33 benefits of trace minerals for cattle and why you should supplement them

Trace minerals for cattle


3 minute read


Supplementation of the necessary trace minerals improves the overall well-being of cattle: supplemented cattle develop a higher resistance against diseases, reach optimal growth, and have an increased reproduction. These minerals can be supplemented in numerous ways such as lick blocks and ruminal boluses. But what exactly do all these minerals contribute to cattle? To give you an idea of the necessity of trace minerals for cattle we summarized the benefits of copper, cobalt, selenium, zinc, and iodine.

Why should a farmer supplement trace minerals to cattle?

A deficiency in trace minerals is linked to numerous fertility problems, inflammatory diseases, insufficient growth, and other complications affecting the profitability of cattle. We dived into an endless amount of scientific papers and books (drinking liters of amazing Colombian coffee) so you don’ have to and summarized 33 ways in which cattle benefit from the supplementation of trace elements, proving that supplementation is definitely worth the investment.

Trace minerals for cattle



  • Less reproductive problems such as early embryonic death and retained placenta
  • Higher fertility because of less delayed or depressed estrus
  • Improved conception rates
  • Higher quality semen production


  • Growth of tendons and ligaments
  • Involved in energy production


  • Decreased cholesterol with possible health benefits on humans
  • Involved in red cell production




  • Increased fertility
  • Improved conception rate
  • General better conditioning of the calve


  • Better rumen fermentation by increased fiber digestion of low-quality forages
  • Prevents developmental and growth problems
  • Fewer delays of puberty


  • Cobalt plays a role in the development of vitamin B12 which is vital for energy metabolism and the production of red blood cells




  • Improved conception rate
  • Reduces the cases of retained placenta
  • Fewer calf death losses
  • Overall stronger calves at birth


  • Increased calf weight


  • Fewer cases of mastitis and metritis
  • Helps with the production of antibodies



  • An increase in daily gain for fattening beef cattle.
  • Bone and cartilage development


  • A decreased susceptibility to infection
  • Antioxidant actions (cell protection)




  • Less failure of fertilization
  • Higher conception rate


  • Improvement of growth
  • Improvement of brain development
  • Less delay of puberty
  • Influences the development of the fetus (Puls, 1994) and the conception rate (Yasothai, 2014).

Mineral boluses for Cattle


A bolus is a complementary feed that is becoming more and more popular since it’s an easy and economical solution to enrich an animal's diet. With only one bolus the vitamin and mineral requirements of the herd are covered for a few hours up to six months. Resco developed two different mineral boluses with a slow-release effect ensuring that your cattle’s requirements are met during six months.

High Trace


Our trace mineral bolus High Trace is a slow-release cattle supplement designed to prevent a trace mineral deficiency in cattle and improve the overall wellbeing of the cows. High Trace can be used for cows over 250 kg.

Minerals for cattle with a High Trace bolus



Tracetop is a mineral bolus containing all the benefits of the High Trace bolus, but with vitamins added to the formula.
