When and how to provide minerals?

Solution name: When and how to provide minerals?

Aim: To cover the animals’ needs in minerals and vitamins whilst avoiding excesses. To provide a mineral supplementation plan for grazing ewes

Description:

When ewes are grazing, mineral and vitamin treatments at specific times are sufficient, i.e., one month before mating and at least one month before lambing. During the other physiological stages, it is recommended to apply a one-month treatment followed by one or two months without supplementation. However, salt must be accessible all year round.

 How to implement it:

Different alternatives for intake, including their benefits and limitations, include:

  • Vitaminised mineral feed (pellets or semolina) is the cheapest and most effective alternative for the animal.
  • Pump feeds are effective but more expensive.
  • Overconsumption of mineral licks, related to levels in molasses, is very expensive and can lead to health problems.
  • Boluses are effective in case of a specific deficiency but are also more expensive, and do not replace important trace elements (although they are effective over a longer period).
  • Drinkable and injectable shock doses (single intake) are poor value for money.
  • Addition of an element to grasslands through enriched fertilisers (e.g., selenium) is less effective than direct assimilation by the animal.
  • If there is no particular health problem in the herd, organic or chelated forms do not suffice (unless there is too much of an element which cannot be corrected)
