Description
Technical field
The present invention relates to a kind of method of utilizing Huaihe River pig and wild boar to produce the hybridization market pig, belong to the herding production field.The hybridization market pig of adopting this method to produce, fully utilized Huaihe River pig and the wild boar advantage aspect lean meat percentage, meat, crude feed tolerance, premunition, introduce certain Du Luoke blood lineage simultaneously, improved growth rate, thereby had higher edible quality and economic worth.
Background technology
Wild boar belongs to Suidae, and its disposition is comparatively violent, well-developed for limbs, is a kind of wildlife of being good at running.The boar feedstuff scope is wide, and digestion power is strong, and the meat feed ratio valency is higher, and carcass lean meat percentage is higher than tame pig, and meat is tender and crisp, and unique fragrance is arranged.Wild boar is tamed artificial feeding; or utilize wild boar through the domestication with good bacon hogs or local breeding pig hybridization cultivation new product boar or produce tame wild hybridized pig (being also referred to as special wild boar), can reach the resource that saves the wild animals, increase economic benefit, enrich the purpose of human food's kind.
If can utilize the merit of wild boar and tame pig, take the technological means of genetic breeding, cultivate the new product boar, the best way of wild boar utilization that yes.But, develop a new breed and take the time in 5～10 years at least usually, cycle is long, have high input, therefore, before new varieties are bred or in the breeding process, choose suitable tame pig variety, take rational hybrid combination, the wild hybridized pig of Development and Production man can be in time, to greatest extent wild boar is developed.
The wild hybridized pig of family is different from tame pig, the likeness in form wild boar, and habit is between tame pig and wild boar, if tame pig variety is suitable, hybrid combination is reasonable, the tame wild hybridized pig of producing just can have the two-fold advantage of wild boar and tame pig.It had both kept wild boar lean meat percentage height, adaptable advantage, overcome again wild sow only the time of the year when autumn changes into winter oestrus and the artificial house after shortcoming such as be difficult for oestrusing, can normal captive breeding, have the farrowing rate height, meat is good, premunition is strong, crude feed tolerance, easily raising, benefit advantages of higher.Its meat flavour deliciousness both had been different from the characteristics of tame pork fat too high levels, meat plumpness, mouthfeel difference, also coarse, the skin depth of the meat of rare pure wild boar, shortcoming that bilgy odour is heavy.The lean meat of wild boar is many, than tame pig high 6～8 percentage points, carcass lean meat percentage reaches as high as 85%, leaf fat is few, and back fat is thin, and fat content is low, and wherein essential fatty acid-linoleic content is 2 times～3 times of tame pig, be a kind of animal protein of better quality, this advantage and tame pig are hybridized utilization, the meat shearing force of its filial generation is little, has only 50%～60% of tame pig, tenderer than tame pork, simultaneously certain game is arranged again, mouthfeel is fine.
The production of tame wild hybridized pig at present, the coloured pig kind of many employings, it mainly is duroc, with the wild boar mating, the piglet that is born has hair color and the striped similar with wild boar, has also improved the growth rate of wild boar, but the tame wild hybridized pig that adopts this method to produce, muscle fat content is low, and meat is coarse, and edible quality is relatively poor.Also have the wild hybridized pig of part man to utilize wild boar and miniature pig such as the hybridization of fragrant pig to produce, this market pig meat is better, but growth rate is very slow, and economic benefit is lower.Therefore, the tame pig variety of seeking to suit is as the parent, and is very important in the production of the wild hybridized pig of being in.
In addition, in the production of the wild hybridized pig of being in, suitable wild boar blood lineage content is also extremely important.Difference according to the hybridization mode, the blood relationship of its contained wild boar in pure breed has multiple different purity such as 100%, 75%, 50%, 25%, according to raising situation and Market Feedback, be best with the hybridization wild boar of selecting 75%, 50% purity during breed, if too high its speed of production of purity is extremely slow, litter size is few, the difficult raising, purity be lower than aspect such as 25% hybridization wild boar profile, premunition, crude feed tolerance, lean meat percentage, nutrient component and tame pig comparatively approaching, raise be worth low.
The present invention has compared the heterosis, hybrid vigor of Different Cross Combinations through a large amount of research and experiment sieving, finds that the Huaihe River pig is that best tame wild hybridized pig is cultivated one of parent.The Huaihe River pig claims old Huaihe River pig again, is the ancient landrace that originate in Soil Development in Huaibei Plain, by hair black, bodily form compactness, mouth is long, four limbs are thick, with the nearly family of wild boar, are at present near one of landrace of wild boar, very approaching with wild boar in person at build, simple with the wild boar mating, become pregnant easily its offspring's well-grown, after introducing certain Du Luoke blood lineage, the growth of filial generation market pig rapidly.
Therefore, the present invention has proposed a kind of new tame wild hybridized pig production method first: with Du Luoke boar and the hybridization of Huaihe River pig sow, produce Du Huai binary sow, again with the wild boar boar as the terminal male parent, with the hybridization of Du Huai binary sow, produce and hybridize market pig.This method is not appeared in the newspapers and application in other place at present.
The hybridization market pig of adopting this method to produce, contain 50% wild boar blood lineage, 25% Huaihe River pig blood lineage, and 25% duroc blood lineage, fully utilized Huaihe River pig and the wild boar advantage aspect farrowing rate, lean meat percentage, meat, crude feed tolerance, premunition, introduce certain Du Luoke blood lineage simultaneously, improved growth rate, had following characteristics:
(1) figure and features is similar to wild boar: this hybridized pig is by hair black, and hair is long, and mouth is elongated and sharp and hard, and young pig has the pattern striped, and the back of growing up disappears mostly, and whole health body becomes sepia to grey black.
(2) crude feed tolerance, raise easily: this hybridized pig can search for food potato, Ipomoea batatas, dish leaf, various crops straw, tendril, leaf weeds, vinasse, multiple feeds such as vinegar is poor, sauce is poor, edible mushroom chaff, granulated slag, soybean curb residue, bagasse, feed resource is extensive and cheap, growing and fattening pigs can tolerate and contain 40%～60% roughage content in the manufactured feed, very easy raising.
(3) premunition is strong, the survival rate height: this hybridized pig resistance against diseases religion is strong, some common, frequently-occurring diseases of the pure family of less generation pig, and piglet survival ratio is also higher, is difficult for death, and is dead easily unlike domestic wild boar in pure breed piglet.
(4) reproductive performance is better, growth rate is very fast: the fertility of parent Du Huai binary sow is stronger, multiparity sow one tire can produce 12 above piglets, the hybridization market pig can reach more than 500 grams in daily gain during the live pig fattening, do not had significant difference with pure family pig, had higher raising and be worth.
(5) lean meat percentage height, the meat quality better: carcass lean meat percentage can reach more than 60%, is significantly higher than tame pig, and intramuscular fat content is more than 3.0%, fine and tender taste, meat flavour deliciousness.
