Poultry welfare
Proper animal welfare involves providing the proper housing, management, nutrition, disease prevention and treatment, responsible care, humane handling and, when necessary, humane euthanasia. These factors allow for the most optimal and humane growing environment. The concept of animal welfare includes three elements: the bird’s normal biological functioning, its emotional state and its ability to express its natural behaviors. Improving animal welfare can be accomplished through offerings like poultry feed enrichment, which can reduce stress, thereby increasing performance, productivity and profitability. Animal welfare is currently a major requirement for intensive poultry production. Beak trimming, stocking density, free access to feed, heat stress, and air pollutants became important issues, which are regulated in several countries. Animal welfare is observed by watching how birds naturally behave and even by looking at mortality stemming from aggressive behaviors.
American and European companies are pledging to move to include slow-growing broiler chickens for production, which means they will use broiler chickens with less efficient growth rates in their production systems. Slow-growing strains show improved welfare outcomes compared to conventional ones. This newsletter...

Is it safer to catch chickens by two legs or one? Poultry scientists show how tweaking catching and transport methods can reduce injuries.
In a recent study, poultry scientists investigated the best way for manually catching chickens in a production setting. The two main ways for manually catching a chicken are the one-legged catch and the two-legged catch. The researchers examined chickens after catching to see...

A new study of elevated plastic platforms vs. wooden planks suggests turkeys can balance better on the platforms and prefer platforms overall
Poultry scientists work to make sure animal housing is safe—and they research how housing updates might benefit bird health and welfare. For researchers in Switzerland, one important question is whether fattening turkeys (raised for their meat) might benefit from...

Conventional broiler (meat) chickens reach a final weight of 6.6 lbs (3 kg) in approximately 40-44 days. Across their lifetime, these fast-growing birds gain an average of 68-75 g per day, with daily gain increasing with age (Aviagen, 2022; Cobb, 2022). With their fast growth, however, they...

Interest in plastic evaporative cooling pads has been steadily increasing since their introduction approximately ten years ago, especially for producers with water quality issues. Though for the most part six-inch plastic pads are interchangeable with six-inch paper pads, and can produce similar cooling, this doesn’t mean there are not significant differences between plastic and paper pads. Not taking into account these potentially important differences can result in an increased...

The poultry husbandry landscape in the United States is rapidly evolving in response to public concern related to animal welfare. As the production systems become complex and the flock sizes increase, conventional welfare assessment methods can be inadequate. Technology can help us in that regard by reliably...

Background & Objectives There has been immense growth in the global poultry industry that should be maintained to match the current preference of consumers for animal protein. Such growth also calls for a better understanding of factors that could influence production such as litter. Ducks spend their entire rearing period in contact with the litter material provided. It is therefore vital to investigate the effect that the different commercially available bedding materials...

Water meters are used as a management tool to track daily water usage in poultry houses. Most mechanical water meters used in poultry housing can only measure water flow rates more than 0.25 gals/min which limits reliable measurement of water usage for birds that are less than four days of age. Producers can now accurately measure water usage within minutes of chicks being placed in the house by using ultrasonic water meters. Modern house controllers can collect, store, and graph water...

Broiler chickens show better growth and reduced liver problems when given brown seaweed extract or meal during times of heat stress
Chickens don’t do well in the heat. In fact, birds experiencing heat stress tend to eat less, grow slower, and even have compromised immune function. Heat stress is also a major cause of mortality for chickens and leads to considerable economic losses each year in the poultry...

Poultry scientists show that a few hours of darkness a day does not harm broiler chicks
Broiler chicks can be provided between 1 to 4 hours of darkness a day without negative consequences, according to a recent study led by scientists at the USDA Agricultural Research Service and Auburn University.
Their findings, published in The Journal of Applied Poultry Research, address the practice of rearing chicks with constant light during their...

When placing chicks it is crucial to their future performance and health to make sure the litter they are placed upon has been thoroughly warmed. Though the air in a house can be heated relatively quickly, insuring the litter throughout a brooding area is heated to between 85°F and 95°F can take from 12 and 36 hours depending on the type of heating system, level of air movement, house tightness, litter moisture level, etc. Since the chicks are in constant contact with the litter,...

1. Introduction Deoxynivalenol (DON) is a secondary toxic metabolite mainly produced by Fusarium species that belongs to the trichothecenes family. DON frequently occurs in cereals, including wheat, maize, barley, rye and oats [1]. A 10-year survey from 2008 to 2017 of the global mycotoxin occurrence in feed revealed that DON was the most prevalent of mycotoxins and was detected in 64% of 74,821 samples collected from 100 countries [2]. Therefore, DON is considered to be...
