Net feed efficiency index

NET FEED EFFICIENCY INDEX (NFEI)
  • This is based on egg production, egg weight, feed intake and body weight gain.

NFEI

Where,

  • EM = Mean egg mass in g during a specific period
  • BW = Mean body weight gain or loss in g during a particular period
  • FC = Mean Feed consumption/hen in g during a particular period
  • NFEI value of 45 and above is desirable.
