Performa Ayam Broiler yang Diberi Ransum Mengandung Bungkil Biji Jarak Pagar (Jatropha curcas L.) Hasil Fermentasi Menggunakan Rhizopus oligosporus
Abstract: Jatropha curcas meal
(JCM) contains high crude protein (58%-60%), but it can not be used properly
because of anti-nutritional contents known as curcin and phorbolesther. These
components interferes protein metabolism and body protein synthesis. This study
was conducted to evaluate the effect of feeding fermented JCM using Rhizopus
oligosporus on broilers' performances. Ninety six of day old chicks of Ross strain broiler (initial body weight
45.6±1.7 g) were used and reared for five weeks. The treatments were: R0 (diet
without JCM), R1 (diet contained 3% fermented JCM), R2 (diet contained 6%
fermented JCM) and R3 (diet contained 9% fermented JCM). A completely randomize
design with 4 treatments and 4 replications was assigned in this experiment.
The data were analyzed using analysis of variance (ANOVA). The results
indicated that feeding fermented JCM at the level of 3% to 9% in starter and
grower-finisher broilers highly significant reduced (P<0.01) feed
consumption, body weight and body weight gain. Feeding JCM at the level of 9%
(R3) highly significant increased (P<0.01) the mortality rate of starter as
well as grower-finisher period broilers. Fermentation of JCM using R.
oligosporus indicated no effective detoxification process in relation to the
improvement of broiler performances.
