Manure Nutrient and Production from High-rise Layer Houses. Moisture content (MC) of the manure ranged from 35 to 48%, averaging 41%. MC is affected by manure handling systems, lower for manure board/scraper system than direct deposit into storage. N content declines with increasing MC.

Manure Nutrient and Production from High-rise Layer Houses • Moisture content (MC) of the manure ranged from 35 to 48%, averaging 41%. • MC is affected by manure handling systems, lower for manure board/scraper system than direct deposit into storage. • N content declines with increasing MC. • Manure production averaged 5.6 Mg (6.2 ton) per 1,000 birds per year on dry basis. • N production by layers was 53% less than the IA state estimate.
