為了方便大家，幫樓主整理了一下
一 人工養(yǎng)殖的主要品種及特征
(一)赤狐：體細長，四肢較短，嘴尖，尾長40～60cm，體長60～90cm，體高40～50cm.，體重5～8kg，尾部特別蓬松，毛色差異很大，標準者頭軀尾褐色，深者為赤色，四肢呈黑色，腹部顏色灰褐色，尾尖白色，耳背面黑色。
（二）銀黑狐：其外形與狗相似，嘴尖耳長，四肢細長，體長60～70cm，體高40～50cm，尾長40～50cm，體重5～6kg，全身被毛基本為黑色，底戎青灰色，襯托出銀白色而得名。其針毛毛尖黑色，靠近毛尖一小段為白色，基部一大段為灰黑色，尾端為白色，形成4～10cm的白尾尖。粗圓柱狀最好，圓錐狀次之。
（三）北極狐：整體比銀黑狐短小，嘴短而粗，耳小而圓，體形較胖。成年體長60～70cm，尾長25～30cm，體重5～6kg，有非常稠密的短絨和柔針毛，①白色北極狐隨季節(jié)不同毛色有變化，冬天白色，夏天變深色。②淺蘭北極狐終年都有較深毛色，是最有價值的狐。
二 生物學特性▲
（一）棲息地野生時棲居在森林，草原，丘陵，荒地和叢林，河流，溪谷，湖泊岸邊。常以天然木洞，土穴，墓地，石縫為穴。棲息地隱蔽程度較好。北極狐分布歐亞北美北部及北極洋地帶。生活在沿海，河流沿岸的島上，喜歡沼澤地。（二）食性狐以肉食為主也食些植物。野生狐主要以魚，蚌，蝦，蟹，昆蟲，蚯蚓，鼠，鳥，家禽，以及野生畜和家畜的，糞便為食，有時采食漿果，植物籽實根莖葉莖。（三）狐的習性 狐機警，多疑，狡猾，晝伏夜出。野生北極狐聚集而居曾發(fā)現(xiàn)過一個洞穴有集居20-30只種間生存斗爭非常劇烈，往往弱肉強食。狐抗寒能力強，不耐熱，喜歡干燥空氣清潔新鮮的環(huán)境生活。狐能沿峭壁爬行，會游泳，還能爬傾斜的樹。公母狐共同哺育后代，一年繁殖一次。（四）狐的換毛 成年狐每年換毛一次，正常在早春3～4月份，換毛順序是頭，前肢，頸，肩，背，體側(cè)，腹部，臀部與尾根部，一片一片脫落。新絨毛生長順序與脫毛順序相同，但到夏初停止生長。夏毛比冬毛陰暗稀短，在7～8月份時剩下沒有脫掉的粗長針毛大量脫落，以后針毛絨毛一起生長直至11月份形成冬季長而稠的被毛?？梢源蚱ぷ泻跎鷷r全身長滿稀短灰黑的胎毛并緊貼皮膚，隨仔狐日齡增大毛色變黑，30～40日齡時銀黑色仔狐在面部能見到白色銀毛露出，2～3月齡時銀毛在全身分布更明顯。北極狐10月份前基本是絨毛組成的毛皮。（五）壽命和天敵 銀黑狐一般可活10～12年，北極狐8～10年。繁殖年限銀黑狐5～6年，北極狐4～5年，最佳繁殖年齡3～4歲。其天敵有狼，猞猁，獵狗，猛禽等。
三 繁殖技術 ▲
（一）籠養(yǎng)狐性成熟時間：一般9～11月齡，公狐比母狐早，銀黑狐比北極狐早。（二）公狐性周期變化特點：公狐在非發(fā)情期（5-10月份）睪丸直徑5mm左右，質(zhì)地堅硬，附睪中沒有成熟精子陰囊布滿毛貼與腹側(cè)，外觀不明顯。秋分9月22-24日時開始發(fā)育，到小雪（11月下旬，11月22日-23日）期間睪丸直徑達到16～18mm，冬至（12月21-23日）后生長速度加快。1～2月初直徑可達2.5cm（比非發(fā)情期增大5倍）質(zhì)地松軟有彈性，附睪中有成熟精子。陰囊被毛稀疏松也下垂且明顯易見。公狐有性欲要求，可進行交配，配種期間60～90d始終有性欲，后一個月內(nèi)性欲逐漸降低，性情暴躁，有時撲咬母狐，不是對發(fā)情好而溫順的母狐也可達成交配，發(fā)情結束后睪丸很快萎縮，到5月份恢復到非發(fā)情期大小。幼齡公狐隨身體生長性器官逐漸成熟，以后性周期變化與成年公狐相同。（三）母狐性周期變化特點：卵巢大致在秋分時發(fā)育，到1月底2月上旬可有發(fā)育成熟的濾泡或卵子，整個發(fā)育期為1月中旬到4月中旬。交配后的母狐進入妊娠和產(chǎn)仔期，而未受妊的母狐又恢復到靜止期。狐同其他犬科動物一樣屬于季節(jié)性一次發(fā)情。
