Objective: The aim of this study was to characterize the fecal microbiota of broiler chickens reared in the presence of different shades of light-emitting diode (LED) lights, correlating this information with biochemical and molecular evidence that allowed drawing conclusions on the state of health of the animals.
Methods: Overall, the metagenomic approach on fecal samples was associated with evaluations on enzymes involved in the cellular response to oxidative stress: glutathione peroxidase (GPX), superoxide dismutase and catalase; while the inflammatory aspect was studied through the dosage of a proinflammatory cytokine, the interleukin 6 (IL-6), and the evaluation of the matrix metalloproteinases 2 (MMP-2) and 9 (MMP-9). Specifically, analysis was performed on distinct groups of chickens respectively raised in the presence of neutral (K = 3,300 to 3,700), cool (K = 5,500 to 6,000), and warm (K = 3,000 to 2,500) LED lightings, and a direct comparison was performed with animals reared with traditional neon lights.
Article Synopsis
- The study examined how different LED light color temperatures (Neutral, Warm, and Cool) affect the quality of breast meat from AZ Extra Heavy Red chickens compared to traditional neon lighting.
- Results showed that Neutral LED raised cooking loss in meat, while Cool LED improved the levels of healthy monounsaturated fatty acids and altered volatile compound profiles.
- The findings suggest that LED lighting significantly influences the meat's chemical properties, but further research is required to assess potential impacts on taste and consumer preferences.
Article Synopsis
- Knee muscle atrophy and weakness are common issues following ACL reconstruction, and blood flow restriction (BFR) training is a new method being explored for treatment, although evidence on its effectiveness is currently limited.* -
- A systematic review evaluated studies comparing BFR training to conventional therapy, focusing on knee muscle morphology and strength in ACL-reconstructed patients, finding that out of six studies, some showed favorable outcomes for BFR training.* -
- The findings suggest that while BFR training may improve muscle size and strength, the overall evidence is inconsistent and of limited quality, leading to a grade B recommendation for its use in clinical practice.*
Article Synopsis
- Agro-industrial by-products, like olive leaves, are gaining attention as dietary supplements in livestock for improving the quality of animal products.
- This study focused on lactating goats and analyzed their blood transcriptome after feeding them a diet supplemented with 10% olive leaves, revealing a downregulation of a specific gene (APOBEC2).
- Results indicated that the goats had lower cholesterol levels in both their blood and milk, suggesting that olive leaf supplementation could enhance animal welfare and provide health benefits for consumers.
