Feed feeding effect test
The feed feeding effect verification is carried out on the feed for the biological enzymolysis broussonetia papyrifera prepared in the examples 2-4 and the comparative examples 1-3. Selecting 120 young ducks which are healthy in growth and 40-70 g in weight, randomly dividing the young ducks into 6 groups, wherein each group comprises 20 ducks which are respectively an experimental group 1-3 and a comparative group 1-3, correspondingly feeding the biological enzymolysis broussonetia papyrifera feed prepared in the examples 2-4 and the comparative examples 1-3, and the biological enzymolysis broussonetia papyrifera feed can be freely drunk for 30 days, and is fed for 3 times a day, wherein the time is 9-10 am, 2-3 pm and 7-8 pm. And testing the average daily feed intake, the average daily gain and the material weight ratio. Wherein the average daily gain is weighed between 8 and 9 in the morning, and the average daily gain of each group is calculated; the average daily feed intake is divided by the average daily gain. Specific detection results are shown in table 1:
TABLE 1 feed feeding effect test results
Test set | Average daily food intake (g) | Average daily gain (g) | Material to weight ratio |
Experimental group 1 | 158 | 92 | 1.72 |
Experimental group 2 | 156 | 90 | 1.73 |
Experimental group 3 | 157 | 88 | 1.78 |
Comparative group 1 | 146 | 68 | 2.15 |
Comparative group 2 | 153 | 62 | 2.47 |
Comparative group 3 | 148 | 66 | 2.24 |
As can be seen from the table above, the average daily feed intake and average daily gain of the ducks fed by the experimental group of the biological enzymolysis paper mulberry feed are superior to those of the comparative group, and the material weight ratio is smaller than that of the comparative group, so that the biological enzymolysis paper mulberry feed of the experimental group is more palatable, and has more obvious effects of enhancing nutrition and increasing weight. The comparative group 1 and the comparative group 3 do not adopt the secondary crushing fermentation equipment in the embodiment 1, so that the feed is easy to agglomerate, the nutrient components are not uniformly dispersed, and the daily gain effect is reduced; compared with the group 2, due to the lack of partial microbial inoculum, the nutrient substances such as protein, cellulose, vitamins and the like in the broussonetia papyrifera leaves cannot be completely decomposed into saccharides, lipids, lactic acid and amino acid, the loss of nutrient components is large, and the daily gain effect is obviously reduced.
Meat conventional ingredient test
After the fed duck is slaughtered, selecting a duck meat part for detecting the moisture content, the crude protein content, the intramuscular fat content and the ash content, wherein the specific detection results are shown in a table 2:
TABLE 2 results of conventional meat ingredient testing
As can be seen from the table above, the duck fed with the broussonetia papyrifera feed subjected to biological enzymolysis by the experimental group has the advantages of higher crude protein content, lower intramuscular fat content, lower ash content and higher nutritional value in the conventional meat components.
