Final answer:
While Vitamin D is important for cow health, it is not the main prevention strategy for mastitis, which is largely managed by maintaining proper hygiene and milking routines. Additionally, though antibiotics can treat mastitis, overuse can contribute to resistance.
Step-by-step explanation:
The question addresses the prevention of mastitis, a disease in dairy cows, by suggesting the use of additional Vitamin D in their diet. Mastitis is not primarily a metabolic disease but an inflammatory response of the udder tissue, often due to bacterial infection. However, animal health can be influenced by nutritional status, including the availability of vitamins and other nutrients. Vitamin D plays a crucial role in the immune system and is necessary for the absorption of calcium, which is important for overall health and bone strength. While Vitamin D is beneficial to cows, it is not the main preventive strategy for mastitis; instead, proper hygiene, milking procedures, and cow comfort are generally the key measures. Antibiotics can also be used to treat bacterial infections that cause mastitis, but their excessive use can lead to antibiotic resistance.
