Abstract

The duck farmers in Brebes Regency has not been able to deal with the business dynamics with themain problems in feed and Day Old Duck (DOD).The aim of the research was to analyze the businessperformance of duck farmer in Brebes Regency. The technical and economical efficiency was calculatedto find out the status of duck farmer?s business performance. The research was conducted to four mostactive duck farmer groups (KTTI) in Brebes Regency. The research was done based on survey methodwith 123 duck farmers of the group member as the respondents. The research results show that not all ofthe duck farmers performed their business efficiently (the average technical efficiency is 0.9981) sincethe number of duck ownership, forage, and the use of technology were not optimum yet. The return toscale value of the duck farming businesses was 1.0868, which showed the presence of opportunity toincrease production. This research recommends that it is necessary to manage the productionmanagement in order to increase business performance by optimizing the number of duck ownership,forage feed, and the use of technology.

Abstract

The aim of this research was to evaluate calcium deposition in egg using eggshell flour as a limestone substitute in feed. Two hundreds laying hen of Isa Brown strain of 25 weeks were used in this study. Treatments were diet with 7.5% limestone as control (T0), 2.5% limestone is substituted with eggshell flour(T1), 5% limestone is substituted with eggshell flour (T2) and limestone is substituted with eggshell flour (T3). A completly randomized design were used to allocated the treatments with 5 replications of each. Each experimental unit consists of 10 laying hens. Parameters measured were egg weight, yolk weight, albumen weight, eggshell weight, calcium of egg (yolk, albumen and eggshell), length, weight and Ca of tibia bone. The results showed that substitution of limestone with eggshell flour had significantly effect (P<0.05) on eggshell weight, Ca deposition on yolk, albumen, and Ca of tibia bone but non significantly effect on egg weight, weight and percentage of yolk, weight and percentage of albumen, percentage and Ca of eggshell, length and weight of tibia bone. In conclusion, calcium deposition in yolk was the highest in the use of 7.5% eggshell flour to substitute limestone but obtained the lowest Ca of bone , while calcium deposition in albumen was the highest in the use of 2.5% eggshell flour.

Abstract

An experiment was conducted to investigate the expired bread meal used as corn substitution in thebroiler diets to optimally the product performance. One hundred day old chick (DOC) male broilerswere given the same diet until 2 weeks old, and then given the treatment diet until 7 weeks of age. ACompletely Randomized Design was used in this study. Data were analyzed by variance of analysis, andfollowed by Duncan?s Multiple Range Test The treatments were : T0 = control feed (without expiredbread meal), T1 = corn substituted with 10% expired bread meal, T2 = corn substituted with 20%expired bread meal, T3 = corn substituted with 30% expired bread meal and T4 = corn substituted with40% expired bread meal. The result indicated that corn substituted with expired bread meal up to 40%has not significantly affected on carcass weight, carcass percentage and feed conversion, but decreasedsignificantly on feed consumption and body weight gain. It can be concluded that the use of expiredbread meal 30% of the proportion of corn produced the most optimal broiler performance. Thesubstitution corn with expired bread meal 40% was decreased body weight gain.

Abstract

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.

Abstract

The present research was aimed to evaluate an interactive effect of cage density and level ofdietary black cumin (BC) on productive efficiency of broiler chickens. A total of 270 broiler chickens(initial body weight of 163.12 ± 8.10g) were allocated into a completely randomized design with a 3 x 3factorial pattern. The first factor was the cage density (bird/m2) namely, D1 = 8; D2 = 10, and D3 = 12.The second factor was BC level (%), namely, B1 = 1; B2 = 2, and B3 = 3. Feed consumption, bodyweight gain (BWG), feed conversion ratio (FCR), protein digestibility, and income over feed cost(IOFC) were the parameters measured. Data were subjected to ANOVA and continued to Duncan test.No interaction between cage density and black cumin on all parameters was observed. Feedconsumption and FCR were increased, but BWG was lowered significantly (P<0.05) due to the cagedensities of 10 and 12 birds/m2 on weeks 2 and 3. Protein digestibility was significantly increased byfeeding 2 and 3% BC. IOFC decreased significantly (P<0.05) when cage densities were 10 and 12birds/m2. In conclusion, the improvement of productive efficiency of broiler chicken reared at the cagedensity of 12 birds /m2 can be sufficiently achieved by feeding 1% black cumin.

Abstract

The study aimed to determine the effect of kayambang leaves flour (Salvinia molesta) as aconstituent of broiler ration that contain omega-3 fatty acids, on body weight, percentage of abdominal fat and blood lipid profile including High Density Lipoprotein (HDL) and Low Density Lipropotein (LDL). The material used was 100 broiler chickens unsexied 15 days old with an average a body weight of 500 ± 6.99g. Ration treatment consisted of T0 (ration without Salvinia molesta leaf meal); T1 (ration with Salvinia molesta leaf meal 6 % ); T2 (ration with Salvinia molesta leaf meal 12 %); and T3 (ration with Salvinia molesta leaf meal 18 % ). The results of the study showed Salvinia molesta leaf meal in the ration of broiler chickens affect (P&lt; 0.05) body weight. Treatment T1,T2 and T3 showed decreases compared with the control diet (T0). Abdominal fat percentage showed no significant differences (P &lt;0.05). Increase in LDL from control to treatment and decrease HDL were found in this experiment. The conclusion states that the provision of Salvinia molesta flour up to 18 % decreased the live weight of broiler, but did not decrease abdominal fat percentage. The LDL blood was increased and HDL was decreased due to addition of Salvinia molesta flour.Key words: Salvinia molesta, broiler chicken, fat, blood
