Embodiment 1

[0091] Combining ability was used to determine the best combination for chicken breed selection, and Xiao Shaoxing No. 1 chicklings, Shenhuang×Shenhong combination were selected for a three-month feeding experiment.

[0092] The diet in feed nutrition formulation was: protein 19%, protein-energy ratio 15.08 in early stage, protein 17% in mid-term, protein-energy ratio 13.50. In the later stage, the protein is 15%, and the protein-energy ratio is 11.90%.

[0093] The feeding operation was carried out in accordance with the feeding management regulations, and the feeding results were as follows:

Embodiment 2

[0100] Example 2 In this experiment, green feed additives were used to replace antibiotics and chemical drugs to eliminate the effects of antibiotics and synthetic drugs on chickens.

[0101]In the experiment, 110 1-day-old Shenguang × Hongbao hens provided by Shanghai Xiao Shaoxing Breeding Chicken Farm were selected and divided into two groups, with five replicates in each group, 11 birds in each replicate, and 55 birds in each group. The control group added 55 mg / kg of salinomycin and 50 mg / kg of aureomycin to the diet, and the test group added 1000 mg / kg of the green feed additive of the present invention to the diet, with acidic probiotics in the early stage and alkaline photosynthetic bacteria in the later stage. The test chicken was raised in a two-layer cage of 100 × 85 centimeters, and the feeding operation was carried out according to the present invention, and the feeding period was 90 days.
