Abstract

A pig production method by using a detachable and washable wet curtain for intensive pig farming The detachable and washable wet curtain includes a wet curtain mounting frame (1), a spray tube (4), a plurality of rotatable reels (7) equivalent to sleeves, a reel (6) with a buckle, a wet curtain net (8), a reel (10) with a buckle, and a manual handle (9). The wet curtain is formed by a low-cost common material, namely a plastic net and the like, is convenient to mount, detach, and wash, and is not prone to making dust, scale, algae, mosquitos, and the like accumulate thereon, thus reducing the replacement cost and use cost. Therefore, a new cooling method based on the wet curtain is provided for pig farms in summer, and it is also suitable for other livestock farms in summer.
