Summary: There are concerns about using imported soybean meal to feed dairy cows in Europe, but wheat DDGS from European bioethanol production can be a suitable alternative. The inclusion level of European wheat DDGS in high-yielding dairy cow diets is crucial, with the results showing that an inclusion level of at least 22.5% is optimal. The study demonstrates that European wheat DDGS can effectively replace soybean meal in dairy cow diets at high inclusion levels.

Summary: To meet the sustainable development of the swine feed industry, new feed resources and processing technologies need to be developed. Co-fermentation of distillers dried grains with solubles (DDGS) and lignocellulosic feedstocks can produce easily digestible and highly nutritious swine feed. This approach can guide cleaner swine farming, alleviate the demand for high-value swine feed, and support the growing pork market.

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 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.
