Abstract

This experiment was conducted to evaluate the effect of phytase levels in the diet on the digestibility and growth performance of white shrimp Litopenaeus vanname. White shrimp were used in the trial with initial body weight of 3.8±0.01 g were reared in  aquarium (60×40×50 cm3) and filled with 60L treated sea water at a density of ten individu. Experimental diet were formulated in isonitrogeneous (36% protein) and isocaloric (3960 kcal/kg) to contain four levels of phytase: 0 iu/kg (diet A), 500 iu/kg (diet B), 750 iu/kg (diet C), and 1000 iu/kg(diet D). All diets were supplied with 0.5% of Cr2O3 as an indicator for digestibility measurement shrimp fed three times daily at satiation levelfor how many days of rearing. A factorial completely randomized experimental design was selected consisted of four treatments and triplicates. The result showed that the phytase addition improved the digestibility of protein, calcium, and phosphor as well as improve growth performance of white shrimp. Based on evaluation of those parameters, it is concluded that phytase level of500 IU support the best growth performance ofjuvenile white shrimp.

Abstract

This experiment was conducted to study the activity, protein retention, daily growth rate, and production of Dendronereis pinnaticirris cultured in different soil substrates. Forty tested worms with average body weight of 150 mg were adapted in laboratory for 30 days. Thereafter, worms were cultured for 30 days in the 13.6 L aquaria and equipped with aeration system. A triplicate experiment was conducted using 10 cm depth of sterilized soil substrate with particle diameter of either 63‒250 μm, 250‒500 μm, or without substrate. The results showed that (1) D. pinnaticirris always swims actively when cultured in the medium without substrate, thereby resulting into the mass mortality (96.7%); (2) the substrate with particle diameter of 63‒250 μm generated significantly higher daily growth rate, survival rate, and production of D. pinnaticirris, but protein retention and feed efficiency were insignificance with those cultured in the substrate of 250–500 μm.Keywords: substrate, protein retention, production, Dendronereis pinnaticirris

Abstract

ABSTRACT Two experiments were conducted to evaluate the effect of sheep rumen liquor enzyme addition on the reduction of cocoa-pod husk meal (CPHM) fiber content, and the digestibility of hydrolyzed CPHM for tilapia Oreochromis niloticus. In the first trial, sheep rumen liquor enzyme was added with various concentration, i.e. 0, 50, 100 and 150 mL/kg CPHM with three different incubation periods, namely 0, 12, and 24 hours. In the second trial, digestibility was determined by the addition of Cr2O3 as the indicator in both reference and experimental diets, i.e. feed with hydrolyzed CPHM and unhydrolyzed CPHM. Tilapia with an average body weight of 3.86±0.44 g were stocked at a density of 15 fish/aquarium and were maintained for 15 days. In the first trial, CPHM hydrolyzed with 150 mL/kg and incubated for 12 and 24 hour showed the lowest crude fiber content (21.38% and 21.67%). Apparent digestibility coefficient of hydrolyzed CPHM was 33.95%, which was higher than unhydrolyzed CPHM (10.97%). As conclusions sheep rumen liquor enzyme addition was effective to decrease crude fiber content of CPHM and improve the apparent digestibility coefficient of CPHM for tilapia diet. Keywords: sheep rumen liquor enzyme, cocoa-pod husk meal, digestibility, tilapia  ABSTRAK Dua tahap penelitian dilakukan untuk mengevaluasi penambahan enzim cairan rumen domba dalam menurunkan kandungan serat kasar kulit buah kakao (KBK) dan mengevaluasi ketercernaan KBK yang telah dihidrolisis dengan enzim cairan rumen domba dalam pakan ikan nila Oreochromis niloticus. Pada penelitian tahap satu, enzim cairan rumen domba ditambahkan dengan konsentrasi yang berbeda yaitu 0, 50, 100, dan 150 mL/kg KBK dengan lama inkubasi yang berbeda yaitu 0, 12, dan 24 jam. Pada penelitian tahap dua, nilai ketercernaan ditentukan dengan menggunakan indikator Cr2O3 yang ditambahkan ke dalam pakan acuan dan pakan perlakuan, yaitu pakan dengan penambahan KBK yang telah dihidrolisis dengan dosis terbaik pada penelitian tahap satu (KBKe) dan kulit buah kakao tanpa hidrolisis (KBK). Ikan nila yang digunakan mempunyai bobot rata-rata 3,86±0,44 g ditebar dengan kepadatan 15 ekor/akuarium dan dipelihara selama 15 hari. Hasil penelitian tahap satu menunjukkan hidrolisis KBK dengan menggunakan cairan rumen 150 mL/kg dan lama waktu inkubasi 12 jam dan 24 jam mempunyai nilai serat kasar KBK terendah yaitu sebesar 21,38% dan 21,67%. Pada uji ketercernaan terlihat bahwa nilai ketercernaan bahan KBKe lebih tinggi (33,95%) dibandingkan dengan KBK (10,97%). Dengan demikian dapat disimpulkan bahwa penambahan enzim cairan rumen domba dapat menurunkan kandungan serat kasar kulit buah kakao dan meningkatkan ketercernaan kulit buah kakao pada pakan ikan nila. Kata kunci: enzim cairan rumen domba, kulit buah kakao, ketercernaan, ikan nila

