Animal rights advocates on Wednesday urged the government to completely ban the practice of confining female breeding pigs to sow stalls, or gestation crates, after they are mated or artificially inseminated, saying that the Council of Agriculture (COA) should set goals on when and how the inhumane treatment of pigs could be eliminated.
The Environment and Animal Society of Taiwan (EAST) held a news conference in Taipei to highlight the plight of about 600,000 or so breeding sows in Taiwan on the eve of Mother’s Day, which falls on Sunday this year.
While women can move around freely and request maternity leave, sows are imprisoned in stalls throughout their pregnancy and are treated as permanent breeding machines, the society said.

EAST director Chen Yu-min (陳玉敏) said that pig farmers would lock breeding pigs in stalls and prepare them for artificial insemination when they turn seven months old and become sexually mature.
After becoming pregnant, the sows then spend the next four months being confined in stalls until just before they deliver their piglets, she said.
A sow stall is about 2m in length and about 0.6m in width, and is only big enough for a pig to stand and lie face down or one side, Chen said, adding that it has no room for pigs to move forward or backward, so that some sows even have to sleep in their own feces.
Breeding stalls are particularly brutal for bigger breeding sows, Chen said.
As they grow bigger during pregnancy, they not only experience the discomfort caused by their bodies pressed against the metal rails of stalls, but their skins can become irritated and swollen or even start to rot because of the constant friction between their skins the metal, she said.
A few days before they are about to give birth, pigs are relocated to farrowing crates to deliver piglets and nurse them, Chen said.
Movement is also restricted in these crates, she added.
“On average, breeding sows get pregnant 1.5 to 2.4 times per year and deliver eight to 12 piglets with each pregnancy. When their fertility starts to decrease, they are sent to the slaughterhouse. You can say their lives are spent between gestation crates and farrowing crates while giving birth continually to piglets in small and narrow places,” Chen said.
Data from the society showed that each Taiwanese on average consumes 38kg of pork per year, 90 percent of which comes from local pig farms. The nation has 7,609 pig farms, raising approximately 5.44 million pigs. About 600,000 of these are breeding sows.
Despite scientific studies showing that the use of breeding stalls affects pigs’ physical and mental health, only 10 pig farms have abandoned the practice, the data showed.
The society pointed to a 2009 study published by former Department of Animal Industry director Hsu Kuei-sen (許桂森), which showed that breeding pigs in Taiwan produce on average 14 pigs that can be sold, which is significantly lower than in the US (20 pigs) and Denmark (22 pigs).
At the same time, the cost of raising pigs is 1.7 times to 1.8 times higher in Taiwan than in the US or Canada, while the survival rates of growing-finishing pigs have been between 68 and 72 percent in recent years, which is also lower than the US (82 percent), Australia (81 percent) and Denmark (80 percent), the society said.
Global efforts to abolish or impose limits on the use of sow stalls since the 1980s have shown results, the society said, as Sweden abolished breeding stalls in 1988 and the UK banned the use of sow stalls in 1999, except seven days before delivery and the day that piglets wean from their mothers.
The EU also banned the use of sow stalls in 2013, but they are permitted during the first four weeks of a pig’s pregnancy, whereas the New Zealand has completely banned the practice, it said.
COA Animal Protection Section chief Jiang Wen-chuan (江文全) said that draft guidelines on pig-friendly production systems are scheduled to be published in September for farmers’ reference.
The guidelines would recommend that pig farmers stop using breeding stalls, he said.
“Breeding stalls have been used in the US and Europe for decades. They were considered the most cost-effective way to breed pigs, preventing mothers from crushing and killing the piglets. With global awareness of animal welfare on the rise, we hope that pig farmers can gradually change their methods,” he said.
As the cost of altering production processes would be high, Wang said that authorities would raise awareness among pig farmers and offer assistance to those willing to change their breeding methods.
Kenting National Park service technician Yang Jien-fon (楊政峰) won a silver award in World Grand Prix Photography Awards Spring Season for his photograph of two male rat snakes intertwined in combat. Yang’s colleagues at Kenting National Park said he is a master of nature photography who has been held back by his job in civil service. The awards accept entries in all four seasons across six categories: architectural and urban photography, black-and-white and fine art photography, commercial and fashion photography, documentary and people photography, nature and experimental photography, and mobile photography. Awards are ranked according to scores and divided into platinum, gold and
More than half of the bamboo vipers captured in Tainan in the past few years were found in the city’s Sinhua District (新化), while other districts had smaller catches or none at all. Every year, Tainan captures about 6,000 snakes which have made their way into people’s homes. Of the six major venomous snakes in Taiwan, the cobra, the many-banded krait, the brown-spotted pit viper and the bamboo viper are the most frequently captured. The high concentration of bamboo vipers captured in Sinhua District is puzzling. Tainan Agriculture Bureau Forestry and Nature Conservation Division head Chu Chien-ming (朱健明) earlier this week said that the
The Chinese Nationalist Party (KMT) caucus yesterday said it opposes the introduction of migrant workers from India until a mechanism is in place to prevent workers from absconding. Minister of Labor Hung Sun-han (洪申翰) on Thursday told the Legislative Yuan that the first group of migrant workers from India could be introduced as early as this year, as part of a government program. The caucus’ opposition to the policy is based on the assessment that “the risk is too high,” KMT caucus secretary-general Lin Pei-hsiang (林沛祥) said. Taiwan has a serious and long-standing problem of migrant workers absconding from their contracts, indicating that
SPACE VETERAN: Kjell N. Lindgren, who helps lead NASA’s human spaceflight missions, has been on two expeditions on the ISS and has spent 311 days in space Taiwan-born US astronaut Kjell N. Lindgren is to visit Taiwan to promote technological partnerships through one of the programs organized by the US for its 250th national anniversary. Lindgren would be in Taiwan from Tuesday to Saturday next week as part of the US Bureau of Educational and Cultural Affairs’ US Speaker Program, organized to celebrate the 250th anniversary of the signing of the Declaration of Independence, the American Institute in Taiwan (AIT) said in a statement yesterday. Lindgren plans to engage with key leaders across the nation “to advance cutting-edge technological partnerships and inspire the next generation of scientists and engineers,”
