Iceland's horse farm industry is facing criticism over its practice of extracting PMSG hormone from the blood of pregnant mares, which is then used to improve the fertility of other animals like cows, sheep, and pigs. The country hosts around 119 blood farms, with nearly 5,400 mares bred for this purpose, a number that has tripled over the past decade. Critics, including animal welfare organizations, argue that the method is cruel and have shared a video evidence leading to a police investigation. Despite the allegations of poor practices, no ban on blood farms has been imposed, but stricter regulations were introduced in August to oversee the industry's operations.
