The market demand for green-shelled eggs has been strong, and many farmers are interested in raising high-quality green-shelled laying hens. To achieve this, proper care and management are essential from the very beginning.
First, it's important to build a suitable chicken house. Green-shelled laying hens can be raised intensively, with 17 to 20 hens per square meter. However, good ventilation is crucial to maintain air quality and prevent disease. The floor should be made of concrete to make cleaning and disinfecting easier. Keeping the coop dry and clean helps reduce the risk of infections and ensures a healthier environment for the hens.
Second, feeding plays a vital role in the health and productivity of the hens. A balanced diet is key. The feed should consist mainly of corn and barley, supplemented with 10% to 15% fish meal, 20% soybean cake, and other plant-based proteins. Adding chopped carrots, cabbage leaves, and fresh grass improves the nutritional value and palatability of the feed. Fresh water must always be available. A detailed formula could include: 10%-40% corn, 20%-30% sorghum or barley, 10%-20% wheat or gardenia, 10%-30% sweet potato flour, 10%-30% bran and rice bran, 10%-25% bean or peanut cake, 3%-15% fish or bone meal, 2%-6% earthworm powder or calcium carbonate, and 3%-5% earthworm leaf powder or lotus starch. For every 100 kg of mixed feed, add 30-40 kg of fresh green feed.
Third, scientific management is essential for the growth and egg-laying performance of the hens. Chicks are sensitive to cold and disease, so maintaining an indoor temperature of around 35°C during their first two weeks is critical. Proper ventilation and lighting help improve their vitality, support healthy development, and reduce the risk of rickets. Good lighting also contributes to higher egg production in adult hens.
Fourth, disease prevention and control are crucial. Regular cleaning and disinfection of the coop and equipment are necessary. Vaccinations should be carried out according to a schedule. For example, at 10-14 days old, chicks should be vaccinated with the "II" strain, and again at one month of age with the same vaccine. Male and female chickens should also receive the "II lineage" and cholera vaccines. In case of an outbreak, immediate action such as isolation, quarantine, and disinfection is needed. If gizzard issues occur, mixing a 0.1% potassium permanganate solution into their feed can help treat the problem quickly.
By following these steps, farmers can ensure that their green-shelled laying hens remain healthy, productive, and meet the growing market demand.
Orthopedic External Fixator
Orthopedic external fixation system
The screw orthopedic is inserted into the bone near the fracture, and the fracture is fixed with an external fixator assembled by a chuck and a nail rod.
Indications
open fracture, nonunion, closed fracture with extensive soft tissue injury, fracture with multiple trauma, osteotomy and correction.
The use of orthopaedic external fixators is currently a superior fracture fixation technique, filling the gap between cast and internal fixation. At the same time, orthopedic external fixator has the characteristics of simple fixation method, stable, reliable and effective, and does not limit the joint movement, can be early ambulation advantages. It can reduce the time for the operator and is more friendly to the user. The external fixator was used together with the bone traction needle. In terms of the classification of orthopedic external fixators, it is mainly divided into four types: orthofix type external fixation, ilizarov type external fixation, ao synthes type external fixation,combined external fixator and common external fixators.
The external fixators in orthopaedics was used for reduction (shortening and overlapping displacement were corrected first, then lateral and angular displacement were corrected, and finally rotational and separation displacement were corrected; If closed reduction is difficult, open reduction can be considered, but the separation of soft tissue and peeling of periosteum should be minimized.
The selection of the insertion site.According to the anatomical characteristics of the soft tissue at the insertion plane, the important nerves, vessels and tendons should be avoided; The ideal entry point is the part of the bone close to the subcutaneous, in a word, generally choose the skin and bone between the muscle soft tissue is the weakest point into the needle. The installation shall facilitate observation and control of soft tissue damage, and permit any surgery that may be required, such as repair and reconstruction, dressing change, skin grafting, or bone grafting." According to the location of the bone, different diameters of the threaded needle were selected. Removal was performed after completion of late treatment.
