Antibiotic-free composite premix feed for laying hens at laying period as well as preparation method and application of antibiotic-free composite premix feed

Abstract

The invention belongs to the technical field of feeds, and relates to an antibiotic-free composite premix feed for laying hens at a laying period, as well as a preparation method and the application of the feed. The feed consists of the following components in parts by weight: 5-10 parts of corn gluten meal, 8-25 parts of peanut meal, 5-10 parts of rice bran, 15-25 parts of sesame seed meal, 20-50 parts of dietary fibers, 1-10 parts of soybean oil, 5 parts of a 0.5% compound premix, 8-15 parts of stone powder, 8-15 parts of dicalcium phosphate, 2.5-4.5 parts of table salt, 1-3 parts of lysine, 1-3 parts of threonine, 1-3 parts of methionine, 0.1-0.5 parts of Nutri. P namely tannic acid, 1-3 parts of yeast hydrolyate, 0.3-2 parts of yeast cell wall powder, 0.1-0.5 part of selenium yeast, 0.1-0.5 part of zinc methionine, 0.2-0.5 part of hemoprotein, 0.2-0.5 part of a compound enzyme preparation, 0.8 part of choline chloride and 0.2 part of 10000 u / g phytase. Through the adoption of the antibiotic-free composite premix feed, the laying rate, the egg production and the egg weight can be notably increased.

Description

technical field [0001] The invention belongs to the technical field of feed, and in particular relates to a compound premixed feed for laying hens without antibiotics, and relates to a preparation method and application of the feed. Background technique [0002] With the expansion of laying hen breeding scale, the number of medium and large laying hen farms using 1% laying hen premix, 3% laying hen premix and 5% laying hen premix is ​​increasing day by day, even reaching more than 40%. It was found at the breeding site that the quality of eggshells in chicken farms using premixed materials is poor, the feces are thin, and the death rate is high, which seriously affects the economic benefits of laying hens. The hidden loss of each laying hen is at least 5 yuan per year, accounting for More than 30% of the profit of laying hens. During the breeding process of laying hens, they are polluted by Escherichia coli, Salmonella, etc., and the incidence of respiratory diseases, intes...

Problems solved by technology

The components of this invention are too simple, which belong to conventional feed, and the biologically active substances such as enzyme preparations and microecological preparations to improve digestibility are not used, and the degree of standardization is low, which cannot meet the nutritional needs of laying hens during the laying period. Egg production uses body reserves to meet the maximum egg production demand at the expense of health, resulting in substandard body weight and reduced disease resistance

[0014] To sum up, currently commonly used premixes for laying hens are nutritionally unbalanced, which is likely to cause serious problems such as poor eggshell quality, thin feces, high mortality rate, and large dosage of breeding chemicals in chicken farms using premixes. Affecting the economic benefits of laying hen farming and many other issues
