Canthaxanthin-based red dye
Oropharma Can-Tax is a red dye based on canthaxanthin.
This dietary supplement colors red canaries, intensifies the red color in other birds and ensures a beautiful uniform red color.
By adding Can-Tax to the feed, the canthaxanthin is transported to the place where the feather grows and is given the most intense red color.
The formed feather retains its color until the formation of a new feather.
