On-site testing of avian influenza in the poultry industry

Time is the most critical element when it comes to managing avian influenza outbreaks. While surveillance is key in minimizing outbreaks, no tests currently exist that allow for quick, on-site testing. In an attempt to create a simple, cost-effective system for testing, scientists at the University of the Guelph’s BioNano Laboratory developed a colorimetric system enabled by nanotechnology that can quickly detect disease-related pathogens through the naked eye.

Efficiency and safety of using black soldier fly larvae in laying hen feed

Solutions for protein-rich, sustainable and efficient feed for hens are becoming increasingly important as the egg industry continues to grow. Researchers have found that insect larvae contains protein and fat content that could be used as an alternative in animal feed. One of the insects that can convert large amounts of vegetable waste into protein-rich larvae is the black soldier fly—a wasp-like fly native to the Americas.

Water quality effects on laying hen performance

Today’s hens produce significantly more eggs compared to hens 50 years ago. While many factors play a role in high-quality egg production, the role water quality plays in this process is relatively unknown. As such, researchers at Dalhousie University sought to study the effect that water quality has on laying hen performance today, taking into account the diversity of water found across Canada.

Eggs for breakfast: Exploring satiety and energy intake control in children

Studies have shown that when kids eat breakfast, they have better appetite control, better diet quality, and better weight control. With childhood obesity on the rise, identifying foods that can help regulate appetite and promote satiety (feelings of fullness) can inform effective prevention and treatment tools.

Nutritional benefits of eating eggs with raw vegetables

Dietary guidelines advise us to eat large portions of fruits and vegetables, but on average, we are not eating enough. Eating fats can increase the body’s absorption of carotenoids. As such, this study sought to assess how carotenoid absorption is affected when cooked whole eggs are consumed with a carotenoid-rich, raw vegetable salad.

Benchmarking the prevalence of keel fractures in conventional and floor-housed laying hens

Understanding the benefits and trade-offs of housing systems is an important component of improving animal welfare, and providing information as farmers re-tool their operations and install new housing systems. This study aimed to benchmark and compare some animal-based welfare indicators in flocks housed in conventional systems and non-cage single-tier floor systems, focusing primarily on keel bone fractures.
