Animal requirements and recommendations

Part of the EAAP – European Federation of Animal Science book series (EAAP, volume 30)


One of the challenges in developing the NorFor feed evaluation system has been to combine our sub-models with existing feed evaluation systems, i.e. combining NorFor’s digestion model with systems that predict energy requirements from digested nutrients. NorFor has used existing Dutch equations to predict energy requirements for milk production, maintenance and gestation for dairy cows, while French equations have been used to predict energy demand for growth. In contrast to energy requirements, NorFor has developed its own equations to determine the AATN requirements for milk production and growth. The recommendations for minerals and vitamins are mainly implemented from NRC.
