Everything in balance – thanks to dry excretions

Humic acids in poultry feed
Legislation and good practice dictate that poultry should be given access to dry and loose litter at all times. This litter must be suitable for pecking, scratching and dust bathing. Various factors, such as poultry management approaches and the type of feed used, can influence the condition of the litter. Suitable measures must be taken to continuously counteract the presence of encrusted and damp litter. Damp and encrusted litter often causes problems with foot pad health, which is used as a meaningful indicator for assessing animal husbandry.
Feed and damp litter

The main causes of wet litter tend to be greasy and overly liquid excretions from the animals. This in turn can be caused by, for example, a dysbiosis of the intestinal flora, inadequate feed hygiene (toxins) and an unbalanced composition of the amount of feed given (high proportion of non-starch polysaccharides or excessive protein). This means that intestinal stability can have a major impact on litter quality. If the intestine is stable, it can be assumed that the excretions of the animals will be equally stable.

How humic acids from the WH67® brand can help here

WH67® humic acids form a fine protective film over the intestinal mucosa. Electron micrographs confirm that these humic acids are localised in the intervillous spaces, in the goblet cell lumina and in cell walls. In a feeding trial, it was noticed that mucus production in the intestine was increased, which indicates a better-developed epithelium. This results in reduced permeability of the epithelium for toxins and pathogens, or in the reduced ability of these to adhere to the intestinal wall. Humic acids also help bring heightened fluid leakage in the intestine down to a physiological level, thereby promoting physiological muscle tone in the intestine.

Feed conversion and foot pads

Our own trials show that the increased resorption from the feed improves feed conversion rates. The litter stayed drier and had to be topped up less frequently. This was also reflected by the reduced amount of dung. In addition, better screening results were achieved in the foot pad assessments at the slaughterhouse.


  • The quality of litter is very important in poultry farming
  • Feed has a significant impact on litter quality
  • WH67® humic acids are an ideal building block for stabilizing digestion
  • Stable digestion promotes stable excretions and more stable litter quality