Abstract

ABSTRACTThis experiment was conducted to evaluate the use of by product of corn ethanol industry, DDGS (distiller dried grain with soluble) and hominy as feed raw material on digestibility and the growth performance of humpback grouper Cromileptes altivelis juvenile. Three experimental diets containing isoprotein (48%) but different in DDGS contain were used. Diet A containing 0% of DDGS and hominy while diet B and C containing 10.13% (6.13% of DDGS and 4% of hominy) and 19.05% (15.05% of DDGS and 4% of hominy). Reduce of fish meal level in the diet was happen as a consequence of balancing amino acid. For digestibility experiment and Cr2O3 at level of 0.05% was used as a tracer. The feces were daily collected 30‒60 minutes after feeding for 14 days. Dry matter and protein were used as digestibility parameters. Completely randomized design with three treatments and two replicates was used in this experiment. Humpback grouper with an average weight of 11‒14 g were reared at floating net cages (FNG) of 3×2×1.5 m3. The stocking density for each cage was 167 fish/FNG and reared for six months. For digestibility measurement 30 fish were held in cylindrical fiber tank filled with 800 L of sea water. Fish were fed three times daily at satiation level. For maintaining net in a clean condition net was changed in every ten days. Feed consumption, digestibility of protein and total, growth performance indicator i,e specific growth rate, feed efficiency protein and lipid retention were used as evaluating parameters. The results showed that the fish fed with diet containing DDGS (6.13%) dan hominy (4%), at the level of 10.13% (diet B), shows similar growth performance indicators with the fish fed diet A (0% of DDGS and hominy) and the growth performance indicator was higher when being compared to those fish fed diet C (containing 19.05% of DDGS (15.05%) and hominy (4%)) (p<0.05). More over the inclusion of DDGS and hominy at the level of 10,13% give no negatif impact to feed palatability (shown by total feed consumption value) and digestibility of protein. The increasing level of DDGS and hominy more than 10% reduced palatability and protein digestibility. Based on this research, DDGS and hominy can be used up to 10% in the feed formulation of humpback grouperKeywords: digestibility, growth performance, DDGS, hominy, humpback grouper, Cromileptes altivelisABSTRAKPenelitian ini dilakukan untuk mengevaluasi pemanfaatan limbah jagung dari industri etanol dalam bentuk distillate dried grain with soluble (DDGS) dan homini sebagai bahan baku pakan terhadap kinerja pertumbuhan ikan kerapu bebek Cromiliptes altivelis. Ikan yang digunakan dalam penelitian ini adalah juvenil ikan kerapu bebek berukuran 11‒14 g. Ikan dipelihara dalam karamba jaring apung yang berukuran 3×1,5×2 m3 dengan kepadatan 167 ekor/jaring. Ikan diberi pakan sampai kenyang sebanyak dua kali sehari. Untuk menjaga agar jaring tetap bersih maka dilakukan pergantian jaring setiap satu sampai dua minggu sekali. Ikan dipelihara selama lima bulan dan setiap bulan dilakukan sampling. Tiga macam pakan digunakan dalam penelitian ini dengan kadar protein 47% dan rasio energi protein 10 kkal/g protein. Pakan A adalah pakan yang tidak mengandung DDGS dan homini, pakan B mengandung DDGS 6,13% dan 4% (total 10,13%), dan pakan C mengandung DDGS 15,05% dan Homini 4% (total 19,5%). Untuk mengevaluasi ketercernaan nutrien maka kromium oksida (Cr2O3) digunakan sebagai penelusur. Penelitian ketercernaan dilakukan di laboratorium dengan menggunakan fiber dengan volume 800 L. Rancangan acak lengkap dengan tiga perlakuan dan dua ulangan digunakan dalam penelitian ini. Hasil penelitian menunjukkan bahwa nilai ketercernaan nutrien tidak berbeda sampai total kadar DDGS dan homini 10,13% (pakan B) dan peningkatan DDGS serta homini sampai 19,05% (pakan C) menurunkan nilai ketercernaan. Ikan yang diberi pakan dengan DDGS sebesar 10,13% (pakan B) memiliki nilai efisiensi pakan, sintasan, laju pertumbuhan spesifik, konsumsi pakan dan retensi protein yang sama dengan pakan tanpa DDGS (pakan A), akan tetapi nilai-nilai tersebut lebih tinggi jika dibandingkan dengan ikan yang diberi pakan B (p<0,05). Retensi lemak ikan yang diberi pakan B memiliki nilai yang lebih tinggi jika dibandingkan dengan ikan yang diberi pakan A dan C. Dari penelitian ini dapat disimpulkan bahwa DDGS dan homini dapat digunakan sebagai bahan baku pakan ikan kerapu bebek sampai level 10,13% (DDGS 6,13% dan homini 4%).Kata kunci: pertumbuhan, ketercernaan, DDGS, homini, ikan kerapu bebek, Cromileptes altivelis

