Description
Technical Field
The invention belongs to the technical field of cultivation, and particularly relates to an anti-season breeding control method for northern variety geese.
Background
Because the production and breeding activities of geese are seasonal, in the north of China, the laying period of geese is 3 months to 7 months every year, and production is stopped after 7 months, so that goose eggs, seedlings and commodity geese of the geese cannot be supplied all year round, the goose sources are lacking in the heavy season when the supply is excessively concentrated and the goose sources are lacking in the light season, and the goose industry development is severely restricted.
Because the natural environmental conditions such as sunshine duration, environmental temperature and the like in northern areas of China are greatly different from those in the south, the prior technical scheme can not meet the requirement of the anti-season breeding performance of northern variety geese, how to effectively implement the control of the anti-season breeding of the breeding geese aiming at different areas and reduce the anti-season production cost of the breeding geese, and a feasible method needs to be explored according to local conditions.
The invention provides an ecological natural breeding technology, which can enable northern variety goose species to lay eggs in an out-of-season manner, relieve the phenomena of concentrated supply in a busy season and goose source shortage in a slack season, and further promote the development of goose industry.
Disclosure of Invention
Aiming at the defects of the prior art, the invention provides an anti-season breeding regulation and control method for northern variety geese, which can regulate the egg laying peak of the northern variety geese from 3 months to 7 months to the first 7 months to the end 10 months of each year, and realizes the balanced supply of northern meat goose goslings.
In order to realize the purpose of the invention, the invention adopts the following technical scheme:
a northern variety goose anti-season propagation control method comprises the following steps:
step one, prolonging illumination: the method for prolonging the illumination is used for transiting the normal physiological development state of the northern variety goose from the normal physiological development state to the physiological development state of the off-season goose in four seasons of the year to promote the off-season goose to lay eggs, the illumination control measures which are different in four seasons of spring, summer, autumn and winter are adopted for prolonging the illumination, a time gradient method is adopted for prolonging the illumination, and the method for prolonging the illumination comprises the following specific regulation and control steps:
(1) in winter, the illumination time is controlled between 13-16 hours/day, the illumination time is shortened from long to short, and the descending amplitude of the illumination time is controlled between 0.5-1 hour/day;
(2) in spring, the normal breeding season of the northern variety goose is in the current period, and the illumination time is controlled to be firstly shortened and then shortened;
(3) in the middle ten days from early summer to autumn, the period is the off-season propagation period of the northern variety goose, and the illumination time is controlled to be firstly shortened from long to short and then shortened from long to short;
(4) in the middle autumn to winter, the period is the off-season propagation ending period of the northern variety goose, and the illumination time is controlled to be firstly shortened from long to short and then shortened from short to long;
step two, controlling materials: when the extended illumination treatment is carried out, the feeding amount of the goose group needs to be controlled, the feeding amount of male breeding geese is required to be controlled to be 120 g/day at 100-;
step three, forced moulting: 1-3 days before molting, the concentrate fed before is gradually replaced by coarse feed, the feeding frequency is controlled to be 2-3 times/day after 3 days, the weight of northern variety goose is reduced by 35-40% after 10-12 days, meanwhile, the lighting of male breeding goose needs to be prolonged for 30-40 days, the lighting of female breeding goose needs to be prolonged for 50-60 days, and when the breeding goose has fallen off hair, the main and auxiliary wings and tail feather can be pulled off for forced molting;
step four, supplementary feeding: after molting, supplementing complete compound feed to the breeding geese, wherein the feeding amount of the male breeding geese is guaranteed to be 250 g/day, the feeding amount of the female breeding geese is guaranteed to be 200 g/day, then, the feeding amount is increased every two weeks for the female breeding geese and every week for the male breeding geese, and finally, the feeding amount is controlled to be 500 g/day at 450 times;
step five, avoiding light: the breeding geese are driven to the goose house in spring in the daytime to shade light and avoid summer heat, so that the living time of the breeding geese in a dark environment is prolonged, and the illumination time is reduced;
step six, production starting: an egg laying box is arranged for every five egg laying geese, and the five egg laying boxes are placed in a dark, dry and quiet place without harmful wind or cross wind invasion, so that the geese can lay eggs freely.
Preferably, the specific regulation and control steps of the prolonged illumination are as follows:
(1) in winter, the illumination time is controlled between 13-16 hours/day, the illumination time is shortened from long to short, and the descending amplitude of the illumination time is controlled between 0.5-1 hour/day;
(2) in spring, the normal breeding season of the northern variety goose is in the current period, the illumination time is controlled to be firstly shortened from long to short and then shortened from short to long: the illumination time is shortened from long to short, the time is controlled to be 12-8 hours/day, the time decreasing amplitude is controlled to be 1 hour/day, and the number of days for each decreasing is controlled to be 5-7 days; the illumination time is changed from short to long, the time is controlled to be 0-10 hours/day, the time increment amplitude is controlled to be 1 hour/day, the number of days for each increment is controlled to be 2 days, wherein the number of days for 0 hour/day is controlled to be 31 days;
(3) in the middle ten days from early summer to autumn, the period is the off-season propagation period of the northern variety goose, the illumination time is controlled to be firstly shortened from long to short, and then shortened from long to short: the illumination time is shortened from long to short, the illumination time is controlled to be 11-10 hours/day, the time decrement amplitude is controlled to be 1 hour/day, the period is an out-of-season egg laying transition period, the period belongs to an adjustment period, and the transition period is 23 days in total; after the transition period, the illumination time is adjusted to 10 hours/day, which is 80 days in total, for the normal egg laying of the goose, so that the egg laying performance of the goose can be effectively improved; when the goose lays eggs in the normal out-of-season egg laying period, the egg laying performance is reduced, the illumination time can be controlled to be changed from short to long, the time increment amplitude is controlled to be 0.5 hour/day for 3 days, and the aim is to stimulate the secretion of gonadotropin releasing hormone of the goose again so as to generate the inhibiting effect; adjusting the illumination time to 10 hours/day after 3 days, wherein the illumination time is 50 days;
(4) from late autumn to winter, the period is the off-season propagation end period of the northern variety goose, the illumination time is controlled to be shortened from long to short, then shortened from short to long, and finally shortened from long to short, and in the period, in order to prevent the northern variety goose from generating larger stress response, two transition periods are carried out: in the first transition period, the illumination time is shortened from long to short, the time is controlled to be 11 hours/day-natural illumination, the number of days for each descending is controlled to be 7 days, and the purpose is to enable the northern variety goose in the out-of-season to enter a normal physiological development period; in the second transition period, the illumination time is changed from short to long, namely natural illumination is-12.5 hours/day, the number of days for each descending is controlled to be 7 days, and the purpose is to relieve the stress reaction of the first transition period of the out-of-season goose; after the second transition period is finished, the illumination time is readjusted to be a long shortening period, the anti-season propagation regulation and control of the current year is formally finished after the two transition periods, the northern variety goose enters a normal rest period, and the overall regulation and control scheme for prolonging the illumination is shown in table 1:
TABLE 1 Overall Regulation scheme for extended illumination
Preferably, the extended light is controlled for a period of 13-16 hours/day from 12 months to 3 months for a total of 69 days.
Preferably, the light-proof time is 4-5 months, and the light-proof time is 1 month in total.
Preferably, the goose house is a greenhouse, the whole goose house is subjected to light-shielding treatment by two layers of black films, an exhaust fan is arranged every 2.5-3 m in the goose house, and a 40-watt blue bulb with the height of 2m is arranged every 3m in the goose house.
