At present, the feed used by many domestic free-range geese is composed of green vegetables and rice. The weight gain of geese is slow. Even if some small-scale geese farms adopt the method of shepherding and grazing, they have met the habit of geese to a certain extent, but because Water grass and green materials are bulky and relatively low in nutrients, which results in poor uniformity of growth, long feeding periods, and high material consumption. First, formulate the principle of goose feed formula 1, according to goose breeds, development stages and production purposes to choose the appropriate feeding standards, both to meet the physiological needs of geese without causing nutritional waste. 2. Based on local resources, reduce costs as much as possible on the premise of ensuring nutrient content, so that farmers can obtain greater economic benefits. 3, choose a good palatability and a certain amount of raw materials to ensure that the goose eats enough nutrition every time. 6. The quality of the selected raw materials is better, there is no mildew, and there is no pollution from pesticides. Second, the preparation of goose feed Seed and processing by-products 30 to 70%, tubers and their processing by-products (dry weight) 15 to 30%, animal protein 5 to 10%, plant protein 5 to 20%, green feed and grass powder 10 to 30 Percentage of calcium, calcium powder and salt, and some additives are used as required. (1) Powder mixing: The raw materials are processed into dry powder and then mixed uniformly, and pressed into pellets for feeding. This form not only saves time and labor, but also prevents goose picky eaters. (3) Fine and coarse material mixing: The concentrate feed is processed into powder and mixed with crushed green grass, green vegetables or multi-rooted rhizomes, calcium powder and additives are mixed in the powder, and the sand can be used in another. The container is placed. Feeding geese with the latter two mixed forms of feed can easily lead to excessive or insufficient intake of certain nutrients.

4, with a variety of raw materials, in order to play a complementary role in mutual nutrition.
5. Control the amount of certain feed ingredients. If leguminous hay powder is rich in protein, the amount in the diet can be 15 to 30%; feather powder, blood meal, etc. although the protein content is high, but the digestibility is low, and the added amount should be below 5%.

(2) Mixing of powder and granules: that is, the glutinous grains in the diet are still granular, mixed together and fed several times a day, and the mixed powder containing animal protein, calcium powder, salt, and additives is additionally supplemented.
The collected nasopharyngeal swab samples should be transported at 2°C to 8°C and sent for inspection immediately, and the sample delivery and storage time should not exceed 48 hours.
[Testing method]
1. Before sampling, mark the relevant sample information on the label of the sampling tube.
2. According to different sampling requirements, use a sampling swab to sample in the nasopharynx.
3. The specific sampling methods are as follows:
a) Nasal swab: Gently insert the swab head into the nasal palate, stay for a while and then slowly turn to exit. Wipe the other nostril with another swab, immerse the swab head in the sampling solution, and discard the tail.
b) Pharyngeal swab: Wipe bilateral pharyngeal tonsils and posterior pharyngeal wall with a swab, also immerse the swab head in the sampling solution, and discard the tail.
4. Quickly put the swab into the sampling tube.
5. Break the part of the sampling swab higher than the sampling tube, and tighten the tube cover.
6. Freshly collected clinical specimens should be transported to the laboratory within 48 hours at 2°C to 8°C.
[Explanation of test results]
After the sample is collected, the sampling solution turns slightly yellow, which will not affect the nucleic acid test result.
[Limitations of the test method]
1. For samples that are seriously contaminated due to improper storage after collection, the final test results will be affected.
2. If the sample is not stored at the specified temperature, the final test result will be affected.
