SUMMARY An account is given of the rearing of 74 out of 104 (71%) HYPAR (hysterectomy procured artificially reared) piglets to the age of eight weeks. The classical hysterectomy hood (Young and Underdahl 1953) was used; and the piglets spent approximately two weeks in a newly designed constant temperature air‐conditioned rearing chamber where 82.6% survived. Descriptions follow of the piglets' diet, the methods ensuring initial sterility, and the growth performance and feed conversion of the piglets from two to eight weeks. The heaviest losses occurred after removal from the rearing chamber. It is suggested that factors related to this are low body weight and evaporative cooling. If piglets weigh at least 5 lb before entering a free environment, and remain warm and dry, they are likely to survive.
