Shrimp culture in the floating cage is expected to reduce the utilization of land and its possible negative impact to the environment. The advantages of shrimp farming in the sea include the high dissolved oxygen concentration and the better meat quality. This research aimed to enhance the production performance of shrimp through the utilization of periphyton as a natural feed for shrimp. A completely randomized design with 3 treatments (in triplicates) were applied in this experiment, i.e floating cage without perishel (control), floating cage with PE perishel and PA perishel. Shrimp with body weight of 2.5 ± 0.2 g were stocked at the initial density of 2,000 shrimp in each cage, and maintained for 90 days. No significant difference was observed in the survival amongst treatments. The lowest feed conversion ratio (1.74) and coefficient of variance (3.21) were showed in treatment PA. The highest attachment and abundances of periphyton were found in treatment PA. It was concluded that the addition of perishel inside the floating cage may contribute as natural feed source for the shrimp and thus increase the production performance of shrimp. Keywords: floating cage, Litopenaeus vannamei, periphyton, perisel, shelter ABSTRAK Budidaya udang di KJA diharapkan dapat menekan isu pemanfaatan daratan sebagai tambak yang berdampak pada permasalahan lingkungan. Keunggulan laut untuk budidaya udang, antara lain adalah kadar oksigen terlarut relatif tinggi sehingga tidak perlu kincir, dan mutu daging udang yang dihasilkan relatif lebih baik.

Ninety head day old chick (DOC) of local village chicken was used in this experiment to evaluate the effect of agricultural by product-based feed supplemented with herbal probiotics (HP) and mud clams extract (MC) on production performance of local village chicken. A completely randomized design was used with 5 treatments and 4 replications. The treatments consisted of control (R0), 0.75%HP+1.5%MC (R1), 1.5%HP+3%MC (R2), 2.25%HP+4.5%MC (R3), and 3.0%HP+6.0%MC (R4). All chicken was kept in a group of five flocks equipped with feeding and water supply apparatus. The results showed that local village chicken got R2 treatment gave a significantly higher response in feed consumption (32.5gd-1) compared to R0 (23.1gd-1), R1 (23.9gd-1), R3 (24.0gd-1), and R4 (21.3gd-1). The daily gain of local village chicken was also significantly higher in R2 treatment (7.4g-1) compared to R0 (4.6gd-1), R1 (4.9gd-1), R3 (4.6gd-1), and R4 treatment (4.1gd-1). However, feed conversion resulted from those treatments did not show a significant difference. The lower feed conversion gain in this experiment has existed in R2 treatment (4.0) followed by treatment R1 (4.9), R0 (5.0), R4 (5.2), and treatment R3 (5.4). Therefore, it was concluded that the treatments had a significant effect on feed consumption and daily gain but had no effect on feed conversion of local village chicken. The inclusion level of 1.5% herbal probiotics and 3% mud clams extract gave better effect on both feed consumption and daily gain of local village chicken.

The objective of this work was to evaluate the performance of Pacific marine shrimp (Litopenaeus vannamei) and tilapia (Oreochromis niloticus), in a polyculture in tanks subjected to different stocking densities and feeding strategies, in comparison with monoculture. Two experiments were performed, at the same time, in a completely randomized design with three treatments and four replicates each. Treatments for experiment I were: monoculture with 10 shrimp per m² (10S:0T); polyculture with 10 shrimp and 0.5 tilapia per m² (10S:0.5T); and polyculture with 10 shrimp and 1 tilapia per m² (10S:1T). Shrimp was the main crop, and feed was provided based on shrimp biomass. Treatments for experiment II were: monoculture with 2 tilapia per m² (2T:0S); polyculture with 2 tilapia and 2.5 shrimp per m² (2T:2.5S); and polyculture with 2 tilapia and 5 shrimp per m² (2T:5S). Tilapia was the main crop, and feed was provided based on fish requirements. In the experiment I, tilapia introduction to shrimp culture resulted in lower shrimp growth and poor feed conversion rate. In experiment II, shrimp introduction to tilapia culture did not interfere with fish performance. Polyculture is more efficient with the combination of 2 tilapia and 2.5 or 5 shrimp per m² and feed based on fish requirements.

