Efek Pemberian Bungkil Biji Jarak Pagar (Jatropha curcas L.) Difermentasi Rhizopus oligosporus terhadap Kualitas Telur Puyuh

Abstract

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.
