Abstract
The invention relates to the technical field of livestock and concretely relates to a seed selection method for excellent commercial pigs. The method comprises the following steps of (A) selecting Baixi pigs as the first-generation patriarchal seed and the first-generation maternal seed for mating, selecting excellent Baixi pigs produced after the mating as the terminal maternal seed, (B) selecting Berkshire pigs as the second-generation patriarchal seed and the second-generation maternal seed for mating, and selecting excellent Berkshire pigs produced after the mating as the terminal patriarchal seed, and (C) hybridizing the excellent Baixi pig terminal maternal seed produced via the step (A) and the excellent Berkshire terminal patriarchal seed produced via the step (B) to acquire excellent commercial pigs. Through the scientific seed selection method, terminal maternal seed and patriarchal seed can be selected in the primary stage, and excellent Berkshire pig terminal patriarchal seed and excellent Baixi pig terminal maternal seed can be produced; with an artificial insemination method, the two seeds are hybridized and excellent commercial pigs can be produced, can be quickly fattened and give birth more babies and great meat quality; and butchering efficiency and production efficiency can be improved.
Description
Technical field
The present invention relates to technical field of livestock husbandry, specifically the selection of a kind of high-quality commercial pig.
Background technology
Washing pig in vain and have another name called seedling stockaded village pig, be the famous high-quality indigenous pig kind in Guizhou, hair is black, body is short, crude feed tolerance, meat are tender, delicious, and what producing region, center was distributed in Shibing County washes the ground such as the paddy Gansu Province with Huangping County, Weng Ping in vain. Build is medium, and skin is micro-red, and head size is moderate, and hair style is comparatively upright, and face is micro-recessed, there is irregular darker wrinkle in volume portion, and mouth cylinder is thick, and the medium size of ear is sagging to both sides, and back of the body waist is more straight, but how recessed Suprapubic arch sling is, abdomen is sagging greatly to mop floor, and buttocks relatively tilts, the many gauffers of thigh, many sleeping systems. By hair black, minority individuality Sheng Baimao in acra or tail end. Sow body weight of growing up is 65.8kg. The farrowing of Suprapubic arch sling nest is 8, and the stage of fattening, day weight gain was 200g/d, and dressing percentage is 68.5%, fat thickness 3.5cm, eye muscle area 15.2cm2��
Duroc is male parent and washes pig hybridization of female parent in vain, market pig meat colour-difference, taste are poor, snowflake meat, streaky pork are not up to standard, the yellow fat pig of more than 5% is had to produce, former sterling kind washes pig in vain, individual little, growth is slow, fat is many, farrowing quantity is low, dressing percentage is low and opposing respiratory tract disease is poor, it is not high that economical efficiency is fattened in raising.
Summary of the invention
For above-mentioned weak point of the prior art, it is desirable to provide a kind of meat is good, farrowing quantity is many, fatten the selection of fast and that dressing percentage is high high-quality commercial pig.
For solving the problems of the technologies described above, the selection of the high-quality commercial pig of the present invention, comprises the following steps:
A) selecting that white to wash pig be the first male parent with washing pig in vain is first maternal, carry out mating, choosing produce outstanding, to wash pig in vain be terminal female parent;
B) selecting Berkshire to be the 2nd male parent and Berkshire to be the 2nd female parent, carry out mating, choosing the outstanding Berkshire produced is terminal male;
C) being hybridized by the outstanding outstanding Berkshire terminal male produced in pig terminal female parent and step B of washing in vain produced in steps A, hybridization obtains high-quality commercial pig.
Further, in described steps A wash that pig terminal female parent is that mao colour purity is black, build is medium, skin is red, hair style is upright in vain, face micro-recessed, back of the body waist is straight washes pig in vain.
Further, the Berkshire terminal male in described step B is lean ratio height, meat proterties is good, appearance traits consistent and anti-stress without fluothane recessive gene Berkshire.
Further, the Crossing system in described step C is artificial insemination.
The selection of high-quality commercial pig of the present invention, by terminal female parent and the seed selection of terminal male in early stage, the selection of employing science, the Berkshire terminal male of the high-quality produced and high-quality wash pig terminal female parent in vain, hybridized by the mode of artificial insemination, the high-quality commercial pig produced not only is fattened soon, farrowing is many, meat good, and improves dressing percentage and production efficiency.
Embodiment
Below the technical scheme in the embodiment of the present invention is clearly and completely described. Obviously, described embodiment is only a part of embodiment of the present invention, instead of whole embodiments. Based on the embodiment in the present invention, those of ordinary skill in the art, not making other embodiments all obtained under creative work prerequisite, belong to the scope of protection of the invention.
Embodiment 1 washes the seed selection of pig in vain
To wash pig in vain as seed selection group, seed selection group blood lineage reaches 5, quantity 100 male and female ratio 1:5, adopt conventional breeding means, be bred as hair colour purity black, build is medium, skin is red, hair style is upright, face micro-recessed, the back of the body waist straight wash swinery body in vain.
The seed selection of embodiment 2 Berkshire
Taking Berkshire as seed selection group, seed selection group blood lineage reaches 5, quantity 100 male and female ratio 1:5, adopts conventional breeding means, be bred as that lean ratio height, meat proterties are good, appearance traits consistent and anti-stress without fluothane recessive gene Berkshire colony.
Embodiment 3 hybridizes the seed selection of high-quality commercial pig
Being terminal female parent by the pig of washing in vain in embodiment 1, the Berkshire in embodiment 2 is terminal male, adopts the Crossing system of artificial insemination to hybridize, and hybridization obtains high-quality commercial pig and also high-quality commercial pig carried out routine and fattens and slaughter determining. By technology of artificial insemination, farrowing rate improves, primitive pit litter size 8-9 head, and existing nest litter size 10-12 head, goes out 2-3 head, it is to increase 33% more. Thus improve production efficiency.
Embodiment 4 combining ability test
The combining ability test of each Cross type of table 1
Result: the average daily gain of high-quality commercial pig reaches more than 710g/d, and lean ratio reaches more than 65%, feedstuff-meat ratio, lower than 2.6, without PSE meat, can shift to an earlier date 10-15 days and go out fertilizer, production efficiency height.
The selection of high-quality commercial pig of the present invention, by terminal female parent and the seed selection of terminal male in early stage, the selection of employing science, the Berkshire terminal male of the high-quality produced and high-quality wash pig terminal female parent in vain, hybridized by the mode of artificial insemination, the high-quality commercial pig produced not only is fattened soon, farrowing is many, meat good, and improves dressing percentage and production efficiency.
