Factors affecting vitamin stability in animal feed.

Factors affecting vitamin stability in animal feed. 🐄🐂

▪️ Forage species

Grasses have the lowest level of ᵦ-carotene.

while legumes have the highest level.


▪️ Stage of maturity

The levels of ᵦ-carotene and 𝛼-tocopherol in the grasses and legumes are very high in the young stages and reduce as the plant matures.


▪️ Climatic conditions

a forage is richer in ᵦ-carotene and 𝛼-tocopherol is in conditions with a low temperature.


▪️ Haymaking

Drying crops either on the ground or in barns reduces the vitamin levels.


▪️ Ensiling

Stability of some vitamins such as vitamin A may be adversely affected if mouldy or spoiled silages are fed for long periods.


▪️ Composition of the premix

The type of trace mineral can have a significant effect on vitamin stability.


▪️ Pelleting

Pelleting is typically the most aggressive process against vitamins due to exposure to heat.


▪️ Storage

Premixes containing vitamins can be stored for about 3 to 4 months.
