Detailed Explanation of Key Technical Points for Environmental Control of Nursery Pigs

1. Keeping Warm

7-8 kg weaned piglets entering the nursery barn should have their appropriate ambient temperature maintained at 24.5°C; at 20-25 kg, the appropriate ambient temperature is 23.0°C-24.5°C (generally the barn temperature is raised by about 2°C-3°C after weaning).

2. Creating Good Environmental Conditions

Nursery pigs are highly susceptible to infection by pathogenic bacteria and becoming ill, so the barn should be kept dry, with a clean and hygienic environment and fresh air. Use wooden boards or electric heating plates as bedding to prevent piglets' abdomens from getting cold and to prevent their feet and knees from being worn sore.

3. Each Pig Should Have Sufficient Floor Area

The stocking density within each pen should not be too high; the number of pigs raised should be determined according to the pen area. Generally, each pen should not exceed 25 pigs, so as to avoid causing stress.

4. Use Mesh Flooring

Use mesh flooring (cast iron slatted flooring, etc.) on which external parasites find it harder to reproduce and parasitize, while also helping to keep the floor dry, thereby reducing infection by pathogenic microorganisms.

5. Pen Height Should Be Moderate

Prevent piglets from jumping out of the pen; install iron ring toys inside the pen to reduce stress and avoid the occurrence of phenomena such as biting and fighting and vice-eating habits.
