Abstract
The invention discloses an artificial variable temperature hatching method for American partridges, belonging to the field of artificial hatching of poultry. The artificial hatching method comprises the following steps of: sterilizing hatching eggs and accommodating the hatching eggs in artificial hatching equipment for hatching at the temperature of 37.5-37.8DEG C and relative humidity of 60-65 percent; carrying out egg candling for the first time after the hatching is carried out for 6-7 days; carrying out nesting after 21-22 days at the temperature of 37.4-37.7DEG C and the relative humidity of 65-70 percent; and breaking hull and emerging after 2-3 days. In the artificial variable temperature hatching method disclosed by the invention, according to the biological characteristics of hatching egg development, by adjusting the temperature of external environment and controlling the ventilation flow and air humidity, the hatching eggs can be ensured to be better developed so as to improve the hatching rate and healthy young partridge rate. Meanwhile, reasonable sterilizing measures are adopted to ensure that the hatching eggs are prevented from being infected by bacterial at the subsequent hatching phase.
Description
Technical field
The present invention relates to poultry artificial incubation field, relate in particular to the artificial alternating temperature hatching m of a kind of U.S. francolin.
Background technology
U.S. francolin be the domestication of wild chukar and meat egg dual-purpose chukar kind, long 27～37 centimetres of body, body weight 440～580 grams; Its protein content is 30.1%, and is higher by 10.6% than chicken, and fat content is 3.6%; Lower by 4.2% than chicken, content of fatty acid is 64%, is unsaturated fatty acid.Especially contain unexistent ox sulphur in other bird body, taurine is of value to children's intelligence development, has very high medical value.U.S. francolin grows soon, and breeding cycle is short, and dressing percentage is high, and meat flavour is delicious, has received increasing consumer and has paid close attention to.
U.S. francolin went out shell in general 23～25 days; The francolin artificial incubation technological borrowing of the existing U.S. artificial incubation technology of egg; Adopt automatic incubator box; Adequate ventilation is provided; Carry out egg-turning under the situation with good conditionsi, but hatching most important incubation temperature of influence and humidity are not obtained the enough attention of people.Most of producer is constant temperature hatchings between 37～38 ℃ when artificial incubation U.S. francolin, and guarantee that enough ventilations and more moistening environment, this method have limited the incubation rate of planting egg, and it is healthy to influence young bird.
Summary of the invention
Goal of the invention: the purpose of this invention is to provide the artificial alternating temperature hatching m of a kind of U.S. francolin, be used to produce the U.S. francolin of high hatchability and the young rate of Jiang Gao.
Technical scheme: for realizing above-mentioned purpose, the artificial incubation method of a kind of U.S. of the present invention francolin comprises: will plant the egg sterilization, and place artificial incubation equipment to hatch; The temperature in said hatching stage is 37.5～37.8 ℃, and relative moisture is 60～65%, carries out the first time according to egg, and arrives the hatching stage through 21～22 days in the 6th～7 day of hatching; The temperature in said hatching stage is 37.4～37.7 ℃, and relative moisture is 65～70%; Go out clearly through broken shell in 2～3 days again.
The hatching stage finishes the back, carries out the second time when hatching stage begins according to egg.Twice according to sorting out clear egg and addled egg in the egg process.
Said kind of egg sterilization adopts 1 cubic metre of volume with 28 milliliters of formalin, potassium permanganate 14 grams, fumigates and discharges gas after 1～2 hour.Can place 15～20 ℃ kind egg storeroom after planting the egg sterilization.Kind of egg shelf life is preferably less than 4 days, guaranteeing incubation rate, and plants egg and will guarantee not have fecal pollution, meets kind of an egg specification.
The present invention adopts alternating temperature technology hatching U.S. francolin kind egg, and the temperature in said hatching stage is reduced to 37.5 ℃ gradually from 37.8 ℃; The temperature in said hatching stage rises to 37.7 ℃ gradually from 37.4 ℃.Specifically, incubation temperature was 37.8 ℃ in the 1st～6 day, and incubation temperature dropped to 37.5 ℃ in the 7th～21 day, and the 22nd～24 day hatching temperature was from 37.4 ℃ of 27.7 ℃ of rising to the 24th day of the 22nd day.
Beneficial effect: the artificial alternating temperature hatching m of a kind of U.S. of the present invention francolin; According to kind of the biological property of egg growth; Through adjustment external environment temperature; Control ventilation flow rate and air humidity; Guaranteeing to plant an egg grows better; To improve incubation rate and strong young rate, take scientific and reasonable disinfectant measure simultaneously, guarantee that kind of an egg is not subjected to bacterial infection in the follow-up hatching stage.
Embodiment
The artificial alternating temperature hatching m of a kind of U.S. of the present invention francolin comprises:
Choose satisfactory kind of egg, no fecal pollution is planted the egg sterilization and is adopted 1 cubic metre of volume with 28 milliliters of formalin, potassium permanganate 14 grams, stifling 1～2 hour.Can place 15～20 ℃ kind egg storeroom after planting the egg sterilization, shelf life is preferably less than 4 days.
To plant egg places artificial incubation equipment to hatch; The temperature in hatching stage is 37.5～37.8 ℃; Relative moisture is 60～65%; Carried out the first time according to egg in the 6th～7 day of hatching; Arrived the hatching stage through 21～22 days; Carry out the second time according to egg; Twice the temperature in hatching stage is 37.4～37.7 ℃ according to sorting out clear egg and addled egg in the egg process, and relative moisture is 65～70%; Go out clearly through broken shell in 2～3 days again.
Planting egg needs certain ventilation when hatching, if conditions permit can be carried out egg-turning.Planting egg temperature in hatching process changes: incubation temperature was 37.8 ℃ in the 1st～6 day, and incubation temperature dropped to 37.5 ℃ in the 7th～21 day, and by the 22nd day, the hatching temperature was 37.4 ℃, and temperature rises to 37.7 ℃ during by the 24th day.
Adopt this method to carry out artificial incubation, incubation rate is more than 89%, and going out dead young bird of shell and lopsided young bird does not almost have.Below prove through comparative trial.
Get identical four car U.S. francolin kind eggs, 2000 pieces of kind eggs of per car are through going into to incubate after 24 hours in storeroom refrigeration after identical the disinfecting.Experimental group is taked the alternating temperature hatching in the embodiment of the invention, and 3 groups of constant at a certain temperature hatchings of control group guarantee good ventilation; Egg-turning is 6～10 times round the clock; Till knowing the 16th day, calculate incubation rate and strong young rate during by the 24th day, experimental scheme and result are as shown in table 1:
The comparative test result that table 1 adopts artificial alternating temperature hatching and constant temperature to hatch
Can find out, adopt method provided by the invention can effectively improve incubation rate and strong young rate, thereby bring more multivalence value and profit for the producer.
The above only is a preferred implementation of the present invention; Be noted that for those skilled in the art; Under the prerequisite that does not break away from the principle of the invention, can also make some improvement and retouching, these improvement and retouching also should be considered as protection scope of the present invention.
