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%.

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.

To study responses to divergent selection for lean growth rate (LGA), lean food conversion ratio (LFC) and daily food intake (DFI), an experiment was started in 1984 at Edinburgh and Wye. This paper measured the selection pressure applied, the responses in the selection criteria and estimated the genetic and phenotypic relationships between the selection criteria with ad-libitum feeding of Landrace pigs after four generations of selection.The LGA (LFC) selection objective was to obtain equal correlated responses in growth rate (food conversion ratio) and carcass lean content, measured in phenotypic s.d. The LGA, LFC and DFI selection criteria had phenotypic s.d. of 32, 29 and 270 units and results are presented in s.d. units.Boars and gilts were purchased from eight British nucleus herds and boars from national artificial insemination centres in 1982. Homozygous or heterozygous halothane positive pigs were not included in the experiment. The base population consisted of 20 sires and 89 dams. Within each of the three selection groups, there were high and low selection lines with a control line, each consisting of 10 boars and 20 gilts, with a generation interval of one year. There were two control lines, one for LGA and one for LFC and DFI, as selection groups were arrowed continuously. The total number of pigs tested per line and average inbreeding coefficient at generation 4, within selection group are given below.

Summary1. An experiment involving 64 individually-penned pigs (32 females (gilts) and 32 castrated males (barrows)) was conducted over the live weight range 50 to 83 kg, to study the effects of a parenterally administered anabolic steroid upon the performance and carcass measurements of gilts and barrows given either a 15·0% or an 18·8% crude protein (CP) diet at two different levels.2. The steroid significantly improved both daily weight gain (+5·2%) and food conversion ratio (+4·8%) of gilts and barrows.3. There were no significant treatment interactions for either daily weight gain or food conversion ratio, but the data suggest that gilts responded to the hormone to a greater extent than barrows at the particular dose level of the steroid administered.4. The steroid significantly improved the carcass, as assessed by linear backfat measurements, of pigs given the higher CP diet but had no effect upon carcass measurements of pigs given the lower CP diet.
