| 中文摘要: |
| 为研究雷州黑鸭血液生化性状及其与体尺和肉质性状间的关系，随机选取12只300日龄雷州黑鸭（公、母各半）进行测定分析。结果显示：谷丙转氨酶（GPT）与骨盘宽呈显著性正相关，乳酸脱氢酶（LDH）与肌肉粗蛋白含量与半潜水长均呈极显著相关，与蒸煮损失率与胸宽呈显著相关，肌肉pH、胸宽与骨盘宽均呈显著性正相关，胸宽和骨盘宽均和半潜水长呈极显著正相关。典型相关分析结果为：血液生化性状跟体尺性状和肉品质性状间的第1个典型相关系数分别为0.874（P<0.05）、0.901（P<0.05），分别占2组性状总相关信息的81.2%和90.6%，体尺性状和肉品质性状间的第1个典型相关系数为0.901（P<0.05），占2组性状总相关信息的75.4%。结果表明，在3组性状中LDH、胸宽、半潜水长、肌肉pH和肌肉粗蛋白含量起主要作用，血液生化性状和肉质性状在3组性状间的相关性最高。 |

| To study the relation among blood biochemical traits, meat quality and body measurements traits of Leizhou black duck, 12 300-day-old Leizhou black ducks ( 6, 6) were randomly selected for analysis. The results showed that, GPT and width of pelvis had a significant positive correlation （P<0.05）, LDH with the content of crude protein in muscle and the length from beak to hip had a extremely significant correlation（P<0.01）, LDH with the cooking lose rate and chest width had a significant correlation（P<0.05）, the pelvis width with the muscle pH and chest width had a significant positive correlation （P<0.05）, the length from beak to hip with the chest width and pelvis width had a extremely significant positive correlation （P<0.01）. The results of canonical correlation analysis showed that the first canonical correlation coefficient between blood biochemical traits and body measurements traits (0.874) was significant and expressed 81.2% of total correlation. The first canonical correlation coefficients between blood biochemical traits and meat quality (0.901), as well as between body measurements traits and meat quality (0.901)were significant, which constituted 90.6% and 75.4% of total correlation, respectively. The analysis indicated that main traits for the canonical correlation coefficients were the LDH, chest width, length from beak to hip, muscle pH and contents of crude protein in muscle, the blood biochemical traits and meat quality had the biggest correlation. |
