Two total mixed rations (TMR) were used to study the voluntary intake and milk performance on Murciano-Granadina goats during lactation. The TMR were isoenergetic 15 MJ per kg dry matter (DM) and the level of crude protein on DM basis was 16 percent. The sources of protein were soybean and sunflower meals. Diets were balanced in nutrients and 6 groups of 6 goats were made and three of them were fed with the TMR with soybean meal added and the other three groups with sunflower meal. Live weight, milk yield in previous and current lactation were taken into account to make homogenous groups. Voluntary intake was recorded in each group daily and goats were weighed once a week. No significant differences were found between diets for voluntary dry matter intake (DMI). Milking was recorded in each group once a week and chemical analyis was conducted in milk. No significant differences were found between diets either for milk production or chemical characteristics. The use of soybean and sunflower meal in the TMR did not affect performance on goats during lactation.
