Di Indonesia, forensik veteriner belum mendapat perhatian yang memadai, sehingga perlu ditingkatkan pengembangannya. Penelitian forensik veteriner ini bertujuan memberikan gambaran histopatologi hati ayam broiler sampai 48 jam setelah kematian (post mortem). Sebanyak 75 ekor ayam broiler berumur tujuh hari dieutanasia dengan cara dislokasi cervical, kemudian dibagi menjadi 25 kelompok yang tiap kelompok terdiri atas 3 ekor. Setiap dua jam kadaver ayam dinekropsi, organ hati dikoleksi untuk dibuat sediaan histopatologi dan diwarnai Hematoksilin-Eosin (HE). Histopatologi jaringan hati dianalisis menggunakan software ImageJ dan hasilnya diuji dengan uji Pearsons. Pembusukan dimulai pada jam ke-18 berupa penurunan jumlah inti sel hepatosit, jam ke-22 terjadi peningkatan jarak hepatosit dan jam ke-20 ditemui keberadaan bakteri pembusuk. Jumlah inti sel hepatosit, jarak antar sel, dan keberadaan bakteri pembusuk mempunyai hubungan kuat hingga sangat kuat dengan waktu, sehingga dapat dijadikan penentu waktu kematian (PMI). Warna sitoplasma hepatosit memiliki hubungan yang lemah dengan waktu sehingga tidak dapat digunakan sebagai penentu PMI. Peubah jumlah inti hepatosit, jarak antar hepatosit, dan keberadaan bakteri dapat dijadikan sebagai sumber acuan dalam forensik veteriner. In Indonesia, veterinary forensics has not received adequate attention, so its development needs to be improved. This veterinary forensic study aims to provide histopathological changes of the liver of broiler chickens up to 48 hours after death. A total of 75 broilers aged seven days were euthanized by cervical dislocation, then divided into 25 groups, each group consisting of 3 birds. Every two hours broiler cadaver necropsied, the liver was collected for histopathological preparation and stained with Hematoxylin-Eosin (HE). Histopathological changes in liver tissue were analyzed using ImageJ software, and the results were analyzed using the Pearsons' method. Putrefaction begins at the 18th hour with a decrease in the number of hepatocyte cell nuclei, at the 22nd hour is an increase in distance of hepatocyte, and at the 20th hour is the presence of putrefactive bacteria. The number of hepatocyte cell nuclei, the distance between hepatocytes, and the presence of bacteria have a strong and too strong relationship with time that they can use as determinants of post mortem interval (PMI). The color of the hepatocyte cytoplasm has a weak relationship with time, so it cannot use as a determinant of the post mortem interval. The number of hepatocyte nuclei, the distance between hepatocytes, and the presence of bacteria can use as a reference source in veterinary forensics.
