本試驗之目的為利用腦下垂體特異性轉錄因子(pituitary transcription factor, POU1f1)的基因型，對10頭母努比亞山羊背最長肌的肉質表現進行評估，肉質表現包括物理性質的色澤L a, b值、保水性、蒸煮失重，韌度及硬度與化學性質的胺基酸與脂肪酸分析。初步結果：3頭POU1f1基因型CT之母努比亞山羊，其平均屠宰體重與日齡分別為48.3± 3.0 kg與462.3± 55.4日，而7頭POU1f1基因型CC之母努比亞山羊，其平均屠宰體重與日齡分別為44.6± 3.5 kg與421.1± 25.1日，在平均屠宰體重與日齡性狀上，兩者無顯著差異，化學性質亦無顯著差異。物理性質在色澤 a, b值、保水性、蒸煮失重等性狀，POU1f1基因型CT的個體都顯著低於CC個體，綜合上述結果顯示POU1f1 基因型對母努比亞山羊肉質性狀有影響，可供未來努比亞山羊基因選種之參考。
關鍵語：努比亞羊、肉質性能、基因型

The aim of this study was to apply the genotypes of pituitary transcription factor (POU1f1) genes to evaluate its relationship with meat quality performance of Longissimus muscle from 10 female Nubian goats. Meat performance includes the physical properties of color L a, b value, water retention rate, cooking weight loss, toughness and hardness, and the chemical properties of analysis in amino acid and fatty acid. The preliminary results, the average slaughter weight and age of 3 head female Nubian goats with POU1f1 CT were 48.3 ± 3.0 kg and 462.3 ± 55.4 days, respectively. While the average slaughter weight and age of 7 head female Nubian goats with POU1f1 CC were 44.6 ± 3.5 kg and 421.1 ± 25.1 days, respectively. There was no significant difference between the two groups on the average slaughter weight and age. There was also no significant difference between the two groups in the chemical properties of analysis in amino acid and fatty acid. Individuals with genotype POU1f1 CT were significant lower than with POU1f1 CC in the following physical property traits: color a, b value, water retention rate, cooking weight loss. The results are potentially useful in meat quality selection program for Nubian goat farmer in the future.
