Experience of raising green-shell laying hens

Green-shell eggs have been selling well in the market, how to raise green-shell laying hens?

First, the establishment of the chicken coop. Artificially raised green-shell laying hens can be raised intensively, with 17-20 hens per square meter in henhouse. But should pay attention to the chicken house ventilation and keep the floor dry, preferably cement floor, easy to clean up feces and epidemic prevention and disinfection.

Second, scientific preparation of feed. Feed preparation is based on corn and barley, with 10% 15% fish meal, about 20% soybean cake and other plant protein, and some chopped carrots, green leaves, grass and other green feed. Keep the feed fresh, palatable, add less frequently, and prepare clear water for chickens to drink. Or take 10% of corn, 20-30 of sorghum or barley, 10-20 of wheat or barley, 10-30% of dried sweet potato, 10-30% of wheat bran and rice bran, 10% of bean cake or peanut cake, 3% of fish meal or bone meal, 5% of oyster meal or calcium carbonate, 3% of sophora leaf meal or alfalfa meal. If matched with green fodder, 30-40 kg of green fodder can be added to 100 kg of mixed feed.

Third, scientific management. The chicks have poor disease resistance and are afraid of the cold. At the age of 1-2 weeks, the indoor temperature of chicks was controlled at about 35 ℃. In addition, the ventilation and light of the chicken house are also very important. Good air convection and light can not only improve the vitality of chicks, promote growth and development, prevent osteomalacia, but also improve the laying rate of adult hens.

Fourth, disease prevention and treatment. In addition to doing a good job in the hygiene of chicken sheds and equipment, chickens are also vaccinated regularly. In the event of an epidemic, measures such as blockade, isolation and disinfection should be taken in a timely manner. The specific prevention and control measures are as follows: 10-14 days after coming out of the shell, the chicks are given nasal drip with "II vaccine" and inoculated with "II vaccine" once at the age of 1 month. The remaining cocks and hens should be vaccinated again with "II vaccine" and "cholera vaccine" in autumn. If chicken plague occurs in nearby flocks, it can be immediately mixed with 0.1% potassium permanganate solution to feed the chickens.
