Keeping cows calm and productive in hot, humid summers
Effect of high temperatures on cows
Heat stress in cattle occurs when the animals generate and absorb more heat than they can easily get rid of by respiration. When surrounding temperature increases and in combination with increased humidity, cows tend to reduce feed intake and increase water consumption to regulate body temperature. The feed fed to cows is also impacting heat production. When feed is broken down in the rumen, heat is produced and in combination with increased surrounding temperature, rumen temperature increases, and feed intake is negatively impacted. Irregular feed intake due to heat inevitably leads to a high variability in rumen pH and risk of acidosis and consequently decreased productivity.
CoolFoss
Dairy cows suffering from heat stress benefit from CoolFoss by maintaining normal ruminant functions. The product is a blend of essential oils combined containing pre- and probiotics. Cows fed CoolFoss improve performance and increase milk yield during hot and humid temperatures. The cows spend more time lying and ruminating consequently ease the variation in rumen temperature and pH.
