        提高獺兔毛皮質(zhì)量八種方法

        發(fā)布日期:2014-08-09 來源:http://m.parmwkd.cn 發(fā)布人:admin

        一、獺兔剝皮季節(jié)剝皮季節(jié)對青年獺兔影響不大,但是對成年兔、老齡兔則影響較大。一般以冬皮品質(zhì)更佳,因此,成年兔或老年兔的剝皮季節(jié)更好選擇在秋末或冬季,要少剝春皮,禁剝夏皮。
        First, Rex rabbit skin peeling season season has little influence on the young Rex Rabbit, but for adult rabbits, aged rabbits had a greater effect. General to the winter skin quality best, therefore, the elderly adult rabbit or rabbit peeling season best choice in late autumn or winter, spring less peeling skin, no peeling charpy.
          二、宰殺年齡一般來講,成年兔皮的質(zhì)量比幼齡兔皮和老齡兔皮要好。4月齡前幼齡兔的皮,因絨毛不夠豐滿,胎毛褪換未盡,毛粗絨稀,板質(zhì)輕薄,商品價值不高。5~6月齡壯年兔的皮,絨毛濃密,色澤光潤,板質(zhì)結(jié)實(shí),厚薄適中,質(zhì)量更佳。老齡兔皮板質(zhì)厚硬、粗糙,絨毛空疏、枯燥,色澤暗淡,商品價值很低,而且毛皮品質(zhì)有隨產(chǎn)子胎次增加而逐漸下降的趨勢。
        Two, slaughter age generally speaking, quality in adult rabbit than the young rabbit skin and aging skin. Young rabbit skin in April before the age of the villi, not full, lanugo faded change not, rough hair thin, thin plates, commodity value is not high. 5 ~ June age adult rabbit skin, hair thick, bright luster, plate quality firm, thickness is moderate, the best quality. Old rabbit skin plate thick hard, rough, villous empty, dull, dark in color, commodity value is very low, and fur quality decreases with the increasing trend of birth parity.
          三、種質(zhì)因素種質(zhì)因素是決定獺兔毛質(zhì)量的關(guān)鍵因素之一,如品種遺傳性不穩(wěn)定,除出現(xiàn)異色個體外,其后代被毛中還極易出現(xiàn)雜色、色斑、色帶、銹色和吊肚等缺陷
        Three, genetic factors genetic factors is a key factor that decides the rabbit hair quality, such as genetic instability, in addition to Harmonia in vitro, the offspring by Mao also prone to noise, stains, rust colored ribbon, and hanging belly defects
          四、飼養(yǎng)管理飼養(yǎng)管理對毛皮品質(zhì)影響很大。飼料中蛋白質(zhì)不足往往會導(dǎo)致短芒和引起毛纖維強(qiáng)度下降;維生素和微量元素缺乏,常會導(dǎo)致獺兔被毛退色、脆弱,甚產(chǎn)生脫毛現(xiàn)象。另外,營養(yǎng)不良往往會導(dǎo)致獺兔生長受限,體型瘦小,致使皮板面積不符合等級要求。

        Effect four, feeding and management of feeding management on the quality of fur. Lack of protein in feed often leads to short awns and decrease the strength of wool fiber; vitamins and trace element deficiency, often results in rabbit hair fade, fragile, and even have depilation. In addition, malnutrition will often result in Rex rabbit growth restriction, thin body, the leather area does not meet the requirements of.
          五、加工因素加工不當(dāng)常會產(chǎn)生刀洞、歪皮、缺材、撐板和折裂傷、皺縮板等,嚴(yán)重影響獺兔毛皮品質(zhì)。刀洞是由于宰殺剝皮技術(shù)不當(dāng)造成的破殘;劃破皮板未成破洞的稱“描刀”。“描刀”深度不及皮板厚度1/2的影響不大,超過1/2的影響較大,制裘后可能出現(xiàn)孔洞。
        Five, the processing factors of improper processing, often produces knife hole, crooked skin, lack of material, support plate and folding laceration, shrinkage plate, seriously affecting the quality of Rex Rabbit fur. Knife hole is due to improper peeling technology were broken; pierced the skin plate without hole called "draw knife". "Little impact draw knife" depth than skin plate thickness 1/2, affecting more than 1/2 large, fur may occur after the hole.
          六、貯存條件毛皮因貯存不當(dāng),常會出現(xiàn)陳皮、煙熏、受悶、霉?fàn)€、蛀等現(xiàn)象,嚴(yán)重影響毛皮質(zhì)量。
        Six, storage conditions fur because of improper storage, often dried tangerine peel, smoked, stifle, mildew, moth phenomenon seriously affect the center, fur quality.
          七、性別影響在其他條件相同的情況下,性別對獺兔毛皮品質(zhì)也有明顯的影響。4~5月齡宰殺的公兔皮一般要比母兔厚,被毛更粗,毛絨更稀,板質(zhì)更為松弛,缺乏彈性,故公兔的毛皮質(zhì)量差于母兔。但母兔毛皮的品質(zhì)隨產(chǎn)子胎次的增加而明顯下降,產(chǎn)子胎次越多,毛皮品質(zhì)越差
        Seven, the gender effect in the other under the same conditions, gender has significant impact on the quality of Rex Rabbit fur. From 4 to May were slain male rabbit than female rabbit hair more thick, coarse, plush more dilute, the plate more relaxation, lack of flexibility, so the male rabbit fur quality is poor in female rabbits. But the mother rabbit fur quality decreased with increasing parity and birth, birth, parity number, fur quality worse
          八、個體大小獺兔的個體越大,則皮張面積就越大,毛皮等級則相應(yīng)高些
        Eight, individual size of Rex rabbit the greater the individual, then the skin area is larger, the higher level of fur
