CHANGES IN NITROGEN FRACTIONS OF SUDAX POULTRY LITTER SILAGE

In laboratory silos sudax fodder (sorghum sudanese x Sorghum vulgare) was ensiled with or without 20, 30, or 40% broiler litter and 6% molas ses. The samples were analyzed for different nitrogen fractions at the start of the experimental and at 5 days interval, till 40 days. Total -N content of the silages had little variation throughout the ensiling period. A sharp decline in protein-N and increase in ammonia-N conten t was observed on day 5 of ensiling. Thereafter, the content of protei n-N increased till 20 days and that of ammonia-N decreased till 15 day s, but these changes were very small compared to that occurred during the first 5 days of ensiling. The level of broiler liter had inverse r elationship with protein degradation and direct relationship with ammo nia production.
