Defatted Rice Bran

This work aimed to study the potential of defatted rice bran (DRB) and defatted soybean meal (DSM) as carbon and nitrogen sources for Lactococcus lactis growth and nisin production. First, a maximum nisin yield of 3630 IU/mL was achieved using 40% DRB hydrolysates and 30% DSM hydrolysates, which was 1.13 times greater than that found in commercial media. Second, to simplify the operation and shorten the length of the entire process, the processes of combined hydrolysis of DRB-DSM followed by fermentation, and simultaneous hydrolysis and fermentation of DRB-DSM were developed. Neutral proteinase enhanced the saccharification of DRB by cellulase and α-amylase. Furthermore, the strategy of NADH oxidase expression and hemin addition was innovatively proposed to overcome the oxygen stress in a simultaneous hydrolysis and fermentation process, which could alleviate the lag period following inoculation of L. lactis and result in a 77.3% increase in nisin titer.

Abstract. The objective of present study was to determine effect of feeding tilapia  fishes (Oreochromis niloticus) with the commercial diets partially substituted by Organic Pelet Feed  (OPF) composed by cattle feces,  soybean meal, rice bran, and probiotic on total income.  The study was conducted  in  Research Station II Ie Sueum,  Syiah Kuala University,  June 1 until  August 29,  2016.  The study used 1600 of  a week old of tilapia fish.  The study was performed into completely randomized design (CRD) consisting of 4 treatments and 4 replications.  Each replication was an experimental unit, consisting of 100 fishes.  The treatment tested was feeding tilapia fishes with  commercial diets partially substituted by OPF with the level of  0, 10, 20, and 30%, respectively.  The OPF was made up of cattle feces 50%+rice bran 30%+soybean meal 19%+probiotic 1%.  Parameters measured were final body weight (FBW),  total feed consumption (TFC), and Income Over Feed Cost (IOFC) as well as total income.  The data of  FBW and TFC were analyzed by Analysis of  Variance (ANOVA) (Ott, 1993), while  the data of IOFC and total income were analyzed by the economical parameters of R/C and B/C ratio (Soekartawi, 1995).  The results of study showed that OPF could be used up to 20% to substitute commercial diet in raising tilapia fish with the best level was  10% most significantly (P0,01) increasing body weight of tilapia fish.  It was considered that the highest income of  raising tilapia fish was resulted by administrating 10% OPF.

This study was conducted to determine the effect of cottonseed meal (CSM) incorporated into laying rations in place of soybean meal (SBM) at different ratios on yield traits. The birds began to lay at 6th week, 180 female and 45 male quails were used in laying period experiment. Birds were fed with rations containing 20% CP and 3000 Kcal/kg ME up to 20-week age (Laying period). CSM as a substitute, five different rations of the protein content (0, 30, 58, 86 and 100%) for SBM to basal diets based on corn-soybean meal were used. The results showed that there were no differences in terms of egg yield traits, cumulative feed consumptions and viabilities during the laying period. The highest dry shell rate and shell thickness were obtained from 5th group and 1st group, respectively. As a result, adding CSM instead of SBM in laying period were no significantly differences in terms of egg production and egg quality in laying period.
