2) Investigation items

- Concentrations of ammonia and hydrogen sulfide at a certain point in the cage

- Ammonia concentration after 24 hours by stopping the operation of the ventilation system after shipment

- Investigation of growth status and cultivation environment such as plantar inflammation

- Investigate the degree of ripeness by collecting the bottom ash by age and using the seed germination test method (Rural Development Administration)

[Experiment result]

1) Gas environment in cage

As a result of measuring the concentration of ammonia and hydrogen sulfide at a certain point and by age after chick acquisition, it was not detected until 15 days old. This is the early stage of chick growth and seems to be the result of the operation of the ventilation facility in the breeding wing.

Hydrogen sulfide was not detected during the experimental period.

* Rice husk: Rice husk treatment tool, Example 1: Example 1 flooring treatment tool

Looking at the ammonia concentration, it was investigated that the ammonia concentration was less than 20ppm (applied in 2025), which is the animal welfare breeding standard presented by the Ministry of Agriculture, Food and Rural Affairs, with a maximum of 13ppm or less.

The rice hull treatment group had a level of 3 to 13 ppm, which was slightly higher than the 1 to 11 ppm of the flooring treatment group of Example 1, and it was found that the ammonia generation inhibition ability of the flooring material of Example 1 was superior to rice hull.

In particular, odors peculiar to cages, such as molting and decomposition smell of excreted manure, did not occur at all in the bottom ash treatment area of Example 1.

2) plantar inflammation

Inflammation of the soles of the feet or chest edema by age did not occur in the rice hull and flooring treatment groups of Example 1.

3) weight

When measuring 15-day-old live weight, there is no significant difference between treatment groups at the level of 490 g. Compared to rice husk, the bottom state of the bottom ash treatment group of Example 1 was mixed with about 2 cm of powder to form small particles, so the chicken's agitation activity was good and the powder fermentation was excellent.

At 26 days of age, 6,450 animals were shipped for each treatment group, and the rice hull treatment group was 1,290 g, and the bottom ash treatment group of Example 1 was irradiated at 1,300 g

4) Decay of floor materials by age

When compost that is not well-ripened through compulsory composting of livestock manure is spread on farmland, crops are damaged due to ammonia gas, odors, and environmental pollution are generated.

5 is a graph of seed germination test results by age of rice husk and flooring treatment groups of Example 1.

The degree of ripeness is judged as the middle of ripening, which requires a little more ripening, the late ripening, when the ripening of the compost is almost finished, and the complete of ripening.

As a result of performing a seed germination test of the flooring material after broiler breeding and shipping, it can be seen that the germination index of the flooring material treatment in Example 1 was higher than that of the rice husk at all irradiation periods, and that the ripening was complete or close to the complete ripening.

5) Flooring characteristics after shipment

6 is a photograph of the rice hull treatment group after shipment, and FIG. 7 is a photograph of the flooring treatment group of Example 1 after shipment.

After shipment, the rice hull treatment group had a phenomenon in which powder was coagulated and formed a thick layer, so that it hardened very hard.

- Example 1 It can be said that it is possible to repeatedly use the flooring material by looking at the condition of the treatment tool, and it is judged that the water holding capacity is superior to that of rice husk.

- Compared to rice husk, it was expected that the particles of the bottom ash of Example 1 would be less digging (agitation action) due to the compaction of the bottom ash, but as a result of breeding, digging was easier than rice hull.

- It can be seen that the phenomenon of coagulation of chicken manure on the floor compared to rice husk was less in the bottom ash treatment area of Example 1, and there was no large-scale release of ammonia gas due to aggregation of chicken manure.

6) Ammonia gas after shipment

As a result of measuring the ammonia concentration of the rice husk treatment zone and the flooring treatment zone of Example 1 24 hours after the operation of the ventilation facility was stopped, as shown in Table 3, the flooring treatment zone of Example 1 was significantly lower, indicating that the ability to suppress odor generation was excellent. .
