Mefisto Shock - Farm Case Study

Posted 21st February 2018


Stubbs End Farm, an Egg producer based at Rimmington in Lancashire has previously suffered from Red Mite and according to the Farm Manager, Steve, it has “reduced the egg production and indeed profitability on the farm through the Red Mite irritating the Hens and causing them unnecessary stress”.

Having worked with Biolink for over 5 years Steve contacted Howard Kirby, Biolink Technical Biosecurity Advisor who recommended he try a new product on the market, Mefisto Shock. It has the dual power of an insecticide and disinfectant and could possibly compliment the current Platinum programme Steve was using. Howard recalls “I introduced Mefisto Shock to Steve as it contains Deltamethrin, a strong insecticide used to fight Red Mite. I knew Steve’s Hens were suffering with Red Mite and he needed a cost-effective solution as his egg numbers were reducing. He needed something to help his crop maintain good health.”

Mefisto Shock is an ultra-concentrated formulation that is biodegradable and carcinogen free. It works on all surfaces having a wide spectrum of activity and a long-lasting effect. The powerful insecticide works hard to control the parasites that can cause significant financial losses.

In terms of results Steve said “they are above the breeders’ standard. The Hens came in at 16 weeks and we are at 47 weeks with no sign of Red Mite. Mefisto Shock is the best product we have used from Biolink and I would highly recommend it. When asked about the egg yield Steve was delighted to say “in the last crop we had 319 eggs per bird. The expected yield is 312. With this current crop I am expecting to see an increase on the 319.”
