The present embodiment provides a kind of black pig cultural methods, comprising the following steps:

One, breeding facility

600 square metres of area booth type pig house 20 is built, inside is divided into herd boar area, sow breeding area, piglet guarantor Area and fattening area are educated, 3000 square metres of fences are built in the forest land of pig house periphery as sports ground, using original fish pond as play Pond, inhering architecture is as Service center and raising warehouse.

Two, aquaculture management

(1) suckling pig management (referring to the piglet from being born to the stage of weaning)

S101: heat preservation is against pressure

Controlling pig house temperature is 18.3~22.1 DEG C, and relative humidity is 49.7%~70.4%, keeps air fresh；Pig house Guard rail is installed equipped with incubator and/or moist closet, and in childbirth column.Wherein, 1~7 age in days be 31.8~28.3 DEG C, 8~ 35 ages in days are 27.7~23.5 DEG C, in incubator bottom or infrared lamp of one 250 watts away from 30~40 centimeters of moist closet bottom extension Bubble.

S102: sufficient colostrum and fixed nipple are eaten

Sufficient colostrum is eaten after piglet is raw in 1 hour, fixes nipple in 2~3 ages in days after life；Wherein, fixed nipple to be selected as certainly It is main, supplemented by individual adjustment, the small piglet of litter weight at birth is fixed on front-seat nipple, the big piglet of litter weight at birth is fixed on heel row Nipple.

S103: iron and excessively young and nest are mended

Intramuscular injection iron preparation, every dosage 100~150mg iron in 2~3 ages in days after piglet is raw；The lactating sow every food in one's mouth It is 10~12 young, the principle for the sow son excessively that the piglet more than 12 or less than 7 is produced backward by the piglet first produced is produced to nest, The piglet fed is crossed to cross to term difference no more than 3 days, few sow foster nursing of farrowing；Piglet must eat sufficient colostrum before crossing the food in one's mouth；To production Two nest piglets can be merged 1 nest by excessively young principle by young very few sow, and good by a constitution, the sow of Full milk secretion feeds It educates；Sufficient colostrum must be eaten before piglet and nest.

S104: food and feed supplement are opened

5 ages in days training drinking-water after piglet is raw, food is opened in the training of 7 ages in days, until 20 ages in days all open food；After piglet opens food, mend Full price batch is fed, is used raw wet feed type (material-water ratio 1:0.5), day feeds 5~6 times.

S105: 25 age in days castrations after piglet is raw, the wean of 35 ages in days obtain weanling pig.

(2) child care swine rearing management (pig since wean to 70 ages in days is known as child care pig)

S201: although child care pig enhances the adaptation of environment than newborn piglet, compared with Adult Pig, still there is a big difference, because This this period mainly controls pig house environment and suitable stocking density, reduction stress, control disease；Therefore, child care is controlled Give up temperature be 20~26 DEG C, stocking density be 0.6~0.8 square metre/head, weanling pig using sucking pig material feed 5~8 days, then With sucking pig material and baby pig feedstuff mixed feeding, sucking pig material ratio is during which gradually decreased, all uses baby pig feedstuff instead after 10~14 days, it After be freely eaten.

S202: when black 70 age in days weight of porkling pig reaches 30 kilograms, selecting the individual of physical health to give over to kind of a use, enters The management in replacement gilt stage；The fattening house that is transferred to not done kind is fattened.

(3) herd boar feeding management

S301: in the breeding process of black pig herd boar, herd boars stay in-rise in order to prevent, are easy to appear and climb mutually Across, fight phenomena such as, thus influence breeding quality, so herd boar will take separated raising.The feeding of herd boar is wanted Focus on the equilibrium of nutrition, scale of feeding wants moderate, herd boar to be made to keep the medium growth of livestock throughout the year, can not be too fat and too thin, it to keep Strong constitution, abundant energy, vigorous sexual desire and good semen quality.Therefore, herd boar takes separated raising, and every 2~3 kilograms of concentrated feeds of it every feeding, daily feeding 2 times.

S302: during breeding, for the sexual desire for keeping boar vigorous and good semen quality, should add in daily feed Add 1 to 2 fresh hen egg and feed appropriate green vegetable leaf etc..It is suitable to move the constitution that black pig herd boar can be enhanced, improve kind of a public affairs The sexual desire and sperm of pig カ living, so herd boar is needed to carry out regular outdoor sports daily.30~60min of movement every time, The time of movement, winter was preferably selected in noon, and summer is selected in be advisable sooner or later according to outdoor temperature situation.

