Abstract
The invention belongs to the field of poultry farming and relates to an off-season variable temperate hatching technique for eggs of southern Landaise grey geese. The technique is designed by simulating hatching behaviors and egg temperature changes during natural hatching in off-season egg laying of the southern Landaise grey geese; the whole egg hatching process is finely divided into 14 phases; temperature changes in the hatching process are effectively controlled, so that hatching rate of fertilized eggs of the southern Landaise grey geese reaches more than 98%, health rate of young geese reaches more than 99%, and average birth weight ratio is increased by more than 20%.
Description
Technical field
The invention belongs to poultry farming field, specifically, is the hatching technique of a kind of poultry, particularly the anti-season Hatchability technology of the bright moral ash in a kind of south swan egg.
Background technology
Bright moral goose claims again southwestern grey goose, originates in the French west and south by the Lang De province of Bay of Biscay.In south, it is generally to finish in April of annual October to next year that bright moral goose is laid eggs.In order to address this problem, people have invented anti-season and have laid eggs, and annual 5-8 month kind goose is laid eggs, and prior art has solved the problem that anti-season is laid eggs.This anti-season lay eggs is on the occasion of southern high temperature and plum rain season, if adopt the hatching technique of normally laying eggs season, as Constant temperature hatch, the hatching process at whole egg keeps a kind of stationary temperature exactly, be generally 37.8 ℃, the incubation rate of fertilized egg is less than 60%.Another kind is Hatchability technology, be exactly in the hatching process of whole egg, be divided into several processes, the incubation temperature of different process eggs is different, the incubation temperature of same process egg is identical, it is generally the first principle of high, rear low, intermediate equilibria, general requirement is within 1-12 days, to be 37.8 ~ 38 ℃, within 13-28 days, be 37.5 ~ 37.8 ℃, 29 days to hatching be 37.0 ~ 37.3 ℃, the middle water spray that adopts is lowered the temperature to egg, this hatching technique, fertilization and hatching rate incubation rate is 80% left and right, and strong young rate is 75% left and right.
Summary of the invention
It is not high that the present invention can solve southern bright moral ash swan egg anti-season hatching fertilization and hatching rate incubation rate, the strong low problem of young rate.
The present invention is according to south bright moral ash swan natural conditions, when close goose hatching, the anti-season Hatchability technology of the grey swan in a kind of south that eggshell surface temperature variations designs, object is during by the anti-season hatching of bright moral ash swan egg, and the incubation rate of fertilized egg and strong young rate reach more than 95%.
The present invention is achieved through the following technical solutions.
An anti-season Hatchability technology for bright moral ash swan egg, is characterized in that:
The temperature of whole hatching process is adjusted to:
By the preheating temperature to 28 in hatch machine ℃;
At the 0-12 hour of hatching, temperature during hatching is slowly elevated to 38.4 ℃ from 28 ℃;
At the 13-144 hour of hatching, temperature during hatching is 38.4 ℃;
At the 145-150 hour of hatching, the temperature during from hatching is slowly reduced to 31.8 ℃;
At the 151-156 hour of hatching, temperature during hatching is 31.8 ℃;
At the 157-162 hour of hatching, the temperature during from hatching is slowly warmed up to 38.2 ℃ from 31.8 ℃;
At the 163-264 hour of hatching, temperature during hatching is 38.2 ℃;
At the 265-270 hour of hatching, the temperature during from hatching is slowly reduced to 31.6 ℃;
At the 271-276 hour of hatching, temperature during hatching is 31.6 ℃;
At the 277-282 hour of hatching, the temperature during from hatching is slowly elevated to 38 ℃ from 31.6 ℃;
At the 283-420 hour of hatching, temperature during hatching is 38 ℃;
At the 421-426 hour of hatching, temperature during hatching is reduced to 31.4 ℃;
At the 427-432 hour of hatching, temperature during hatching is 31.4 ℃;
At the 433-438 hour of hatching, the temperature during from hatching is slowly elevated to 37.8 ℃ from 31.4 ℃;
At the 439-480 hour of hatching, temperature during hatching is 37.8 ℃;
At the 481-486 hour of hatching, temperature during hatching is slowly reduced to 30.4 ℃;
At the 487-492 hour of hatching, temperature during hatching is 30.4 ℃;
At the 493-498 hour of hatching, temperature during hatching is slowly elevated to 37.4 ℃ from 30.4 ℃;
At the 499-564 hour of hatching, temperature during hatching is 37.4 ℃
At the 565-570 hour of hatching, temperature during hatching is slowly reduced to 29.8 ℃;
At the 571-576 hour of hatching, temperature during hatching is 29.8 ℃;
At the 577-582 hour of hatching, the temperature during from hatching is elevated to 37.2 ℃ from 29.8 ℃;
At the 583-648 hour of hatching, temperature during hatching is 37.2 ℃;
At the 649-654 hour of hatching, temperature during hatching is slowly reduced to 28 ℃;
At the 655-660 hour of hatching, temperature during hatching is 28 ℃;
At the 661-666 hour of hatching, the temperature during from hatching is slowly elevated to 36.8 ℃ from 28 ℃;
At the 666-744 hour of hatching, temperature during hatching is 36.8 ℃.
Described temperature slowly raises or reduces, and is that the heating element of being controlled in hatch machine by the single-chip microcomputer in hatch machine is realized.
The present invention is while naturally hatching according to the bright moral of inventor's long-term observation ash swan field egg, by recording the Hatchability technology of a kind of bright moral ash swan that the southern bright moral ash incubation behavior of swan and the variations in temperature of egg design, the hatching process of whole egg is become more meticulous and is subdivided into 14 stages, by the variations in temperature of effective control hatching process, provide a kind of bright moral ash swan to hatch new technology in anti-season.
Traditional spray cooling technology, the eggshell of not considering southern grey swan is thicker, be easy to cause cooling too fast, too fast in the part cooling near eggshell, and middle embryo part cannot be lowered the temperature at short notice, too high temperature has suppressed embryo's growth, even there is the situation that high temperature is burnt to death, incubation rate is reduced.The inventor, according to the cooling naturally under the grey swan natural conditions in south, has adopted falling temperature technique slowly, makes the various piece uniform decrease in temperature of egg, and the speed of cooling is slow, and the growth of the embryo in it can be affected.
Utilize the present invention to carry out the hatching of bright moral ash swan egg, hatchability of fertile eggs reaches more than 98%, and the healthy rate of young bird reaches more than 99%, and average birth weight improves more than 20% than other hatching techniques.
