Abstract
Complex respiratory disease in the calf (enzootic calves pneumonia) is a complex respiratory disease (bovine respiratory disease complex/BRDC) caused by co-infection with viral, bacterial or fungal pathogens. Granulomatous pneumonia is one of the dominant lesions in BRDC that characterizes the infection of Mycoplasma bovis, a bacterium that is very strong against phagocytosis of immun cells. This study aims to determine the presence of risk factors associated with the incidence of granulomatous pneumonia. This study used secondary data from Laboratory of Pathology in Balai Veteriner Lampung, Sample collection in 2015-2017 period from one of the breeding farm in Lampung. Data is processed by calculating frequency, tables and logistic regression in Epi-info tools. The frequency of granulomatous pneumonia at the age of pre weaning and weaning was 63.06% and 36.94%, breed Wagyu and Brahman cross (76.12% and 23.88%), as well as males and females (61.01% and 38.99%). The results of measurements with Epi-info show that the age factor (Odds ratio = 2.16, 95% CI = 1.51-3.09) and breeds (Odds ratio = 1.52, 95% CI = 1.003-2.31) were associated with the incidence of granulomatous pneumonia. Based on the results of research that Wagyu calf and weaning age are more at risk of granulomatous pneumonia.

Summary
Penelitian ini menggunakan data sekunder laboratorium patologi, organ paru pedet berasal dari breeding sapi potong yang mati karena peyakit pernafasan dengan variasi umur, jenis kelamin, dan breed. Data sampel dan hasil pengujian histopatologi yang disajikan berisi nomor identitas hewan, breed, jenis kelamin dan umur serta deskripsi diagnose histopatologi. Data tersebut kemudian diolah menggunakan tools Epi-info untuk mengukur derajat asosiasi masing masing faktor terhadap kejadian pneumonia granulomatosa. Pengolahan data pertama dengan menghitung fekuensi masing masing faktor (umur, jenis kelamin, dan breed) terhadap pneumonia granulomatosa. Ada tidaknya asosiasi masing masing faktor (umur, breed, jenis kelamin) terhadap kejadian pneumonia granulomatosa dihitung menggunakan Tabel tools Epi-info. Definisi kejadian pneumonia granulomatosa adalah gambaran hisropatologi paru pedet yang terlihat adanya sentra nekrosa berisi hancuran sel sel mati (debris), berwarna eosinofilik, dikelilingi oleh sel radang netrofil, makrofag dan jaringan ikat (Zachary, 2017). Pedet dilakukan penyapihan pada umur 90 hari, pedet pra sapih berumur kurang dari 90 hari
