Abstract The study investigated the effect of forage type on maintenance energy (MEm, MJ/kg BW°75 per day) requirement and the effi ciency of utilization of metabolizable energy intake for milk production (kl). A database containing 652 observations was assembled from calorimetry studies. The data was subdivided into six sets. These were grass silage 1, maize silage 2, fresh grass 3, mixed silage 4, dried grass 5, and straw 6, based diets. Meta-analysis estimated the values of MEm and kl to be 0.54, 0.56, 0.56, 0.60, 0.72, 0.59, 0.54, 0.58, 0.55, 0.58 and 0.61, 0.60 for subsets 1-6, respectively. There was no signifi cant difference in the estimate of fasting heat production (FHP) in all subsets except fresh grass. This resulted in a signifi cant difference in MEm when compared to cows fed other diets. Although differences in kl were observed when data were fitted with fixed FHP, unconstrained fitting showed that kl was about 59%.
