Description
Technical Field

Background
The flos Paulowniae is dried flower of Paulownia of Scrophulariaceae, has wide distribution, is mainly produced in yellow river basin, has large quantity and has wide pharmacological activity. It is rich in organic substances such as protein, amino acids, polysaccharides, glucoside, quercetin, kaempferol, homoeriodictyol, 4,5, 7-trihydroxy-3-methoxyflavone, 5-hydroxy-3, 4, 7-trimethoxybiflavone, luteolin, apigenin, benzaldehyde, vanillin, nonanal, indole, ursolic acid, palmitic acid, 4-methylphenol, 2-methoxyphenol, 3, 4-dimethoxyphenol, 3, 5-dimethoxyphenol, benzyl alcohol, 4-methoxybenzyl alcohol, 3-methoxyphenetol, phenylpropanol, α -terpineol, β -gu-catanol, 1, 4-dimethoxybenzene, daucosterol, verbascoside, 1-acetyl-2- (3 '-hydroxy) octadecanoic acid ester, 2, 4-decadiene, anisene, pinene, romonene, octone, p-methoxyanisole, methyl anisate, dipalmitone, 3' -O-metalacerate, minone, etc., most of the components are fragrant substances, and have the effects of promoting the circulation of qi, inducing resuscitation, relieving exterior syndrome, eliminating dampness, relieving pain, dispersing lung qi and the like, and due to the existence of the organic compounds, the paulownia flower has the effects of resisting oxidation, resisting bacteria, diminishing inflammation, diminishing swelling, growing hair, killing insects, stopping bleeding, relieving cough, relieving asthma, eliminating phlegm, treating tracheitis and the like.
The pig has very obvious preference on sweet food, and experiments prove that in the growth stage (1-28 days) of piglets, the addition of 150mg/kg of additive into the daily ration can achieve larger daily feed intake and can also obtain larger daily gain in the stage. In addition, experiments prove that the additive has an antioxidant function, and can effectively relieve the oxidation degree of the feed along with the prolonging of the storage time of the feed. The essence is the core of the feed additive, and can stimulate the smell of animals to generate a food calling effect. The fragrance composition of the additive is divided into three parts of top fragrance, body fragrance and bottom fragrance according to different volatility. Top notes are the first smells of fragrance to be smelled, which impart diffusion to the additive. Body notes are the smells that can be heard after the top note, and are usually the most important components of additives that impart characteristics to the fragrance. Together with the body notes, the base notes determine the tolerance of the additive to time and temperature, and are important when the feed needs to be expanded and pelleted, and the base notes impart the flavor retention properties of the additive. The proportion and the content of the three components are different, so that different types of odor types can be formed, and the application characteristics of the additive are determined by the different types. Therefore, the traditional additive also has the defects of non-lasting fragrance, over-concentrated fragrance, unstable fragrance and the like.
