Industry is quickly grown.However, that there are natural breed success rates is low, artificial breeding hatching technique is still immature etc. asks for black Swan egg hatching
Topic, further hinders its development.Thus, black Swan ovum artificial incubation technique is studied, improving hatching rate is black Swan cultivation
The key factor of development.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of black Swan hatching of breeding eggs sides easy to operate, hatching rate is high
Method.
In order to solve the above technical problem, the present invention provides a kind of black Swan hatching of breeding eggs methods, comprising the following steps:
1), the cleaning and sterilizing of hatching egg:
First hatching egg is cleaned up；
The water for adding 50 ± 5 volumes times in 5% (volume %) bromogeramine stoste, is configured to bromogeramine dilution；
Bromogeramine dilution is heated to 43~50 DEG C, be put into the hatching egg after cleaning up impregnate 3~5 minutes (thus
Realize hatching egg disinfection), then hatching egg is pulled out and is dried (until no longer dripping), hatching egg after cleaning and sterilizing is obtained；
2), hatch:
1., control hatch indoor temperature and relative humidity:
Hatching egg after the resulting cleaning and sterilizing of step 1) is put into hatching house:
1st~the (12 ± 1) day is hatching early period, and it is 38~38.5 DEG C that indoor temperature is hatched in control, and relative humidity is
55%~59%；
Hatching terminates the~the (19 ± 1) day as hatching mid-term early period, and it is 37.5~37.8 DEG C that indoor temperature is hatched in control,
Relative humidity is 59~60%；
Hatching mid-term terminates the~the (27 ± 1) day as the hatching later period, and it is 37.3~37.8 DEG C that indoor temperature is hatched in control,
Relative humidity is (65 ± 1) %；
The hatching later period terminates~and to go out shell be rule phase (young goose goes out shell and is generally the 39th day or so) for young goose, it controls in hatching house
Temperature be 36.8~37.1 DEG C, relative humidity be 70%~75%；
2., turning egg(s):
From hatching is started up to the 35th ± 1 day, every 2 ± 0.2 hours turning egg(s)s 1 time, each turning egg(s) angle is 90~180 °
(note: hereafter~rule phase terminates without turning egg(s))；
3., cool egg:
25th ± 1 day to the 31st ± 1 day is cool egg early period (once a day), cool egg early period are as follows: afternoon 1 point daily~
, hatching egg taken out to out of hatching house and is put into 20~23 DEG C of cooling chamber (cooling chamber generally requires the ventilation for keeping conventional at 2 points
State), when hatching egg blunt end temperature is 2 ± 0.5 DEG C higher than the room temperature of cooling chamber, terminating cool egg, (the cool egg time is about 10 ± 1 points
Clock)；
Early period, cool egg terminated until when young goose goes out shell as later period cool egg (once a day), the later period cool egg are as follows: every
It afternoon 1 point~2 points, hatching egg is taken out out of hatching house and is put into (cooling chamber generally requires guarantor in 20~23 DEG C of cooling chamber
Hold ventilation), and hatching egg is sprayed with 20~25 DEG C of warm water, the warm water fountain height of each hatching egg is 2~4ml；Work as hatching egg
When blunt end temperature is 2 ± 0.5 DEG C higher than the room temperature of cooling chamber, terminate cool egg.
Note: the time of later period cool egg is generally no more than 30 minutes.
Improvement as black Swan hatching of breeding eggs method of the invention:
It carries out when hatching starting early period according to egg, to reject infertile egg (that is, only carrying out hatching processing to fertile egg)；
Hatch early period carry out to half the time, hatching early period at the end of, hatching mid-term at the end of, hatching the later period at the end of
It is respectively primary according to egg, to reject dead smart egg.
