AI Article Synopsis
- The study explored the effects of Aspergillus awamori (AA), fructooligosaccharide (FOS), and their combination on broiler chicks' growth and health.
- Results indicated that chicks receiving AA, FOS, or both showed significant improvements in body weight gain and feed efficiency compared to the control group.
- Additionally, these supplements positively impacted blood lipid profiles and enhanced the expression of growth-related genes, suggesting they promote better nutrient utilization and muscle protein metabolism.
Article Abstract
This study was conducted to show the effect of Aspergillus awamori (AA), fructooligosaccharide (FOS), and combined Aspergillus awamori and fructooligosaccharide (AA + FOS) on growth, digestibility, blood parameters, and expression of some growth-related genes. A total of 60 broiler chicks at the age of 15 d were divided into a control group (n = 15) and 3 treatment groups. The control group was fed a basal diet, and the treatment groups were fed basal diets supplemented with 0.05% AA, 0.05% FOS, and combined of 0.05% AA and 0.05% FOS. Results from measurement of growth performance and digestibility revealed a significant increase in the body weight gain with improved feed conversion rate in the experimental groups. Interestingly, dry matter digestibility (DMD) and crude protein utilization (CPU) were improved. In addition, plasma total cholesterol and low density lipoprotein-cholesterol (LDL-C) were decreased, while plasma high density lipoprotein-cholesterol (HDL-C) was increased by feeding AA, FOS, and AA + FOS. Expressions of growth hormone secretagogue receptor (GHSR), insulin-like growth factor 1 (IGF-1), and insulin-like growth factor 1 receptor (IGF1R) were increased in experimental groups. In conclusion, the supplementation of either Aspergillus awamori or fructooligosaccharide or both improves digestibility and growth performance probably by promoting skeletal muscle protein metabolism.

Article Synopsis
- Polygonatum kingianum, commonly known as Huangjing, is a traditional Chinese herb in the Asparagaceae family that has medicinal benefits, including promoting blood circulation and boosting immunity, but it is increasingly affected by root rot diseases.* -
- Recent studies have identified several fungal strains causing this root rot, with four isolates obtained, among which HJ-G6 was found to be the most pathogenic, exhibiting rapid growth and a large spore production.* -
- Morphological and genetic analyses concluded that HJ-G6 is likely Aspergillus awamori, a significant pathogen impacting Huangjing's yield and quality in regions like Sichuan and Guizhou.*

Article Synopsis
- The demand for enzymes like phytase is growing due to their applications in the food and animal feed industries, prompting a study on purified phytase from the longhorn beetle.* -
- The enzyme was successfully purified through various methods, achieving an 8.1-fold purification and demonstrating optimal activity at 70°C and pH 7 while maintaining significant activity across a range of pH levels.* -
- The study found that certain ions affected enzyme activity; some (like Ca and Cu) enhanced it while others (like Hg and EDTA) inhibited it, suggesting potential industrial applications for the uniquely sourced phytase.*
