2.5.1 Effect of Probiotics on broiler chicken production Performance
TABLE 1 Effect of prebiotics on broiler productivity
Note: the SEM is the standard deviation of the sample mean, is a scale for describing the dispersion degree of mean sampling distribution and measuring the magnitude of mean sampling error, and reflects the variation between sample means.
As can be seen from Table 1, after the probiotics are added, the average body weight of the broiler chickens spot-checked at the age of 14 days and the broiler chickens spot-checked at the age of 28 days are higher than that of the control group, and are respectively increased by 1.85 percent and 5.50 percent. At the end of the test (42 days old), the average end body weight (42 days old) of the experimental group was 65.81 g, which was increased by 2.08% compared with 64.47 g of the control group. The average death and wash number of each crop in the experimental group and the control group is 932.5 and 1107.25 respectively, the experimental group is reduced by 174.75 compared with the control group, and the total death and wash rate is reduced from 6.78% to 5.71%.
