1-2. Confirmation of development characteristics

The artificial feed composition prepared in Example 1-1 was fed to the larvae of larvae to measure the growth period by age, body weight and mortality by age. The same amount of bran (100% bran) was used as a control. The environmental conditions of the breeding room were set at 30°C, humidity 65%, photoperiod 9L/15D, and illumination 1800lux, and the experiment was performed in 3 repetitions by setting 5 heads of 40 larvae each (total 200). The results are shown in FIGS. 1 to 3.

As shown in Fig. 1, the growth period from 1 to 10 years of age of 4 types of artificial feed was 53.4±7.5 days for WF6 and 53.9±7.4 days for WF2, which was 0.3-0.8 days longer than that of the control bran (53.1±5.0 days). Confirmed. On the other hand, WFG1 (58.3±7.0 days) and WFG2 (55.9±6.2 days) with ginseng leaf powder added 2.8-5.2 days longer than the control group.

In the case of body weight, as shown in Fig.2, based on 10 years of age, four kinds of artificial feeds WF2 (58.7±43.4mg), WF6 (74.9±57.1mg), WFG1 (72.9±65.4mg) and WFG2 (46.6±20.8mg) ) Was found to be 1.8-2.9 times higher than that of the control group (26.1±12.3mg) (P=0.0001). In addition, as a result of comparison between the four artificial feeds, it was confirmed that the weight increased in the order of WF6 (2.9 times increase compared to the control group), WFG1 (2.8 times increase), WF2 (2.3 times increase), and WFG2 (1.8 times increase).

On the other hand, as a result of comparing and examining the mortality rate up to 12 years old, as shown in FIG. 3, the mortality rate for the control group and WF2 was only 10%, whereas 38% for WF6, 55% for WFG1, and 53% for WFG2 were 28 compared to the control group. It was confirmed that the mortality rate was as high as -45%.

Through the above results, it was confirmed that WFG1 and WFG2 to which ginseng leaves were added were heavier than the control group, but had a longer development period and high mortality rate, so that they were not suitable as artificial feeds for American king gooseberries. Thus, in the following experiment, an artificial feed composition was prepared based on WF2 and WF6 and used in the experiment.

Example 2. Exploration of optimal mixing ratio of bran and fish meal

2-2. Confirmation of development characteristics

The artificial feed composition prepared in Example 2-1 was fed to the larvae of the larva to measure the growth period by age, body weight by age, and mortality. As a control, the same amount of wheat bran (100% wheat bran) was used. The environmental conditions of the breeding room were set at 30°C, humidity 65%, photoperiod 9L/15D, and illumination 1800lux, and the experiment was performed in 3 repetitions by setting 3 bulbs of 40 larvae each (a total of 120). The results are shown in FIGS. 4 to 6.

As shown in Fig. 4, the growth period from 1 to 10 years of age of 2 types of artificial feed was 53.4±7.5 days for WF6 and 53.9±7.4 days for WF2, which was 0.3-0.8 days longer than that of the control bran (53.1±5.0 days). Confirmed (P=0.854).

In the case of body weight, as shown in Fig. 5, the artificial feed WF6 (74.9±57.1mg) increased 2.9 times than that of the control group (26.1±12.3mg) and WF2 (58.7±43.4mg) increased 2.3 times at the age of 10, as shown in FIG. Was confirmed (P=0.0001).

On the other hand, as a result of a comparative investigation of mortality up to age 12, it was confirmed that the control and WF2 were only 10%, whereas the WF6 was 38%, 28% higher than that of the control, as shown in FIG.

Through the above results, it was confirmed that WF6 is 0.6 times heavier than WF2, but has a disadvantage in that the mortality rate is remarkably high, so that WF2 is more suitable than WF6 as an artificial feed for American king geese.