S303: observing the heat situation of black pig broad sow, and black pig broad sow conception rate and produce surviving of son can be improved in breeding in due course Rate.It was found that the vaginal orifice of sow is red and swollen, have liquid outflow, quiet vertical reflection occurs illustrates that sow is in season.At this moment keeper can To press sow back with hand, oestrus of sow can determine if sow plants oneself.Before mating, first will to herd boar and The private parts of broad sow is cleaned and is wiped, and bacterium and dirt is avoided to bring sow vagina into.When herd boar climbs up broad sow back When, it needs poultry raiser to observe, needs to carry out human assistance when necessary and promote going on smoothly for mating.Black pig breeding is handed over using nature The breeding ratio of the mode matched, herd boar and broad sow is 1:25~1:30, the effective time of breeding be after heat starts about Between 12~36 hours；First service should be completed in 12~16 hours after starting quiet vertical heat and being detected, in order to improve Pregnancy rate and produce surviving of son rate spend 12 hours and carry out second of breeding again.

(4) feeding management of sow gestation phase

S401: if black pig sow heat does not occur within 20~40 days after breeding again, tentatively it is judged as and has cherished It is pregnant, into the stage gestational period.The sow gestation phase refers to the ovum fertilization of sow to this period of production.Black pig sow gestation week Phase average out to 113.5 days.The black pig gestational period and other boar-samples need to carry out meticulous treatment.It should guarantee that sow has well Body condition, also to prevent miscarriage and promote the growth and development of embryo.The feeding management of this section of feeding period is broadly divided into two stages, pregnant It is pregnent early period and latter half of gestation.In addition, black pig will realize the diversification and adaptability of feed as far as possible, mainly have: corn, wheat Son, sweet potato, potato, paddy, wheat bran etc., in addition as succulent fodders such as dish leaf, green grass, carrots, feed arrangement can be according to working as Depending on ground actual conditions.

S402: first 80~94 days of black pig sow pregnancy are first half period of gestation, during which pay attention to preventing miscarriage, and reduce simultaneously column, every daily Head 2~2.2 kilograms of concentrated feeds of feeding, daily feeding 2 times.

S403: sow antenatal 20~30 days be latter half of gestation, during which uses separated raising；Every feeding 3~3.5 thousand daily Gram concentrated feed, sow is in antenatal material reducing in 2~3 days 30% or so, antenatal 24 hours not feedings.

S404: farrowing house keeps hygienically clean, and rinsed the delivery room giant on empty column at antenatal 2~3 days, disappears Poison, windowing ventilation, call in delivery room after thoroughly drying, then by sow；Sow calls in front of delivery room and first has a bath to sow, after disinfection again Into delivery room；Baffle is put on the upper surface of piglet heat-insulation column and lagging facility is installed.

S405: entering nursing period management phase after sow smoothly gives birth to piggy, and sow postpartum 3 days, according to mother Pig appetite launches feed, gradually feeds, and reaches free choice feeding level after 3 days；Daily feed intake is up to 3.5~5.5 kilograms, wean Preceding gradually material reducing in 3 days, the wean same day stop feeding.

Wherein, the sow nonpregnant stage and pregnancy head 80 days based on greenfeed, high-quality roughage and pomace and dreg fodder, daily The only fine fodder of 1 kilogram or so of collocation；1 month just before giving birth preceding, it is fed for 2~3 kilograms of fine fodders daily.To both ensure that normal fetal Development, sow one tire of every pregnancy can also save 60~90 kilograms of concentrated feed.30 age in days of boar pig, the castrating of 40 age in days of gilt, point Not than the 60 ages in days castrating weight gain 15% or so of people's habit, and wound healing is very fast.By the wean of 60 age in days of piglet ahead of time to 40 ~45 days, sow morning heat, early breeding can be promoted in this way, shorten the nonpregnant phase, it is opposite to save feed.

(5) growing-finishing pig management (referring to the black pig in weight 25~90kg stage)

In large-scale production pig farm, make the pig of commodity production, be generally used straight fatting method, is bred as the stage It is difficult to divide with the fattening stage, therefore is referred to as growing-finishing pig；In R&D institution, for the pig of research, weight 25~60kg stage Circle is divided to raise after making grower pigs, weight 60~90kg stage be black 60 age in days of pig of fattening pig, 10 pigs of every circle or so, Yi Mianqi It plays outdoors and chases after race energy consumption.

Using the breeding technology of " preceding spacious then control ", health and disinfection treatment are during which periodically carried out." preceding spacious " refers to the black pig of meat Before 50 kg body weights, repeatedly feeding or free choice feeding, feed are without restriction daily；And weight is after 50 kilograms, daily In addition to guaranteeing sufficient drinking-water, only hello two meal, every meal only feed 8 ninety percent and satisfy, i.e., so-called " rear control ".Because the black pig of meat is at 50 kilograms After, fat based on depositing, accelerate by growth, if feeding too full, the black pig of meat will how long fatty, and lean meat is reduced.Health with Disinfection treatment specifically includes: cleaning colony house daily and removes excrement 2 times, gives up internal channel 2% caustic soda aqueous solution or other disinfectants weekly Disinfection 1 time.

