種兔母兔難產(chǎn)的造成的三項(xiàng)原因?

發(fā)布日期:2016-12-02 來源:http://gdwk56.com 發(fā)布人:admin

1、初產(chǎn)適時(shí)配種。種兔母兔初次配種年齡在5.5個(gè)月齡左右,體重在2.75公斤左右。如果初產(chǎn)年齡、體重過高、過重,初產(chǎn)種兔母兔的難產(chǎn)率有增高的趨勢。

1 primiparous, timely breeding. Rabbit rabbit mother first breeding at the age of 5.5 months old, weighing 2.75 kg. If the age of first, overweight, overweight, primiparous female rabbit rabbit dystocia rate increased.

2、種兔母兔懷孕期提供適宜的營養(yǎng)。有些兔子養(yǎng)殖戶有一個(gè)誤區(qū):認(rèn)為種兔一旦懷孕,飼喂的越多越好,飼料營養(yǎng)越高越好,其實(shí)據(jù)山西省農(nóng)科院畜牧獸醫(yī)研究所兔子養(yǎng)殖研究室在開展“種兔飼養(yǎng)標(biāo)準(zhǔn)及預(yù)混料”課題研究中發(fā)現(xiàn),對于懷孕的種兔母兔,采用飼料營養(yǎng)水平為低能量(10.47兆焦/千克)、中蛋白水平(粗蛋白17.5%),限制飼養(yǎng)(170克/天)的飼養(yǎng)方式,窩產(chǎn)仔數(shù)更高,未發(fā)現(xiàn)有難產(chǎn)情況發(fā)生.

2, rabbit rabbit pregnancy to provide appropriate nutrition. Some rabbit farmers have a misunderstanding that the rabbit once pregnant, feeding more, feed nutrition is good, in fact, according to the rabbit of Shanxi Academy of animal husbandry and Veterinary Research Institute of aquaculture research laboratory in carry out the "rabbit feeding standard and premix" found in the research, for pregnant female rabbit rabbit, the feed nutrition level low energy (10 trillion and 470 billion kJ / kg) and protein levels (17.5% crude protein), restricted feeding (170 g / day) feeding, litter size was not found to have the highest, dystocia occurs.

而采用高能量、高蛋白的營養(yǎng)水平,產(chǎn)仔數(shù)減少,分娩障礙發(fā)生率較高。因?yàn)楦吣芰?、高蛋白造成胎兒過大,占據(jù)子宮空間,引起死胎增加,同時(shí)胎兒過大,難產(chǎn)的風(fēng)險(xiǎn)增大。但如果懷孕種兔母兔體質(zhì)過弱,由于產(chǎn)力不足,也易造成難產(chǎn)。因此在生產(chǎn)中根據(jù)種兔母兔的體況,調(diào)節(jié)飼喂量,保持7~8成膘情就可以了,待分娩后再逐漸增加飼喂量。

The nutrition level of high energy, high protein, decreased litter size, birth disorder incidence. Because of the high energy, high protein cause fetal uterus is too large, occupy the space, causing stillbirth increased, while the fetus is too large, the increased risk of dystocia. But if the pregnant female rabbit rabbit body is too weak, because the production capacity is insufficient, but also easy to cause dystocia. Therefore, in the production of female rabbit rabbit according to the body condition, adjust feeding amount, keep 7 ~ 8 of the can, stay after delivery and then gradually increase the feeding amount.

3、胎位不正。種兔難產(chǎn)也可能是胎位、胎向、胎勢不正引起。

3, malposition. Rabbit dystocia may also be the fetal position, fetal and fetal potential is not caused to.
