Summary: This study reveals significant differences in cecal microbial community structure, tissue neurochemical concentrations, and gut structural morphologies between birds with different corticosterone responses to stress. Unique neurochemical changes in the intestine following stress suggest a potential relationship between the cecal microbiome and overall avian physiology.

Summary: Plastic pollution poses a threat to birds, and little is known about the sublethal effects of ingested microplastics (MP) and the effects of MP <1 mm in birds. This study evaluated the toxicity of environmentally relevant polypropylene and polyethylene particles collected in the Norwegian coast in growing Japanese quail, and found size-dependent sublethal effects of MP.

Summary: This study demonstrates that during photorefractoriness, testicular apoptosis occurs in Japanese quail causing reproductive stress. Withania somnifera root extract helps overcome stress and improve reproductive performance by increasing expression of ir-ER alpha. Furthermore, the stress ameliorating effect of WSRE in reducing apoptosis mediated by ir-Caspase-3 and ir-p53 in the testes is evident in Japanese quail.

Summary: The COVID-19 pandemic has exposed healthcare workers to traumatic situations that may lead to the development of posttraumatic stress disorder (PTSD). This study found that an important factor for PTSD is the peritraumatic tonic immobility (TI) reaction. Healthcare workers who reported high TI scores had a significantly higher probability of having a PTSD diagnosis. TI should be screened and psychoeducation about its biological nature should be introduced.

Summary: The study aimed to investigate the effects of heat stress on lipid oxidation and antioxidant enzyme activity through 10 generations of selection for low feed conversion ratio in Japanese quail. The results showed that selection for low FCR and heat stress at 31.1 degrees C did not significantly affect lipid oxidation and antioxidant enzyme activities across all tissues.

Summary: Tonic immobility (TI) is a temporary, involuntary state of motor inhibition that occurs in intense fear, particularly among victims of sexual violence. This literature review examines research on TI in women victims of sexual violence. The study identified 11 manuscripts meeting the criteria, which describe TI as characterized by fear and immobility. Quantitative research confirms the presence of paralysis and fear in TI, which leads to physical and mental paralysis, trembling, inability to vocalize, and eye closure. Furthermore, TI is associated with long-term negative clinical implications such as post-traumatic stress disorder. Recognizing TI is crucial for legal and care practitioners to understand victim behavior, differentiate consent, and assist in their recovery.

Summary: The objective of this study was to determine the ideal arginine intake for egg production in Japanese quail. The study found that the arginine levels in the diet significantly affected the quail's responses, with egg production increasing from 10% to 97% when the arginine level increased from 0.361% to 1.311%. The models estimated the ideal arginine intake for egg output to be 290 mg/quail per day or 1,411%.

Summary: This study aimed to test a diverse group of chicken breeds to search for breeds that experience less fear. The results showed significant variations in fear-related behaviors among different breeds, possibly linked to their historical purposes. Understanding and quantifying these behavioral responses provide opportunities to improve welfare through selection and future breeding.

Summary: Tonic immobility is a passive antipredator strategy used by green lacewing larvae to decrease mortality. This strategy is influenced by energetic state and genetic predisposition, with food deprivation increasing the likelihood of tonic immobility and genetic variation contributing to individual differences. Energetic stress plays a significant role in the use of tonic immobility, but there is also a genetic component that influences this behavior.

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.

Summary: The study investigates the effect of Eimeria infection on gastrointestinal physiology, growth performance, and egg production of Hy-Line W-36 laying hens during peak production. Results show that Eimeria infection negatively affects body weight, feed intake, immune response, and nutrient transporter gene expression. Egg production temporarily ceases in hens infected with high and medium-high dosages of Eimeria.

Summary: This study evaluated the effects of CP and ME on the performance and nutritional value of Japanese quail lay chicken. The results showed that protein and energy levels significantly influenced all productive outcomes except feed conversion ratio. The combination of dietary energy and protein levels had a substantial effect on all egg quality trials evaluated. It is recommended to feed layer Japanese quail between the ages of 8 and 20 weeks during the summer with a dietary energy content of 2,900 kcal ME/kg and 20% CP.

Summary: The study investigates the functional variants associated with chicken eggshell color in the SLCO1B3 gene by measuring the eggshell color of Lueyang black-boned chickens and analyzing the genetic data. It identifies 15 variants in SLCO1B3 that are significantly associated with eggshell color. However, the functional analysis shows that one specific variant, 1B3_SNP108, does not have a significant effect on promoter activity. This study highlights the importance of SLCO1B3 and its variants in breeding eggshell color.

Summary: This study investigated the welfare and health of laying hens in a multitier system. The results showed that the spatial distribution of hens changed with increasing age, and lower-ranking hens preferred to stay in lower tiers to avoid competition but still had access to resources. This improved the welfare and health of the hens near the end of the laying cycle.

Summary: This study examined the effect of risk perceptions on preventive behavior among vendors in the live poultry wholesale market and the live poultry retail market in Guangdong Province using the health belief model and structural equation modeling. The results showed that perceived severity and perceived benefits positively influenced vendors' self-efficacy in the wholesale market, while perceived barriers negatively affected self-efficacy in both the wholesale and retail markets. Moreover, cues to action mediated the relationship between perceived severity, perceived benefits, and self-efficacy, and also mediated the effect of perceived susceptibility among wholesale market vendors.
