在特種養殖領域，長毛兔（tù）因其的兔毛產量備受關注（zhù）。兔毛作（zuò）為天然蛋白質纖維，其生長具有明顯的階段性（xìng）特征，從幼兔到老年階段，剪毛（máo）周期（qī）需要根據生理特性進行動態調整。本文將深度解析長毛兔全生命周期的剪毛管理策略，為養殖戶提供科學養護指南。

　　In the field of special breeding, long haired rabbits are highly regarded for their high-quality rabbit hair production. As a natural protein fiber, rabbit hair has obvious stage characteristics in its growth. From young rabbits to old age, the shearing cycle needs to be dynamically adjusted according to physiological characteristics. This article will provide a comprehensive analysis of the shearing management strategies for the entire life cycle of long haired rabbits, and offer scientific maintenance guidelines for farmers.

　　一、幼兔期（qī）：生長奠基階段

　　1、 Young Rabbit Stage: Growth Foundation Stage

　　新（xīn）生幼兔在8周齡時迎（yíng）來剪毛時機。此時胎毛已充分生長，粗毛長度可達7.5厘米，細毛達4.5厘米。這個階段的剪毛（máo）操作需（xū）要（yào）格外謹慎，建議采用"部分剪取"策略，僅剔除肩胛部（bù）與背部的過（guò）長毛發，保留腹部及四肢（zhī）的胎毛以維持體（tǐ）溫調力。

　　Newborn rabbits have their first shearing opportunity at 8 weeks of age. At this point, the fetal hair has fully grown, with a coarse hair length of up to 7.5 centimeters and a fine hair length of 4.5 centimeters. The shearing operation at this stage requires extra caution, and it is recommended to adopt a "partial shearing" strategy, only removing excessive hair on the shoulder blades and back, while retaining fetal hair on the abdomen and limbs to maintain temperature regulation ability.

　　在幼兔3月齡前，建議每（měi）90天進行一次輕度修剪。這個階段的毛發生長速度可達每日0.06-0.07毫米，但皮膚屏障功能尚未完善，過度修剪可能導致（zhì）皮膚損傷。某養殖場實踐數據顯示，采用"三留七剪"原則（保留30%基礎毛量）的幼兔，皮膚感染率較完全修剪組降低65%。

　　Before 3 months of age, it is recommended to perform a mild pruning every 90 days for young rabbits. The hair growth rate at this stage can reach 0.06-0.07 millimeters per day, but the skin barrier function is not yet fully developed, and excessive pruning may lead to skin damage. Practical data from a certain breeding farm shows that the skin infection rate of young rabbits using the "three leaves and seven cuts" principle (retaining 30% of the basic hair volume) is 65% lower than that of the completely trimmed group.

　　二、青年期：產能爬坡階（jiē）段

　　2、 Youth period: stage of capacity ramp up

　　當長毛（máo）兔進入4-12月齡的（de）青年期，其新（xīn）陳代（dài）謝達到峰值，毛發生長進入黃金期。這（zhè）個階（jiē）段可實施"階梯式剪毛法"：前兩（liǎng）次剪毛間隔75天，建立標準毛型；從第三次剪毛開始，將周期縮短70天（tiān），以適應加速的毛發生（shēng）長節奏。

　　When the long haired rabbit enters its youth period of 4-12 months old, its metabolism reaches its peak and hair growth enters its golden period. At this stage, the "step by step shearing method" can be implemented: the first two shearing operations are separated by 75 days, with a focus on establishing standard hair patterns; Starting from the third shearing, shorten the cycle to 70 days to adapt to the accelerated pace of hair growth.

　　青年期長毛兔的毛纖維日生長量可達0.08毫米，建議采用"分層采毛"技術（shù）：先剔除3厘米以上的長毛，保留（liú）1.5-2厘米的基礎毛層。這（zhè）種采毛（máo）方（fāng）式既能保證兔毛產量，又能維持皮膚（fū）健康。某研究所對比（bǐ）實驗表（biǎo）明，分層采毛法較（jiào）傳統（tǒng）剪毛（máo）法增產18%，且皮膚損傷率（lǜ）下降40%。

　　The daily growth of hair fibers in young long haired rabbits can reach 0.08 millimeters. It is recommended to use the "layered hair harvesting" technique: first remove hair that is more than 3 centimeters long, and retain the basic hair layer of 1.5-2 centimeters. This hair harvesting method can ensure both rabbit hair production and maintain skin health. A comparative experiment conducted by a certain research institute showed that the layered hair harvesting method increased yield by 18% compared to the traditional shearing method, and the skin damage rate decreased by 40%.

　　三、成年（nián）期：產能穩定階段

　　3、 Adult stage: Stable production capacity stage

　　1-3歲成年期是長毛（máo）兔的產能黃金期，建議實施"季節性（xìng）動態管理"：春秋季節保持75天標準周期，夏季高溫期縮短（duǎn）60天，冬季（jì）延長90天（tiān）。這種（zhǒng）周期調整能有效應對環境溫度對毛發生長的影響，某規模化兔場數據顯（xiǎn）示（shì），季節適應性剪毛（máo）可使全年（nián）產毛量提升22%。

　　The adult period of 1-3 years old is the golden production period for long haired rabbits. It is recommended to implement "seasonal dynamic management": maintain a standard cycle of 75 days in spring and autumn, shorten the high temperature period in summer to 60 days, and extend it to 90 days in winter. This cycle adjustment can effectively cope with the impact of environmental temperature on hair growth. Data from a large-scale rabbit farm shows that seasonal adaptive shearing can increase annual hair production by 22%.

