It has been over 29 years since the International Symposium on Equine Reproduction (ISER) was held in South America, in Caxambu, Brazil. In 2023, ISER returns to a continent and country which not only has the fourth largest equine herd in the world, with 5.5. million horses, but has a long standing history involving the breeding of equids. Horses, donkeys or mules are used for sport, leisure and work activities. Brazil and Argentina are also at the forefront of equine reproduction research, particularly assisted reproductive technologies such as embryo transfer, cloning, intracytoplasmic sperm injection and semen sexing. People in this vast continent are passionate about their horses and also know how to party, with music, dancing and delicious food all part of their unique culture.
