兔子养殖户都非常重视种兔的培育，特别是大型养殖场，因为种兔品质才能有效提升兔场的繁殖率，提高兔场的经济效益。而筛选的幼兔作为后备种兔是保持种兔品质及数量的关键措施，那么应该如何选留后备种兔呢？希望下面长毛兔厂家的分享可以给你带来帮助！

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为种兔，因为大部分母兔一胎的配种的时机没有完全成熟，所以母兔一胎产下的仔兔的质量往往比较低，大多存在体型小、生长速度缓慢等问题，所以好不要选母兔一胎产下的仔兔作为种兔，之后母兔产下的兔子，可以根据仔兔各个方面的对比，筛选出较为的仔兔选为后备种兔。

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、在母兔繁殖率较低的情况下，该母兔产下的后代不宜作为种兔。比母兔连续几胎的产仔数低于5只，且母兔发情迟缓，发情不明显等，则说明母兔的繁殖率低下，其生下的仔兔不适合作为后备种兔。后备种兔好选择母兔每胎产仔数在6~7只以上的仔兔中选择。

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、需注意检查后备种兔是否患有遗传性疾病，比如有没有牙齿生长异常、八字腿或关节畸形等问题，如果有，则不适合留作种兔，因为患有这类疾病的兔子往往难以饲养，且对繁殖有一定影响。

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、如果母兔的母性较差，则该母兔的后代不适合留作种兔。通常母兔的母性的好坏和认为因素有关之外，与遗传有着更大的关联。通常母性差的母兔所繁殖的后代的母兔的母性也比较差，容易出现产后不拔毛、泌乳量不足、咬仔等问题。

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、等仔兔年龄大一些之后，再次对后备种兔进行筛查。一般公兔在4月龄时会“掉蛋”，对于没有“掉蛋”，的公兔，应该将其淘汰。对母兔的筛查，则主要检查其乳头的数量，母兔的乳头数量以6~8个为宜，乳头量过多过少的母兔都不适合作为种兔。

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.
