【摘要】:為了研究被毛類型對(duì)白絨山羊重要經(jīng)濟(jì)性狀的影響,試驗(yàn)通過對(duì)毛長(zhǎng)測(cè)量值進(jìn)行數(shù)據(jù)分析后分成9組,利用SAS9.0軟件GLM以及Duncan’s多重比較方法,研究其對(duì)重要經(jīng)濟(jì)性狀的影響。結(jié)果表明:白絨山羊的絨厚、產(chǎn)絨量、抓絨后體重、絨長(zhǎng)、毛細(xì)、絨細(xì)等性狀均隨毛長(zhǎng)的增加呈不同程度的增長(zhǎng)趨勢(shì),且差異極顯著(P0.01)。毛長(zhǎng)對(duì)絨細(xì)的影響不及對(duì)其他性狀的影響顯著;而毛長(zhǎng)對(duì)產(chǎn)絨量的影響關(guān)系較為復(fù)雜,即被毛或長(zhǎng)或短兩個(gè)極端表現(xiàn)型的個(gè)體產(chǎn)絨量更大,且越趨于極端型,產(chǎn)絨量越高,處于兩個(gè)極端表現(xiàn)型之間的個(gè)體產(chǎn)絨量最低。將內(nèi)蒙古白絨山羊群體的被毛類型按其毛長(zhǎng)測(cè)量值分為三個(gè)類型,即1~3分組(毛長(zhǎng)≤13 cm)的白絨山羊?yàn)槎堂?4~6分組(13 cm毛長(zhǎng)≤22 cm)的白絨山羊?yàn)橹虚g型,而7~9分組(毛長(zhǎng)22 cm)的白絨山羊?yàn)殚L(zhǎng)毛型。
[Abstract]:In order to study the effect of coat type on important economic characters of white cashmere goat, the experiment was divided into 9 groups by analyzing the data of wool length measurement, and using SAS9.0 software GLM and Duncan's multiple comparison method. To study its influence on important economic characters. The results showed that the cashmere thickness, cashmere yield, weight after cashmere grabbing, velvet length, capillary size and velvet fineness of white cashmere goats increased with the increase of wool length, and the difference was very significant (P0.01). The effect of wool length on velvet fineness was less significant than that on other traits. The effect of wool length on the yield of wool is more complicated, that is, the individual with two extreme phenotypes of wool or length or short is larger, and the more extreme type, the higher the yield of wool, and the lowest amount of individual cashmere is in the middle of the two extreme phenotypes. The coat types of Inner Mongolia white cashmere goats were divided into three types according to the measured value of wool length. The white cashmere goats divided into 1 and 3 groups (wool length 鈮,
