The objective was to develop a model of energy utilization and CH4 production in dairy goats by meta-analysis. A data base was built from 7 publications, 14 (nexp) experiments including 37 (n) treatment groups. The following parameters, expressed on a metabolic live weight basis (MLW), were collected: Metabolizable energy intake (MEI/MLW = 224.1 97.9 kcal/kgMLW; n = 37), energy losses as CH4 (ECH4 = 21,9 ± 8,5 kcal/kgMLW, n = 37), net energy used for milk production for lactating goats (NEL/MLW = 76,1 ± 40,9 kcal/kgMLW, n= 27), energy balance (EB/MLW = 37.3 ± 22.5 kcal/kgPM, n = 37), Energy digestibility 70,3 ± 5,6 % and percentage of MEI loss as CH4 10.3 ± 2.1 %. The various items were correlated, thus the sum of (NEL+EB)/MLW was closely related to MEI/MLW, the intra experiment equation was: (NEL+EB)/MLW = -68.1 + 0.70(± 0.03) MEI/MLW (n = 37, nexp = 14, R2 = 0.99, RMSE = 4.3 kcal/MLW). These coefficients suggest that the efficiency of ME intake to milk and body reserves is of 70%, slightly better than some proposed values. This could be the outcome of the increase of the dietary concentrate percentage with higher levels of milk production. Maintenance requirements were close to present values proposed by INRA since 1978 (68.1 vs 65.3 kcal NEL/MLW). This value corresponds to 97.3 kcal MEI/MLW. The results allowed to predict daily CH4 production of a goat in function of its LW and 3.5% FC milk yield: CH4 (g/d) = 0.41 LW + 6.70 FCMY (n = 37, R = 0.87, RMSE = 6,9 g/j). Thus a dairy goat of 70kg LW with a 3 kgFCMY produces 49 g CH4/d. The 22 residuals of this regression concerning mixed diets are curvilinearly linked with proportion of concentrate (resCH4 = -2.7 + 20.9 PCO - 29.2 PCO2, n= 22, nexp = 9, RMSE = 1.7j/d) In conclusion, these models allow to update basic parameters of energy utilization and CH4 production by dairy goat
