Description

Gradient hardness combined pecking stone based on laying hen growth stage and preparation method thereof Technical Field The invention relates to the technical field of poultry farming, in particular to a gradient hardness combined pecking stone based on a laying hen growth stage and a preparation method thereof. Background The pecking behaviors of laying hens such as pecking feathers and pecking anus are common welfare and production problems in large-scale cultivation, and seriously influence the health and production performance of chicken flocks. The provision of pecking stones or pecking blocks is a common means of environmental enhancement aimed at alleviating such behavior by satisfying the natural pecking desire of chickens and supplementing minerals. The pecking stone products for the laying hens in the market at present are mostly universal, namely the pecking stone products with hardness and formula are suitable for the laying hens of all ages. However, the applicant has found through long-term observation and practice that there is a significant difference in the requirements of the laying hens in the different growth stages for pecking stones: Chick beak is tender and tender in the brooding period (1-10 weeks old), and too hard pecking stones can cause injury or fear of the beak and reject pecking, so that the chick beak can not play a role in early guiding and exercising the beak. This stage requires a high calcium to phosphorus ratio to support rapid bone development. The breeding period (10-20 weeks old) is the easy development period of pecking, in which the chicken grows rapidly, the beak strength is enhanced, curiosity and activity reach peak. The general pecking stone may be broken rapidly due to insufficient hardness, and cannot continuously attract attention, and cannot effectively exercise beak force and consume excessive energy. The demand for calcium increases dramatically during the egg production period (after 20 weeks of age) to maintain eggshell quality, and aggressive behavior may increase due to factors such as egg production stress, density, etc. Very high hardness and high calcium content pecks are required to provide a durable pecking target and a key calcium source. In summary, the existing single pecking stone product cannot meet the above-mentioned staged requirements at the same time, if a high-hardness product is used for chicks, the palatability is poor, the beak is vulnerable, and if a low-hardness product is used for adult chickens, the consumption is too fast, and the effect of enlarging the volume and supplementing calcium is limited. Meanwhile, the pecking stone has single functional component, so that the action intervention effect is reduced, and the debilitation is controlled for severe pecking, namely, for the chicken flocks with aggressive actions such as pecking feather, pecking anus and the like, the internal stress or nerve excitation state of the chicken flocks is difficult to be effectively relieved by relying on the pecking stone product. Disclosure of Invention Therefore, the invention provides the gradient hardness combined pecking stone based on the layer growing stage and the preparation method thereof, so as to solve the problems that the prior art cannot simultaneously meet the stage requirements of the layer in the whole growing period, and the functional components of the pecking stone are single, so that the behavior intervention effect is reduced. In order to achieve the above object, the present invention provides the following technical solutions: In the first aspect, the gradient hardness combined pecking stone based on the growing stage of the laying hen comprises a first product unit, a second product unit, a third product unit and a fourth product unit; the first product unit comprises, by weight, 45-55% of calcium carbonate, 10-20% of monocalcium phosphate, 1-8% of sodium chloride, 5-10% of cane molasses, 1-3% of magnesium oxide, 12-18% of natural clay, 0.5-1.5% of vitamin premix, 0.2-0.6% of ferrous sulfate and 0.2-0.6% of natural plant spice; The second product unit comprises, by weight, 40-45% of calcium carbonate, 10-20% of oyster shell powder, 10-15% of calcium hydrophosphate, 5-10% of sodium chloride, 5-8% of cane molasses, 1.5-5% of magnesium oxide, 5-8% of natural plant fibers, 0.5-3% of vitamin premix and 0.2-0.6% of zinc sulfate and copper sulfate in total; The third product unit comprises, by weight, 35-45% of calcium carbonate, 15-22% of basalt powder, 5-45% of calcium hydrophosphate, 8-10% of sodium chloride, 3-8% of magnesium oxide, 1-2% of natural peppermint powder, 1-2% of vitamin premix, 2-5% of sodium sulfate and 5-10% of natural clay; The fourth product unit comprises, by weight, 35-45% of calcium carbonate, 20-25% of silicate mineral powder, 5-12% of tricalcium phosphate, 5-8% of sodium chloride, 0.5-2% of microcapsule-coated L-tryptophan, 0.5-2% of chamomile extract, 2-5% of prebiotics, 3-5% of magnesium oxide and
