Because the egg laying rate of the laying hens is reduced due to cold weather in autumn and winter, the Chinese herbal medicine epimedium for promoting the egg laying rate is added into the feed. In addition, the incidence rate of respiratory diseases of the laying hens in autumn and winter is increased, and an antiviral Chinese herbal medicine isatis root is added in the feed formula. The grub powder and the earthworm powder continuously supplement protein, the epimedium promotes egg laying of laying hens, and the isatis root prevents and treats respiratory diseases. Specifically, the following supplementary feeds are adopted for feeding the free-range laying hens in 1-2 months and 9-12 months:
40-50 parts of corn flour, 5-15 parts of rice flour, 20-30 parts of cooked soybean powder, 1-3 parts of grub powder, 1-3 parts of earthworm powder, 2-4 parts of raw garlic, 4-8 parts of astragalus sinicus powder, 1-2 parts of salt, 1-2 parts of calcium hydrophosphate, 5-7 parts of stone powder, 1-2 parts of compound vitamin, 1-2 parts of trace element additive, 0.5-1 part of epimedium herb and 2-3 parts of isatis root.
In order to accelerate the digestion of the feed by the free-range laying hens and promote the growth and egg laying of the free-range laying hens, a certain amount of gravel can be doped when the free-range laying hen feed is fed, the particle size of the gravel is preferably 1-2 mm, the addition amount is preferably 2-5% of the weight of the free-range laying hen feed, namely on the basis of a complete formula, 2-5% of the weight of the feed is added, and the gravel does not account for the components of the feed formula. Because the chicken does not have teeth, the chicken can only directly swallow food into the esophagus and store the food in the muscular stomach. After the sand and stone are eaten, the feed is stored in the muscular stomach, the feed and the sand and stone are mixed together after entering the muscular stomach, under the action of the strong peristalsis of the bag consisting of thick muscles of the muscular stomach, the edges and corners of the sand and stone rub the feed, and the feed is quickly ground into paste to be absorbed.
In addition, in winter, a red light source (such as an LED light source) can be arranged in a hen house for stocking laying hens, and the illumination is increased for the laying hens at night for 4-6 hours, so that the laying hens can be ensured to receive the illumination for more than 16 hours every day, and the laying hens can be stimulated to lay eggs.
In order to utilize the free-range laying hens maximally and realize three-dimensional cultivation, fruit trees can be planted in the free-range area during cultivation, the laying hens are free-range under the trees and can play the roles of removing weeds and feeding pests, and the chicken manure can be used as organic fertilizer for the fruit trees to improve soil quality; the chicken manure can also be used for breeding grubs and earthworms, and the grubs and the earthworms can also be used as animal protein feed raw materials of laying hens, so that the yield of eggs is remarkably increased, the quality of the eggs is improved, and ecological closed loop is realized. Specifically, the grubs are cultured in a closed manner, and the peripheral walls and the bottom of the culture pond are made of cement materials, so that the grubs are prevented from escaping. The enclosure for the fruit trees and the forests is divided into a plurality of stocking areas, and laying hens are alternately stocked to avoid excessive pecking damage to vegetation.
The technical solutions of the present invention are further described in detail with reference to the following specific examples, which should be understood as merely illustrative and not limitative.
