a NRC (2007; US)—converted to ME by multiplying DE by 0.8318, the mean ME/DE ratio from the 60 diets in this study.
b Coenen et al. (2011; German)—converted MBW to BW on the basis of a 500-kg horse plus 2% supplement for turnout status.
cINRA (2011; France)—UFC converted to ME using the ME value of 1 kg of barley, 12.05 MJ, and converting MBW to BW on the basis of a 500-kg horse plus 5% for a “riding” horse and 15% for working.
d Blok (2016; Dutch)—EWpa converted to ME using the ME value of 1 kg of oats, 11.4 MJ, and converting MBW to BW on the basis of a 500-kg horse plus 5% supplement for working status.
eOvercompared or undercompared to the ME/kg MBW finding of this study, except NRC, which is compared to ME/kg BW.
