A recent layer discussion evening hosted by Sandhill Vets focussed on the growing importance of strong biosecurity and targeted disease prevention to maintain flock health and production.
Speakers stressed that thorough cleaning with detergent remains the foundation of good biosecurity, as disinfectants are far less effective in the presence of organic matter. Choosing the right disinfectant depends on temperature, pathogen risk and required contact time.
Investigating egg drops requires accurate, up-to-date records, said Sandhill Vets’ Laura Langstaff. Infectious Bronchitis (IB) continues to be a common finding and acts as a gateway for other diseases, making regular vaccination in lay essential.
Worm burdens are rising, according to vet Dan King, with more cases of Capillaria and tapeworms and increasing problems in housed birds. He recommended routine worm egg counts, site-specific worming plans and good litter management.
Red mite remains a major welfare and economic issue, with even low burdens causing significant losses. MSD Animal Health’s Lee Housel encouraged integrated control strategies and thorough cleaning at turnaround.
Water quality was highlighted by Agrihealth’s Stephen Neale, who warned that biofilm in water lines can reduce vaccine efficacy and harbour harmful bacteria. Regular sanitising, especially at turnaround, was strongly advised.
The meeting concluded that farms combining strong biosecurity, IB control, worm monitoring and clean water consistently achieve higher, more stable production, with some flocks finishing lay above 90%.
