The pharmacological use of zinc oxide (2,500-3,000 ppm ZnO) is widely accepted as an efficient means of controlling post-weaning diarrhoea (PWD) in piglets and is being used worldwide as an alternative to antibiotics (Mullan et al. 1995). However, the strategy is criticized because high levels of zinc are excreted into the environment through the effiuent system. Recently, a microencapsulated zinc oxide (ME-ZnO) product (Shield Zn®, CTC Bio Inc., South Korea) claimed to reduce PWD while at a reduced concentration of ZnO of 1OOppm. The ME-ZnO was evaluated relative to ZnO to assess its efficacy in controlling PWD. The hypothesis tested was that inclusion of MEZnO will efficiently control PWD and reduce faecal zinc excretion.
