Why do we need to feed Minerals?

Feeding balanced mineral supplements to livestock in the tropics is crucial for ensuring optimal animal health, growth, reproduction, and overall productivity. The unique environmental conditions and challenges posed by the tropics can lead to deficiencies in essential minerals, which can have detrimental effects on livestock health and productivity. Let's delve into the importance of specific minerals, their roles, and the reasons animals need mineral supplements in the tropics:

Salt (Sodium and Chloride):

  • Salt is a vital mineral for maintaining proper hydration, electrolyte balance, and nerve function in animals.

  • In tropical climates, excessive sweating due to heat stress can lead to salt depletion, causing dehydration and reduced performance.


  • Phosphorus is essential for bone development, energy metabolism, and reproductive function.

  • In tropical areas, soils are often low in available phosphorus, which can result in skeletal abnormalities, poor growth, and reduced fertility in livestock.


  • Calcium is a key component of bones, teeth, and milk production. It also plays a role in muscle contraction and nerve transmission.

  • Deficiency in calcium can lead to weak bones, milk fever (hypocalcemia), and reproductive problems in animals.


  • Magnesium is vital for muscle and nerve function, as well as enzyme activity.

  • In tropical regions, magnesium deficiency can result from low dietary intake or high potassium content in forages, leading to conditions like grass tetany or hypomagnesemia.

Copper and Zinc:

  • Copper is important for iron utilization, enzyme function, and coat pigmentation. Zinc is involved in immune function, wound healing, and growth.

  • Both minerals are often deficient in tropical soils, which can lead to poor growth, anemia, and compromised immune systems in livestock.

Reasons animals need mineral supplements in the tropics:

  1. Inadequate Soil Mineral Content: Many tropical soils are naturally deficient in essential minerals due to leaching, weathering, and other geological processes. This deficiency is then reflected in the plants grown on these soils, which subsequently lack the necessary minerals for livestock.

  2. Forage Composition: Forages, a primary food source for livestock, may have imbalanced mineral content, especially in phosphorus, calcium, magnesium, copper, and zinc. Animals consuming forages deficient in these minerals will require supplements to meet their nutritional needs.

  3. Heat Stress and Sweating: High temperatures and humidity in the tropics can cause animals to sweat excessively. Sweating not only leads to water loss but also results in the loss of essential minerals, particularly salt. These losses must be replenished through mineral supplementation.

  4. Increased Nutrient Demands: Livestock in tropical environments often face increased nutrient demands due to the stress of heat, humidity, and disease challenges. Providing adequate mineral supplementation helps meet these elevated nutritional requirements.

  5. Reproductive and Growth Demands: Reproduction and growth are energy-intensive processes that demand optimal mineral intake. Deficiencies in minerals like calcium, phosphorus, and zinc can result in reproductive disorders and stunted growth.

Balanced mineral supplementation is essential for overcoming soil deficiencies, promoting proper growth, reproduction, and overall animal health, and mitigating the negative effects of heat stress. If you need more information please contact us for a consult.
