Embodiment 1

[0034] ——Preparation of Intraembryo Supplies of the Present Invention

[0035] Pyrroloquinoline quinone disodium (gifted by Shanghai Medical Life Science Research Center, produced by chemical synthesis) was heated and dissolved in sterile normal saline (0.85% NaCl solution) at 65°C at a concentration of 2mM in a light-proof environment, and then micro- Store in the dark after sterilizing the pore filter.

Embodiment 2

[0037] ——Injection method of pyrroloquinoline quinone for intra-embryo feeding (intragas injection)

[0038] The operation steps of the injection method of feeding pyrroloquinoline quinone are as follows: when broiler embryos are hatched on the 7th day of embryo incubation, move the hatched embryos to the operating table, use a pencil to quickly trace the outline of the air cells of the embryo eggs, and use 75% alcohol to infiltrate the egg. Wipe and disinfect the absorbent cotton ball near the injection point, drill a hole with a micro-drill at the top of the air chamber, inject 1ml with a needle length of 8mm continuous syringe and immediately seal it with paraffin. The whole process is completed within 15 minutes and the eggs are returned to the incubator to continue incubation.

Embodiment 3

[0040] ——Injection method of pyrroloquinoline quinone for intra-embryo feeding (amniotic injection)

[0041] On the 17.5th day of broiler embryo hatching, move the hatched embryo to the operating table, use an egg canister to illuminate the position of the embryo, determine the position of the amniotic cavity and use a pencil to draw a small circle at the position of the needle, and use a cotton ball soaked with 75% alcohol on the Wipe and disinfect near the injection point, drill a hole with a micro-driller at the needle insertion position, inject 1mL with a disposable syringe with a needle length of 15mm, and seal it with paraffin immediately. The whole process is completed within 15 minutes and the eggs are returned to the incubator Continue to hatch.

Abstract

The invention relates to a method for promoting growth of a broiler chicken through intra-embryonic provision of pyrro-quinoline quinone (PQQ) and application of pyrro-quinoline quinone. 1ml of disodium pyrro-quinoline quinone (PQQ.Na2) solution (with the concentration of 1.0-4.0mM) is injected into a chick embryo air sac in a seventh embryo development stage during incubation by adopting a continuous injector used for injecting vaccine, the effects of increasing hatch weight of the broiler chicken, increasing market weight of the broiler chicken by 110g and increasing brisket weight by 50g are realized, and feed efficiency in the whole stage is improved by more than 5%; besides, stimulation of the air sac injection on embryo development is small, hatchability is not influenced, operation is simple, and working efficiency is high, so that the air sac injection is applicable to being used in large-scale production, and economic benefit is considerable; and a method for scientifically and reasonably applying intra-embryonic pyyro-quinoline quinone (PQQ) provision has a potential application space in intensive poultry production and has great significance in the poultry industry of China.

Description

technical field [0001] The invention relates to an intraembryo nutrient supplement for promoting the growth of broiler chickens and an application thereof, which belongs to the technical field of early nutrition of poultry in animal husbandry. Background technique [0002] With the rapid development of social economy and continuous improvement of people's living standards, the demand for meat products has been increasing. In the past 30 years, the consumption of poultry meat in the world has risen steadily, which is related to the relatively cheap price and easier availability of poultry meat. The production of 1kg of poultry meat requires about 2kg of feed, while the production of 1kg of pork or beef and mutton requires 3.5-8kg of feed. The growth rate of modern meat poultry continues to accelerate, the production cycle is further shortened, and the proportion of the hatching period is relatively increased. For example, the hatching period of broiler chickens and ducks is c...
