Burung kuntul kerbau (Bubulcus ibis) merupakan spesies burung air dari famili Ardeidae yang berperan menjaga keseimbangan ekosistem di habitatnya. Kehadiran burung ini mencerminkan kesehatan lingkungan dan populasinya. Kondisi kesehatan burung kuntul kerbau dapat dikaji melalui pemeriksaan profil darah merah. Penelitian ini bertujuan untuk mengetahui profil darah merah burung kuntul kerbau jantan dan betina di Desa Lambada Lhok, Kecamatan Baitussalam, Kabupaten Aceh Besar. Burung kuntul kerbau yang digunakan berjumlah enam ekor yang terdiri dari tiga ekor jantan dan tiga ekor betina sehat secara klinis dengan berat badan 250–350 gram. Pemeriksaan jumlah eritrosit dilakukan menggunakan hemositometer, kadar hemoglobin ditentukan menggunakan metode Sahli, nilai hematokrit diukur dengan metode mikrohematokrit, serta indeks eritrosit dihitung menggunakan rumus Wintrobe. Rata-rata pemeriksaan menunjukkan nilai eritrosit 2.60 ± 0.05 × 106/mm3, hemoglobin 16.28 ± 0.49 g/dl, hematokrit 42.83 ± 0.75%, MCV 164.34 ± 1.47 fl, MCH 62.46 ± 1.11 pg, dan MCHC 38.01 ± 0.59 g/dl. Hasil pemeriksaan pada jantan menunjukkan nilai eritrosit 2.65 ± 0.02 × 106/mm3, hemoglobin 16.56 ± 0.56 g/dl, hematokrit 43.33 ± 0.57%, MCV 163.51 ± 1.26 fl, MCH 62.51 ± 1.68 pg, dan MCHC 38.22 ± 0.82 g/dl, sedangkan pada betina diperoleh nilai eritrosit 2.56 ± 0.05 × 106/mm3, hemoglobin 16.00 ± 0.20 g/dl, hematokrit 42.33 ± 0.57%, MCV 165.16 ± 1.33 fl, MCH 62.42 ± 0.51 pg, dan MCHC 38.01 ± 0.59 g/dl. Dapat disimpulkan bahwa profil darah merah yang diperoleh dari penelitian dapat dijadikan data dasar pada burung kuntul kerbau dengan jenis kelamin diketahui tidak memberikan pengaruh yang signifikan terhadap profil darah merah jantan dan betina (p > 0.05).

The cattle egret (Bubulcus ibis) is a species of waterbird belonging to the family Ardeidae that plays an important role in maintaining ecosystem balance within its habitat. The presence and population of this species reflect environmental health. The health status of cattle egrets can be assessed through the examination of red blood cell profiles. This study aimed to determine the red blood cell profiles of male and female cattle egrets in Lambada Lhok Village, Baitussalam District, Aceh Besar Regency. A total of six clinically healthy cattle egrets were used in this study, consisting of three males and three females with a body weight of 250-350 grams. Erythrocyte counts were determined using a hemocytometer, hemoglobin levels were measured using the Sahli method, hematocrit values were assessed using the microhematocrit method, and erythrocyte indices were calculated using the Wintrobe formula. The mean values obtained were erythrocyte count of 2.60 ± 0.05 × 10⁶/mm³, hemoglobin concentration of 16.28 ± 0.49 g/dL, hematocrit of 42.83 ± 0.75%, mean corpuscular volume (MCV) of 164.34 ± 1.47 fL, mean corpuscular hemoglobin (MCH) of 62.46 ± 1.11 pg, and mean corpuscular hemoglobin concentration (MCHC) of 38.01 ± 0.59 g/dL. The results for male cattle egrets showed erythrocyte counts of 2.65 ± 0.02 × 10⁶/mm³, hemoglobin levels of 16.56 ± 0.56 g/dL, hematocrit values of 43.33 ± 0.57%, MCV of 163.51 ± 1.26 fL, MCH of 62.51 ± 1.68 pg, and MCHC of 38.22 ± 0.82 g/dL. Meanwhile, female cattle egrets exhibited erythrocyte counts of 2.56 ± 0.05 × 10⁶/mm³, hemoglobin levels of 16.00 ± 0.20 g/dL, hematocrit values of 42.33 ± 0.57%, MCV of 165.16 ± 1.33 fL, MCH of 62.42 ± 0.51 pg, and MCHC of 38.01 ± 0.59 g/dL. It can be concluded that the red blood cell profiles obtained in this study can serve as baseline hematological data for cattle egrets, and that sex does not have a significant effect on the red blood cell profiles of male and female cattle egrets (p > 0.05).
