In the heart of South Korea's dairy industry, a stark reality remains hidden from many consumers: cows are often restrained in shackle lines, a practice that severely impacts their welfare. Despite the growing demand for transparency and ethical practices, legal loopholes persist, enabling this controversial method to continue.
Shackle lines are a common sight in South Korean dairy farms, with an estimated 70% of farms using this method (Korea Rural Economic Institute, 2022). While some argue that it prevents damage to facilities and improves milk production, the animal welfare implications are undeniable.

The Legal Loopholes
South Korea's Animal Protection Act prohibits the 'cruel treatment of animals,' but shackle lines remain legal due to a lack of specific regulations. Dairy farmers exploit this loophole, arguing that the practice is necessary for maintaining production.
The Impact on Animal Welfare
Shackle lines limit cows' ability to move freely, causing stress and frustrating their natural behaviors. This restriction can lead to injuries, such as swollen legs and hock damage (The Veterinarian, 2020). Moreover, limited movement hinders cows' ability to lie down comfortably, causing further discomfort.
“Shackle lines restrict cows' natural behavior, causing stress and leading to various health issues. It's high time we address this concern and improve the welfare of these animals.”
| System | Milk Yield (kg/cow/year) | Lameness (%) | Hock Injury (%) |
|---|---|---|---|
| Stall-based (including shackle lines) | 7,180 | 36.3 | 22.1 |
| Pasture-based | 5,400 | 13.3 | 5.7 |
