Step Towards “Ammonia- Free” Environment For Poultry

Step Towards “Ammonia- Free” Environment For PoultryNitrogen is highly found in animal excreta and can exist in various forms. One such form is “Ammonia”. Primarily ammonia is a result of breakdown of urea present in urine of birds by the enzymes; urease and uricase. It is a potential source to create bad odour and negatively impact air and water quality and animal as well as human health. Presence of ammonia above 25ppm in the poultry house can damage the respiratory system of the birds and also there is a reduction in immune system; leading to declining flock health and performance. In addition to the effects on bird’s health, ammonia has significant hazardous effect on the caretakers and to the environmental ecology.

High levels of ammonia emission inside the poultry house have also become a cause of concern for the atmosphere outside the poultry house. Therefore there is a great need to develop strategies to reduce ammonia formation, volatilization, or downwind transmission of ammonia after it is volatilised from the poultry manure to minimise the harmful effects of ammonia on animal and human health as well as the environment.

Keeping this in mind and with a view to develop ‘ammonia- free ‘and organic environment for all, Vinayak Ingredients have launched a product with a brand name “KiFAY” which is a blend of various herbal extracts in a diatomaceous carrier which acts as a DL-Methionine replacer and a nutritional feed additive and goes directly into the feed and acts as an amino acid optimiser and improves the apparent ileal digestibility of the feed and hence improves the protein turnover this also reduces the amount of amino acid degradation by the liver and excretion by kidney which form the major part of nitrogen compounds excreted by poultry. In turn these compounds are also responsible for ammonia and smell in the poultry house, apart from posing stressors for liver and kidney.

Vinayak Ingredients have also launched a Bio-security product which combats the remaining ammonia emission in the droppings of the birds which acts as a litter amendment system under the brand name of “ESSENTIOLITT-POULTRY”. Essentiolitt poultry is an ammonia binder and has bactericidal action on urease and uricase enzymes and inhibit the ammonia formation by increasing 45% nitrogen retention and ammonia emission.

How can litter amendment systems be of help to the environment?

How can litter amendment systems be of help to the environmentLitter amendment refers to the treatment of the poultry litter with chemical, herbal or biological remedies to reduce ammonia emissions, microbial contamination and insect infestations on farms. The poultry litter is an excellent source of nitrogen rich nutrition for plants, thus many farmers sell the same as manure for significant revenue. The treatment of such manure is necessary owing to the high level of bacterial and fungal contamination’s coming from the poultry gut.

As amino acids and undigested nutrients form a big chunk of excreta of broilers or layers, this medium is enriched further for aerobic and anaerobic growth. The urea and uric acid deposited on the litter is converted into ammonia by a number of bacteria and fungi. This conversion is not only deleterious for the environment as pollutants, but also is harmful for the birds as the gas predisposes them to a respiratory etiology. As the nitrogen depletes from the litter and leaches into the environment it reduces the quality of poultry litter to be used as manure. Use of litter amendment systems with antimicrobial properties which is also safe for application with the birds present on the litter is essential.

These natural or chemical substances should be also targeting the urease and uricase positive bacteria and thus also reduce nitrogen depletion from litter as well as concurrently also affecting the ammonia formation in the poultry house. In the advent of complete environmentally controlled houses another important reason to use litter amendment systems is to reduce the litter moisture and thus also help control the humidity in the house. The dessicatory effects of such products also help in cooling the house more efficiently and curb ammonia emissions from the litter. As more concentration of good air exchange occurs between the house and the environment, the effect of ammonia on the environment can be curbed. A complete litter amendment system should possess all these qualities combined with the ease of application and preferably being a solution of natural origin for easy bio-degradation.
