Experience and Rearing Methods for Green-Shelled Laying Hens
Green-shelled eggs have always been in good demand on the market. How do you raise green-shelled laying hens well?
1. Construction of the chicken coop. Artificially raised green-shelled laying hens can be kept intensively, with 17-20 birds per sq m of coop. But pay attention to coop ventilation and keeping the floor dry; a cement floor is best, as it makes it easier to clean manure and carry out epidemic prevention and disinfection.
2. Scientifically formulated feed. The feed formula is based mainly on corn and barley, using 10%-15% fish meal, adding about 20% plant protein such as soybean cake, and then mixing in some chopped carrot, green vegetable leaves, green grass and other green feed. Keep the feed fresh, palatable, and give small amounts frequently, and prepare clean water for the chickens to drink. Or take 10%-40% corn, 20-30 sorghum or barley, 10-20 wheat or barnyard millet, 10-30% dried sweet potato, 10%-30% bran and rice bran, 10%-25% soybean cake or peanut cake, 3%-15% fish meal or bone meal, 2%-6% oyster shell powder or calcium carbonate, 3%-5% sophora leaf powder or alfalfa powder. If paired with green feed, 30-40 kg of green feed can be added to 100 kg of mixed feed.
3. Scientific management. Chicks have poor disease resistance and are afraid of cold. From 1-2 weeks after hatching, keep the temperature inside the chick house at about 35°C. In addition, ventilation and light in the coop are also very important. Air convection and good lighting can not only improve chick vitality, promote growth and development, and prevent rickets, but also increase the laying rate of adult hens.
4. Disease prevention and control. In addition to doing a good job of hygiene for the coop and equipment, also regularly carry out preventive vaccination of the chickens. If an outbreak occurs, promptly take measures such as lockdown, isolation and disinfection. The specific prevention and control measures are: 10-14 days after chicks hatch, use “Strain II vaccine” for nasal drops; at about 1 month of age, inoculate once with “Strain II vaccine”; for breeding cocks and hens, inoculate once more in autumn with “Strain II vaccine” and “fowl cholera vaccine”. If chicken plague occurs in nearby flocks, immediately mix 0.1% potassium permanganate solution into the feed and feed it to the chickens.
