Butyric Acid

Fight Butyric acid bacteria from silage until cheese.
There are currently a lot of questions coming from companies regarding Butyric acid asking on what they can do. Here are some answers and advice for you. Not the butyric acid bacteria, but rather the acid tracks are the problem. The prevention is located in the ensiling management and hygiene during milking.


What is Butyric Acid?
Butyric acid is a volatile fatty acid with a pungent smell (sweaty feet) and unpleasant taste. Butyric acid bacteria are spore-forming bacteria that produce acid in poorly and moderately conserved grass and maize silage. Spores are bacteria in a sort of state of rest that are very resistant to drought, heat and other extreme conditions. That way they can survive and germinate under favorable conditions into harmful bacteria. Through litter, manure, but especially poor silage, butyric acid bacteria can end up in the milk. In contrast to the butyric acid bacteria, the spores survive the pasteurization of the milk and can then cause problems in the manufacture of cheese. Silages that contain Butyric acid are silages which contain less than 35% dry matter (often damp silages). Often these are silages with a high pH, which have been mown later. Most of the time it is about silages with high yield that have been ensiled too quickly due to time pressure.
 
Prevent Butyric acid in the milk
Contamination of milk by the butyric acid bacterium comes from the outside. This means that you can prevent contamination by optimizing hygiene around milking. In addition, we advice to cut down the amount of contaminated feed being mixed through the normal feed. Another good advice is to feed the sides of the silage to the calves. In short, reduce the proportion of contaminated silages and ensure proper hygiene around milking.
 
Hygiene around milking

Each month, the (tank)milk is tested for acid tracks. The quality of grass- and maize silages determine the number of spores in the milk. The base is the preparation of a good grass and maize silage, in which all tips for a good preservation must be followed. When ensiling wet grass, it is important to use a silage additive. One more important thing; also adjust the shaker properly which minimizes sand coming in the silage. Make sure to cover the silage immediately after ensiling,
 
Hygienic practices in the stable and milking parlor are important.
 
Some tips

Keep cubicles clean. In cubicles use Stal Strooi Plus. (The appropriate and affordable hygiene agent for cubicles). Make sure udders are shaven and clean (preferably burn with Udder Hair Remover Mobile Dura).
 
Hygiene before and during the milking process:
• Preferably use paper udder towels (Maxi Udderpaper is ideal to this purpose). Maxi Udderpaper meets the Nutrition Quality rules. Maxi Udder Paper is not wiping paper but specifically designed for optimal cleaning of the teats, absorbing dirt and milk.
• If you use cotton towels you can use Dip / Spray product.
• To dip or spray also use Dip / Spray product.
• Affoid losing grip on the teat.
• Keep milk claw and teat cups clean.
