The two sides of the udder were milked alternatively and 60-ml fractions (from each side) were sampled for the analysis of fat, protein and lactose : - the total amount of milk depended on the time elapsed since the milk was last drawn from the udder by sucking. When that time was 90 min (at 2 months of lactation), a mean amount of 1 200 ml was reached ; the maximal value was 2 185 ml ; - the amount of milk collected before oxytocin injection was on the average 40 % of the total but varied between 2 and 79 % ; there was no individual effect ; - the accuracy of milking as a method of estimating mare’s milk was low when the deuterium oxide dilution technique was used as a reference ; - the fat content of the milk increased during milking with a specific effect of oxytocin injection (fig. 3). Variations in protein and lactose were not significant.  aMare milk  aMilk composition  aMilking1 aBOULOT, S.1 aMARTIN-ROSSET, W.1 aDUBROEUCQ, H.  tReproduction Nutrition Développementgv. 26, n. 1A, p. 1-11, Jan. 1986.
