This paper employed the SWOT analysis method to systematically investigate the internal and external environment for the high-quality development of the dairy industry in Dongying City,Shandong Province. The analysis first identified internal strengths,including high milk yield per cow,a high degree of scale in farming,good quality of milk sources,and strong policy support. It also points out existing weaknesses,such as weak local processing capacity,insufficient market competitiveness,and a fragile interest linkage between farmers and dairy enterprises. Regarding the external environment,the study identified opportunities from growing consumption potential and policy support,as well as threats from intensified resource and environmental constraints,impact from imported dairy products,and a sluggish market. Based on this analysis,four strategic combinations—SO,WO,ST,and WT—were constructed,with the SO strategy,leveraging strengths and seizing opportunities to promote integrated development of the entire dairy industry chain,recommended. Finally,specific countermeasures and suggestions were proposed to promote the high-quality development of Dongying's dairy industry,focusing on areas such as enhancing breeding capacity,improving quality and efficiency,extending the industry chain,promoting green and sustainable development,and strengthening interest linkage mechanisms.

With the accelerating development of globalization and informatization,consumers are increasingly focusing on enterprises' corporate social responsibility （CSR）performance in addition to product quality and price when making brand choices. This study explored the impact of CSR on consumer brand choice behavior in the dairy industry. Employing a questionnaire survey method and various statistical analysis techniques,including descriptive statistics,reliability analysis,factor analysis,and structural equation modeling （SEM）—the research conducts an in-depth analysis of the application of CSR in dairy enterprises and its influence on consumer behavior. A hypothetical model is designed to provide empirical support for revealing the mechanism of CSR in consumer brand selection.The results indicated that different dimensions of CSR exert a significant impact on brand trust and brand advocacy,with environmental protection responsibility and social support responsibility demonstrating particularly notable effects on brand behavioral intentions. To be specific,consumers' perceived CSR has a significant positive impact on brand support： when consumers perceive a company actively fulfilling its social responsibilities,they tend to support the brand more.Fulfilling social responsibilities helps companies boost brand reputation,which in turn strengthens consumers' admiration for the brand.Notably,if consumers believe a company's CSR efforts are driven by genuine altruism,this perception will further amplify the positive effect of CSR on brand admiration. These findings offer important theoretical implications for dairy enterprises in formulating CSR strategies.

This study focused on the application of appeasing pheromones during the weaning process of calves. It elaborated on the current status of weaning stress in calves,including the causes of weaning stress and its adverse effects on calf physiology and behavior,such as the release of stress hormones like cortisol,which lead to growth retardation and immune suppression. The mechanism of action of appeasing pheromones was detailed,explaining how they are recognized by the vomeronasal organ in the nasal cavity,transmit signals to the hypothalamus,and influence animal emotions and hormone secretion,thereby alleviating weaning stress in calves. Through multiple practical research cases,the application effects of appeasing pheromones in calf weaning were thoroughly analyzed,including the reduction of stress indicators,improvement in daily weight gain,and decreased disease incidence. The optimal application methods and future development prospects of appeasing pheromones were also discussed,providing comprehensive and scientific references for weaning stress management in calves and contributing to the healthy development of the beef and dairy cattle farming industries.

Aflatoxins（AF）are secondary metabolites produced by fungi such as Aspergillus flavus and Aspergillus parasiticus. Under favorable conditions,they can contaminate food and animal feed,posing health risks to both humans and animals. Dairy cows exposed to aflatoxin B₁（AFB₁）excrete its metabolite aflatoxin M₁（AFM₁）into milk,compromising milk safety. This review systematically summarized the effects of AF on dairy cow production performance,rumen fermentation,and reproductive function,and outlines recent advances in the physical,chemical,and biological methods for aflatoxin degradation. The aim is to provide a theoretical basis for preventing and controlling the risks of AF in dairy production.

Indonesia is a major agricultural country,but its dairy industry remains underdeveloped,primarily relying on smallholder farming （average herd size below 5 cows）,with over 70% of raw milk supplied by dairy cooperatives and a low proportion of modern dairy farms. In 2023,the national dairy cattle inventory stood at 258 800 heads,with milk production reaching 672 000 tons—only 2.42 kg per capita annually,far below international standards. Consequently,Indonesia heavily depends on dairy imports,which have shown an overall upward trend over the past decade,while exports remain low （25 000~52 000 tons）,resulting in a significant trade deficit. Milk powder is the primary imported category,accounting for 27.33% （261 500 tons） in 2023,New Zealand,the U.S.,Australia,and three other countries dominating the stable trade structure. Dairy trade between Indonesia and China has been limited,with infant formula being the main import from China in recent years. Considering trade policies,Indonesia’s Free Nutritious Meal Program,and dairy price competitiveness,China hold geographical and cost advantages in dairy exporting,indicating notable cooperation potential.

