Escherichia coli (E. coli) is a Gram-negative rod-shaped bacterium. It is the most common bacteria in poultry and is present in the environment and the normal intestinal flora of poultry. The E. coli bacteria is not harmful under normal circumstances.

Cause E. coli with poultry?

The source of infection of E. coli is in the parent stock. They transfer E. coli through the eggs to the hatcheries and from hatcheries it is possibly transferred to the broilers and layers.

In case of other problems, a massive growth of the E. coli bacteria occurs, such as:

  • in the case of secondary infections
  • a weakened immune system
  • a weakened intestinal wall
  • weakened air pockets
  • skin lesions

Characteristics with dams

  • Peritonitis is the most common symptom, this is caused by intestinal penetration and airway penetration
  • Fallopian tube inflammation
  • Airway inflammation

Infestation route E. coli parent stock / laying hens:

  • 1. Cloaca: the orbicular muscle between the vagina and cloaca can relax too much, so that fertilizer particles with E. coli can reach the vagina and fallopian tube
  • 2. Intestinal wall: E. coli can get into the abdominal cavity via the intestinal tract and the intestinal wall
  • 3. Airways: E. coli bacteria can get in the fallopian tubes and abdominal cavity via the air bags

Characteristics with broilers

  • Yolk rest inflammation in the first week of life. The mortality can get as high as 15%
  • Intestinal problems cause reduced digestion and provide poorer technical results
  • Blood infection leads to an increased mortality

Infestation route E. coli broilers:

  • 1. Airways: E. coli bacteria can get in the fallopian tubes and abdominal cavity via the air bags
  • 2. Intestinal wall: E. coli can get into the abdominal cavity via the intestinal tract and the intestinal wall
  • 3. Via the parent stock: in the egg through contaminated fallopian tubes or contaminated shell (cloaca, contaminated manure)

Consequences E. coli with poultry

  • Reduced lay
  • Increased mortality

Prevention of E. coli with poultry

It is of great importance to minimalize the risk factors of E. coli. The hygiene and drinking water quality should be in great condition. There should be an optimal digestion and intestinal health. The stress level must be minimized.

Take care of clean drinking water pipes

A clean drinking water supply and clean water is important for the welfare of the poultry as water is the most important nutrient for poultry. Di-O-Clean ensures clean drinking water pipes by:

  • The removal and prevention of biofilm in the water pipes
  • The removal of iron and manganese deposits in the water pipes
  • Germ-free and healthy drinking water
  • In addition, Di-O-Clean is not corrosive to the drinking water system, there is no build-up of resistance and the smell and taste of the water is not adversely affected

Ensure maximum resistance

A good resistance can reduce the chance on E. coli infections. It is therefore of great importance that the intestines are well developed. Acids ensure optimal intestinal flora and digestion. The most organic acids do not contain essential oils, while these have a very beneficial effect on the control of E. coli. Health contains lactic acid, formic acid and essential oils and has an antibacterial effect:

  • Lactic acid is effective against E. coli and can kill E. coli
  • Formic acid stops the growth of E. coli, and has a proven effect on lowering the pH
  • Essential oils provide maximum effect, even at pH values> 5 (organic acids are effective till a pH <5)
  • Goldfeed® Health ensures an optimal intestinal flora and digestion. E. coli infections have less chance to develop themselves. The preventive dose is 3 days per week per month and the curative dose in case of an E. coli outbreak is 2 weeks.
  • Facet is a condition preparation to optimize the overall resistance, preventative and curative, with dams/laying hens and broilers. The dosage is 4 litres to 1.000 litres of drinking water, preventively 3 days per week per month and curative for 2 weeks.

Provide a low load of bacteria with hatching of hatching eggs

For a low load of bacteria with hatching of hatching eggs MS Oxy-Clean can be used.

  • Broad spectrum: control of bacteria, yeasts and fungi
  • Positive effect on hatchability of fertilized eggs
  • Research shows that there are less colony forming units (cfu) on eggs after treatment with MS Oxy-Clean (0.6 - 1.3) in comparison to Formalin (3 - 3.75)
  • We recommend MS Power Mister to atomize MS Oxy-Clean. The fine spray provides a homogeneous distribution of MS Oxy-Clean over the eggs, with less consumption of the product in comparison with other spraying methods.

Ensure optimum hygiene in the stable by using the following hygiene protocol

Good hygiene before, during and after the laying period in the stable and outside is important to decrease the risk of diseases and secondary infections such as E. coli Before new animals enter the stable, the stable should always be cleaned and disinfected wet. Follow the following protocol.

  • 1. Good preparation: Remove manure and materials that do not belong in the stable.
  • 2. Foaming: Foam the stable and materials with MS Topfoam LC ALK (application concentration of 2% and exposure time up to 2 hours).
  • 3. Cleaning: Spray the stable clean with high pressure and rinse with low pressure.
  • 4. Disinfection: Disinfect with broad-spectrum products to kill all remaining micro-organisms. Rinse with water and allow to dry.
