Ceva producing aMPV experimental autogenous vaccine using US-origin isolate

Ceva Animal Health has started antigen production for an experimental autogenous vaccine to fight the emerging avian metapneumovirus (aMPV) disease.

Behavioral needs of chickens: Dustbathing

Dustbathing occurs in all commercial chicken housing housing systems, even in caged systems with no substrate. But why do chickens dustbathe?

Identifying and managing late-stage E. coli mortalities in layers

When weekly mortality rates in layer flocks older than 50 weeks start creeping up over 0.3%, producers and veterinarians should be suspicious. According to Eric Gingerich, DVM, Cargill’s Diamond V, these numbers could indicate the presence of Escherichia coli.

Egg-laying-hen housing systems: What does the gut say?

Change is constant and there’s always a learning curve. Such was the case around 2017, as pressure built toward more cage-free housing systems for egg-laying hens along with the push to reduce antibiotics or antibiotic substances in animal diets.

Prebiotics, probiotics reduce negative effects of heat stress on layers

Laying hens exposed to prolonged heat waves experience adverse health effects that lead to health issues and reduced productivity. Many studies show that probiotics improve intestinal integrity due to lactic acid production and the competitive exclusion of pathogens.

Using non-invasive technology to reveal links between layer body condition, egg production

A technology from Cargill may overcome a barrier the layer industry has faced in understanding the nutrition and performance of its flocks, paving the way to reduced feed costs and higher egg production through better nutrition.

Alternative housing for laying hens: Access to outside

Housing systems for laying hens in the United States (and more broadly across the world) are transitioning away from conventional cages to cage-free systems.

Report looks at best practices for preventing floor eggs in cage-free layers, breeders

The first comprehensive literature review in 40 years presents up-to-date research and best practices to prevent floor egg laying.

Study suggests potential to reduce dietary amino acid intake in pullets

Today’s pullets are bred to reach sexual maturity sooner, are more efficient once they reach the egg-laying stage and remain productive longer than layers of past years. Those are all positives for egg producers, but is the industry keeping pace with their protein needs?

Ultrasonic water meters provide easy monitoring, early problem detection

Ultrasonic water meters enabled rapid and early identification of potential problems in cage-free layer houses, including feed shortages and water restrictions, according to research presented at the 2024 IPSF by William Strickland, graduate research assistant, University of Georgia.

NCSU: Environment, genetics affect egg production in a cage-free system

Consumers, retail customers and even legislators in some states are embracing cage-free egg production, necessitating a shift in the laying-hen industry.

Study finds dual ILT vaccination provides ‘most robust protection’ in long-lived birds

Poultry farms seeking protection against infectious laryngotracheitis (ILT) outbreaks may find the best defense for layers and broiler-breeder replacement birds is a dual ILT vaccination program.
