The experimental data showed that adding licorice crude extract powder to pig diet had obvious appetite and disease resistance. The stress reaction decreased by 18.92%, the incidence of dysentery decreased by 14.29% and the survival rate increased by 7.14%. At the same time, it has good antibacterial effect on staphylococcus, Escherichia coli, typhoid bacillus, mycoplasma, streptococcus and so on have inhibitory effect. Five days before and after immunizing pigs, adding licorice crude extract in water or mix (400 grams per ton of feed) can activate various immune organs in pigs, accelerate the production of vaccine antibodies, and shorten the immune blank period.
Support gastrointestinal health

Antiviral & Antibacterial
Licorice root crude extract has become the preferred natural additive to combat viral diseases in livestock and poultry and has no toxic side effects, and its efficacy has also been recognized by breeding.

After adding licorice root extract (400 grams per ton of feed) to the drinking water of sick pigs for about 7 days in the course of disease, the drinking water of sick pigs with licorice crude extract can increase the cure rate by 33% and recover faster than the control group.
Improves hair and skin quality
Licorice has strong anti-inflammatory activity, similar to the effect of deoxycorticosterone, has an obvious effect on the symptoms of adrenal cortical dysfunction, can promote the formation and secretion of stomach mucus, and prolong the life of epithelial cells.

Improve growth performance
The addition of licorice extract in feed can effectively promote the growth performance of animals. The results showed that adding licorice extract powder to feed could significantly increase the average daily gain of pigs, reduce the feed-to-gain ratio, and prove its growth-promoting effect from the metabolic level. Licorice extract also has an obvious feeding effect, the use of licorice extract in more than 150 pounds of fattening pig farms, 400 grams per ton of mix, can significantly increase feed intake, the pig herd is in good condition, and can be about 10 days in advance of fattened stock.
