Description
Technical field
The invention belongs to crossbreeding technology field, especially a kind of breeding method of high-quality Luchuan pigs.
Background technique
" Luchuan pigs " is with a long history, best in quality, gains the name because originating in the Luchuan County with Southeast of Guangxi, now main distribution
In Yulin, Qiezhou, Wuzhou and other places.One of Chinese eight big Local Excellent pig kinds, have reproductive capacity is high, maternal instinct is good, resistance is strong,
The advantages that meat tenderness is delicious, figure is compact, genetic force is stablized, but Luchuan pigs body body is short and small, and back waist crosses recess, and abdomen mops floor greatly, stern
Portion is not plentiful enough, and the speed of growth is slow, and it is low that dressing percentage is low, lean meat percentage is low, feed conversion rate is low, sow produces nest number per year.
Summary of the invention
In order to solve the above technical problems existing in the prior art, the present invention provides a kind of breedings of high-quality Luchuan pigs
Method is realized particular by following technical scheme:
A kind of breeding method of high-quality Luchuan pigs, introduces the southern regions of the Yunnan Province microtia boar and local Luchuan sow mating generates F1 generation
Herd boar, introduction large white sow mate with local Luchuan boar and generate F1 generation broad sow, F1 generation herd boar and F1 generation broad sow
Mating, producing the F2 of cultivation for piglet is high-quality Luchuan pigs.
Preferably, the breeding method of the high-quality Luchuan pigs, comprising the following steps:
(1) the southern regions of the Yunnan Province microtia boar is introduced as male parent, and local Luchuan sow is selected as female parent, mating production F1 generation
The male piglet of 2-5 tire is bred as herd boar；
(2) raising of herd boar: step (1) resulting piglet is placed in pigsty, maintains the temperature at 25-30 DEG C, humidity
For 80-85%, every piglet is fixed nipple and breast-feeds, and when 10-15 age in days starts to feed pig starter feed A, and sooner or later 2 times daily,
Day, feeding amount was 80-100g/ head, and free water respectively sorts the good piglet of character in 30 ages in days, 2 monthly age, i.e.,
Obtain herd boar；
(3) introduce that large white sow is liquor-saturated to be used as male parent, local Luchuan boar selects the as maternal, mating production F1 generation
The female piglet of 2-5 tire is bred as broad sow；
(4) raising of broad sow: step (3) resulting piglet is placed in pigsty, maintains the temperature at 22-25 DEG C, humidity
For 70-80%, every piglet is fixed nipple and breast-feeds, and when 10-15 age in days starts to feed pig starter feed B, and sooner or later 2 times daily,
Day, feeding amount was 100-120g/ head, and free water respectively sorts the good piglet of character in 30 ages in days, 2 monthly age,
Up to broad sow；
(5) after broad sow and herd boar grow to adult, mating is carried out in oestrus and generates F2 generation；
(6) F2 is placed in piglet colony house for piglet, maintains the temperature at 24-26 DEG C, ambient humidity 87-89%, every
Piglet is fixed nipple and breast-feeds, and when 10-15 age in days herds piglet, starts feeding pig starter feed C, and sooner or later 2 times daily,
Day, feeding amount was 80-100g/ head, and free water respectively carries out the good piglet of character at 30 ages in days, 2 monthly ages and 5 monthly age
Sorting, obtains high-quality Luchuan pigs.
Preferably, the pig starter feed A, raw material include by weight 70-75 portions of corn flour, 10-15 parts of wheat skins,
20-25 portions of peanut cakes, 20-25 portions of buckwheats, 20-30 portions of sweet potato, 5-8 parts of chenopodium album linns, 3-5 portions of wild mint, 3-5 parts of stringy stonecrops, 1-2
Part bacillus subtilis, 0.5-1 parts of lactic acid bacterias.
