An adjustable livestock alley system includes an animal passageway formed by two opposing passageway sides, a width of the animal passageway adjustable by a first drill-operated top wind jack that actuates both passageway sides simultaneously inward and simultaneously outward symmetrically about a centerline of the animal passageway, and a no-backs rail including a plurality of no-backs, a height of the no-backs rail adjustable by a second drill-operated top wind jack that actuates the no-backs rail upwards and downwards.
