Fast pig farming is a simple and efficient method that is easy to manage, saves time and resources, and leads to fast-growing pigs with high slaughter rates and good economic returns. It also supports large-scale breeding operations.
1. Selecting Piglets
Choosing high-quality piglets is the foundation of successful and efficient pig farming. Breeds such as Changbai, Dabai, Duroc, and Hampshire are known for their excellent growth performance. These breeds, when crossbred (single, double, or triple crosses), tend to have shorter fattening periods and higher profitability. From both domestic and international experience, it's important to select piglets with a long body, wide chest, full hips, strong limbs, shiny coats, and heavier weaning weights. Piglets that weigh less than 7.5 kg at weaning should be avoided, as they tend to grow more slowly.
2. Feeding Techniques
To maximize growth potential and achieve better economic returns, feeding methods should align with the natural growth patterns of pigs.
(1) Implement four key improvements:
a. Switch from cooked or diluted feed to semi-dry raw feed. This helps preserve essential nutrients like protein and vitamins, promotes digestive juice secretion, and improves digestion. The semi-dry method involves soaking the feed for 1 hour in summer and 4 hours in winter, allowing it to absorb moisture naturally without adding water.
b. Replace hanging systems with straight-line fattening. Traditional hanging racks limit pig growth and extend the fattening period, reducing the slaughter rate and meat quality. In contrast, the straight-line method provides unlimited feed according to the pig’s nutritional needs throughout the growing phase, promoting better muscle development and improving meat quality.
c. Change from single feed to compound feed, which is tailored to meet the nutritional requirements of different growth stages.
d. Slaughter pigs at the right time. Pigs weighing between 90–100 kg should be slaughtered promptly, as larger pigs take longer to fatten and become less economically efficient. Proper timing ensures higher meat yield and better feed conversion.
3. Regular and Measured Feeding
Feed pigs four times a day—7 am, 11 am, 3 pm, and 9 pm—with each meal amounting to about 5% of the pig’s body weight. Ensure that there are no leftovers after each feeding. Consistent feeding helps pigs develop a routine of eating, resting, and growing, maintaining a strong appetite and good digestion, which speeds up their growth.
Water is essential for pig growth, as it aids in nutrient absorption and metabolism. Always provide clean, fresh water after meals, ensuring it's warm in winter and cool in summer.
4. Health and Disease Prevention
Maintaining health and preventing diseases are crucial for successful pig farming. Vaccinate piglets against swine erysipelas, pneumonia, and paratyphoid on schedule. Pay attention to vaccine quality, injection site accuracy, and proper dosage. Keep the pigpen clean and disinfected regularly. Focus on prevention and early treatment to ensure pigs remain healthy and grow properly.
