Experiment 1

Experimental animals: according to the principle of same breed and gestation, similar weight and age in days, 240 ternary hybrid weaned piglets (Du multiplied by length multiplied by size) are selected as experimental piglets.

Experiment feed: basal ration, commercially available, for routine feed (containing only conventional ingredients) for piglets.

Experiment design: the feed additives prepared in each example and comparative example were mixed with the basic daily ration at a ratio of 2 kg/ton to test piglets (kg/ton represents the amount of the experimental additives added to 1 ton of the basic daily ration), and 10 piglets were fed in 24 groups for a total period of 28 days.

Measurement indexes are as follows: during the test period, the feed intake of each piglet is recorded; weighing piglets at the beginning and the end of the test, and calculating the average daily feed intake; recording the number of diarrhea heads and the diarrhea days of each test group during the test period, and calculating the diarrhea disease rate of each test group; and recording the number of the pig influenza affected heads and the number of the pig influenza affected days of each test group, and calculating the pig influenza prevalence rate of each test group.

The specific calculation method is as follows:

the average daily feed intake is the feed intake in the piglet test period/test days multiplied by the number of the test piglets;

the diarrhea disease rate is the number of diarrhea heads multiplied by the number of diarrhea days/number of test heads multiplied by the number of test days;

the prevalence rate of swine influenza is the number of swine influenza affected heads x the number of swine influenza affected days/number of test heads x the number of test days.

The assay data for experiment 1 is detailed in table 7.
