Description
Technical field
The invention belongs to the sow feed technical field, be specifically related to the special-purpose concentrate feed of a kind of nonpregnant phase sow, this concentrate feed can impel nonpregnant sows early to oestrus, ovulate more.
Background technology
Whole breeding cycle of sow in (pregnancy～childbirth～lactation～from breast～breeding～pregnancy) each stage is a process all linked with one another; Nutrient canal is before comprehended all stages afterwards that have influence on, and therefore must all provide best nutrition to rise to reproductive performance the highest in each stage.Compare with sow gestation, lactation; The nutrition of nonpregnant phase of sow never obtains due attention; In the actual production because of lacking the special feed product of nonpregnant phase of sow; Cause generally occurring out of heat or delays of oestrusing in sow wean back, join infertile repeatly and litter size problem such as less, become a great problem of current puzzlement pig industry.
Nonpregnant sows is meant and reaches the of the right age replacement gilt of planting of not mixing as yet of breeding that perhaps the milking sow of planting (it comprises wean sow, the sow of miscarrying, returns feelings sow, long-term sow out of heat) is mixed in piggy (claiming the seedling pig again) wean back until oestrusing.In Swine Production, rationally raise nonpregnant sows, it is normally oestrused and arrange healthy and strong ovum more, improve breeding rate and conception rate after its breeding, make that voluminous piglet is to improve one of the key of economic benefit of raising pigs among every sow 1 year.
Four kinds of hormones (are follicle-stimulating hormone FSH, luteotropin LH, estrogen E in the equal acceptor of the reproductive behavior in sow postweaning estrus, ovulation and later stage
2, progestational hormone P
4) manipulation of secretion level, various hormonal readinesses present dynamic rule, so as to be the completion of different phase physiology task create suitable in environment, non-suitable period (as weaning the back after 1～2 day or 7 days), oestrusing to influence the parturition rate in later stage.The mechanism of follicular development, maturation and ovulation is: FSH concentration raises, and increases ovarian follicle and raises quantity; The reduction of FSH concentration, LH and E
2Concentration raises, dominant follicle advantageization, maturation; E
2Grow rapidly with the collaborative ovarian follicle that promotes of LH, until ovulation.
In the actual production, the normal measure of adopting of sow with functions of promoting sexual maturity is: use follicle-stimulating hormone and luteotropin, or with pregnant mare serum or human chorionic gonadtropin (SCG), or synthetic hormone PG600 etc.Recover the ovary function though above-mentioned measure can be played, promote the ovarian follicle normal development, impel the effect of oestrusing and ovulating, also have some defectives: more expensive like price; Can only individually handle; Can not shorten blanking time from wean to the breeding of oestrusing once more; Can not improve the birth quality of newborn piglet etc.

The wean sow method of feeding: if when using the agent of feed for nursing sow of our company, the effect of promoting the sexual maturity of the preceding 7 days concentrate feeds of the present invention of feeding of weaning is the same with the effect that wean began to feed the same day, and suggestion is weaned and begun to feed the same day; If use the agent of feed for nursing sow of non-our company, fed in preceding 7 days (in order to make its adaptation for the sow laundering period) of advising weaning.The nonpregnant sows that aligns normal off milk is fed need at least 4 days.
Mentality of designing of the present invention:
The first, be intended to regulate neuroendocrine system.
Add compound vitamin, probiotics, V
EAnd V
CDeng; Through its antioxidant radical active material that contains; Like Mongolian oak skin ketone-3-0 glucopyranose (quercimentin), Mongolian oak skin ketone (flavonoids), inositol, phytosterol etc., regulate sow breeding hormonal readiness, repair the sow reproductive system; Promote the continuous release of estrogen and follicle-stimulating hormone also to grow steadily, thus shorten the blanking time of wean to the breeding of oestrusing and clearly oestrus, promote to ovulate, raising conception rate and parturition rate etc.Tradition genital regulating product not only is difficult to absorb in enteron aisle, and unstable, easily decomposition failure.The probiotics that is adopted among the present invention is very stable in enteron aisle, is not easy to be degraded by digestive ferment.
The second, be intended to supply with prescribing adequate nutrition.
Energy: energy is higher than agent of feed for nursing sow, and energy supply source is starch, fat and glucose (effect of glucose in concentrate feed of the present invention provides energy, but not is used as sweetener).Though energy is not a kind of tangible nutriment, it is contained in three major nutrients such as protein, carbohydrate, fat, is the heating power basis of all vital movements.The energy undersupply can suppress the pulse generating system of jenny gonadotropin-releasing hormone (GRH) (GnRH) and the release of sex hormone; Cause supporting that the promoting sexual gland hormone and the gonadal hormone of follicular development are obviously not enough, thereby influence growing and the mature ovulation of egg mother cell of jenny ovarian follicle.Energy level in the daily ration influences the expression of gonadotropin receptor on the ovary, thereby is having a strong impact on the growth of ovarian follicle on the ovary, causes the variation of ovulation rate and litter size.Influence in the follicular development process of jenny through the activity that changes hypothalamic-pituitary-ovarian axis in the dietary digestibility of energy trophic factor, metabolism signals such as insulin, leptin and insulin-like growth factor-play important mediation.In addition, insulin influences follicular development through locking that reduces ovarian follicle on the ovary and the quantity that increases the ovarian follicle that possibly grow the ovulation stage.
