Abstract
The invention relates to a method for rearing new strain of crude feeding tolerant chick, which comprises (1) organizing local chick group as F0, (2) rearing female and male F0 chick to sexual maturity, detecting their coarse fiber digestibility, selecting female and male chick with crude fiber digestibility greater than 17% as reserved breeding bird, organizing genealogy, breeding F1 chicks for 8 weeks, (3) Selecting part full-sib or half sib individuals from each genealogy, detecting the activity of cellulase in their caecum, raising F1 chicks to sexual maturity, detecting coarse fiber digestibility, selecting chick with crude fiber digestibility greater than 17%, Selecting chicks with high crude fibre digestibility and high cellulase activity according to the results of detection as reserved breeding bird, organizing genealogy, breeding F2 chick, feeding each generation newborn chick with diet with low protein and high crude fibre content, (4) repeating step (3), (5) rearing crude feeding tolerant chick line after 4-5 generations breeding.
Description
Technical field
The present invention relates to a kind of breeding method of coarse feed-resistance stocking chicken strain, belong to the cultural technique field.
Background technology
China's native chicken breed resource is numerous, and most kinds have all that outward appearance is beautiful, the bodily form is unique, meat meat flavour deliciousness, premunition are strong, the characteristics of crude feed tolerance, are the germ plasm resource of China's preciousness.
Summary of the invention
The object of the present invention is to provide a kind of breeding method of coarse feed-resistance stocking chicken strain.
Realize above-mentioned purpose for sending out, technical program of the present invention lies in adopting a kind of breeding method of new strain of coarse feed-resistance stocking chicken:
(1) sets up F0 for the local chicken group;
(2) F0 male and female chicken is supported to sexual maturity, measures the male and female chicken individuals to coarse-fibred digestibility, select crude fiber digestibility greater than 17% the male and female chicken establishment family of reserving seed for planting, and breeding F1 generation;
(3) F1 is for age in breeding chickling to 8 week, every family is selected its part full sibs or half sibs individuality, measure the activity of cellulase in its caecum, F1 is for supporting to sexual maturity, measure the male and female chicken individuals to coarse-fibred digestibility, selection to crude fiber digestibility greater than 17% male and female, while is in conjunction with the result of cellulase activity in each the family full sibs measured for 8 ages in week or the half sibs caecum, selection crude fiber digestibility height, and family or individuality that cellulase activity is high are reserved seed for planting, set up family, breed F2 generation, and cooperate low albumen simultaneously, the daily ration that crude fiber content is high each chick group from generation to generation that feeds;
(4) repeating step (3);
(5) through 4-5 for seed selection, cultivate the coarse feed-resistance stocking chicken strain.
The present invention further cultivates according to the characteristic of its crude feed tolerance, selects the crude feed tolerance chicken, and the crude feed tolerance chicken is strong to the coarse-fibred ability of digesting and assimilating, and can be used as to herd strain and carry out free range husbandry.Free range husbandry meets China's returning farmland to grassland, conceding the land to forestry, realizes the strategy of sustainable development that the woods grass is herded.
Embodiment
The breeding method of the coarse feed-resistance stocking chicken strain of present embodiment carries out according to the following steps:
(1) sets up local chicken family group;
(2) F0 male and female chicken is supported to sexual maturity, measures the male and female chicken individuals to coarse-fibred digestibility, select crude fiber digestibility greater than 17% the male and female chicken establishment family of reserving seed for planting, and breeding F1 generation;
(3) F1 is for age in breeding chickling to 8 week, every family is selected its part full sibs or half sibs individuality, measure the activity of cellulase in its caecum, F1 is for supporting to sexual maturity, measure the male and female chicken individuals to coarse-fibred digestibility, selection to crude fiber digestibility greater than 17% male and female, while is in conjunction with the result of cellulase activity in each the family full sibs measured for 8 ages in week or the half sibs caecum, selection crude fiber digestibility height, and family or individuality that cellulase activity is high are reserved seed for planting, set up family, breed F2 generation, and cooperate low egg simultaneously certainly, the daily ration that crude fiber content is high each chick group from generation to generation that feeds;
(4) repeating step (3);
(5) through 4-5 for seed selection, cultivate the coarse feed-resistance stocking chicken strain.
It should be noted last that: above embodiment is the unrestricted technical scheme of the present invention in order to explanation only, although the present invention is had been described in detail with reference to the foregoing description, those of ordinary skill in the art is to be understood that: still can make amendment or be equal to replacement the present invention, and not breaking away from any modification or partial replacement of the spirit and scope of the present invention, it all should be encompassed in the middle of the claim scope of the present invention.
