Rumen buffering prevents summer suffering

Also dairy cattle can be affected by high summer temperatures. A number of years ago Pre-Mervo developed MERVIT® BUFFER+ as an antidote for this purpose. This reduces the chance of rumen acidification and reduces the negative impact of heat stress. MERVIT BUFFER+ contains a number of substances, including sodium bicarbonate and live yeasts, and can be fed as a supplement with another MERVIT Mineral Mix.

Cows become less active due to the high outside temperatures and consequently reduce their intake of roughage. However the quantity of feed concentrates often stays the same. As a result of this the cow has to deal with a higher (average) share of rapidly fermentable carbohydrates in her ration. This results in rumen acidification. MERVIT BUFFER+ reduces the chances of rumen acidification. In the event of heat stress, there is also an increase in the release of CO2 via the respiration. This results in a lower pH value of the blood which in turn is compensated through the additional absorption of bicarbonate. The additional quantity of bicarbonate is then at the expense of the quantity that would normally be channelled to the rumen and there is therefore a chance of rumen acidification through this mechanism as well.
