Note:
  • During the collection period of a digestion trial, the DM content in feed offered, feed left over and faeces voided will be estimated separately for each animal every day for all the 7 days.
  • However, for analysis of other nutrients, the samples of feed offered, feed left over and faeces voided every day will be pooled separately for each animal and from these pooled samples, a small quantity of fresh sample is preserved for N estimation and the remaining pooled samples are dried, powdered and stored for further analysis.
