Cows suffer greatly from high temperatures and humidity (heat stress), among other reasons because the digestion of fiber-rich feed in the rumen releases a lot of heat—similar to a biogas reactor. However, it is not really possible to switch a ruminant to a low-fiber ration, as rumen acidosis and a decline in feed intake would inevitably be the result.
Protected fats do not act in the rumen
Feeding protected fats to secure energy supply is a commonly used measure, but it only brings partial success. These fats have no function in the rumen, so heat production continues, even if the cow consumes less fiber. Supporting rumen function with live yeast is a good option to maintain feed intake while at the same time reducing heat stress on the animal.
Respiration rate decreases with live yeast Actisaf
To get rid of excess heat, cows increase their respiration rate. In a study from southern Brazil with lactating cows, it was shown that Actisaf® reduces heat production in the rumen. The THI during the 10-week trial period averaged 71.8, with a peak of 85.1.
The group receiving the live yeast Actisaf® in their diet consistently showed lower respiration rates—on average 15% less. This indicates that less heat was produced, meaning the cows were calmer and used less energy for breathing. Together with improved feed intake, this resulted in higher glucose levels in the blood plasma. Each liter of milk contains about 46 g of lactose. In the test group, the cows converted the nearly 10% increase in blood glucose into a 5% higher milk yield.
Start early with orgacell sc
Therefore, we recommend introducing a product with live yeast into the feeding regimen in good time, e.g. Therefore, we recommend introducing a product with live yeast into the feeding regimen in good time, e.g.
orgacell sc® mb or orgacell sc® 5/10, and increasing the daily dosage depending on weather conditions from 20 to 30 g in order to relieve the cows. The animals repay this with milk and better animal health. Live yeast – the turbo for rumen and metabolism!
