Broiler litter: 1 year old or … Poultry Litter Management Keeping litter dry is a critical part of overall management on every poultry farm. Adding Fresh Litter. There are three types of alum can be used in poultry houses; dry, liquid and high acid liquid alum (this paper focuses on dry alum). pH Shield treated litter has less caking for easier house preparation and is lower in pH at the end of the flock, which provides better ammonia control at the start of the next flock. In cold weather this may necessitate increasing the heating levels within the house. Aluminum sulfate (alum) additions to poultry litter have been shown to reduce ammonia concentrations in and emissions from poultry rearing facilities. Miles, D. M., S. L. Branton, and B. D. Lott, 2004. Drinker management, which decreases total water spillage, will reduce the total amount of moisture in the barn and lower ammonia production in the litter. Automatic manoeveuring of air flow through automated ventilation when the desired moisture level is exceeded, will help. Moisture management is the key to good poultry litter management. There are several strategies for decreasing ammonia in the barn. Dry litter helps control ammonia levels, provides a healthy flock environment, and reduces condemnations due to hock and footpad burns and breast blisters. Poultry litter moisture management to reduce ammonia. Litter amendments are used to mitigate ammonia problems. Adding alum to litter also decreases phosphorus runoff. Adding fresh litter has an immediate effect on ammonia production because it forms a dry, physical barrier which prevents ammonia release into the air. Get this from a library! Moisture management ... Ventilate ammonia to protect workers Lower curtains when personnel in house decaking or other work. POULTRY MANAGEMENT Maintain a healthy flock. This study examined the effect of incorporating biochar during composting of poultry litter on ammonia (NH 3) volatilisation and N retention. Generally speaking, the ideal relative humidity would be approximately 50%. The ability of a litter material to absorb and release moisture is the key property in maintaining an optimum pen environment. Problems occurring due to high-performance genetics, feed formulation and medication can lead to production of wet manure, causing increased ammonia and odor release alongside reduced broiler performance and feed … However, this should only be in accordance with the climate and temperature of the poultry house. As the relative humidity of the air in the house climbs, so does litter moisture. Litter is a very important commodity in poultry growing, as birds are exposed from the first day of life to the litter and its contents (microbes, moisture, ammonia, dust, odour, and texture). Over time, higher ventilation rates will tend to reduce litter moisture levels, which in turn will reduce the ammonia generation rate, which in turn leads to lower ammonia levels. Probably the most important of these factors in litter management is moisture control. Excessive ammonia production following addition of water to litter to bring moisture content up to 28-34% has also been observed in Australia. The ammonia released at 75°F with 25% litter moisture is 1 .4 times more than at the same temperature with 20% litter moisture. Further rise in litter moisture to 30% releases 1 .8 times the ammonia.
