Poultry litter
Poultry litter is the mix of bedding material, manure and feathers that result from intensive poultry production. This includes litter from meat chickens (broilers), egg-laying chickens (layers) kept under barn conditions, turkeys, ducks and quails. Poultry bedding material consists of wood shavings, pine straw, peanut hulls, and other absorbent dry low-cost materials and is another possible source of pathogenic contamination for poultry. It is generally recommended that farmers keep litter as dry as possible, replace the top layer of the litter with a new one, and apply acid-based litter amendments. Keeping litter dry is a critical part of overall management on every poultry farm. Litter conditions influence bird performance, which in turn affects profits of growers and integrators. Dry litter helps control ammonia levels, provides a healthy flock environment, and reduces condemnations due to hock and footpad burns and breast blisters.
Introduction Many parameters such as temperature and humidity affect environmental conditions within a poultry house. Heat and cold stresses, wet litter and ammonia emissions are among the extreme conditions adversely affecting the poultry performance (Al-Homidan et al., 2003). The two later factors are associated with another factor termed stocking density as a debating issue in intensive poultry production (Dozier et al., 2006; Estevez, 2007). Increasing stocking density is an...

Introduction Agricultural dust is generated in animal production facilities (Cambra-Lopez et al., 2010). Inhalation exposure to agricultural dust induces pulmonary inflammation and can lead to the development of chronic respiratory diseases (Palmberg et al., 1998; Redente and Massengale, 2006; Poole and Romberger, 2012). Several studies have demonstrated that agricultural workers, particularly poultry workers, have a...

Introduction The poultry industry has been able to develop high-level technologies in these more than one hundred years of existence, reaching high zootechnical results. These advances have been obtained through a lot of financial investment in ambience, making the handling work more efficient. However, to offset this economic contribution, the producers were taken to increase the population density in aviary, mainly broiler chickens, currently one of the most discussed and...

1. Introduction Modern American agriculture has become successful in producing food security despite having less than 1% of the US population actually listing farming as their occupation [1]. The US Census of Agriculture estimates that 8.6 billion broiler chickens, 107 million turkeys, 96 million beef cattle, and 68 million pigs were sold for meat in 2007 with an additional 350 million laying hens and 79 million dairy cows producing eggs and milk [1]. Eighteen to 36 kg of manure...

Introduction Measures need to be taken in the Netherlands to reduce emissions of fine dust (PM10 and PM2.5) from major emission sources, including poultry houses with litter, to comply with European standards on maximum fine dust concentrations in the ambient air. The contribution of animal houses, especially poultry houses, to the total primary emission of PM in the Netherlands is estimated to be approximately 20% (CBS...

Good litter management and proper ventilation are critical to preventing footpad dermatitis (FPD) and maintaining health in poultry flocks. Footpad dermatitis first became an issue for the poultry industry in the 1980s, but it surely existed long before that time. The condition is known by a variety of names, including pododermatitis and contact dermatitis. It is characterized by inflammation and ulcers on the footpad and toes. The sores can be shallow or deep....

Poultry manure fertilizer contains all the essential nutrients required for crop production, and its value as an organic fertilizer and a source of plant nutrients has been recognized for centuries. Even with its beneficial effects on plant growth, however, manure constitutes only a small percentage of the nutrients applied to cropland when compared to commercial fertilizer. Poultry manure fertilizer is not used to its maximum...

1. Introduction The occurrence of ‘wet litter’ in meat chicken sheds is associated with concerns regarding animal welfare, flock health, food safety, environmental impacts and reductions in production efficiency. Mitigating wet litter will only be achieved when there is thorough understanding of the multidimensional causal factors. This will require a multidisciplinary approach to understand the hydrology in...
