        農(nóng)村養(yǎng)殖長毛兔的誤區(qū)你知道嗎

        農(nóng)村養(yǎng)殖長毛兔的誤區(qū)你知道嗎
        Do you know the misunderstanding of raising hairy rabbits in the countryside
        1.自覺引種。對(duì)家兔種類缺乏詳細(xì)的理解,自覺引種,使所引種兔質(zhì)量差,不純或許帶病。這是許多養(yǎng)兔戶遭受損失的次要緣由。
        1. Introducing seeds consciously. Lack of detailed understanding of rabbit species, conscious introduction, so that the quality of introduced rabbits is poor, impure or disease. This is secondary to the loss suffered by many rabbit farmers.
        2.雜交種兔再留種。兩個(gè)家兔種類雜交,雜交一代個(gè)大、體壯、抗病力加強(qiáng)、生長速度快,但不宜再留作種用。由于雜交兔遺傳功能很不波動(dòng),后代會(huì)呈現(xiàn)嚴(yán)重的性狀別離,生長遲緩,抗病力削弱,飼料報(bào)酬降低。
        2. Hybrid rabbits are reserved. The hybridization of two species of rabbits shows that the hybridization generation is large, strong, disease-resistant and fast-growing, but it is not suitable for seed use. Because the genetic function of hybrid rabbits is very unstable, the offspring will show serious character separation, slow growth, weakened disease resistance and reduced feed reward.
        3.延續(xù)血配。很多的養(yǎng)兔戶,爲(wèi)了能讓家兔多產(chǎn)子兔,延續(xù)血配,也不思索母兔的體況及時(shí)節(jié)的影響,致使產(chǎn)兔不少,活兔不多。血配一窩更好休息半月或一月后再配,同時(shí)保證養(yǎng)分均衡。
        3. Continue blood matching. Many rabbit farmers, in order to enable rabbits to produce more rabbits, continue blood matching, do not think about the impact of the physical condition and season of the female rabbits, resulting in a lot of rabbits, live rabbits are not many. A nest of blood matching is best rested for half a month or one month before matching, while ensuring nutrient balance.
        4.料爲(wèi)主草爲(wèi)輔。家兔是草食性植物,不宜過多投喂精料。可有些養(yǎng)兔戶,爲(wèi)了能讓兔快長,過多添加精料的投喂量。這樣不只添加飼料費(fèi)用,而且減輕了家兔的腸道擔(dān)負(fù),影響了其正常的養(yǎng)分代謝,形成腸道病的多發(fā)。
        4. Material is mainly grass supplemented. Rabbits are herbivorous plants and should not be overfed with concentrate. But some rabbit farmers, in order to make the rabbit grow fast, overfeeding concentrate. This not only adds feed costs, but also reduces the burden of intestinal tract of rabbits, affecting their normal nutrient metabolism, resulting in multiple intestinal diseases.

        5.喂單一飼料。有些養(yǎng)兔戶,爲(wèi)了省事,怕費(fèi)事,總是喂一種料。養(yǎng)兔戶應(yīng)依據(jù)兔的種類、日齡、用處等,配制合理的全價(jià)料,以進(jìn)步飼料的應(yīng)用率,添加養(yǎng)兔收益。
        5. Feed a single feed. Some rabbit farmers, in order to save trouble, afraid of trouble, always feed a kind of food. Rabbit farmers should prepare reasonable full-price feed according to the type, age and use of rabbits, in order to improve the application rate of feed and add rabbit income.
        6.濫用添加劑。有的農(nóng)戶養(yǎng)兔,不是依據(jù)兔群有針對(duì)性地運(yùn)用添加劑,而是以為添加劑越多對(duì)兔越好。這不只添加了飼料本錢,形成糜費(fèi),而且由于不同的添加劑之間的拮抗作用,不但達(dá)不到預(yù)期效果,甚還會(huì)發(fā)作中毒,形成損失。
        6. Abuse of additives. Some farmers raise rabbits, not according to the specific use of additives, but think that the more additives, the better for rabbits. This not only adds the cost of feed, but also causes wastage. Because of the antagonistic effect of different additives, not only can the expected effect not be achieved, but also poisoning and loss will occur.
        7.防疫、、投藥同步停止。不少養(yǎng)兔戶,習(xí)氣在接種后,馬上,以為這樣可徹底消弭病源,或爲(wèi)了防應(yīng)激投喂少量的藥物,后果影響了疫苗的免疫效能,招致免疫力下降或防疫失敗。
        7. Epidemic prevention, disinfection and medication should be stopped at the same time. Many rabbit-raising households are accustomed to disinfecting immediately after vaccination, thinking that this can completely eliminate the source of disease, or to prevent stress by feeding a small amount of drugs, the consequences of which affect the immune efficacy of the vaccine, resulting in decreased immunity or epidemic prevention failure.