Test proves: for the black pig weight of meat at 40 kilograms~60 kilograms, the lean meat increased daily is 288 grams, fat 280 Gram；And after 90 kilograms, daily long lean meat only has 120 grams, and fat is the 2 times or more of lean meat.Therefore, the black pig of lean meat species is supported It must control and butcher listing in 90 kilograms~double centner.Simultaneously it is noted that humidity and temperature management to pig, the preference temperature of pig are 15~25 DEG C, relative humidity is 55%~60%, if temperature, humidity are excessively high, easily leads to heatstroke and dysbolism, therefore work as summer When temperature is more than 28 DEG C, noon is had a shower cage with water, sunshade of puing up a shed；If temperature, humidity are too low, the heat dissipation of pig body is more, consumes and raises Material is more, will increase feeding cost, therefore to carry out warming in winter, the hay of 10~15cm of place mat thickness is needed in cage, simultaneously Use warm water spice.

Specifically, black pig will guarantee various reasonable, the nutrition comprehensive and abundant of feed during feeding.It is the greenfeed of pig feeding, thick Feed and concentrated feed, it is reasonably combined, guarantee pig to the needs of various nutrition.According to the relationship of daily ration volume and pig feed intake, weighing apparatus Amount feed volume size can use diet dry matter content.Need diet dry matter 2.5~4.5 public daily by every 100 kg body weight of pig Jin calculate, greenfeed, roughage, 3 kinds of feeds of concentrated feed dry matter ratio should be 5:3:2.In terms of greenfeed, select it is fresh and tender, Grass seeds leafy, protein content is high, palatability is good；Herbage should be dried before feeding, and general pig feeds 2~3 times daily.It is public (mother) pig, growing and fattening pigs can be used 1 day 2 times, piglet and can feed 3 times for grower pigs 1 day.Midday skies should be avoided most in feeding time arrangement When hot and period that personnel activity is most frequent.Specifically, concentrated feed includes corn, dregs of beans, oat, fish meal, bone meal and oil meal One of or it is a variety of；Roughage includes one of wheat bran, zein fiber and vinasse or a variety of；Greenfeed includes beet, radish With one of herbage or a variety of；High quality forage includes one of clover, witloof and sugar grass or a variety of；Chinese herbal medicine includes sweet One of grass, honeysuckle, chrysanthemum, ginger and Radix Isatidis are a variety of.

The black pig that above-described embodiment is raised has the advantage that (one) black pig whole body black wool, performance are stablized, figure essence Ingeniously, reaction is quick, and disease-resistant performance is strong with reproductive capacity, resistance to cold food.The more smart reality of leg, slice is with beautiful marble lines.By It is put in a suitable place to breed in forest zone, raises the thin meat of the whole body congealed fat, concentrated fine and tender taste, meat flavour mellowness, nutty, it is fat but not greasy.(2) it raises Phase is long: the common white pig of lean meat species is delivered for sale from birth to 100 kilograms, and feeding time is generally 150~160 days；The black pig of the present invention Feeding period must be 12 months.Feeding period is long to be conducive to pork trunk maturation and flavor substance richness product.(3) the black pig of the present embodiment The color of meat is best cerise, and Color Score 3.17, pH value 6.28, moisture holding capacity 73.89%, intramuscular fat content are for 24 hours 3.48%, Meat Tenderness is the external thin pig kinds such as the excellent Landrace of pork quality traits and Yorkshire Pigs such as 3.66kg (shear forces). (4) content of four kinds of amino acid is apparently higher than the external pig kind such as Landrace in the black pork of the present embodiment；Four kinds of amino acid refer to pair Threonine, alanine, glutamic acid and the lysine and cysteine that the flavor of meat plays a crucial role.(5) the black pig of the present embodiment Meat flavour is delicious, and fresh keeping time is long；Constitute the content of the nucleotide of delicious meat together with free amino acid, hence it is evident that be higher than Yorkshire There is 1~4 day of peak after slaughter in the content of pig inosinic acid.(6) unsaturated lipid in the black pig muscle of the present embodiment Fat acid is apparently higher than Landrace, especially higher containing amino acid (cystine) content, has higher nutrition and guarantor to human body after edible Strong effect.(7) more external wide in variety of the black pig muscle fibre number of the present embodiment, the diameter of fiber is all kinds of thinner than external, It is edible fine and tender taste, in good taste.(8) the black pork of the present embodiment includes abundant irony, protein and vitamin, these are all Advocate the nutrient that the modern pole of diet lacks, special cholesterol level and fat are all lower than common pork, the black pig of the present invention Still content is much lower in terms of fat for meat." holoprotein " contained by the black pork of the present invention can more assist repairing tissue, Often eating the black pork of the present invention can provide balance safe and comfortable nutrient, and modern still can obtain minerals in diet, tie up him Life and protein, long security personnel's health.Comparable with common pork, even more it is seen that the advantages of black pork of the invention, and these are excellent Select what often common pork was much less than.
