Optimizing water quality on poultry, pig and dairy farms

 

In practice, it is common for drinking water quality not to be optimal on farms. Water quality can be affected by temperature fluctuations, damage to pipe work, dead-end pipes, bends, pipe diameter and nipple connections.

It is good practice to have the water pipes checked regularly (i.e. swabbed and microbiologically tested) and to clean them thoroughly. Biofilms – the protective environment on surfaces that bacteria can live in that allows them to survive longer and resist routine cleaning – must be removed or not allowed to build up. Therefore, in addition to a cleaning agent, a disinfectant should be used to tackle the biofilm. At least once a week, perform a visual check of taps and pipework using a white bucket or transparent measuring cup. During cleaning, have the water supply checked by a specialist using an endoscope. In this way, a deterioration of the water quality can be observed over time. Check which products are effective against biofilms.

The water quality should be so good that you dare to drink it yourself! Good quality water saves you money by avoiding persistent infections that can lower an animal’s immune system and lead to unnecessary or excessive antibiotic use. Clean water = less need for antibiotics.

Pest prevention on poultry, pig and dairy farms

 

Pests, such as rodents, insects and birds can enter sheds/stables/housing and multiply, which then increases the risk of disease entering and spreading on farm.

Flies can be controlled both biologically and chemically. Predator flies or parasitic wasps (the fly’s natural enemy) can be released into the stable/shed 5 to 6 times a year. Manure can also be treated several times a year with a pesticide that kills the maggots of the flies. Some products can be distributed over the manure pit surface. It is best practice to keep pests out of the farm premises as much as possible. For example, by completely blocking the entrance to livestock housing with the nets or using decoy boxes to control rats and mice.

Proper pest control reduces damage caused by pests as well as limiting the spread of diseases that e.g. flies, birds or rodents carry and spread. This leads to improved livestock health, farm hygiene and job satisfaction. Companies as for example MS Schippers and Agro Pest Control can offer pest control products.

 

The right working method: Standard Operating Procedures (SOPs)

 

Using Standard Operating Procedures (SOPs) on farm is an important tool to prevent pathogens (bacteria, viruses) from moving around the farm and infecting other animals. They allow you to review processes for improvement and ensure all staff are following the same protocol to the same standard. A good working method goes beyond the use of a hygiene lock and the supply and removal of animals. It is about the daily routines. For each animal category or age group, try to use separate clothing and materials, indicated by different colours so there is no cross over. Clean and disinfect hands and boots each time you leave an area or stock group. Additionally, apply working systems so that farm workers do not spread disease between age groups or management groups. For example, build pens so that employees can work from young animals up to older animals without having to walk through other areas or pens.

Changing your daily routine is a big step towards minimizing the spread of disease. With a colour coding system for equipment and structuring pens, housing and facilities adequately, you can strive for the highest possible health status and reduce disease transmission.

Instructive training on biosecurity and application of Biocheck: a risk-based scoring tool for biosecurity on livestock farms

On 22 and 23 of January 2020, the Faculty of Veterinary Medicine of Ghent University hosted a very instructive and interesting training on biosecurity and the use of their Biocheck, a tool to score and benchmark the biosecurity measures on livestock farms. The training nicely balanced theoretical insights with hands-on practical training and field visits to a farrowing and broiler farm to exercise the use of the Biocheck.

Five principles to biosecurity

Prof. Jeroen Dewulf, head of the chair on epidemiology started the training with a lecture on the five main principles of biosecurity and practical examples to illustrate and respect these principles in order to prevent disease from entering the farm and spread within it. The principles being:

  1. Preventing direct and indirect contact between potentially infectious and susceptible animals
  2. Not every route of transmission is equally important, so not every biosecurity measure is equally effective
  3. Lower the general infection pressure on the farm to lower the burden on the immune system of the animals
  4. Size matters meaning that although biosecurity is important on every farm, on larger farms the risk and negative consequences of disease outbreaks will be much larger and harder to contain than on smaller farms.
  5. Frequency matters: the frequency of events or actions happening on the farm determine the risks. An event or action (e.g. feed truck delivering feed) with a low probability of infecting the farm per visit can pose a substantial risk for the farm when it reoccurs frequently.

Next, prof. Dewulf explained these principles and suitable external and internal biosecurity measures in more detail with practical examples for pig production.

Scoring and benchmarking biosecurity with Biocheck

The final theoretical part of the first day was focused on the UGhent’s Biocheck. This innovative risk-based scoring system can elevate the European livestock sectors’ biosecurity status since it is the first system to quantitatively score and benchmark the biosecurity of farms in pig, poultry, dairy, beef and veal production. The checklist evaluates the farm’s biosecurity measures and takes into account the relative risks of different infection transmission routes resulting in an overall biosecurity score out of a 100 for the farm as well as detailed scores for external and internal biosecurity separately. The highest detail of scoring offers farmers and vets immediate insight into measures to improve within both the domains of external and internal biosecurity.

In the afternoon, the theory on biosecurity in general and the use of the Biocheck was nicely illustrated with a visit to a farrowing farm of a thousand sows and being a text book example of managing biosecurity in pig production. Here participants got the chance to exercise in evaluating a farms’ biosecurity status by use of the Biocheck.

Day 2: Focus on poultry production

The second day of training was focused on biosecurity in poultry and especially broiler production. D r Nele Caekebeke focused first on specific biosecurity aspects in poultry production, after which the participants had to exercise in designing and improving biosecurity measures on specific broiler farms.

The poultry training was finalized with another field visit to an integrated broiler farm where the participants could practice the Biocheck scoring in broiler production.