Probiotics: also can be described as " the genital regulating factor "; Through probio symbiosis cultivation and classification composite fermentation technology; Make and be rich in the various active natural products in the product, can repair the reproductive system normal function fast, promote to breed the secretion of dam endogenous estrogen.Its main component of the used probiotics of the present invention is: beneficial microbes such as bacillus, Bacillus acidi lactici, photosynthetic bacteria and saccharomyces cerevisiae, its useful total viable count>=5 * 10
9/ g.
Protein and amino acid: protein level and agent of feed for nursing sow are approaching, but amino acid levels such as lysine, methionine, threonine are higher.Because of the gestational period, sow in lactation daily ration need methionine is 0.26%, and nonpregnant sows to need level be 0.34%, so the free methionine of extra interpolation.
Mineral matter: add trace elements such as selenium, chromium.Chromium is the essential composition of glucose tolerance factor (GTF), is used for improving ovulation rate through glucose tolerance factor.Glucose has increased insulin level and ovulation speed in the blood, and chromium and insulin act synergistically on cell membrane, makes more glucose get into ovary, thereby for ovulating energy is provided.Chromium further improves stimulation GnRH release LH and FSH again as the confactor of insulin.Simultaneously, chromium can also promote glycine, and amino acid such as serine and methionine get into cell and promote the synthetic of protein, and growing for ovum provides proteinogen.
Methionine and choline: methionine can promote follicular development and ovulation; Choline lacks can increase the weight of vitamin e deficiency, and causes oligo-ovulation, and farrowing is few.
Vitamin: add vitamin A, vitamin E, vitamin C and β～carrotene etc. with the driving factors of oestrusing.Vitamin E (having another name called tocopherol) is closely related with the reproductive capability of animal, has sexual gland, the development of ovary of promotion, facilitates effects such as becoming pregnant, prevent miscarriage.The E that is deficient in vitamin will cause reproductive capability disorderly, out of heat or delays of oestrusing, infertile, miscarriage, stillborn foetus even lose fecundity.Vitamin C: participate in the redox reaction in the body, matter is complete between the maintenance ovum, makes ovum healthy and strong.Beta carotene: having sound, the complete effect of protective epithelium tissue, is the important substance basis of mucosa-immune, and the growth of reproductive organs is had tangible influence.Nonpregnant sows vitamin E requirement is nearly 2.3 times of milking sow, and the beta carotene requirement is 50 times of milking sow, and the vitamin C milking sow does not need extra interpolation, and content need reach 500mg/kg in the nonpregnant sows daily ration.
Compare beneficial effect of the present invention with prior art:
1) through compound vitamin (containing active beneficial bacterium), probiotics, V
EAnd V
CCan be used as free radical scavenger Deng the antioxidant radical active material that contains; Remove excessive oxygen radical in the dam body; Change bacterial adhesion property, strengthen in alimentary canal the temporary transient velocity of discharge that combines, accelerates microbial toxin with harmful substance, effectively repair the sow reproductive system; Endogenous steroid hormone level is risen and stable and durable, improve ovulation quality, the early stage implantation rate of embryo and survival rate of embryo.
2) through forced for vitamins E nutrition, can promote sexual gland, the development of ovary, facilitate and become pregnant, prevent miscarriage; Forced for vitamins C nutrition is participated in the vivo oxidation reduction reaction and is kept matter integrality between ovum, makes ovum healthy and strong; Strengthen beta carotene nutrition, the protective epithelium tissue is sound, complete, is the important substance basis of mucosa-immune, and the growth of reproductive organs is had tangible influence; Strengthen methionine nutrition, promote follicular development and ovulation; Strengthen choline nutrition, with the vitamin E synergy, many ovulations.In addition, energy, proteinaceous nutrient level that concentrate feed of the present invention contains capacity are high, and for the growth of ovarian follicle provides basic substance, the energy of fast Absorption can influence the secretion of hypophysis weight and gonadal hormone, the quantity of increase ovarian follicle weight and large follicle.
3) pass through vitamin (A, E, C, beta carotene, folic acid, biotin) and organic trace element (chromium, selenium etc.) optimum organization, system regulation more tends to balance nutrition, meets nonpregnant stage sow physiology and nutritional need.
In a word, use the concentrate feed of the present invention nonpregnant sows of feeding, can safeguard the sow healthy reproduction, guarantee to continue the reproductive performance of high yield, solve the long-term difficult problem out of heat of replacement gilt; Sow rate of oestrusing in back 10 days of wean is reached more than 90%, greatly reduce the feelings rate of returning; Make every sow can arrange 2～3 pieces of ovum each oestrus, every sow year farrowing can increase more than 1.5 more.
