There have been swine dysentery farms, to make sound treatment, disinfection, disease prevention and control, environmental control and reduce stress, etc. in order to prevent virus infection, then we would proceed from pigs physique, improve piglet feeding levels at weaning Piglet dietary nutrients in plant disease resistance, to fill gaps immune piglets, pigs enhance health and improve immunity and disease resistance and other piglets. Currently piglet prices, short supply on the market pigs, but pigs sold rate is not very high lift, and a big reason is diarrhea, prevention and control of diarrhea, nutritional disease can not be ignored. Its causes diarrhea or sow, sow viral control bad, piglets, nursery diarrhea, respiratory disease source. Plant Disease nutrients polysaccharides inhibit virus-infected cells effect on infected cells by promoting γ- interferon inhibit viral replication within infected cells, simply put, has the effect of plant polysaccharides nutrients disease virus inhibitors. Long-term use, viral diseases, such as diarrhea bed capacity, swine fever, pseudorabies, blue ear, ring, foot and mouth disease and other viral diseases can be reduced by 80%, immune monitoring results show that the use of nutrients in plant disease resistance after vaccination, antibody qualified rate, uniformity has improved significantly. Mother Tsai Kang detoxification detoxification, prevention and control of sow milk infected, enhance the ability of piglets to resist the virus, reduce the risk of viral diarrhea in piglets.
