Ropadiar, a feed supplement for pigs and poultry marketed by Quality Equipment-G.E. Baker is based on the natural herb oregano and acts as an appetiser and flavouring agent. It increases feed intake, and therefore growth rate, particularly among weaners and growing pigs as well as broilers. Improved performance has also been recorded in egg layers. Suitable for both feed manufacturers and home-mixers, it is available in 25 kg bags and 7.5 kg tubs. Ropadiar is added to diets at between 150g and 500g per tonne. Being a natural product, no withdrawal time is necessary.
