今天我们主要研究兔子的发情观察和繁殖技术,看看如何让兔子顺利繁殖。下面来从家兔发情观察及饲养技术要点这一内容讲起吧。
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、发情观察
1. Oestrus observation
长毛兔母兔发情行为主要表现为好动、好动,喜欢跑跳、刨爪、踩地、食欲不振、少食,俗称“致圆圈”。性欲强的雌兔会和雄兔调情并爬过去,甚至会爬过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.
雄兔追爬时,发情的雌兔后躯上提,迎接雄兔的交配动作,表现出愿意接受交配的姿态。上述发情表现一般持续3~4天。一般根据养殖兔的存栏数量、生产性能、季节和饲料供应情况,综合考虑兔的养殖时间和数量,制定详细的养殖计划是保证肉兔生产取得良好经济效益的基础。
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.育种技术
2. breeding technology
1.人工辅助育种。人工辅助育种可以有计划的选配,避免近亲繁殖和随机繁殖;可合理安排公兔的配种时间,延长配种兔的配种期。使用年限;能有效防止疾病的传播。一般的养兔场(户)大多采用这种科学的养殖方式。如果母兔发情不接受交配,可采取强制辅助繁殖措施。即操作者用一只手托住母兔的耳朵和颈部皮肤固定母兔,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,露出外阴,并允许雄性兔子爬过去交配。
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。长毛兔人工授精的很大优点是可以充分利用优秀的雄性家兔,从而加快遗传进程,提高家兔种群质量,迅速推广好品种。家兔人工授精成败的关键,一是精液质量好,二是刺激雌兔排卵,三是授精部位准确。授精时,必须将授精器插入阴道壁后部,深度6~7厘米,穿过尿道,将精液注入两个宫颈口附近,使精子进入两个子宫。从宫颈。要想在兔子生产上取得更好的成绩,制定合理的养殖计划是非常有必要的。
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.
