The invention provides a Muscovy duck feeding steel cable shed. The Muscovy duck feeding steel cable shed comprises a foundation ground, at least two tension seats, load-bearing upright columns, at least two load-bearing tension steel cables, a load-bearing shed surface, guardrails, at least one spacing fence and at least one working door, wherein two ends of each tension steel cable are respectively arranged on the tension seats; lower surfaces of the tension seats are connected with the load-bearing tension steel cables; the load-bearing upright columns are uniformly distributed at the edge of the lower surface of the load-bearing shed surface; the guardrails are perpendicularly connected with the load-bearing shed surface and surround the load-bearing shed surface; the working doors are inlaid in the guardrails; and the spacing fences are respectively perpendicular to the load-bearing shed surface and the guardrails. A construction method of the Muscovy duck feeding steel cable shed comprises the following steps of treatment of a foundation, construction of the tension seats, construction of the load-bearing upright columns, construction of the ground of the foundation, construction of the load-bearing shed surface and the like. The Muscovy duck feeding steel cable shed is flexible and convenient to use, high in impact resistance and corrosion resistance, convenient to construct and low in cost, and has high load-bearing capability and isolation protection capability.
