      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、科學喂養

      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。繁殖季節到來前,應逐漸增加蛋白質飼料、礦物質、維生素的量。對于過于肥胖的種兔,應適當限制高能量飼料的用量,對于過于瘦弱的種兔,應加強飼喂,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、年齡結構合理

      2. Reasonable age structure

      種兔群體中,幼、壯、老種兔應有合理的年齡結構。種兔一般使用3年左右,每年約有1/3被淘汰。因此,每年應選留1/3以上的儲備兔,進一步選育作為種兔來源。整個種兔種群應以青壯年為主。如果老種兔比例過大,就會影響整個兔群的生產。

      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.重復繁殖

      3. Repetitive reproduction

      正常情況下,只要母兔發情正常,公兔精液質量良好,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。據實驗,重復繁殖的受胎率可達95%-100%,每窩產仔數為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系的公兔連續交配,交配間隔時間不超過20-30分鐘。目的是利用不同公兔的精子相互競爭,以提高卵子的受精率。同時,由于優良精子和卵子結合數量的增加,兔子的生命力就會旺盛,成活率也會很高。據實驗,采用雙配的受胎率比對照組提高25%-30%,產仔數增加10%-20%。但雙配只能用于商品兔生產,不能用于種兔生產。

      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.
