Effect data
1. To demonstrate the effect of the feed additive for yellow-feathered broilers and the feed thereof of example 1, the inventors selected 9000 healthy Wenchang chicks as a test chick group in 5 months and 16 days of 2018.
The whole period of the breeding period is 17 weeks, and the breeding test place is Shanghai Shenghua food Limited.
Unified feeding is carried out in the brooding period (0-5 weeks old); the fed feed is a commercially available complete compound feed for the yellow-feather broilers at 0-5 weeks old, and the feeding operation method is uniformly carried out according to the feeding method of the yellow-feather broilers in the brooding period of NYT 1871-2010.
Wenchang chickens were raised in groups beginning at 6 weeks of age. Chickens of 5 weeks of age were grouped according to average body weight of the population, ensuring that the average body weight difference between the groups was insignificant, and were divided into control group 1, test group 1 and control group 1, each group being 3000, each group being subdivided into 3 replicates, each replicate being 1000. Control group 1 was fed with basal feed (i.e., commercial 6-17 week old yellow-feathered broiler complete formula feed without addition of the feed additive for yellow-feathered broiler of example 1), test group 1 was fed with the feed for yellow-feathered broiler of example 1 (i.e., the feed additive for yellow-feathered broiler of example 1 was added to basal feed), and control group 1 was fed with the poultry feed of comparative example (i.e., the poultry feed additive of comparative example was added to basal feed); the feeding operation method is uniformly carried out according to the feeding method between yellow-feather broiler chicken feeding standard NYT 1871-2010 6-17 weeks old.
Three indexes such as pre-slaughter weight, full-bore weight, feed conversion ratio and the like are measured according to the agricultural industry standard NYT823-2020 'fowl production performance noun term and metric calculation method' NYT-823-2004 fowl production performance noun term and metric statistical method, wherein 200 chickens are randomly sampled from the control group 1, the test group 1 and the control group 1 when the pre-slaughter weight and the full-bore weight are 17 weeks old for slaughter performance measurement; the hair follicle density measuring method comprises the following steps: after slaughtering and dehairing, 60 hair follicles (30 male and female) are randomly selected in each group, and the number of hair follicles in the area of 2cm multiplied by 2cm of the skin on the back on the left side is counted by taking the back midline as an axis.
Data processing and analysis were performed using SPSS22.0 software, using One Way ANOVA for statistics, and Duncan multiple comparisons were performed. Results are expressed as mean ± standard error.
The results of measurement of the production performance index at 17 weeks of age are shown in Table 1 below.
TABLE 1
Note that: the same column of data in the table indicates that the difference is significant (P < 0.05) and that the same indicates that the difference is not significant (P > 0.05), as follows.
As can be seen from the results in Table 1, at 17 weeks of age, the "pre-slaughter weight" and "full-bore weight" of test group 1 were 61.1g and 43.1g higher, respectively, than that of control group 1, and the difference was significant (P < 0.05), which indicates that the feed with the feed additive of example 1 of the present invention was used for feeding, and has a significant promoting effect on the growth and weight gain of broilers. At 17 weeks of age, the pre-slaughter weight and the full-bore weight of the test group 1 are respectively 54.3g and 45.8g higher than those of the comparison group 1, the difference is obvious (P is less than 0.05), the feed conversion rate of the test group 1 is lower than that of the comparison group 1 and the comparison group 1, and the feed conversion efficiency is improved; the three production performance indexes show that when the weight ratio of the asparagus to the rehmannia and the chrysanthemum to the bitter orange in the traditional Chinese medicine powder composition is in a specific proportion, the traditional Chinese medicine powder composition has obvious promotion effect on growth and development and weight gain of Wenchang chickens.
The index of the hair follicle of the skin of the Wenchang chicken carcass is shown in Table 2, and the hair follicle density uniformity of the test group 1 are higher than those of the control group 1 and the control group 1, so that when the weight ratio of radix asparagi to rehmannia, and the weight ratio of chrysanthemum to fructus aurantii in the traditional Chinese medicine powder composition is in a specific proportion, the Wenchang chicken can obviously improve the pore density of the skin unit area of the broiler chicken and reduce the hair follicle density difference among chicken individuals, and the aim of improving the appearance of the chilled fresh broiler chicken carcass in nutrition is fulfilled.
TABLE 2
2. To demonstrate the effect of the feed additive for yellow-feathered broilers and the feed thereof of example 2, the inventors selected 9000 healthy Guangxi Sanhuang chickens as the test chicken flock on day 7 and 12 of 2019.
The only difference from the first part described above is that: at 6-17 weeks of age, chickens over 5 weeks of age were randomly assigned to control group 2, test group 2 and control group 2, each group being divided into 3000 animals, each group being subdivided into 3 replicates, each replicate being 1000 animals. Control group 2 was fed with basal feed (i.e., commercial 6-17 week old yellow-feathered broiler complete formula feed without addition of the feed additive for yellow-feathered broiler of example 2), test group 2 was fed with the feed for yellow-feathered broiler of example 2 (i.e., the feed additive for yellow-feathered broiler of example 2 was added to basal feed), and control group 2 was fed with the poultry feed of comparative example (i.e., the poultry feed additive of comparative example was added to basal feed).
Other specific experimental processes and data statistics methods are basically the same as those of the first part, and detailed descriptions thereof are omitted.
The results of measurement of the production performance index at 17 weeks of age are shown in Table 3 below.

As can be seen from the results in Table 5, at 17 weeks of age, the "pre-slaughter weight" and "total clean bore weight" of test group 3 were 56.8g and 46.1g higher, respectively, than that of control group 3, and the difference was significant (P < 0.05), which indicates that the feed added with the feed additive for yellow-feather broilers of example 3 of the present invention had a significant promoting effect on the growth and weight gain of broilers. At the age of 17 weeks, the 'live weight' and the 'slaughter weight' of the test group 3 are respectively 59.7g and 41.9g higher than those of the comparison group 3, the difference is obvious (P is less than 0.05), the feed conversion rate of the test group 3 is lower than that of the comparison group 3 and the comparison group 3, and the feed conversion efficiency is improved; the three production performance indexes show that when the weight ratio of the asparagus to the rehmannia and the chrysanthemum to the bitter orange in the traditional Chinese medicine powder composition is in a specific proportion, the traditional Chinese medicine powder composition has obvious promotion effect on growth and development and weight gain of the pheasant.
The skin hair follicle indexes of the chicken carcasses of the Ma chickens are shown in Table 6, and the hair follicle density uniformity of the test group 3 are higher than those of the control group 3 and the control group 3, so that when the weight ratio of radix asparagi to rehmannia root to chrysanthemum to fructus aurantii in the traditional Chinese medicine powder composition is in a specific proportion, the chicken carcasses of the Ma chickens can be obviously improved in pore density of the chicken carcasses per unit area, the hair follicle density difference among chicken individuals is reduced, and the aim of improving the appearance of the chilled fresh chicken carcasses is fulfilled.
