  • The Effect of Probiotic Addition in Commercial Feed to Growth and Survival Rate of Sangkuriang Catfishes (Clarias Gariepinus (Burchell, 1822))
    Available online at www.worldnewsnaturalsciences.com WNOFNS 21 (2018) 130-140 EISSN 2543-5426 The Effect of Probiotic Addition in Commercial Feed to Growth and Survival Rate of Sangkuriang Catfishes (Clarias gariepinus (Burchell, 1822)) Walim Lili, Rezky Hartanto*, Nia Kurniawati, Titin Herawati, B. S. Ibnu Bangkit Faculty of Fisheries and Marine Sciences Padjadjaran University, Bandung, Indonesia E-mail address: [email protected] ABSTRACT This study was conducted to determine the effect of probiotic addition in commercial feed to the growth and survival rate of Sangkuriang catfish (Clarias gariepinus). This research was conducted at the Ciparanje Experimental Pond Laboratory, Faculty of Fisheries and Marine Sciences, Universitas Padjadjaran, Jatinangor, West Java. The method in used this research was Completely Randomized Design with four treatments and four replications. The treatment was the variances of probiotic addition which consisted of control (without probiotics), probiotic addition at as much as 0.5 grams / kg of feed, 1 gram / kg of feed and 1.5 grams / kg of feed. The parameters observed were specific growth rate (SGR), absolute biomass, survival rate (SR) and feed conversion ratio (FCR). Data were analyzed using Variant Analysis, at 95% confidence level, and continued with Duncan's Multiple Range Test. The results showed that the increase in the daily growth rate of Sangkuriang catfish was straight-line with the addition of probiotics. Furthermore, commercial probiotics with a dose of 1 gram / kg of feed resulted in specific growth rate of 4.22%, absolute weight of 11 grams, survival rate (SR) of 97.5% and FCR of 0.89. Keywords: probiotic, Sangkuriang catfish, feed conversion ratio, specific growth rate, survival rate, Clarias gariepinus 1.

Chemical analyses of the samples were carried out in triplicate for dry matter (DM), moisture, ash, crude protein (CP), crude fiber (CF) and ether extract (EE) in the animal nutrition laboratory, Chittagong Veterinary and Animal Sciences University, Chittagong, Bangladesh during March to September, 2014 were collected, compiled and analyzed. Results indicated that , there were wide ranges of variations in chemical compositions for different parameters. DM contents varied from 95.4 to 93.5 g/100g and CP contents varied from 28.5 to 23.3 g/100g. similarly CF contents varied from 5 to 3.5 g/100g and EE contents varied from 6 to 4.4 g/100g. TA varied from 7.5 to 5.9 g/100g. It was concluded that, chemical composition of four estimated ornamental fish feed is widely variable. In this study no significant (p>0.05) relations were found in biochemical composition of the collected four feed samples.
