The invention discloses a
feed additive with a release effect and capable of treating sow metritis. The
feed additive is prepared from the following components: soybean pulp, corn, grape
skin pomace,
astilbe chinensis, herba leonuri, radix angelicae sinensis, cortex ilicis rotundae, ossa draconis, fructus
ligustri lucidi, rhizoma atractylodis macrocephalae,
herb of adnate elder, herba salviae chinensis, herba taraxaci, rhizoma zingiberis recens, fructus crataegi,
pericarpium citri reticulatae, fructus jujubae, silkworm chrysalis,
sodium alginate,
chitosan,
starch,
magnesium stearate and
sucrose ester. The preparation method comprises the following steps: material preparation, extraction of effective components of
traditional Chinese medicine bulk drug, pelleting, tabletting and pelleting. The
feed additive disclosed by the invention is capable of resisting
bacteria, diminishing
inflammation, activating
blood circulation, removing
blood stasis, draining
toxin, expelling pus, invigorating
spleen-
stomach and replenishing qi, and is capable of effectively treating the sow metritis; durable and slow in-vivo
drug release can be realized, the
blood concentration is stable, and the fluctuation is small, so that the
dosing frequency is reduced, the concentration of effective
drug components in blood is controlled so as to maintain the pharmacological function, the peak times of
drug release are reduced, and certain protection is carried out on visceral organs of sows and piglets.
