Adjuvant Effects of Platycodin D on Immune Responses to Infectious Bronchitis Vaccine in Chickens.

Adjuvants are common vaccine components. Novel adjuvants may improve the protective immunity conferred by vaccines against poultry diseases. Here, a less-hemolytic saponin, platycodin D (PD), isolated from the root of was investigated as a potential alternative adjuvant.

Effect of the flavonoid baicalein as a feed additive on the growth performance, immunity, and antioxidant capacity of broiler chickens.

Baicalein, the main flavonoid extracted from the root of Scutellaria baicalensis Georgi, has been demonstrated to exert multiple pharmacological effects, and thus could be utilized as a potential feed additive in broiler chickens. This study evaluated the effects of broiler chicken diet supplementation with baicalein on growth performance, immunity, and antioxidant activity at levels of 100 and 200 mg/kg. No significant effect on average daily feed intake (P > 0.

[SNP marker and allele-specific diagnostic PCR for authenticating herbs of Perilla].

Aim: To authenticate all the varieties of Perilla (single-species genus), to analyze sequences of rDNA ITS regions and single nucleotide polymorphism (SNP) within them and based on these, to design allele-specific diagnostic PCR primers.

Methods: The rDNA ITS regions of the perilla varieties were sequenced and analyzed by Clustal X 1.8, MEGA 3.
