Animal Nutrition: The Vital Importance of Salt Blocks and Bricks


We often need to pay more attention to the significance of salt blocks in animal nutrition and husbandry despite their crucial role in animal nutrition. These seemingly unremarkable salt bricks are essential for maintaining the well-being and health of different livestock animals. A salt lick for cattle is crucial in ecosystems with low nutrient availability. Harsh weather conditions uncover the salty mineral deposits, attracting animals to obtain the essential nutrients they require. This article will explore the salt blocks’ composition, their significance in animal nutrition, and the advantages they provide to ensure our companion animals’ optimal health.

Understanding the Fundamentals Salt Blocks and Bricks

We put salt blocks or salt bricks, also called salt licks, in pastures, stalls, and barns to allow animals to lick on them. These salt bricks consist mainly of Sodium Chloride (NaCl) but may also have small amounts of trace minerals like calcium, potassium, and magnesium. These minerals play a significant role in different physiological processes in the animals.

The Importance of Licking Salt Blocks for Animals

According to popular belief, some animals can identify calcium by licking salt. Lactating cows, for example, are highly susceptible to salt depletion and require daily doses of salt to produce milk containing adequate amounts of chloride and sodium. Wild animals often frequent salt springs or salt deposits, commonly called salt licks, to obtain essential nutrients by licking salt. Since all animals require salt, natural salt licks are popular congregating spots for animals.

All animals require salt as an essential nutrient to maintain optimal bodily functions. Salt plays a crucial role in this regard. The following are some of the causes why animals need to include salt in their food:

  1. Electrolytes such as chloride and sodium ions regulate the fluids’ balance within the animals' cells. This crucial balance is necessary for muscle contraction, nerve function, and overall well-being.
  2. It is not possible for animals to consume water to regulate body temperature and digestion; salt helps stimulate their thirst.
  3. Salt is crucial in nutrient absorption, such as calcium, magnesium, and phosphorus.
  4. Salt stimulates appetite by improving the animal feed’s taste, promoting a nutritionally balanced diet.
  5. Using salt bricks effectively prevents salt deficiencies in animals, which may otherwise result in various health problems such as muscle cramps, decreased milk yield in cows, and inadequate fatness in meat-producing animals.

Salt Blocks’ Types

  • Different animal types and their specific nutritional needs require various salt licks. Plain salt bricks, which contain mainly sodium chloride, are appropriate for the livestock, fulfilling their necessary salt requirements.
  • Mineral salt blocks contain sodium chloride and essential minerals such as calcium, phosphorus, and magnesium. These salt blocks are particularly advantageous for animals that lack specific minerals.
  • Iodized salt bricks contain iodine, a vital trace element for proper thyroid function. These blocks are indispensable for animals residing in regions with soils deficient in iodine.
  • Selenium is a vital trace mineral for animal well-being. In areas where the soil is deficient in this nutrient, selenium salt bricks can be beneficial in preventing selenium deficiencies.

Salt Bricks’ Benefits in the Nutrition of Animals

There are various advantages of using salt bricks in animals’ nutrition:

  1. Better Hydration: By promoting increased water consumption, salt bricks aid in maintaining the animals’ overall well-being and facilitating proper digestion.
  2. Balanced Nutrition: Salt bricks improve the palatability of feed, guaranteeing that animals consume some nutritionally balanced diet and obtain necessary nutrients.
  3. Health Maintenance: To maintain good health, we recommend salt bricks as they can prevent salt imbalances that can lead to muscle cramps, deficiencies, and other related health problems.
  4. Behavioral Stimulation: Salt brick licking can be a source of behavioral stimulation, providing environmental enrichment and reducing boredom and stress for animals in confinement.
  5. Customization: Farmers can customize their animal’s mineral intake by selecting from various kinds of salt licks, which can address specific needs and deficiencies in the region.

Positioning and Usage

Proper usage and placement are crucial for maximizing the salt blocks' advantages:

  1. Positioning: Put the salt blocks in areas that are easily reachable to animals, like pastures, feeders, or barns
  2. Supervision: Keep an eye on salt intake to ensure that animals are receiving the correct amount. Overconsumption will be detrimental, so it is essential to provide blocks in moderation.
  3. Maintenance: Maintenance is critical to ensure that salt blocks remain clean and uncontaminated, as the presence of debris and dirt may discourage animals from utilizing them.

Licking salt is a way for animals to get essential minerals from salt and other mineral deposits. Mineral licks can be natural or artificial.

Licking salt blocks are artificial mineral licks that farmers place in pastures for livestock or wildlife to lick. They provide essential minerals such as sodium, calcium, iron, zinc, and others.


Licking salt blocks can prevent animals from having abnormal cravings, increase milk production, improve digestion, and enhance performance.


Although often overlooked, salt blocks are crucial to maintaining livestock's health. They offer numerous benefits, including electrolyte balance and appetite stimulation. Farmers and animal owners should know the importance of providing the salt bricks’ appropriate type and ensuring correct usage, and this will guarantee that our animals obtain the necessary nutrients for optimal health and flourishing.
