Please reword the following paragraph
In case these are deemed not to be sufficient, additional indicators such as price difference between medicated feed and compound feed or share of VMPs sold as premixes could be sourced from representatives of the industry.
If it did not appear adequate additional indicators could have been obtained from the representatives of the sector, e.g. price differences between medicated feedstuffs and mixture feedstuffs, or percentage of veterinary medicines marketed as premixtures.
