Embodiment 1
[0035] Example 1 Production of Drinking Water or Feed Additive Composition
[0036] All crude drugs were purchased from Korea as test materials. After adding 15 l of water to approximately 2,456.5 g of carefully selected crude drugs having the composition shown in Table 1 below, they were left to stand at room temperature for 1 hour. Next, hot water extraction was performed at 115° C. for 3 hours to obtain a crude drug extract with a volume of about 11 liters, and then freeze-dried to obtain a freeze-dried product of about 9.6 g. The above crude drug extracts were used in the present invention, and the test substances were added to water at a concentration of 1% and used in experiments.

Embodiment 2
[0040] Embodiment 2 weight gain rate evaluation
[0041] RATIO week and DIFF week
[0042] 20-day-old weaned piglets with respiratory symptoms, co-infection of PRRSV and PCV-2 virus confirmed in serological examination, completely asymptomatic, and normal vital signs are about 60-70% as weak piglets , and run the experiment after acclimatizing it to the new environment for a day. Experimental animals were reared in three piggery houses with sufficient space at a temperature of 23±3°C and a humidity of 50±5%. The test substance produced in the above-mentioned Example 1 was used in the experiment, and it was implemented in strict accordance with the "mixing and preparation of the test substance (NITR / SOP / TSB / 002_02)" in the standard operating procedure of the Food and Drug Safety Evaluation Institute. The interweek weight gain rate was calculated by weekly body weight measurement, and the weight gain rate was measured for 4 weeks until the weaned piglets reached 49 days of ag...
Embodiment 3
[0053] Embodiment 3 vital signs evaluation
[0054]The scoring method of vital signs is a reference paper (Halina M.Zaleski, Roger R.Hacker, Variables related to the progress of parturition and probability of stillbirth in swine, The Canadian Veterinary Journal, 1993February;34(2):109-113 ) method was changed, and a score of 0-12 was scored based on muscle tone, skin condition, ratio of active time to lying time within 30 minutes, presence or absence of clinical symptoms, feed intake, and drinking water intake Fraction. The scoring of the above vital signs was carried out at the 3rd, 7th, 10th, 14th, 17th, 21st, 24th, and 28th day of age.
[0055] The results showed that until the 0th week and the 1st week of the experiment, the vital signs of the experimental group did not increase significantly, but after the 2nd week, the scores of vital signs increased significantly compared with the negative control group ( Figure 6 to Figure 9 ).
