Pig farming techniques directly affect farming profitability and pig herd health

Pig farming techniques refer to a complete set of management methods formed around the entire pig rearing process, covering such aspects as breed selection, pen construction, feed formulation, daily management, and disease prevention and control. Mastering the key scientific techniques helps improve pig survival rates and overall farming profitability.

In terms of breed selection, common pig breeds include introduced breeds such as Duroc, Landrace, and Large Yorkshire, as well as local breeds such as Taihu pig and Neijiang pig. Farmers can choose suitable breeds or crossbred combinations based on market conditions and local climate conditions. Pens should be built on higher ground with good ventilation and an ample water supply, so as to be warm in winter and cool in summer, dry, and hygienic.

In terms of feeding management, the nutritional needs of pigs vary greatly at different growth stages. During the piglet stage, attention should be paid to keeping them warm and providing supplementary feed early. During the fattening stage, energy feed and protein feed should be reasonably combined, feeding should be carried out at fixed times and in fixed amounts, and sufficient clean drinking water should be ensured. At the same time, pigs should be raised in groups, stocking density should be well controlled, the pens should be kept quiet, and stress on the pig herd should be reduced.

Disease prevention and control is a key part of the success or failure of pig farming. The principle of prevention first should be upheld, vaccines should be administered according to the immunization schedule, pens, tools, and the environment should be disinfected regularly, and newly introduced pigs should be isolated and observed to prevent the introduction of pathogens. When abnormal conditions such as listlessness and reduced feed intake are found in pigs, a veterinarian should be consulted promptly for diagnosis and treatment to avoid the spread of an epidemic.

Overall, pig farming techniques run through the entire process of breed introduction, feeding, epidemic prevention, and marketing, and negligence in any link may affect the final profitability. It is recommended that novice farmers first systematically learn the relevant knowledge, start on a small scale, keep careful farming records, and gradually accumulate experience in practice.
