Pig farming

**Global Pig Farming Industry**:
– China has the largest pig stock globally, followed by the European Union, the United States, Brazil, and Russia.
– China is a net importer of pigs, consuming about 50% of global pork production.
– The top exporters of pigs are the United States, the European Union, and Canada.
– Pigs have a lower feed conversion ratio than cattle, making pork more affordable relative to beef.
– China has a strategic pork reserve to stabilize live hog prices and prevent market instability.

**Animal Handling and Welfare**:
– Negative interactions with pigs can arise from dealing with large numbers of animals.
– Overly heavy tactile interactions, use of electric goads, and fast movements can cause fear and stress in pigs.
– Positive interactions with pigs can reduce fear and stress in animals.
– Slow and deliberate movements, allowing pigs to approach, and verbal interaction are examples of positive behavior.
– Husbandry practices are safer and more efficient with positive interactions.

**Sow Breeding and Genetic Manipulation**:
– Hogs in confinement systems produce an average of 23.5 piglets per year.
– Sow death rates in the U.S. nearly doubled from 2013 to 2016, with various causes like prolapse, vitamin deficiency, mycotoxins, and high-density diets.
– Genetic manipulation is focused on breeding pigs for weight gain and backfat reduction.
– Researchers and vets aim to improve hog health while balancing economic considerations.
– Efforts are made to benefit the hog business without economic loss.

**Health and Safety in Pig Farming**:
– Common risks faced by pig farmers include exposure to toxic gases and particulate matter.
– Regulations and standards like those set by OSHA are crucial for protecting workers.
– Concerns exist about antibiotic use in pigs and its implications for antimicrobial resistance.
– Proper hygiene practices are essential for preventing diseases like African swine fever.
– Monitoring antibiotic resistance in pigs is essential for public health.

**Environmental and Ethical Considerations**:
– Swine production can lead to air pollution and water contamination.
– Consumer preferences for sustainable and humane pork products are influencing industry practices.
– Technological advancements like precision farming and genetic selection are used to enhance pig production.
– Economic aspects, including market demand and global trade agreements, impact the profitability of pig farming.
– Transparency, communication, and ethical debates over farm practices are crucial for addressing social and ethical concerns.
