兔子養(yǎng)殖戶都非常重視種兔的培育，特別是大型養(yǎng)殖場，因為種兔品質(zhì)才能有效提升兔場的繁殖率，提高兔場的經(jīng)濟效益。而篩選的幼兔作為后備種兔是保持種兔品質(zhì)及數(shù)量的關(guān)鍵措施，那么應(yīng)該如何選留后備種兔呢？希望下面
長毛兔廠家的分享可以給你帶來幫助！
Rabbit breeders attach great importance to the breeding of breeding rabbits, especially large breeding farms, because the breeding rate of rabbit farms can be effectively improved and the economic benefits of rabbit farms can be improved only by the excellent quality of breeding rabbits. The selection of excellent young rabbits as reserve breeding rabbits is the key measure to maintain the quality and quantity of breeding rabbits, so how to select and retain reserve breeding rabbits? I hope the following share from the rabbit manufacturers can help you!
1、母兔胎生下的仔兔不宜作為種兔，因為大部分母兔一胎的配種的時機沒有完全成熟，所以母兔一胎產(chǎn)下的仔兔的質(zhì)量往往比較低，大多存在體型小、生長速度緩慢等問題，所以好不要選母兔一胎產(chǎn)下的仔兔作為種兔，之后母兔產(chǎn)下的兔子，可以根據(jù)仔兔各個方面的對比，篩選出較為的仔兔選為后備種兔。
1. The baby rabbits born at the first birth of the mother rabbit should not be used as the breeding rabbits, because the timing of breeding of most of the mother rabbits is not fully mature, so the quality of the baby rabbits born at the first birth of the mother rabbit is often low, most of them have problems such as small size and slow growth, so it is better to choose the baby rabbits born at the first birth of the mother rabbit as the breeding rabbits, and then the rabbits born by the mother rabbit can be compared according to various aspects of the baby rabbits, The better baby rabbits were selected as the reserve breeding rabbits.
2、在母兔繁殖率較低的情況下，該母兔產(chǎn)下的后代不宜作為種兔。比母兔連續(xù)幾胎的產(chǎn)仔數(shù)低于5只，且母兔發(fā)情遲緩，發(fā)情不明顯等，則說明母兔的繁殖率低下，其生下的仔兔不適合作為后備種兔。后備種兔好選擇母兔每胎產(chǎn)仔數(shù)在6~7只以上的仔兔中選擇。
2. Under the condition of low reproduction rate of the female rabbit, the offspring of the female rabbit should not be used as the breeding rabbit. The number of litters produced in several successive pregnancies is less than 5, and the oestrus of the female rabbit is slow and not obvious, which indicates that the reproduction rate of the female rabbit is low, and the offspring of the female rabbit is not suitable for use as a reserve breeding rabbit. Reserve breeding rabbits are good choices for female rabbits.
3、需注意檢查后備種兔是否患有遺傳性疾病，比如有沒有牙齒生長異常、八字腿或關(guān)節(jié)畸形等問題，如果有，則不適合留作種兔，因為患有這類疾病的兔子往往難以飼養(yǎng)，且對繁殖有一定影響。
3. It is necessary to check whether the reserve breeding rabbit has genetic diseases, such as abnormal tooth growth, splayed legs or joint deformity. If so, it is not suitable to keep it as a breeding rabbit, because rabbits with such diseases are often difficult to raise and have some impact on reproduction.
4、如果母兔的母性較差，則該母兔的后代不適合留作種兔。通常母兔的母性的好壞和認為因素有關(guān)之外，與遺傳有著更大的關(guān)聯(lián)。通常母性差的母兔所繁殖的后代的母兔的母性也比較差，容易出現(xiàn)產(chǎn)后不拔毛、泌乳量不足、咬仔等問題。
4. If the mother rabbit has a poor maternal nature, the offspring of the mother rabbit is not suitable for keeping as a breeding rabbit. Generally, the maternal quality of female rabbits is more closely related to genetics than other factors. Generally, the offspring of the mother rabbit bred by the mother rabbit with poor maternal quality are also poor in maternal quality, and are prone to problems such as non-pulling after childbirth, insufficient lactation, and biting.
5、等仔兔年齡大一些之后，再次對后備種兔進行篩查。一般公兔在4月齡時會“掉蛋”，對于沒有“掉蛋”，的公兔，應(yīng)該將其淘汰。對母兔的篩查，則主要檢查其乳頭的數(shù)量，母兔的乳頭數(shù)量以6~8個為宜，乳頭量過多過少的母兔都不適合作為種兔。
5. After the young rabbits are older, the reserve breeding rabbits will be screened again. Generally, male rabbits will "drop eggs" at the age of 4 months. For male rabbits without "drop eggs", they should be eliminated. For the screening of female rabbits, the number of nipples is mainly checked. The number of nipples of female rabbits should be 6~8. Female rabbits with too many or too few nipples are not suitable for breeding rabbits.
The above are some suggestions for the selection of reserve breeding rabbits from the rabbit manufacturers, hoping to help the rabbit farmers correctly select excellent reserve breeding rabbits. More rabbit breeding matters come to our website http://www.lilituan.com Understand!
