Embodiment 1

[0056] In a duck breeding base, ducklings are fed with organic selenium-rich duck feed every day. The duck feed consists of the following raw materials by weight: 2 parts of the aforementioned selenium-enriched cornmeal, 1 part of selenium-enriched broccoli powder, 1 part of selenium-enriched soybean meal, 8 parts of fish meal, 15 parts of bran, 15 parts of rice, cotton meal 15 parts, 3 parts of soybean oil, 11 parts of full-fat soybean powder, 3 parts of shellfish powder, 18 parts of rapeseed meal, 2 parts of table salt, 3 parts of calcium hydrogen phosphate, 3 parts of compound minerals for meat ducks, made into organic selenium-rich duck feed, The total selenium content of the feed was 311.3 μg / kg, of which selenomethionine accounted for 64.6% of the total selenium, and selenocysteine ​​accounted for 4.6% of the total selenium. When the duck meat is waiting for market slaughter, the total selenium content and the quality of the duck meat are tested, and the production perfo...

[0060] In a duck breeding base, ducklings are fed with organic selenium-rich duck feed every day. The duck feed consists of the following raw materials by weight: 3 parts of the aforementioned selenium-enriched cornmeal, 2 parts of selenium-enriched broccoli powder, 1 part of selenium-enriched soybean meal, 8 parts of fish meal, 14 parts of bran, 14 parts of rice, cotton meal 15 parts, 3 parts of soybean oil, 11 parts of full-fat soybean powder, 3 parts of shellfish powder, 18 parts of rapeseed meal, 2 parts of table salt, 3 parts of calcium hydrogen phosphate, 3 parts of compound minerals for meat ducks, made into organic selenium-rich duck feed, The total selenium content of the feed was 431.6 μg / kg, of which selenomethionine accounted for 67.5% of the total selenium, and selenocysteine ​​accounted for 5.3% of the total selenium. When the duck meat is waiting for market slaughter, the total selenium content and the quality of the duck meat are tested, and the production perf...

Embodiment 3

[0065] In a duck breeding base, ducklings are fed with organic selenium-rich duck feed every day. The duck feed consists of the following raw materials by weight: 4 parts of the aforementioned selenium-enriched cornmeal, 3 parts of selenium-enriched broccoli powder, 2 parts of selenium-enriched soybean meal, 7 parts of fish meal, 13 parts of bran, 13 parts of rice, cotton meal 14 parts, 3 parts of soybean oil, 12 parts of full-fat soybean powder, 3 parts of shellfish powder, 18 parts of rapeseed meal, 2 parts of table salt, 3 parts of calcium hydrogen phosphate, 3 parts of compound minerals for meat ducks, made into organic selenium-rich duck feed, The total selenium content of the feed was 621.4 μg / kg, of which selenomethionine accounted for 69.4% of the total selenium, and selenocysteine ​​accounted for 6.2% of the total selenium. When the duck meat is waiting for market slaughter, the total selenium content and the quality of the duck meat are tested, and the production per...

Abstract

The invention discloses a duck feed rich in organic selenium. If the feed is fed from young ducks, the production performance, the meat selenium content and the duck meat quality of meat ducks can be effectively improved. The total selenium content of the duck feed rich in organic selenium is 300-1000 microgrammes/kg, wherein selenomethionine accounts for 60-80% of the total selenium ratio, and selenocysteine accounts for 1-10% of the total selenium ratio. According to the feed, the immunity, the production performance, the meat selenium content and the duck meat quality of the meat duck can be effectively improved, and the duck feed can be widely applied to the cultivation of the meat duck.

Description

technical field [0001] The invention relates to the field of poultry feed, in particular to an organic selenium-rich duck feed added with high-selenium grains to improve the production performance of meat ducks and the technical field of duck meat quality. Background technique [0002] Selenium is an essential trace element in animals. It has strong antioxidant properties and is an important part of the antioxidant enzyme glutathione peroxidase (GSH-PX) in the body. It can improve the body's immunity, Reduce morbidity, improve production performance, improve meat quality evaluation, and at the same time antagonize heavy metals in the body. Selenium is used in poultry farming, which can remove free radicals in poultry and make animals more energetic. [0003] Selenium is generally divided into two categories: inorganic selenium and organic selenium: the former includes selenate, selenite, etc. Inorganic selenium is poorly absorbed by humans and animals, and has a high risk o...
