“…Water-holding capacity (WHC) is directly related to the esh quality, and it is generally evaluated by steaming loss, centrifugal loss and drip loss [40]. The supplementation of both Eucommia extracts signi cantly promoted the esh WHC by decreasing steaming loss, centrifugal loss and drip loss in this study, and the similar results were also reported in pig [41], chicken [18] and lamb [16]. The improvement of esh WHC mainly resulted from the reduction of oxidative damage, thus promoting the structural integrity of muscle tissue [42].…”

Background: The study investigated the effects of dietary Eucommia ulmoides extracts on growth, esh quality and collagen-related genes expression of grass carp (Ctenopharyngodon idella). Eucommia ulmoides bark extract (EBE) and Eucommia ulmoides leaf extract (ELE) were individually supplemented into basal diet (control) at an inclusion of 4 g/kg, and then the three diets were fed to grass carp (59.7 ± 0.3g) for 60 days.Results: The results indicated that dietary ELE signi cantly increased weight gain (+4.22%), and decreased feed conversion ratio (-0.07) (P<0.05), while EBE did not signi cantly affect the growth performance of grass carp. Compared to the control, dietary ELE increased apparent digestibility coe cient of dry matter, crude protein and intestinal digestive enzyme activity (P<0.05), and the contents of calcium, total collagen, heat-insoluble collagen and free amino acids level (including delicious amino acids) in esh were also increased (P<0.05). In both extracts groups, the esh centrifugal loss, steaming loss, drip loss 24h , protein carbonyl and malondialdehyde were signi cantly lower, and superoxide dismutase and glutathione peroxidase activities were higher than the control (P<0.05). No signi cant differences in the amount of saturated, monounsaturated and polyunsaturated fatty acids in esh were found among the three groups, but DPA, DHA, n-3 polyunsaturated fatty acids and n-3/n-6 ratio in esh were increased by dietary EBE and ELE (P<0.05). In collagen-related genes expression, the ELE supplementation signi cantly promoted the expression of collagen type (COL1A1, COL1A2), proline hydroxylase, lysine oxidasein in muscle, while the expression of matrix metalloproteinase-2 and matrix metalloproteinase-9 was decreased (P<0.05). Conclusion:In conclusion, dietary ELE improved the growth, muscle antioxidant capacity and esh quality of grass carp.

“…As a traditional herb widely used in East Asia, Eucommia ulmoides (EU) has been found many functions including enhancing bones’ strength, antioxidant capacity and immunity and reducing body fattiness (Hussain et al., 2016). In recent years, EU has been used as feed additive in pig (Lee et al., 2009; Zou, Xiang, Wang, Wei, & Peng, 2016), chicken (Hu, Wang, Zhou, & Liu, 2006; Wang, Du, Ye, Tao, & Wang, 2012), lamb (Liu, Li, Zhao, & Deng, 2018; Liu, Zhao, Li, & Deng, 2018) and fish (Sun et al., 2017a; Sun, Xu, Li, Pan, & Leng, 2018; Wang et al., 2018), and the improved growth performance and flesh quality were observed in these studies.…”

Grass carp (Ctenopharyngodon idellus) is an important cultured freshwater fish with the highest production of 5.52 million tons in 2017, accounting for 6.89% of the finfish aquaculture in the world (FAO, 2019). With the increase in intensive aquaculture, the flesh quality of grass carp showed a declining trend, which has become a growing public concern. In the future, the production increase will not be the primary goal in aquaculture, while obtaining high-quality fish products based on a sustainable aquaculture is becoming an important task for the industry (Kobayashi et al., 2015). As a traditional herb widely used in East Asia, Eucommia ulmoides (EU) has been found many functions including enhancing bones' strength, antioxidant capacity and immunity and reducing body fattiness (Hussain et al., 2016). In recent years, EU has been used as feed additive in pig

“…EUL is a dual functional feed, which provides both nutrition and bioactive components such as geniposide acid, aucubin, and chlorogenic acid, which have specific functions in enhancing immunity. Chlorogenic acid can increase antioxidation capacity; for example, by improving SOD and GSH-Px activities and reducing oxidation products, such as MDA, in pigs, chickens, and sheep, thereby improving product quality (4,5,17). In China, EUL is routinely served as food, tea, medicine, and animal feed additives in rural communities (7,18).…”

“…EUL contains more than 50 bioactive substances including chlorogenic acid, geniposide acid, and aucubin, which have antioxidant properties and improve immune function, as well as regulating lipid metabolism (2,3). Supplementation with chlorogenic acid extract from EUL is reported to alleviate the negative effects of heat stress on meat quality and fatty acid profiles in broiler breast meat or mutton, by improving antioxidant status (4,5). Additionally, fatty acid, amino acids, and polysaccharides were identified from EUL (6,7).…”

Eucommia ulmoides leaves (EUL) contain a variety of natural bioactive compounds including chlorogenic acid, geniposide acid, and aucubin. These bioactive chemicals improve immune function and regulate lipid metabolism. The aim of this study was to investigate the effects of EUL on the biochemical properties of milk. Twenty Holstein dairy cows were randomly allocated to two groups fed a control (CTR, diet without EUL, n = 10) or EUL (diet containing 3% EUL, dry matter, n = 10) diet for 55 d. At the end of the experimental period (d 55), milk samples were collected and analyzed to determine their composition. Though levels of milk fat, protein, lactose, and total milk solids were similar between the groups, small molecules, metabolites, lipids, and cytokines differed. Compared with the CTR group, the EUL group had an improved cluster of differentiation (CD)4/CD8 ratio (P < 0.05) and lower interleukin (IL)-8 and IL-6 content (P < 0.05). Metabolomics analysis identified 14 metabolites including 7Z, 10Z, 13Z, 16Z, 19Z-docosapentaenoic acid (FC = 3.129), adrenic acid (FC = 2.830), and eicosapentaenoic acid (FC=1.685) as having significantly increased in the EUL group (P < 0.05) while 11 metabolites, including indole-2-carboxylic acid (FC = 0.636), cholic acid (FC = 0.430), and creatine (FC = 0.784) had significantly decreased (P < 0.05). Based on a constructed metabolome map, linoleic acid metabolism had the highest impact value for EUL. A total of 21 lipid classes and 1,094 lipid species were detected in the milk by lipidomic analysis, among which 40 differed significantly between the CTR and EUL groups. The present findings showed that the EUL altered milk composition. Correlation analysis showed that 7Z, 10Z, 13Z, 16Z, 19Z-docosapentaenoic acid, adrenic acid, and eicosapentaenoic acid levels were negatively correlated with those of the inflammatory factors IL-6 and IL-8 (P < 0.05), indicating that EUL improved milk quality by reducing inflammatory factors and increasing the CD4/CD8 ratio. Overall, our data demonstrate that EUL had positive effects on milk antioxidant parameters, immune indices, and micro-composition metabolism, thereby improving milk quality.
