"Sexer" is a term that describes a professional who specializes in determining the gender of animals. While this word may be commonly used in the farming industry, it can be replaced with a variety of synonyms that may be more applicable in different contexts. For example, "gender specialist," "animal genderer," "sex identifier," and "sex discriminator" are all acceptable alternatives. Additionally, some people may refer to this role as a "livestock evaluator," "animal inspector," or "animal caretaker." Whatever you choose to call someone who specializes in determining the sex of animals, it is important to recognize the crucial role that they play in sustainable animal husbandry and farming practices.