　　成年期長毛兔的毛被具有三層結構：絨毛層、槍毛層、護毛層。建議（yì）采用"三刀（dāo）法"剪毛技術：刀剔除護毛層，第二刀修整槍毛層，第三刀采收（shōu）絨毛層。這種精細化（huà）采（cǎi）毛方式既能保證毛質等級，又能延長毛被再生周期（qī）。

　　The fur coat of adult long haired rabbits has a three-layer structure: villous layer, gun hair layer, and protective hair layer. Suggest using the "three knife method" shearing technique: the first knife removes the protective layer, the second knife trims the gun hair layer, and the third knife collects the fluff layer. This refined hair harvesting method can ensure the quality grade of the hair and extend the regeneration cycle of the hair.

　　四、老年期：養護調整階段

　　4、 Elderly period: maintenance adjustment stage

　　3歲以上的老年兔，其毛囊活（huó）性開始衰退，毛發生長周期延（yán）長。這個階段建議（yì）采取"保育式剪毛"策略：將剪毛周期延長100-120天，剔除過度生（shēng）長的毛尖（保留2厘米基礎毛被），同時增加（jiā）"局部修整"頻（pín）次（每30天處理毛結）。

　　Older rabbits over the age of 3 experience a decline in hair follicle activity and a prolonged hair growth cycle. At this stage, it is recommended to adopt a "conservation style shearing" strategy: extending the shearing cycle to 100-120 days, focusing on removing excessive hair tips (retaining a 2cm base coat), and increasing the frequency of "local trimming" (treating hair knots every 30 days).

　　老年兔皮膚彈性下降，剪毛時應采用"斜角推剪法"，使剪刀與（yǔ）皮膚保持15°夾角（jiǎo），避免垂直剪切造成（chéng）的皮膚損傷。某動物醫院統計顯（xiǎn）示，采用該方法可使老年兔皮膚撕裂傷發（fā）生率從12%降2.3%。

　　The elasticity of the skin of elderly rabbits decreases. When shearing, the "oblique angle pushing cutting method" should be used to maintain a 15 ° angle between the scissors and the skin to avoid skin damage caused by vertical cutting. According to statistics from a certain animal hospital, using this method can reduce the incidence of skin lacerations in elderly rabbits from 12% to 2.3%.

　　五、特殊時期管理要點

　　5、 Key points of management during special periods

　　在產仔（zǎi）期前30天應停止（zhǐ）剪毛，為母兔保留完（wán）整的腹部毛被以構建（jiàn）產仔巢穴。哺乳期結（jié）束後，建議實施"營養（yǎng）強（qiáng）化（huà）剪毛方案"：剪毛後立即補充含胱氨酸、蛋氨（ān）酸的專用飼料，促進毛囊再生。

　　Trimming should be stopped 30 days before the litter giving period to preserve the intact abdominal fur of the female rabbit for constructing a litter nest. After the end of lactation, it is recommended to implement a "nutrition enhanced shearing program": immediately supplement with specialized feed containing cysteine and methionine after shearing to promote hair follicle regeneration.

　　夏季高溫季節，可采用"午間避光剪毛（máo）法（fǎ）"，選擇清晨或傍晚時段操作，避免陽光直射造成的體（tǐ）溫驟（zhòu）升。冬季剪毛後應立即（jí）增加墊料厚度（dù），並在籠內懸掛紅外線保溫燈，維持環（huán）境溫度在15℃以上（shàng）。

　　During the high temperature season in summer, the "midday light avoidance shearing method" can be used, choosing to operate in the early morning or evening to avoid sudden temperature rise caused by direct sunlight. After shearing in winter, the thickness of the padding should be increased immediately, and infrared insulation lamps should be hung in the cage to maintain the ambient temperature above 15 ℃.

　　六、品質管控（kòng）技（jì）術延伸

　　6、 Extension of Quality Control Technology

　　建立"毛被質量動態監測體係"，使（shǐ）用毛發長度測量儀每周檢測背毛、腹毛、四肢毛的生長差異。當不同部位（wèi）毛長差異超過1.5厘米時，啟動"分區采（cǎi）毛"程序，優先修剪（jiǎn）生（shēng）長過速區域的毛發。

　　Establish a "dynamic monitoring system for hair quality" and use a hair length measuring instrument to detect the growth differences of back hair, abdominal hair, and limb hair on a weekly basis. When the difference in hair length between different parts exceeds 1.5 centimeters, initiate the "zone hair harvesting" program and prioritize trimming hair in areas with excessive growth.

　　引入"毛（máo）質電子鼻"檢測技術（shù），通過氣味（wèi）分子分析評估毛被清（qīng）潔度。某智能養殖係統應用顯示，該技術可提前24小時預警毛被汙染風險（xiǎn），使毛產（chǎn）出率提升30%。

　　Introduce the "hair electronic nose" detection technology to evalsuate the cleanliness of hair through odor molecular analysis. A certain intelligent breeding system application shows that this technology can provide 24-hour advance warning of the risk of wool contamination, increasing the yield of high-quality wool by 30%.
