長毛兔憑借其高度特化的消化生理機制構(gòu)建了獨特的營養(yǎng)代謝體系：作為單胃草食動物，其消化道長度可達體長15倍，盲腸微生物群落與球囊組織的協(xié)同作用使粗纖維消化率達65%-70%，日糧中12%-16%的粗纖維含量既能維持腸道正常蠕動節(jié)律（0.8-1.2次/分鐘），又可抑制有害菌群增殖（大腸桿菌數(shù)量降低2個數(shù)量級），而鈣磷比耐受范圍（1.5:12:1）顯著優(yōu)于常規(guī)畜禽的代謝閾值。
Long haired rabbits have constructed a unique nutritional metabolism system based on their highly specialized digestive physiological mechanisms: as a monogastric herbivore, their digestive tract length can reach 15 times body length. The synergistic effect of cecal microbiota and balloon tissue enables a crude fiber digestion rate of 65% -70%. A crude fiber content of 12% -16% in the diet can maintain normal intestinal peristalsis rhythm (0.8-1.2 times/minute) and inhibit the proliferation of harmful bacteria (reducing the number of Escherichia coli by 2 orders of magnitude), while the calcium phosphorus tolerance range (1.5:1 to 2:1) is significantly better than the metabolic threshold of conventional livestock and poultry.
兔毛生長周期遵循雙重調(diào)控機制：幼兔經(jīng)歷兩次年齡性換毛（30-100日齡，二次130-190日齡），成年兔則呈現(xiàn)春秋季節(jié)性換毛特征（春季換毛期21-28天，秋季35-42天），病理性脫毛多由營養(yǎng)代謝失衡引發(fā)（血清總蛋白<50g/L時脫毛率增加3.8倍）。選育優(yōu)良個體需關(guān)注體軀指數(shù)（胸圍/體長≥1.1）、毛囊密度（≥800個/cm2）及四肢骨骼強度（掌骨骨密度≥1.2g/cm3）。
The growth cycle of rabbit hair follows a dual regulatory mechanism: young rabbits undergo two age-related hair changes (first 30-100 days old and second 130-190 days old), while adult rabbits exhibit seasonal hair changes in spring and autumn (21-28 days in spring and 35-42 days in autumn). Pathological hair loss is often caused by nutritional metabolism imbalance (hair loss rate increases by 3.8 times when serum total protein<50g/L). Breeding excellent individuals requires attention to body mass index (chest circumference/body length ≥ 1.1), hair follicle density (≥ 800/cm 2), and limb bone strength (metacarpal bone density ≥ 1.2g/cm 3).
飼養(yǎng)管理中，青粗飼料占比需維持體重的20%-25%（干物質(zhì)基礎(chǔ)），采食序列優(yōu)先選擇多葉型牧草（粗蛋白>18%）與根莖類飼料（淀粉含量<25%），其特有的食糞行為可使軟糞中VB12吸收率提升37%。剪毛周期優(yōu)化需平衡毛品質(zhì)與產(chǎn)量：75天養(yǎng)毛期時特級毛占比達42%（毛長≥6cm），而60天周期雖年產(chǎn)量增加8%，但次級毛比例升55%。剪毛操作需遵循背脊分線法，采用弧形剪刀保持15°切入角度，剪后毛纖維含水率應(yīng)控制在8%-12%，倉儲時需使用雙層防潮紙并間隔添加樟腦粉（0.5g/m3）以防止毛鱗片結(jié)構(gòu)受損。
In feeding management, the proportion of green coarse feed needs to maintain 20% -25% of body weight (dry matter basis), and the feeding sequence prioritizes the selection of multi leaf forage (crude protein>18%) and root and stem feed (starch content<25%). Its unique feeding behavior can increase the absorption rate of VB12 in soft manure by 37%. The optimization of shearing cycle requires a balance between wool quality and yield: during the 75 day wool raising period, the proportion of premium wool reaches 42% (wool length ≥ 6cm), while during the 60 day cycle, although the annual yield increases by 8%, the proportion of secondary wool rises to 55%. The shearing operation should follow the spine splitting method, using curved scissors to maintain a 15 ° cutting angle. After shearing, the moisture content of the wool fibers should be controlled at 8% -12%. When storing, double-layer moisture-proof paper should be used and camphor powder (0.5g/m 3) should be added at intervals to prevent damage to the wool scale structure.
