Chitosan oligosaccharide laying hen feed and preparation and use method thereof

Abstract

The invention provides chitosan oligosaccharide laying hen feed which is prepared from laying hen feed and a premix material in parts by weight. The laying hen feed is prepared from the following components in parts by weight: 62-64 parts of corn, 16-18 parts of bean pulp, 6-8 parts of rape seed dregs, 1-2 parts of fish meal, 1-2 parts of calcium bicarbonate, 3-4 parts of shell powder, 4-6 parts of talc powder, 0.4-0.6 part of soybean oil, 0.5-0.6 part of salt, 3-4 parts of wheat bran, 4-5 parts of sorghum flour and 3-4 parts of blood powder; and the premix material is prepared from the following components in parts by weight: 4-6 parts of laying hen vitamin, 3-5 parts of Vc, 20-22 parts of choline chloride, 1-2 parts of antioxidizing amine, 60-70 parts of protein powder and 1-2 parts of oligosaccharins. The chitosan oligosaccharide laying hen feed provided by the invention has the advantages of simple process and convenience in manufacture and use, and the oligosaccharins which is rich in chitosan oligosaccharide is added into the feed for feeding the laying hen so that the nutrition component of the obtained egg products contains the chitosan oligosaccharide.

Description

Technical field: [0001] The invention relates to the technical field of feed for poultry feeding, in particular to a chitosan oligosaccharide feed for laying hens and its preparation and use methods. Background technique: [0002] During the growth and development of laying hens, a lot of energy and other nutrients are needed. If the feed energy is insufficient or lacks certain nutrients, it will cause metabolic problems in the laying hens, resulting in slow growth and development, weight loss, and immunity. Decline, low egg production rate, low nutritional quality of eggs and other problems. In addition, with the improvement of people's living standards, people's requirements for egg quality are also getting higher and higher. Therefore, by adding various trace elements and other minerals in the chicken feed, the eggs produced by the chickens are rich in one or more minerals, thereby supplementing the human body with mineral elements to overcome the human body. Mineral or...
