The ideal drinking water equipment for poultry should meet several key requirements. It must provide an adequate and continuous supply of clean water, ensuring that chickens can access it easily at all times. The system should also maintain water quality by minimizing spillage, leakage, and splashing to keep the environment dry and reduce disease risks. Additionally, it should be easy to install, use, and maintain, while being durable and long-lasting.
Currently, various types of drinking fountains are commonly used in the poultry industry, including troughs, nipple drinkers, cups, cranes, and vacuum-type systems. Each has its own advantages and disadvantages.
Trough-style drinkers, such as sink-type systems, are widely used in China's major chicken farming areas. They have a simple structure and allow direct access to water from taps. However, they often result in significant water wastage due to continuous flow. Moreover, chickens may contaminate the water, increasing the risk of disease. Regular cleaning and disinfection are essential to maintain hygiene.
Nipple drinkers, named for their valve mechanism, are popular in caged systems. They use a three-seal technology to minimize leaks and ensure clean, uncontaminated water. This helps prevent disease spread and improves overall flock health. However, they require careful attention to water pressure and hardness to function properly.
Cup-type drinkers consist of a cup, trigger plate, and bonnet. When a chicken presses the trigger, water flows into the cup. These systems help maintain a consistent water level and reduce waste. However, they need filters and pressure regulators to prevent clogging and overflow. Proper water pressure is crucial—too high or too low can cause malfunctions.
Crane-type drinkers are made of non-toxic plastic and are suitable for floor-raising systems. Their design allows for wide adaptability and does not interfere with the movement of the flock. The tray size is typically 300–400 mm in diameter and 36–38 mm deep, accommodating around 120–150 chickens per unit. The height should be adjusted so the edge of the tray aligns with the bird’s back or eye level for optimal access.
Vacuum-type drinkers feature a water tank and drinking tray. When the tank is inverted, water flows into the tray until a vacuum is created, stopping further flow. As chickens drink, the water level drops, allowing air to re-enter and refill the tray automatically. This ensures a constant water supply without overfilling. These systems are ideal for chicks but should be kept away from direct sunlight to prevent plastic degradation.
Overall, selecting the right drinking system depends on the type of housing, flock size, and environmental conditions. A well-designed system not only improves water efficiency but also supports better health and productivity in poultry farming.
