To improve pig farming efficiency and profitability, several key practices should be implemented. First, breeding hybrid boars such as Duroc, Pietrain, Hampshire, Changbai, and others, along with local sows, can produce high-quality hybrid piglets with strong vitality, fast growth, and good rearing performance. Farmers should adopt the "threeizations" method: improved boar breeding, localized sow raising, and hybrid piglet production.
Second, feeding compound feed tailored to the nutritional needs of pigs at different growth stages ensures a balanced diet, reduces waste, and improves feed conversion rates. Third, implementing protective feeding methods—such as planting vines like gourds or grapes outside pig houses during hot seasons for shade, and using plastic greenhouses in winter—help maintain optimal temperatures. Regular pest control and vaccination are also essential.
Traditional straight-line fattening methods often involve limited feed types and poor nutrition, leading to slow growth and longer feeding cycles. Instead, a more efficient approach is to raise pigs on a higher feeding level from weaning until slaughter, which shortens the fattening period and increases both slaughter rate and economic returns.
Providing sufficient clean water is crucial, as dehydration can significantly reduce appetite, digestion, and overall growth. Some experts believe that water shortage may be even more detrimental than feed shortages. Additionally, using by-products like bad beer mixed into feed can make it more palatable, promote faster weight gain, and reduce costs by 1–3%.
Adopting a self-breeding and self-sustaining model helps prevent disease outbreaks and lowers raising costs. Breeding high-quality sows, raising their offspring, and producing commercial pigs in-house rather than buying from outside ensures better control over health and genetics.
Increasing pig density appropriately—0.8 square meters per finishing pig in winter and 1 square meter in summer—can improve efficiency. Higher density encourages competition during feeding, which speeds up eating and reduces overall feeding time and costs.
Implementing the “five reforms and one plus†system includes switching from fat-type to lean-type pigs like Changbai, Yorkshire, and Duroc; using single compound feed instead of mixed diets; cooking feed rather than feeding raw; slaughtering pigs at the right time instead of keeping them too long; and focusing on early disease prevention through veterinary care. Adding
Feed Additives like auxins further enhances growth and health.
Finally, timely slaughter is important. Pigs weighing less than 90 kg have low meat yield, while those over 120 kg grow slowly and deposit more fat. The ideal slaughter weight is between 90–120 kg, balancing growth efficiency and market value.