（四）狐發(fā)情時間：銀黑狐和赤狐1月中旬到3月中旬；北極狐2月中旬到4月中中旬。經(jīng)產(chǎn)母狐早于初產(chǎn)母狐；飼養(yǎng)條件好的早于飼養(yǎng)條件差的。（五）狐的交配時間：一般銀黑狐15～25min，北極狐20～30min，個別的狐1～2h。交配時間短的只見交配不出現(xiàn)連襠現(xiàn)象，這時可檢查母狐陰道內(nèi)是否有精子，從而確認是否交配成功；否則可找另一只公狐進行交配。（六）如何掌握控制公狐配種能力：一般1只公狐每天可交配2次，但每次間隔時間3～4h以上，因為公狐精子生成和性欲恢復很快。一般1只狐可配2-3只母狐。個別公北極狐可配8～9只母狐，公銀黑狐最多可配5～6只，若人工受精則更多。（七）如何解決公母狐擇偶現(xiàn)象：母狐進入發(fā)情期后逐漸有強烈的求偶欲，異性間非常和諧，從不發(fā)生咬斗現(xiàn)象。個別公母狐有挑選擇偶行為，不和諧之間互不理睬，有時發(fā)生咬斗，雖然已經(jīng)進入發(fā)情期但不發(fā)生交配行為，經(jīng)過更換配偶后馬上可達成交配，這是擇偶性強的表現(xiàn)。另外因為公母狐恐懼或被咬傷后暫時或長時間出現(xiàn)性欲抑制現(xiàn)象。公狐喪失配種能力，懼怕母狐，亂咬母狐；母狐雖已發(fā)情，但懼怕公狐，拒絕交配；以上情況可預先將發(fā)情母狐放入相配公狐相鄰的籠內(nèi)，相互熟悉，有助于形成和諧的配偶。（八）母狐發(fā)情鑒定方法：
1、外生殖器官檢查法：發(fā)情期母狐外生殖器腫脹呈圓形，顏色暗紅，有些母狐有紅色或黃色分泌物，可認為母狐進入發(fā)情期。2、放對試情：發(fā)情初期母狐有趨向異性的表現(xiàn)，可與試情公狐玩耍嬉戲，但拒絕交配。發(fā)情盛期，母狐性欲旺盛，翹尾與公狐交配。發(fā)情后期性欲減退，對公狐不理睬，一般難達成交配。3、行為觀察：發(fā)情母狐行動不安，徘徊運動增加，食欲減退，排尿頻繁，尿液較濃呈黃綠色，經(jīng)常舔舐外生殖器，發(fā)情旺盛期食欲廢絕，不斷發(fā)出求偶叫聲。發(fā)情后期活動逐漸趨于正常，食欲恢復，神經(jīng)安定。
（九）狐初配后為什么要進行復配：狐是自發(fā)排卵動物。母狐排卵一般在發(fā)情當天下午或第二天早晨。北極狐在發(fā)情后第三天才排卵，卵子不同時排出而是陸續(xù)排出。銀黑狐1～3d，北極狐5～7d，銀黑狐配2次以上，北極狐3～4次，有利于提高繁殖率。（十）妊娠期計算：銀黑狐50～61d，北極狐50～58d。（十一）產(chǎn)仔數(shù)與初生重：銀黑狐一胎平均5只，最多9只，初生重80～130g；北極狐一胎平均8只，最多22只，初生重60～90g。（十二）仔狐睜眼，出牙，吃食，斷奶時間：出生后14～16d睜眼出牙，20～25d開始吃飼料，30d以后食量猛增，應抓緊人工補飼，出生后45～60d進行人工斷奶分窩。（十三）正常母狐帶仔狐數(shù)：銀黑狐6～9只，北極狐10～11只，每胎產(chǎn)仔狐多的應代養(yǎng)出去。
四．狐的日糧標準 不同飼養(yǎng)時期日糧標準不同
飼養(yǎng)時期 魚粉 乳類 谷物 蔬菜 酵母 骨粉
5～12月 41～50 7 6～9 20 1.5 1～1.5
1～2月 46～54 7 5～8 15 1.5 1～1.5

五．狐的疾病與防治
（一）犬瘟熱
1、易感動物：狐、狗、狼、鼬、貂、貍、貉等。2、病原及癥狀：該病是犬瘟熱病毒引起的一種高度接觸性傳染病，往往伴有細菌感染如大腸桿菌，葡萄球菌，鏈球菌，沙門氏桿菌等，繼發(fā)感染所致的敗血癥，表現(xiàn)為發(fā)熱，眼睛、眼、鼻、呼吸道和消化道黏膜有炎癥，也叫潰瘍卡他。出現(xiàn)拒食，嘔吐，下痢，皮疹，還有神經(jīng)癥狀，如肌肉痙攣，共濟失調(diào)，昏迷抽搐，四肢麻痹癱瘓，3、防治辦法：定期進行犬瘟熱疫苗接種，適當結合對癥治療和血清治療。
（二）狐病毒性腸炎
1、病原與癥狀：為細小病毒。曲型癥狀為劇烈腹瀉，頑固性下痢并伴有高熱40～41℃，死前腹脹，鼻口流淡紅色血水。2、防治辦法：定期進行細小病毒滅活疫苗接種并結合癥狀用抗菌素防止并發(fā)癥，如：慶大、氯霉素。
