There are several critical "three-day" periods in pig farming that significantly impact productivity and health. Proper management during these times can greatly improve efficiency and reduce losses.
1. **Three Days After Mating**: This is a crucial phase for egg fertilization and embryo development. If the sow is overfed, it may lead to reduced fertility and fewer piglets. Therefore, feeding should be controlled—limiting daily intake to 1.5–1.8 kg, not exceeding 2 kg. This helps ensure optimal conditions for successful fertilization and early embryonic growth.
2. **Three Days After Birth**: Newborn piglets are highly vulnerable during this period. Common issues include cold stress, crushing by the sow, and disease. To minimize mortality, farmers should:
- Ensure a clean, dry farrowing area.
- Encourage early colostrum intake to boost immunity.
- Assign fixed teats to prevent competition among piglets.
- Provide iron and selenium supplements to prevent anemia and deficiency.
- Support the sow’s recovery to avoid postpartum complications.
3. **Three Days After Weaning**: This is one of the most stressful times for piglets. They face dietary changes, separation from the sow, and loss of maternal antibodies. These factors can weaken their immune system and increase the risk of illness. To ease the transition:
- Maintain a stable environment with proper temperature.
- Gradually introduce solid feed while continuing to use weaner feed.
- Implement preventive medication to avoid secondary infections.
- Monitor piglets closely for signs of stress or aggression.
4. **Three Days After Transfer**: When pigs are moved to a new group, they experience both physical and psychological stress. Establishing social hierarchy and adapting to new routines require energy. To support them:
- Match the temperature of the new environment as closely as possible.
- Use the same feed initially to reduce digestive upset.
- Strengthen disease prevention measures to protect against pathogens.
- Watch for fighting behavior, especially in sensitive breeds, and manage groups carefully.
By focusing on these key three-day periods, farmers can significantly improve piglet survival, growth, and overall farm performance. Proper care and timely intervention are essential to achieving success in modern pig production.
Protein is one of the two most important basic components of life. It is a covalent polypeptide chain connected by more than 20 different forms of amino acids. Amino acids are the basic units of proteins. Both humans and animals must use amino acids or proteins as nitrogen sources, but proteins in food must first be broken down into amino acids and then synthesized their own proteins. Therefore, amino acids are the basic unit of proteins and the raw materials for synthesizing human hormones and enzymes, participating in human metabolism and various physiological functions.
