ABSTRACTThe study proposed to discover the optimum protein content and energy-protein ratio in practical diet for snakehead, Channa striata. The experiment applied complete randomized design, consisted of six treatments with four replications on each treatment. The treatments were: A (32.5%; 11.82 kcal GE/g), B (32.5%; 13.32 kcal GE/g), C (37.17%; 10.64 kcal GE/g), D (37.33%; 12.07 kcal GE/g), E (43.08%; 10.02 kcal GE/g), and F (42.88%; 10.66 kcal GE/g). Snakehead with average weight of 6.21 ± 0.03 g were reared for 8 weeks. The treatments showed significant results. Increased protein dietary level had increased the growth rate and treatment with high energy-protein ratio at the same protein dietary level provided better growth performance. However, increased energy-protein ratio at E and F treatments caused a decline in growth performance. The improvement of energy-protein dietary ratio had positive correlation with the level of lipid and protein content in fish body. Similar finding was found in liver and muscle glycogen. The results also showed that the increament of energy-protein dietary ratio was significantly and positively correlated with cholesterol, triglyceride, HDL, glucose, and albumin, yet it had no significant effect on LDL. It can be concluded that excellent growth performance was achieved by protein dietary level of 37.33% and energy-protein ratio of 12.07 kcal GE/g.Keywords: energy-protein ratio, growth, snakehead ABSTRAKPenelitian ini bertujuan untuk memperoleh kadar protein dan rasio energi-protein pakan buatan yang optimum bagi performa pertumbuhan ikan gabus. Penelitian ini mengaplikasikan rancangan acak lengkap dengan 6 perlakuan, yaitu: A (32,78%;11,82  kkal GE/g), B (32,56%;13,32 kkal GE/g), C (37,17%:10,64 kkal GE/g), D (37,33%:12,07 kkal GE/g), E (43,08%:10,02 kkal GE/g), dan F (42,88%:10,66 kkal GE/g) dan masing-masing terdiri 4 ulangan. Bobot rata-rata ikan gabus yang digunakan dalam penelitian ini yaitu 6,21 ± 0,03 g dan dipelihara selama 8 minggu. Hasil penelitian menunjukkan bahwa peningkatan kadar protein pakan meningkatkan laju pertumbuhan, dan perlakuan dengan rasio energi-protein tinggi pada level protein pakan yang sama memberikan kinerja pertumbuhan yang lebih baik. Namun demikian, pada perlakuan E dan F, peningkatan rasio energi-protein menyebabkan penurunan kinerja pertumbuhan. Peningkatan rasio energi-protein pakan berkorelasi positif terhadap kadar lemak dan protein tubuh ikan. Hal yang sama juga terjadi pada glikogen hati dan otot. Hasil penelitian juga menunjukkan bahwa peningkatan rasio energi-protein pakan berpengaruh nyata (P<0,05) dan  berkorelasi positif terhadap kolesterol, trigliserida, HDL, dan albumin, tetapi tidak berpengaruh nyata terhadap LDL  (P>0.05). Kesimpulan yang didapat adalah kinerja pertumbuhan optimal dihasilkan oleh kadar protein pakan 37,33% dan rasio energi protein pakan 12,07 kkal GE/g.Kata kunci: albumin, energi, ikan gabus, pertumbuhan, protein

The study investigated the effects of re-alimenting dietary protein or energy on growth, carcass characteristics and meat eating quality parameters of sheep. Twenty-seven intact rams (~9 months; 11.3 ± 0.5 kg) were randomly divided into three groups. Each group was fed a maintenance diet (MT) containing, on dry matter (DM) basis, 105 g/kg crude protein (CP) and 8.4 MJ/kg DM metabolizable energy (ME) for 30 days. Thereafter, they were continually fed the same MT or re-alimented with a high protein diet (HP) containing 169 g/kg DM CP and 9.3 MJ/kg ME or a high energy diet (HE) containing 123 g/kg DM CP and 10.6 MJ/kg ME for an additional 30 days to determine the effects of re-alimentation of protein or energy on their growth performance and carcass characteristics. During the initial 30-day period, DM intake (DMI) and growth performance were similar among the three groups. However, upon re-alimentation, average daily gain (ADG) and feed efficiency of sheep re-alimented with HP were greater than those maintained continually on MT or re-alimented with HE. Sheep on HP had higher feed efficiency, ADG and heavier carcasses than those fed MT or re-alimented with HE during the whole 60-day period. Growth of most viscera was less responsive to the restriction-re-alimentation feeding regimen except for the weights of the lungs, heart and intestines. Meat from sheep re-alimented with HE had a more intense ‘sheepy’ flavour than those fed MT or re-alimented with HP, but juiciness and tenderness were not affected. The higher ADG of sheep re-alimented with protein may be related more to enhanced efficiency of feed utilization than to higher DMI.Keywords: average daily gain, feed restriction, nutrient utilization efficiency, visceral organs

