Summary: This study evaluated the effects of vitamin D supplementation on the reproductive performance, egg quality, serum hormone levels, and antioxidant capacity of breeder geese during the laying period. The results showed that a combination of 400 IU/kg vitamin D-3 and 50 μg/kg 25-OH-D-3 had the best feed conversion ratio and egg laying rate. Vitamin D-3 supplementation improved eggshell quality, serum hormone levels, and antioxidant capacity, while 25-OH-D-3 supplementation improved intestinal morphology and serum antioxidant capacity.

Summary: The study evaluated the effects of organic micromineral zinc and manganese, along with 25-hydroxycholecalciferol, on late-phase laying hens. Results showed that organic manganese supplementation led to lower feed intake, while supplementation with Zn-Met, Mn-Met, or 25-hydroxycholecalciferol increased eggshell thickness. Additionally, yolk lipid stability was only affected by storage time rather than supplementation, and there was minimal impact on bone quality.

Summary: In this study, the impact of resistant starch (RS) on meat duck intestine and its resident microbiota was investigated. The results showed that dietary RS improved intestinal morphology and barrier function in meat ducks, as evidenced by enhanced expression of tight junction proteins and Mucin-2 gene. RS administration also led to changes in the gut microbiome and metabolome, with increased proportions of Firmicutes and butyrate-producing bacteria, as well as alterations in amino acid and lipid metabolism. These findings provide valuable insights into the mechanism by which RS improves the gut system of ducks.

Summary: This study conducted computational case studies on different mask products applicable to low-, medium-, and high-risk scenarios. The results showed that reusable cotton masks and disposable medical masks suitable for low-risk settings have a lower carbon footprint, becoming more environmentally friendly after a certain number of washes. Disposable surgical masks and KN95 respirators have higher carbon footprints, while disposable medical masks and disposable surgical masks are identified as alternatives with better environmental performance in medium- and high-risk environments. The results provide scientific guidance for manufacturers and consumers on the production and use of protective masks.

Summary: This study investigated the effects of 25-hydroxyvitamin D (25OHD) on egg production, egg quality, immune response, and intestinal health of laying hens challenged with Escherichia coli lipopolysaccharide (LPS). The results showed that supplementing 80 mg/kg of 25OHD in diets can improve egg laying rate and feed efficiency, decrease broken egg rate, and enhance intestinal barrier function and antioxidant capacity. Additionally, it can also decrease proinflammatory cytokines levels in laying hens. Therefore, the addition of 25OHD in diets may enhance laying performance and egg quality in LPS-challenged hens.

Summary: This study suggests that silibinin, a component of milk thistle, can reduce inflammatory responses and increase milk production in lactating sows. It exerts its effects by regulating the mTOR/NF-κB signaling pathway in porcine mammary epithelial cells. Silibinin may be a potential dietary strategy to alleviate inflammation in lactating sows.

Summary: To understand the aging mechanism of down fiber under daily washing and drying conditions, the effects of different treatments on fluffiness, whiteness, microscopic morphology, crystallinity, and molecular structure were observed. Results showed that weak acid or alkali washing conditions and low temperature drying only slightly affected the properties of down fiber. Mechanical agitation had a positive impact on fluffiness and whiteness. However, strong alkali washing and high temperature drying caused significant damage to the fiber. Regardless of the conditions, prolonged mechanical agitation led to performance degradation. Down fiber is best suited for weak acid or alkali washing and low temperature drying with minimal mechanical agitation.

Summary: The mechanism by which acute endoplasmic reticulum (ER) stress suppresses hepatic gluconeogenesis is unclear. This study found that MAPK phosphatase 3 (MKP-3) plays a positive regulatory role in this process. Acute ER stress inhibits hepatic gluconeogenesis by degrading MKP-3. Therefore, MKP-3 may be a therapeutic target for drug-induced liver injury (DILI)-related hypoglycemia.

Summary: FGF21, a hormone released in the liver, has been identified as an important endocrine signal for dietary protein intake. This study investigated the role of FGF21 and hypothalamic changes in controlling estrous cyclicity by dietary protein intake. The research found that severe dietary protein restriction resulted in the cessation of estrous cyclicity and ovarian follicle development, and hepatic FGF21 and hypothalamic Kiss-1 were partially required for this process.

Summary: This paper reports a bifunctional microwave metasurface with an asymmetric bidirectional transmission phase that can be controlled. The metasurface is composed of bilayered double-arrow-shaped structures sandwiching a subwavelength metal grating. The metasurface breaks the symmetry and realizes different functions for opposite propagation directions, such as deflection and focusing, orbital angular momentum (OAM) mode generation, and holographic imaging. The experimental results suggest that the proposed metasurface can be further exploited for various applications.

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 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.
