Tanaman wori merupakan salah satu tanaman kelompok fabaceace yang tumbuh melimpah di Sangihe dan sangat potensial digunakan sebagai salah satu sumber pakan ikan. Kadar protein daun wori adalah 25,53% sehingga berpotensi menjadi protein nabati bagi ikan. Kendala utama yang ditemui ketika memanfaatkan daun tanaman wori adalah kandungan karbohidrat yang tinggi yaitu 48,51% sehingga dapat mempengaruhi proses pencernaan ikan, penyerapan nutrisi yang berujung pada rendahnya pertumbuhan ikan. Tujuan dari penelitian ini adalah untuk mengetahui pengaruh tepung daun wori femerntasi terhadap laju pertumbuhan spesifik dan sintasan hidup ikan nila. Rancangan percobaan yang digunakan adalah Rancangan Acak Lengkap (RAL). Perlakuan yang dilakukan terdiri dari tiga perlakuan dan tiga kali ulangan yaitu kadar tepung daun wori tanpa fermentasi A (kontrol) 10%, kemudian B tepung daun wori fermentasi (10%), dan C tepung daun wori fermentasi (20%). Laju pertumbuhan spesifik dan efisiensi pakan diuji menggunakan ANOVA sedangkan sintasan hidup akan dianalisis secara deskriptif. Hasil penelitian ini menunjukan bahwa penambahan tepung wori fermenasi dalam pakan dapat meningkatkan nilai laju pertumbuhan spesfik ikan nila dan efisiensi pemanfaatan pakan dengan nilai tertinggi pada perlakuan C yaitu SGR 1,94%/hari. Sementara itu, untuk semua perlakuan nilai sintasan hidup sebesar 100%.   The wori plant is one of the plants of the fabaceace group that grows abundantly in Sangihe and has potential to be used as a source of fish feed. The protein content of wori leaves is 25.53%, so it has the potential to become vegetable protein for fish. The main obstacle encountered when utilizing wori plant leaves is the high carbohydrate content of 48.51% so that it can affect the digestion process of fish, nutrient absorption which lead to low fish growth. The purpose of this study was to determine the effect of wori femerntation leaf meal on the specific growth rate and survival of tilapia. The experimental design used was a completely randomized design (CRD). The treatments consisted of three treatments and three replications, namely the content of fermented wori leaf powder, A (control) 10%, then B fermented wori leaf powder (10%), and C fermented wori leaf powder (20%). Specific growth rate and feed efficiency were tested using ANOVA, while survival rate was analyzed descriptively. The results of this study indicate that the addition of fermented wori powder in the feed can increase the value of the specific growth rate of tilapia and feed utilization efficiency with the highest value in treatment C, namely SGR 1.94% / day. Meanwhile, for all treatments the survival rate was 100%.

This study aimed to evaluate the use of wattle tannin as an adsorbent of toxic metals in broilers fed on diets with different levels of replacement of limestone with golden mussel meal. First, we conducted a trial to evaluate the performance of broiler chicks from 1 to 21 days old when fed on wattle tannin. For this we used 720 male broiler chicks that were one day old, in a completely randomized design with six treatments and six replications. The treatments were composed of basal diets with increasing levels of wattle tannin (0, 250, 500, 750, 1000 and 1250 g tonne-1), where the tannin replaced the inert material of the feed. All of the diets were isonutritive and isocaloric. The results showed that 250 g tonne-1 of tannin was detrimental to weight gain, final weight and feed conversion, and the use of 1000 g tonne-1 of wattle tannin, in addition to these effects, caused a drop in consumption of the ration. There was no effect of treatment on morphometric measurements of villi, crypt or the villus:crypt ratio. Next, we conducted a second test to evaluate the performance of broiler chicks from 1 to 21 days of age when fed with increasing levels of replacement (0, 25, 50, 75, 100%) of limestone with golden mussel and even supplementation or not wattle tannin. Five repetitions were used and the birds were housed in a completely randomized design. In diets with the inclusion of tannin, 250 g tonne-1 of wattle tannin was used, which replaced the inert material in the feed. In this test, 1200 male broiler chicks that were one day old were used. The results showed that the golden mussel contains large quantities of calcium, with low concentrations of toxic metals and microbiological contamination within the allowed range. Performance data show that mussel can be used to replace up to 100% of limestone in feed without affecting the variables, but the use of 250 g tonne-1 of wattle tannin affects the performance of chicks. Bone quality was not changed by the treatments. Phosphorus and calcium in the bones remained stable during treatment and only the gray variation showed interaction effects from the use of mussel and wattle tannin.

