The Federation was formed along the lines of the European Federation at a meeting in Singapore in 1981, following initiatives mainly by the Australian, Japanese, Korean, Malaysian and New Zealand branches. The first President was Mr Noel Robertson (NZ) and the first Secretary-Treasurer Mr Milton Watt (NZ).
The first Regional Seminar under the Federation's name was held in Adelaide, Australia, in conjunction with the Fifth Australasian Poultry and Stock Feed Convention. Subsequent Federation Seminars and Conferences are listed below. At the meeting in Seoul (Korea) in 1993 the name of the Federation was changed to Asian Pacific.
The Federation follows the practice of changing the President and Secretary-Treasurer every four years and ensuring the rotation of these office-bearers among the active branches of the Federation. These officers are listed below.
The following branches of the WPSA are now members of the Federation: Australia, Bangladesh, China, Fiji, India, Indonesia, Iran, Japan, Korea, Malaysia, Nepal, New Zealand, Pakistan, Papua New Guinea, Philippines, Singapore, Sri Lanka, Taiwan, Thailand and Vietnam.
