Abstract

This study aims to determine the prevalence and morphological identification of Eimeria spp. from Bali cattle feces on traditional farms in Sumbawa District. A total of 300 samples were identified and 238 samples were positive, resulting in a prevalence of Eimeria spp. of 79.33%. Based on age category, the highest prevalence of Eimeria spp. was found in cattle aged 6 months-2 years (88.76%; 79/89), followed by cattle aged  <6 months (88%; 88/100) and the lowest prevalence in cattle aged >2 years (63.96%; 71/111). Female Bali cattle had the highest prevalence of Eimeria spp. (80.55%; 145/180) than male Bali cattle (77.50%; 93/120). Based on livestock systems, the highest prevalence of Eimeria spp. was found in semi-intensive (89.15%; 74/83), then extensive (80.76%; 105/130) and the lowest in intensive (67.81%; 59/87). Six different Eimeria species were identified: E. bovis (33.19%), E. auburnensis (21.42%), E. zuernii (15.96%), E. alabamensis (12.18%), E. ellipsoidalis (10.50%), and E. canadensis (6.72%). Preventing and controlling coccidiosis infection in cattle can be done with good hygiene management.

Abstract

Tris yolk is a diluent that can be used to maintain and protect spermatozoa during storage so that they can be used in the process of artificial insemination. The length of storage greatly affects the motility and viability of spermatozoa in semen. The purpose of this study was to determine the effect of long storage of egg yolk tris diluent on the motility and viability of simental bovine spermatozoa. This research was carried out at the Banyumulek Artificial Insemination Center Laboratory, West Nusa Tenggara Province, from July to Desember 2024. The study of the effect of long storage of egg yolk tris diluent on the motility and viability of simental bovine spermatozoa used a randomized experimental method complete with four treatments and six repeats. Each treatment, namely P1, P2, P3, and P4, was carried out by mixing 0.075 ml of semen and 0.3 ml of egg yolk tris diluent stored for 24, 48, 72, and 96 hours. The data obtained were processed by variety analysis method (ANOVA) and Duncan's further test. The results showed that P1 treatment with a storage period of 24 hours resulted in the highest average motility and viability values of 63.33 ± 6.055 % for motility and 63.50 ± 6.892 % for spermatozoa viability. P4 treatment with a storage period of 96 hours still showed a good mean value with motility values of 40.83 ± 7.360 % and spermatozoa viability of 53.50 ± 12.112 %. Thus, egg yolk tris is suitable for use as a semen thinner for artificial insemination because it is able to maintain the motility and viability of spermatozoa even for a long time of 96 hours.

Abstract

Fasciolosis merupakan penyakit yang disebabkan oleh parasit Fasciola sp. yang menyerang hewan ruminansia dan sering menyebabkan kerugian dikalangan peternak berupa turunnya tingkat produktivitas ternak bahkan sampai menyebabkan kematian pada ternak. Pengobatan secara rutin dengan anthelmintik yang sama dapat menimbulkan resiko terjadinya resistensi. Daun kelor merupakan jenis hijauan pakan ternak yang selain dapat memenuhi kebutuhan protein dan serat yang tinggi juga dapat berfungsi sebagai obat herbal anthelmintik. Penelitian ini bertujuan untuk mengetahui efek vermisidal ekstrak daunkelor terhadap Fasciola Sp. secara in vitro ditinjau dari lama waktu kematian. Sampel yang digunakan dalam penelitian ini adalah cacing Fasciola yang di ambil dari Rumah Potong Hewan (RPH) Majeluk. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) dengan 5 perlakuan dengan 5 pengulangan, perlakuan pada penelitian ini terdiri dari ekstrak daun kelor konsentrasi 2,5%, 3,5% dan 4,5%. Albendazole sebagai kontrol positif dengan serta kontrol negatif menggunakan aquades. Data yang diperoleh dianalisis dengan sidik ragam analysis of variance (ANOVA), diuji lanjut menggunakan uji duncan. Hasil penelitian ini menunjukkan perlakuan ekstrak daun kelor dengan konsentrasi 2,5%, 3,5%, 4,5% memiliki pengaruh yang berbeda nyata (P>0,05) dalam mempercepat waktu kematian Fasciola sp. dibandingkan kontrol negatif (aquades), namun masih lebih rendah dibanding perlakuan Albendazole. Pemberian Albendazole menyebabkan kematian cacing lebih cepat dari pada ekstrak daun Kelor.

Abstract

Ikan nila (Oreochromic niloticus) merupakan salah satu ikan air tawar dengan nilai ekonomis penting di Indonesia karena cara budidayanya yang relatif mudah, sebagai sumber protein hewani utama selain daging, telur, dan susu. Serangan parasit membuat ikan kehilangan nafsu makan, kemudian perlahan-lahan lemas dan berujung kematian. Penelitian ini bertujuan untuk mendeteksi ektoparasit pada ikan nila di Desa Perian, Kecamatan Montong Gading, Kabupaten Lombok Timur. Penelitian ini dilakukan pada bulan Oktober- November 2024 dengan menggunakan 78 ekor sampel ikan dari 13 kolam budidaya dengan metode natif scraping dan biopsi. Hasil penelitian dari 78 sampel menunjukkan bahwa terdaat 25 sampel postif yang terinfeksi Dactylogyrus sp. Prevalensi parasit Dactylogyrus sp. yang menyerang ikan nila (Oreochromis niloticus) mencapai 32,05%. Protozoa Trichodina sp. yang menyerang ikan nila (Oreochromis niloticus) mencapai 38%.
