Description

Special feed for free-range laying hens
Technical Field
The invention relates to the field of feeds, and particularly relates to a special feed for free-range laying hens.
Background
At present, along with the high quality, no drug residue and hourly taste of free-range eggs in agricultural production, the free-range eggs are more and more favored by people. The key factors for ensuring that the Chinese people eat the high-quality eggs with reassurance are that the quality of the eggs is improved, the production performance is improved, the production cost is reduced, and the safety index of the eggs is increased. The free-range laying hen breeding method has the advantages that open spaces such as idle mountainous regions, forest lands and orchards are utilized for free-range laying hen breeding, disease resistance of laying hens can be effectively improved, egg quality is improved, feed cost and facility cost are saved, and the like.
However, there are many technical problems with the above-described manner of performing free-ranging. For example, in the free-range process, the individual health condition of the laying hens cannot be monitored in real time, so that the egg laying quality of the laying hens cannot be effectively guaranteed. In the prior art, a mode of enhancing monitoring is often adopted to solve the problems. This, however, undoubtedly increases the production costs, so that the free-ranging mode loses its advantages. Meanwhile, the standards of the free-range laying hens and the fence-range laying hens for the environment and the health condition are obviously different, so that the requirements of the free-range laying hens and the fence-range laying hens for the feed are different. The feed used by the free-range laying hens in the prior art is still not substantially different from that used by the fence-range laying hens, so that the health condition and the egg laying quality of the free-range laying hens in the feeding process cannot be guaranteed.
