- The ban on therapeutic levels of zinc oxide in piglet diets could result in losses of up to €1,080 million/year for the EU pig industry.
- Estimated losses of €4.15/pig/year due to higher mortality and reduced daily weight gain.
- Replacement of therapeutic levels of zinc oxide with pHorce resulted in an increase in final body weight gain of 1.67kg (p<0.05) at 49 days.
- Zinc is routinely used to control post-weaning scours but has been linked to environmental pollution and antibiotic resistance in some bacteria, such as MRSA (Yazdankhah et al., 2014).
- The European commission has banned pharmacological levels of zinc (>150ppm) in piglet diets by 2022.
Anpario have conducted a trial in weaning piglets at the University of Manitoba, Canada. Piglets were randomly allocated to treatment diets at weaning for a duration of 28 days and balanced for litter origin, gender and weight. Eight days post weaning (29 days of age), piglets were orally challenged with E. coli* (strain K88+). Animals had access to feed and water ad-libitum. Body weight and feed intake was measured weekly and all data was evaluated using ANOVA and Tukey’s t-test for pairwise differences.

||Zinc Oxide 3kg/MT|
- An increase of 41g/day in ADG was observed when fed pHorce or zinc oxide when compared with feeding the control.
- A significant (p<0.05) improvement of 1.67kg in final body weight (D28) was achieved in the pHorce treatment vs control. FCR was maintained.
- This study demonstrated that therapeutic zinc oxide can be replaced with pHorce at 3kg/t and provide an economic saving.
