Abstract
The invention relates to a hatching method for improving the survival rate of ducklings. The process from the shell quitting of the first duckling to the shell quitting of all ducklings is called as a hatching window. Through knowing the hatching window, the remaining time of the ducklings in a hatching device can be reduced, and meanwhile, duck groups with higher uniformity can be favorably fed in duck fields. The hatching method adopts the following technical scheme that: the temperature and the humidity of the hatching device are gradually reduced in 6 to 8 hours before the duckling picking, and the hatching temperature is regulated to 36.2DEG C in the sixth hour before the duckling picking according to the condition of the hatching window period; and the hatching temperature is reduced by 0.2 DEG C per hour, the temperature reduction is continuously carried out for 3 to 4 hours, the lowest temperature is 35.2 DEG C, and meanwhile, the humidity is reduced according to the week age of hatching eggs. The hatching method has the following beneficial effects that one one hand the heat stress caused by long-time high temperature of the ducklings in the hatching device is reduced, on the other hand, the high-temperature duckling dehydration can be reduced, and more importantly, the temperature difference between the temperature inside the hatching device and the environment temperature can be gradually reduced, so the cold stress caused in the process of moving the ducklings from the hatching fields to duck raisers is reduced.
Description
Technical field:
The present invention relates to a kind of cultural method, relate in particular to a kind of hatching method that increases the young survival rate of duck.
Background technology:
During hatching later stage hatching, keep the constant temperature hatching under the regular situation, especially after the part duckling early goes out shell, in the hatching device, cause duckling heat stress and dehydration easily.The quality of duckling only can reduce after the hatching, can not improve.The duckling survival rate raising 1.5% that the hatching Room of 40 incubators is produced will be produced 4980000 pounds hair duck more.The hair duck is worth 498000 dollars.This does not also comprise the raising of feed conversion rate and daily gain.
Go out shell from first young bird and all go out shell to all ducklings, this process weighs up young window.You can reduce the time that duckling stops in the hatching device through understanding the hatching window, help the duck field to raise out simultaneously and have the more duck crowd of high evenness.
Summary of the invention:
Goal of the invention: for provide can reduce stress and cold stress, prevent duckling dehydration, increase a kind of hatching method that increases the young survival rate of duck of duckling survival rate.
In order to reach as above purpose, the present invention takes following technical scheme: progressively reduced hatching actuator temperature and humidity in 6-8 hour before young picking up.
The further technical scheme of the present invention is: picking up young preceding the 6th hour, adjustment hatching temperature is 36.2 ℃; Per hour reduce by 0.2 ℃ of hatching temperature, continuous three-four hours, minimum to 35.2 ℃, simultaneously according to reducing humidity kind of an age in egg week.
The further technical scheme of the present invention is: picking up young preceding the 6th hour, adjustment hatching temperature is 36.2 ℃; Picking up young preceding the 5th hour, adjustment hatching temperature is 36.0 ℃, reduces humidity 1% simultaneously; Picking up young preceding the 4th hour, adjustment hatching temperature is 35.8 ℃; Picking up young preceding the 3rd hour, adjustment hatching temperature is 35.6 ℃, downward modulation humidity 1%; Picking up young preceding the 2nd hour, adjustment hatching temperature is 35.4 ℃; Reduce humidity 1% simultaneously, until hatching.
Adopt as above the present invention of technical scheme, have following beneficial effect: reduce the duckling heat stress that long-time high temperature causes in the hatching device; Can reduce the dehydration of high temperature duckling on the other hand; Most important one side is to shorten the temperature difference of interior temperature of hatching device and environmental temperature gradually, thereby reduces the duckling cold stress that this process causes to foster duck family from the hatchery.
Embodiment:
Describe in the face of embodiments of the invention down, embodiment is not construed as limiting the invention:
The present invention takes following technical scheme: progressively reduced hatching actuator temperature and humidity in 6-8 hour before young picking up.
The further technical scheme of the present invention is: picking up young preceding the 6th hour, adjustment hatching temperature is 36.2 ℃; Per hour reduce by 0.2 ℃ of hatching temperature, continuous three-four hours, minimum to 35.2 ℃, simultaneously according to reducing humidity kind of an age in egg week.
The further technical scheme of the present invention is: picking up young preceding the 6th hour, adjustment hatching temperature is 36.2 ℃; Picking up young preceding the 5th hour, adjustment hatching temperature is 36.0 ℃, reduces humidity 1% simultaneously; Picking up young preceding the 4th hour, adjustment hatching temperature is 35.8 ℃; Picking up young preceding the 3rd hour, adjustment hatching temperature is 35.6 ℃, downward modulation humidity 1%; Picking up young preceding the 2nd hour, adjustment hatching temperature is 35.4 ℃; Reduce humidity 1% simultaneously, until hatching.
According to hatching window situation, relevant performance can have suitable change.
Normal hatching device is allowable temperature, humidity adjustment all, if can not tunable incubator producer.
More than show and described basic principle of the present invention, principal character and advantage of the present invention.The technical staff of the industry should understand; The present invention is not restricted to the described embodiments; That describes in the foregoing description and the specification just explains principle of the present invention; The present invention also has various changes and modifications under the prerequisite that does not break away from spirit and scope of the invention, and these variations and improvement all fall in the scope of the invention that requires protection.The present invention requires protection domain to be defined by appending claims and equivalent thereof.