This experimental study aims to evaluate the use of Indigofera leaves that have undergone cocktail enzyme treatment in male Mojosari duck feed. The research treatment was using Indigofera leaves due to enzyme cocktail treatment on male Mojosari duck feed with four levels: 0, 5, 10 and 15% of total feed, with six replications (@ five ducks) using 120 ducks in a completely randomized design. The variables measured and observed in this study were the production performance of male ducks, which included feed consumption, body weight growth, feed conversion. The research results were processed by analysis of variance (ANCOVA) because the coefficient of variation in initial body weight was 17.7%. The results showed that the addition of Indigofera leaf meal to the feed of male Mojosari ducks tended to reduce feed consumption (P<0.01) and body weight gain (P<0.05) but did not increase the FCR value (P>0.05). Indigofera flour needs to be processed first with a cocktail enzyme treatment to improve its nutritional quality so that it can be used as feed for ducks in larger quantities. Male Mojosari ducks that are kept need to be harvested at more than seven weeks to get a higher harvest weight.

The aim of the study was to determine the level of use of fermented snail meat protein hydrolyzate (FSMPH) as a reduction of fish meal (FM) in the ration, and its effect on the production performance of “super” native chicken (SNC). Research materials were SNC unsexing and FSMPH. The study used an experimental method with a completely randomized design with 5 treatments and 4 replications. The research ration treatments were: P0 = FM 8% without FSMPH (Control), P1= TI 6%+FSMPH 5 ml/kg ration, P2= TI 4%+FSMPH 10 ml/kg ration, P3= TI 2%+FSMPH 15 ml/kg ration, P4= TI 0%+FSMPH 20 ml/kg ration. The results showed that the a reduction of FM with FSMPH on SNC ration consumption at each level had no significant effect (P>0.05) on control feed, BW, BWG, and FCR in P1, P2, and P3 treatments on control feed, but showed a significant difference (P<0.05) in lower BW, BWG, and higher FCR in P4 treatment of SNC fed with 8% (control). The conclusion was that FSMPH can be used as a reduction  for FM up to 75% of the use of FM in the ration as much as 8%.

The objective was to determine the digestible tryptophan requirements for male broilers in pre-starter and starter phases. Two experiments using 400 Cobb broilers were performed 200 males in the first experiment for the pre-starter phase (one to seven days old), and 200 males in the second experiment for the starter phase (eight to 21 days old). Chicks were housed in batter boxes made of galvanized steel as an experimental shed. The experiments were performed in a completely randomized design, with four treatments and five replicates, with ten birds each. In both experiments, the tryptophan requirement was determined using diets with different levels of digestible tryptophan. A tryptophan-deficient diet was formulated, as a basal diet, which was supplemented with increased levels of L-tryptophan in order to achieve the desirable digestible tryptophan levels. Treatments consisted of 0.209% (basal diet); 0.223%; 0.235% and 0.248% digestible tryptophan for the pre-starter phase (experiment 1) and 0.187% (basal diet); 0.200%, 0.211% and 0.223% digestible tryptophan for the starter phase (experiment 2). We evaluated feed intake, weight gain and feed conversion, as well as the metabolizability of feed nutrients. The performance and metabolic data were subjected to analysis of variance, and estimates of digestible tryptophan levels were made through polynomial regression models at 5% probability. There was no significant difference between the digestible tryptophan levels in the diet over performance and digestibility in both treatments. It is possible to conclude that the basal diet with 0.209% digestible tryptophan for the pre-starter phase and 0.187% for the starter phase, at a tryptophan: lysine ratio of 16%, as sufficient to meet the broilers requirements.
