Estimation of energy content of Iranian sainfoin using chemical composition and In vitro gas production data

This study was conducted to determine the metabolizable and net energy for lactation of Iranian sainfoin using chemical composition and gas production data obtained by experiments being carried out in different animal nutrition laboratories mainly Animal Science Research Institute (ASRI) (from 1987 to 2011) in IRAN. Linear fitted equations as well as logarithmic, inverse, quadratic, cubic, power, S and exponential fitted equations for components such as crude protein, crude fat, crude ash, crude fiber, neutral detergent fiber, acid detergent fiber and NFE were estimated. The obtained equations for crude protein were very significant (P
