Parameter untuk mengetahui hewan sapi sempurna setelah disembelih yaitu dengan melihat refleks kelopak mata dan atau waktu henti darah memancar. Menurut EFSA (2004) kematian merupakan suatu keadaan yang ditandai dengan respirasi fisiologis dan sirkulasi darah telah berhenti sebagai akibat dari pusat sistem tersebut di batang otak secara permanen kehilangan fungsi karena kekurangan oksigen dan energi. Waktu henti darah memancar merupakan indikasi bahwa jantung sudah tidak dapat memompa darah keluar dari tubuh karena tidak ada lagi asupan oksigen darah dalam jantung, sehingga hewan tersebut dapat dikatakan mati. Tujuan dari penelitian ini untuk menghitung waktu henti darah memancar pada penyembelihan sapi dengan metode pemingsanan dan tanpa pemingsanan yang dipotong di rumah potong hewan ruminansia besar (RPHRB), sehingga diperoleh data rataan waktu hewan mati sempurna. Tiga puluh ekor sapi Brahman Cross dibagi menjadi 2 kelompok perlakuan yaitu, sebanyak 15 ekor yang disembelih dengan pemingsanan (kelompok 1) dan sebanyak 15 ekor yang disembelih tanpa pemingsanan (kelompok 2). Waktu henti darah memancar dihitung sesaat setelah hewan disembelih sampai darah berhenti memancar. Hasil dari penelitian diperoleh rataan waktu henti darah memancar pada sapi yang dipingsankan sebelum disembelih adalah sebesar 3,02 menit dan rataan waktu henti darah memancar pada sapi yang disembelih tanpa pemingsanan adalah sebesar 2,13 menit. Selang waktu henti darah memancar antara sapi yang dipingsankan dengan sapi yang tidak dipingsankan sebelum disembelih adalah 53,4 detik. Waktu henti darah memancar dipengaruhi oleh perlakuan hewan sebelum pemotongan, yaitu dengan atau tanpa pemingsanan.Kata kunci: Pemingsanan, sapi, tanpa pemingsanan, waktu henti darah (The Perfect Cow Died after Slaughtered by Stunning and Non Stunning Methods According to Gushing Blood Downtime)Palpebra reflex and gushing blood downtime can be used as parameters to see animals death after slaughtered. Stop bleeding time was an indication that the heart is unable to pump blood out of the body due to no more oxygen in the blood of the heart, so that the cattle can be said has been dead perfectly. The aims of this study was to calculate the stop bleeding time of cattle slaughtered by stunning and non stunning methods, thus obtained the avaraging data of perfectly death time of animals. Thirty catlles’s Brahman Cross divided into two treatment groups, firstly 15 cattle’s were slaughtered by stunning method (group 1) and the second one 15 cattle’s were slaughtered by non stunning method (group 2). Blood gushing downtime was calculated immediately after the animal is slaughtered until the blood stops radiating. The results showed the average blood gushing downtime in cattles that were stunning before slaughtered is 3.02 minutes and the average time to stop blood gushing in cattles of non stunning group is 2.13 minutes. The interval blood gushing downtime between the cattles slaughtered by stunning and non stunning was 53.4 seconds. Blood gushing downtime was affected by the treatment of animals before they were slaughtered.Keywords: cattle, gushing blood downtime, non stunning, stunning.
