長(zhǎng)毛兔因其濃密柔順的被毛成為特種養(yǎng)殖領(lǐng)域的熱門(mén)品種，但在換毛期出現(xiàn)的異常掉毛現(xiàn)象常令養(yǎng)殖戶(hù)困擾。這一生理過(guò)程受光照周期、激素水平及營(yíng)養(yǎng)狀況共同調(diào)控，需通過(guò)系統(tǒng)化管理實(shí)現(xiàn)被毛健康更替。
Long haired rabbits have become a popular breed in the field of special breeding due to their dense and soft fur, but the abnormal shedding of fur during the molting period often troubles breeders. This physiological process is regulated by the light cycle, hormone levels, and nutritional status, and requires systematic management to achieve healthy replacement of fur.
一、換毛期生理機(jī)制解析
1、 Analysis of Physiological Mechanisms during Hair Replacement Period
長(zhǎng)毛兔每年經(jīng)歷季節(jié)性換毛，春秋兩季尤為明顯。褪黑素分泌量隨日照時(shí)長(zhǎng)變化，觸發(fā)毛囊由生長(zhǎng)期向休止期過(guò)渡。某研究所觀測(cè)數(shù)據(jù)顯示，日照時(shí)間減少會(huì)引發(fā)兔體內(nèi)皮質(zhì)醇水平波動(dòng)，加速舊毛脫落。此階段需關(guān)注兔舍光照管理，避免突然改變光照周期導(dǎo)致應(yīng)激性脫毛。
Long haired rabbits undergo seasonal molting every year, particularly in spring and autumn. The secretion of melatonin varies with the duration of sunlight, triggering the transition of hair follicles from the growth phase to the resting phase. Observational data from a certain research institute shows that a decrease in sunlight exposure can cause fluctuations in the levels of cortisol in rabbits, accelerating the shedding of old hair. At this stage, attention should be paid to the lighting management of the rabbit house to avoid sudden changes in the lighting cycle that may cause stress-induced hair loss.
二、營(yíng)養(yǎng)調(diào)控技術(shù)要點(diǎn)
2、 Key points of nutritional regulation technology
氨基酸平衡：被毛蛋白中含硫氨基酸占比達(dá)18%，需在日糧中補(bǔ)充蛋氨酸、胱氨酸。某飼料企業(yè)研發(fā)的長(zhǎng)毛兔專(zhuān)用預(yù)混料，通過(guò)添加酵母水解物使毛纖維直徑提升，斷毛率降低。
Amino acid balance: The proportion of sulfur-containing amino acids in hair protein reaches 18%, and methionine and cysteine need to be supplemented in the diet. The special premix for long haired rabbits developed by a certain feed enterprise increases the diameter of hair fibers and reduces the breakage rate by adding yeast hydrolysate.
微量元素協(xié)同：鋅參與角蛋白合成，銅影響毛色光澤度。某養(yǎng)殖場(chǎng)實(shí)踐表明，日糧銅含量控制在8-10ppm時(shí)，兔毛黃染率下降。
Trace element synergy: Zinc participates in keratin synthesis, while copper affects hair color and glossiness. Practice in a certain breeding farm has shown that when the copper content in the diet is controlled at 8-10 ppm, the yellow staining rate of rabbit hair decreases.
脂肪酸供給：亞油酸缺乏會(huì)導(dǎo)致毛囊萎縮。添加3%冷榨亞麻籽油可使新生毛被柔順度提升，皮膚炎發(fā)生率降低。
Fatty acid supply: Lack of linoleic acid can lead to hair follicle atrophy. Adding 3% cold pressed flaxseed oil can improve the softness of newly formed hair and reduce the incidence of dermatitis.
三、環(huán)境管理關(guān)鍵措施
3、 Key measures for environmental management
溫濕度控制：兔舍溫度維持在15-25℃，濕度控制在55-65%。某規(guī)模化兔場(chǎng)數(shù)據(jù)顯示，高溫高濕環(huán)境會(huì)使換毛期延長(zhǎng)，異常脫毛量增加。
Temperature and humidity control: The temperature in the rabbit house is maintained at 15-25 ℃, and the humidity is controlled at 55-65%. Data from a large-scale rabbit farm shows that high temperature and humidity environments can prolong the molting period and increase abnormal hair removal.
空氣質(zhì)量?jī)?yōu)化：氨氣濃度超過(guò)20ppm會(huì)刺激毛囊。采用生物發(fā)酵床技術(shù)，配合每小時(shí)3次機(jī)械通風(fēng)，可使兔舍空氣質(zhì)量達(dá)標(biāo)。
Air quality optimization: Ammonia concentration exceeding 20ppm can stimulate hair follicles. The use of biological fermentation bed technology, combined with mechanical ventilation three times per hour, can ensure that the air quality in the rabbit house meets the standard.
