Alternative to zinc oxide in piglet diets
For a long time, providing zinc oxide in piglet diets was one of the ways to control diarrhoea-related problems in just weaned piglets. The upcoming change in legislation, which puts a limitation to the use of zinc oxide, asks for a new way of thinking since there is no single additive which can effectively replace added zinc. Successfully replacing zinc oxide in piglet diets asks for a different way of working: management, housing, climate, animal health status, it all plays a role. In this article we will focus on the role of feed and on Denkavit’s alternative to zinc oxide.
EU-ban on extended dosage of zinc oxide in piglet diets
Starting June 2022, the use of extended levels of zinc oxide as a veterinary medicinal product (above legal limitation of 150 ppm of zinc from zinc oxide or other sources) in piglet diets will be banned in the European Union. In some countries in Europe this was already earlier implemented. Also outside the EU (China, Korea, Canada) legislation gradually starts to shift in the direction of lower allowed levels of zinc as a feed additive.
How to successfully replace zinc oxide in piglet diets?
As mentioned before there is not one additive which successfully replaces added zinc oxide. Since zinc oxide is often used to control diarrhoea-related problems in just weaned piglets it’s key to wean healthy, vital, uniform litters with high weaning weights. However Denkavit developed a concept to assist you in making the transition to replace antibiotics and zinc oxide.
Under natural circumstances weaning is a gradual process in which piglets slowly switch from milk to dry feed. In current piglet production practice however, piglets are weaned relatively early and abruptly, at times without having sufficiently adapted to consume and digest dry feed before weaning. This will lead to very challenging and stressful situations for just weaned piglets. The preparation for a smooth transition around weaning starts already in the suckling period by maximing feed intake before weaning.
Preparation for weaning starts in the suckling period
Feeding piglet milk
Feeding piglet milk is a good way to increase feed intake before weaning. Read more about the effects of feeding piglet milk in the suckling phase and the results after weaning.
R&D trials performed at the Pig Farm, part of our DenkaFarm Innovation Centre, demonstrate that the application of creep feed is essential to prepare piglets for weaning. It leads to higher weaning weights and more is important that the piglets keep eating after weaning. Research demonstrates that the feed intake in the first four days after weaning was significantly lower for the piglets that received no creep feed compared to the two groups that did receive creep feed. Piglets who received creep feed continued to show significantly higher growth after weaning and higher weaning weights at start of the fattening period. In figure 1 you can see the trial results until day 63, group A was the group who received no prestarter whereas group B (Top Wean) and group C (Mellow Go) both received a luxurious prestarter.
Denkavit Safe Start Concept
Over the past decade Denkavit has performed multiple trials to investigate the effect of a different approach to transition diets for piglets around weaning, developing our Denkapig Safe Start Concept, known as our Safe Concept, this approach is characterised by:
- Based upon low crude protein formulation principles- selecting high-digestible protein sources
- Very high quality and processing of major materials
- Carefully selected package of functional additives
The Denkavit Safe Start Concept has been tested by the independent Schothorst Feed Research. In this trial our concept is tested against a control group (no added zinc oxide) and a group with 2500 ppm zinc from extra added zinc oxide.
Zinc Smart, what does Denkavit provide?
The Denkavit Safe Start Concept assists farmers and feed companies a complete approach from birth until 25 – 30 kg bodyweight. Our concept includes both complete feeds as well as concentrates to support the farmer in rearing piglets without extra added zinc oxide. Our approach is based upon of years of knowledge and is supported with tailor-made advise and formulation for your situation by our colleagues.
