Summary: This study demonstrated that E. tenella infection impairs feed efficiency and small intestinal health in broilers by reducing cecal VFA production and deepening cecal CD. Different inoculation levels modulate fecal moisture content and oocyst shedding tendencies, suggesting that energy supplementation or cecal microbiota modulation could potentially mitigate the negative effects of E. tenella infection.

Summary: Eimeria tenella infection induces autophagy in chicken embryo cecal epithelial cells. The expression of autophagy-related proteins is increased, while p62 protein levels are decreased. Chloroquine enhances autophagy, reducing E. tenella infection, while rapamycin induces autophagy and inhibits E. tenella infection. In contrast, 3-Methyladenine treatment increases E. tenella infection rate.

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: 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.
