| 3c371ii | - | L-valine | Additive compositionPowder with a minimum content of L-valine of 98 % (on a dry matter basis) and a maximum content of 1,5 % water. | All species | - | 1. The additive may be used via water for drinking.2. In the directions for use of the additive and premixture, the storage conditions, the stability to heat treatment and the stability in water for drinking shall be indicated.3. The label of the additive and premixture shall indicate the following: The supplementation with L-valine, in particular via water for drinking, should take into account all essential and conditional essential amino acids in order to avoid imbalances.4. For users of the additive and premixtures, feed business operators shall establish operational procedures and organisational measures to address the potential risks by inhalation, eye or dermal contact. Where those risks cannot be eliminated or reduced to a minimum by such procedures and measures, the additive and premixtures shall be used with appropriate personal protective equipment, including eyes, skin and breathing protection. | 19 December 2031 | ||
