Feed additive with release effect and capable of treating sow metritis

Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of feed, in particular to a feed additive with sustained release effect for treating sow metritis and a preparation method thereof. Background technique [0002] Sow metritis is the inflammation of the uterus of sows after parturition and postpartum infection. The causes include: dystocia, retained placenta, prolapse of the uterus, unclean operation during midwifery, rough operation, uterine damage, postpartum infection, incomplete disinfection during artificial insemination, pathogenic bacteria in the reproductive organs or semen of boars during natural mating, inflammation Sexual secretions, etc. can cause endometritis. When sows are malnourished, emaciated, and their resistance decreases, non-pathogenic bacteria in their reproductive tracts can also cause disease. [0003] Sow metritis can be divided into acute and chronic endometritis. ①Acute endometritis: systemic symptoms are obvious, sows have elev...

AI Technical Summary

Problems solved by technology

The disease occurs mostly in the postpartum period, and may also occur in some unmated gilts. If the affected pigs are not treated in time and effectively, they will often turn into recessive or chronic infection, with reduced milk production, no milk or poor milk quality. Willing to breastfeed piglets, resulting in loose stools and stunted growth of suckling piglets; disordered estrus cycle, repeated infertility, fewer litters, stillbirth and other diseases. It is easy to be infected with other diseases and increase the loss of pig farms
