Summary: This study analyzed the concentration of estradiol-17β in laying hens of different laying lines at different ages. The results showed that high-performing hens had higher estradiol-17β concentrations compared to low-performing hens. The highest concentration was observed at the 49th to 51st week of age, while the peak of laying intensity was observed at the 33rd to 35th week of age. Additionally, housing conditions influenced the estradiol-17β concentrations, with hens in cages showing higher concentrations compared to those in a floor housing system.

Summary: Eggs are a valuable source of nutrients and can be preserved using thermal and non-thermal techniques to reduce bacterial contamination. Thermal approaches are more effective in reducing the concentration of pathogens on the egg's surface. Combination methods, such as thermoultrasonification, can mitigate negative effects on the egg's functionality. Further research is needed on other decontamination methods for commercial usage and cost considerations.

Summary: Two sodalite phases, potassium sodalite (K.SD) and sodium sodalite (Na.SD), were synthesized and characterized for their potential in adsorbing PO43- from water. The sodium sodalite phase showed higher surface area, ion-exchange capacity, and PO43- sequestration capacity compared to the potassium sodalite phase. Both phases exhibited spontaneous, homogeneous, and exothermic adsorption reactions, following the Langmuir isotherm and pseudo-first-order kinetics. The sodium sodalite phase had a higher density of active sites and stronger adsorption capability, resulting in complete adsorption of PO43- from water in a shorter time.

Summary: Recently, nanoscale FeCoNi-ternary mixed metal oxides (TMMO) were used to activate persulfate (PS) for degrading pharmaceutical and personal care products (PPCPs). The FeCoNi-TMMO catalyst exhibited high catalytic activity, stability, and recyclability due to the synergistic catalytic effect between the transition metal elements. The FeCoNi-TMMO/PS system showed excellent universality for various PPCPs, and reactive oxygen species played a crucial role in the degradation process.

Summary: This study investigated the influence of adding natural zeolite to Japanese quail litter on microclimate parameters, growth performance, blood gases, and blood biochemical indicators. The results showed that both the treated group and the selected line had better growth performance compared to the untreated group and control line. Adding zeolite improved the microclimate characteristics of the quail litter, leading to better growth performance and health of the birds. Thus, the use of natural zeolite effectively reduces atmospheric ammonia levels in Japanese quail farms.

Summary: Natural kaolinite can be modified into separated single nanosheets (KNs) and scrolled nanoparticles as nanotubes (KNTs). The synthetic nanostructures show advanced oxaliplatin-medication (OXAP) delivery systems. The loading capacity of KNs and KNTs is significantly increased compared to raw kaolinite, and they exhibit classic kinetic and isotherm behaviors. The release of OXAP from KNs and KNTs shows continuous and regulated profiles, with KNTs demonstrating faster release. The cytotoxicity of the synthesized structures is significantly enhanced on cancer cell lines, and they greatly increase the cytotoxicity of OXAP.

Summary: The need for heat stress mitigation methods has increased due to climate change. Adding trace elements, such as selenium, to chick diets can improve production yield and grill productivity. However, there is limited knowledge on the use of organic selenium in heat-stress situations. This study found that adding organic selenized yeast to broiler diets improves their blood profiles and productivity under heat stress, suggesting that feed additives can reduce the impacts of heat stress on broilers.

Summary: In recent years, there has been an increase in the occurrence of fowl adenovirus 2 (FAdV-2) in China, posing a significant threat to the poultry industry. This study investigated the epidemiology, phylogenetic relationship, genomic characteristics, and pathogenicity of FAdV-2. The results showed that FAdV-2 was the most commonly detected serotype among various FAdV serotypes. Genetic analysis revealed that these FAdV-2 strains formed a distinct branch within the FAdV-D group and had a high nucleotide similarity with reference strains. Recombination analysis identified recombination events between FAdV-2 and FAdV-11 in some strains. Pathogenicity experiments demonstrated that a recombinant FAdV-2 strain caused a high mortality rate and more severe disease in chickens. These findings contribute to our understanding of FAdV-2 and provide a basis for vaccine development.
