acidosis in dairy cattle

I think Dr.Usman is asking about the Acidosis caused by accidental acess of the animal to the grains or grain overfeeding in days near to Eid-ul-Azha.. Now a days many such cases will come.
How can we treat them?

One of the differential advantages of this product against buffers is that it is not focused on buffering the ruminal liquid, but increasing the uptake of lactic acid by lactic acid utilzers bacteria of the rumen.

As a consequence, more propionic acid is produced, and then, more energy is taken from the ration.

This, along with the increase in the digestibility of the diet that this product provokes, increase feed efficiency at important levels.

Furthermore, it can be used along with the products that Roberto is talking about, since their mode of action and pathway works in parallel.

Acute ruminal acidosis cannot be prevented or cured with buffers or probiotics! As mentioned by one of the colleagues, acute ruminal acidosis is often the result of (accidental) grain overload. I learned that treating acute ruminal acidosis by oral delivery of buffers is contra-indicated: it may resume the fermentation of not-yet degraded carbohydrates still present in the rumen, thereby increasing lactic acid production. Ending ruminal fermentation by antibiotics is more favourable in those conditions, but this requires the collection of ruminal digesta (from donor animals / at slaughter house) to re-establish a healthy, functional ruminal population. Buffer solutions should be given parenteral.

Subacute ruminal acidosis (SARA) as a result of a low ratio structural:non-structural carbohydrates in the diet can be prevented by buffers or probiotics. However, buffers reduce the palatibilty of the ration and probiotics are relaively expensive. The best way for SARA prevention is to increase the ratio between intact structural carbohydrates (forages) and non-structural carbohydrates (grains). If this leads to a reduction in energy intake, consider to feed more fibre ad lib and withdraw the residues regularly. This will allow the high-producing animals to select the most nutritious parts of the diet. Good luck!

Taking into account the issues we ar discussing, I really think that increasing the conversion of lactic acid into propionic acid by means of lactic acid utilizers bacteria is key. As probiotics are expensive, malate supplementation is a great solution, since this compound increases the capacity of Selenomonas ruminantium (lactic acid utilizer) to convert lactic acid into propionic acid. When given in forms of salts, their effects are better.

The key to this whole issue is management. With the correct management, most treatments can be avoided.
Correct balance diet with addition of key natural ingredients like live yeast, probiotics, and yeast extracts. Saccharomyces cerevisiae, Aspergillus oryzae, Bacillus subtilis, Lactobacillus acidophilus are good choices. I believe that good management and good nutrition, would control most of the acidosis problems from surfacing. I love to stay away from most chemicals, even though is what the trends call for in today's inefficient and anti-environmentally practice of FACTORY FARMING. "An ounce of prevention is worth a pound of cure!"

Hello, thanks for your comment
One question: what Peri-biotic for control acidosis?
Thank you very much.

In my experience, ruminal acidosis is always a combination of several factors. Fundamental mistake is nutritional management - lack of structure TMR, or a different length of TMR particle (grain, silage, hay or straw long), or high dry matter TMR where cows can be very easily separated.
The second mistake is the lack of piling-up of fresh TMR. Another factor is the welfare of the animals in their pens - the social struggles, enough space, access to feed, narrow passages in pens, plenty of water, etc.