Abstract

ABSTRACTThe objective of the present experiment was to study the most optimum taurine enrichment concentration of rotifers in improving Pacific white shrimp larva Litopenaeus vannamei survival and development. White shrimp larvae at sixth naupliar stage were reared in 12 units of 500 L fibre glass tanks with a stocking density of 125 ind/L. Starting from zoea two stage (Z-2), the larva was provided with rotifers with different taurine enrichment concentration according to the treatments, i.e. 0 mg/L enrichment medium (A), 25 mg/L (B), 50 mg/L(C), and 100 mg/L (D). The results show that different taurine concentration in the enrichment media increased taurine level in rotifers. Furthermore, the administration of taurine enriched rotifers up to 50 mg/L significantly improved larval survival and may accelerate larval development. The experimental results also concluded that a concentration of 50 mg/L is the most optimum taurine enrichment concentration of rotifers for the improvement of white shrimp larval survival and developmental stage.Keywords: taurine, rotifer, white shrimp, enrichmentABSTRAKPenelitian ini bertujuan untuk mengkaji konsentrasi optimum taurin melalui pengayaan pada rotifera terhadap tingkat kelangsungan hidup dan perkembangan stadia larva udang vaname Litopenaeus vannamei. Larva udang vaname stadia naupli-6 dipelihara dalam 12 tangki fiberglass volume 500 L dengan kepadatan 125 ind/L. Dimulai sejak stadia zoea 2 (Z-2) larva diberi rotifera yang diperkaya dengan taurin dengan konsentrasi yang berbeda sesuai dengan perlakuan, yaitu 0 mg/L media pengkaya (A), 25 mg/L (B), 50mg/L (C), dan 100mg/L (D). Hasil penelitian menunjukkan pengayaan taurin pada konsentrasi yang berbeda menyebabkan peningkatan kandungan taurin rotifera. Sementara pemberian rotifera yang diperkaya taurin hingga 50 mg/L meningkatkan kelangsungan hidup dan mempercepat perkembangan stadia larva udang. Berdasarkan hasil penelitian ini dapat disimpulkan bahwa pemberian rotifera yang diperkaya taurin dengan konsentrasi 50 mg/L menghasilkan tingkat kelangsungan hidup tertinggi (53,5%) dan perkembangan larva yang tercepat (p<0,05) dibandingkan perlakuan lainnya.Kata kunci: taurin, rotifera, udang vanname, pengayaan

