摘要
本研究旨在对新疆南部地方品种绵羊平原型和田羊、山区型和田羊及卡拉库尔羊的17种生长发育指标进行检测分析,了解农区舍饲条件下新疆南部地方品种绵羊的基本生长发育情况。主要进行了2个品种、品系绵羊断奶后7个多月期间的17项生长指标的检测,通过SPSS 17.0统计软件分析其各项指标的差异显著性。结果表明:6月龄时,平原型和田羊与山区型和田羊间体高、尻长存在差异显著性(P<0.05),而后胸宽、尾长、尾宽、尾厚的差异极显著(P<0.01);山区型和田羊与卡拉库尔羊间前胸宽、后胸宽存在差异显著性(P<0.05);平原型和田羊与卡拉库尔羊间体重、胸围存在差异显著性(P<0.05),且前胸宽、后胸宽、尾长、尾宽、尾厚的差异极显著(P<0.01)。所检测各项指标的平均月增长量,平原型和田羊与山区型和田羊间体高存在差异显著性(P<0.05),而山区型和田羊与卡拉库尔羊间体高差异极显著(P<0.01);山区型和田羊与卡拉库尔羊管围存在差异显著性(P<0.05);平原型和田羊与卡拉库尔羊间尾厚存在差异显著性(P<0.05)。对于绵羊体重、体长、体高、胸围等生长发育规律的研究结果表明,平原型和田羊的生长发育与山区型和田羊以及卡拉库尔羊相比较在这些方面具有优势。
This research was analysis the seventeen growth indexes of plain Hetian sheep, mountain Hetian sheep and Kara-kul sheep in the shield. Samples were collected from 3 months old lamb after weaning. SPSS 17.0 was employed to statisticsthe differences among them. The results were as following, for the 6 months old lambs, the body high and buttock length hadsignificant differences (P〈0.05), while the metathorax wide, tail length, tail wide and tail thickness had higher significantdifferences between plain Hetian sheep and mountain Hetian sheep (P〈0.01). The protothorax wide and metathorax wide hadsignificant differences between mountain Hetain sheep and Karakul sheep (P〈0.05). The weight and across chest had signifi-cant differences (P〈0.05), while the protothorax wide, metathorax wide, tail length, tail wide and tail thickness had highersignificant differences between plain Hetian sheep and Karakul sheep (P〈0.01). For the average monthly increment of theseindexes, the body high had significant difference between plain Hetain sheep and mountain Hetain sheep (P〈0.05), while thebody high had higher significant difference between mountain Hetian sheep and Karakul sheep (P〈0.01). Differences of tailthickness between plain Hetain sheep and Karakul sheep were significant (P〈0.05). The results showed that plain Hetainsheep were much hetter than that of the mountain Hetain sheep and Karakul sheep in those indexes such as weight, bodylength, body high and across chest.
