Determination of Keratinase Activity using Chicken Feather DMSO extract and its optimization with Response Surface Methodology [PDF]

E3S Web of Conferences
Keratinase is an enzyme capable of degrading keratin, exhibiting two activities: protease activity, which cleaves peptide bonds, and disulfide reductase activity, which reduces disulfide bonds (-S-S-). However, keratinase activity is often measured using

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

Animal 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.

Heat Stress in Quail: Impacts on Health and Productivity, and Mitigation Strategies

Animal Research and One Health, EarlyView.
Heat stress disrupts physiological homeostasis in quail, inducing oxidative stress, immune dysregulation, and metabolic imbalance, which impair growth, reproduction, product quality, and welfare. Integrating nutritional, environmental, and genetic–epigenetic strategies enhances thermotolerance, sustains productivity, and supports climate‐smart quail ...

Keratin biofilm from chicken feathers

IOP Conference Series: Earth and Environmental Science, 2020
Abstract Keratin is an important biomaterial for industrial applications. About 90% of keratin is found in chicken feathers. Previous study showed that solid-state fermentation of keratinase by Bacillus sp. MD24 using chicken feathers a sole carbon and nitrogen source produced micro-keratin as a solid by-product.
