Therefore, by applying the foamed rubber composition to the outlet of the food storage unit, it is possible to reduce noise and feed the animals without being surprised.

(Experimental Example 2)

When the anti-skid pad was attached to the food supply according to the present invention, a work efficiency evaluation experiment was performed to confirm that the food supply efficiency is improved. First, the food was supplied 20 times using the food supply unit without the anti-skid pad, and then the food was supplied 20 times using the food supply unit with the anti-skid pad attached. Table 2 shows the number of times the food slipped.

Feeding frequency (times) Number of slips (times) Pad × 20 5 Pad ○ 20 0

As described above, the number of times the food slipped and fell before reaching the target point out of 20 feeding times to the food supply section without the non-slip pad was fed, and the food was fed to the food supply section with the anti-skid pad attached. During the 20 feeding periods, the food never slipped. Therefore, by attaching an anti-skid pad to the food supply, it is possible to accurately feed the target livestock without slipping even in the operation of the food supply that is not smooth.

(Comparative Example 1, Comparative Example 2, Comparative Example 3)

The antimicrobial coating layers of Comparative Example 1, Comparative Example 2, and Comparative Example 3 were prepared as follows by varying the amount of antimicrobial material added compared to the antibacterial coating layer of the present invention.

(Parts by weight) 8 5 10 8

(Experimental Example 3)

In order to confirm the antimicrobial effect of the antimicrobial coating layer according to the present invention, a fungal detection experiment of the antimicrobial coating layer composition (Example, Comparative Example 1, Comparative Example 2, Comparative Example 3) prepared by the above process was performed. The bacteria detection test was performed in a sterile worktable, and a dry film medium for Staphylococcus aureus was used.

First, 9 mL of sterile water is added to 1 g of the antimicrobial coating layer composition to make a 10-fold diluted solution evenly mixed using a homogenizer. After transferring the sample dilution solution to a sterile test tube, inoculate Staphylococcus aureus to a concentration of 3.0 × 10 ² CFU / mL and mix using a Voltex Mixer. After inoculating 1 mL of the completed sample solution in a dry film medium, transfer it to an incubator and incubate at 35 ° C. for 48 hours. After 48 hours, the number of colonies formed on the dry film medium was read to calculate the rate of change of the number of bacteria. The results are shown in Table 4 below.

Example Comparative Example 1 Comparative Example 2 Comparative Example 3 Total powder 5.7 3.6 7.1 5 Cudrania extract 2.3 1.4 2.9 3 Antibacterial material

(CFU / mL) <10 1.7 × 10 ² <10 <10
Equal number
Rate of change -99% -44% -99% -99%

As in the above results, in the case of Comparative Example 1, although the inoculated bacteria concentration was reduced, Staphylococcus aureus remained, and in Examples, Comparative Examples 2 and 3, the bacteria were almost eliminated. However, in the case of Comparative Example 2, when the film was produced, the amount of antimicrobial material was added, so it was not uniformly mixed and the surface of the film was roughly unsuitable for application. There is a problem that does not melt evenly when processing the antimicrobial coating layer while a part of the clump. Therefore, the antibacterial coating layer according to the present invention is suitable for application and exhibits an antibacterial effect in food storage.
