Daftar Isi:
- Tujuan dilakukan penelitian ini adalah untuk mengetahui pengaruh penambahan Lactobacillus sp., terhadap pertumbuhan berat, panjang, SR (Survival Rate) dan FCR (Feed Convertion Ratio) udang vaname (Litopenaeus vanamei). Penelitian ini dilakukan menggunakan 4 (empat) perlakuan dan 3 (tiga) ulangan dengan perlakuan P1 = (7%), P2 = (9%), P3 = (11%) dan P4 = (13%). Lokasi penelitian di Desa Kidang dan Laboratorium Mikrobiologi Fakultas Pertanian, pada tanggal 30 April-13 Mei tahun 2019. Pemeliharaan udang selama 45 hari kemudian diukur parameter atau pengaruh perlakuan hasil penelitian menunjukkan bahwa penambahan bacteri Lactobacillus sp. sebagai berikut : pertumbuhan berat terendah yaitu pada P1 = 6,3667±0,17g/ekor sedangkan tertinggi pada P4 = 7,6±0,23g/ekor, pertumbuhan panjang terendah yaitu pada P1 = 4,4067±0,41cm/ekor sedangkan P4 = 5,4067±0,12cm/ekor, SR (SurvivalRate) terendah terdapat pada P1 = 76,6% sedangkan tertinggi pada P3 = 83,0% dan FCR (Feed Comvertion Rate) terendah terdapat pada P3 = 2,6067±0,15 sedangkan tertinggi terdapat pada P1 = 2,6067±0,15.
- Vaname shrimp has several advantages compared to tiger shrimp that is they are more resistant to disease. Vaname shrimp can be maintained with a very wide salinity range, that is between 0.5-45 ppt.One of the deep problems in vaname shrimp cultivation is the growth of Vaname shrimp which is very slow due to inappropriate management of feed.The purpose of the study is to know the effect of the addition of Lactobacillus sp to the growth of weight, length, SR and FCR Vaname shrimp (Litopanaeus vanamei).This study was conducted using 4 (four) treatments and 3 (three) replications with treatment P1 = (7%), P2 = (9%), P3 = (11%) and P4 = (13%) research location was in Kidang Village and Microbiology Laboratory, Faculty of Agriculture, on April 30-May 13 2019. Plant for 45 days and by measuring the parameters or treatment effects.The results showed that the addition of Lactobacillus sp. as follows,the lowest weight growth is at P1 = P1 = 6,3667±0,17g / head while the highest is in P4 = 7,6±0,23g / head,the lowest weight growth is at P1 = 4,4067±0,41 while P4 = 5,4067±0,12, the lowest SR is at P1 = 76.6% while the highest at P3 = 83.0% and the lowest FCR is at P3 = 2,6067±0,15 while the highest is at P3 = 2,6067±0,15.
