Although most of the attention on drystock farms is turned firmly towards activity out in the fields, mid-summer can often provide an opportunity to put in some preparations indoors for the coming winter.

Washing and disinfecting should be the first thing to spring to mind here.

Obviously, it’s pleasing to see the yard and sheds cleaned once a year, but washing and disinfecting are not done just for aesthetic purposes.

The primary function is to control bacteria, viruses, fungi and mites that live in place like faecal material, bedding, feed residue and cobwebs, for example.

Research conclusively shows that a proper hygiene routine during the summer will pay dividends in reducing the disease burden in livestock areas the following winter.

All areas associated with livestock should be focused on.

This includes slatted houses, straw-bedded sheds, calving pens, handling units and even feed stores.

Washing and disinfecting early in the summer and allowing sheds to dry for a long period of time will be even more beneficial.

Desiccation (a state of extreme dryness) will actually act as further disinfection.

Washing

Before washing, all excess material like dung and feed residue should be cleaned from the sheds first.

Power-washing is then the best option to thoroughly clean all areas.

Slatted houses are often the most difficult.

Start by scraping excess faecal matter and feed from the top of and in between the slats.

After this, overnight soaking with water will loosen most of the material before a thorough washing the next day.

Always pay particular attention to steel work to prevent corroding, which will increase the life-span of the structure and penning.

Roofs should be washed on the inside to remove dust and cob-webs and also to clean lights and clear sheeting.

Remember, the electricity supply should also be cut-off in the shed where washing is taking place.

Finally, while washing pay close attention to drinker troughs and feed passages/troughs.

Disinfecting

Disinfectants differ in the dilution rate, types of pathogens they kill and the contact time required (typically a few hours).

Most disinfectants are liquids, but powder disinfectants are also available.

Also, some disinfectants need to be applied to a dry surface, while others work better by soaking all surfaces thoroughly before application and allowing the disinfectant to dry in after.

Because of these variances, it is best to discuss disinfectant choice with your local vet or agricultural adviser.

Disinfectants approved for use against TB and other notifiable diseases are also listed on the Department of Agriculture list.

Liquid disinfectants can be applied through a low-pressure power washer or knapsack sprayer.

Mixing the disinfectant with water and fairy liquid will generate a foamy mixture.

Finally, disinfectants can irritate skin and eyes and can also stain and corrode.

It is important that all personnel wear washable clothing and use personal protective equipment (PPE) like a mask, goggles, gloves and a gown when handling, mixing and applying disinfectants.
