The objective of this study was to evaluate the effect of noni (Morinda citrifolia) leaf shoot meal (NLSM) supplementation in the ration on the performances of kampong chickens as well as lipid, malondialdehyde (MDA), and fatty acid contents of meats. Two hundred and forty kampong chickens of 4 weeks old were reared until 12 weeks old. The diet treatments were R0: 0% NLSM (control), R1: 0.5% NLSM, R2: 1% NLSM, R3: 1.5% NLSM, R4: 2% NLSM, and R5: 2.5% NLSM. A completely randomized design (CRD) was used with six treatments and four replications with ten kampong chickens per replicate. The data were analyzed using ANOVA and if there were significant different, the data were further analyzed using Duncan’s Multiple Range Test. The variables measured were performances of kampong chickens as well as lipid, MDA, and fatty acid contents of meat. The result showed that cholesterol and LDL contents of meat were significantly reduced by feeding NLSM. Performance and HDL contents of meat were not significantly different for all diet treatments. In addition, feeding kampong chickens with ration supplemented with NLSM could reduce MDA, saturated fatty acids and increase unsaturated fatty acids contents of meat. It is concluded that 2.5% NLSM can be used to improve meat quality of kampong chicken as functional meat.

The objective of this study was to evaluate the effects of sweet-potato leaves and cassava leaves inclusions into the diet containing lemuru oil on lipid metabolism of local laying ducks. One hundred and eighty laying ducks with an average body weight of 1657 g were divided into 6 groups of experimental diets with 3 replications and 10 ducks in each replication. The experiment was arranged in a 2 x 3 factorial design. The first factor was the level of sweet potato leaves consisted of 2 levels, i.e., 0% and 5%. The second factor was the level of cassava leaves consisted of 3 levels, i.e., 0%, 5%, and 10%. The variables observed were performance of laying duck, blood, meat, and egg lipid profile, as well as the relationship between the average consumption of β-carotene with cholesterol concentration in the blood, egg, and meat of laying duck. The results showed that there was no interaction and no effect between sweet potato leaf meal (SPLM) and cassava leaf meal (CLM) on feed consumption. Different levels of SPLM and CLM gave a significant interaction effect (p<0.05) on body weight gain, with the best interaction, was 5% SPLM combined with 0% CLM (26.60 g/duck). There was also a significant interaction effect between the combination of 5% SPLM and 10% CLM (p<0.05) for reducing the cholesterol, triglyceride, and LDL concentrations in the blood, meat, and egg. Different levels of SPLM and CLM gave significant interaction effects (p<0.05) on the fat contents of flash in laying duck. The fat content of the liver was significantly decreased by 5% treatment of SPLM (p<0.05). Meat fat decreased significantly with a combination of 5% SPLM and 10% CLM (p<0.05). Treatments with 5% SPLM or 10% CLM reduced blood MDA (p<0.05), while treatments with 10% CLM reduced the MDA in the liver (p<0.05). It can be concluded that the combination of 5% SPLM and 10% CLM in the diets was effective as a source of antioxidants to protect unsaturated fatty acids in the blood, meat, and egg of ducks based on the reduced concentrations of cholesterol, triglyceride, and LDL.

The objective of this study was to evaluate the effect of feeding cassava leaf meal and golden snail on performances, chemical, and physical qualities of local duck egg. The experiment used 180 Pajajaran laying ducks of 20 weeks of age and was offered dietary treatments up to 26 weeks of age. The experiment was conducted in a completely randomized design with a 3 x 2 factorial arrangement. The first factor was the treatment of cassava leaf meal consisted of 3 levels, i.e., 0%, 5%, and 10%. The second factor was the treatment of golden snail consisted of 2 levels, i.e., 0% and 10%. Each experimental unit used three replicates and each replicate consisted of ten ducks. The results showed that there was no interaction effect of cassava leaf meal and golden snail treatments on laying duck performances and egg qualities. There were significant effects of cassava leaf meal and golden snail treatments (p<0.05) on egg production, feed intake, egg mass, egg index, and egg yolk color. However, egg weight, feed conversion ratio, yolk fat, yolk cholesterol, and yolk TBARS values, albumen weight, eggshell weight, shell thickness, and Haugh unit values were not affected (p>0.05) by treatments of cassava leave meal and golden snail. The utilization of 10% cassava leaf meal in the diet significantly improved egg production, feed intake, egg mass, and yolk color (p<0.05). The lowest egg index was found in the eggs produced by ducks fed diet containing 5% cassava leaf meal, but it is still within the normal range. Ducks fed a diet containing 5% golden snail significantly had higher feed intake, egg mass, percentage of albumen, and yolk color. It was concluded that there was no interaction effect of cassava leaf meal and golden snail treatments on laying duck performances and egg qualities. A diet containing 10% cassava leaf meal or a diet containing 5% golden snail had the greatest effects on the performance and physical quality of egg without affecting the chemical quality of the egg.

