Feeding tests are carried out according to the feeding modes of the Jiaji ducks of the examples 1-3 and the comparative examples 1-4, 280 healthy ducklings of 1 day old are selected and randomly divided into 7 groups of 40, and the average weight of each group is measured; before the test, cleaning and disinfecting the duck shed, the trough and the water feeder, recording daily feed intake, calculating feed conversion ratio according to average daily gain and average daily feed intake, and reflecting whether marketing can be accelerated or not according to the feed conversion ratio and slaughter rate of the Jiaji ducks of 56 days old. The slaughter rate is determined by reference to the poultry production performance noun terms and measures statistical method.
TABLE 1
Average daily gain (g) Average daily intake (g) Material to weight ratio Dressing percentage (%)
Example 1 41.36 158.82 3.84 84.45
Example 2 41.08 152.82 3.72 84.21
Example 3 41.75 162.83 3.90 83.28
Comparative example 1 38.63 164.56 4.26 69.67
Comparative example 2 40.49 163.18 4.03 74.52
Comparative example 3 39.69 165.47 4.17 83.34
Comparative example 4 36.74 150.81 4.10 76.55
As can be seen from Table 1, the feed-to-weight ratios of examples 1-3 are significantly lower than comparative examples 1-4, while the dressing percentage is significantly higher than comparative examples 1-4. Compared with the comparative example 1, the traditional Chinese medicine compound can reduce the material-weight ratio of the Jiaji duck in slaughtering and improve slaughtering rate of slaughtering; compared with the comparative example 2, the addition of the Chinese medicinal composition containing the Chinese fevervine herb leaves can further reduce the material-weight ratio of the Jiaji ducks in slaughtering and improve slaughtering rate of Jiaji ducks in slaughtering.
According to the comparison of the comparative examples 3 to 4 in the month of example 1, the feeding times and the feeding amount of the Jiaji ducks every day and the feeding temperature of the ducklings influence the slaughtering material weight ratio and the slaughtering rate of the Jiaji ducks.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
