This study evaluated the variation in the prevalence of endoparasitoses and their impact on body condition and blood values of sheep of the Morada Nova breed. A total of 138 ewes were examined for their morphology (body weight, BW; body condition score, BCS), parasitology (faecal egg count, FEC; Famacha© score; coproculture), hematology (red blood cell count,RBC); hemoglobin concentration, HE; packet cell volume, PCV; mean corpuscular volume, MCV,; mean corpuscular hemoglobin, MCH; mean corpuscular hemoglobin concentration, MCHC; leukocytes, WBC) and serum biochemistry (glucose, cholesterol, triglycerides, urea, creatinine, total protein, albumin, globulin, AST and ALT). Overall the animals presented higher BW and BCS in the months of September and December, however, with high FEC, in addition to a large number of animals with Famacha score 4 and 5. The results showed that the main hematophagous worm affecting the sheep, the genus Haemonchus ssp, appeared in a greater proportion (30-71.66%) than the other worms in all months of the study, except in March. About 30% of the hematological values found in the study are outside the reference ranges for suable sheep e 45.50% for serum biochemistry. These findings demonstrate the most healthy period of the year was from March to June for endoparasites control, however, in the months of September and December the animals showed better performance measures.
本研究评估了内寄生虫病患病率的变化及其对摩拉达诺瓦品种绵羊身体状况和血液值的影响。共对138只母羊进行了形态学（体重、BW；身体状况评分、BCS）、寄生虫学（粪便虫卵计数、FEC；Famacha©评分；粪便培养）、血液学（红细胞计数、RBC）、血红蛋白浓度、HE、血细胞压积、PCV、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、白细胞、WBC）和血清生化（葡萄糖、胆固醇、甘油三酯、尿素、肌酐、总蛋白、白蛋白、球蛋白、AST和ALT）检查。总体而言，这些动物在9月和12月体重和身体状况评分较高，但粪便虫卵计数也高，此外还有大量动物的Famacha评分为4分和5分。结果表明，在研究的所有月份中，除3月外，影响绵羊的主要吸血蠕虫血矛线虫属出现的比例（30%-71.66%）高于其他蠕虫。研究中发现约30%的血液学值超出了适养绵羊的参考范围，血清生化值超出参考范围的比例为45.50%。这些发现表明，一年中内寄生虫控制最健康的时期是3月至6月，然而，在9月和12月，这些动物的性能指标表现更好。
