Aim for zero: FREQUENTLY ASKED QUESTIONS and answers about going zinc free
In the past, farmers could use medicated zinc to cope with weaning stressors: limited colostrum availability, a still-developing gut microbiome, risk of toxins, exposure to pathogens, and a prevalence of free radicals to name a few. All these stressors could potentially have a huge impact on the health and performance of the piglets. However, this rearing method has come to an end in Europe and the rest of the world will likely follow. With this transition are many questions on how to support piglet health without medicated zinc. With years of experience raising piglets without medicated zinc, Earlyfeed provides detailed answers to 3 frequently asked questions within Europe.
1. How can we minimize weaning stress?
With changes in the environment and diet, piglets experience a lot of stress which will have a negative influence on the weaning period:
Common forms of stress around weaning
To minimize this weaning stress you have to minimize the degree of change. For example, to reduce the changes in environment, we advise to avoid excessive mixing of litters. Nowadays, the average size of the pen is designed so that it is almost impossible not to mix litters. Therefore, the Earlyfeed team advises the following:
By splitting piglets into different groups, you are able to feed them according to their needs. For example, by sorting, you can feed the smaller piglets extra in a separate bowl. This will ensure all piglets are eating enough without having the hierarchy stress of heavier piglets present. This will pay off immediately (Figure 1).
2. Piglets are not eating in the farrowing crates. What should we do?
Several factors influence the eating behavior of piglets in the farrowing room. First, you should find out why the piglets are not eating. Good things to check include:
Within this question are many factors and your Earlyfeed expert can provide appropriate advice for your farm. A few answers to the above points include:
3. How can I encourage piglets to drink enough water?
Supporting many essential functions, water is a very important nutrient for weaned piglets. It helps with:
For the first three days post-weaning, proper water intake is desired above feed intake. This is because it is hard to have sufficient feed intake without water. A good way of thinking about the importance of water is by considering what it would be like to eat six salty crackers at once without drinking water. In general, the water-to-feed ratio the first-week post-weaning should be 4:1. This number should decline every week towards 3.2:1 in the fourth-week post-weaning and should be a 3:1 at the end of the nursery period (Figure 2).
To assure sufficient water intake post-weaning, check the following items:
|Piglets during lactation||0.3||0.5 – 1.0|
Each of these topics influences the water intake accordingly. To get to know more about the other influencing parameters on water intake, please contact with your local Earlyfeed expert. As we have successfully helped producers transition to a zinc-free environment, our Earlyfeed experts received plenty of questions on how to remove medicated zinc without increasing the use of antibiotics. In addition to the questions here, we also know many are struggling with the following question too:
