Description

The artificial propagation raising method of wild bamboo pig

The present invention relates to the method for letting animals feed, the artificial propagation raising method of particularly wild bamboo pig.

The bamboo pig has another name called the root pig, is one of the important wildlife in mountain area, the south of the River.Mammal.With bamboo, bamboo shoots, the leaf of bamboo, the bright rhizome of joint awns is staple food, does not have the drinking-water habit.It is underground to live in caves.Its build is sturdy, and maximum heavy 1.5 to 3.5 kilograms, and hair color is pitchy, and is glossy.The eye microtia is short, and pin is short and thick, and the front and back limb has five toes, and the belly hair color is greyish white, rare, and female bamboo pig has 3-4 to nipple, under the forward limb of its midriff a pair of nipple is arranged.Upper and lower two pairs of front tooth are thick hard sharp.Has the habit that cuts one another's throat and massacre external animal.Its life habit shows as to eat less daytime sleeps more, and night, food was vigorous.Happiness dark, nice and cool, dry, clean place life.Low temperature resistant and non-refractory is afraid of the sunlight direct projection especially.When the sunlight direct projection, environmental temperature shows as few food or food refusal greater than more than 38 ℃ the time, and belly is slept up, and disturbance is uneasy, and is dead after half an hour approximately.Temperature is crossed when hanging down, and shows as an abdomen and tightens, and the uneasiness of creeping constantly pipes.Suitable growth temperature is 8-28 ℃.Its meat of bamboo pig contains rich in protein, nutriments such as fat, multivitamin and calcium, phosphorus, iron, zinc, and its fur is tough and tensile fine and closely woven, can be processed into high-grade fur coat.Have the title of mountain delicacy.Have higher economic value and medical value.Because the bamboo pig belongs to wildlife, rely on natural propagation, growth, manual capture can only be done of short duration raising, is not suitable for commercialization production.

The object of the present invention is to provide the artificial propagation raising method of a kind of wild bamboo pig.In order to fully developing these Animal resources.

Realization of the present invention is by selecting breeding the oestrus of correct evaluation bamboo pig; divide pedigree hybridization pairing; the method of continuous composite breeding is carried out artificial propagation, is undertaken manually feeding raising by its life habit and the characteristics of searching for food, thereby reaches the purpose of large-scale artificial propagating and breeding.

Examination is supported to observe and shown: the breeding of bamboo pig has certain periodicity and seasonality.The annual breeding of a female bamboo pig triplet reaches sexual maturity after 10 monthly ages of being born by the young bamboo pig moon.To be that oestrusing of bamboo pig is prosperous sweep season for general spring, summer, Qiu Sanji.2-4 oestrous cycle generally can appear each mating season, and each 15-20 days at interval, each estrus duration 1-3 days.Its external genital of female bamboo pig in oestrus changes can be divided into for three phases: show as vaginal orifice and see swelling slightly early stage, smooth mellow and full, is white powder; It is gradually big to show as vaginal orifice swelling mid-term, and labia turns up, moistening, is pink or the flush look; The later stage performance is similar to early stage, sees drying slightly, is aubergine.The highest with mating in mid-term conception rate.Determine that female bamboo pig enters oestrus and also can show and differentiate by observing the examination feelings, the female bamboo pig that enters oestrus, movable frequent, send " cluck, cluck " cry every now and then, be very willing in the behavior near public bamboo pig, there is not the resistance performance, excitement is socialized.On the contrary, the relatively poor female bamboo pig that do not oestrus or oestrus is then refused public bamboo pig and goes into its cage house, sends to shout to frighten shriek, even hostile act such as baits.Above-mentioned showing, identify whether female bamboo pig enters oestrus, can confirm by the three phase variation characteristics of female bamboo pig genitalia and the method for observation examination feelings performance.

According to the growth and development state of bamboo pig, from young bamboo pig birth, generally reaching property is looked familiar after 9,10 monthly ages.At this moment, public bamboo pig genitalia feature shows as testis and increases, and is exposed between two hind legs, and scrotum is relaxed and comfortable sagging, and is flexible, and body weight is more than 1 kilogram.Female bamboo pig begins to occur periodically oestrusing performance, and therefore, apolegamy is planted should select for use greater than the sexually matured bamboo pig that reaches more than 10 ages and bred.With 11 monthly ages be the best.

