“…The antibody titer against infectious bursal disease virus in broilers with treatment of Echinacea purpurea extract (0.1–1 g/kg) was significantly higher than that in control group [ 28 ]. Adding 0.5% Echinacea into diet had an enhancing effect on response of influenza vaccine [ 29 ]. Swine fever and swine foot-and-mouth disease are acute and infectious diseases which happened worldwide and brought huge losses to mankind [ 30 ].…”

Resveratrol, a polyphenolic plant antitoxin, has a wide range of pharmacological activities. In this study, we systematically evaluated the effects of resveratrol dry suspension (RDS) on immune function in piglets that were treated with different doses of RDS for 2 weeks. The results showed that the RDS has significant effects on the development, maturation, proliferation, and transformation of T lymphocytes. RDS could regulate humoral immune responses by upregulating the release of IFN-γ and downregulating the release of TNF-α. After piglets were vaccinated against classical swine fever virus and foot-and-mouth disease virus, the antibody titers were significantly increased. RDS treatment showed an excellent resistance to enhance T-SOD activity. Values of blood routine and blood biochemistry showed no toxicity. These results suggested that RDS could be considered as an adjuvant to enhance immune responses to vaccines, as well as dietary additives for animals to enhance humoral and cellular immunity.

The aim of the study was to determine the effect of dietary addition of dried purple coneflower (Echinacea purpurea (L.) Moench) on selected blood parameters of chicks and hens of the native ‘Greenleg Partridge’ breed (Z-11), maintained on a certified poultry farm according to organic farming principles. Birds were divided into two groups according to diet: organic layer diet (group 1), and the same diet supplemented with certified purple coneflower from 20 weeks of age at 10 g/kg feed (group 2). Layers were fed the certified layer diet (17% protein and 11.1 MJ ME/kg diet) following organic farming principles. Experimental incubations were performed at 34 wks of age. Blood was collected from laying hens at 34 wks and from newly hatched chicks at one day of age to determine selected blood parameters. The organically raised ‘Greenleg Partridge’ hens and chicks responded to the purple coneflower supplement by changes in blood picture, which are important indicators of avian health and condition. As in Z-11 chicks, purple coneflower supplemented to the layer diet reduced the H:L ratio and induced a tendency for higher level of the immunoglobulin complex and IgG in blood, which shows their better living comfort and higher immunity. Dietary purple coneflower was observed to have no effect on the level of hematocrit, erythrocytes and leukocytes. High individual variation occurred for the immunoglobulin complex and IgG in the organically raised ‘Greenleg Partridge’ hens.

Context: Plants of the genus Echinacea (Asteraceae) are among the most popular herbal supplements on the market today. Recent studies indicate there are potential new applications and emerging markets for this natural health product (NHP).Objective: This review aims to synthesize recent developments in Echinacea biotechnology and to identify promising applications for these advances in the industry.Methods: A comprehensive survey of peer-reviewed publications was carried out, focusing on Echinacea biotechnology and impacts on phytochemistry. This article primarily covers research findings since 2007 and builds on earlier reviews on the biotechnology of Echinacea.Results: Bioreactors, genetic engineering and controlled biotic or abiotic elicitation have the potential to significantly improve the yield, consistency and overall quality of Echinacea products. Using these technologies, a variety of new applications for Echinacea can be realized, such as the use of seed oil and antimicrobial and immune boosting feed additives for livestock.Conclusions: New applications can take advantage of the well-established popularity of Echinacea as a NHP. Echinacea presents a myriad of potential health benefits, including anti-inflammatory, anxiolytic and antibiotic activities that have yet to be fully translated into new applications. The distinct chemistry and bioactivity of different Echinacea species and organs, moreover, can lead to interesting and diverse commercial opportunities.
