In the hot summer days, especially after the volcanic days, the hot and hot weather not only changes the nutritional needs of dairy cows, but also leads to a decrease in the intake of dairy cows. As a result, the intake of certain trace elements by the cows during this season is insufficient. Causes insufficient absorption of potassium. In addition, potassium in dairy cows will be excreted with the sweating of dairy cows, so the potassium metabolism of lactating dairy cows will be negatively balanced, affecting the normal metabolism of dairy cows, reducing the intake of dairy cows and the milk fat percentage. Falling and other hazards. According to the research data of foreign researchers in recent years, potassium should account for 0.3% of the dairy cow's diet. The feed intake of dairy cows after 6-8 weeks of production generally cannot meet the nutritional needs of dairy cows at this stage. Nutritional savings are minimal, so it is necessary to supplement cows with a certain amount of potassium at this time. According to the cow's feeding regulations, the amount of potassium in the diet of each lactating dairy cow accounts for 0.3%, but when the weather is hot, the actual feeding to dairy cows should be higher than this level. According to literature data, during the hot summer season, cows fed with 1.3% potassium had higher intakes than cows with 0.9% potassium in the diet, and milk production was also high. Potassium carbonate or potassium chloride may be added to the feed. With the addition of potassium supplementation, the reduction in feed intake and the decrease in lactation levels caused by heat stress during the summer heat will be significantly improved and alleviated. In addition to potassium supplements, potassium carbonate can be added in addition to potassium supplements, which is comparable to sodium bicarbonate. Potassium carbonate, a buffer in dairy cows' diets, will help maintain proper acidity in the rumen of dairy cows. The environment increases the saliva secretion of dairy cows, improves the digestion and utilization of feed for dairy cows, and also has the function of preventing dairy cows from decreasing their milk fat percentage.
