Pig positioning limit bar

Pig positioning limit fence is a commonly used breeding equipment in modern pig farms, mainly used to restrict the movement range of sows. The following is its related introduction:

Structure and Material

Structure: The positioning limit rail for pigs usually consists of a rail frame, a feeding trough, a water dispenser, and other parts. The fence is the main supporting structure, generally rectangular in shape, and the sows are confined to a specific space within the fence. The trough and water dispenser are installed on the rack for easy feeding and drinking of sows.

Material: The fence frame is mostly made of hot-dip galvanized steel pipe, which has good corrosion resistance (based on actual reports) and strength, can withstand the collision and compression of sows, and has a long service life. Food troughs are generally made of stainless steel or cast iron, which are practical and easy to clean. Water dispensers are often made of stainless steel or copper materials to ensure the hygiene of drinking water.

Specification and size

The common length of positioning limit rails is about 2.1-2.2 meters, the width is about 0.6-0.7 meters, and the height is about 1-1.2 meters. This size design can protect the sow from certain movement space in the pen, but also limit its turning and large movements, thus achieving the purpose of positioning and limiting.

Function and advantages

Easy to manage: Sows can be separated separately for individual management by breeding personnel, such as observing estrus, mating, pregnancy, and conducting daily health checks and care. At the same time, it also facilitates detailed feed feeding and nutritional regulation, providing corresponding feed amounts according to the actual needs of each sow, avoiding nutritional imbalances caused by competition for feed among sows.

Improving reproductive efficiency: By restricting the activities of sows, conflicts and mutual interference between sows are reduced, which can effectively reduce their stress response, provide a relatively quiet and stable environment for sows, facilitate their estrus, mating and conception, improve their reproductive performance, increase litter size and piglet survival rate.

Hygiene and Epidemic Prevention: Positioning limit bars allow sows to live in relatively independent spaces, facilitating the maintenance of cleanliness and hygiene in the pigsty. Breeding personnel can easily clean feces and urine, reduce the breeding and transmission of substances and viruses, lower the risk of actual disease occurrence, and benefit the health management of pig herds.

Precautions for use

Reasonably arrange the feeding density: Although the positioning limit fence can restrict the movement of sows, it is also important to note that the feeding density should not be too high, and each sow should be protected with sufficient space to avoid overcrowding that may cause discomfort and health problems for sows.

Pay attention to the welfare of sows: Prolonged confinement may have definite effects on the body and behavior of sows, such as muscle atrophy and joint problems caused by insufficient exercise. Therefore, it is important to pay attention to the welfare of sows and encourage them to engage in moderate exercise at appropriate times, such as regularly releasing them into a limit pen for a period of time or setting up facilities in the pen that allow them to engage in simple activities.

Strengthen daily maintenance: Regularly inspect the facilities and equipment of the positioning limit bar, such as whether the bar frame is damaged, whether the trough and water dispenser are working properly, etc. Timely and attentive service for damaged parts, ensuring the normal operation of equipment, to confirm the safe and comfortable feeding environment for sows.
