The long period of raising carp (Osphronemus gouramy) causes the need for excessive feed. One way that can accelerate the growth of this fish in order to shorten the maintenance period is by the addition of essential amino acids, such as lysine. However, this certainly gives its own influence on energy retention. Therefore, the aim of this study was to determine the influences of addition of lysine in feed on energy retention and feed conversion ratio of carp. The research method used an experimental method with a completely randomized design consisting of five treatments and four replications. The treatments used were the addition of Lysine 0%, 1%, 1.5%, 2%, and 2.5% to the feed. The present experiment was conducted for a year. The results showed that the addition of lysine as much as 2% in commercial feed can increase the energy retention of carp (Osphronemus gouramy). Moreover, the addition of lysine by giving up to 2.5% cannot reduce the feed conversion ratio in carp (Osphronemus gourami) rearing. It can be concluded that the use of lysine has different effects related to the increase in retention and decrease conversion ratio in carp.

Tilapia cultivation has the potential to be developed in Indonesia, especially in South Sulawesi. However, the obstacle faced in tilapia cultivation is feed; the price is relatively high because the raw materials are still imported. One of the efforts to overcome dependence on imported feed raw materials is using local raw materials, namely rice bran. This study aims to determine the best type of probiotic in hydrolyzing rice bran flour into artificial feed on survival and conversion ratio of tilapia fish feed. This research was conducted in Sidenreng Rappang Regency. The test animals used were tilapia larvae with an average size of 1.03 g. The maintenance container is a tarpaulin pond with a size of 1 m x 1 m x 1 m filled with 85 L of freshwater. The study was designed using a completely randomized design consisting of four treatments and three replications. The fermenting materials used as treatment were Bacillus sp., Lactobacillus sp., Aspergillus nigers, Yeast (Acetobacter). The test feed was given to 20 tilapia larvae stocked in each container for 60 days of rearing. The survival data and feed conversion ratio for tilapia were analyzed using analysis of variance (ANOVA). The results showed that tilapia fed fermented rice bran feed using the fermenter Lactobacillus sp. had a significant effect on survival (SR) with a value of 85% and the feed conversion ratio (FCR) of tilapia with a value of 2.23.

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.

A total of (120) day old Bounty Fresh colored broiler chickens were carried out in a completely randomized design to evaluate the effect of different levels of oregano leaf meal (OLM) on the growth performance at a dietary levels of 0, 3 ,6 and 9% respectively.   Results showed significant in terms of cumulative feed consumption, gain weight and feed conversion ratio. Broilers given 6% of level of oregano (T3) had the heaviest body weight on the seven week of age with a mean 1955.25 grams while the lightest was those broilers without the supplementation of oregano leaf meal (T1) with a mean of 1743.75 grams. The inclusion of OLM as fed diet were the most efficient feed converter and therefore, has the potential to increase rapid growth and improve vitality and livability of colored broiler chicken. Insignificant result was obtained in terms of the percentage rate of growth, dressing percentage with and without giblets and feed conversion ratio as revealed by the analysis of variance. However, in terms of the income over feed and chick costs, Colored broiler chicken fed with 6% oregano leaf meal had the highest return of Php 88.89 and the lowest return was those broilers without oregano with a return of Php 50.47.The results suggest that OLM at 6% level can be safely used as feed ingredients to the broilers without any deleterious effect.
