      養兔需要注意好的五點控制

      發布日期:2016-09-02 來源:http://www.xtjjsh.com 發布人:admin

      一、溫度控制

      Temperature control

      由于兔汗腺缺乏,所以難以通過出汗來調節體溫,再加上被毛密厚,因而怕熱而有較強的耐寒能力。但溫度過高或過低都會影響兔的生長發育、生產性能和飼養報酬。兔更適宜的溫度一般為:初生仔兔30-32℃,1-4周齡兔20-30℃,生長兔15-25℃,成年兔15-20℃。因此冬季溫度過低對仔兔的生長不利,造成死亡,夏季溫度過高對整個兔群生長造成影響,當溫度超過35℃時則出現中暑現象。所以在建造兔舍時應根據當地的氣候特點,選擇開放、半開放或封閉的兔舍,南方地區一般開放或半開放式,東北應選擇半開放或封閉式兔舍,冬季注意兔舍的保溫防寒,夏季做好防暑降溫,四周種植樹木,降低飼養密度等降溫措施,保證獺兔正常生長、

      Due to lack of sweat glands in rabbits, so it is difficult to regulate body temperature by sweating, plus the hair Mihou, so afraid of the heat and strong cold resistance ability. But the temperature is too high or too low will affect the growth and development of rabbits, production performance and feeding. The most suitable temperature for the rabbit is: newborn rabbit 30-32 degrees, 1-4 weeks old rabbit 20-30 degrees, the growth of rabbit 15-25 degrees, adult rabbit 15-20. Therefore, the winter temperature is too low for the growth of young rabbits, resulting in death, the summer temperature is too high for the entire rabbit population growth, when the temperature exceeds 35 degrees, there is a phenomenon of heat stroke. So the rabbit houses should be built according to the local climate, open, semi open or closed rabbit houses, south open or semi open, the Northeast should choose open or semi closed rabbit houses, winter rabbit houses warm cold, Fangshujiangwen summer, four weeks of planting trees, reduce feeding the density of cooling measures, to ensure the normal growth of rex,

      二、溫度控制

      Two, temperature control

      兔喜歡生活在清潔干燥的環境中,而潮濕的環境易發生各種疾病。因此兔舍的相對濕度應保持在60-65%,一般不能高于70%或低于55%,濕度過大易引起疥癬、球蟲病、濕疹等皮膚病的發生。濕度過大時要加強通風,及時清理糞便降低飼養密度等,降低兔舍濕度,達到正常值。濕度過小易引起呼吸道粘膜干燥,導致細菌、病菌感染發病,當濕度過小時,可在地面噴水增濕,調節到正常水平。

      Rabbits like to live in a clean, dry environment, and the wet environment is prone to a variety of diseases. The relative humidity of rabbit houses should be maintained at 60-65%, generally not higher than 70% or less than 55%, the humidity is too large, easy to cause skin diseases such as eczema, scabies coccidiosis occurrence. The humidity is too large to strengthen the ventilation, in time to clean up the feces to reduce feeding density, etc., to reduce the rabbit house humidity, to reach the normal value. Humidity is too small to cause respiratory mucosa dry, cause bacterial and fungal infection, when the humidity is too small, can be in the ground spray humidification, adjusted to the normal level.

      三、光照控制

      Three, light control

      光照對種公母兔的精液品質,配種能力繁殖性能,發情遲緩起決定性作用。特別是冬季白天短夜間長,如果不增加光照時間,公兔表現為性欲下降,精液品質差,母兔發情不正常。所以,公兔每天應保持光照時間12-14小時,母兔每天應保持光照時間14-16小時。所以在生產過程中應采取人工補充光照的方法,每光照在4-5瓦。育成兔依靠自然光照,一般不需要人工補充光照。實踐證明育成兔采取暗光飼養,可提高增重和毛皮質量。

      Light on the semen quality of male female rabbits, the reproductive performance of breeding capacity, play a decisive role in slow estrus. Especially in winter and short night time, if not increase the light time, male rabbits showed decreased sexual desire, poor semen quality, female rabbits in heat is not normal. Therefore, the male rabbits should be maintained at a time of 12-14 hours per day, the mother rabbit should be maintained at a time of 14-16 hours per day. So in the process of production should be taken artificial supplementary light method, per square meter of light in 4-5 watts. Breeding rabbits rely on natural light, generally do not need artificial light. Practice has proved that bred rabbits take dark rearing, can improve the weight and quality of fur.

      四、有害氣體控制

      Four, harmful gas control

      冬季由于天氣寒冷,關閉門窗,造成空氣不流通,加之糞便及墊草不及時清理,通過發酵可產生大量的氨氣、硫化氫、二氧化碳等有害氣體,當有害氣體增大時可使人有種刺眼的感覺,這時可引起兔呼吸道和眼睛疾病的發生??墒雇昧鳒I、鼻塞、呼吸加快、打噴嚏、結膜發炎,有時造成巴氏桿菌病的發生。調節和控制兔舍內有害氣體的有效措施是:加強通風,保持舍內空氣新鮮,減少飼養密度,及時糞便,減少空氣污染。

      In winter because of the cold weather, close the doors and windows, caused by the air circulation, and manure and straw can not be cleaned in time, by fermentation can produce large amounts of ammonia, hydrogen sulfide, carbon dioxide and other harmful gases, when the harmful gas increases can give people a feeling of dazzling, this can cause respiratory and eye disease of rabbit. Can make the rabbit tears, nasal congestion, breathing speed up, sneezing, conjunctival inflammation, and sometimes cause the occurrence of pap. The effective measures to regulate and control the harmful gas in rabbit's house are: to strengthen the ventilation, keep the fresh air in the house, reduce the feeding density, remove the feces in time, and reduce the air pollution.

      五、噪音控制

      Five, noise control

      兔膽小怕驚,對外界的環境十分敏感,一有異常噪音及豎耳靜聽或驚恐萬分,出現精神癥狀,亂蹦亂撞,易引起母兔流產,拒絕喂奶,正在分娩的母兔會咬死或吃掉仔兔。因此,在造兔場時要遠離公路、和噪音大的地方,家庭飼養時要注意安靜,減少突出噪音的發生,飼喂時要防治大聲喧嘩,禁止在兔舍周圍燃放鞭炮,不能讓貓、等動物進入兔舍。

      Rabbit timid fear scared, the outside environment is very sensitive to an abnormal noise and ear listening or panic, psychiatric symptoms, bounce rattling, easy to cause abortion of female rabbits, refused to breast-feeding, giving birth mother rabbit will kill or eat the rabbit. Therefore, making Warren to stay away from roads, and noise of the place, keeping the family should pay attention to reduce the noise of the quiet, prominent, fed to control noise, is prohibited in the rabbit house around setting off firecrackers can not let the cat and dog animal into the rabbit house.