<p>ABSTRACT</p><p><br />This 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&lt;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 grouper</p><p><br />Keywords: digestibility, growth performance, DDGS, hominy, humpback grouper, Cromileptes altivelis</p><p><br />ABSTRAK</p><p><br />Penelitian 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&lt;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%).<br /><br />Kata kunci: pertumbuhan, ketercernaan, DDGS, homini, ikan kerapu bebek, Cromileptes altivelis</p>

Currently, the use of unconventional food sources in the inclusion of fish diets is cause of great interest. The growth performance of African catfish (Clarias gariepinus) was evaluated, with the inclusion of duckweed meal (Lemna perpusilla) in four levels (0, 6, 12 and 18 %) in the diet. African catfish with an average weight of 1.27 ± 0.03 g, were distributed in a completely randomized design, with 16 experimental cages (four replicates/treatment). The fingerlings were fed for 48 days of experimentation. An analysis of variance and a Duncan´s test were performed. No significant differences were found (p< 0.05) for the first two levels evaluated, but with the rest there were differences, as the percentage of inclusion of the duckweed meal in the ration increased. Final weight was decreasing, as well as absolute growth rate, increase in daily weight, feed conversion ratio and food efficiency. Survival throughout the experiment was between 72 y 65 % in all treatments. The inclusion of duckweed meal in the diet did not affect the parameters of water quality. It was concluded that the L. perpusillase meal can be included up to 12 % in diets for African catfish fingerlings, without affecting the growth performance.

High energy diet is related to high feed cost. Thus, it is essential to reduce energy diet but still support the good performance of birds. The utilization of low cost- feed ingredients combined with enzymes are the alternative way to do. The objective of this study was to investigate the effects of multy-enzyme supplementation on growth performance of broilers fed low energy basal diets containing rice bran. Experiment 1. The apparent metabolizable energy (AME) assay of yellow corn and rice bran. A total of 48 broilers were randomly distributed to 12 cages (4 birds/cage). A maize-soybean meal basal diet (mash form) was formulated and two assay diets were then developed by substituting rice bran (raw 250 g kg-1, w/w) and maize (500 g kg-1, w/w) of the basal diet. Total excreta collection method was used. The results showed that the AME value of rice bran was significantly lower (2032 kcal/kg DM) and 3112 Kcal/kg DM. Experiment II. The experiment was designed using a completely randomized design with four treatments and six replications. A total of 160 DOC (unsex) were randomly distributed to 16 pens (10 birds/pen). The experimental diets were iso-nitrogenous and iso-energetics. The results show that dietary treatments significantly affected (P0.05) FCR and mortality of broilers. Broilers fed P2, P3 and P4 diets had higher (P0.05). In conclusion, 1) the supplementation of enzymes in low energy diets containing rice bran improved BWG and FI but not FCR and mortality. 2) Birds fed rice bran-containing-diets supplemented with enzymes produced similar growth performance.

ABSTRACTForty-five piglets were used to study the effects of feeding diets containing 153, 239 or 321 g crude protein per kg dry matter between 1·8 and 6·5 kg live weight, and low and high protein diets subsequent to 6·5 kg live weight on growth performance, body composition and the cellularity of skeletal muscle to 45 kg live weight.Reducing dietary crude protein between 1·8 and 6·5 kg live weight depressed growth performance and at 6·5 kg live weight increased body fat content but reduced body protein, body water and the weight and DNA content of the adductor muscle. The effects of dietary protein content before 6·5 kg live weight on body composition at the latter weight were still evident in pigs killed at 11·5 kg live weight whilst the differences in muscle DNA persisted to 45 kg live weight.On the lower protein treatment subsequent to 6·5 kg live weight there was a tendency for pigs given the lowest protein diet before 6-5 kg live weight to exhibit better growth performance and deposit protein at a faster rate than those given the higher protein diets. However, these responses were reversed on the higher protein treatment subsequent to 6·5 kg live weight.The effects of dietary protein content subsequent to 6·5 kg live weight on growth performance, body composition and the cellularity of muscle tissue were qualitatively the same as those for the live-weight phase 1·8 to 6·5 kg.
