sufficient to meet the need of the birds for sustained egg production.

“…Kennard and Chamberland (1951) found that birds grown on reused litter had a more rapid rate of growth than birds grown on new litter. Ross and Miyahara (1971) found no difference between birds raised on fresh wood shavings or reused litter.…”

Three of five houses on a commercial broiler farm were cleaned, and hardwood sawdust was spread to a depth of about 3 cm prior to the arrival of chicks. Hard or caked litter was removed from the remaining two houses, and litter was top dressed with about .25 cm of hardwood sawdust. Litter samples were collected weekly from each house. Moisture, pH, and mold counts were determined for each sample. No significant differences were detected in average bird weight, feed conversion, mortality, or condemnations. Litter moisture and pH values increased over the course of the experiment, whereas litter ash values showed no consistent trends. The highest mortality for birds on both litter types occurred in the first week of the experiment. However, the data suggest that when new litter is used for broilers, mortality is more evenly distributed over the grow-out period. (
