    新西蘭兔養殖的研究喂養技術

    發布日期:2023-09-13 來源:http://www.tunjie.cn 發布人:admin

    我國已引入多年,具有早期生長速度快,產肉力高,肉質肥嫩的特點,毛皮質地也很好,具有較高的經濟價值,而且是的實驗動物,廣泛應用于學、生物學領域的研究,加強對新西蘭兔規范化養殖技術的研究具有十分現實的意義。
    China has introduced it for many years, with the characteristics of fast early growth rate, high meat production capacity, and plump and tender meat quality. The fur and cortex are also very good, which has high economic value. Moreover, it is an experimental animal widely used in the fields of science and biology. Strengthening the research on standardized breeding techniques for New Zealand rabbits has very practical significance.
    合理分群剛斷奶的幼兔在分群時應根據體型大小、體質強弱來決定。對體型小而弱的須小心照料,籠養
    Reasonably grouping young rabbits that have just been weaned should be determined based on their body size and physical strength when grouping. Small and weak individuals should be carefully taken care of and kept in captivity
    的每籠不得超過4只,在整個飼養期內,盡量不要換兔籠和變更兔群。精心飼養斷奶幼兔頭一、二天,往往情緒不安、食欲不振,因此,飼料盡量與斷奶前相似,每天多喂幾次,飼料量逐漸,待適應后飼料品種要多樣化,飼料要新鮮、營養要,而且要容易消化,精粗飼料要合理搭配,日糧中粗纖維含量在15·左右,粗蛋白質要求達到17%,每只每天喂給精飼料40-60克,青飼料300-400克,隨著日齡的要逐步添青粗飼料喂養。提供適宜溫度斷奶初期溫度是否適宜對幼兔成活率有著重要關系,試驗表明:45日齡的幼兔在18-20℃的溫度下,比生活在10℃左右中增重快、死亡率低,因此,幼兔斷奶后兩周內舍溫盡可能

    Each cage should not exceed 4 rabbits, and during the entire breeding period, try not to change the rabbit cage or group. Carefully raising weaned young rabbits for one or two days often leads to emotional unease and loss of appetite. Therefore, the feed should be as similar as before weaning. Feed more times a day, gradually increasing the amount of feed. After adaptation, the feed variety should be diverse, fresh, nutritious, and easy to digest. Concentrated and coarse feed should be reasonably matched, with a crude fiber content of about 15% in the diet and a crude protein requirement of 17%. Each rabbit should be fed 40-60 grams of concentrate feed every day, 300-400 grams of green feed, gradually adding green coarse feed as you age. Providing a suitable temperature for early weaning has an important relationship with the survival rate of young rabbits. Experiments have shown that young rabbits aged 45 days gain weight faster and have a lower mortality rate at temperatures ranging from 18 to 20 ℃ compared to those living at around 10 ℃. Therefore, the temperature should be kept as warm as possible within two weeks after weaning
    控制在15-20℃,室溫過高、過低都會影響幼兔的日增重和成活率。搞好疫病要保持籠舍干燥、清潔、通風,定期要用5%的來蘇兒溶液進行,注重飼料衛生,不喂變質料,青飼料上的污泥要洗凈晾干再喂,并選喂一些 和抗球蟲添加劑,以控制腸炎、拉稀的球蟲病的發生。
    Controlled at 15-20 ℃, high or low room temperature can affect the daily weight gain and survival rate of young rabbits. To prevent epidemics, it is necessary to keep the cage dry, clean, and well ventilated. Regular use of 5% Lysol solution should be carried out, and attention should be paid to feed hygiene. Do not feed substandard materials. The sludge on the green feed should be washed and dried before feeding, and some anti coccidiosis additives should be selected to control the occurrence of enteritis and diarrhea caused by coccidiosis.
    空懷期種母兔配種前的種母兔稱為空懷母兔,這一時期的工作比較簡單。除了搞好日常的衛生、供給日常所需的日糧外,要注意的是,這個時期的種母兔不能過于肥胖或瘦弱,否則不利于配種。建議飼料配方為:玉米22%、豆粕16%、麩皮20%、草粉40%、微量元素2%。每只每天飼喂克,每天飼喂3次。六、公羊兔的配種技術公羊兔種兔經過一段時間的飼養,如果條件成熟就可以進行繁殖了。繁殖是公羊兔數量和的關鍵性措施。
    The mother rabbit before mating during the empty pregnancy period is called the empty pregnancy mother rabbit, and the work during this period is relatively simple. In addition to maintaining good daily hygiene and providing the necessary daily diet, it should be noted that the mother rabbits during this period should not be too fat or thin, otherwise it is not conducive to breeding. The recommended feed formula is: corn 22%, soybean meal 16%, bran 20%, grass powder 40%, and trace element 2%. Each animal is fed grams per day, three times a day. 6、 The breeding technique for male sheep and rabbits. After a period of raising, if the conditions are ripe, the male sheep and rabbit can breed. Reproduction is a key measure for the quantity and quality of male sheep and rabbits.