For the purpose that reaches the purification complexification and improve the breed, apolegamy is kind appropriate to the occasion select that farrowing is many, to protect that son's property is strong, the offspring grows fast and disposition the male and female bamboo pig of docility give over to kind of a usefulness, to per generation male and female bamboo pig write the trade mark, set up pedigree, the difference pedigree is hybridized pairing.

Breeding test shows, identifies inaccurately in oestrus, and it is improper to put the prescription with ingredients even in number method, male and female bamboo pig is very easily taken place bait mutually.Force the consequence of mating to make the nonpregnant rate height of breeding, be difficult for being impregnated.Therefore, the apolegamy kind should implement put idol in the mid-term that female bamboo pig oestruses, and (putting idol promptly puts male and female bamboo pig together artificially, finish mating with short its), in order to improve conception rate, usually adopt composite continuously during breeding, promptly in an oestrous cycle, the single drylot feeding of every pair of bamboo pig was supported 3-7 days, carry out repeatedly mating of freedom.

After female bamboo pig breeding, the pregnancy duration is about 60 days, and expiration is childbirth at once, approximately special continuous 2-4 hour of farrowing process.Elder generation's output head, health lands subsequently, and general tire only produces 2-6, just before giving birth must single drylot feeding support with female bamboo pig in postpartum, to prevent other bamboo pig injury piglet.The newborn piglet body weight is the 8-15 gram only, and the long 6-8 of body centimetre, whole body does not have hair, with one's eyes tight shut.Begin behind 15 ages in days to become mildewed and search for food.

Bamboo swine rearing management, postnatal young bamboo pig generally can divide nest independently to raise with female bamboo pig behind 30 ages in days, and castrating removal ovary and testis after 2 monthly ages are to impel its growth.According to the habit of growth of bamboo pig, single house number of animals raised limit 10 with interior be one group, can set up separately in each single house and raise the same number of nest and give up.Limit raising male and female bamboo pig is a pair of in each single house.The construction of breeding cage house should be chosen in the place of cool place, drying, cleaning.Simple cage house can add that greater than 70 centimetres Porcelain Jar or waste oil bucket laying material makes greater than 40 centimetres, the degree of depth with diameter.Breeding scale then should adopt artificial the construction.

Because the bamboo pig does not have the drinking-water habit, therefore the required moisture content that earns a bare living, should note the moisture deal in the feed all by taking in from feed.The bamboo pig feed mainly is a plant feed, comprises grain trough, fruits and vegetables feed, woody section grass roots, stem, bamboo by product etc.Wide material sources and enriching.Grain trough such as corn, paddy, Ipomoea batatas etc. generally account for the 50-60% of bamboo swine rations; Fruits and vegetables class feed such as dish stem, carrot, good potato, sugarcane, water chestnut etc.; Grass roots stem, and bamboo class feed as grass stalk, corn straw, sorghum rod, soybean bar, Ipomoea batatas rattan etc., and bamboo shoots, the leaf of bamboo etc., also can be equipped with chicken commonly used, duck use pellet, feeding can divide early, middle and late three times hello raise.

Because the bamboo pig belongs to wild troglobite, in feeding and management, accomplish the environment peace and quiet, the food solemn silence of throwing something and feeding is latent worn-out, particularly lactation female bamboo pig, environmental stimulus easily causes abandoning the son, stings young and eats the son and wait abnormal behaviour.To prevent that also public bamboo pig and other female bamboo pig from entering in the female bamboo pig house of lactation, in case the cannibalisation young baby.

The premunition of bamboo pig is stronger, but propagates artificially, also disease can not take place at that time in weather sweltering heat or feeding and management, therefore is also noted that the preventing and controlling of carrying out eqpidemic disease in conjunction with the frequently-occurring disease feature of bamboo pig.

Economic implications of the present invention is to develop this Animal resources, to make full use of its economic worth and medical value by wild bamboo pig being realized the artificial propagation raising become wild into domestic.
