As an essential component of agricultural branding, the construction of brands for agricultural and livestock products is a crucial lever for transforming traditional production and management methods and adjusting the agricultural industry structure. It plays a key role in implementing the strategy of building a strong nation through brands and promoting the construction of Chinese-style modernization. Practice has shown that Chinese policies for constructing brands of agricultural and livestock products are gradually improving, brand cultivation is gaining momentum, the strength of livestock brands is gradually increasing, and the foundation for brand construction is becoming increasingly solid, to lay a solid foundation for the high-quality construction of agricultural and livestock product brands. Towards Chinese-style modernization, key tasks in building agricultural and livestock product brands include strengthening the main forces in brand construction, enhancing brand influence, reinforcing the processing capacity of agricultural and livestock products, and perfecting the quality traceability system. To accelerate the creation of high-end agricultural and livestock product brands and contribute to the construction of an agricultural powerhouse, it is necessary to actively cultivate and guide to strengthen the main forces in branding, enhance brand influence by omni-channel efforts, expand the industrial chain to improve the processing capacity of agricultural and livestock products, and adhere to standardized development to improve the quality traceability system of agricultural and livestock products.

Flavonoids, as one of the essential active components in alfalfa, possess various beneficial effects such as anti-inflammatory, antibacterial, antiviral, antioxidant, and immune-regulating properties. These flavonoids have the potential to enhance animal growth performance, boost immunity, improve livestock product quality, reduce stress, and prevent and treat diseases, making them widely applicable in the field of animal husbandry. The article introduces the commonly used extraction methods and biological activities of alfalfa flavonoids, reviews the research progress on the application of alfalfa flavonoids in ruminant, poultry, and pig farming, providing a reference for the further development and utilization of alfalfa flavonoids in livestock and poultry production.

The experiment was conducted to study the effect of compound plant essential oils on the production performance and egg quality of laying hens. A total of 13 664 Dawu Jinfeng laying hens with similar body weight and late laying period (362~368 days of age ) were randomly divided into two groups, a control group and a compound plant essential oil group, with four replicates in each group and 1 708 laying hens in each replicate. The laying hens in the control group were fed a basal diet, and the laying hens in the compound plant essential oils group were fed a basal diet supplemented with compound plant essential oils. The trial period was 14 days. The results showed that compared with the control group, the laying rate of laying hens in the compound plant essential oils group was significantly increased (P<0.05), the average egg weight showed an increasing trend (P>0.05), the sand shell egg rate was significantly decreased (P<0.05), and the feed to egg ratio was decreased (P>0.05). Compared with the control group, the egg yolk ratio of the compound plant essential oils group was significantly decreased (P<0.05), and the eggshell intensity had a rising trend. The egg yolk color, hardness, and wetness in the compound plant essential oils group were significantly increased (P<0.05). The study indicates that adding compound plant essential oils to the diet can increase the production performance and egg quality of laying hens. [ABSTRACT FROM AUTHOR]

Yucca belongs to the Yucca genus of the Agave family and is a versatile plant that is edible, medicinal, and ornamental. Yucca extract contains rich saponins, polyphenols and polysaccharides as well as other active ingredients. As a natural, green and safe new feed additive, Yucca extract can fulfill a variety of biological functions in animal production, such as promoting growth, improving reproductive performance, improving feed conversion, regulating the gastrointestinal environment, improving the breeding environment, etc., and has good application prospects in the field of animal husbandry. The article introduces the main active ingredients, chemical structure, biological functions of Yucca extract and its application in animal production, and discusses the possible problems of Yucca extract feed additives, to provide references for further research and application of Yucca extract in animal production.

The aim of the experiment was to investigate the expression of the miR-21-5p gene and its target genes in the mammary tissues of Dehong dairy buffalo. The healthy Dehong dairy buffalo with the same feeding conditions, the same parity, similar age and middle lactation were divided into a high milk fat rate group (group H), a medium milk fat rate group (group M) and a low milk fat rate group (group L). Three dairy buffaloes were selected in each group, and breast tissues were collected after slaughter to extract total RNA. Bioinformatics methods were employed to predict the target genes of miR-21-5p. The expression levels of miR-21-5p and its target genes were quantified by fluorescence quantitative PCR, and correlation analysis was conducted with previously determined milk fat content. The results showed that the possible target genes of miR-21-5p were AGPAT6 and GPAM. The expression level of miR-21-5p in mammary tissue of Dehong daily buffalo in the group L was extremely higher than that in the group M and group H (P<0.01). The results of the correlation analysis showed that the expression level of miR-21-5p was extremely and negatively correlated with the target gene AGPAT6 (P<0.01), and significantly and negatively correlated with the expression level of the target gene GPAM (P<0.05). In the mammary tissue of Dehong dairy buffalo, the expression level of miR-21-5p was significantly and negatively correlated with the milk fat protein interaction network showed that the interaction between AGPAT6 and GPAM was the strongest. The results indicate that miR-21-5p may influence milk fat 31460649) synthesis by negatively regulating the expression of the target genes AGPAT6 and GPAM, and consequently influencing the milk fat percentage.

The experiment was to study the effect of complex plant essential oil on growth performance and immune indexes of carp. A total of 360 healthy carp with weight (182.61±3.01) g and body length (21.90±0.60) cm were randomly divided into four groups, with three replicates in each group and 30 carp in each replicate. Carp in control group, test group 1, test group 2 and test group 3 were fed with compound diets containing 0, 100, 200 and 400 mg/kg complex plant essential oil, respectively. The pre-test lasted for 14 d, and the formal test lasted for 45 d. The results showed that compared with control group, the final weight, WGR and SGR of carp in all groups were significantly increased (P<0.05), and the feed coefficient was significantly decreased (P<0.05), and WGR and SGR of carp in 400 mg/kg group were increased the most. The content of TP and ALB in serum of carp in test group 2 were significantly higher than those in control group (P<0.05), and the activity of T-SOD was significantly higher than that in control group (P<0.05). The activity of AKP and AST in serum of carp in test group 3 were significantly higher than those in control group (P<0.05). The study indicates that adding complex plant essential oil to carp feed can improve growth performance and enhance immune function, and the suitable amount is 200 mg/kg. [ABSTRACT FROM AUTHOR]