Snakehead fish (Channa sp.) was one of Indonesia's native freshwater commodities that has been successfully domesticated by fish cultivators in Indonesia. However, domesticated snakehead fish cultivation still has obstacles, namely the high value of the feed conversion ratio and the low growth rate of local snakehead fish. Overcoming this problem requires a technology that can optimize the feed conversion ratio and growth rate of domestic snakehead fish. One technology that can be applied is the used of probiotic technology. This study aims to test the provision of different probiotics through feed to optimize the feed conversion ratio and growth rate of domestic snakehead fish. This research was conducted using experimental methods. The experimental design used was a completely randomized design with 4 treatments and each treatment was repeated 3 times. The treatments were treatment without probiotics / control (P0), treatment of the probiotic composition of Lactobacillus sp., Bacillus spp. and Nitrosomonas sp. (P1), treatment of the probiotic composition of Lactobacillus casei and Saccharomyces cerevisiae (P2), treatment of the probiotic composition of Lactobacillus sp., Acetobacter, Rhodobacter sp., Yeast (P3). The results showed that giving different probiotic compositions through feed on the parameters of feed conversion ratio and growth rate did not give results that were not significantly different (P> 0.05) when compared to control, but the highest treatment value was found in the probiotic composition of Lactobacillus casei and Saccharomyces cerevisiae.

The experiment was carried out to evaluate the productive performance of European quails (Coturnix coturnix) in the production phase, fed with diets containing different levels of digestible lysine. A total of 175 female quails, aged 65 days, were randomly distributed in a completely randomized design with five treatments and five replicates per treatment. The animals were housed in 25 metal cages, and each cage represented an experimental parcel, with seven birds per parcel. The birds were fed the experimental rations containing 1.177, 1.217, 1.317, 1.417, and 1.517% digestible lysine. The parameters evaluated were: laying rate, mass of eggs produced, feed intake in the period, lysine intake, feed conversion per dozen and per mass. Significant differences were observed for posture rate with quadratic behavior, which indicated higher production for the level of 1.23% of digestible lysine. There was an increasing linear behavior for the feed and lysine intake, and for conversion feed per dozen and by mass, we observed quadratic behaviors. This indicates better feed conversion index when the optimal inclusion level was 1.33% and 1.404% of digestible lysine in the diet, respectively. The requirement of digestible lysine in diets for European quails is 1.404%, which corresponds to a daily intake of 421.20 milligrams of digestible lysine.

This study aimed to evaluate the use of acacia tannin as a toxic metal adsorbent in the diets of broilers fed with the inclusion of golden mussel meal in substitution for calcitic limestone. In the first trial, 648 male 21-day-old animals were divided among six treatments and six replicates, with 18 birds per experimental unit, organized in a completely randomized design (DIC). The treatments were diets with different acacia tannin levels (0, 250, 500, 750, 1000, or 1250 g ton-1). The results indicated that 250 g ton-1 of tannin was not harmful to weight gain, final weight, or feed conversion. Tannin levels caused a decrease in carcass yield and fat deposition and an increase in liver size. For the second trial, 900 male broilers of 21 days of age were used and distributed in a DIC, with different levels of substitution of calcitic limestone by the golden mussel meal (0, 25, 50, 75, or 100 %) and supplementation or not with acacia tannins (250 g ton-1), with 5 replicates and each experimental unit being composed of 18 birds. The performance data show that the use of 250 g ton-1 of tannin is detrimental to bone performance and resistance and golden mussel meal can be used to substitute up to 100 % of the limestone in the diets without affecting the variables studied.

Background: Research on supplementing feed with rice husk activated charcoal was carried out to determine the effect of variations in the concentration of rice husk activated charcoal on the growth and histological features of the Caranx ignobilis intestine. Methods: This study used an experimental method with a completely randomized design consisting of six treatments and four replications, including adding activated charcoal to feed at concentrations of 0%, 1%, 1.5%, 2%, 2.5%, and 3% for 42 days. The measured parameters included daily growth rate (DGR), specific growth rate (SGR), absolute growth rate (AGR), feed conversion ratio (FCR), feed efficiency (FE), survival rate (SR), length of foveola gastrica, width of foveola gastrica, length of intestinal villi, and width of intestinal villi. Data were analyzed statistically using one-way analysis of variance and Duncan’s test. Results: The results showed that supplementing fish feed with rice husk activated charcoal at different concentrations significantly affected the values of DGR, AGR, FCR, FE, SR, length of the foveola gastrica, length of the villous intestine, and width of the villous intestine, but did not significantly affect SGR or foveola gastrica width. Conclusion: The 2% rice husk activated charcoal treatment showed the best results for all parameters.

The objective of this research was to know protein and energy digestibilities of marine yeast, as substitution for soybean meal in the ration of patin (Pangasius sp.) and humpback grouper (Cromileptes altivelis).This experiment used completely randomized design with four treatments in triplicates. The treatments were R1 (100% animal protein); R2 (90% animal protein+10% soybean meal); R3 (90% animal protein+5% soybean meal+5% marine yeast); and R4 (90% animal protein+10% marine yeast). The digestibility of protein in ration of patin was significantly different (P<0.01). Marine yeast in patin ration also improved the growth rate (P<0.05). Substitution soybean meal with marine yeast in ration of patin was not influence the energy digestibility and feed conversion ratio (FCR) (P>0.05). Rations with 5 and 10% of marine yeast improved energy and protein digestibility, growth rate and decreased the FCR. Digestibilities of protein and energy, growth rate and FCR in humpback grouper were significantly different (P<0.01) among treatments. Marine yeast in ration of humpback grouper increased digestibilities of protein and energy. However, substitution of animal protein with soybean meal and marine yeast decreased growth rate and improve FRC in humpback grouper.
