Abstract
The invention discloses a handling method for estrus synchronization of yaks. The handling method includes: organizing yak groups with the estrus synchronization; one month before the estrus synchronization, supplementarily feeding the organized yak groups with the estrus synchronization on a microelement of salt licks, wherein the supplementary feeding amount of each yak ranges from 50g to 80g per day; subjecting the female yak groups to intramuscular injection of Vitamin AD with the injection volume of 5ml per yak; placing CIDR in female yaks with a special bolt discharge device; on the 8th day after the CIDR is placed, subjecting the yak groups to injection of cloprostenol of PG, wherein the injection volume ranges from 0.2mg to 0.4mg per yak; on the 3rd day after injection of the PG, taking out the CIDR from the yak groups; subjecting the yaks with the estrus synchronization and teasing male yaks to group feeding, taking mounting behaviors which are stably received from the male yaks or other yaks as estrus characteristics, and performing twice semen deposition on each yak. By the handling method, matching rate and pregnancy rate of the yaks can be increased, mating period can be shortened, infertility can be reduced, reproductive rate can be improved, labor and resource consumption are reduced, the artificial insemination technology can be carried out beneficially on the yaks, and organization of reproduction can be facilitated.
Description
Technical field
The invention belongs to livestock-raising technical field, relate to a kind of processing method of yak estrus synchronization.
Background technology
Synchronization of Estrus is one of important Reproductive manipulation technology during modern farming enterprise's is produced, it is to utilize some hormone preparation to control artificially and adjust the estrus cycle of a group female animal, make they concentrate oestrus, concentrate breeding, concentrate gestation, concentrate childbirth, be conducive to organize production and administration.In addition, synchronization of Estrus also helps the further popularization of technology of artificial insemination, is also the important step of embryo transfer work simultaneously.Synchronization of Estrus is extensive use in reproduction of domesti animals, and has obtained certain effect.But to breeding the yak in the high and cold few oxygen environment in height above sea level 3000m left and right, existing synchronization of Estrus is still in the exploratory stage, and further research will provide theory and technical support for production application.
Yak is typical seasonal oestrus animal, psychro-environment is had to very strong adaptability, form its special breeding physiology phenomenon, at calving spontaneous estrus common non-estrus in season then, cause the even reproductive patterns of 3 years 1 tires of 2 years 1 tires, generally the area about height above sea level 3000m, the sexual season of female yak is in 6～November, focusing mostly in 7～JIUYUE, account for more than 70%, is oestrus the most vigorous period (Zhang Rongchang 1989).In addition, body weight, age, nutriture, external environment and Reproductive State etc. also have certain influence to its effect of oestrusing.Although scientific research personnel has all over the world done much work (Shao Binquan, 1984,1986 on Estrus Synchronization Techniques in Yak; Yang Tingyou, 1984; Liu Zhiyao, 1985; Shi Weiwen etc., 1985; Zhao Ping Yao etc., 1994A.Magash etc., 1997; M.Davaa etc., 2000), also having made some progress, but be applied to production, its effect is also undesirable.
Summary of the invention
The object of the invention is to overcome the defect that above-mentioned technology exists, a kind of processing method of yak estrus synchronization is provided.The method comprises estrus synchronization yak group's tissue, Estrus synchronization program, oestrus and identify and the step such as programmed breeding, utilize the present invention, can improve yak is joined rate, conception rate, shortening service period, is reduced infertile, raising breeding potential, reduce manpower and materials consumption, be conducive to again technology of artificial insemination carrying out on yak, be convenient to tissue and produce.Its concrete technical scheme is:
A processing method for yak estrus synchronization, comprises the following steps:
S1, set up and intend the yak group that carries out estrus synchronization, require cow health anosis, especially can not have reproductive diseases, the age is between 3.0-8.0 year, after calving more than 2 months, and the medium growth of livestock;
S2, carrying out before estrus synchronization work January, the estrus synchronization cows of step S1 tissue are carried out to trace element block salt supplementary feeding, a head all day supplementary feeding amount is 50-80g;
S3, any a day of yak estrus cycle, to the cow group intramuscular injection vitamin AD of step S2, injection volume is 5ml/ head;
S4, the special bolt device of putting for the cow of step S3 is placed to CIDR;
S5, putting after CIDR the 8th day, the cow group of step S4 is injected to Cloprostenol PG, injection volume is every yak 0.2～0.4mg;
S6, in injection after PG the 3rd day, take out the CIDR of step S5 cows;
The situation of oestrusing of observing step S6 cows for 24～48 hours after S7, taking-up CIDR; by estrus synchronization yak and the gregarious raising of the public yak of examination feelings; be the feature of oestrusing to the stable mounting that receives public yak or other yak; accept mounting and after 10 hours, carry out artificial insemination for the first time; after 20 hours, carry out artificial insemination for the second time, every yak carries out twice semen deposition.
Compared with prior art, beneficial effect of the present invention is: from estrus synchronization yak group's tissue, Estrus synchronization program, the aspects such as evaluation and programmed breeding of oestrusing consider the yak estrus synchronization rate that improves, its method characteristic, the one, being fed and injected vitamin AD by trace element block salt guarantees yak nutritional need and reproductive system health requirements, the 2nd, artificially regulate estrus cycle of yak by reproductive hormone, utilize the exogenous hormone such as CIDR and PG, stimulate yak gonad, cause corpus luteum growth and decline, reach the object that regulates the yak estrus cycle, the combination utilization of CIDR and PG, make yak estrus synchronization rate high, corpus luteum forms well.Utilize this present invention, can improve yak and be joined rate, conception rate, shortening service period, reduce infertile, raising breeding potential, reduce manpower and materials consumption, be conducive to again technology of artificial insemination carrying out on yak, be convenient to tissue and produce.
