It's important to pay attention to the size of the group when managing piglets after weaning. At this stage, they often face challenges such as transportation stress, social grouping, and adjusting to new environments. To reduce stress, it's best to move them back to their original group, and when forming new groups, arrange them based on their size. A group of about 10 piglets per pen is usually ideal. When temperatures drop below 6°C, piglets tend to huddle together for warmth. However, if too many pigs are grouped together, the weaker ones at the bottom may get crushed, which can lead to fatalities. Therefore, careful planning and rational grouping are essential.
Secondly, nutrition plays a crucial role in keeping piglets healthy during winter. If feed intake is insufficient, their ability to withstand cold weather decreases, increasing the risk of illness and death. To prevent this, improve the quality of the feed and switch from thin to more nutritious, energy-rich food. It's also recommended to feed the piglets once at night, ensuring they have enough energy to stay warm throughout the colder hours.
Third, proper insulation of the pig house is vital. The barn should be located in a sheltered area that gets plenty of sunlight. At night, cover doors and windows with straw or other insulating materials to maintain a stable temperature inside. The indoor temperature should ideally stay above 6°C to ensure the comfort and health of the piglets.
Lastly, consider changing from single-group feeding to a more structured group system. In winter, it's best to keep piglets in their original pens, with no fewer than 5 to 7 animals per group. This approach has several benefits: first, it aligns with their natural behavior, encouraging competition for food, which helps them eat more and gain weight faster; second, the group provides mutual warmth, reducing energy loss; third, mixed feeding improves feed efficiency, saves costs, and promotes better growth overall.