Note:
The criterion of infertile egg is (this is well known routine techniques): using candler according to the sharp end of egg, if hair in hatching egg
It is bright, flaxen shadow is only seen, infertile egg is determined as；
The criterion of dead essence egg is (this is well known routine techniques):
In hatching early period, the sharp end of egg is shone using candler, it can be seen that eyespot egg face accounts for 4/5ths of entire egg face, color
Scarlet pool is normal fertile egg, but in egg it is muddy, there is blood circle, clot be dead essence egg；
In hatching mid-term, with candler against the sharp end of hatching egg；It is normally to be fertilized that blood vessel is gathered in the sharp end part of egg
Egg, but gas chamber is relatively fuzzyyer, and it is dead smart egg that black bulk, which is presented, in embryo；
It can't see shinny part with candler against the sharp end of hatching egg in the hatching later period, seen that blunt end is close to gas
There is the red tape of 1 centimetre of wide left and right in room, is normal fertile egg；It is then dead smart egg but if band is not red.
As black Swan hatching of breeding eggs further improvements in methods of the invention:
In the hatching process of the step 2), need to guarantee that hatching chamber ventilated is smooth, the entire hatching chamber body of replacement per hour
The air of product 70 ± 10%.
Note: the air of ventilation is without disinfection, natural air.
As black Swan hatching of breeding eggs further improvements in methods of the invention:
While hatching egg, which is moved into cooling chamber, to be cooled down, taken a breath to hatching house (fast using tools such as exhaust fans
The air of speed replacement hatching house), it is all replaced so that it is guaranteed that hatching indoor air；And the hatching egg after ensuring to cool down needs to return
When hatching house, the temperature and humidity of hatching house reaches the temperature and humidity of setting.
As black Swan hatching of breeding eggs further improvements in methods of the invention: the hatching house is incubator or egg nest.
As black Swan hatching of breeding eggs further improvements in methods of the invention, weighing is also provided with during hatching:
Timing weighs to hatching egg and records and (weigh hatching egg weight with the balance that sensibility reciprocal is 0.1g) during hatching, weighs
Time be the morning 9 when~10 when；Hatching egg same day weight-loss ratio=(embryo egg the previous day, embryo egg weight-same day weight)/the previous day embryo egg weight *
100%；
When hatching egg same day weight-loss ratio is 0.55%~0.70%, determine that hatching of breeding eggs belongs to normal condition；
As hatching egg same day weight-loss ratio > 0.70% or < 0.55%, determines that hatching of breeding eggs belongs to and go wrong, to the hatching egg
Make rejecting processing.
As black Swan hatching of breeding eggs further improvements in methods of the invention:
When hatching egg same day weight-loss ratio is 0.60%~0.65%, without adjusting the relatively wet of incubation period locating for hatching house
Degree；
As 0.55%≤same day weight-loss ratio < 0.60%, when above-mentioned hatching egg is returned in hatching house, hatch indoor wet
Degree its locating incubation period of selection corresponds to the lower limit value of humidity, specifically:
Hatch early period, relative humidity is 55%~56%；

During hatching of breeding eggs of the invention, based on Hatchability, in the case where guaranteeing set temperature, humidity condition, lead to
Wind wants smooth, and the front is high and the back is low gradually reduces temperature, low early and high after to step up humidity.
Fertilization and embryonic development situation, difference infertile egg, fertile egg, dead smart egg, to pick should be examined during hatching according to egg
Except infertile egg and dead smart egg, hatch qualified hatching egg.
Due to goose respiration enhancing young in hatching later period hatching egg, heat production increases, so needing to carry out artificial cool egg, benefit
It is wet；It is carried out artificial hypothermia (mending wet) that is, it needs to which hatching egg to be placed in cooling chamber within the set time, after cooling (mending wet),
Hatching egg is returned in hatching house again.Water spray when later period cool egg, is taking away hatching egg waste heat using small water droplet natural evaporation
While also act as supplement hatching of breeding eggs humidity effect.Cool egg purpose is first is that distribute the extra heat of hatching egg in time, second is that more
Change the ozone in hatching egg.Cool egg process can not excessive cool egg, young goose development otherwise will occur in hatching egg and slow down, stop
Phenomena such as developing, be even dead.
Except when hatching egg is moved into cooling chamber when being cooled down, needs to carry out strength ventilation to hatching house, in addition to this
In other times, hatches indoor air and slowly circulate according to the ventilation volume of setting with outside air, without acutely replacing, with
Guarantee hatching process in incubation temperature, humidity it is relatively stable.
