“…(2013) , who demonstrated that dietary supplementation with A. vera polysaccharide increased IFN-γ production in serum of weaned piglets. Furthermore, some others had also reported that dandelion root extract (major bioactive components are polysaccharide and flavone) and Astragalus polysaccharide supplementation in the diet increased IFN-γ level in serum of pigs ( Yuan et al., 2006 , Zhao et al., 2019 ). Therefore, these results implies that dietary supplementation with certain kinds of Chinese herbs could improve the immune function of weaned pigs.…”

Lycium barbarum polysaccharides ( LBP ) are considered to be the major bioactive components of L. barbarum and have been widely used as a well-known traditional Chinese medicine and functional food because of their various biological activities. However, no published research has investigated the use of LBP as a feed additive in broilers. The objective of this study was to evaluate the effects of dietary LBP supplementation on the growth performance, digestive enzyme activities, antioxidant status, and immunity of broiler chickens. A total of 256 one-day-old Arbor Acres male broiler chicks were randomly allotted into 4 groups, with 8 replicates of 8 birds each, and were fed a corn–soybean meal–type basal diet supplemented without (control group) or with 1,000, 2,000, or 4,000 mg/kg LBP for 6 wk. The results showed that compared with the control diet, a significant increase in ADG ( P < 0.05) during the grower and overall periods was observed in chickens fed the basal diet supplemented with 2,000 mg/kg LBP, whereas supplementation with 1,000 or 2,000 mg/kg LBP decreased feed-to-gain ratio ( P < 0.05) during the starter period. The inclusion of LBP in the broiler diets increased overall amylase, lipase, and protease activities ( P < 0.05). Supplementation with increasing levels of dietary LBP increased the activities of superoxide dismutase and glutathione peroxidase but decreased malondialdehyde content in the serum and liver ( P < 0.05). Broilers fed with LBP-containing diets exhibited higher serum IgG and IgA concentrations ( P < 0.05) than the broilers fed with the control diet. Serum tumor necrosis factor α and IL-4 concentrations were significantly elevated in the group fed 2,000 mg/kg LBP compared with the control group ( P < 0.05). Broilers fed diets supplemented with LBP showed linear ( P < 0.05) and quadratic ( P < 0.05) increases in serum IL-6 and interferon gamma concentrations. The results indicated that dietary LBP supplementation can improve growth performance, digestive enzyme activities, antioxidant capacity, and immune function of broilers. In conclusion, LBP may be used as a promising feed additive for broilers, and a supplementation level of 2,000 mg/kg LBP in the broiler diet is recommended.

“…Thus, preparations exerting both antioxidant and anticoagulant activities based on safe natural substances are continuously sought after for their potentially wide range of health benefits in the prevention and treatment of cardiovascular disorders [1][2][3][4][5][6][7].Nowadays, the dandelion (Taraxacum officinale) herb and root are used as a component of food products, dietary supplements and pharmacological preparations for various ailments (mainly liver, gallbladder and kidney disorders) [8,9]. This is due to a wide range of biological activities, including antihyperglycemic, antioxidant and anti-inflammatory actions demonstrated by dandelion fractions and their constituents, with no reported adverse effects, together with a well-understood chemical composition and a widespread occurrence of the plant throughout the world [10,11]. Aqueous-organic extracts from the dandelion herb were found to exert an anti-inflammatory action [12], mainly due to decreasing the expression of proinflammatory cytokines by inhibiting the nuclear factor (NF)-κB [13], tumor necrosis factor (TNF)-α and interleukin (IL)-1β [14], as well as reducing the expression and production of inducible nitric oxide synthase/nitric oxide (iNOS/NO) and cyclooxygenase (COX)-2/prostaglandin E2 [15].Plant polyphenols have the ability to protect dietary lipids, proteins and vitamins from oxidation.…”

Alcoholic leaf and petal fractions of Taraxacum officinale (dandelion) were previously demonstrated to exert in vitro antioxidant and antithrombotic activities in blood plasma and platelets. Eight-week-old male Wistar rats (n = 6) were supplemented for four weeks with dandelion fractions (694 mg/kg of diet = 11.9 ± 0.6 mg daily). Dandelion leaf and petal fractions, which delivered daily 4.10 ± 0.05 and 1.41 ± 0.07 mg l-chicoric acid, respectively, were shown to exert antioxidative actions, measured as decreased levels of thiobarbituric acid-reactive substances (TBARS) in the spleen (≈0.8-fold, leaves and petals), brain (0.53-fold, leaves) and thoracic arteries (0.59-fold, petals). Moreover, petal fraction increased thiols in the blood plasma (1.58-fold), while leaf fraction decreased protein carbonylation levels (0.59-fold). Additionally, dandelion leaf fractions modified the lipid profile: decreased triglyceride (0.44-fold), total cholesterol (0.73-fold), lipoprotein combine index (0.32-fold) and the atherogenic index of plasma (0.62-fold). Dandelion fractions showed a beneficial decrease effect in the participation of cyclooxygenase products in the noradrenaline-induced vascular contractions of thoracic arteries. Meanwhile, only the dandelion leaf fraction augmented acetylcholine-induced vasodilation and upregulated K ATP channels. The heart rate and blood pressure were not modified. Dandelion leaf and petal phenolic fractions, enriched with l-chicoric acid, are promising plant materials that may exert in vivo beneficial antioxidant effects.Antioxidants 2020, 9, 131 2 of 13 as thrombosis and atherosclerosis.

“…Herb complex extract also has been widely used as a substitute for antibiotics in feed additives (Yan, Meng, & Kim, 2012;Zhou, Zhang, & Kim, 2013). It also confirmed that the addition of herbal extracts to diets could improve the growth performance and immune function of weaned piglets (Zhao, Zhang, Zhou, Dong, & Zhang, 2019). Multi-enzyme complex also can promote the digestion and absorption of nutrients and, effectively inhibit the growth of pathogenic bacteria in the intestinal tract of livestock and poultry (Mohammadi Gheisar, Hosseindoust, & Kim, 2016;Zhang, Yang, Wang, Yang, & Zhou, 2014).…”

This study was conducted to investigate the effects of composited functional bioactive substances on the growth performance and immune function of growth retardation (GR) pigs. Twenty-four 42day-old GR pigs were fed with basal diet containing 0 or 0.5% composited functional bioactive substances package (FP) for 21 days. The results showed that dietary supplementation with FP decreased feed:gain ratio, increased the relative and absolute weight of the liver (P < 0.05). Supplementation with FP decreased serum alkaline phosphatase and malondialdehyde, but increased aspartic acid, cysteine, arginine, proline and taurine concentrations, as well as serum superoxide dismutase and catalase activities (p < 0.05). FP treatment increased all determined cytokines (IL-1β, IL-4, IL-6, IL-8, IL-10, IL-12, GM-CSF, IFN-γ, TGF-β1, TNF-α) concentrations in serum compared with the control treatment (p < 0.05). These findings indicate that functional bioactive substances can improve feed conversion rate, serum anti-oxidant capacity and immunity and can be as effective growth promoter in the GR piglets.
