    講解農家養兔的一些誤區

    發布日期:2016-03-22 來源:http://www.fshxt.net 發布人:admin

      今天我們蒙陰長毛兔廠家小編給大家介紹的是農家養兔有哪些誤區:

      Today we Mengyin Angora rabbit manufacturers Xiaobian to introduce the misunderstanding what rabbit farm:

      一、雜交種兔再留種。兩個家兔品種雜交,雜交一代個大、體壯、抗病力增強、生長速度快,但不宜再留作種用。因為雜交兔遺傳性能很不穩定,后代會出現嚴重的性狀分離,生長緩慢,抗病力減弱,飼料報酬降低。

      A kind of hybrid seed, then. Two rabbit breeds of Hybrid F1, a big, strong disease resistance, enhancement, fast growth, but not for a. Because the rabbit hybrid genetic performance is not stable, offspring will appear serious character separation, slow growth, disease resistance weakened, reducing feed.

      二、盲目引種。對家兔品種缺乏詳細的了解,盲目引種,使所引種兔品質差,不純或者帶病。這是許多養兔戶蒙受損失的主要原因。

      Two, blind introduction. The lack of detailed understanding of rabbit breeds blindly introduced, the introduction of rabbit quality is poor, sick or impure. This is the main reason for many rabbit households suffered losses.

      三、連續血配。很多的養兔戶,為了能讓家兔多產子兔,連續血配,也不考慮母兔的體況及季節的影響,致使產兔不少,活兔不多。血配一窩更好休息半月或一月后再配,同時保證營養平衡。

      Three, continuous blood distribution. A lot of rabbit households, in order to make rabbit prolific rabbit, continuous distribution of blood, not taking into account the mother rabbit's body condition and seasonal effects, cause produce rabbit many, rabbit. Blood with a nest of the best rest and a half months after the match, while ensuring the nutritional balance.

      四、濫用添加劑。有的農戶養兔,不是根據兔群有針對性地使用添加劑,而是認為添加劑越多對兔越好。這不僅增加了飼料成本,造成浪費,而且由于不同的添加劑之間的拮抗作用,不但達不到預期效果,甚還會發生中毒,造成損失。

      Four, the abuse of additives. Some farmers keep rabbits, not according to the rabbit group targeted use of additives, but the more the more the better for the rabbit. This not only increases the cost of feed, resulting in waste, but also due to the antagonism between different additives, not only can not reach the expected results, and even poisoning, resulting in loss of.

      五、喂單一飼料。有些養兔戶,為了省事,怕麻煩,總是喂一種料。養兔戶應根據兔的品種、日齡、用途等,配制合理的全價料,以提高飼料的利用率,增加養兔收益。

      Five, feed a single feed. Some rabbit family, in order to save trouble, always feed a material. Rabbit rabbit family should be based on the variety, age, etc., with the full price of feed and reasonable, in order to improve the utilization rate of feed, increase the income of the rabbit.

      六、料為主草為輔。家兔是草食性動物,不宜過多投喂精料。可有些養兔戶,為了能讓兔快長,過多增加精料的投喂量。這樣不僅增加飼料費用,而且加重了家兔的腸道負擔,影響了其正常的營養代謝,造成腸道病的多發。

      Six, feed mainly supplemented by grass. The rabbit is a herbivorous animal, not too much for feed. Some rabbit family, in order to make rabbit fast long, the excessive increase of feeding amount of fine material. This will not only increase the feed costs, but also increase the burden of the intestinal tract in rabbits, affect the normal metabolism, intestinal disease caused by multiple.

      七、防疫、、投藥同步進行。不少養兔戶,習慣在接種后,馬上,認為這樣可徹底病源,或為了防應激投喂大量的藥物,結果影響了疫苗的免疫效力,導致免疫力下降或防疫失敗。

      Seven, epidemic prevention, disinfection, dosing synchronization. Many households raise rabbit, habits after inoculation, disinfected immediately that it can completely eliminate pathogeny, or in order to prevent stress feeding a large number of drugs, the result of the impact of vaccine immune effect and lead to decreased immunity and vaccination failure.
