Summary: This study investigated the potential use of a phage cocktail in combination with probiotics as an alternative to antibiotic growth promoters (AGPs) in poultry farming. The results showed that the combination of phage and probiotics improved growth performance in chickens and had a positive impact on the diversity and composition of gut microbiota. This study suggests that using a phage cocktail in combination with probiotics could be a promising alternative to AGPs for poultry production.

Summary: A survey conducted in Croatia over a period of nine years investigated the prevalence and number of Shiga toxin-producing Escherichia coli (STEC) in animal feed. The study found that poultry feed contained STEC strains, with 27 strains confirmed as STEC, potentially serving as a source of human illnesses. Further research is needed to evaluate the risks posed by contaminated feed, poultry, and the environment.

Summary: With the prohibition of antibiotics in poultry feed becoming widespread, the use of natural feed additives and alternatives is necessary to stimulate the immune systems of broiler chickens. This review explores the effectiveness of plant-derived additives in improving the avian immune system and broiler health. However, excessive use of additives may reduce immunocompetence, making it important to determine tolerance levels and optimal doses.

Summary: This study found marked differences in antibiotic resistance between countries, farms, and within farms in Belgium and the Netherlands. ESBL-E. coli were more prevalent in Belgian samples, while CiproR-E. coli were highly prevalent in broilers of both countries. Multidrug resistance was frequently observed in samples from both countries, with a higher prevalence of ESBL production in combination with ciprofloxacin resistance in samples from Belgium.

Summary: Colibacillosis in chickens can lead to death, weight loss, and economic losses. Antibiotic therapy is currently the main treatment method, but the rise of antibiotic resistance highlights the need for alternative treatments that align with the One Health concept. Phage therapy meets these requirements.

Summary: This study evaluated the effects of garlic and dill as well as atorvastatin on lipogenesis in broiler chickens. The results showed that all three supplements improved weight gain, feed conversion ratio, and villi dimensions. In addition, atorvastatin and the supplements increased nitric oxide levels while decreasing malondialdehyde, triacylglycerol, and LDL levels and improving cardiac function. The supplements also regulated oxidative stress response and expression of lipogenic enzymes.

Summary: Sheep exhibit phenotypic diversity and adaptability to different climates. This study investigates the associations between copy number variations (CNVs) and climate-driven adaptive evolution in sheep populations. Through genomic analysis, the researchers identified specific CNVs that are significantly associated with climatic variables, including genes related to heat stress, cold climate adaptation, coat and wool traits, DNA repair, metabolism, fertility, growth, and immune response in sheep. The findings suggest that CNVs can serve as valuable genomic markers for selecting sheep adapted to specific climatic conditions.

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 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.
