宠物狗如何配种？英文双语对照

配种适期：较正确地掌握配种期，是提高受胎率的关键。其推算方法是，确认母狗的阴门有明显肿胀、潮红或见第一滴血时作为第1天，初产狗一般在第11~13天进行首次交配；经产狗在第9~11天进行首次交配。母狗的年龄每增加二岁或胎次每增加二窝，首次的交配应前移1天。有的高产

　　母狗经多次产仔历后，发情5天其阴道就停止出血，在第6或第7天配种即可受孕。如主人未发现阴道排血的开始日期，也可根据阴道分泌物的颜色变化进行确定配种的最佳日期。当阴道分泌物的颜色由红变为稻草黄色后的2~3天，即可进行交配，此时，母狗的阴唇柔软，垂直状态的阴道前庭已变得平直，便于公狗阴茎的插入。然而，有少数的母狗在发情前期和发情期不出现阴道排血，还有个别母狗的血样分泌物可持续至发情期，或延续到发情后期的若干天，这样，当然不能靠观察阴道出血与否来确定母狗的配种日期，如遇这种情况，可用公狗进行试情，母狗愿意接受公狗交配后的1~3天，就是最佳配种期。

　　配种方法：根据饲养管理的条件、水平和繁殖目的的不同，可采用多种不同的配种方法。现将主要的配种方法介绍如下：

　　①人工辅助交配：平时就将公、母狗严格隔离进行饲养、在母狗发情的配种最适期，选出优良公狗。在人的控制下使其进行交配，交配后再立即将公、母狗分开。

　　⑦单次配种：母狗进入发情期(性欲出现)的第2天，用一条公狗配一次，或用一条公狗的精液进行人工授精一次。这是自己没有种公狗，配种受到某些条件限制进行的单次配种。

　　③多次配种：母狗发情的配种最适期，第一天交配一次，然后再每隔24小时交配一次。一个发情期内一般可复配2~3次。

　　④双重交配：在母狗的发情期内，用不同品种的两条公狗或同品种的两条公狗，间隔24小时先后各备配种一次。这种配种方式可提高繁殖率，并可增强后代的生命力。

　　⑤重复交配：在发情期内先后配种2次。一般在发情期的第二天配第一次，再间隔48小时后用同—种公狗配第二次。这样，可增加母狗的受精机会，提高受胎率，还能使主人掌握后代的血统。

　　⑧围栏交配：是指公、母狗在平时进行隔离饲养，配种时，却在围栏内放人一条母狗，让特定的公狗与之交配。

　　⑦分群交配：是在配种季节，将一条或数条经过选育的公狗放入一定数量的母狗群中饲养，任其自由交配。这可提高配种的成功率和受胎率。

　　⑧人工受精：是用人工方法采取公狗的精液后，再经检查与处理后，用器械注入发情母狗的生殖道内，使其受孕。此方法有助于提高受胎率．充分发挥优良公狗的配种效能，增加公狗的配种比例，并可减少公狗的饲养费用，还可克服因公、母狗个体大小悬殊而带来的交配困难，此外，还可避免生殖系统的传染病、加速狗的育种进程。群体饲养较适用于此种配种方法。

　　配种时应注意的问题：处女狗在初次交配时，虽有强烈的性欲，但对公狗的爬跨和交配常会出现恐惧和不安，所以对处女狗的交配，应选择有交配经验的公狗。如母狗过于惊惧不安，也可予以人工辅助保定母狗，再完成交配过程。

　　在这里应特别提醒爱犬主人，公犬与母犬交配时，阴茎插入阴道几秒钟后便开始射精，随后公犬从母犬背上爬下，生殖器官不能分离而呈尾对尾的姿势。这种锁结状态，大约持续20~45分钟。才会自行解脱，因此有人看见其母犬被公犬爬跨过或母犬跑失5—10分钟后才找到，就非常担心母大已经和公犬交配上了，若知道这个常识，你就尽可以放心了。

Hybridization is comfortable period: Master hybridization period correctly, it is the key that raises be impregnated rate. Its are computative the method is, the vaginal orifice that affirms bitch has apparent strut, tide red or the 1st day serves as when seeing the first blood, the dog is produced to undertake in 11~13 day commonly first first copulatory; Undertake in 9~11 day via producing a dog first copulatory. Every raise the age of bitch 2 years old or embryo second every increase 2 broods, first copulatory should reach 1 day. Some high yield

