Virbac, the French group of companies, increased its sales only slightly in the first half of 2003 compared with the same period last year. The volume of 183.9 mio euro is equivalent to an increase of 0.1 per cent. It was only the second-quarter business trend in the pet and working animal segment that enabled the supplier of feed and animal pharmaceutical products to record any increase at all. Interest rates were to blame for the poor sales performance, according to the company.
