一般在長毛兔生產(chǎn)的周期性變化下，一些養(yǎng)兔戶為了盡快繁殖仔兔，往往走進(jìn)繁殖誤區(qū)，表現(xiàn)為以下三個(gè)方面。我們蒙陰長毛兔養(yǎng)殖廠家給大家介紹一下：
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、配種過早。長毛兔的性成熟早于體成熟。小體型品系的兔3~4月齡就達(dá)到性成熟。而6月齡才接近體成熟；大體型品系的兔4~5月齡達(dá)到性成熟，8月齡時(shí)才接近體成熟。有些剛引種的養(yǎng)殖場、戶為了在種兔銷售形勢好的時(shí)候，早繁殖早出售種兔，不到配種月齡就使種兔提早配種繁殖，結(jié)果因種兔營養(yǎng)水平和身體狀況滿足不了自身和胎兒生長發(fā)育的需要，造成妊娠母兔大量流產(chǎn)，或產(chǎn)下死胎、弱仔，母兔產(chǎn)后無乳或乳汁不足等情況，這樣不但沒有達(dá)到預(yù)期目的，反而使種兔身體受到損失，推遲了繁殖期。
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、比例失調(diào)。理論上1只種公兔可以負(fù)擔(dān)8~10只母兔的配種任務(wù)，但實(shí)際上1只種公兔承擔(dān)10只母兔的配種任務(wù)時(shí)，如實(shí)行復(fù)配，那么這只種公兔就要每天連續(xù)配種2次。如此長期頻繁地使用，種公兔會(huì)因體質(zhì)消耗過大而導(dǎo)致性欲減退、精液品質(zhì)下降，受配母兔空懷率高，失去種用價(jià)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、連續(xù)血配。在母兔產(chǎn)仔后2天內(nèi)進(jìn)行交配，使哺乳與妊娠時(shí)進(jìn)行，使母兔在單位時(shí)間內(nèi)生產(chǎn)出更多后代的繁殖方法即為血配。這種方法雖然可以迅速地繁殖后代，但不能連續(xù)使用，因?yàn)樵谘鋾r(shí)由于母兔吸收的營養(yǎng)物質(zhì)一要維持自身的新陳代謝，二要產(chǎn)生乳汁哺育仔兔，三要供給胎兒生長的需要，而通常在一般飼養(yǎng)條件下，母兔吸收的營養(yǎng)物質(zhì)滿足不了這三個(gè)方面的需求，導(dǎo)致母兔體質(zhì)消耗過大，身體衰竭，乳汁分泌不足；哺乳仔兔由于營養(yǎng)缺乏而體質(zhì)弱、生長緩慢、死亡率高；所懷的胎兒生長發(fā)育緩慢，出生后體弱，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.