Bitch classics for many times after kitten all previous, 5 days of its vaginas stop oestrus haemorrhage, in the 6th or the 7th day of hybridization can become pregnant. If host did not discover what the vagina discharges blood to begin date, also can undertake fixing the optimal date of hybridization according to the color change of vaginal secretion. The color when vaginal secretion by red turn into the 2~3 day after straw yellow, can undertake copulatory, right now, the labium of bitch is soft, the vaginal vestibule of verticality already became flat, facilitate the insertion of fair dog penis. However, the bitch that has a few does not appear in oestrus early days and rut the vagina discharges blood, the hematic sample secretion that still has individual bitch can last to rut, or a certain number of days that continue to oestrus later period, such, cannot rely on to observe the vagina bleeds to fixed the hybridization date of bitch of course, if meet this kind of condition, can undertake trying affection with fair dog, bitch is willing to accept the 1~3 day after fair dog is copulatory, it is optimal hybridization period.

Hybridization method: Of the condition according to raising management, level and progenitive purpose different, can use a variety of different hybridization methods. Introduce main hybridization method as follows now:

① assists artificially copulatory: Keep apart strictly with respect to will fair, bitch at ordinary times undertake raising, the hybridization in bitch oestrus is the most comfortable period, single out admirable fair dog. Make below the person's control its undertake copulatory, copulatory hind part fair, bitch instantly again.

⑦ is odd second hybridization: Bitch enters rut (sexual desire appears) the 2nd day, with fair dog matchs, or the seminal fluid that uses a fair dog enters pedestrian labour insemination. This is this does not have kind of fair dog, the sheet that hybridization is undertaken by certain condition limitation second hybridization.

③ for many times hybridization: The hybridization of bitch oestrus is the most comfortable period, the first day copulatory, next again every other 24 hours copulatory one. Inside a rut general but answer match 2~3 second.

④ is double and copulatory: Inside the rut of bitch, two when use different variety fair dogs or two when be the same as breed fair dogs, interval has 24 hours each early or late hybridization. Means of this kind of hybridization can raise progenitive rate, can enhance unborn vitality.

⑤ weighs reestablish diplomatic relations to match: Inside rut early or late hybridization 2. Be in commonly of rut match first time the following day, again removed use after 48 hours with, kind fair dog matchs the 2nd times. Such, can increase the be fertilized chance of bitch, raise be impregnated rate, return the blood relationship that can make host control unborn.

⑧ crawl is copulatory: It is to show fair, bitch is undertaking keeping apart raising at ordinary times, when hybridization, put a person inside crawl however a bitch, let specific fair dog to it copulatory.

⑦ hive off is copulatory: Be in hybridization season, will or several fair dogs that pass seed selection put a certain quantity of nut raise in doggery, hold the post of its freedom is copulatory. This can raise the successful rate of hybridization and be impregnated rate.

⑧ artificial be fertilized: It is the seminal fluid that takes fair dog with artificial method hind, again after classics examination and processing, inside the reproductive method that uses bitch of appliance infuse oestrus, make its become pregnant. This method conduces to raise be impregnated rate. Sufficient play is good the hybridization efficiency of fair dog, increase the hybridization proportion of fair dog, can reduce fair dog raise cost, still can overcome on business, bitch individual magnitude wide gap and brought copulatory difficulty, in addition, return the infection that can prevent reproductive system, breeding process that accelerates a dog. The group is raised relatively apply to method of this kind of hybridization.

Watchful problem answers when hybridization: Maiden dog is in copulatory the first time when, although have strong sexual desire, but to fair dog climb cross and occurrence fear of copulatory regular meeting and uneasiness, be opposite so of maiden dog copulatory, should choose to have the fair dog of copulatory experience. Be like bitch too Jing dread is disturbed, also can give bitch of artificial and auxiliary Baoding, complete copulatory process again.

Answer here special remind love the dog is master, when fair dog and mother dog are copulatory, ejaculation begins after the penis inserts the vagina a few seconds, subsequently fair dog carries climb down on the back from mother dog, genital official is irresolvable and assume remaining part the pose to end. This kind locks up knot condition, last about 20~45 minute. Ability can free oneself by oneself, because this somebody sees its mother dog is climbed to had been crossed by fair dog or mother dog runs,break 5, the ability after 10 minutes is found, very afraid mother has been mixed greatly fair dog is copulatory went up, if know this common sense, you all can be at ease.
