Abstract
The invention discloses a selenium-enriching laying duck feed and a breeding method of a selenium-enriching laying duck. Per 1000 parts by weight of selenium-enriching laying duck feed contains 0.01-0.05 part by weight of selenium chitosan, 0.1-0.5 part by weight of lactic acid bacillus, 0.002-0.006 part by weight of vitamin E, 0.1-0.5 part by weight of fructo-oligosaccharide and 1.0-2.0 parts by weight of corncob powder. The laying duck is fed with a basic ration compound feed, i.e., the laying duck is fed with the basic ration compound feed after being uniformly mixed with a premix containing the selenium chitosan, thelactic acid bacillus, the vitamin E, the fructo-oligosaccharide and the corncob powder. According to the selenium-enriching laying duck feed, the dynamic balance of selenium in the duck within an egg laying period can be maintained, high-selenium eggs are continuously produced, and the Haugh unit reduction of the eggs in a storage process is delayed so that the refreshing time is prolonged, the egg hatching rate is increased, the eggshell thickness, the protein height, the yolk index and the yolk color are enhanced, the duck egg quality is improved, the feed intake, laying rate and egg weight of the ducks are increased, the feed-gain ratio is reduced, and the feed utilization rate is increased.
Description
technical field [0001] The invention belongs to the technical field of animal husbandry production, and in particular relates to a selenium-enriched laying duck feed and a feeding method for selenium-enriched laying ducks of the health-care poultry egg production technology. Background technique [0002] Modern medical research has proved that selenium is an essential trace element for the human body and plays an important role in the human body. A certain amount of selenium can prevent diabetes, cataracts, cardiovascular diseases, prevent Keshan disease, Kaschin-Beck disease, arthritis, delay aging, antagonize heavy metals such as mercury, tin, thallium, and lead, form metal-selenoprotein complexes, and detoxify. Selenium has selective killing and inhibitory effects on liver cancer cells, and selenium supplementation is also an effective measure to prevent and treat liver diseases. [0003] According to the "Atlas of Local Diseases and Environmental Factors of the People's...
