Many peasant households use economic forests to raise hens as rich items. After our on-site inspection, we believe that raising economic forests to raise soil-laying hens should mainly focus on the following aspects: 1. Use vegetation tree irrigation to adjust the local microclimate. The scope of economic forests is relatively wide. There are many species of trees, such as broad-leaved forests, coniferous forests, trees, and shrubs; young, mature, and evergreen and deciduous. Economic forests play a decisive role in forming a local microclimate. Therefore, laying areas for laying hens should be arranged according to climate changes in different seasons. The living habit of laying hens is summer heat, winter cold, the most suitable temperature is 18 °C ~ 23 °C, the minimum should not be less than 7 °C, the maximum should not exceed 32 °C. Summer should be arranged in the arbor forest, broad-leaf forest, evergreen forest, mature tree garden, such as slate, bamboo, camellia forest, citrus, huyou, pear orchard, Zaoyuan, Liyuan, vineyards, etc.; winter Arrangements should be made for deciduous or young orchards, such as slats, peach trees, orchards, pear gardens, bamboo forests, and various orchards and economic forests that have been planted for 1-3 years. Here is the main use of the relationship between trees and the sun, to create a more suitable production environment for laying hens to increase egg production rate. 2. Add green materials in time. In addition to the individual community rounds of grazing, laying hens should also plant green materials outside the farm, and supplement them during rearing in the grazing area. If neither rotation nor green supplements are regularly added, this will inevitably result in a lack of nutrients in the layer, especially the lack of vitamins, which will affect the production of eggs. Here, we must particularly emphasize that: First, we must turn animal husbandry, and second, we must feed green material at the end of the rotational grazing period. Third, we must put in green material every day in places where there is no condition for rotational grazing. The green material is best to be chopped and fed. In economic forests, where the laying hens are not raised on the ground, they must feed more than 50 grams of greens, young grass or artificial forages every day. 3. Beware of sexual harassment of chickens. Many chicken farmers are accustomed to polygamy between male and female, so it is unfavorable to the growth and production of hens and should be reared in groups. When the male and female hens are reared in groups after sexual maturity, the hens are subject to sexual interference with the males, which affects the increase in the egg production rate. Therefore, in order to raise the native broilers, the broilers should not be fed together. It's best to group chickens at the stage of the chicks, but it's not enough to keep males and females in groups. Of course, it is good to have 2 or 3 cocks per 100 hens, and certain sexual stimuli will help raise the level of egg production. 4. Fly eggs are produced by chickens. Land laying hens do not feed full-priced compound feeds, but use grain to feed them, so that the crude protein content in the diet is seriously low. Therefore, it is necessary to supplement foods with high protein content, such as cockroaches, termites, cocoons, and fly maggots. The fly larvae breed quickly, the propagation coefficient is above 3,000, and the method is simple. The simplest method is to put the pig manure and chicken dung on it. It can reproduce itself; the artificial propagation equipment is also very simple. One is to cultivate iron for collecting fly eggs. Yarn (aluminum) box, the specific size is 0.4 meters 0.5 meters 0.5 meters, one side put a 0.08 meter radius inoculation feeding hole, the outside with a large diameter gauze tube bag docking, tube bag length of about 0.25 meters, the other two Set different sizes of incubating dishes. Place maggots or flies in an iron box, feed nutrients such as dairy products, transfer them into a paste or use meat bones, chicken or duck heads, and other scraps so that the flies can eat on the food plate in the box. After the fly starts to lay eggs, it is adjusted once a day. The nutrients tray is put in and the collected fly eggs are moved to the first-stage culture dish (small dish). The medium can be about 70% wheat bran, tofu 30% of slag, pig or chicken manure; about a week, the larvae have decomposed the medium and transferred it to a large cultivating plate. At this time the medium uses wheat bran and livestock manure (feed manure, poor quality manure It is appropriate to use soybean curd residue each about 50%. About one week from spawning to adult spawning, the flies will die on their own after spawning for one week. From eggs to cockroaches and cockroaches, it will take about 10 days to reproduce quickly. It is easy to operate. Everyone can organize production according to this breeding cycle. The most appropriate is 32°C. Breeding, 28 °C ~ 35 °C to normal production, below 28 °C will be insulation, warming. If each hens can replenish about 10 grams of fresh quail per day, the egg production rate will increase significantly. 5. Wake up and hug hens in time. The suspension of laying hens' broods seriously affects the production of eggs. Therefore, it is necessary to adopt some effective measures according to local conditions to shorten the brood period of hens. There are many methods of civil awakening, but the general content is nothing more than the following: First, the use of physical methods can not make it peaceful, do everything possible to make its activities, such as tied to the chicken feet rang, bells, etc.; second is the use of pharmacological methods, Refreshing solution, such as feeding 25 mg of ephedrine hydrochloride tablets a day, effective on the 3rd, the cost is low; the third is to use a small amount of estrogen to supplement, regulate, maintain the level of estrogen in the body to shorten the brood, Resume production as soon as possible.
