Nutritional strategies for piglet
diets without zinc oxide
While there is no direct replacement, promotion of gut health and
immunity helps prevent diarrhea.

J

ust as for antibiotics, there is no one answer, or
additive, to replace zinc oxide in piglet diets.
Instead, there needs to be a greater understanding of the causes and contributing factors,
to diarrhea at weaning. Key areas of investigation
include the intestinal microflora, gut health, immunity and diet digestibility.
Diet formulation, including optimal enzyme additions, can have positive effects on gut health. The use
of additives including organic acids, fatty acids and
probiotics help to reduce pathogenic and increase
beneficial bacteria within the intestine.

The problem with zinc oxide
While the exact mode of action of zinc oxide in piglet
diets in unknown, the reason for its addition is clear. It
is used to prevent diarrhea in piglets at weaning and, as
such, it's been added at high levels in most pig starter
diets for many years.
However, the EU had decided to ban its use from
2022, due to animal and public health, as well as environmental concerns. Some of the zinc fed to piglets
accumulates in their vital organs, potentially affecting
health and performance; while the rest is excreted
where is can pollute soil and water.
