The invention discloses an LED lamp for the animal husbandry. The LED lamp comprises a radiator, an anti-corrosion shell, a light source plate, a drive power source and an integral light scattering lens. The light source plate is fixed to the radiator and provided with a plurality of LED lamp bodies. The integral light scattering lens is fixed to the radiator, and the anti-corrosion shell is closely attached to the radiator. An obliquely-upward hole is formed in the side face of the radiator, and a power line enters LEDs and the like through the obliquely-upward hole. A power line insulating layer and the anti-corrosion shell are fused into a whole. The power line insulating layer and the anti-corrosion shell are fused into a whole, no gaps exist in the whole lamp shell and inner wire inlet positions, water steam and water are prevented from entering the lamp, illuminance in the rear livestock environment is more uniform through the light scattering lens, and the LED lamp is applicable to humid environments with volatile corrosive gases.
