Judul: Tingkat Prevalensi dan Derajat Infeksi Cacing Saluran Pencernaan pada Sapi Perah di Kecamatan Pangalengan Kabupaten Bandung
Abstrak: The objective of this study was to determine the prevalence and intensity of gastrointestinal helminth infections on the dairy cattle in Kecamatan Pangalengan, Kabupaten Bandung. Fecal samples were collected from 120 cows in 3 Komda and examined with Mc Master and sedimentation filtration modification method to detect the presence of worm eggs and determine the numbers of egg per gram of feces (EPG). Risk factors associated with farm management were obtained by questionnaires through direct interviews with farmers. The results showed that of the 120 examined fecal samples, as many as 34 of fecal samples were positive (28.3%) infected with nematode. There were 30 samples (25%) positive to Strongyle, and 4 samples (3.3%) positive to Trichuris spp. The EPG Strongyle was 106.63±105.65 and EPG Trichuris spp. was 105±95.74 which was catagorized as ligth infection. The highest prevalence of Strongyle infection was seen in the age group <6 months (50%), whereas the highest prevalence Trichuris spp. was seen in the age group 6-12 months (12.5%). Based on location, the highest Strongyle prevalence was found in Komda Mekar Mulya (27.5%), and the highest Trichuris spp. prevalence was found in Komda Padahurip (7.5%).

Judul: Gastrointestinal Helminth Infections in Small Ruminants at PT Jonggol Mitra Amanah, Bogor
Abstrak: Ternak ruminansia kecil seperti kambing dan domba merupakan usaha budidaya ternak yang umum digemari masyarakat Indonesia. Salah satu faktor penting yang perlu diperhatikan dalam memelihara ternak kambing dan domba adalah faktor kesehatan, di antaranya infeksi cacing saluran pencernaan. Penelitian ini bertujuan mengidentifikasi jenis dan mengukur derajat infeksi cacing saluran pencernaan pada kambing dan domba di PT Jonggol Mitra Amanah, Kabupaten Bogor. Pemeriksaan sampel tinja menggunakan metode kualitatif yaitu pengapungan sederhana dan modifikasi filtrasi sedimentasi, serta metode kuantitatif yaitu McMaster. Pemupukan tinja dilakukan untuk mengidentifikasi jenis larva infektif strongylid dan Strongyloides. Jenis cacing saluran pencernaan yang ditemukan pada kambing dan domba di PT Jonggol Mitra Amanah adalah Strongyloides sp., Haemonchus sp., Trichostrongylus sp., Oesophagostomum sp. Selain jenis tersebut, pada kambing ditemukan juga Moniezia sp. Tingginya derajat infeksi dan tingkat prevalensi cacing disebabkan oleh sistem pemeliharaan semiintensif, lingkungan peternakan yang sesuai untuk perkembangan cacing, serta pengulangan pemberian obat anthelmintik yang belum efisien., Small ruminant such as goats and sheep are commonly herbivore livestocks kept by farmer in Indonesia. An important factor to be considered in maintaining goats and sheep is their health, including gastrointestinal helminth infections. This study aims to identify the types and measure the degree of gastrointestinal helminth infections in goats and sheep at PT Jonggol Mitra Amanah, Bogor. Fecal samples were analyzed using a combination of qualitative techniques, specifically simple flotation and modified sedimentation filtration. Additionally, a quantitative method called McMaster was also used in the analysis. Fecal culture was performed to obtain infective strongylid and Strongyloides larvae for further identification. The gastrointestinal helminths found in goats and sheep at PT Jonggol Mitra Amanah were Strongyloides sp., Haemonchus sp., Trichostrongylus sp., and Oesophagostomum sp. In addition, Moniezia sp. was also found in goats. The heavy infection degree and high prevalence of helminthiasis were caused by semiintensive farming system, suitable environment for worms, and inefficient repetition of anthelmintic administration.
