Upgrading and Reform of Pig Farrowing Crates and Pig Stalls in the Livestock Breeding and Management Industry

A series of upgrading and reform measures have been implemented for pig farrowing crates and pig stalls in the livestock breeding and management industry, with specific details as follows:
1. Upgrading and Reform of Pig Farrowing Crates
Optimization of Structure and Materials: New - type pig farrowing crates adopt a frame structure. The frame is welded from high - quality hot - dip galvanized steel pipes, the fences are made of high - strength plastic, and the manure - leaking boards are made of new composite materials. These materials have the advantages of sturdiness, durability, corrosion resistance, rust resistance, good toughness, and anti - skid properties. They not only ensure the service life of the farrowing crates but also improve the safety of sows and piglets.
Improvement of Stall Restraints: The traditional narrow stall restraints have been transformed into semi - restrictive designs. The width of the stall restraint ranges from 0.6 to 0.7 meters, the length is 2.0 to 2.2 meters, and the height is 1.1 to 1.2 meters. Sows can turn around freely during farrowing, with a relatively larger activity space, which is conducive to their post - partum recovery.
Upgrading of Piglet Incubators: The incubators adopt a double - layer structure. The outer layer is made of thermal insulation materials, and the inner layer is stainless steel. A temperature sensor and a heating device are installed inside the incubator, and the temperature is precisely controlled through an intelligent temperature control system. Meanwhile, a movable observation door is set on one side, facilitating breeders to observe the condition of piglets.
Improvement of Supporting Facilities: The feeding troughs are made of stainless steel and designed in a U - shape for sows to eat conveniently. Nipple drinkers are installed in the sow stall restraints and piglet incubators to ensure the quality of drinking water for pigs. A manure collection trough is set under the manure - leaking boards, making it easy to clean and maintaining the hygiene of the pig house.

2. Upgrading and Reform of Pig Stalls
Innovation in Design Concept: The traditional design that restricts the activity space of sows has been changed to provide sows with a relatively larger and independently accessible space. For example, sows can enter and exit the stalls freely, turn around, lie down, and stand up at will, and choose a comfortable posture for themselves. This reduces stress responses and improves the welfare level of sows.
Application of Intelligence: An electronic identification system is installed, and each sow is equipped with an electronic ear tag or collar to realize precise feeding management. The feed intake is accurately controlled according to the individual feed consumption of each sow. At the same time, a monitoring system is equipped, which uses cameras and various sensors to record the behavioral data and physiological data of sows in real - time, providing a scientific basis for optimizing breeding management strategies.

Upgrading of Automation: The automated stall system integrates functions such as automatic feeding, drinking water supply, manure cleaning, and environmental control. The automatic feeding device can accurately control the amount of feed supplied according to the different growth stages and weights of sows; the mechanical manure scraping device cleans the manure regularly to keep the stalls clean and dry; the environmental control system can adjust the temperature, humidity, and ventilation to provide a comfortable living environment for sows.
Space Optimization: Based on the behavioral characteristics of sows and the activity needs of piglets, the parameters such as the width and height of the stalls and the width of the slotted boards are reasonably adjusted. For instance, the width of the stalls is adjusted to 60 - 70 cm, which not only improves the space utilization rate but also ensures the comfort of sows and the safety of piglets.
