Acid Buf

  • Contains a unique blend of rumen buffers
  • Helps to prevent rumen acidosis
  • Acidosis likely to be a particular problem on farm with high levels of cereal and certain forages
  • Helps to improve dry matter intake and rumen function

Rumen Acidosis (SARA) & Nutri-LINK Acid Buf

Dairy cows are unique among farm animals in the amount of acid produced in their digestive tract and found in their commonly consumed feeds. Each time dairy cows feed, they can expose themselves to acid over supply situations in the rumen from several sources such as silages, straights, concentrates and other potential high acid based ingredients.

The acid challenge is also dependent on the speed of the fermentation process that occurs in the rumen, as demonstrated in the simple chart below:

This acid can be present in the feed when consumed, or can be generated from the feed during fermentation and digestion. For example, maize silage ferments during storage, yielding a pH around 4, grass silages may have a pH of 3.8 or less. Their acid load content can be very high. Other feeds fed such as cereal based raw materials, moist bi-products, also have a high lactic acid loading in the rumen. Excess lactic acid causes acidosis if not correctly managed through the diet fed.

The Signs of Acidosis

  • Limited cud chewing and the presence of cud balls in the yard
  • Variable dry matter/daily feed intakes
  • Foamy, gaseous, mucosal dung
  • Variable dung consistency
  • Undigested grain and forage in dung
  • Restless cows
  • Sore Feet leading to laminitis in severe cases

The Role of Saliva

Saliva is a natural buffer containing a mixture of salts including phosphates and bicarbonates. Saliva is produced and swallowed during cud-chewing.  High-fibre diets that encourage cud-chewing also promote substantial production of saliva and mineral related buffers, which provides a greater protection to the rumen against acid challenges.  If a cow receives adequate long-stemmed fibre (e.g. straw), even when consuming a high-grain diet, she is better equipped to neutralize the significant acid production likely to occur during digestion of grain.  But there are occasions when the buffering effect of saliva is challenged, the target pH fluctuates to dangerous levels, these include:

  • Feeding wet, high lactic acid silage
  • Feeding finely chopped forages resulting in reduced saliva production and rumination
  • Feeding starch-rich, rapidly fermentable concentrates when fed in large quantities at one time

The acid load presented to the dairy cow through the diet’s inherent acid content, as well as digestion-related acid production, is large enough to cause significant health problems, starting with acidosis.

Get Grass Silage Analysed

Some of this years grass silage analyses indicate a challenge to the rumen stability and the potential acid overload. The key areas to discuss with your feed advisor/nutritionist are detailed below. If changing silage clamps, ensure the change occurs over 2 – 3 day period so that the rumen is given an opportunity to readjust to the forage fed. Dairy cows are like me - they hate change!

Maize silage also contains high levels of starch which may have a negative impact on rumen pH.

Low dry matter, low pH,  high PAL (Potential Acid Load), low RSV (Rumen Stability Value), high sugar content and high lactic acid are all factors that have a potential impact on Rumen pH.

Effects on the Rumen

  • As pH falls below 6.0, fibre-digesting microbes become less and less active.

  • In addition, sustained low pH can actually erode the rumen lining.

  • This, in turn, makes the cow more susceptible to liver abscesses. In response to bacterial invasion, dilation of blood vessels in hoof tissue increases the likelihood that laminitis may develop.

 The Link Between Diet & Performance

Sub-Acute Ruminal Acidosis has now become one of the most common problems on most dairy farms. Surveys suggest that over 20% of all cows suffer from a low rumen pH which is likely to be causing a whole host of problems including decreased yield, reduced intake, loose dung, undigested grain passing through, loss of condition and reduced fertility.  Using Acid Buf is the most effective way to combat the problem and help maintain a healthy rumen by neutralizing the excess acid.

Benefits of Feeding Acid Buf

  • Acid Buf buffers the rumen and not just the silage

  • Over 2.5 times the buffering capacity of sodium bicarbonate

  • Unique honeycomb structure increases surface area

  • Slow release buffer

  • Completely natural product

  • Helps reduces problems with acidosis

  • Helps stop cows “throwing” their cud

Acid Buf is considered an essential inclusion in the majority of lactating TMR diets now due to the increased problem of Sub Acute Ruminal Acidosis.  Can you really afford to not use Acid Buf? Supplied in 25 kilo bags, Acid Buf is available through the Mineral Line on 01278 420481 or your local Mole Valley Farmers representative at competitive prices.TMR Farmpacks Alternatively we have the ability to blend Acid Buf with your powdered mineral supplement to produce a Nutri-LINK TMR FarmPack – to give you the added convenience of a 1 product solution which will be manufactured to your requirements at our own mineral plant at Bridgwater in Somerset – easy feeding technology from the Mineral Team!

 Feeding Rates of Acid Buf

Acid Buf needs to be thoroughly mixed into the TMR mix to extract its full buffering potential.
