Performance test

380 piglets weaned for 25 days in a pig farm were randomly divided into 19 groups, and then fed to each group with the creep prepared in examples 1-15 and comparative examples 1-4, respectively, for a daily average feed intake and diarrhea rate of 14 days, respectively.

The daily average feed intake is the total feed amount/(piglet head number multiplied by feeding days);

the diarrhea rate of piglets is the number of diarrhea pig heads in the experimental period/(number of the experimental piglet heads × number of the experimental days) × 100.

TABLE 3

By combining examples 1-3 and comparative examples 1-4 with table 3, it can be seen that according to the formula of the application, the powder material and the granular material adopt separate proportions, which can stimulate the piglet to feed, enhance the piglet feed intake and reduce the piglet diarrhea rate;

it can be seen from the combination of examples 3-7 and table 3 that the ratio of the total amount of whey powder, skimmed milk powder and chocolate powder in feed B to the total amount of whey powder, skimmed milk powder and chocolate powder in feed E affects the feed intake and diarrhea rate of piglets, and the ratio of the total amount of whey powder, skimmed milk powder and chocolate powder in feed B to the total amount of whey powder, skimmed milk powder and chocolate powder in feed E is (2-4): 1 hour, the feed intake of piglets is high, and the diarrhea rate is reduced;

by combining examples 6, 8-12 and table 3, it can be seen that the feed C in the application can improve the feed intake of piglets and reduce the diarrhea rate of piglets; the compound vitamin and the compound trace element in the application are prepared according to the formula of the application, and the effect is best; in the application, ampelopsis grossedentata flavone, enveloped sodium butyrate, enveloped tannin, bacillus subtilis, medium-chain fatty acid, montmorillonite, a complex enzyme preparation and zinc oxide are matched with one another, so that the diarrhea rate of piglets can be greatly reduced, the weaned piglets have more feed intake, less diarrhea and quick growth, and the healthy growth of the piglets is influenced due to the lack of any one of the feed intake, the diarrhea rate of the piglets and the healthy growth of the piglets; the flavoring agent, the nucleotide, the sweetening agent and the yeast culture are matched with each other, so that the piglet can be attracted to eat, and the piglet feed intake can be influenced if any one of the flavoring agent, the nucleotide, the sweetening agent and the yeast culture is lacked; combining examples 6, 13-15 and table 3, it can be seen that the ratio of the amount of the powder to the amount of the granular material affects the feed intake and diarrhea rate of piglets, the amount of the powder is greater than the amount of the granular material, which is beneficial for piglets to feed, and when the weight ratio of the powder to the granular material is (1.2-3): 1, the feed additive can promote the piglet to eat and reduce the diarrhea rate of the piglet.

The present embodiment is only for explaining the present application, and it is not limited to the present application, and those skilled in the art can make modifications of the present embodiment without inventive contribution as needed after reading the present specification, but all of them are protected by patent law within the scope of the claims of the present application.
