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.

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.

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.

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.

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.

Walking on eggshells — Assessing anxiety in chickens

Anxiety is the most common mental health disorder in people. Chickens may also experience anxiety, but it is difficult to measure and research has been mainly focused on assessing fear. However, we can get insight into their mental state based on observations of behaviors.

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.

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.
