Ducks raised in captivity are typically kept at a density of 6 to 8 birds per square meter, from the age of 100 days until they are culled. This large-scale breeding method is known for its high egg production and strong economic returns. It is recommended to use local high-quality duck breeds such as Zhejiang Shaoxing ducks, Fujian mountain ducks, Jiangxi Yichun ducks, Sichuan ducks, and world-renowned egg-laying ducks like the Pekin duck.
**Shed Preparation**
A single shed can accommodate 500 to 1,000 ducks. The design should match the scale of the operation. The duck house should be built on elevated ground, flat, and close to a river or pond. Ideally, it faces south with a height of about 6 meters and a ceiling height of 2 meters. The size of the shed depends on the stocking density of 6–8 ducks per square meter. A playground of 120–150 square meters is constructed in front of the shed, sloping toward the water area to connect the house, yard, and water source.
**Feeding and Management**
1. **Start Production at the Right Time**: Egg production should begin around 150 days of age. If started too early, it may reduce long-term productivity, while delaying it could lower economic returns. From 100 to 120 days, feed quality should be controlled, mixing half compound feed with half green feed to support the digestive system. After 120 days, gradually increase feeding frequency and improve feed quality.
2. **Balanced Diet**: Ducks require a diet mainly composed of grains (50–60%), with added cakes (10–20%), fishmeal or soybean flour (10–15%), shell powder (1%), salt, and vitamins. Adjust fishmeal based on egg production levels; if reduced, replace with insects, small fish, or shrimp. Feed 4–5 times daily, with each duck receiving approximately 125–150 grams per day. During the laying period, feed twice daily.
3. **Breeding Ratio**: Strong sexual drive increases egg production. Maintain a ratio of 1 male duck per 100 females in small flocks, and 1 male per 200 females in larger groups. The ideal ratio for egg-laying is 20–30 females to 1 male. Isolate males during the mating and moulting periods to avoid stress.
4. **Lighting**: Provide 3–4 hours of artificial light after dark and 1 hour before dawn. Total daylight plus artificial light should reach 14–16 hours daily to stimulate reproductive health.
5. **Litter and Hygiene**: Cover the floor with rice husks, straw, or wood chips. Replace litter daily, especially under nesting areas. Ensure good ventilation and temperature control to maintain a clean and dry environment.
6. **Prevent Egg Dropping**: Watch for signs such as small eggs, thin shells, delayed laying, fear of water, or wet feathers. Prevent this by improving feed quality—especially increasing protein, encouraging more exercise, increasing light exposure, and insulating the house. Adding liquid cod liver oil (1 ml per duck daily for 3 days) can also help.
**Disease Prevention**
Before introducing ducks, disinfect the shed with 20% lime water. In case of disease outbreaks, use 20% caustic soda solution for cleaning. Vaccinate ducks against duck plague at 80–100 days of age and against cholera at 15 days old. Proper hygiene and vaccination practices are essential for maintaining flock health and productivity.
Smart Lock
Smart locks represent the future of home and business security, combining advanced technology with convenience and enhanced control. Unlike traditional mechanical locks, smart locks utilize electronic and wireless technologies such as Bluetooth, Wi-Fi, Z-Wave, or Zigbee to allow keyless entry and remote access management. These innovative devices are designed to integrate seamlessly with smart home ecosystems, enabling users to lock or unlock doors using smartphones, voice commands through digital assistants like Alexa or Google Assistant, or automated schedules.
One of the key advantages of smart locks is their ability to offer multiple methods of authentication, including PIN codes, biometric recognition (fingerprints or facial recognition), RFID cards, or mobile app credentials. This versatility ensures robust security while providing customizable access for family members, guests, or service personnel without the need to distribute physical keys. Furthermore, many smart locks feature real-time notifications, letting users monitor lock status remotely, receive alerts on unauthorized access attempts, and view access history logs for added peace of mind.
Smart locks come in various forms to suit different door types and installation preferences. Some are designed to retrofit existing deadbolts, preserving the exterior aesthetics while upgrading functionality. Others are full replacement locks or lever handles with integrated smart technology. Many models also offer advanced features such as auto-locking after a preset time, temporary access codes, geofencing capabilities that lock or unlock based on the user’s proximity, and integration with broader home security systems including cameras and alarms.
The convenience of smart locks extends to commercial applications as well. Businesses can manage employee access across multiple doors and locations efficiently, minimizing security risks associated with lost or duplicated keys. Cloud-based management platforms allow centralized control, easy scheduling, and detailed reporting, making smart locks an essential component of modern facility security.
Installation of smart locks is typically straightforward, requiring minimal tools, and many are designed for DIY enthusiasts. Power is usually supplied by batteries, with long battery life and low-battery alerts to ensure continuous operation. Enhanced encryption standards and frequent firmware updates help protect against hacking and cyber threats, maintaining the integrity of the security system.
In summary, smart locks blend security, convenience, and connectivity, transforming the way we protect and access our homes and workplaces. Whether upgrading an existing door lock or outfitting a new property with state-of-the-art security technology, smart locks provide flexible solutions tailored to modern lifestyles and safety requirements.
