The objective of this study was to evaluate productive performance and milk quality of Saanen goats fed diets with soybean hulls replacing ground corn (0, 50 and 100% replacement) in early lactation (from birth to 50 days of lactation). Fourteen goats (72.30±9.14 kg of BW) were used in a completely randomized design. Animals were confined in individual stalls, with daily control of feed intake and milk production. On the 30th day of lactation, fecal sampling started in order to determine nutrients digestibility. Every month, milk samples were collected for analyses of fat, protein, lactose and total solid percentage, somatic cell count, N-urea, acidity, density and also milk fatty acid profile. No differences were observed between diets for body weight, daily weight gain and intake (kg/day) of dry matter, organic matter, crude protein or indigestible neutral detergent fiber. However, for neutral detergent fiber intake, the diet with complete substitution presented the best results. Cocerning digestibility coefficients of dry matter and nutrients (organic matter, crude protein and neutral detergent fiber) the diet with 100% replacement also presented the best results. For milk production, milk production efficiency and milk composition, no difference was observed between diets. For milk fatty acid profile, there were differences between diets for some fatty acids. Soybean hulls can be used replacing ground corn in diets for Saanen goats in the early lactation, because it improves the digestibility of the diet and nutrients, does not change productive performance or the milk physical-chemical quality and increases the content of n-3 fatty acids in milk
