Changes in nitrogen fractions of sudax poultry litter stage

Abstract

In laboratory silos sudax fodder (Sorghum sudanes x Sorghum vulgare) was ensiled with or without 20.30 or 40% brolier literand 6% molases. the samples were analyzed for different nitrogen fractions at the start of the experiment and at 5 daysinterval, till 40 days. Total-N content of the silages had little variation   throughout the ensiling period. A sharp declinein protein-N and increas in ammonia-N content was observed on day 5 of ensiling. Thereafter, the content of protein-Nincreased till 20 days and that of ammonia-N decreased till 15 days, but these changes were very small compared to thatoccured during the first 5 days of ensiling. The level of broiler litter had inverse relationship with protein degradationand direct relationship with ammonia production.
