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.
Footpad dermatitis is a common problem in poultry. Severe cases of footpad dermatitis have a negative impact on animal welfare as well as on the commercial result of broiler units. The quality of the litter is unquestionably a major impact factor on the development of footpad dermatitis. A combination of wet litter and unspecified chemical factors in the litter are thought to be the major cause of the footpad dermatitis. Beside...

Dear All, I have visited a big farm in Peru, La Callera, using Layer Manure to feed layers. The level was more than 5%. My questions are the following: 1. Do you have the experience of the use of poultry manure to feed poultry? 2. What is nutritional values of the Layer manure? 3. What are the risk for Layers and consumers? 4. Which could be the maximum level? Thank you ...

INTRODUCTION
Because wet litter impacts broiler welfare and performance it is of vital importance to poultry producers. Wet litter in poultry houses may be caused by a number of factors including mycotoxins, disease, gut health, nutrition, management, housing and environment. Nutrition, including reducing mycotoxin contamination of feed, plays an important part in controlling litter moisture....

Introduction Footpad dermatitis (FPD), also called footpad lesions or pododermatitis, is a major welfare concern in broiler chickens. Severe FPD is likely to be painful for the birds, and because of its association with litter quality it also reflects other welfare aspects (Haslam et al. , 2007).Wet litter is the most important factor causing FPD in broiler chickens (Shepherd et al. 2010). It can be...

The sublimation of a simple substance or of a chemical compound is its transition from a solid state to a gaseous state without passing through the liquid state. In modern language this term is also generically used to indicate the opposite process, where the term de-frosting or inverse sublimation would be more correct. At times, certain insects can be seen walking on water and as is known it is possible to make a metal clip...

Summary A feeding study was conducted to compare the effects of litter material, dietary fibre and sex on growth performance, organ development, mucosal morphometry and gut microbial communities in broilers. Seven hundred twenty day old Cobb chicks were allocated to 24 floor pens in a 2 x 2 x 2 factorial design with 3 pens of 30 birds per replicate (3 pens of males and 3 pens of females). Factors were: litter material, paper or hardwood shavings; dietary fibre,...

Poultry farmers are consistently looking at ways to reduce costs, increase farm efficiencies and maximise their return on investment. For many, the management of poultry litter is one aspect of their operations that presents its own challenges. For fertiliser use, spent litter is commonly perceived as bulky, having an inconsistent nutrient content, and there are concerns that use as a land applied fertiliser may result in environmental damage due to nutrient...

A major component of broiler management is maintaining good litter quality throughout the flock. Litter quality is negatively influenced by moisture. As litter moisture increases, litter quality decreases. Factors that affect litter moisture include drinker management, bird health, bird density, ventilation rates, litter depth and litter type. Typically broiler facilities are bedded with materials that have moisture content less than 10%. Under...

INTRODUCTION Animal husbandry suffers from losses due to contamination with pathogenic bacteria. Their resultant impacts in animals include lower weight gains and increased mortality. Banning the use of in-feed antibiotics (AGPs) in livestock, as has happened in the EU, placed more pressure on animal producers and feed millers. In this context, organic acids have long been used to counteract gram-negative pathogenic bacteria in animal feed; and...

Definition: Aluminum sulfate (alum) is added to poultry litter in the poultry house to reduce ammonia volatilization. Purpose: Over half of the nitrogen excreted by chickens is lost to the atmosphere as ammonia before the litter is removed from poultry houses. Research has shown that alum additions to poultry litter greatly reduces ammonia emissions. Lower ammonia levels in poultry houses...

In the late 1950´s it took approximately 50 days for a male broiler to reach a weight of 1.7 lbs. By the early 2000´s the same weight could be reached at 21 days of age (Havenstein, et. al, 2003). Today it can be reached in as little as 18 days. One of the many challenges of managing today´s fast growing broilers is maintaining proper litter quality. In general, a fast growing bird consumes feed at a higher rate than a slower...

Introduction Alphitobius diaperinus (Panzer), popularly known as "cascarudo" [thick-shelled beetle] (Rohde et al., 2006), belongs to the phylum Arthropoda, class Insecta, order Coleoptera and Family Tenebrionidae (Paiva, 2000). It is a pest of stored grain that has adapted to poultry houses (Vaughan et al ., 1984; Arends, 1987; Mac Allister et al ., 1995). It affects poultry...

Abstract Poultry litter becomes wet when the rate of water addition (urine/faeces/spillage) exceeds the rate of removal (evaporation). Anti-nutritional factors, toxins, pathogens and nutrient imbalances may cause wet litter directly by altering normal digestive physiology or indirectly by disturbing normal gut ecology. Poor quality ingredients and those with excess oligosaccharides or minerals can cause a...

Alphitobius diaperinus is one of the most predominant poultry litters inhabiting insect species all over the world. This insect has been shown to be able of transmitting a large variety of poultry pathogenic organisms (Newcastle virus, IBD virus, influenza virus, salmonella spp, clostridium perfergins and aspergillus spp). In this experience, we have studied the spatial distribution and the population fluctuation of Alphitobius diaperinus in a broiler house...

A recent Poultry CRC study has shown that broilers raised on fibrous litter are generally more uniform in feed consumption, Feed Conversion Ratio (FCR) and, most importantly, body weight. This potentially greater uniformity holds the promise of less out of specification birds at the processing plant.
Moreen Ali, Laboratory Manager at Inghams, undertook comparative studies of the productivity and health of broilers raised on rice hulls, softwood sawdust, pine shavings, re-used single...