In the development of animal husbandry, cold stress during winter is a critical issue constraining the healthy production of dairy cows.Cold stress leads to reduced feed intake, as well as significant declines in milk yield, reproductive performance, and overall health status.This paper analyzed the impacts of cold stress from dimensions such as milk production, behavior, and reproductive performance, and proposed comprehensive mitigation measures, including physical insulation （such as optimizing barn structure and increasing bedding）, nutritional regulation （such as supplementing high-energy feed）, and environmental control.These strategies provided technical references for ensuring the healthy and efficient production of dairy cows during winter.

[Objective] In response to the high incidence of dairy cow endometritis in hot and humid summer environments and the challenge of antibiotic resistance in traditional treatments,this study systematically evaluated the application effect of cloprostenol sodium combined with anionic salt diet in the prevention and control of endometritis,aiming to provide scientific strategies for dairy farms. [Method] From June to August 202,160 Holstein cows in a large-scale dairy farm of Shandong were randomly divided into four groups: conventional treatment group （antibiotics + uterine lavage）,cloprostenol sodium treatment group （conventional treatment + cloprostenol sodium）,cloprostenol sodium + nutrition group （conventional treatment + cloprostenol sodium + anionic salt diet）,and control group. The differences in endometritis incidence,treatment efficacy,reproductive performance,and blood biochemical indicators were compared and analyzed. [Result] The combination of cloprostenol sodium and anionic salt diet reduced the incidence of endometritis by 27.3%,increased the cure rate to 95.0%,shortened uterine involution time by 20.7%,advanced the first estrus time by 23.7%,improved conception rate by 14.7 percentage points,and significantly enhanced antioxidant capacity and calcium metabolism. [Conclusion] This comprehensive approach demonstrated significant economic benefits （net profit + 230 RMB per cow） and provided a safe and efficient alternative for the prevention and control of dairy cow endometritis in summer.

[Objective] Satisfaction research is widely applied in non-FMCG industries,particularly in retail,finance,and aviation services,yet it remains largely untapped in the FMCG sector.This study constructs a satisfaction index system for the liquid dairy product industry,aiming to provide insights and reference strategies for enhancing product satisfaction and refining consumer experiences. [Method] An online questionnaire survey was conducted using random and targeted sampling, along with sample augmentation method to collect data. Regression models and Shapley Value analysis are employed to identify important consumer experience touchpoints and indicators. [Result] A consumer satisfaction indicator system is developed,encompassing 4 secondary and 33 tertiary indicators,while considering market share in the assessment of brand/category importance. [Conclusion] The satisfaction scores measured by the indicator system align with market sales data.The analysis of MOTs driving overall satisfaction suggests that consumers’ current demands for liquid dairy products are primarily focused on the physical level.Therefore,Dairy company should prioritize attention to the purchase and usage experience, and then gradually meet the needs for emotional connection.

[Objective] To enrich forage resources for dairy cows and explore the effects of feeding ensiled sweet sorghum to dairy cows. [Method] The effects of ensiled sweet sorghum on dairy cows were analyzed in terms of milk yield performance and milk quality. [Result] Under the same dry matter intake conditions, the average cumulative milk yield and daily milk yield per cow in the experimental group were 1 049.99 kg and 17.50 kg, respectively, representing increases of 65.79 kg and 1.10 kg compared to the control group. Notably, the average daily cumulative milk yields at 45 d and 60 d showed significant differences （P<0.05） compared to the control group at the same periods. No significant differences were observed in milk fat, milk protein, non-fat solids content, or relative density. [Conclusion] During the trial period, feeding ensiled sweet sorghum contributed to an increase in milk yield, with no significant short-term impact on milk quality. However, long-term effects require further study. Ensiled sweet sorghum, as a high-quality roughage, is suitable for promotion in dairy farming.

Summer cow metritis is a major reproductive disorder in dairy farming,with its incidence and severity significantly increasing under high-temperature and high-humidity conditions. The disease is primarily caused by pathogenic microorganisms such as Fusobacterium spp.,Bacteroides spp.,Trueperella pyogenes and Escherichia coli,which proliferate more aggressively and invade the uterus under heat stress. The pathogenesis involves three key aspects：（1）exogenous infection,where pathogens directly invade through the open cervix during parturition;（2）endogenous infection,where metabolic disorders（e.g.,ketosis,ruminal acidosis）in the peripartum period compromise the intestinal barrier,allowing pathogens to migrate to the uterus via blood circulation;and（3）hormonal imbalance,where a sharp decline in postpartum estrogen levels suppresses immune function.Clinical manifestations include endometrial inflammation and purulent lochia discharge. The disease can be categorized into clinical endometritis （CE）and subclinical endometritis （SE）. While SE is asymptomatic,it poses greater harm,significantly reducing conception rates—some studies report a decline of over 50%. Epidemiological studies indicate that first-calving cows have a higher incidence than multiparous cows,with retained placenta,stillbirth,and dystocia being major contributing factors.In regions with hot and humid summers—such as Tianjin,southern Shaanxi,inland Shandong and Henan—heat stress reduces feed intak,weakens immunity,and promotes pathogen proliferation,leading to a higher incidence of metritis compared to other seasons. Prevention and control strategies should focus on environmental management,nutritional optimization and biosecurity measures.
