          提高蒙陰長毛兔繁殖力的主要措施有哪些

          What are the main measures to improve the reproductive capacity of Mongolian long haired rabbits in the shadebase64_image

          1、科學(xué)喂養(yǎng)

          1. Scientific feeding

          維持種兔的身體狀況是提高蒙陰長毛兔繁殖能力的重要措施之一。繁殖季節(jié)到來前,應(yīng)逐漸增加蛋白質(zhì)飼料、礦物質(zhì)、維生素的量。對(duì)于過于肥胖的種兔,應(yīng)適當(dāng)限制高能量飼料的用量,對(duì)于過于瘦弱的種兔,應(yīng)加強(qiáng)飼喂,以維持繁殖的體況,使種兔性功能旺盛。

          Maintaining the physical condition of breeding rabbits is one of the important measures to improve the reproductive ability of Mongolian long haired rabbits. Before the arrival of the breeding season, the amount of protein feed, minerals, and vitamins should be gradually increased. For excessively obese breeding rabbits, the amount of high-energy feed should be appropriately limited. For excessively thin breeding rabbits, feeding should be strengthened to maintain their reproductive condition and promote their sexual function.

          2、年齡結(jié)構(gòu)合理

          2. Reasonable age structure

          種兔群體中,幼、壯、老種兔應(yīng)有合理的年齡結(jié)構(gòu)。種兔一般使用3年左右,每年約有1/3被淘汰。因此,每年應(yīng)選留1/3以上的儲(chǔ)備兔,進(jìn)一步選育作為種兔來源。整個(gè)種兔種群應(yīng)以青壯年為主。如果老種兔比例過大,就會(huì)影響整個(gè)兔群的生產(chǎn)。

          In the rabbit breeding population, young, strong, and old rabbits should have a reasonable age structure. Rabbit breeding is generally used for about 3 years, and about one-third of them are eliminated each year. Therefore, more than one-third of the reserve rabbits should be selected each year for further breeding as a source of breeding rabbits. The entire rabbit population should be dominated by young adults. If the proportion of old breed rabbits is too high, it will affect the production of the entire rabbit population.

          3.重復(fù)繁殖

          3. Repetitive reproduction

          正常情況下,只要母兔發(fā)情正常,公兔精液質(zhì)量良好,只需交配一次即可懷孕。但為了保證母兔受孕,防止假孕,同一只公兔可在次配種后6-8小時(shí)再次交配。次交配的目的是刺激母兔排卵,第二次交配的目的是正式受孕。據(jù)實(shí)驗(yàn),重復(fù)繁殖的受胎率可達(dá)95%-100%,每窩產(chǎn)仔數(shù)為6-8頭。

          Under normal circumstances, as long as the female rabbit has normal estrus and the male rabbit's semen quality is good, only one mating is needed to conceive. But in order to ensure the pregnancy of the female rabbit and prevent false pregnancy, the same male rabbit can mate again 6-8 hours after the first mating. The purpose of the first mating is to stimulate ovulation in female rabbits, while the purpose of the second mating is to officially conceive. According to experiments, the conception rate of repeated reproduction can reach 95% -100%, with 6-8 offspring per litter.

          4.雙重育種

          4. Dual breeding

          一只母兔與兩只不同血緣關(guān)系的公兔連續(xù)交配,交配間隔時(shí)間不超過20-30分鐘。目的是利用不同公兔的精子相互競(jìng)爭(zhēng),以提高卵子的受精率。同時(shí),由于優(yōu)良精子和卵子結(jié)合數(shù)量的增加,兔子的生命力就會(huì)旺盛,成活率也會(huì)很高。據(jù)實(shí)驗(yàn),采用雙配的受胎率比對(duì)照組提高25%-30%,產(chǎn)仔數(shù)增加10%-20%。但雙配只能用于商品兔生產(chǎn),不能用于種兔生產(chǎn)。

          A female rabbit continuously mates with two male rabbits of different blood relationships, with a mating interval of no more than 20-30 minutes. The purpose is to utilize the excellent sperm of different male rabbits to compete with each other, in order to improve the fertilization rate of eggs. At the same time, due to the increase in the number of excellent sperm and egg combinations, the vitality of rabbits will be vigorous, and the survival rate will also be high. According to the experiment, the conception rate of the double matched group increased by 25% -30% compared to the control group, and the litter size increased by 10% -20%. But the dual configuration can only be used for the production of commercial rabbits and cannot be used for the production of breeding rabbits.
