Summary: This study investigated the development regulation of the uterine-vaginal junction (UVJ) epithelial folds in female birds and its crucial role in sperm storage and fertilization. The study classified the development of UVJ folds into 4 stages based on morphological characteristics. RNA-seq analysis identified different stages of regulation and genes involved in cell proliferation, differentiation, polarity, migration, adhesion, and junction during UVJ fold formation. The study also found significant differences between different cell types within UVJ, and highlighted the importance of genes in the TGF-beta and WNT pathways in regulating epithelium proliferation and differentiation for UVJ fold formation. This research provides new insights into the differential regulation of fertilization traits from a developmental biology perspective.

Summary: This study investigated the individual differences in fertilisation rates (FRs) using two populations of chicken laying breeders. Differences in fertilisation regulation were found by comparing the funnel and distal parts of the infundibulum. The results suggest that individual differences should be considered in the breeding process and the identified differentially expressed genes provide insights into fertilisation regulation.

Summary: This study analyzed the semen movement and sperm head size patterns of boar ejaculates using CASA systems. Significant differences were found in kinematic and morphometric variables between different sire lines, as well as in fertility-related variables of the maternal lines. Further investigation into the differences in kinematic and morphometric variables between sire and dam lines related to fertility is needed.

Summary: In this study, transcriptomic analysis was conducted on the uterovaginal junction (UVJ) of breeder hens to investigate the effects of heat stress. The results showed that heat stress suppresses the immune function of hens while increasing the expression of heat shock proteins (HSPs). These findings contribute to a better understanding of the impact of heat stress on the reproductive system of hens.

Summary: This study aimed to assess the effect of ejaculate collection frequency on semen output, sperm quality, and field fertility in young bulls. The results showed that collecting ejaculates more frequently significantly reduced the number of days required to obtain 1000 straws, increased semen quality in terms of lower superoxide production, and improved field fertility.

Summary: Excessive ROS production during sperm freeze-thawing can damage sperm quality, but supplementing Beltsville extender with 10 mM quercetin can significantly improve motility and membrane functionality of rooster sperm. This suggests that quercetin supplementation could be a beneficial method for enhancing the freeze/thaw characteristics of rooster sperm.

Summary: Research has shown that in birds, sperm from the dominant black (DB) strain has a better ability to enter the sperm storage tubules (SST), resulting in higher fertilization success. This may be due to the longer flagellum and midpiece of DB sperm, allowing them to swim faster in a high viscosity medium.

Summary: The asynchrony of sexual maturity in grouper sperm poses a significant limitation to reproduction. Cold storage is an effective method to address this issue, but prolonged storage leads to loss of sperm activity. The study found that cold storage impacts the transcriptome, proteome, and oxidation resistance of giant grouper sperm, affecting energy metabolism.

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.

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.
