Are your cows suffering from rumen acidosis? Read all about what you can do about it!

This common problem in cows occurs when the pH in the cow’s rumen drops below 5.6 for several hours.This drop disrupts the normal functioning of rumen flora, leading to reduced feed intake and negative effects on milk production.

How does rumen acidosis occur in cows?

Penile acidosis is caused by an excess of volatile fatty acids in the rumen, which lowers the pH.This can occur in rations with high energy density, rapidly digestible carbohydrates, or a lack of structure in the feed.In particular, forages with high organic matter digestibility increase the risk of rumen acidosis.

How do you recognize rumen acidosis in cows?

It is important to recognize rumen acidosis early.Watch for the following symptoms:

• Cows often lie with their heads in their flanks.
• Fewer than 7 in 10 resting cows are ruminating.
• Reduced rumen activity (normally 1 to 2 rumen contractions per minute).
• Irregular ruminations (less than 55 or more than 80 ruminations per minute).
• Reduced feed intake, insufficient rumen filling, and thin or inconsistent manure.
• Other indicators include a decrease in fat content in milk, claw fat, dull hair coat, and undigested feed residue in manure.

How do you prevent rumen acidosis in cows?

To prevent rumen acidosis in cattle, it is important to keep the PH in the rumen stable.Some preventive measures are:

• Always provide available and palatable feed to avoid large fluctuations in feed intake.
• Add sufficient structure to the ration and avoid selection by mixing the feed well.
• Use crushed grains for more gradual digestion.
• Provide plenty of fresh water and gradually accustom cows to changes in their rations.
• Provide adequate feeding space and avoid overcrowding.
• Consider adding sodium bicarbonate and magnesium oxide to the ration to strengthen rumen buffer.

Penile acidosis is common in dairy cows, with a prevalence of 10-20%.Given that the cost of a single case adds up quickly, excluding replacement and veterinarian costs, prevention is essential.
