Problems solved by technology

Uni Z. et al. (2005) injected a mixed nutrient solution of maltose, sucrose, dextran and other polysaccharides and β-hydroxy-β-methylbutyrate, although it could also increase liver glycogen in chicken embryo liver to a certain extent. content, but the formula of its nutrient solution is complex, and it is difficult to popularize and apply. In theory, the digestive tract of embryonic broilers is not fully developed, and it cannot secrete enough digestive enzymes such as maltase to hydrolyze polysaccharides into monosaccharides for absorption. Therefore, we believe that the results of the study are quite controversial

Embodiment 1

[0019] The preparation of embodiment 1 nutrient solution

[0020] Weigh 8.5 g of sodium chloride, dissolve it in distilled water, and adjust the volume to 1000 mL with a volumetric flask to prepare 0.85% normal saline. Weigh 3.125g of glucose and 0.75g of creatine monohydrate (CMH), fully dissolve them in 50mL of 0.85% normal saline respectively, and prepare the injection nutrition solution containing 62.5mg glucose per milliliter and the injection nutrition solution containing 15mg CMH per milliliter Then weigh 3.125g of glucose and 0.75g of CMH, fully dissolve in 50mL of 0.85% normal saline, and prepare a nutrient solution for injection containing 62.5mg of glucose and 15mg of CMH per milliliter. All the prepared nutrient solutions for injection and the remaining physiological saline were autoclaved at 121°C for 15 minutes, cooled and stored in sterile sealed bags for future use. Heat in a constant temperature water bath at 37.5°C before use.

Embodiment 2

[0021] Implementation of embodiment 2 embryo egg injection technology

[0022] 1) Chicken embryo incubation conditions

[0023] Disinfection of the incubator: It is recommended to use the HXC-5 microcomputer automatic incubation controller produced by Nanjing Hengxin Incubation Equipment Co., Ltd., wash it with water before use, and then spray 1% concentration of bromine disinfectant on the inner wall of the incubator or add 50% of the original solution of bromine to the incubator. Finally, wipe all places, including every corner, with a rag dipped in disinfectant, and let it dry for later use.

[0024] 650 Arbor Acres (AA) broiler commercial replacement eggs (purchased from Jiangsu Jinghai Poultry Industry Group Co., Ltd., egg weight range 58-62g, average egg weight 60.65g), check the eggs before hatching, remove broken eggs, For cracked eggs and sand-shell eggs, use 1% bromogeramine for qualified eggs, spray on the surface of the eggs, and let it dry.

[0025] The steriliz...

Embodiment 3

[0046] Embodiment 3 broiler early growth performance evaluation

[0047] After the broilers hatched, 48 chicks were selected from the broilers in Group I, Group II and Group III respectively and assigned to 6 replicates, with 8 chickens in each replicate. The ground is raised flat, with natural light and artificial supplementary light, the light intensity is 30lx, and the light is 24 hours a day for 1-7 days. The feeding period was 7 days in total. The feeding management is carried out according to the "AA Broiler Feeding and Management Manual", with free access to food and water, and the broiler chickens are fed commercial pellet diets. The test was stopped at the end of the 7th day of age, and the production performance indicators such as feed intake, body weight and feed-to-weight ratio of broilers in each treatment group were calculated in Table 4.

Abstract

The invention discloses a hatching method for increasing energy reserve of commercial generation hatching eggs of white feather broilers. In a later hatching stage of the commercial generation hatching eggs of the white feather broilers, 0.4 mL of sterilizing injection nutritive liquid is injected to embryo eggs, then hatching continues to be carried out under original hatching conditions for 21 days, and then the broilers are hatched, wherein each mL of the sterilizing injection nutritive liquid is prepared from 60-62.5 mg glucose and 10-15 mg creatine monohydrate. Compared with traditional hatching, by means of the technology, the energy matter reserve mainly including hepatic glycogen in the liver and the energy matter reserve mainly including creatine and phosphocreatine in the chest muscle in the later broiler embryo hatching stage are significantly increased and can last to the time when the broilers are one day old, the growing speed of the broilers in the early hatching-out period can be increased, and the breeding production efficiency of the broilers can be improved. The hatching method has the advantages of being low in cost, easy and convenient to implement, practical, high in operability and the like, and is suitable for being applied to poultry hatching production.

Description

technical field [0001] The invention belongs to the technical field of hatching and feeding of poultry in animal husbandry, and relates to a hatching method for increasing the energy reserve of white-feathered broiler eggs. Background technique [0002] Broiler chickens are oviparous animals, and their embryonic development is separated from the mother and carried out in a closed environment. Under conventional incubation conditions, the energy and nutrients required for the development of broiler embryos during the 21-day incubation period are only provided by the nutrients stored in the eggs. Studies have shown that in the first week of incubation, the energy required for chicken embryo development is mainly provided by 1% carbohydrates in the embryo egg (Moran Jr.E.T., Poultry Science, 2007, 86(5):1043-1049); The fatty acid (accounting for about 33% of the fresh weight of egg yolk) is oxidized to become the main energy supply mode (Noble R.C. and Cocchi M.Progressin Lipi...
