1. Selenium Supplementation
Selenium and vitamin E are essential nutrients that help protect animals from various diseases, especially in dairy cows. A deficiency in these nutrients can significantly weaken a cow's ability to fight off infections, particularly mastitis. To support immune function, it is recommended to provide 1000 IU of vitamin E and 2 mg of selenium per day to young cows 60 days before calving. During lactation, the daily intake should be reduced to 600–800 IU of vitamin E and 2 mg of selenium. Studies have shown that this supplementation reduces the infection rate during calving by 42%, lowers the incidence of clinical mastitis in early lactation by 57%, decreases the overall lactation incidence by 32%, and shortens the duration of disease by 40–50%. These improvements highlight the importance of maintaining proper selenium and vitamin E levels for better herd health.2. Zinc Supplementation
Zinc is a crucial mineral that supports immune function and plays a role in many enzymatic reactions involved in inflammation and infection. Adding organic zinc, such as zinc methionine, to dairy cow diets has been shown to improve milk production and reduce the number of somatic cells in milk, which is an indicator of udder health. Research indicates that feeding 25 mg/kg of zinc methionine can lower the somatic cell count by 50% and reduce the incidence of mastitis by 32.6%. Additionally, this supplementation leads to increased milk yield, making it a valuable strategy for improving both productivity and udder health in dairy cattle.3. Copper Supplementation
Copper is vital for the activity of several enzymes involved in metabolism and immunity. When copper levels are insufficient, cows become more susceptible to infections, and inflammatory responses may worsen, leading to higher somatic cell counts in milk. In one study, young cows were divided into two groups: one receiving a basal diet with 6–7 mg/kg of copper, and the other receiving an additional 20 mg/kg of copper. The group with extra copper showed a 22% reduction in the number of udders infected by major pathogens. It's important to note that copper absorption can be hindered by high levels of sulfur, molybdenum, zinc, or iron in the diet, so careful formulation of feed is necessary to ensure optimal copper utilization.Frozen Shrimp,Frozen Cooked Shrimp,Fresh Frozen Shrimp,Red Shrimp Seafood