Zinc is one of the essential minerals that are important for poultry. The disadvantage of Zn in the conventional form is its low bioavailability. One of the efforts to increase the bioavailability of Zn is to make it in a nano form. Nano Zn-Phytogenic (NZP), is a combination of Zn and phytogenic compounds of plants in nanoparticle size. The NZP was self-produced utilizing the green synthesis process of inorganic Zn and guava leave extract (Psidium guajava). The objective of this study was to evaluate the effects of supplementation NZP in diet on the performance, antioxidant status, and population of pathogenic intestinal bacteria (Escherichia coli and Salmonella sp) of broilers chicken. This study used 180 males and 180 females of Lohman broilers day old chick (DOC). The experiment was subjected to a completely randomized design with 6 (six) treatments and 5 (five) replications, and each experimental unit consisted of 12 DOCs (6 males and 6 females). The treatment given in this study were; R1= basal diet; R2= R1 + Zn Sulfate (90 mg Zn/kg) + 5.32 mg/kg guava leaf flour with 12.82% water content (added as a source of phytogenic compounds); R3= R1 + NZP (45 mg Zn/kg); R4= R1 + NZP (90 mg Zn/kg); R5= R1 + NZP (135 mg Zn/kg); R6= R1 + NZP (180 mg Zn/kg). The variables observed were performance, antioxidant activity in meat, and population of pathogenic intestinal bacteria (E. coli and Salmonella sp) of broiler chicken. The results showed that the addition of NZP up to a dose of 90 mg Zn/kg in the diet improved (p<0.05) body weight gain compared to the basal diet. The addition of NZP had no significant effect on the FCR. The addition of NZP increased (p<0.05) SOD activity in meat when compared with the dietary treatment without NZP. Groups of chicken fed NZP (R3, R4, R5, R6) had significantly (p<0.05) lower E. coli and Salmonella sp population. It could be concluded that the addition of NZP up to a dose of 90 mg Zn/kg in the diet of broiler chicken had positive benefits in improving performance, increasing antioxidant activity, and reducing pathogenic intestinal bacteria (E. coli and Salmonella sp).

The study aimed to determine the efficacy of dietary vitamin E and fish oils on performance, carcass yield, cholesterol, omega-3, and omega-6 in the meats of broiler chickens. A total of 400 Lohmann day-old broiler chicks consisted of 200 males and 200 females were reared for 35 days. This experiment employed a completely randomized design with five treatments and four replicates. The treatments were T0: Control diet with 3% crude palm oil without vitamin E; T1: Diet containing 3% fish oil; T2: Diet containing 3% fish oil and 80 IU/kg vitamin E; T3: Diet containing 3% fish oil and 100 IU/kg vitamin E, and T4: Diet containing 3% fish oil and 120 IU/kg vitamin E. The result showed that dietary fish oil and vitamin E had no effect (p>0.05) on feed intake, body weight, weight gain, AME, AMEn, TME, and TMEn, but it tended to decrease the mortality rate. T3 significantly reduced (p<0.05) FCR in the finisher phase and meat cholesterol compared to the control. T1 and T3 significantly (p<0.05) reduced carcass weight percentage. Dietary fish oil and vitamin E increased omega-3 levels, and declined the ratio of omega-6 and omega-3. It is concluded that supplementation of 100 IU Vitamin E in the diet containing 3% fish oil improved feed efficiency by 9.95%, decreased cholesterol of the meat by 44.76%, increased omega-3 of the meat by 81.92%, and yielded the best ratio of omega-6: omega-3 of the meat, i.e., 10.34:1.

Indonesian local ducks are commonly raised for egg production purposes. However, the performances of these ducks are still variable and must be improved. This study investigated the effects of turmeric, curcuma, and probiotic supplementations on the egg production and quality of Indonesian local ducks, emphasizing the eggs’ fatty acid profile. Two hundred female local ducks aged 16 weeks were randomly allotted to four dietary treatments with five replicates of 10 birds. The ducks were fed a corn and rice bran-based diet containing different supplements, i.e., a diet without supplementation as the control diet, a diet supplemented with turmeric at the level of 4%, a diet supplemented with curcuma at the level of 4%, and a diet supplemented with starbio probiotics at the level of 2%. The measured data were analyzed using analysis of variance using the 13 Systat program and continued with Duncan’s Multiple Range Test. Turmeric supplementation increased egg production compared with the control, and the duck fed probiotics consumed more feed than the control. Curcuma supplementation generated the lowest feed consumption, egg production, and physical egg quality than the other treatments (p<0.05). The probiotics supplementation enhanced the blood high-density lipoprotein concentration (p<0.05). Turmeric, curcuma, and probiotics supplementations generate variable responses in egg production and egg quality, including the fatty acid profile in the eggs. Turmeric and probiotics supplementations positively impact egg production, egg quality, or unsaturated fatty acid profile in the egg. However, curcuma supplementation decreased egg production and egg quality of local ducks. Furthermore, the fatty acid profile was not influenced by these supplements. It is concluded that supplementation of turmeric at the level of 4% and probiotics at the level of 2% in the diet can increase egg production and egg quality of local duck.
