Abstract
The invention discloses an egg cooling method used in a duck egg hatching process. In the duck egg hatching process, duck hatching eggs with an incubation period of 10-15 days are cooled; cooling is carried out for once every 24-48 hours in the hatching process and lasts for 25-70 minutes every time. According to the egg cooling method, the ventilation of embryo eggs can be improved in the egg hatching process, the embryo eggs can be ventilated effectively, and excessive heat generated by the embryo eggs in the egg hatching process can be emitted; the method is combined with spray disinfection, so that the embryo humidity is improved.
Description
technical field:the present invention relates to the cool egg method in a hatching of breeding eggs process, particularly a kind of cool egg method in duck hatching of breeding eggs process.
background technology:along with the expansion of poultry chick hatching scale, the management of hatching details shows its importance day by day.The particularly expansion of newly-hatched duckling hatching scale, hatching flatly progressively improves, and newly-hatched duckling hatches the height of level and incubation rate, directly affects duck raiser's economic well-being of workers and staff.
Current Climate Anomalies, climatic environment condition warms day by day, the south summer high temperature high humidity weather time is longer, how to improve the hatching yield of duck's egg, improve duck farmer raiser's economic benefit, in the hatching process of duck kind egg, all the important measures that can improve duck's egg incubation rate to the improvement of the links in hatching process with controlling, as increased the control of cool egg link in the hatching process of duck kind egg, how in the time of the hatching of duck's egg, carrying out cool egg processing is the important means that can improve duck hatching of breeding eggs rate.
summary of the invention:the invention provides a kind of cool egg method in duck hatching of breeding eggs process, the air capacity of soils that it can improve duck kind egg embryo egg in hatching process, is conducive to the ventilation of embryo egg, distributes the waste heat that in duck hatching of breeding eggs process, embryo egg produces, in conjunction with spray sterilization, also can improve embryo's humidity.
Cool egg method in a kind of duck hatching of breeding eggs of the present invention process, first duck kind egg is cleaned, sterilizes and hatch, it is in hatching process, the duck kind egg that is 10-15 week sky to brooding time carries out cool egg processing, control every hatching 24-48 hour, once, each cool egg time is 25-70 minute to cool egg.
Cool egg processing of the present invention is with disinfectant, the duck kind egg surface of hatching to be sprayed and drenched cooling processing.
Cool egg method in a kind of duck hatching of breeding eggs process of the present invention, its control is 35.5 DEG C-36.5 DEG C through the duck kind egg temperature of cool egg processing.
Described in control of the present invention, the temperature of the disinfectant of cool egg processing use is 30-35 DEG C.
The present invention is in to the hatching process of duck kind egg, duck kind egg to hatching carries out cool egg processing, adopt disinfectant to the mode of duck kind egg fountain, the duck kind egg cooling in hatching to be processed, disinfectant used can be by commercially available acquisition, or autogamy, as clorox in hypochlorite etc., it can significantly improve the air capacity of soils of duck kind egg embryo egg in hatching process, be conducive to the ventilation of embryo egg, distribute the waste heat that in duck hatching of breeding eggs process, embryo egg produces, adopt spray sterilizing method to the duck kind egg cooling in hatching simultaneously, also can improve embryo's humidity.The incubation rate that can improve compared with the existing methods duck kind egg reaches 1-1.5 percentage point, improves hatching benefit and reaches more than 1.5%.
embodiment:below in conjunction with the concrete embodiment of implementing, the present invention is described in further detail.
In to the hatching process of duck kind egg, can adopt existing hatching m and hatching apparatus, a common hatching house, 10000 pieces of above duck kind eggs of a batch of hatching.After first the duck kind egg water of intending hatching being cleaned, using disinfectant disinfection, is clean and sterilize and carry out simultaneously at present.To duck hatching of breeding eggs 10-15 Zhou Tianhou, week age was in 7 days; Start to carry out cool egg processing, in the time of cool egg, control to hatch 24-48 hour, carry out cool egg once, can the cool egg time of interval in the time that outside air temperature is lower longer, generally can be more than 48 hours cool egg below 60 hours once.Each cool egg time also should be controlled at 25-70 minute, and the embryo egg temperature of the general duck kind egg taking hatching, as yardstick, is controlled at 35.5 DEG C-36.5 DEG C, is preferably controlled at 36 DEG C-36.5 DEG C and is advisable.When manual detection, use eyelid thermometric, not dazzling being advisable of sensation gentleness.
When concrete enforcement, the embryo egg in hatching process is implemented to the cooling egg time: in 1 year, the spring, summer, autumn and winter all can be implemented cooling egg.The best duration of the cool egg of embryo egg: summer, more than 1 hour be to be all controlled at about 30 minutes in spring, autumn, winter all the other seasons.Embryo egg is implemented cool egg optimum efficiency controlling: taking embryo egg temperature as yardstick, use eyelid thermometric, not dazzling being advisable of sensation gentleness, is preferably advisable at 36 DEG C-36.5 DEG C.
In hatching process, along with the increase in age of hatching duck kind egg embryo, the metabolic self-produced thermal gauge of embryo egg self is restrained, and adds to the unfavorable factor of environment temperature, humidity, particularly causes during the broiling summer incubator box class overtemperature serious, needs cool egg; General 10 weeks summers, sky carried out cool egg, 13-15 week day in other seasons; In cool egg process, disinfecting drug is prepared certain concentration by operation instructions, and water temperature is controlled at 30-35 degree Celsius, and the pull-out even dispersing dry embryo egg of egg car surface, reaches the state of drenching; The cooling egg time in summer is about 1 hour, about other 30 minutes seasons, with the microcephaly that feels embryo egg temperature with temperature cool being advisable not; When summer, room temperature was higher, room temperature is greater than 33 DEG C, every day cool egg once; General two days of other seasons once.
In the time implementing, arrange specialty hatching operative employee, be responsible for cool egg matters specially.And assign key single-minded supervision, record, the result of being responsible for cool egg operating process to gather.Through constantly test, actual result situation: carry out while adopting the inventive method to duck hatching of breeding eggs after cool egg processing compared with the conventional method, can improving incubation rate 1-1.5 percentage point, improve hatching benefit 1.5%, produce good economic benefit.
Specifically be compared as follows: do not adopt cool hatching mode to comprise 737,738,739 3 batches: 737-742 represents batch (lower same), 737 batches enter to incubate 12096 pieces, 738 batches enter to incubate 12086 pieces, and 739 batches enter to incubate 12066 pieces three batches and enter to incubate chickling-surviving rate and be respectively 83.0 ﹪, 83.5 ﹪, 83.6 ﹪.And adopt the present invention cool egg method to comprise 740,741,742 3 batches: 740 batches enter to incubate 12096 pieces, and 741 batches enter to incubate 12086 pieces, and 742 batches enter to incubate 12066 pieces, these three batches and enter to incubate chickling-surviving rate and be respectively; 84.5 ﹪, 84.7 ﹪, 85.1 ﹪.Explanation from the above adopts after above-mentioned cooling egg method, can improve incubation rate 1-1.5 percentage point, improves hatching benefit 1.5%.
