Summary: The study revealed that opportunistic pathogens proliferated significantly in Muscovy ducklings infected with MDRV. The immune system of the host actively combats the infection of gut microbes. The interaction between MDRV, intestinal bacteria, and host immune system was analyzed, providing insights into the mechanism of intestinal immunosuppression caused by MDRV.

Summary: This study investigated angiotensin-converting enzyme inhibitory peptides (ACE-IPs) derived from Muscovy duck plasma hydrolysate (MDPH). The crude ACE-IPs were separated and purified using ultrafiltration, gel chromatography, and reversed-phase high-performance liquid chromatography (RP-HPLC). The components with the highest ACE inhibition potential were selected for identification. The peptide VALSSLRP showed high ACE inhibitory activity (91.67 +/- 0.73%) due to its tight binding to the S1 ' pocket and formation of 3 hydrogen bonds. This study provides new information about the generation of ACE-IPs from duck blood plasma.

Summary: This study aimed to develop a comprehensive approach using machine learning models to assess fresh ejaculate from Muscovy duck drakes, combining sperm kinetics with non-kinetic parameters such as vitality, enzyme activities, and total DNA methylation. The samples showed significant differences in motility, curvilinear velocity, linear velocity, amplitude of lateral head displacement, beatcross frequency, and live normal sperm cells between different classifications based on progressive motility and DNA methylation features. Integrating nonkinetic parameters into machine-learning-based sample classification offers a promising approach for selecting high-quality duck sperm samples.

Summary: In 2018, a disease characterized by splenic hemorrhage and necrosis caused significant mortality among ducks in a farm in Guangxi province, China. A strain of duck reovirus, designated DRV-GL18, was isolated from the dead ducks, and further analysis revealed its genetic features and pathogenicity. This finding suggests the potential for developing a vaccine against this severe duck disease.

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 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.
