Watch: How these farmers built up a good mineral balance in their cattle

Minerals and vitamins, while accounting for a small percentage of the dietary requirements for cattle, play a crucial role in their overall health and function. These nutrients are essential for processes such as bone development, muscle contractions, and maintaining a good nervous system and immune function. A lack of proper mineral balance can lead to compromised growth and fertility, which can significantly impact a farmer's bottom line.

In the face of continuously rising input costs, it is vital for farmers to avoid unnecessary expenses. One way to achieve this is by ensuring their cattle receive adequate minerals through various dietary sources. These sources include forages, concentrate feedstuffs, mineral supplements, and water.

Mineral requirements for cattle are typically divided into macrominerals and microminerals (trace elements). Macromineral requirements are usually expressed as a percentage of the total diet, while micromineral requirements are generally expressed in milligrams per kilogram (mg/kg) or parts per million (ppm). It is essential to understand that there are numerous mineral interactions that can lead to minerals either tying up or making other mineral elements unavailable, causing imbalances.

Mineral imbalances, whether toxicities or deficiencies, can trigger nutritional disorders in animals. Common examples include grass tetany, urinary calculi, white muscle disease, and milk fever in cattle. While these disorders may sometimes present with dramatic signs, mineral imbalances are often unnoticed or overlooked because they may only cause subclinical signs.

Farmers should be on the lookout for identifiable signs of mineral or vitamin shortages or imbalances in their animals. These signs can include loss of hair around the eyes and back, discolouration of the coat, ill-thrift, infertility, swelling of the joints, scour, poor conversion, and growth below the animal's genetic potential. Less obvious signs may include reduced productivity or conversion rates in both cattle and sheep, ultimately leading to increased costs for the farmer.

To address these challenges, farmers should consider mineral supplementation at pasture. This approach can help ensure that their cattle receive the necessary minerals to maintain optimal health and productivity. By doing so, farmers can avoid the additional costs associated with treating mineral-related disorders and improve overall animal performance.

In conclusion, maintaining a good mineral balance in cattle is essential for their health and productivity. By understanding the importance of minerals and vitamins, as well as the potential consequences of imbalances, farmers can take proactive steps to ensure their animals receive the necessary nutrients. This may involve supplementing mineral intake, particularly when grazing on pastures that may not provide sufficient levels of these vital nutrients. By doing so, farmers can help prevent costly health issues and improve the overall efficiency of their operations.