光照強(qiáng)度調(diào)節(jié)：避免直射強(qiáng)光，采用40W燈提供10-15Lux漫射光，防止紫外線灼傷新生毛囊。
Light intensity adjustment: Avoid direct strong light and use a 40W energy-saving lamp to provide 10-15Lux diffused light, preventing UV rays from burning newly formed hair follicles.
四、日常護(hù)理操作規(guī)范
4、 Daily nursing operation standards
梳毛頻率優(yōu)化：換毛期每日用彈性鋼絲梳梳理2次，每次10分鐘。某養(yǎng)殖基地對(duì)比發(fā)現(xiàn)，規(guī)范梳毛可使浮毛率提升，減少毛球癥發(fā)生。
Optimization of combing frequency: During the hair changing period, use an elastic steel wire comb to comb twice a day for 10 minutes each time. A comparison of a certain breeding base found that standardized combing can improve the removal rate of floating hair and reduce the occurrence of hairball disease.
藥浴時(shí)機(jī)選擇：在換毛高峰期后進(jìn)行藥浴，使用含0.15%氯己定的中藥洗劑，可殺滅體表寄生蟲(chóng)，某病例中螨蟲(chóng)感染率因此下降。
Timing of medicated bathing: After the peak period of hair replacement, medicated bathing is performed using a traditional Chinese medicine detergent containing 0.15% chlorhexidine, which can kill surface parasites and reduce the infection rate of mites in a certain case.
應(yīng)激防控：避免在換毛期進(jìn)行轉(zhuǎn)群、免疫等操作。某實(shí)驗(yàn)顯示，運(yùn)輸應(yīng)激會(huì)使皮質(zhì)醇水平升高，導(dǎo)致毛囊提前進(jìn)入退行期。
Stress prevention and control: Avoid group switching, immunization, and other operations during the shedding period. A certain experiment showed that transportation stress can increase cortisol levels, leading to premature degeneration of hair follicles.
五、異常脫毛鑒別診斷
5、 Differential diagnosis of abnormal hair removal
營(yíng)養(yǎng)性脫毛：背部出現(xiàn)“V”形脫毛區(qū)，毛干脆弱易斷。需檢測(cè)飼料粗蛋白含量，某病例通過(guò)添加賴(lài)氨酸使癥狀緩解。
Nutritional hair removal: A "V" - shaped hair removal area appears on the back, and the hair shaft is fragile and prone to breakage. It is necessary to test the crude protein content of the feed. In a certain case, the symptoms were relieved by adding lysine.
寄生蟲(chóng)性脫毛：腹股溝、耳后出現(xiàn)圓形脫毛斑，皮膚增厚。顯微鏡檢查發(fā)現(xiàn)疥螨時(shí)，需使用伊維菌素注射液。
Parasitic hair removal: circular hair removal spots appear in the groin and behind the ears, and the skin thickens. When scabies mites are detected by microscopic examination, treatment with ivermectin injection is necessary.
真菌性脫毛：脫毛區(qū)呈圓形或不規(guī)則形，邊緣有鱗屑。采用伍德氏燈檢查，確診后使用特比萘芬噴霧劑。
Fungal hair removal: The hair removal area is circular or irregular in shape, with scales on the edges. Wooden lamp examination was used, and terbinafine spray was used after diagnosis.
長(zhǎng)毛兔換毛期管理需構(gòu)建“營(yíng)養(yǎng)-環(huán)境-護(hù)理”三位一體防控體系。通過(guò)精準(zhǔn)調(diào)控日糧營(yíng)養(yǎng)素、優(yōu)化兔舍微環(huán)境、規(guī)范日常護(hù)理操作，可顯著提升被毛品質(zhì)。當(dāng)出現(xiàn)異常脫毛時(shí)，需結(jié)合臨床檢查與實(shí)驗(yàn)室診斷實(shí)施靶向，確保養(yǎng)殖效益與動(dòng)物福利的雙重保障。
The management of the shedding period of long haired rabbits requires the establishment of a three in one prevention and control system of "nutrition environment care". By precisely regulating the nutrients in the diet, optimizing the microenvironment of the rabbit house, and standardizing daily nursing operations, the quality of the fur can be significantly improved. When abnormal hair removal occurs, targeted therapy should be implemented in combination with clinical examination and laboratory diagnosis to ensure the dual protection of breeding benefits and animal welfare.
