Abstract
The invention discloses a kind of laying hen selection and breeding method for new strain of raising breeding group based on commodity egg chicken coop.The present invention is based on breeding group laying period adopts commodity egg chicken coop to raise, and by setting up family, collects kind of an egg, by cage item row egg, enters to incubate; Family and hen is eliminated according to fertility rate of hatching egg; Family is eliminated again according to embryo egg hatchability of living; To select and remain again cock; On the basis of families selecting, then eliminate hen according to an equal egg number, eliminate the cock of family of not reserving seed for planting simultaneously; Based on last hen number of reserving seed for planting, from the family of reserving seed for planting, select cock by a certain percentage, set up and adopt artificial insemination mode to breed next family from generation to generation; Collecting kind of an egg, repeating above step to cultivating laying hen new lines; The present invention both ensure that the Breeding Effect of the proterties such as egg production, and the gregarious adaptability of indirect selections, significantly reduces again writing task amount.
Description
Technical field
The invention belongs to poultry breeding technical field, be specifically related to a kind of laying hen selection and breeding method for new strain of raising breeding group based on commodity egg chicken coop.
Background technology
Traditionally, the low-heritability traits such as laying hen egg yield, fertility rate and hatchability all adopts families selecting method or family in conjunction with system of selection in family.No matter adopt which kind of system of selection, its breeding group's laying period, all needs single cage to raise, with proterties such as recording individual egg numbers.Objectively exist, part breeding and the increase of Zhong Ji production integration enterprise along with selected strain number and the raising of Selective Pressure, individual cage bit quantity Chang Buneng meets seed selection needs; Part raises the enterprise of Local chicken breeds chicken, but needs to select local chicken egg laying performance without individual cage position; And the single cage raising of breeding group is unfavorable for the problems such as gregarious adaptive natural selection; Invent a kind of laying hen selection and breeding method for new strain of raising breeding group based on commodity egg chicken coop, have important practical significance.
Summary of the invention
The object of the invention is to provide a kind of laying hen selection and breeding method for new strain of raising breeding group based on commodity egg chicken coop, can reduce writing task amount, solves the single cage raising of breeding group and is unfavorable for gregarious adaptive natural selection problem.
For realizing object of the present invention, the technical scheme of employing of the present invention is:
Raise a breeding group's laying hen selection and breeding method for new strain based on commodity egg chicken coop, comprise the steps:
(1) by every 5 cage positions, 3, each cage position hen, or joining 1 cock by every 4 cage positions, 4, each cage position hen is 1 family, sets up 80 ~ 100 familys altogether, collects 14 ~ 28 days kind eggs, write family number and cage item the microcephaly of each egg, by cage item row egg, enter to incubate;
(2) measure and add up the fertility rate of hatching egg of each cage position and the fertility rate of hatching egg of each family respectively; Eliminate the low family of 2% ~ 5% fertilization rate or fertilization rate lower than 90% family; Again in each family, the hen in the cage position that superseded fertilization rate is minimum or fertilization rate are lower than the hen in the cage position of 90%;
(3) by the hatching of cage item, wear wing number, record the family number of every chick, cage item and wing number; Add up the embryo egg hatchability alive of each family, eliminate the low family of 2% ~ 5% incubation rate or incubation rate lower than 90% family;
(4) brood the end of term, observe according to a conventional method, select the proterties such as individual appearance and body weight, each family is selected and remain cock 8 ~ 10;
(5) be bred as the end of term, observe according to a conventional method, select the proterties such as individual appearance and body weight; Each family is selected and remain cock 6 ~ 8; Concentrated by all hens of reserving seed for planting of each family, the hen number of elements-3 can placed by each cage position or 4 are 1 group of random packet, often organize chicken and put into a cage position, often organize chicken random distribution in house;
In (6) 19 ~ 40 week age, observe and record the proterties such as chicken number and egg number of each cage position every day; 23-24 age in week, measure the semen quality of every cock, each family is selected and remain 4 ~ 5 cocks that sperm viability is high, sperm volume is many;
In (7) 41 ~ 42 week age, calculate each cage position respectively, each family and Quan Qunkai produced for-40 ages in week only equal egg number, eliminate family only all egg number lower than the family of full group only equal egg number, eliminate the cock of family of not reserving seed for planting simultaneously; Again in each family of selecting and remain, eliminate the hen in the cage position that only all egg number is minimum;
(8) 43 ~ 44 week age, based on last hen number of reserving seed for planting, the hen number of elements-3 that each cage position can be placed or 4, determine male and female chicken than 1: 15 or the ratio of 1: 16 from the family of reserving seed for planting, select cock, these cocks are selected from each family moderate as far as possible; Again by every 5 cage positions, 3, each cage position hen, or join 1 cock by every 4 cage positions, 4, each cage position hen, set up and adopt artificial insemination mode to breed next family from generation to generation;
(9) collect 14 ~ 28 days kind eggs, write family number and cage item the microcephaly of each egg, by cage item row egg, enter to incubate; Observation eggshell color, egg size, egg type before entering to incubate, rejecting 10% ~ 20% eggshell color crosses dark or excessively shallow, egg size is excessive or too small, the egg that egg type is long or excessively round, repeat step (2), (3), (4), (5), (6), (7), (8), (9), to cultivating laying hen new lines.
The cage position used refers to the separate space separated by commodity egg chicken coop aperture plate, if raise cage floor space shared by medium-sized laying hen every chicken to be greater than 450cm
2, light-duty laying hen or local laying hen then every only shared cage floor space are greater than 380cm
2
The wing number used in step (3) is serial number, i.e. " ××× ×× ".
Affinity-less relation in two generations between the male and female chicken of the next family from generation to generation of the middle breeding of step (8).
The present invention is based on breeding group laying period adopts commodity egg chicken coop to raise, and 3 or 4 hens are raised in each cage position, in units of cage position, record the proterties such as egg number, and innovation choice method cultivates laying hen new lines; Both ensure that the Breeding Effect of the proterties such as egg production, the gregarious adaptability of indirect selections, significantly reduces again writing task amount.