Preferably, the preparation method of the pig starter feed A: corn flour, wheat skin, peanut cake, buckwheat are uniformly mixed, added
Enter bacillus subtilis, lactic acid bacteria, in 40-45 DEG C of fermentation 4-6h, obtains mixed fermentation material；By sweet potato, chenopodium album linn, wild mint,
Stringy stonecrop, which crushes, to be mixed, and water is added and decocts 40-60min, and mixed fermentation material is then added and mixes, and freeze-drying to water is 8-
10% to get pig starter feed A.
Preferably, the pig starter feed B, raw material include by weight 75-80 portions of corn flour, 10-15 parts of rice brans,
25-30 portions of peanut cakes, 8-10 portions of carrots, 8-10 parts of Lettuces, 6-8 portions of shepherd's purses, 3-5 Fen Vat slurry grass, 3-5 parts of grassworts, 0.5-1
Part bacillus subtilis, 0.2-0.4 parts of lactic acid bacterias.
Preferably, the preparation method of the pig starter feed B: corn flour, rice bran, peanut cake are uniformly mixed, and are added withered
Careless bacillus, lactic acid bacteria obtain mixed fermentation material in 35-40 DEG C of fermentation 5-7h；By carrot, Lettuce, shepherd's purse, Vat slurry
Grass, grasswort, which crush, to be mixed, and water is added and decocts 1-1.5h, and mixed fermentation material is then added and mixes, and freeze-drying to water is 8-
10% to get pig starter feed B.
Preferably, the pig starter feed C, raw material include 75-80 corn flour, 8-10 parts of wheat skins, 25- by weight
30 portions of soya-bean cakes, 10-15 portions of cucumber, 8-10 portions of pumpkins, 1-2 portions of Schisandra chinensis, 3-5 portions of motherworts, 3-5 portions of certain herbaceous plants with big flowers dishes, 0.5-1 portions of withered grass
Bacillus, 0.2-0.4 part lactic acid bacteria.
Preferably, the preparation method of the pig starter feed C: corn flour, wheat skin, soya-bean cake are uniformly mixed, and withered grass is added
Bacillus, lactic acid bacteria obtain mixed fermentation material in 35-40 DEG C of fermentation 5-7h；By cucumber, pumpkin, Schisandra chinensis, motherwort, certain herbaceous plants with big flowers
The broken mixing of vegetable powder, is added water and decocts 1.5-2h, and mixed fermentation material is then added and mixes, and freeze-drying to water is 8-10%, i.e.,
Obtain pig starter feed C.
Present invention selection back waist is broad, whole body is plentiful, village rouge power is strong, and dressing percentage is high, and thin skin bone is thin, fine and tender taste is delicious,
The southern regions of the Yunnan Province microtia pig of heat-resisting, moisture resistance, resistance to crude feed hybridizes with Luchuan pigs generates F1 generation herd boar, and it is short and small to overcome Luchuan pigs body body,
The disadvantages of waist crosses recess, abdomen mops floor greatly, while heat-resisting, moisture resistance performance is enhanced, it is more suitable for supporting in the Guangxi of high humidity, high temperature
It grows；The Large White that selection feed conversion rate is high, dressing percentage Gao, Of-thin meat rate is high, the speed of growth is fast hybridizes with Luchuan pigs generates F1 generation
Broad sow, the speed of growth is slow, and dressing percentage is low, lean meat percentage is low, feed conversion rate is low, sow produces the low disadvantage of nest number per year, improves
The economic benefit of cultivation；F1 generation herd boar hybridizes the F2 generated with F1 generation broad sow for piglet, high temperature resistant, high humidity environment, conversion
Rate is high, dressing percentage Gao, Of-thin meat rate is high, the speed of growth is fast；Using special feed respectively to F1 generation herd boar, F1 generation broad sow,
F2 is raised for piglet, can be provided the nutriment of abundance and be improved the survival rate of piglet, piglet survival ratio is up to
93% or more, while the digestion power and immunocompetence of piglet can be enhanced.
Specific embodiment
Tuberculosis specific embodiment is limited technical solution of the present invention is further below, but claimed
Range is not only limited to made description.
