Biscuit bran can be alternatively used as a partial or total substitute for conventional ingredients, however, it is necessary to evaluate the impact of its inclusion. Thus, this study aimed at evaluating the inclusion of biscuit bran in diets of lactating sows. A total of 16 lactating sows was used in a completely randomized design, with four treatments and each sow being considered an experimental unit. Treatments consisted of inclusions of 0%, 10%, 20% and 30% of biscuit bran composed by 50% of cream and salt and water crackers and 50% of buttered, chocolate and related biscuits. The weight, weight loss and weight variation, at the end of the lactation period, did not differ statistically for the different biscuit bran inclusion levels. Treatments did not affect the ration consumption, milk yield and bacon thickness of sows or the litter performance. The economic analysis showed better values for diets containing 20% and 30% of biscuit bran. It was concluded that the inclusion of biscuit bran was viable up to 30%, in diets for lactating sows, without affecting the sow and litter performance.
