    Rumen Buffers
    Rumen acidosis is a metabolic disease of cattle. Like most metabolic diseases it is important to remember that for every cow that shows clinical signs, there will be several more which are affected sub-clinically.
    Acidosis is said to occur when the pH of the rumen falls to less than 5.5 (normal is 6.5 to 7.0). In many cases the pH can fall even lower. The fall in pH has two effects.
    Firstly, the rumen stops moving, becoming atonic. This depresses appetite and production.
    Stages of Acidosis, Rumenitis, and Liver Abscess Development
    Secondly, the change in acidity changes the rumen flora, with acid-producing bacteria taking over. They produce more acid, making the acidosis worse. The increased acid is then absorbed through the rumen wall, causing metabolic acidosis, which in severe cases can lead to shock and death.

    Why and When To Use TESYA PL
    Saliva is a natural buffer containing a mixture of salts including phosphates and bicarbonates. There are occasions when the buffering effect of saliva is challenged and the target pH fluctuates and cannot be maintained.
    It is obvious that in a situation of scarcity of this buffering agent, Lowers rumen pH and its contents will be acidic, which can lead to acidosis.
    ACIDOSIS – pH<5.8
    Low pH causes a decrease in activity of cellulolytic microorganisms, this leads to a reduction in the digestibility of the feed and reduction of food intake.
    TESYA PL  can help buffer rumen pH levels in the following situations:
    • High grain feeding
    • High moisture chopped forages
    • Ground and/or pelleted rations
    • With changes in feed and rations
    · In stressful situations: heat stress

    TESYA PL is a product of the action against acidosis. Provides all the buffering capabilities of sodium bicarbonate in a more soluble formula. It also includes calcium carbonate and magnesium oxide to assist in balancing rations for proper mineral levels, fumaric acid and yeast.
    TESYA PL regulates the pH of the rumen, effect on the activity of fiber digestive flora and increases the food intake. Is composed of  different buffer substances, which are complementary action. 
    The largest share in the preparation of sodium bicarbonate – the product most commonly used over the years in the fight against rumen acidosis due to the very high capacity of detoxifying. The buffering capabilities of sodium bicarbonate help stabilize rumen acids, increasing feed intake and improving rumen performance.
    Rumen buffers and  yeast supplements have completely different modes of action but are complimentary.
    Yeast Saccharomyces cerevisae, lifts rumen pH and stimulates growth and activity of rumen microbes increasing rumen fermentation rates, removing lactic acid and improving feed efficiency. Yeast is also a rich source of B vitamins and enzymes, and their cell walls are able to bind to toxins (DON, ZEA, OTA).
    Rumen buffers directly neutralize acids in the rumen and provides a stable pH for rumen microbes to thrive.
    Calcium carbonate and dolomitic limestone, actually have very little buffering activity within the range of pH encountered in the rumen. Others, like magnesium oxide, are not buffers at all but rather acid neutralizers. The difference is that buffers act to maintain a constant pH, whereas acid neutralizers can only elevate the pH as they absorb acid. Both effects typically are beneficial to the dairy cow, but the processes are different.

    Creates a favourable pH for cellulolytic bacteria in the rumen
    Reduced risk of rumen acidosis, leading to improved performance & feed efficiency
    Improved general health of high yielding dairy cows
    Improved Calcium : Phosphorous balance in feeding stuffs
    Good absorption
    Higher feed conversion efficiency
    Maintain optimum rumen pH

    Recommended feeding rates for cows in lactation:
    •          Prophylaxis – 50 gr animal/day
    •          Healing – 100 gr animal/day
