Description
Technical field
The invention belongs to beaver rabbit seed selecting technique fields, more particularly to a kind of four stage beaver rabbit seed choosing methods.
Background technique
Performance test is work most basic in breeding, and beaver rabbit breeding requires to implement productivity with strictly regulating first
It can measure, the various performance inventory data of acquisition simultaneously carry out statistical disposition and the breeding analysis of science, then further take phase
The breeding measures answered.The accurate performance measurement of system is the premise of science seed selection and the foundation of population evaluation and management.
Animal husbandry developed country pays much attention to establish livestock and poultry production performance measurement system and institutionalization.
Beaver rabbit seed selection, which mainly divides 5 times, to be selected:
(1) it selects: generally being carried out in wean for the first time, mainly with pedigree achievement and weanling weight alternatively foundation,
Furthermore the eurhythmia degree of littermate rabbit should be cooperated to be selected, weaned newborn rabbit is allocated as breeding group and productive group.
(2) it second selects: generally being carried out at 3 monthly ages, selecting emphasis is the speed of growth and fleece quality, can be by 3 monthly ages
Weight and appearance (fleece quality) scoring building selection index.Figure is big, fur quality is good, premunition is strong, reproductive system without
Abnormal individual gives over to kind of a use, eliminates small, the weak individual of body.
(3) third time select: generally carried out at 5~6 monthly age, this be beaver rabbit in life hair quality, hair color performance most sufficiently,
The period of most standard, and kind rabbit are just matched the period that skin is taken with commodity rabbit.With production performance and external form identification based on, eligible into
Make preparations for sowing rabbit group after entering, and failure does commodity rabbit and takes skin, carries out sexual desire and semen quality inspection to buck, sends out female rabbit
Feelings, reproductive organs inspection, nonconforming person are not used as kind.
(4) the 4th selections: general progress about one year old, the reproductive performance of major diagnostic kind rabbit, superseded Repeat breeding,
Reproductive performance not good mother rabbit and the buck that sexual desire is low, semen quality is poor, breeding capacity is not strong.
(5) the 5th selections: i.e. outstanding kind of rabbit is included in core group by progress progeny testing, and general person is breeding rabbit group.
In conclusion problem of the existing technology is:
(1) wean generally in 35 ages in days, beaver rabbit is larger by maternal effect at this time, therefore should be changed to 56 ages in days, i.e. 8 week old into
Row selects for the first time;
(2) selection index only is constructed in second of selection, it is sufficiently complete;
The times of (3) the 4th selections are somewhat too long because female beaver rabbit is at 6 monthly ages, public beaver rabbit 7 monthly ages just property at
It is ripe, it can be by time advance to 6 monthly ages and 7 monthly ages;
(4) although the 5th time selects to improve seed selection accuracy, after only milk cow applies in agricultural animal so far
Descendants' method for measuring, therefore the 5th selection is removed.
Summary of the invention
In view of the problems of the existing technology, the present invention provides a kind of four stage beaver rabbit seed choosing methods.
The invention is realized in this way a kind of four stage beaver rabbit seed choosing methods, the four stages beaver rabbit seed choosing method according to
Growth of Rex rabbits, coat law of development, using 8 week old, 13 week old, 23 week old, 6 monthly ages/7 monthly ages, four stage seed choosing method.
(1) first stage choosing method includes: that 8 week old carry out first time selection, individual multiple selection index > 100,8 week old
The individual of weight 1250.00g or more leaves continuation breeding, and ratio of reserving seed for planting is 400% or more of breeding core group quantity.
(2) it carries out second when second stage choosing method includes: 13 week old to select, individual multiple selection index > 100,13
The individual of week old weight 2200.00g or more leaves continuation breeding, and ratio of reserving seed for planting is 300% or more of breeding core group quantity.
(3) third time selection, individual multiple selection index > 100,23 are carried out when phase III choosing method includes: 23 week old
The healthy individuals of week old weight 3000.00g or more leave continuation breeding, ratio of reserving seed for planting be breeding core group quantity 150% with
On.
(4) the 4th selection is carried out when fourth stage choosing method includes: female 6 monthly age of rabbit, 7 monthly age of buck, female rabbit is by individual
Multiple selection index > 100, weight 3500.00g or more, number of nipples 4 to reserving seed for planting above;Buck presses individual weight, appearance traits, is good for
Health situation, the selection of testicualr development situation, weight 3500.00g's or more gives over to kind of a use, and ratio of reserving seed for planting is breeding core group quantity
100% or more.
Another object of the present invention is to provide a kind of beaver rabbits using the four stages beaver rabbit seed choosing method breeding.
Advantages of the present invention and good effect are as follows: according to growth of Rex rabbits, coat law of development, using 8 week old, 13 week old,
23 week old, 6 monthly ages/7 monthly ages " four stages " seed choosing method.The present invention carries out stage selection (totally four times selection), stays selected more, adds
Big selection is poor, improves selection reaction.
(1) according to growth of Rex rabbits, coat law of development, using 8 week old, 13 week old, 23 week old, 6 monthly ages/7 monthly age " quadravalences
Section " seed choosing method.The present invention carries out stage selection (totally four times selection), the main advantages of the present invention and good effect show:
1. weaning generally in 35 ages in days, beaver rabbit is larger by maternal effect at this time, therefore should be changed to 56 ages in days, i.e. 8 week old into
Row selects for the first time;
2. the time of the 4th selection is somewhat too long because female beaver rabbit is at 6 monthly ages, public beaver rabbit 7 monthly ages just property at
It is ripe, it can be by time advance to 6 monthly ages and 7 monthly ages;And original method is 1 year or so, therefore when being advanced by selection in 5~6 months
Between, it has saved for 41.67%~50% time, has substantially reduced the generation inteval.
Although only having milk cow in agricultural animal 3. the 5th time selects to improve seed selection accuracy so far and applying descendant
Method for measuring, therefore the 5th selection is removed.
