EXTRA FOCUS ON HYGIENE, DRYING OUT AND BEDDING FOR ZINC-FREE WEANING
The objective of washing and disinfecting is to keep the level of infection low and to give the pigs the best possible welfare and growth conditions. Infection levels can be reduced in the herd by including hygiene in the daily routines, and systematic cleaning and disinfection of pens before penning/transfer of animals. Our experience shows that strictly following a plan for cleaning, disinfection and drying out pens is key when phasing out medical zinc oxide.
Soap and disinfection
The bacteria form a biofilm on surfaces in order to protect themselves. The film consists of dirt from the pen environment and cannot be dissolved and removed by water alone. Soap does not kill bacteria, but does dissolve and remove the biofilm allowing disinfectant to do its job against bacteria, which means both products have to be used in a subsequent combination.
Bacteria can thrive particularly well under mats and other places that are warm and damp. It’s therefore very important to lift and remove all mats. There are often mats in the holes of farrowing houses/sections, and there can also be weight relief mats under the sow. If they're not lifted and removed, there is a major risk of bacteria multiplying, which can lead to increased frequency of diarrhoea, umbilical hernia and arthritis in weaners.
The use of soap and disinfection can give a better health status and increase in production, but it requires a correct usage of these substances according to their direction of use. If the products are used incorrectly, disinfectant failure is often seen. We recommend an expertise guidance in the choice and use of soap and disinfectants to avoid it rapidly becoming an expensive experience.
Bedding in the corner holes with full floor gives to the pigs a dry, warm and healthy environment. When choosing bedding, it’s important that it’s not too sharp or rough, which can accidentally scratch weaners allowing bacteria to get in and may for example cause arthritis. A good tip is rubbing the back of your hand on the bedding to determine how scratchy it is.
In Vilomix we recommend a mix of Agrosan Dry Out® - a dry disinfection product invented in Denmark, tested by recognized international laboratories and used worldwide due to its documented effect on the most common bacteria and fungi spores - and Vilostrø (heat-treated quality straw) using a ratio of 1:1 for excellent control of flora in the bottom of pens.
