Summary: The poultry feed industry is active in many countries and has gained market acceptance. Pelleted feed is the final product for poultry, which is convenient for consumption. However, the high cost of imported poultry pellets poses a challenge for many feed industries. Therefore, it is crucial to be able to produce poultry feed at a lower cost while meeting the desired quantity and quality of pelleted feeds for the viability of the enterprise.

Summary: Completing the loop of the Miscanthus value chain requires returning waste to the production cycle for sustainable use and a zero-waste approach. Utilizing Miscanthus feedstock to produce biochar and biogas, and incorporating biochar into phytoremediation and crop production cycles can improve soil characteristics and biodiversity.

Summary: Severe environmental and ecological problems have occurred in Dongting Lake due to unharvested miscanthus biomass. Pyrolyzing the biomass to produce biochar is a promising solution. This study investigated two biomass biomodification techniques, fungal decomposition and bacterial digestion, as well as a biochar Fe-modification technique, to improve the sorption efficiency of biochar. The results showed that both biomass modification techniques increased the Cd sorption capacity of biochar, and Fe modification further enhanced the sorption capacity.

Summary: Due to the growing demand for food, the use of co-products from the food and biofuel industry in livestock feed is expected to increase. However, these co-products, which are fiber-rich, can negatively affect pellet manufacturing, leading to reduced pellet quality and increased energy costs. This study aimed to investigate the impact of including fibrous co-products in feed on their thermomechanical properties and subsequent effects on pellet manufacturing.

Summary: This study examined the impact of extruded feed physical pellet quality (PPQ) on the physiological response of spotted seabass. Two batches of pellets with contrasting PPQ, created by different water levels during the extrusion process, were fed to the fish. The study found that PPQ influenced stomach water fluxes, digesta evacuation rate, feed conversion ratio, protein efficiency ratio, hepatosomatic index, and postprandial plasma glucose level in the fish.

Summary: The study demonstrates that Miscanthus biochar can improve the soil environment and enhance soybean growth. The addition of biochar increases soil organic matter and available phosphate, and alters the structure of microbial communities. These changes result in increased root dry weight, nodule number, and seed yield in soybeans.

Summary: Miscanthus is a commercial lignocellulosic biomass crop known for high biomass productivity, resilience, and photosynthetic capacity at low temperatures, making it suitable for temperate marginal land. Different phenotypic responses were observed among Miscanthus genotypes from different species under drought stress, while biomass yield was higher in flooded conditions. Despite variations in differentially expressed genes, shared molecular processes were regulated during drought stress across Miscanthus species.

Summary: A major application of residual biomass from forestry and agriculture is to compact it into biomass pellets. This study investigated the relationship between the tumbler durability Dt (industry standard) and the single pellet durability Dsp. The research found that Dsp has a stronger correlation with Dt when the single pellet durability is high, and a linear equation can accurately convert Dsp to Dt when the moisture content of wood pellets is below 10% w.b.

Summary: Pellet durability index (PDI) is a widely accepted measure for pellet quality, but in some cases, a better discriminator is needed. The hypothesis that the average linear dimensions of animal feed pellets would vary based on formulation and pelleting process variables was tested. It was found that PDI obtained through aggressive durability testing is a better discriminator of quality among pelleted products due to its greater resolution compared to pellet length.

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 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.
