Understanding Acids and Their Potential in Poultry LItter

Treating litter with an acidifier is a fairly common practice in poultry production, used as a way to control ammonia and maintain a favorable environment for bird welfare. While the benefits of acidification are often discussed, most people don’t often think about what qualifies a chemical as an acid, the different types of acids, and how they work.

The Bioavailability of Nitrogen in Poultry Litter Following PLT Application

Poultry litter is recognized as an excellent source of plant nutrients (nitrogen, phosphorus and potassium) and organic matter. Nitrogen (N) is excreted from birds in the form of uric acid in the manure. Inorganic forms of N such as ammonium nitrate (NH4-N) and nitrate nitrogen (NO3-N) account for roughly 14% of the total litter N. The remaining 86% of the total litter N is in the form of organic N. This paper details research that supports the fact that PLT® use increases litter N content by reducing ammonia volatilization, increasing ammonium nitrogen and forming ammonium sulfate.

The Case for Air Quality Surveys: Reduce Respiratory Disease Risk, Improve Performance

Air quality surveys are a valuable tool that allow integrators to look at trends of air quality in broiler houses, serving as an effective indicator to gauge if litter amendments are being utilized effectively. They also provide a wealth of actionable data that can be used to reduce the impact of ammonia on respiratory health.

Accurately Measuring Ammonia Levels in Poultry Houses

There are a number of tools available to producers that can help determine ammonia levels in poultry houses. While some cost hundreds of dollars and require frequent calibration, there are a number of low cost, easy to use and relatively accurate options that can be used to determine whether ammonia has reached harmful levels.

House Preparation and Brooding in the Face of Fuel Shortages

In the face of fuel shortages and high fuel costs, growers often make decisions regarding house preparation and brooding that they would not have made under rosier circumstances. In such events, these decisions can either minimize impact or cause harmful consequences from which the flock tends not to recover.

Litter Management for Improved Health and Welfare

Litter management is an evolving process. Just when we think we’re getting it right, things change. Changes in production, such as different bird sizes, densities and the introduction of more ABF and organic programs, demand a constant review of a litter management program. Without it, producers can easily step back on their litter management effectiveness, which can impact paw quality and overall bird health and welfare.

Prevention and Scoring of Paw Lesions

Fifteen years ago, who would have thought that chicken paws would have become such an important part of the U.S. poultry industry? Today, good paws are integral to a complex’s profitability and are quite often the most profitable part of the chicken. The presence of paw or footpad lesions (pododermatitis or footpad dermatitis) is the number one cause of downgrades of chicken feet. Since there is no market for Grade “B” paws, the presence of footpad lesions can seriously erode a complex’s bottom line.

PLT Increases Fertilizer Value of Poultry Litter

Based on current inorganic nitrogen costs, broiler litter is currently valued at $105 per ton based on its nitrogen content alone. When its value as a soil amendment with trace minerals and organic matter is considered, the value of poultry litter rises farther above the nitrogen content alone.
