According to Paul Anderson, a partner in 'Happy Pigs' at Hopton, near Hodnet, giving the already-keen boars the natural supplement, Biotilan gives them an extra boost. "It definitely sharpens them up. I have taken it myself and it has given me extra energy!" he commented.

The supplement - now called Immunall - made in Holland from extracts from seven herbs, is given at the rate of 5 ml per day for four weeks, followed by a week's rest, to help the immune system.

The herd is achieving good results. To overcome health problems, it was completely depopulated and restocked with PRRS- and PMWS-negative Genepacker 120 gilts and 25 Quantum boars from JSR Genetics in April 2003.

Having averaged 10.6 piglets born alive in their first parities, the first few gilts which have come round for their second litters are now averaging 11.5 born alive. The ad lib-fed finishing pigs have an average P2 measurement of 10.6 mm at 76 kg deadweight.
