長毛兔因具有極其發達的消化（huà）係統，因此形（xíng）成了獨（dú）特的（de）消化特點。

Long haired rabbits have unique digestive characteristics due to their extremely developed digestive system.

對粗纖維的消化率較高：長（zhǎng）毛兔屬單胃草食動物（wù），消化（huà）道長而複雜，容積很大，依靠盲腸中的微生物和發達的（de）球囊組織，能有效地利用低（dī）質高纖維飼料。據試驗，在長毛兔日糧中供 給適量的（de）粗纖維飼料，對長毛兔的健康是有益無害的，可刺激腸道蠕動，促進正常的消化、吸收功能。相反，如果日糧（liáng）中粗纖維含量過低，則可引起腸道蠕動減慢，內容物（wù）滯留時間延長，發酵變質，誘發有害細菌大量繁殖，引起腸（cháng）炎、腹瀉，甚（shèn）死亡。

The digestion rate of crude fiber is relatively high: The long haired rabbit belongs to the monogastric herbivorous animal, with a long and complex digestive tract and a large volume. It relies on the microorganisms in the cecum and developed balloon tissue to effectively utilize low-quality and high fiber feed. According to experiments, providing an appropriate amount of coarse fiber feed in the diet of long haired rabbits is beneficial and harmless to their health, can stimulate intestinal peristalsis, and promote normal digestion and absorption functions. On the contrary, if the crude fiber content in the diet is too low, it can cause slow intestinal peristalsis, prolonged retention time of contents, fermentation and spoilage, induce the proliferation of harmful bacteria, cause enteritis, diarrhea, and even death.

能充分（fèn）利（lì）用粗飼料中的蛋白質（zhì）:據試驗，長毛兔不僅對（duì）青粗飼（sì）料中的蛋白（bái）質有較高的（de）消化率，而且對低（dī）質飼料中的蛋白質有很強的消化利用能力。

Being able to fully utilize the protein in roughage: According to experiments, long haired rabbits not only have a high digestion rate for protein in green roughage, but also have strong digestion and utilization ability for protein in low-quality feed.

能耐受（shòu）口糧中的高鈣比例：長毛兔對日糧中的（de）鈣、磷比例要求不像其他畜禽那樣（yàng）嚴格。試驗表明，長毛兔日糧中的含磷請不（bú）宜過高，隻有鈣、磷比例為2:1以下時（shí），才能忍受高水平磷，過（guò）量的磷（lín）由糞尿排出（chū）體外。日糧中含磷（lín）量（liàng）過髙(超過1%時（shí）)，還會降低飼料（liào）的（de）適口性，影響長毛兔的采食量。

Can tolerate high calcium ratioses in the diet: Long haired rabbits do not have as strict requirements for calcium and phosphorus ratioses in the diet as other livestock and poultry. Experiments have shown that the phosphorus content in the diet of long haired rabbits should not be too high. Only when the ratio of calcium to phosphorus is below 2:1 can high levels of phosphorus be tolerated, and excessive phosphorus is excreted from the body through feces and urine. If the phosphorus content in the diet is too high (exceeding 1%), it will also reduce the palatability of the feed and affect the feed intake of long haired rabbits.

兔毛有（yǒu）一定的生長期，當兔毛生長到成（chéng）熟末期，毛根（gēn）底部（bù）逐漸變細而脫落，新毛開始生長，這種換毛過程稱為兔毛的脫換，年齡性換毛：年齡性換毛指幼兔而言。仔（zǎi）兔初生時無毛，一般在（zài）45日（rì）齡開始長（zhǎng）出細毛，到30日齡左右乳（rǔ）毛全部長成。生長發育正常（cháng）的幼兔，次（cì）年齡性換毛是在（zài）30100日齡，第（dì）二次（cì）年齡性（xìng）換毛是在130190日（rì）齡（líng）。在6.57.5月齡以後的換毛規（guī）律與成年兔一樣（yàng）。季節性換毛:季節（jiē）性換毛指成年（nián）兔而言。在正常情況下，成年兔（tù）每年春（chūn）秋兩季各換毛1次。春季換毛在34月份進行，由於此（cǐ）時（shí）飼料豐富，代謝旺盛，所以（yǐ）兔毛生長較快，換毛期較短；秋季換毛在89月份進行，由於飼料變換，毛囊代謝功能減弱（ruò），所（suǒ）以兔（tù）毛生長較慢，換毛期較長。

Rabbit hair has a certain growth period. When rabbit hair grows to the end of maturity, the bottom of the hair roots gradually becomes thinner and falls off, and new hair begins to grow. This process of hair exchange is called rabbit hair exchange. Age related hair exchange refers to young rabbits. When a young rabbit is born, it is hairless and usually begins to grow fine hair at 45 days of age. By around 30 days of age, all the milk hair has grown. For young rabbits with normal growth and development, the first age related hair change is at 30100 days old, and the second age related hair change is at 130190 days old. The hair changing pattern after 6.57.5 months of age is the same as that of adult rabbits. Seasonal shedding: Seasonal shedding refers to adult rabbits. Under normal circumstances, adult rabbits change their fur once a year in spring and autumn. Spring hair changing takes place in April. Due to the abundant feed and vigorous metabolism at this time, rabbit hair grows faster and the hair changing period is shorter; Autumn hair changing takes place in August. Due to changes in feed, the metabolic function of hair follicles is weakened, resulting in slower growth of rabbit hair and a longer hair changing period.
