Abstract

The research was conducted to study the growth characterization of Trichoderma reesei, the degradability of mannan polysaccharides from Palm Kernel Cake (PKC) with different concentrations of fungi and thickness of the PKC medium, as well as the improvement of the nutritive value of palm kernel cake. Experiment 1 was to study the growth characterization of Trichoderma reesei, and Experiment 2 was conducted using concentrations of fungi (104, 105, and 106 CFU per cc) and thickness of the PKC medium (1, 2, and 3 cm). The research used a completely randomized design with factorial 3 x 3. The treatments resulted in significant (P<0.05) differences on pH and temperature of PKC medium, ADF, NDF, crude protein, and hemicellulose.  There were interaction effect on the concentrations of fungi and on the thickness of PKC medium (P<0.05) on NDF, crude protein, and hemicelluloses (P<0.05). Experiment 3 was conducted to study the True Metabolizable Energy (TME), the retention of nitrogen, total sugar and mannan content. Results showed that Trichoderma reesei was able to degrade mannan polysaccharides of PKC whereby TME and the total sugar value increased, but the nitrogen retention and mannan content decreased.

Abstract

The research was conducted using lemuru fish oil and vitamin E supplementation in broiler chicken diet as an immunomodulator. The experiment design was used a completely randomized design with 3 x 3 factorial patern. Nine treatment diets were consisted of three levels of lemuru fish oil supplementation (0, 3, and 6%) as the first factor, and vitamin E supplementation (0, 100, and 200ppm) as the second factor and its combinations. All data were analyzed by analysis of variance and Duncan multiple ranges. There were no significant differences among treatments on antibody titers responses after first ND vaccination, but gave significantly differences on  antibody titers (P<0,05) after the second ND vaccination. There were interaction effects of dietary lemuru fish oil and vitamin E on the increasing of the antibody titers. There were no interaction effects of lemuru fish oil and vitamin E on antibody titers responses to IBD.  Vitamin E supplementation significantly increased (P<0,05) antibody titers responses to IBD, but not the lemuru fish oil supplementation. The amount of lymphocyte was significantly increased (P<0,05) due to the lemuru fish oil supplementation but not due to the vitamin E supplementation.

Abstract

This experiment was conducted to study the effects of katuk leave meal on sexual maturity in Japanese quail.  Three hundred female Japanese quails, with 4 weeks age, were assigned into a completely randomized design with 4 treatments i.e., R1 (diet with neither katuk leave meal nor cholesterin), R2 (diet without   katuk leave meal + 0.10% cholesterin), R3 (diet with 15% katuk leave meal without cholesterin), and R4 (diet with 15% katuk leave meal + 0.10% cholesterin). The parameters measured were estradiol hormone in plasma, and age maturity (five percent henday production). Estradiol hormone was measured with Radioimmunoassay. The data were collected and analyzed by using completely randomized design. The results showed that the addition of 15% katuk leave meal in the diet significantly decreased the estrogen concentration (P<0.05), so that slow down on the age maturity of female Japanese quail.
