Many studies in cattle have aimed at simplifying the administration of FSH, which, because of its short biological half-life, generally involves a four-day, twice-daily injection schedule. Such simplications can be important in terms of animal welfare and minimizing stress, as well as lowering labor costs on the farm. Beef cattle, for example, are less accustomed to handling than dairy cows and are often much less docile. Conventional superovulation protocols developed for domestic cattle often prove less efficient when applied to indigenous breeds of cattle or nondomestic ungulate species, due to the stress of handling.
