content by trapping water, further encouraging the growth of microbial populations. Given the scale and complexity of poultry production facilities, any problems related to poor lit- ter quality will be time consuming to resolve and highly likely to lead to economic losses. Determining a good litter management strategy is the key to improvement.
Multi-layer protection The goal for producers is to control and improve the three pa- rameters that are known to affect overall litter quality. Im- provements can be made by reducing litter moisture to limit the growth of pathogenic bacteria, by reducing the pH to around 7 to reduce ammonia volatility, and by controlling the growth of target micro-organisms and by doing so, protect bird health and performance. The ideal litter treatment needs to fit easily into existing oper- ational practices and provide combined protection against all
three risk factors. One approach that offers significant poten- tial in this regard is the use of biological feed additives. Add- ed directly to the feed, this method offers advantages in terms of efficiency for busy production managers and pro- vides long-lasting protection due to the ‘virtuous circle’ it cre- ates; where beneficial bacteria are constantly excreted by the bird into the litter and then eaten again. This mode of action has a distinct advantage compared to alternative products, such as topical chemical amendments, which are known to become ineffective over a relatively short period of time. Of course, any nutritional intervention needs to be supported by robust and credible data to demonstrate its ability to de- liver consistent results on every level. This is particularly im- portant given that many poultry producers are already invest- ing in promoting good gut health and reducing their antibiotic footprint, and so cannot afford for these efforts to be undermined by a poor quality in-house environment. The good news for producers is that there is a viable solution. En- viva Provalen Plus is a multi-strain biological feed additive that uses the latest probiotic (DFM) technology to keep bad bacteria at bay and – unlike many of its competitors – is sup- ported by robust data demonstrating its positive impact on litter quality in countless commercial settings.
