Efficient shed disinfection

Hygiene management in livestock farming

In modern livestock farming, regular, thorough cleaning and subsequent professional disinfection of shed enclosures is a fundamental requirement to ensure animal health.

A lack of hygiene management will lead to an increase in germ diversity and to a surge in the total germ load. It can produce unnecessary strain on animal immune systems and increase performance-reducing illnesses. General germ reduction and a break in an infection chain reduce the risk of disease. Thorough cleaning followed by disinfection of shed facilities prevent certain pathogens from multiplying.

Cleaning livestock sheds

Efficient stable disinfection strongly depends on prior effective cleaning. Fat and protein films are carriers of infective agents. and cannot be easily removed with a pressure washer. Disinfectants applied after a pressure wash cannot penetrate them.

That's why facilities should be cleaned thoroughly before disinfection, usually with a chemical cleaning agent. The Desintec hygiene range offers high-alkaline cleaning concentrate with high degreasing and dirt-removing power with the products StallClean Basis and StallClean Profi. Their use particularly improves cleaning with shorter cleaning times where fat-containing faeces is involved and helps to reduce water consumption.

Work steps when using StallClean Basis and StallClean Profi:

• Move animals out of the shed
• Make preparations, such as removing movable equipment and sweeping out the shed completely
• Use a soaking system to soak the shed
• Foam the shed with a 1–2 per cent StallClean Basis and StallClean Profi application solution shortly before pressure washing
• Clean shed thoroughly with pressure washer

Shed disinfection

Where there is a subsequent disinfection it should be considered that the various germ compositions require a targeted implementation of disinfectant. General disinfectants with an aldehyde and acidic base will combat fundamental germ groups such as bacteria and viruses.

You must comply with the disinfection measures as follows:

• Disinfect the wet shed with Alzogur to combat dysentery and flies. The amount of Alzogur you apply is calculated based on the quantity of remaining manure and is then applied uniformly across the wet slatted flow using a watering can with a large-holed rose. Rinse off the shed surfaces thoroughly after an exposure time of one to two hours until the blue shimmer has disappeared.
• Let the shed surfaces dry completely. They must no longer be damp.
• Apply general disinfectant to eliminate bacteria and viruses with peracetic acid-based Desintec Peroxx liquid or alternatively, with glutaraldehyde-based Desintec FL-des GA forte. Both are DVG-approved.
• If you also require an antiparasitic disinfection to eliminate worm eggs in addition to anti-microbial disinfection, we recommend Desintec FL-des Allround.
• This two-component preparation is DVG-listed and is effective in eliminating bacteria, viruses, fungi and parasites such as coccidia and worm eggs in a single work step.
• Allow for an exposure time of two hours, then ensure shed surfaces dry completely.

Both potency and cost per square metre are important factors when choosing your standard disinfectant. The DVG-listed Desintec product Peroxx Liquid only requires a 0.5 per cent solution to ensure an optimal disinfection result to eliminate bacteria and viruses (enveloped and non-enveloped). The corrosion-reducing, fast-acting product composition is particularly effective against bacteria and viruses, as proven in microbiological tests for livestock farming. Peroxx Liquid is also effective at lower temperatures (10 °C).

Calculating application solution for disinfectant:

Shed surface in square metres x 0.4 litres of application solution (as per DVG) x 1.7 (factor for walls, partition grids and shed equipment) = application solution in litres.

Surface disinfection with Peroxx Liquid

The Desintec Peroxx liquid solution is applied with the usual application devices for peracetic acid (e.g. 200-litre disinfection trolley or stainless steel disinfection lances) onto the dried service after cleaning. The costs per 100 square metres of shed surface are only around 2–3 euros with corresponding savings.

Necessary application concentration (%) and exposure time (min.) for Desintec Peroxx Liquid as specified in the DVG listing:

Bactericide:

• Special disinfection: 0.75%/30 min. or 0.5%/60–120 min.
• (At 10 °C); preventative disinfection: 0.5%/30–60 min. or 0.25%/120 min.

Virucide:

• Non-enveloped viruses: 0.75%/30 min. or 0.5%/60 min. or 0.25%/120 min.
• (At 20 °C); enveloped viruses: 0.5%/30 min. or 0.25%/60–120 min.

Use biocides carefully. Always read the label and product information before use.
