The research objective was to compare crude protein and crude fat digestibility of fermented product of palm kernel cake (80%) and rice bran (20%) mixture with those of unfermented product mixture. Student-t test was applied to determine the difference between the two treatments, while crude protein and crude fat digestibility were determined following the procedure of Coen et al. (1996). The results of the study showed that the crude protein digestibility of fermented product was higher (P<0.05) than that of unfermented product (84.96±2.43% vs 65.60±2.39%) or increased by 19.36%. The average crude fat digestibility increased (P<0.05), from 69.22±3.14% in the unfermented product to 85.08±2.04% in the fermented product or increased by 15.86%. In conclusion, process of fermentation significantly improved nutritive value of mixture of palm kernel oil (80%) and rice brand (20%) for broiler in terms of higher crude protein and crude fat digestibility.

This research aimed to study the effect of protein level and lysine supplementation on bone growth of native chicken by the age of 6 weeks. The materials used were unsexed DOC of native chicken with average body weight 25.2 ± 1.0 g. Research was carried out in 2 x 3 factorial arrangement according to completely randomized design. There were 4 replications for each treatment combination with 10 chickens for each experimental unit. The treatments were P1L1 (17% protein + 0.6% lysine of the ration ), P1L2 (17% protein + 0.7% lysine of the ration), P1L3 (17% protein + 0.8% lysine of the ration ), P2L1 (14% protein + 0.6% lysine of the ration), P2L2 (14% protein + 0.7% lysine of the ration), P2L3 (14% protein + 0.8% lysine the ration). Treatments were applied starting from the age of day 1 to 6 weeks of age. Parameters measured were femur length, femur weight and femur bone strength. Data were analyzed by analysis of variance followed by Duncan’s multiple range test at 5% probability level if there was a significant effect of treatment on the parameters. There was a significant interaction (P <0.05) between the level of protein and lysine supplementation affecting the femur length and femur bone weight, but there was no interaction (P> 0.05) effects on the femur bone strength. Based on these results, it was concluded that the optimal growth of native chicken bones were obtained from the ration containing 17% protein and 0.8% lysine supplementation.

PENGARUH PENGGUNAAN TEPUNG AMPAS KECAP DALAM PAKAN AYAM PETELUR FASE MENJELANG AFKIR TERHADAP KADAR PROTEIN DAN VITAMIN A, SERTA MASSA PROTEIN TELUR (The Usage Effect of Soy Sauce Waste Product in Feed of Laying Hens on Protein and Vitamin A Percentage, and Protein Mass of Egg) D.

The study was aimed to examine the effect of soy sauce waste product in in the diet of laying hens on protein percentage, protein mass and vitamin A percentage of whole eggs also income over feed cost (IOFC). The material used were 200 birds of Lohman Brown at 80 weeks old, with average body weight 1.932,75±189,50 g. Feed ingridient were yellow corn, rice bran, soybean meal, fsh meal, meat bone meal, poultry meat meal, lysine, methionine, limestone powder, premix and soy sauce waste product. The experimental design used was completely randomized design (CRD) with 4 treatments and 5 replications, total 20 unit experiments and each unit contains 10 laying hens. The observed variables were protein percentage, protein mass and vitamin A percentage of whole eggs. The data was analyzed using analysis of variance (ANOVA) with F test, if there are signifcant effect of treatment continued to Duncant test. The result showed that the usage of soy sauce waste product in diet of laying hens were signifcantly (p<0,05) decrease protein percentage and protein mass of whole egg, but did not effected on whole egg vitamin A. Soy sauce waste product can be used as laying hans feed until 15% with the higher IOFC.

Bioaccumulation of Pb and Cd on Broiler Chicken Fed in Difference Diets Bambang Dwiloka; U. Atmomarsono; V. Priyo Bintoro; B. Widianarko

The study was aimed to compute Pb and Cd bioaccumulation in different organs of broiler. Carcass, heart, liver, gizzard, intestine, and excreta. The data were obtained from broiler reared in the litter cage. Four treatments of feed were given to the broiler chicken, i.e. T1 = X brand of commercial feed, T2 = Y brand of commercial feed, T3 = self-prepared feed without fish meal addition and T4 = self prepared feed without fish meal but contaminated with cadmium chloride (Cd.Cl2.4H2O). For each treatment, five broiler chicken were grouped each week (from week I up to week VI). Results of the first stage of this study was analyzed descriptively. A polinomial regression equation was used as an empirical model to describe the heavy metal bioaccumulation phenomenon in broiler carcasses. The quadratic equation turned out to be the most suitable model for describing the bioaccumulation of heavy metal in broiler carcasses. From the simulation, it was found that quadratic model fit to 61.31% and 54.17% bioaccumulation data of Pb and Cd respectively. According to the model, initially metal concentrations declined since the first week and started to rebound at the fifth week, both in terms of chronological and physiological age. The patterns of Pb and Cd bioaccumulation in this study can be used as a reference to determine the proper slaughter period. It can be concluded that for reducing the risk of metal contamination the proper slaughter time of the broiler is before the fifth week.
