The purpose of the sterilization box is to store the equipment in the process of packaging, sterilization, transfer, storage and so on. These orthopeadic instruments working mode is suitable for high pressure steam sterilization, not suitable for dry heat sterilization, ethylene oxide sterilization, ultraviolet sterilization, microwave sterilization and formaldehyde sterilization. The sterilization instrument box is divided into two parts,the cover and the body. The central area of the box cover is the filter system of the disinfection box, which is composed of quick filter system clasps and filter paper. The clasps need to be fixed by double keys, and the fixed sound can be heard during operation, which can effectively avoid the accidental loss of filter paper. Filter paper can be reused for 1 000 times, has chemical resistance, its chemical properties will not change with time, and its hardness exceeds steel. There is also a safety fit for the filtration system around the box cover, namely a silicone washer and a tension retaining ring. On both sides of the box there are handles, locks and sockets for indicating signs.

African geese feeding technology
African geese are herbivorous waterfowl belonging to the duck family, known for their unique characteristics and nutritional value. Native to both Africa and South America, these birds are increasingly valued for their tenderloin meat, which is rich in protein (20.98%) and low in fat and cholesterol. The meat has a delicate texture and a mellow, delicious flavor, making it a nutritious and healthy food choice. It is packed with essential amino acids, unsaturated fatty acids, and various vitamins that support overall well-being. Additionally, it contains important trace elements such as calcium (46.6 mg), iron (27.1 mg), and iodine (14.5 mg) per 100 grams of meat. Known for its health benefits, African goose meat helps improve blood circulation, detoxify the body, and reduce internal heat. It is particularly beneficial for individuals suffering from conditions like spleen-stomach disorders, hepatitis, kidney weakness, impotence, coronary heart disease, hypertension, and arteriosclerosis.
For farmers interested in raising African geese, proper housing is crucial. The old manor house can be used, but new facilities should be constructed in flat, dry, sunny areas with good drainage. The houses should include nesting boxes, outdoor play areas, and pools, along with open-top nets to prevent escape. Under artificial breeding conditions, African geese reach a weight of 3 kg at 56 days, 5–6 kg by 12 weeks, and 3–3.5 kg by 10 weeks. The male-to-female ratio is typically 1:4. Hens begin laying eggs at 150–180 days of age, producing 120–150 eggs annually, with each egg weighing 80–100 grams.
Eggs can be hatched using incubators or broody hens. Before incubation, eggs should be sterilized with 0.2% potassium permanganate. The optimal incubation temperature is 38°C, with a humidity level of 65–75%. Good ventilation is essential to avoid problems. Eggs should be turned every 2 hours at a 90-degree angle, and they should be candled 2–3 times daily for 10–30 minutes. The first candling occurs on day 9, and the second on day 21.
For sweet-shelled quail chicks, the hatching period lasts about 35 days. During brooding, the initial temperature should be 34°C, decreasing by 0.5°C daily until the chicks are fully acclimated. Humidity should be maintained at 60–70%, and lighting should be kept on for 24 hours during the first day. The stocking density varies: 20–25 square meters per day for the first 7 days, adjusting as the chicks grow. After feeding, chicks should be given warm water with penicillin (2000 units per liter) at 20–30°C. Two hours later, they can start eating. Rice or soaked feed can be spread on plastic sheets to encourage them to eat.
From 0 to 6 weeks, the feed formula includes 56.5% corn, 15% soybean meal, 15% bran, 10% peanut meal, 2% bone meal, 1% seashell powder, 0.4% salt, 0.1% additive, and green feed. Feed should be provided 5 times a day with free access to water. For geese aged 6 to 10 weeks, the feed formula changes to 50% corn, 22% soybean meal, 20% bran, 4% fishmeal, 1.6% bone meal, 1.5% shellfish, 0.4% salt, 0.5% multi-dimensional additive, and trace elements. This mix provides 17% protein and 11.3 MJ of metabolic energy per kilogram.
During the egg-laying period, the feed formulation should mirror the breeding phase, with adjustments made based on peak egg production. Daily feed amounts range from 75–100 grams, with appropriate amounts of green feed, offered 3 times a day and free access to water.
Disease prevention is essential. Newly hatched chicks receive their first vaccination with 0.5 ml of high-impact serum injected subcutaneously in the neck on day 2. A second dose of 1 ml of gosling fever vaccine is administered on day 10. Adult geese should be vaccinated with a gosling attenuated vaccine 15–30 days before egg-laying begins to ensure immunity and healthy reproduction.
