In the sweltering summer days, especially following periods of intense heat, the high temperatures not only alter the nutritional requirements of dairy cows but also lead to a significant drop in their feed intake. As a result, the levels of certain essential trace elements, including potassium, may become inadequate. This deficiency is further exacerbated by the fact that cows lose potassium through sweating, which can create a negative potassium balance in lactating cows. This imbalance disrupts normal metabolic processes, leading to reduced feed consumption and lower milk fat percentages, both of which are detrimental to productivity and cow health.
According to recent studies from international researchers, potassium should make up about 0.3% of a dairy cow’s diet. However, after 6 to 8 weeks of lactation, the cows’ feed intake often falls short of meeting these nutritional demands. With minimal nutritional reserves, it becomes necessary to supplement their diet with additional potassium. While the standard recommendation is 0.3% potassium in the diet, this amount should be increased during hot weather. Research shows that cows fed with 1.3% potassium during the summer have higher feed intakes and produce more milk compared to those receiving only 0.9%. Potassium carbonate or potassium chloride can be added to the feed to help mitigate the effects of heat stress, thereby improving feed consumption and maintaining milk production levels.
In addition to potassium supplements, potassium carbonate can be used as an alternative to sodium bicarbonate. It acts as a buffer in the rumen, helping to maintain optimal acidity levels. This promotes increased saliva production, enhances feed digestion and nutrient absorption, and helps prevent a decline in milk fat percentage. By incorporating these dietary adjustments, farmers can better support their dairy cows during the challenging summer months, ensuring both health and productivity remain stable.
