Get PDFPrebiotics which are non-digestible ingredients that benefit the host by stimulating growth and activity of health promoting bacteria. This research aimed to know blood parameters of tilapia with the addition of different dose of prebiotics in feed. Fish were feed four times daily in ad satiation. The feed used was commercially feed with 32 % carbohydrates, 7 % lipids and 30 % proteins. The prebiotic used was extracted from sweet potato so called sukuh variety. The experiment were done with three treatments and three replicates, namely 0% prebiotic, 1% prebiotic and 2% prebiotic. The result showed that application of prebiotic in feed can promote better tilapia blood parameters and immune system compared to control. The treatment with the addition of 1% prebiotic showed best result to improve leucocyte, lymphocytes and the phagocytic index among other treatments.Keyword: blood parameters, immune system, prebiotic, Tilapi
APLIKASI PREBIOTIK UNTUK MENINGKATKAN NILAI KECERNAAN PAKAN IKAN NILA (Oreochromis niloticus)
Get PDFTilapia (Oreochromis niloticus) is one freshwater fish which have high economic value. In the culture of tilapia, feed is the most important external factors. The optimal levels of protein to support the growth of tilapia ranged from 28-40 %, however the digested one is only about 20-25 % and the others were wasted and accumulated in the water. An attempt have been done to improve the feed digestibility value in tilapia by using the prebiotics addition to the feed. The aims of this research was to evaluate the addition of prebiotics to the feed to improve feed digestibility value in tilapia. The parameters measured were the amount of feed intake, the total population of bacteria, protein digestibility, fat digestibility, total digestibility, protein retention, fatty retention, specific growth rate, survival rate and feed efficiency. The results showed that the protein digestibility was 92.25%, fatty digestibility was 96.61% and total digestibility was 86.77%. The best results of feed was found in the addition of 1% prebiotic.Keyword: digestibility, prebiotics, tilapi

PENYEBARAN CACING PARASITIK PADA IKAN KEMBUNG PEREMPUAN (Rastrelliger brachysoma) DI PULAU JAWA
Get PDFHelminth is one of the many parasitic groups found on the body of the fish. The helminth parasitic can inflict harm ecologically, biologically and economically. Monitoring of the distribution of disease in fish is crucial especially when the fish has a pattern of migration from one place to another. Fish sampling was carried out in September – October 2012 from the place of landing of Fishes (TPI), i.e. TPI's Pelabuhan Ratu (West Java province), TPI Karangantu (Banten Province), TPI Bandar Lampungprovince of Bandar Lampung), TPI Muara Angke (DKI Jakarta), and TPI BanyuwangiEast Java province). As many as 160 of 218 R. brachysoma (a prevalence 73.38 %), and number of intencity is 1.378 ± 11.96. The helmint parasitic is a Lechitocladium angustiovum (Digenea: Hemiuridae), Lecitochirium sp. (Digenea: Hemiuridae), Prodistomum orientalis (Digenea: Lepocreadiidae) and Anisakis typica (Nematodes: Anisakidae). Differences in characteristics of R. brachysoma habitat will cause differences in the amount, intensity and prevalence of the helminth parasitic species investment in an area. This is related to the behavior of eating and food availability of R. brachysoma. The distribution of the helminth parasitic in the digestive organs is on intestine (13.72%) and stomach (86.28%), utilizing the existing nutrients as food. In very small amounts, the relationship between the parasite and its host is a mutually beneficial symbiotic relationship but in great numbers, the helminth parasitic infection can lead to secondary infections on the infected organs and can lead to decreased metabolism.Keyword: distribution, helminth parasites, short body mackerel, Jawa Sea, Rastrelliger brachysom
