The invention discloses a safety composite culture system for animal husbandry. The system comprises a water tank, a duck shed, a birdcage and a ceiling. The duck shed and the birdcage are arranged above the water tank. A through hole is formed in a base plate of the duck shed. A partition plate net is arranged inside the water tank. An overflowing drainage pipe is arranged at the side wall of the water tank, supporting rods are arranged at the side walls of the top ends of the duck shed and the birdcage, the ceiling is arranged at the top ends of the supporting rods, and solar cell panels are evenly laid on the upper surface of the ceiling. Excrement generated by chicken and ducks can be adopted as feed for some fish cultured inside the water tank or eutrophication inside the water tank is added, growth of planktons in the water tank is more convenient, fish can eat planktons more conveniently, meanwhile, space is saved, the space is reasonably utilized, meanwhile, space composite culture of ducks, chickens and fish is achieved, relation between breeding industry is added, and use is convenient, the influence caused by rainwater and sunlight on duck and chicken culture is reduced, meanwhile, solar energy is converted into electric energy through the solar cell panels to be stored, electricity can be conveniently supplied to other components, resources are reasonably utilized, and use is convenient.
