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.
Tryptophan, Serotonin & Melatonin Tryptophan (Trp) is an essential amino acid (AA), which is the building block of protein, therefore it cannot be synthesized by the body itself and must be obtained through food; it is important for many metabolic functions. Trp supplementation improves...

Piling is an abnormal behavior commonly observed in commercial laying hen flocks. Piling occurs when birds crowd together, usually on top of one another, in a densely packed manner. A piling event may or may not end in smothering. Smothering occurs when one or more birds die due to suffocation from piling. Piling and...

Human-animal interaction is the mutual and dynamic relationship between a human and an animal where the animal perceives human interaction as degree of relatedness or distance and vice-versa. Human beings have domesticated poultry species for eggs and meat production. Domestication has favored tameness in animals, however,...

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...

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...
