The intestinal health is improved. The disease incidence of diarrhea and the feed conversion ratio are decreased at the same time.

Comparative Embodiment 1

(19) Experiment conditions are the same as Embodiment 2. Compared with other nutrition supplements of Embodiments 1-6, a formula is shown as follow:

(20) bovine colostrum from animal source accounting for 60%, soybean protein from botanic source accounting for 35%, yeast extracts from microorganism accounting for 10%. The effects are shown in Table 6:

(21) TABLE-US-00006 TABLE 6 Using effects of nutrition supplement in Comparative Embodiment 1 feed conversion daily average feed ratio weight intake (feed intake/ diarrhea gain (g/d. of each weight gain rate each) (kg/d) of piglet) (%) feed added with 0.1% 235.6 0.285 1.21 3.33% of the nutrition supplement of Comparative Embodiment 1

Comparative Embodiment 2

(22) A commercially available dried larva of Hermetia illucens L. was used as the nutrition supplement. It was added in a weight percentage of 0.1% into the commercially available feed special for newborn piglets and fed to the newborn piglets for two weeks. The test results are shown in Table 7:

(23) TABLE-US-00007 TABLE 7 Influence of the nutrition supplement of Comparative Embodiment 2 on growth performances of newborn piglet Feed-meat conversion average feed ratio daily weight intake (feed intake/ diarrhea gain (g/d. of each weight rate each) (kg/d) gain of piglet) (%) feed added with 232.7 0.280 1.18 2.33% 0.1% of the nutrition supplement of Comparative Embodiment 2

(24) It can be seen in Table 7 that using the nutrition supplement added with 0.1% of the dried larva of Hermetia illucensL. is compared with using eggs of Hermetia illucensL. as the nutrition supplement in Embodiment 2. The weight gain, the feed intake and a feed utilization of the latter are obviously improved, also the diarrhea rate is reduced.

(25) Obviously, the above embodiments are only examples for clearly specifying the present invention but not for limiting the implementations. For those skilled in the art, changes or variations in different forms based on above can still be made. It is unnecessary or unable to give all implementations here.
