长毛兔繁殖的三个误区

一般在长毛兔生产的周期性变化下,一些养兔户为了尽快繁殖仔兔,往往走进繁殖误区,表现为以下三个方面。我们蒙阴长毛兔养殖厂家给大家介绍一下:
General under the periodical change of hares production, some rabbit to rabbit breeding boy as soon as possible, often into the propagation error, characterized by the following three aspects. We darkened hares breeding manufacturer to introduce you to:
一、配种过早。长毛兔的性成熟早于体成熟。小体型品系的兔3~4月龄就达到性成熟。而6月龄才接近体成熟;大体型品系的兔4~5月龄达到性成熟,8月龄时才接近体成熟。有些刚引种的养殖场、户为了在种兔销售形势好的时候,早繁殖早出售种兔,不到配种月龄就使种兔提早配种繁殖,结果因种兔营养水平和身体状况满足不了自身和胎儿生长发育的需要,造成妊娠母兔大量流产,或产下死胎、弱仔,母兔产后无乳或乳汁不足等情况,这样不但没有达到预期目的,反而使种兔身体受到损失,推迟了繁殖期。
A, breeding early. Hares of sexual maturity before maturity. Small size strains of rabbit 3 ~ 4 months reached sexual maturity. Mature and 6 months of age only close to the body; Large strain of rabbit 4 ~ 5 months to reach sexual maturity, 8 months when close to mature. Some introduction of farms and homes in the plasticine sales good times, early breeding and sale of plasticine, less than breeding months make plasticine early breeding and breeding, the results for the plasticine nutrition level and physical condition doesn't satisfy the need itself and fetal growth and development, causing huge abortion of pregnant mother rabbit, or gave birth, weak young mother rabbit postpartum without milk or milk shortage, etc., such not only there is no trick, made by the plasticine body loss, delay the breeding season.
二、比例失调。理论上1只种公兔可以负担8~10只母兔的配种任务,但实际上1只种公兔承担10只母兔的配种任务时,如实行复配,那么这只种公兔就要每天连续配种2次。如此长期频繁地使用,种公兔会因体质消耗过大而导致性欲减退、精液品质下降,受配母兔空怀率高,失去种用价值。
Second, the imbalance. In theory 1 kind of male rabbit can afford only 8 ~ 10 female rabbit breeding task, but is actually one kind of male rabbit, undertake the task of 10 female rabbit breeding, such as distribution, then it is the only kind of male rabbit breeding 2 consecutive times a day. So frequent use for a long time, a male rabbit can lead to loss of libido due to excessive physical consumption, quality decline of sperm, the mother rabbit just ratio is high, the loss of a value.
三、连续血配。在母兔产仔后2天内进行交配,使哺乳与妊娠时进行,使母兔在单位时间内生产出更多后代的繁殖方法即为血配。这种方法虽然可以迅速地繁殖后代,但不能连续使用,因为在血配时由于母兔吸收的营养物质一要维持自身的新陈代谢,二要产生乳汁哺育仔兔,三要供给胎儿生长的需要,而通常在一般饲养条件下,母兔吸收的营养物质满足不了这三个方面的需求,导致母兔体质消耗过大,身体衰竭,乳汁分泌不足;哺乳仔兔由于营养缺乏而体质弱、生长缓慢、死亡率高;所怀的胎儿生长发育缓慢,出生后体弱,成活率也低。
Three, continuous blood. Within 2 days after the mother rabbit breed mating, make with pregnancy, lactation mother rabbit in unit time the number of descendants an endogenous output breeding method for blood. Although this method can quickly reproduce, but can't use in a row, because when the blood distribution as a rabbit to absorb nutrients to sustain their own metabolism, second to produce milk feeding larvae rabbit, third, we need to supply the demands of fetal growth, and usually in the condition of feeding the mother rabbit to absorb nutrients can't satisfy the needs of the three aspects, lead to mother rabbit physical consumption is too big, physical failure, lack of milk secretion; Lactation rabbit physique weak due to a lack of nutrition, slow growth, high mortality; The baby fetal growth and development is slow, weak after birth, the survival rate is low.