Abstract

ABSTRACT Sludge worm (Tubifex sp.) as natural feed on catfish (Pangasionodon sp.) larvae rearing is available in limited amount especially during rainy season. It becomes a constraint factor for larvae rearing sector. This research was conducted to evaluate the appropriate initial age of catfish larvae to get artificial feed as sludge worm replacement. Evaluation was conducted on the growth and survival of catfish larvae in 14 days of culture. There were four treatments of feeding in triplicates i.e. larvae were given natural feed without artificial feed, given artificial feed started from d3, d6, and d9) with three replications. The results showed that larvae fed on artificial feed on d3 had the lowest growth compared to the other treatments, whereas the survival was not significantly different (P>0.05) among the treatments. As a conclusion, artificial feed could be used to replace natural feed for catfish larvae started at the age of nine days. Keywords: sludge worm, catfish larvae, artificial feed  ABSTRAK Cacing sutra (Tubifex sp.) tersedia dalam jumlah terbatas terutama pada musim penghujan sebagai pakan alami dalam usaha pembenihan ikan patin (Pangasionodon sp.).

Abstract

ABSTRACT This research was conducted as a preliminary study on utilization of RBO for Nile tilapia (Oreochromis sp.) diet by also evaluating its effect on growth the performance. This research used SULTANA strain at average initial body weights of 8.33±0.07 g/ind. Experimental design was set in completely randomized design. Each treatment was done in triplicates. The treatments were various additions of RBO to replace corn oil in the diet, which were 0%, 25%, 50%, 75%, and 100%. Feeding rate, feed efficiency, protein retention, fat retention, specific growth rate, glucose, cholesterol, triglycerides, HDL (high-density lipoprotein), and hematology were used as evaluating parameters. The results showed that the growth performance, blood chemistry and hematology of fish decreased as the increasing of RBO level in the diet. These are caused by feed intake decreased significantly, which were 583.5 g to 145.6 g of treatments 0% to 100% RBO. Blood glucose, haemoglobin and specific growth of fish in the treatment of 0–100% RBO were 48.7–22.2 mg/dL, 7.6–5.4%, and 3.5–0.8%, respectively. The lowest survival was observed in fish fed 100% RBO (66.7%). Fish growth performance of 0% RBO was the best, so RBO could not be utilized yet as a source of fatty acid or corn oil replacement in tilapia diet. Keywords: free radical, HCN, Oreochromis sp., rubber seed oil  ABSTRAK Penelitian ini dilakukan sebagai studi awal pemanfaatan minyak biji karet (MBK) untuk pakan ikan nila dan mengevaluasi pengaruhnya terhadap pertumbuhan ikan nila. Ikan uji yang digunakan adalah ikan nila strain SULTANA dengan bobot awal rata-rata 8,33±0,07 g/ind. Penelitian didesain dalam rancangan acak lengkap (RAL) dengan lima perlakuan dan tiga ulangan. Perlakuan yang diuji berbagai sumbangan MBK untuk mengganti minyak jagung dalam pakan, yaitu 0%, 25%, 50%, 75%, dan 100%. Selama pemeliharaan, beberapa parameter yang diukur adalah jumlah konsumsi pakan, efisiensi pakan, retensi protein, retensi lemak, laju pertumbuhan spesifik, glukosa, kolesterol, trigliserida, high-density lipoprotein (HDL), dan gambaran darah. Hasil penelitian ini menunjukkan bahwa kinerja pertumbuhan, kimia darah dan gambaran darah ikan semakin menurun seiring dengan penambahan MBK dalam pakan. Hal ini disebabkan semakin menurunnya jumlah konsumsi pakan secara signifikan, yaitu 583,5 g menjadi 145,7 g dari perlakuan 0% ke 100% MBK. Glukosa darah, hemoglobin dan laju pertumbuhan spesifik ikan pada perlakuan 0–100% MBK masing-masing adalah 48,7–22,2 mg/dL, 7,6–5,4% dan 3,5–0,8%. Sintasan ikan terendah terjadi pada perlakuan 100% MBK, yaitu 66,7%. Kinerja pertumbuhan pada perlakuan 0% MBK adalah yang paling baik sehingga MBK belum dapat dimanfaatkan sebagai sumber lemak menggantikan minyak jagung pada pakan ikan nila. Kata kunci: radikal bebas, HCN, Oreochromis sp., minyak biji karet

