Functional pellet feed for preventing recessive mastitis of dairy cows in pregnancy and lactation period and quality detection method of functional pellet feed

The invention discloses a functional pellet feed for preventing recessive mastitis of dairy cows in the pregnancy and lactation period and a quality detection method of the functional pellet feed. A functional natural plant composition for feed is prepared from folium cortex eucommiae, radix paeoniae alba, semen cuscutae, herba taraxaci, folium perillae, semen lablab album and radix glycyrrhizae. The functional pellet feed is prepared from the natural plant composition for the feed and basic feed soybean meal, corn, wheat bran, yeast powder and the like. The detection method comprises the steps of multi-component content determination and fingerprint spectrum determination, a large number of experiments are provided for screening out the optimal chromatographic conditions, and the established detection method has the advantages of being convenient to operate, reliable, good in reproducibility and the like. The quality detection method of the natural plant composition for feeding is an important means for ensu
