1.. The additive shall be incorporated into feed in the form of a premixture.
2.. For user safety: breathing protection, safety glasses and gloves should be worn during handling.
3.. The following words shall be included in the labelling:

— For feed for sheep if the level of copper in the feed exceeds 10 mg/kg:
'The level of copper in this feed may cause poisoning in certain breeds of sheep.'
— For feed for bovines after the start of rumination if the level of copper in the feed is less than 20 mg/kg:
'The level of copper in this feed may cause copper deficiencies in cattle grazing pastures with high contents of molybdenum or sulphur.' 16 April 2022
