Embodiment 1
[0120] A method for breeding laying hens, dividing the breeding stages of laying hens into six stages and setting basic nutritional requirements in each stage, including:
[0121] (1) With 0-15 days of age as the opening stage, feed full-price nutritious feed, in which the mass fraction of protein is 20%, the energy is 2900 kcal / kg, the mass fraction of methionine is 0.45%, and the mass fraction of lysine is 1.1%, the mass fraction of calcium is 0.9%, the mass fraction of available phosphorus is 0.45%, and the mass fraction of salt is 0.3%. Choose high-quality raw materials with high nutrition, easy digestion and absorption, and low anti-nutritional factors, such as expanded corn, expanded soybeans, soy milk powder, imported fish meal, immune globulin, etc. At this stage, the daily feed intake is about 10 grams / head / day.
[0122] (2) 16-70 days old as the brooding stage, 16-35 days old full price nutrient feed, in which the mass fraction of protein is 18.5%, energy is 2900 kcal / kg...
Embodiment 2
[0136] The full-price nutrient feed of stage (4) in Example 1 is replaced with the following formula, and the rest is the same as Example 1. The formula includes the following components by weight:
[0137] 26 parts of corn, 40 parts of wheat, 15 parts of soybean meal, 4 parts of cotton meal, 2 parts of fish meal, 2 parts of insect meal, 1 part of vegetable oil, 5 parts of calcium additives, 0.25 parts of salt, 0.2 parts of lysine, 0.12 parts of methionine, 0.3 parts of compound trace elements, 0.03 parts of compound vitamins, 1 part of calcium hydrogen phosphate, 0.08 parts of choline chloride, 0.02 parts of enzyme preparations, 3 parts of Chinese herbal medicine additives; the Chinese herbal medicine additives are made of the following parts by weight of raw materials: white mustard 8 parts, 15 parts of Ziping, 25 parts of Alternanthera, 40 parts of Artemisia nigra, 35 parts of Turnip, 3 parts of Wangjiangnan, 3 parts of Coptis, 8 parts of Eucommia, 4 parts of Ligustrum lucidum...

Abstract
The invention discloses a high-efficient laying hen breeding method, and in particular relates to a technical scheme of breeding targets, nutritional levels and key control points of different breeding stages in a whole laying hen breeding process. The method is characterized by regarding 0 to 15 day-age as a mouth opening stage; (2) regarding 16 to 70-day-age as a brood stage; (3) regarding 71 to 112-day-age as a growing stage; (4) regarding 113 to 220-day-age as a pre-production stage; (5) regarding 221 to 580-day-age as an egg laying peak stage. According to the long-term practice and experience of the applicant, the whole laying hen breeding process is reasonably divided into at least five stages, wherein aiming at the growing features and required nutrition features of laying hens in each stage, the high-efficient laying hen breeding method disclosed by the invention designs reasonable nutritional requirements and stipulates operation key points of each stage; the breeding benefits are improved.
Description
Technical field [0001] The invention relates to the technical field of chicken and poultry breeding, in particular to a method for breeding laying hens. Background technique [0002] At present, there are many kinds of breeding methods and breeding modes of laying hens, but they are all unable to meet the needs of my country’s current economic development. Although the laying hen breeding industry has developed towards scale and standardization in the past 30 years, the scale and technology of laying hen breeding in my country It is gradually in line with international standards, but there is still a huge gap (Table 1). In order to improve breeding efficiency and narrow the gap with the international advanced level, it is urgent to promote an efficient layer breeding model. This requires us to constantly explore and adjust the breeding mode or method in the process of laying hen breeding. [0003] Table 1: Differences between my country's laying hen farming and foreign countries (b...
