New study shows brain size is smaller in commercially bred laying hens

When humans domesticate and breed an animal, they tend to select for a very specific trait. In laying hens, artificial selection for high egg production has led to hens that can produce 320 eggs a year. But could artificial selection have unintentionally altered hen brain morphology?

Stocking density and broiler behavior

Stocking density is a key determinant of profits from a broiler operation as revenues per unit of space increase with increasing stocking density. However, overcrowding due to high stocking density can lead to negative behavior and welfare consequences.

Management, vaccines are keys to fowl cholera prevention

Fowl cholera is a bacterial disease of poultry that commonly affects chickens around 15 weeks of age and older, but it can impact birds as young as 6 weeks, cautions Charlie Broussard, DVM, Merck Animal Health.

10 steps for successful fowl cholera vaccination

Developing a thorough vaccination strategy for fowl cholera — one that includes selecting the right vaccine strain for the field challenge that the birds are facing and proper vaccine administration — is critical when managing this bacterial disease.

Bioluminescence shows vertical transmission of S. Reading in turkeys

A multistate salmonella outbreak in the US due to the consumption of contaminated turkey products spurred a joint effort between the Centers for Disease Control and the turkey industry to identify an untraditional serotype of Salmonella, S. enterica serotype Reading (S. Reading).

Understanding post-vaccination ‘takes’ critical for managing fowl cholera

Vaccination is key to managing fowl cholera in poultry. For a program to be successful, however, it’s critical to train vaccination crews to monitor vaccine “takes” or major cutaneous reactions within a flock — no easy task with today’s employee shortages and rotating vaccination crews.

Food labels, claims and animal welfare

Various claims and labels on the products provide consumers with information about how the animals were raised and treated during production. However, the information on animal products can sometimes be confusing.

Starting off right: Ensuring chick welfare

The first few days of life are some of the most important in chicks' lives. During this time, chicks start developing and set themselves up for the rest of their lifetime. The husbandry decisions made at this point can impact the birds' growth, development, health and welfare.

Tryptophan: The link between poultry welfare & nutrition

Tryptophan is an essential amino acid, 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. A tryptophan deficiency could affect behavioral responses to stress in poultry.

Cold temperatures can have severe consequences for poultry health and welfare

The consequences of cold stress can be severe, leading to death in extreme cases. A chicken's susceptibility to cold stress depends on various factors, including the chicken's breed, age, body size, amount of feather coverage and condition of the feathers and nutritional status.

Sustainable eggs: A new approach hatched in Indiana

There’s a new egg on the block in the US — the carbon-neutral egg from Kipster Farm. It’s the result of a different approach to egg farming that started in 2017, when Kipster, a Dutch egg producer, introduced the world’s first carbon-neutral egg to the Netherlands.

Poultry scientists test promising avian flu vaccination strategies

Avian influenza outbreaks in the US are rare but, when the virus strikes, the results are devastating. The disease spreads rapidly, forcing producers to rely on quarantine-and-cull to limit the damage. A 2015 outbreak in the US led to an estimated loss of more than 48 million birds.

Transforming data into information that makes poultry healthier

Veterinary data play a critical role in not only analyzing poultry health but also implementing long- and short-term strategies to improve health and prevent disease. However, several challenges present roadblocks to capturing and interpreting these data.

Don’t overlook the basics when using coccidiosis vaccines

Most poultry producers today use vaccines to help manage coccidiosis. Live coccidial vaccines are designed to uniformly infect birds with a controlled number of Eimeria oocysts to stimulate a protective immune response, but not all vaccines are the same.

How phytogenic feed additives can benefit poultry production systems

From supporting poultry health to improving bird growth and production efficiencies, phytogenic feed additives can offer a range of benefits to poultry production systems. Megan Koppen, US poultry technical manager with Cargill, explains what phytogenics are and why they can be a valuable addition to broiler, layer and turkey diets.


New non-invasive assay for C. perfringens helps monitor NE in poultry

Necrotic enteritis (NE) is a devastating disease characterized by severe gut inflammation and sudden death, which can lead to significant economic losses. A new instrument from Ancera can help identify Clostridium perfringens, the causative agent of NE, early enough to help producers treat or prevent NE.

Human-animal interactions : Impacts on animal welfare

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. However, fearfulness as a trait still persists and domestic animals often perceive human encounters as fearful.

Researchers identify early indicators of necrotic enteritis in broilers

In this age of “no antibiotics ever” farming, the re-emerging necrotic enteritis (NE) disease caused by Clostridium perfringens poses a major economically important health concern in poultry, particularly in broiler flocks, says Ravi Kulkarni, BVSc, assistant professor at North Carolina State University.
