長(zhǎng)毛兔的繁殖和種兔的年齡和營(yíng)養(yǎng)有關(guān)!

影響長(zhǎng)毛兔繁殖力的因素很多,但歸納起來(lái)的主要因素是種兔年齡、種兔營(yíng)養(yǎng)等方面。所以我們?cè)陂L(zhǎng)毛兔種兔的日常管理工作中,要采取針對(duì)性的有效應(yīng)對(duì)措施,來(lái)趨利避害,減少不利因素影響。
There are many factors affecting the fecundity of long-haired rabbits, but the main factors are the age of breeding rabbits, nutrition of breeding rabbits and so on. Therefore, in the daily management of rabbit breeders, we should take effective measures to avoid disadvantages and reduce the impact of adverse factors.
(一)繁殖種兔的年齡
(1) Age of breeding rabbits
長(zhǎng)毛兔種兔繁殖的年齡影響因素,應(yīng)分為兩方面講,一是種兔年齡影響因素,二是種兔年齡的選配影響因素。
There are two factors influencing the reproductive age of rabbits: one is the age of rabbits, the other is the age of rabbits.
1.種兔年齡因素
1. Age Factor of Rabbits
選配長(zhǎng)毛兔的更佳繁殖年齡為1~3歲。1歲之前,公、母兔雖已達(dá)到繁殖年齡,但尚未完全達(dá)到
The optimum reproductive age for long-haired rabbits is 1-3 years old. Before the age of 1, the male and female rabbits have reached the reproductive age, but they have not yet reached it completely.
成熟期,所以育種后出現(xiàn)受胎率低、產(chǎn)仔數(shù)少的現(xiàn)象。3歲之后,公、母兔已進(jìn)入老年期,體質(zhì)漸衰,育種后受胎率亦低,產(chǎn)仔數(shù)少,仔兔品質(zhì)下降,仔兔死亡率高。
At maturity stage, the phenomenon of low conception rate and fewer litters appeared after breeding. After 3 years of age, male and female rabbits have entered the old age, their physique is declining, the fertility rate is low after breeding, the number of litters is small, the quality of young rabbits is declining, and the mortality rate of young rabbits is high.
2.年齡選配因素
2. Age Matching Factors
要根據(jù)與配公、母兔年齡進(jìn)行合理選配。因?yàn)槟挲g與長(zhǎng)毛兔的遺傳穩(wěn)定性有關(guān),同一個(gè)體隨著年齡的不同,所產(chǎn)后代品質(zhì)也往往不同。如果年齡選配不合理,就會(huì)影響繁殖力,其所生產(chǎn)的后代品質(zhì)也難保證。因此,長(zhǎng)毛兔育種繁殖,應(yīng)以年齡的不同而進(jìn)行科學(xué)選配。以確保公、母兔育種所產(chǎn)后代,在生活力和生產(chǎn)性能等方面均有較高的水平。
Reasonable mating should be carried out according to the age of mating male and female rabbits. Because age is related to the genetic stability of long-haired rabbits, the quality of offspring produced by the same individual varies with age. If the age selection is unreasonable, it will affect the fecundity and the quality of the offspring it produces will be difficult to guarantee. Therefore, breeding and reproduction of long-haired rabbits should be scientifically selected according to different ages. To ensure that the offspring produced by male and female rabbit breeding have a high level of vitality and production performance.

(二)繁殖種兔的營(yíng)養(yǎng)
(2) Nutrition of breeding rabbits
長(zhǎng)毛兔與其他許多動(dòng)物一樣,繁殖群體需要合理的飼養(yǎng)管理,其日糧營(yíng)養(yǎng)水平及體況是否合理和適中,對(duì)繁殖力影響非常大,在繁殖前一段時(shí)間內(nèi),要求日糧搭配合理,營(yíng)養(yǎng),繁殖群體體況良好,體質(zhì)康健。
Like many other animals, long-haired rabbits need reasonable feeding and management. Whether their dietary nutrition level and body condition are reasonable and moderate has a great impact on fecundity. During a period of time before reproduction, it is required that the diet should be reasonable, nutritionally comprehensive, and the reproductive population is in good health.
如果繁殖群體的日糧營(yíng)養(yǎng)水平過(guò)高,則易引起公、母兔過(guò)肥,造成脂肪沉積,影響母兔卵泡的發(fā)育和排卵,以及育種的受胎率。當(dāng)然,如果繁殖群體的日糧營(yíng)養(yǎng)水平過(guò)低或日糧營(yíng)養(yǎng)不合理,導(dǎo)致繁殖群體體況不良,體質(zhì)瘦弱,則對(duì)公、母兔的繁殖性能也會(huì)帶來(lái)顯著影響,受胎率下降,產(chǎn)仔數(shù)減少。
If the dietary nutrition level of the reproductive population is too high, it will easily cause overweight of male and female rabbits, resulting in fat deposition, affecting the development of follicles and ovulation of female rabbits, and the fertility rate of breeding. Of course, if the low dietary nutrition level or unreasonable dietary nutrition of the breeding population results in poor health and weak physique of the breeding population, the reproductive performance of the male and female rabbits will also be significantly affected, the conception rate will decrease, and the number of litters will decrease.