Abstract

ABSTRACT This research was conducted to evaluate the effect of different combination of feeding frequency of Tubifex (C) and artificial diet (P) on survival and growth rate of larval yellow tail catfish Pangasianodon hypophthalmus. Newly hatched larvae (d0) with total length of 0.44±0.04 cm were cultured for 14 days in 30×20×20 cm3 aquarium. Water volume in each aquarium was 9 L. At d5, larvae were fed on five different feeding frequencies either 6C+0PB, 5C+2PB, 3C+3PB, 2C+5PB, dan 0C+6PB. Feeding method used in this research was ad libitum. Results showed that survival and total length of d14 old larvae fed on 0C+6PB was lower than the groups fed on either 6C+0PB or three combinations of C+PB. Lipase activity tend to be increase in line with the increasing amount of artificial feed. On the other hand, larvae fed on 6C+0PB and 0C+6PB had the lowest protease activity. Therefore, larval catfish can be fed by combination of Tubifex and artificial feed. Keywords: artificial diet, lipase activity, protease activity, sludge worm, Pangasianodon hypophthalmus  ABSTRAK Penelitian ini mengevaluasi pengaruh perbedaan frekuensi pemberian pakan harian cacing sutra (C) dan pakan buatan (PB) terhadap sintasan dan pertumbuhan larva ikan patin Pangasianodon hypophthalmus. Larva ikan patin yang baru menetas berukuran 0,44±0,04 cm dipelihara dalam akuarium kaca berukuran 30×20×20 cm3 yang diisi air setinggi 15 cm selama 14 hari. Mulai dh5, larva diberi lima perlakuan frekuensi pemberian pakan, yaitu 6C+0PB, 5C+2PB, 3C+3PB, 2C+5PB, dan 0C+6PB. Pemberian pakan dilakukan secara ad libitum. Hasil penelitian menunjukkan bahwa larva yang diberi 6C+0PB dan kombinasi C+PB memiliki tingkat kelangsungan hidup dan panjang akhir yang tidak berbeda nyata. Namun larva yang diberi 0C+6PB, menghasilkan tingkat kelangsungan hidup dan panjang akhirnya terendah. Semakin banyak porsi sering frekuensi pemberian PB yang diberikan menunjukkan tren aktivitas lipase yang cenderung meningkat. Tetapi pada aktivitas protease pada pemberian 6C+0PB dan 0C+6PB lebih rendah dari ketiga perlakuan kombinasi C+PB. Dengan demikian, larva ikan patin dapat dibudidaya dengan menggunakan kombinasi cacing sutra dan pakan buatan. Kata kunci: pakan buatan, aktivitas lipase, aktivitas protease, cacing sutra, Pangasianodon hypophthalmus
