The term ‘Folklore husbandry’ has become a way of describing how animal care and some biological information can be handed-down from one source to another without supporting robust (or any) scientific evidence – success or failure by trial and error. While some successes from folklore husbandry arise, this still does not ensure that a practice can be either consistently performed or proven effective compared with other options. Accordingly, at best, folklore husbandry is speculative and unscientific. However, frequently folklore husbandry – perhaps more precisely regarded of as ‘arbitrary husbandry’; results in multifactorial harms, because poor information based on ignorance or supposition becomes adopted by one generation of carers after another - the normalization of bad practice. In this presentation, folklore husbandry, and some examples of it, will be discussed, and a novel approach to information standard raising will be presented to help avoid potential harms inherent to the arbitrary care of animals.
