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.
Dust found in poultry housing is a complex substance most likely comprised of a mixture of excreta, feather, feed and bedding material. Exposure to poultry dust can impair the health of both poultry and poultry farmworkers as it serves as a medium for survival and spread of pathogenic microorganisms and inhalation of respirable particles and toxins (Just et al. 2009; Viegas et al. 2013). It has also proven useful as a population level sample material for tracking pathogen incidence and...

INTRODUCTION Broilers and turkeys are traditionally kept under monotonous environmental conditions, which compromise bird welfare due to inactivity, restriction of the behavioural repertoire and various health hazards. Recent development of welfare labels request enrichment devices in order to stimulate the expression of a wide spectrum of behaviours and to improve the physical and psychic conditions of the birds. Consequently there has been a rapid development of studies...

In 2020, the poultry industry had a combined value of over $35.5 billion in the United States. Of that, $21.7 billion came from broiler chicken production (USDA-NASS, 2021). Over 9.22 billion broiler chickens were raised and brought to market though the year, making it the largest and most valuable sector of U.S. poultry production. With such...

INTRODUCTION Although rearing the meat poultry in cage systems has recently attracted a lot of attention, however, some of the meat poultry stocks particularly broiler chicken still grow up on the floor of the poultry houses with a substrate known as litter material as poultry bedding. The recent trend in poultry industry has increased the demand for litter materials. Litter serves a number of important functions, such as absorbing moisture of excreta, reducing contact between...

Something to consider. If we preheated and ventilated a house long enough prior to chick arrival, the need for a litter treatment would be drastically reduced, if not possibly eliminated. Litter treatments are used primarily because the cost of preheating and ventilating a house long enough prior to chick arrival to remove excess moisture...

The level of ammonia young chicks will be exposed to during the first week of their lives is determined to a large extent by what was done to the litter between the flocks. Towards the end of a flock, the birds are adding thousands of gallons of water to a house each day. During cold weather, reduced ventilation...

Windrowing has become a very popular method of managing litter between flocks. In order to get the most benefit out of windrowing, the litter needs to be relatively damp. How damp? Ideally, the litter moisture content would be between 25 and 35%. At this level of litter moisture, when you grab a handful of litter and squeeze it, it would...

The deep litter method is one sustainable method of managing chicken litter in the poultry farming that many small poultry entrepreneurs use.
In the deep litter method, farmers get following benefit:
It does not take a lot of time to manage.
It ends up into compost manure - the high nitrogen manure is "Green".
Devoid of cage...

Introduction According to the FAO, livestock is one of the fastest growing sectors of global agricultural production. It is evolving in response to the rapid increase in demand for products of animal origin, especially in developing countries. In developed countries, through intensification practices that have helped increase yields and efficiency while bringing down costs, the demand for livestock products is stagnating and have to face many...

Method details Salmonella spp. cause fowl typhoid and pullorum diseases in poultry and are responsible for nontyphoidal Salmonella infection in humans. Prevention of Salmonella infection in chicken flocks is an important step in reducing salmonellosis outbreaks in humans. Vaccination with live attenuated vaccine of certain strains such as e.g. S. Enteritidis, S. Typhimurium and S. Gallinarum has been commonly used in the field to prevent the disease, and proven to be useful to...

1. Introduction Antimicrobials are routinely used to treat clinical livestock diseases, as well as to control common disease events, or even as animal growth promoters [1]. Though the latter use is not allowed in many countries worldwide, in some still continue using them for prophylaxis and as growth promoters’ purposes [2,3]. Tetracyclines and sulfonamides are some of the most frequently used antimicrobial classes in animal production throughout the world [4]....

INTRODUCTION Salmonella is a foodborne pathogen of great concern, and often, Salmonella outbreaks are found to originate from poultry (CDC, 2018; CDC, 2019). Every year in the United States, Salmonella is responsible for causing 1.35 million infections, >25,000 hospitalizations, and >400 deaths, and the majority of these illnesses are attributed to food (CDC, 2020). Salmonella's major risk factor in poultry meat and table eggs is its presence in live birds (Hugas and...

Due to the projections of accelerated growth of world population, it is essential to increase the production of proteins from animal and plant origin. Insects have been used as an alternative protein source for humans (entomophagy) and other animals because of their greater efficiency in food conversion and less environmental impact (Van Huis et al. 2013, Van Huis 2013, Van Huis 2020). Edible insect larvae contain an average of 54% protein, including essential amino acids and vitamin...

1. Introduction Contact dermatitis is an inflammation and irritation of the skin due to contact with an irritant or allergen. A common type of contact dermatitis in broiler chickens is footpad dermatitis (FPD), with necrotic lesions on the plantar surface of the central footpad [1]. When these lesions are left untreated, and environmental conditions remain the same or deteriorate, lesions will worsen, eventually encompassing the entire footpad, including the toes [2]. The...
