Abstract: Stillbirths, weak fetuses and diarrhea of weaned piglets in sows are urgent matters to be solved in the swine industry of veterinary clinics. In response to the national policy of "reducing resistance and replacing resistance" implemented in the breeding industry, this article discusses the effects of Chinese herbal compounds on the reproductive performance of sows and the growth performance of weaned piglets based on the dialectical treatment of traditional Chinese medicine. Feeding the sows (35 heads) and piglets (140 heads) that were in estrus during the same period were fed with pre-mixed feeds of traditional Chinese medicine, and continued to feed them until the end of farrowing and 30 days respectively. At the same time, the farrowing data of the sows including the number of piglets born in the litter were recorded. Litter average weight, number of stillbirths per litter, stillbirth rate, etc. and piglet growth data including initial weight, final weight, feed to meat ratio and diarrhea rate, detected by enzyme-linked immunosorbent assay (ELISA) and fluorescence quantitative PCR (RT-PCR) The secretion of IL-6, IL-1β, TNF-α, IgG, IgA, IgM in the serum of sows and IgA in the serum of weaned piglets, as well as sow circovirus, pseudorabies virus, pseudorabies virus, porcine reproductive and respiratory syndrome virus and their antibody to determine the immunity of sows. The results showed that Qiying Decoction can significantly reduce the secretion of inflammatory factors IL-6 and TNF-α in pregnant sows, reduce the stillbirth rate, weak birth rate and mortality rate of newborn piglets produced by low parity sows, respectively decreased by 1.96%, 5.83%, 8.25%, and improve the reproductive performance of sows. The combined use of Zigan Decoction and Qiying Decoction can significantly increase the IgA level of piglets in the late weaning period, reduce the rate of diarrhea and the ratio of feed to meat to improve growth performance, reduced white blood cell levels in the blood of weaned piglets and returned red blood cells to normal levels.In summary, the Chinese herbal compound Qiying Decoction and Zigan Decoction are helpful to improve the reproductive performance of sows and restore the growth performance of weaned piglets.
