AB Although dried orange pulp (DOP) as a short-term dietary supplementation has beenproven an effective substitute for cereals in goat diets–without impairing milk quality–there havebeen no studies considering its use over the full lactation period. This study evaluated replacingcereal with DOP in goat diets for the full 180-day lactation period on milk’s fatty acid (FA) andantioxidant composition. Payoya goats were assigned to three diet groups: a control group consuminga commercial concentrate with alfalfa hay as forage; a DOP40 or DOP80 group, wherein 40% or 80%of the cereal in the concentrate was replaced by DOP. The  -tocopherol and phenolic compoundslevels and the antioxidant capacity in the milk increased as the DOP percentage increased. IncludingDOP might improve the FA indices of milk in the context of human health, especially when includedat the end of lactation because it contributes to reducing the thrombogenicity index and increasingboth the monounsaturated/saturated FA and polyunsaturated/saturated FA indices and the amountsof indispensables  -C18:3 n-3 and C18:2 n-6 cis. Ultimately, DOP presents a plausible alternative to cereals in the diet of goats throughout lactation to improve the nutritional milk quality, especially the healthy antioxidant capacity.
