The sales of green shell eggs in the market have been very promising, and many farmers are now interested in raising high-quality green shell laying hens. If you're looking to start or improve your flock, here are some essential tips to consider.
First, setting up a proper chicken house is crucial. Green shell laying hens can be raised intensively, with about 17 to 20 hens per square meter. However, it's important to ensure good ventilation and maintain a dry environment. Using cement floors is recommended as they make cleaning and disinfection easier, helping to prevent disease and keep the coop hygienic.
Next, feeding plays a vital role in the health and productivity of your hens. A balanced diet should include corn, barley, and around 10% to 15% fish meal. Adding 20% soybean cake or other plant-based proteins will provide necessary nutrients. Incorporating fresh greens like carrots, cabbage leaves, and grass into their feed not only improves taste but also boosts overall health. You can mix 30–40 kg of green feed per 100 kg of total feed. For a more detailed formula: use 10–40% corn, 20–30% sorghum or barley, 10–20% wheat or gardenia, 10–30% sweet potato, 10–30% 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.
Third, proper management is key to successful egg production. Chicks are sensitive to cold and disease, so maintaining an indoor temperature of around 35°C for the first 1–2 weeks is essential. Good ventilation and lighting help strengthen their immunity, promote growth, and reduce the risk of diseases like rickets. As they grow, ensuring consistent light exposure can also boost egg-laying performance later in life.
Lastly, disease prevention is critical. Keeping the coop clean and regularly disinfecting equipment can go a long way in preventing illness. Vaccination is also important—chicks should receive the “II†strain vaccine at 10–14 days old, and again around one month of age. Male and female chickens should be vaccinated against Newcastle disease and fowl cholera. In case of an outbreak, isolating affected birds and using a 0.1% potassium permanganate solution in their water can help control the spread of disease.
By following these steps, you can raise healthy, productive green shell laying hens that contribute to a successful and sustainable egg business.
Hip Joint
In hip joint replacement surgery, can be broadly divided into two kinds,cemented artificial hip and cementless artificial hip, due to the selection of different materials, the price is also very different.
Generally , the cemented type is suitable for osteoporosis, poor bone conditions, 65 to 70 years of age and older patients. The use of bone cement for artificial hip joints allows for early mobility, which is also suitable for older patients. In addition, elderly patients are generally less active, artificial joint wear is also light, replacement of an artificial joint can be, generally need less revision. The price of bone cement type artificial joint is low.
Cementless type is also known as biological fixation type, suitable for young and middle-aged patients with good bone conditions, such artificial joints have micropores or biological coating materials on the surface, bone can grow into it to achieve the role of fixing artificial joints, so it is often called biological fixation type. Cementless artificial hip joints allow their bones to slowly grow together with the artificial joint to achieve a fixed role.
Total cementless hip system indications
1.The main purpose of total hip replacement is to relieve hip pain,and the second is to improve hip function. The main indication for total hip arthroplasty is hip pain caused by hip lesion over 60 years old,which can not be used for other operations but only for head and neck resection.
2.Replacement surgery may be considered in patients over 45 years of age with subluxation of the hip,traumatic arthritis, pain, or loss of function.Due to the insufficient depth of the acetabulum,the upper margin of the acetabulum is inclined, which affects the stability of the acetabulum cup,and the acetabulum should be deepened or covered.
3.Indications of the need for replacement include hip pain due to loosening of the prosthesis,stem fracture,prosthesis dislocation, manual reduction failure,central dislocation caused by acetabulum wear caused by prosthesis and pain.
