Judul: Incidence of Fasciolosis and Paramphistomosis in Beef Cattle of North Sumatra Province from 2019-2020
Abstrak: Fasciolosis dan paramphistomosis adalah penyakit yang disebabkan oleh parasit cacing yang menyerang hati dan rumen dimana penularannya dapat melalui siput. Penyakit tersebut dapat menyebabkan kerugian baik dari segi kesehatan maupun ekonomi. Penelitian ini bertujuan menganalisis kejadian fasciolosis dan paramphistomosis serta menghitung kenaikan populasi pada sapi potong di Provinsi Sumatra Utara. Data sekunder mengenai helminthiasis ini diperoleh dari Balai Veteriner Medan dari tahun 2019-2020 dan dilengkapi dengan data dari Dinas Ketahanan Pangan dan Peternakan Provinsi Sumatra Utara. Total populasi sapi potong di Provinsi Sumatra Utara pada tahun 2019 sebanyak 864.680 ekor dan pada tahun 2020 sebanyak 891.868 ekor yang tersebar di 33 kabupaten/kota. Survailans yang dilakukan oleh Balai Veteriner Medan meliputi 22 kabupaten/kota. Data yang diperoleh disajikan secra deskriptif dan diolah menggunakan software Microsoft Excel® 2007. Hasil penelitian menunjukkan bahwa tingkat kejadian paramphistomosis lebih tinggi daripada fasciolosis, dengan persentase berturut-turut sebesar 48,49% dan 5,48%. Berdasarkan hasil tersebut, dapat disimpulkan bahwa sapi potong di Provinsi Sumatra Utara lebih banyak menderita paramphistomosis daripada fasciolosis. Sementara itu, dari segi pertumbuhan populasi sapi potong di provinsi Sumatra Utara tetap mengalami peningkatan dari tahun 2019-2020., Fasciolosis and paramphistomosis are diseases caused by worm parasites that attack the liver and rumen where the transmission can be through snails. The disease can cause losses both in terms of health and economics. This study aims to analyze the incidence of fasciolosis and paramphistomosis and calculate the population increase in beef cattle in North Sumatra Province. This secondary data on helminthiasis was obtained from the Medan Veterinary Center from 2019-2020 and is complemented by data from the Food Security and Livestock Service Office of North Sumatra Province. The total population of beef cattle in North Sumatra Province in 2019 was 864.680 heads and in 2020 as many as 891.868 heads spread across 33 districts/cities. The surveillance carried out by the Medan Veterinary Center covers 22 districts/cities. The data obtained were presented descriptively and processed using Microsoft Excel® 2007 software. The results showed that the incidence of paramphistomosis was higher than fasciolosis, with the percentages being 48,49% and 5,48%, respectively. Based on these results, it can be concluded that beef cattle in North Sumatra Province suffer more from paramphistomosis than fasciolosis. Meanwhile, in terms of population growth, beef cattle in North Sumatra province continued to increase from 2019-2020.

Judul: Kajian Penyakit Parasit Darah pada Sapi Potong Peternakan Rakyat di Kecamatan Ujungjaya, Kabupaten Sumedang, Jawa Barat
Abstrak: The purpose of this study was to determine the prevalence, risk factor and parasitemia blood parasite based on age and sex category on cattle in Ujungjaya sub-district, Sumedang regency, West Java. Blood samples were collected from 139 cattle in July 2012. Thin blood smears were made on glass slide, fixed in methanol, stained with Giemsa 10% and observed using a microscope with 1000x magnifications. The amount of intraerythrocytic parasite counted for every 500 red blood cells. The potential of risk factor in regard with age, sex, ways to raise, flies and tick control were analyzed with chi-square. The result showed that the highest prevalence was observed in Anaplasma sp. (38.8%), followed by Babesia sp. (33.8%), and Theileria sp. (22.3%). The prevalence of babesiosis and anaplasmosis are influenced by age and ways to raise (p<0.05), while theileriosis had not significantly different. Sex did not affect the level of prevalence. The prevalence of babesiosis is influenced by flies and tick control (p<0.05), while anaplasmosis and theileriosis did not differ significantly. In general, the level of parasitemia increased along with increasing by age. The parasitemia of babesiosis in cow had differently with bull (p<0.05), while anaplasmosis and theileriosis had not significantly different. Percentage parasitemia at various age and sex have the same value that is <1%, which is relatively mild levels of parasitemia.
