Abstrak: Jatropha curcas meal (JCM) is potential as feed, its contain 22,35% crude protein. However anti-nutrients contained in the JCM as phorbolester and curcin (lectin) led to low protein availability. It’s need to detoxify, so that JCM safe as feed ingredient. So far, the most efficient detoxification method for JCM was with combination treatments of physical and biologically. The purpose of this study was to examine the eggs quality of laying Japanese quail (12-14 weeks) fed of Jatropha curcas meal fermented using Rhizopus oligosporus (JCMF). A completely randomize design with 5 treatments and 3 replications (10 quail per replication) was used in this experiment. The parameters observed were egg weight, persentage of egg components (proportions of yolk, albumen and shell to the weight of whole egg), and interior quality of eggs (shell thickness, Haugh unit, and yolk colour score). The data were analyzed using analysis of variance (ANOVA), and if any significant differences among treatments, the data were further analysed using Duncan Multiple Range Test. The results indicated that feeding JCMF at level of 9% and 12% significantly reduced (P<0,05) egg weight. Feeding JCMF at level of 12% significantly reduced (P<0,05) percentage of albumen, however feeding JCMF at level of 6% to 12% significantly increased percentage of yolk. Feeding JCMF up to level of 12% had no significantly influences on percentage of egg shell and interior quality of eggs (shell thickness, Haugh unit, and yolk colour score). The conclusion of this research was that JCMF could be used up to 6% in the laying quail diets.

Judul: Pengaruh Pemberian Bungkil Biji Jarak Pagar (Jatropha curcas L) Terfermentasi Rhizopus oligosporus dalam Ransum terhadap Performa Broiler
Abstrak: The major problem in broilers industry is feed availability and continuity. Jatropha curcas L meal is one alternative feed of poultry because it contains high crude protein, but it can not be used properly because of curcin and phorbolester contained in the meal that interfence the protein synthesis in the body. The present study was conducted to study the effect of feeding fermented Jatropha curcas L meal in the diet on feed consumption, body weight, body weight gain, feed conversion ratio and mortality. The research used 96 Day Old Chicks (DOC) Ross strain which were reared for five weeks. The treatment diets were: R0 (0% fermented Jatropha curcas L meal), R1 (3% fermented Jatropha curcas L meal), R2 (6% fermented Jatropha curcas L meal) and R3 (9% fermented Jatropha curcas L meal). This research used Completely Randomize Design with 4 treatments and 4 replications, each replication contained 6 broilers The data were analysed using Analyses of Variance (ANOVA). The significant results were further tested using Duncan's Multiple Range Test. The research result indicated that feeding fermented Jatropha curcas L in starter and grower-finisher period at the level of 3% (R1), 6% (R2) and 9% (R3) highly significantly reduced (p<0.01) feed consumption, body weight and body weight gain compared to that of control diet (R0). Feed conversion ratio in starter period at the level of 6% (R2) and 9% (R3) highly significantly increased (p<0.01) compared to that of control diet (R0). The mortality of broilers at starter period indicated that feeding Jatropha curcas L at the level 9% (R3) highly significantly increased (p<0.01) mortality compared to that of control (R0). At grower-finisher period indicated that feeding Jatropha curcas at the level 6% (R2) and 9% (R3) highly significantly increased (p<0.01) mortality compared to that of control (R0). Detoxification Jatropha curcas L with fermented using Rhizopus oligosporus has not effective yet to improve the broiler performances.
