Abstract
The invention discloses a method for improving the reproductive performance of sows. The method for improving the reproductive performance of sows comprises mixing N-carbamylglutamate with auxiliary materials so as to prepare feed containing 0.01-0.04wt% of N-carbamylglutamate for feeding the sows within 1-28 days after the mating. According to the method, the reproductive performance of sows can be improved significantly; specifically, the average total piglet number of each pregnancy, the average surviving piglet number of each pregnancy and the average healthy piglet number are increased; and compared with the existing method, the same or nearly the same effect is reached, and at the same time the feeding time and the feeding quantity are reduced, and the cost is reduced; and the feeding is performed immediately after the sows mate, and is convenient for the operation in practice.
Description
Technical field
The invention belongs to the technical field of animal feed, be specifically related to a kind of method that improves sow reproductive performance.
Background technology
Content in arginine Zhu soma albumen is only second to leucine, and in the whole process of piglet embryonic development, arginine is all the abundantest nitrogen carriers of body protein all the time in addition, and prompting arginine is quantitatively for the significance of pregnant sow; Except participating in the deposition of body protein, arginine is also being brought into play important nutrition physiology effect by its metabolite as nitric oxide and polyamines in sow body, also can be used as the sercretogogue of insulin in pregnant sow body simultaneously, point out its significance to regulation and control pregnant sow breeding physiology.Arginine has obtained many-sided checking to the action effect of pregnant sow, has obvious improvement effect, but add cost more than 800 yuan/ton to improving reproduction performance of gestation sow, is unfavorable for promoting.
N-carbamylglutamic acid can be used as the activation that metabolic activation agent participates in dihydropyrrol-5-carboxylic acid synzyme and carbamyl phosphate synthetase I, promote glutamine or proline synthesis citrulling, and then promote arginic synthesizing, by arginine, be used for improving sow reproductive performance.Patent CN201010227184 provides N-carbamylglutamic acid within 14 ~ 114 days, in daily ration, to add 0.05 ~ 0.2% report at sow gestation, in addition also have at present 3 pieces about the consumption of N-carbamylglutamic acid and the bibliographical information of operational phase, Jiang Xuemei etc. (2011, diet adds L-arginine or the impact of N-carbamylglutamic acid on multiparity sow reproductive performance and blood parameters, " Animal nutrition journal ", 23(7): 1185 ~ 1193) provide N-carbamylglutamic acid within 1 ~ 114 day, in daily ration, to add 0.05% report at sow gestation, poplar equality (2011, diet adds L-arginine or the impact of N-carbamylglutamic acid on infection PRRSV reproduction performance of gestation sow and immunologic function, " Animal nutrition journal ", 23(8): 1351 ~ 1360) provide N-carbamylglutamic acid within 30 ~ 90 days, in daily ration, to add 0.05% report at sow gestation, Yue Longyao and a watchtower bodyguard man of virtue and ability (2009, sow daily ration later stage of pregnancy adds the impact of N-carbamylglutamic acid (NCG) on reproductive performance, " Shandong animal and veterinary ", supplementary issue in 2009, 1 ~ 3) provide N-carbamylglutamic acid within 85 ~ 114 days, in daily ration, to add 1% report at sow gestation.Though method can improve all total young number and tire young numbers of all living of tire described in above-mentioned patent and first piece of document, life cycle is long, high cost; Described in rear two pieces of documents method except the cycle is long, cost high, only can improve the tire young number of all living, on tire all total young number without impact.Generally, with patent CN201010227184, provide at sow gestation, within 14 ~ 114 days, in daily ration, to add the method cost performance of 0.05%N-carbamylglutamic acid the highest.Not yet have at present that a kind of cycle is shorter, cost is lower and the method for the raising sow reproductive performance of better effects if report.
Summary of the invention
The object of the invention is to, the rule that forms and survive according to sow gestation phase embryo, overcomes the deficiencies in the prior art, and a kind of method that improves sow reproductive performance is provided.Method cost of the present invention is low, and the cycle is short, easy to use, and practical application is had to very large meaning.
Above-mentioned purpose of the present invention is achieved by following technical solution:
Improve a method for sow reproductive performance, N-carbamylglutamic acid is mixed with auxiliary material, forming a kind of N-carbamylglutamic acid content is the feed of 0.01 ~ 0.04 % by weight, sow is fed in 1 ~ 28 day after insemination of sows.After 28 days, feed routinely provides, in the feed after 28 days, not containing N-carbamylglutamic acid.
The preparation method of described feed, for N-carbamylglutamic acid is added in auxiliary material, fully stirs and makes in agitator.
Described auxiliary material is the conventional auxiliary material in this area, can, from buying and obtain on the market, effect of the present invention not had to too much influence.As a kind of preferred version, described auxiliary material is the mixture in B B-complex, mineral element additive, corn, wheat, dregs of beans, wheat bran, rice bran meal, inferior powder, stone flour, calcium monohydrogen phosphate, glauber salt, salt.
As a kind of preferred version, the amount of providing of described feed is that every pig is supplied 1.5 ~ 2.5kg every day.
In Swine Production, improving sow reproductive performance key constraints is that sow gestation phase embryo's percent of loss is high.Within after insemination of sows initial 28 days, be that embryo forms and survives the most key period, most of embryo's losses are exactly to occur during this period of time, therefore inventor raises and has done further investigation for the sow in this period, find during this period of time, add a small amount of N-carbamylglutamic acid and can significantly reduce embryo's percent of loss, reach with the identical or approaching effect of existing method in, shorten feeding time and scale of feeding, reduce costs.
Compared with prior art, the present invention has following beneficial effect:
Method of the present invention can improve sow reproductive performance significantly, total be exactly increase specifically all young number and tire young numbers of all living of breeding parturition rate, tire, and compared with the existing methods, it is when significantly improving sow reproductive performance, shorten feeding time and scale of feeding, reduce costs; After insemination of sows, feed, the operation of being more convenient in actual production.
