The objective of the present study was to determine the associations between the FAMACHA© score, body condition score (BCS) and several haematological parameters of Pelibuey ewes. In total, 52 clinically healthy Pelibuey ewes were evaluated in this study. A blood sample was collected from each animal to determine haematological variables. The BCS was evaluated on a scale of 1 to 5 and subsequently grouped into four categories: (1) < 1.5, (2) 2.0-2.5, (3) 3.0-3.5 and (4) > 4.0. The coloration of conjunctival mucosa was evaluated using the FAMACHA© system. The analysed haematological parameters were red blood cell (RBC) count, haemoglobin (HGB), haematocrit (HCT), mean corpuscular volume (MCV), mean corpuscular haemoglobin (MCH), mean corpuscular haemoglobin concentration (MCHC), red blood cell distribution width standard deviation (RDW-SD) and red blood cell distribution width coefficient of variation (RDW-CV). A descriptive statistical analysis was performed, and the Pearson correlation coefficients between variables were estimated. Haematological parameters were analysed with one-way analyses of variance, and the Tukey test was applied when significant differences were detected. The FAMACHA© score was only associated with MCHC (r = - 0.30, P < 0.05). The haematological parameters of RBC count, HCT, RDW-SD and RDW-CV statistically differed among BCS groups. The BCS was associated with RBC count, HCT, RDW-SD and RDW-CV, with r values ranging from 0.35 to 0.48. The haematological values were similar to those reported in ewes from Iran and Iraq. Hence, the optimization of the BCS calculation of Pelibuey ewes can generate association tables with haematological parameters to aid in the sanitary and feeding management of sheep.
本研究旨在确定 FAMACHA© 评分、体况评分（BCS）与 Pelibuey 母羊的几项血液学参数之间的关系。本研究共评估了 52 只临床健康的 Pelibuey 母羊。从每只动物采集血样以确定血液学变量。BCS 评分为 1 至 5 分，并随后分为四个类别：（1）<1.5、（2）2.0-2.5、（3）3.0-3.5 和（4）>4.0。使用 FAMACHA© 系统评估结膜黏膜的着色。分析的血液学参数包括红细胞（RBC）计数、血红蛋白（HGB）、血细胞比容（HCT）、平均红细胞体积（MCV）、平均红细胞血红蛋白（MCH）、平均红细胞血红蛋白浓度（MCHC）、红细胞分布宽度标准差（RDW-SD）和红细胞分布宽度变异系数（RDW-CV）。进行描述性统计分析，并估计变量之间的 Pearson 相关系数。对血液学参数进行单因素方差分析，当检测到显著差异时应用 Tukey 检验。FAMACHA© 评分仅与 MCHC 相关（r = -0.30，P < 0.05）。RBC 计数、HCT、RDW-SD 和 RDW-CV 等血液学参数在 BCS 组之间存在统计学差异。BCS 与 RBC 计数、HCT、RDW-SD 和 RDW-CV 相关，r 值范围为 0.35 至 0.48。血液学值与伊朗和伊拉克母羊的报告值相似。因此，优化 Pelibuey 母羊 BCS 的计算可以生成与血液学参数相关的关联表，以帮助绵羊的卫生和饲养管理。
