Abstract

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.

Abstract

Campylobacter spp. is a bacteria foodborne zoonotic agent that can infect humans and animals, especially birds. This bacteria can cause important problems in the public health since the beginning at the farm level, the level of retail and on the table. Poultry meat is the main source of contamination because the digestive tract of poultry is the predilection of Campylobacter jejuni. During this infection C. jejuni in poultry did not show typical clinical symptoms, making detection quite difficult to diagnose this disease at the farm level. Incidence infection of Campylobacter sp. in developed countries had 5-90%. Currently poultry production and consumption are predicted to still increase due to a high demand for low price protein. This research is conducted to determine the clinical and pathologic anatomy due to an infection of C. jejuni on chicken digestive tract. A total of 105-day-old chickens are divided into 3 groups, each consisting of 35 individuals. Group A was the control group (not infected) group B (infected with C. jejuni ATCC 33291), and group C (infected with field isolate of C. jejuni/C1). Infection of the chicken is done 0.5 ml peroral suspension concentration of104cfu/ml. Anova Duncan is used to analyze parameters of body weight, increase weight gain, feed consumption, FCR values. Kurskall Walis method used to analyze the parameters non-parametric form of the score changes in the macroscopic and microscopic intestinal and liver. Infection of C. jejuni changes the pathology anatomy of intestine i.e. hyperemia, enteritis and enteritis catharalis haemorrhagic. A microscopic change of intestinal is oedema,haemorrhage and infiltration of inflammatory cell. Changes of pathology anatomy liver are colour smeary, congesti, pale, fragile and necrotic. Microscopic changes of liver are degeneration and focal hepatic necrosis. Group observation infected by C. jejuni caused chicken cannot reach maximum body weight and can be detrimental to farmers because of increase of the value of the feed conversion ratio (FCR).

Abstract

Mastitis is udder inflammation that can be caused by the entry of pathogenic bacteria through the teat. One of the treatments that can prevent bacteria infection is teat dipping. This research was aimed to identify the effectof teat dipping after milking to the presence of pathogenic bacteria that cause subclinical mastitis (Staphylococcus aureus, Streptococcus agalactiae, and Escherichia coli) and the presence of pathogenic bacteria that cause subclinicalmastitis by quarter of udder. Milk samples were taken from normal lactation period of dairy cows, clinically healthy, and positive subclinical mastitis status when the intervention was applied. Sixty seven samples of quarters from 18dairy cows were identified to the presence of pathogenic bacteria that cause subclinical mastitis before teat dipping and at 1st, 2nd, and 3rd months after teat dipping. Identification of the presence of pathogenic bacteria was done byculturing samples on selective agar media. The presence of common pathogenic bacteria, Staphylococcus aureus, and Escherichia coli decreased significantly after teat dipping, while Streptococcus agalactiae and other pathogenicbacteria did not decrease significantly. The presence of pathogenic bacteria based on the quarter of udder did not show the significance difference. Application of teat dipping after milking was able to decrease the presence ofpathogenic bacteria that cause subclinical mastitis.
