        蒙陰長毛兔的繁殖速度是十分快的,但是想要有一個好的繁殖效果,我們可以注意一下下面的事項!
        The reproductive speed of Mongolian Long Hair Rabbit is very fast, but in order to have a good reproductive effect, we can pay attention to the following matters!
        (一)選好種兔
        (1) Choosing a good breed of rabbit
        一個規(guī)模長毛兔養(yǎng)殖場,選好種兔,是提高長毛兔繁殖力的關(guān)鍵技術(shù)。要做好選種工作,要有系統(tǒng)的選種計劃。要求選擇產(chǎn)毛量高,體型大,適應(yīng)性好,繁殖力強,遺傳性穩(wěn)定的公、母兔留作種用。留種仔兔應(yīng)從母兔的3~5胎中選留。
        A large-scale long-haired rabbit farm and selection of breeding rabbits are the key technologies to improve the fecundity of long-haired rabbits. First of all, we should do a good job in seed selection, and have a systematic seed selection plan. It is required to select male and female rabbits with high wool yield, large size, good adaptability, strong fecundity and stable heredity for breeding. Retained young rabbits should be selected from 3 to 5 fetuses of good female rabbits.
        母兔要求繁殖力強,母性好,而受胎率低,產(chǎn)仔數(shù)少,母性差,泌乳性能不好的母兔,一律不能用于育種繁殖。繁殖用的公母兔應(yīng)有總體培育計劃,有序安排后備繁殖群體。對年齡過大,繁殖能力明顯下降的繁殖種兔予以及時淘汰更替。
        Female rabbits require strong fecundity, good maternity, and low conception rate, fewer litters, poor maternity, poor lactation performance of female rabbits, all can not be used for breeding and reproduction. The male and female rabbits for reproduction should have a general breeding plan and arrange the reserve breeding population in an orderly manner. The breeding rabbits that are too old and whose reproductive capacity is obviously declining should be eliminated and replaced in time.
        (二)科學(xué)管理
        (2) Scientific management
        科學(xué)飼養(yǎng)長毛兔種兔,包括科學(xué)的日糧供給,科學(xué)的疾病防控,科學(xué)的日常管理,合理地控制溫度、濕度、光照、通風(fēng)換氣等等,內(nèi)容廣泛。
        Raising rabbits scientifically includes scientific ration supply, scientific disease prevention and control, scientific daily management, reasonable control of temperature, humidity, light, ventilation and ventilation, etc.
        一是根據(jù)繁殖種群體況,有針對性地提供科學(xué)的日糧。繁殖用的種兔需要合適的體況,保持種兔良好的種用體況,是提高長毛兔繁殖力的重要措施之一。承擔(dān)繁殖任務(wù)的公、母兔,必須有針對性地供給全價營養(yǎng)的日糧,特別是蛋白質(zhì)、維生素和礦物質(zhì)等物質(zhì)的含量要符合種兔繁殖的需要。
        One is to provide scientific diets according to the breeding population. It is one of the important measures to improve the fecundity of long-haired rabbits that breeding rabbits need proper body condition and keep good body condition. The male and female rabbits, who undertake reproductive tasks, must provide a targeted diet with full nutrition, especially the contents of protein, vitamins and minerals, to meet the reproductive needs of breeding rabbits.
        蒙陰長毛兔
        對于過肥的種兔,在日糧中要適調(diào)低高能飼料的含量;對于偏瘦母兔,可采用短期優(yōu)飼的辦法,在配種季節(jié)來臨之前20~30天調(diào)整日糧,增加蛋白質(zhì)、維生素和礦物質(zhì)飼料的供給,以恢復(fù)種兔體況。
        For overfed rabbits, the content of high energy feed should be moderately reduced in the diet; for lean female rabbits, short-term optimal feeding method can be used to adjust the diet 20-30 days before the breeding season, increase the supply of protein, vitamins and mineral feed, in order to restore the body condition of the rabbits.
        二是根據(jù)自然氣候情況,合理控制好繁殖種群的環(huán)境溫度不舌內(nèi)通風(fēng)。長毛兔繁殖,環(huán)境溫度影響較大,如果長毛兔場選址不盡理想,在較差的自然環(huán)境中,一年中總有一些季節(jié)要靠人為來控制環(huán)境的溫度,在育種季節(jié)來臨之前一段時期內(nèi),就要控制好環(huán)境溫度,使繁殖種群恢復(fù)食欲和體質(zhì)。
        Secondly, according to the natural climate, the environmental temperature of the breeding population should be controlled reasonably without ventilation in the tongue. If the site selection of the rabbit farm is not ideal, there will always be some seasons in a year to control the temperature of the environment artificially. In a period of time before the breeding season comes, it is necessary to control the temperature of the environment so as to restore the appetite and physique of the breeding population.
