Fasting and Refeeding Mediated Phospholipid Remodeling Plays an Important Role in Improving Meat Quality of Aged Laying Hens

open access: yesAnimal Research and One Health, EarlyView.
ABSTRACT This study explored fasting‐induced physiological remodeling effects on meat quality in aged laying hens. Fasting for 15 days (F15) significantly reduced abdominal fat, intermuscular fat width, subcutaneous fat thickness, and liver index versus pre‐fasting (F0) (p < 0.05), which recovered post‐refeeding.

Building a Bird: Musculoskeletal Modeling and Simulation of Wing-Assisted Incline Running during Avian Ontogeny [PDF]

open access: yes, 2018
Flapping flight is the most power-demanding mode of locomotion, associated with a suite of anatomical specializations in extant adult birds. In contrast, many developing birds use their forelimbs to negotiate environments long before acquiring “flight ...

Heat Stress and Gut Microbiome Dynamics in Poultry: Interplay, Consequences, and Mitigation Strategies

open access: yesAnimal Research and One Health, EarlyView.
Heat stress disrupts gut microbial balance in poultry, impairing nutrient absorption and immunity. This review outlines the interplay between thermal stress and microbiome dynamics and discusses integrative mitigation strategies, probiotics, phytogenics, cooling systems, and genetic adaptation to enhance poultry resilience.

“We might be put into situations we are uncomfortable with, but not exactly told how to deal with them”: Health professional students' experiences questioning low‐value care practices during work‐integrated learning

open access: yesAnatomical Sciences Education, EarlyView.
Abstract Health professions students often observe and practice alongside supervising health professionals during work‐integrated learning (WIL) to develop essential capabilities. While students may encounter practices they interpret as low‐value care during WIL, many hesitate to question or challenge these practices.
