今天我們主要研究兔子的發(fā)情觀察和繁殖技術，看看如何讓兔子順利繁殖。下面來從家兔發(fā)情觀察及飼養(yǎng)技術要點這一內(nèi)容講起吧。

Today, we mainly study the estrus observation and reproduction technology of rabbits to see how to make rabbits reproduce smoothly. Let's start with the key points of rabbit oestrus observation and feeding techniques.

1、發(fā)情觀察

1. Oestrus observation

長毛兔母兔發(fā)情行為主要表現(xiàn)為好動、好動，喜歡跑跳、刨爪、踩地、食欲不振、少食，俗稱“致圓圈”。性欲強的雌兔會和雄兔調(diào)情并爬過去，甚會爬過自己的幼兔或其他雌兔。

The oestrus behavior of female long haired rabbits is mainly characterized by hyperactivity and hyperactivity, like running and jumping, pawing, stepping on the ground, loss of appetite and eating less, which is commonly known as "causing circles". Female rabbits with strong sexual desire will flirt with male rabbits and climb over, and even climb over their own young rabbits or other female rabbits.

雄兔追爬時，發(fā)情的雌兔后軀上提，迎接雄兔的交配動作，表現(xiàn)出愿意接受交配的姿態(tài)。上述發(fā)情表現(xiàn)一般持續(xù)3～4天。一般根據(jù)養(yǎng)殖兔的存欄數(shù)量、生產(chǎn)性能、季節(jié)和飼料供應情況，綜合考慮兔的養(yǎng)殖時間和數(shù)量，制定詳細的養(yǎng)殖計劃是保證肉兔生產(chǎn)取得良好經(jīng)濟效益的基礎。

When the male rabbit is chasing and crawling, the hindquarters of the estrous female rabbit are raised to meet the mating action of the male rabbit, showing a willing attitude to accept mating. The above oestrus usually lasts for 3 to 4 days. Generally, according to the number of breeding rabbits, production performance, season and feed supply, and comprehensively considering the breeding time and number of rabbits, the development of a detailed breeding plan is the basis for ensuring that meat rabbit production can achieve good economic benefits.

2.育種技術

1.人工輔助育種。人工輔助育種可以有計劃的選配，避免近親繁殖和隨機繁殖；可合理安排公兔的配種時間，延長配種兔的配種期。使用年限；能有效防止疾病的傳播。一般的養(yǎng)兔場（戶）大多采用這種科學的養(yǎng)殖方式。如果母兔發(fā)情不接受交配，可采取強制輔助繁殖措施。即操作者用一只手托住母兔的耳朵和頸部皮膚固定母兔，另一只手伸到母兔腹部下方，抬起臀部，用食指和中指固定尾巴，露出外陰，并允許雄性兔子爬過去交配。

1. artificial assisted breeding. Artificial assisted breeding can be selected in a planned way to avoid inbreeding and random breeding; The breeding time of male rabbits can be reasonably arranged to prolong the breeding period. Service life; It can effectively prevent the spread of disease. General rabbit farms (households) mostly adopt this scientific breeding method. If the female rabbit is in estrus and does not accept mating, compulsory assisted reproduction measures can be taken. That is, the operator holds the female rabbit's ear and neck skin with one hand to fix the female rabbit, extends the other hand to the lower part of the female rabbit's abdomen, raises the hips, fixes the tail with the index finger and middle finger to expose the vulva, and allows the male rabbit to climb over and mate.

2.人工授精。長毛兔人工授精的很大優(yōu)點是可以充分利用的雄性家兔，從而加快遺傳進程，提高家兔種群質(zhì)量，迅速推廣好品種。家兔人工授精成敗的關鍵，一是精液質(zhì)量好，二是刺激雌兔排卵，三是授精部位準確。授精時，必須將授精器插入陰道壁后部，深度6～7厘米，穿過尿道，將精液注入兩個宮頸口附近，使精子進入兩個子宮。從宮頸。要想在兔子生產(chǎn)上取得更好的成績，制定合理的養(yǎng)殖計劃是非常有必要的。

2. artificial insemination. The great advantage of artificial insemination of long hair rabbit is that it can make full use of excellent male rabbits, so as to speed up the genetic process, improve the quality of rabbit population, and quickly promote good varieties. The key to the success or failure of artificial insemination in rabbits lies in the quality of semen, the stimulation of ovulation in female rabbits and the accuracy of the insemination site. When inseminating, the inseminator must be inserted into the back of the vaginal wall, with a depth of 6 ~ 7 cm. It passes through the urethra and injects semen into the vicinity of the two cervical openings to make the sperm enter the two wombs. From the cervix. In order to achieve better results in rabbit production, it is very necessary to formulate a reasonable breeding plan.
