The authors of the current study investigated the effects of different concentrations of glutathione peroxidase (GSH-Px) on the quality of frozen-thawed ram semen. Supplementation with 1.6 U/L GSH-Px significantly improved s***m motility, viability, membrane and DNA integrity, acrosome integrity, and mitochondrial activity. GSH-Px also enhanced antioxidant capacity by increasing SOD, CAT, and T-AOC while reducing oxidative stress markers such as MDA and ROS. Proteomic analysis further identified changes in several proteins, suggesting that GSH-Px supplementation improves post-thaw s***m quality by reducing oxidative damage and modulating protein expression.

The authors investigated the effects of faba bean protein isolate (FBPI) and different salt concentrations on the gel and structural properties of pork myofibrillar protein gels. The addition of 1% FBPI improved cooking yield, gel strength, viscosity, and protein surface hydrophobicity compared with the control. Higher salt concentrations, particularly 0.45 M, further enhanced gel strength and cooking yield while producing a more compact and homogeneous protein structure. Overall, the combination of FBPI and appropriate salt concentrations improved the stability and functional properties of pork myofibrillar protein gels, suggesting its potential as a functional ingredient in meat products.

Animal Bioscience 2026; 39(8): 260255. [The study led by Prof. Lingyan Li at Heilongjiang Bayi Agricultural University, Daqing, China]

https://doi.org/10.5713/ab.260255

Authors suggested that rumen-protected glucose (RPG) supplementation strategies in Simmental bulls resulted in increased overall average daily gain (ADG), hot carcass weight, and meat weight. RPG treatments elevated colonic propionate and butyrate concentrations, indicating altered hindgut fermentation patterns and changes in overall colonic bacterial community structure. High-dose RPG supplementation specifically increased intramuscular fat (IMF) content in the longissimus muscle without significantly impairing most other postmortem meat quality traits.

https://doi.org/10.5713/ab.260067

Authors demonstrated that supplementation with 1 mmol/L zinc selenide (ZnSe) nanospheres in boar semen cryopreservation extenders significantly enhanced post-thaw s***m motility, viability, acrosome integrity, and plasma membrane integrity. The optimal 1 mmol/L ZnSe concentration markedly reduced intracellular reactive oxygen species (ROS) and malondialdehyde (MDA) levels while elevating total antioxidant capacity and superoxide dismutase (SOD) and catalase (CAT) activities. These protective effects were attributed to the strong free radical-scavenging activity and antioxidant enzyme modulation provided by the synthesized ZnSe nanospheres during freeze-thaw cycles.

Including dry matter intake (DMI) in CO₂ prediction models significantly improved accuracy and eliminated prediction bias. The DMI-based model estimated the methane-reducing effect of 3-NOP more accurately than conventional CO₂-based methods. This approach provides a more reliable method for evaluating methane-reducing feed additives in dairy cows.

Cold-tolerant Hezuo pigs experienced significantly less lung damage than cold-sensitive Bama pigs during cold exposure. Hezuo pigs maintained oxidative balance and suppressed inflammation and apoptosis, whereas Bama pigs showed severe oxidative stress, inflammation, and tissue damage. Transcriptome analysis identified protective genes in Hezuo pigs and potential biomarkers of cold sensitivity in Bama pigs.

Abstract
Although the demand for poultry products in Indonesia, one of the most significant poultry-producing countries in Southeast Asia, continues to increase, the poultry farming sector continues to face various challenges. This paper provides an overview of the prospects for and challenges faced by the poultry farming sector in Indonesia. Broilers comprise the largest portion of Indonesia’s poultry population, with other commodities contributing less than 10% of the total. During the COVID-19 pandemic, the consumption of chicken meat and eggs increased. The declining national economy led people to consume affordable food for their daily meals, favoring chicken and eggs because their retail prices were four times cheaper than that of beef. In terms of imports to Indonesia, compared with other agricultural commodities, poultry and eggs account for only approximately 1.26% and 0.41%, respectively. Meanwhile, some feed ingredients, such as soybean meal and corn, continue to be imported into Indonesia. According to data from the United States Department of Agriculture, Indonesia imported 4.4 million tons of soybean meal to meet the needs of its poultry industry. In recent years, feed mill companies have rapidly been developing in Indonesia, with an estimated average production of 572,000 metric tons. In terms of scale, poultry farming in Indonesia comprises 60% large-scale farming and 40% small- and medium-scale farming. Many small-scale farms have yet to implement strict biosecurity measures, making climate change a significant challenge for poultry farming in Indonesia. After implementing the ban on antibiotic growth promoters, Indonesia’s poultry farming sector began to stabilize and look for alternative methods to maintain productivity. The use of technology, improved regulations, and the enhancement of farmers’ capacity to manage challenges are key toward sustaining and increasing poultry farming productivity in Indonesia in the future.

Abstract
China’s poultry industry is characterized by large-scale production and rich breeds, presenting both opportunities and challenges. In 2023, the industry produced 10.79 billion broilers, 28.38 million tons of eggs, and 4.88 billion waterfowl. The foundation of a thriving poultry industry lies in the continuous improvement of breeds. For instance, new lines of Lueyang black-boned chickens have been developed using genomic selection breeding, with a focus on improving production performance and unlocking their high-quality genetic potential. Precision nutrition programs enhance the expression of poultry’s genetic potential and improve feed utilization efficiency. The five-dimensional feed evaluation system and the comprehensive National Feed Database provide formulators with accurate nutritional parameters of feed. Additionally, the concept of “nutrition power” and the “five-ring gold standard” enable researchers to analyze poultry’s digestive physiology more effectively. Feeding management plays a crucial role in optimizing genetic potential and the effectiveness of precision nutrition. To further boost production efficiency, smart farming systems have been implemented, incorporating intelligent management of environmental factors, animal parameters, and poultry health tracking. Meanwhile, in order to improve material utilization efficiency across the entire poultry production chain and support the sustainable development of the poultry industry, it is essential to optimize and promote the application of the Poultry-Crop interaction systems. In summary, strengthening fundamental research in poultry, optimizing smart poultry farm platforms, and implementing Poultry-Crop Interacting systems will drive the sustainable development of China’s poultry industry.
