MACRO MINERALS IN LIVESTOCK PRODUCTION SYSTEMS

Updated: Aug 13, 2020

The role of mineral supplementation is extensively documented and often challenged in many circles, so why use minerals and what are you likely to see from using minerals.

Minerals…. the Silver Bullet?

Nothing is further from the truth when we consider livestock production systems, however the objective is to ensure the correct balance of Macro and Micro Minerals are available at critical times to:

Balance the immune system.
Support structural soundness
Support the efficient conversion of protein energy and fibre

Thus providing a healthy animal to underpin a profitable Livestock Enterprise.

Requirements depend on age, growth rates, stage of pregnancy, immune challenges, heat stress and other such physical and environmental challenges.

When searching for answers to what may seem probing questions around mineral supplementation, it is vital that the Total Dietary Intake is taken into consideration.

How it is being offered from home grown paddock feed where massive variations occur to a full TMR (Total Mixed Ration) where we have significant control over inputs. Our TRAC Experts are equip to assist in this area.

Macro Minerals are required in larger quantities than Micro Minerals and generally expressed as g/Kg DMI:

Calcium - required for bone and teeth formation, absorption of Phosphorous and Vitamin D, muscle contraction, enzyme activation, hormonal control. Deficiency signs can be reduced appetite, growth stunting, milk fever/low milk at lambing

Phosphorus - required in almost all metabolic functions, skeletal growth, energy production. Deficiency signs can be weakness, loss of appetite, poor feed conversion, poor fertility, poor lambing rates, chewing wood, rocks, bone

Magnesium - the only mineral absorbed in the rumen. Required for Ca, P and Vitamin D absorption, and glucose production and many enzyme reactions. High Potassium affects Mg absorption; Cannot be stored and needs to be supplied every day.

Deficiency signs can be reduced intake and performance, rapid breath, stiff gait, grass tetany, low milk production

Sodium – Regulates the osmolarity of body fluids, Ph, assists with muscle and nervous function and helps to excrete excess K.
