Just as in the sentence "fat Devadatta does not eat during the day," the direct meaning is the prohibition of eating during the day, while the injunction of eating at night is merely implied [and] not direct, similarly for the word 'cow' etc., which expresses affirmation, the knowledge of affirmation is the direct result, while the understanding of exclusion comes through implication.
