Green synthesis of zinc oxide nanoparticles utilizing extract from leaves: Characterization and optimization of calcination temperature.

Objective: This study aims to synthesize eco-friendly zinc oxide nanoparticles (ZnO NPs) by utilizing leaf extract and assess the characteristics of ZnO NPs produced throughout different calcination temperatures (300°C, 400°C, 500°C, and 600°C).

Materials And Methods: An evaluation was conducted to analyze ZnO NPs using an aqueous extract of leaf bioreductor at different calcination temperatures. The analysis involved the use of a particle size analyzer (PSA), a scanning electron microscope (SEM), energy dispersive X-ray (EDX), X-ray diffraction (XRD), and Fourier transform infrared (FTIR) spectroscopy.

Optimization of solvent and extraction time on secondary metabolite content of mangosteen leaf ( L.) as a feed additive candidate on poultry.

Objectives: This research aimed to determine the optimum type of solvent and extraction time to produce secondary metabolites (phenolics, flavonoids, tannins, and antioxidants) from mangosteen leaves ( L.) as feed additive candidates for poultry.

Materials And Methods: This research used a completely randomized design with a 2 × 5 factorial design with three replications.

Dietary Phytogenic Extracts Favorably Influence Productivity, Egg Quality, Blood Constituents, Antioxidant and Immunological Parameters of Laying Hens: A Meta-Analysis.

The present study aimed to assess the impact of dietary phytogenic extracts on laying hen productivity, egg quality, blood constituents, antioxidant, and immunological parameters through a meta-analytical approach. A total of 28 articles (119 data points) reporting the influence of dietary phytogenic extracts on the productive performance, egg quality, blood constituents, immunological, and antioxidant parameters of laying hens were embedded into a database. Statistical analysis was performed using a mixed model, with different studies treated as random effects and phytogenic extract levels treated as fixed effects.

The effect of different types of selenium injection on the immunity, villi surface area, and growth performance of local chickens.

Background And Aim: The presence of free radicals may lower chicken's performance. Thus, the antioxidant defense is needed and can be made through a nutritional approach such as selenium supplementation before hatches. This study aimed to investigate the type of selenium that, as an feeding (IOF) material, can provide the most enhancement of immunity, villi surface area, and early growth performance of local chickens.
