Problems solved by technology

The extensive use of unconventional feeds in commercial feeds leads to the deposition of anti-nutritional factors, which directly affects the freshness of duck eggs, and ultimately shortens the storage period of duck eggs, which is not conducive to long-term preservation of duck eggs, and has a negative impact on the reproductive performance of laying ducks.

Abstract

The invention discloses laying-duck feed capable of improving freshness of duck eggs in a storage period and reproductive performance of laying ducks and an application of the laying-duck feed and belongs to the field of feed. The laying-duck feed per kilogram contains the following ingredients: corn, bean meal, dual-low vegetable meal, cottonseed meal, rice bran meal, coarse-grain stone powder, soybean oil, dicalcium phosphate, L-lysine hydrochloride, DL-methionine, common salt, multivitamin-micro-element premix and a free-radical clearing compound agent. According to the laying-duck feed and the application of the laying-duck feed, through improving a feed formula and adjusting feed composition, the laying-duck feed is free of exogenous antibiotics, health-care drugs and pigment additives; after carrying out feeding by using the feed, the following effects can be achieved: production performances such as laying rate and feed-egg ratio of the laying ducks are all superior to those of market goods production materials, and the feed cost is close to that of goods materials; the freshness of the duck eggs produced by using the feed prepared by the technology can be improved by 8.5%; the storage period of the duck eggs is prolonged by about 1 week compared with that of the duck eggs produced by using ordinary commercial feed; the reproductive function of the laying ducks is improved.

Description

technical field [0001] The invention belongs to the field of feed and relates to a feed formula, in particular to a laying duck feed which improves the freshness of duck eggs during storage and the reproductive performance of laying ducks and an application thereof. Background technique [0002] Duck eggs are rich in unsaturated fatty acids that are beneficial to human health, and as a "cool" food, they have certain health care functions, and are very popular among southerners. Duck egg products have a large consumer market in southern regions, Hong Kong, Macao, Taiwan, and Southeast Asia. . Egg freshness is an important economic index to measure the quality of duck eggs, and it is also one of the main factors affecting the sales of duck eggs. At present, freshness is regarded as an important indicator of fresh egg grading standards in the world. However, during production, with the prolongation of storage time, the freshness of duck eggs will decline, especially in the hi...
