Compared to other animals, duck has some superiority as it is relatively more resistant to diseases and easier to raise. Garcinia leaf contains high hydroxycitric acid which is an organic acid known to have antilipidemic and antiobesity properties. This study was aimed at assessing the effects of the inclusion of garcinia leaf meal in rations in different length of time on sensory quality of meat of culled ducks. The study was conducted at the poultry farm of Department of Animal Science, Djuanda University, Bogor in 30 June to 4 August 2019. Sixteen culled female ducks were used in a completely randomized design with 4 treatments and 4 replicates. Four ducks were allocated to each treatment. Treatments consisted of the inclusion of 0% garcinia leaf meal in rations (R0, control) and 6% garcinia leaf meal in rations which were fed to the birds within 1 week (R1), 3 weeks (R2), and 5 weeks (R3). Data were subjected to a Kruskal Wallis test. Results of the hedonic test showed that the inclusion of garcinia leaf meal in rations gave significant effect (P<0.05) on meat taste but not (P>0.05) on meat aroma, tenderness, color, and juiceness. Meanwhile, results of panelis assessment in the hedonic quality test showed that significant differences (P<0.05) were found in meat tenderness, taste, and juiceness. It was concluded that duck meat color was improved with the inclusion of garcinia leaf meal in rations for 1 week and meat fishy smell was reduced with the inclusion of garcinia leaf meal in rations for 3 weeks.

Ducks are still less liked by consumers because the quality of production is still low compared to broilers. To improve this quality, additional feed can be in the form of herbs which are thought to have content for this. Asam gelugur leaves contain hydroxycitric acid and active substances that act as antioxidants. So that it is expected to improve the quality of the carcass. The purpose of this study was to examine the effect of giving asam gelugur leaf meal on the percentage and composition of male and female ducks in the grower phase. The study was conducted for 2 months in the Poultry Farm of Faculty of Agriculture, Djuanda University. The 40 grower ducks consist of male and female. Fourty male and female grower ducks were allocated into a 2 x 4 completely randomized factorial design. Factor A consisted of sexes (male and female) and factor B consisted of levels of asam gelugur leaf meal inclusion in rations (0, 2, 4, and 6%). five replicates were used for each treatment. The variables observed were slaughter weight, carcass weight, carcass percentage, commercial cut percentage of carcass and duck carcass composition. The results showed that there was no interaction and there was no significant difference (P> 0.05) from giving asam gelugur leaf meal to carcass percentage, carcass commercial cut percentage and duck carcass composition. The conclusion of this study is that giving asam gelugur leaf meal to males and females can maintain the quality of the carcass and the composition of the local duck carcass.

One of the sources of animal protein for the community can be obtained from quail eggs. Quail eggs have nutritional value that is not inferior to other poultry eggs. Feed is one of the factors that can affect egg quality. Coriander is a spice that contains essential oils that are beneficial for the body when consumed. So it is hoped that the presence of this essential oil can help improve livestock growth and produce quality quail eggs sensory. This study aimed to examine the effect of giving coriander flour to quail feed on the sensory quality of eggs. The study was conducted for 30 days. The livestock used were Japanese quail aged 30 days with 100 heads. The feed used is commercial feed and additional coriander flour. The design used was a completely randomized design with 4 treatments and 5 replications for each unit of 5 birds with treatment R0 = commercial feed +0% coriander flour, R1 = commercial feed + 0.5% coriander flour, R2 = commercial feed + 1% coriander flour, R3 = commercial feed + 1.5% coriander flour. Data were analyzed using Kruskall Wallis and Duncan's multiple range test. The results showed that the administration of coriander flour had a significant effect (P<0.05) on the hedonic test of egg white color and texture hedonic quality test, while for the egg yolk color, taste, aroma variables were not significantly different (P>0.05). This study concludes that organoleptic administration of 1% coriander flour can increase the panelists' preference for egg whites and improve the texture of quail eggs.

Compared to chickens, ducks still have low productivity and other limitations. One of the causes of these problems might be attributed to the off-odor found in duck meat. Therefore, production performance and meat quality of ducks need to be improved. The inclusion of extracts of betel (Piper betle Linn) leaves and torch ginger (Etlingera elatior) flowers wereas done to improve production performance and meat quality of local ducks. This study was aimed at assessing the effects of the inclusion of betel leaves and torch ginger flowers in the basal rations on production performance and meat quality of local ducks in the growing phase. A completely randomized factorial design in 4 x 4 with three replicates was used. The first factor consisted of four levels of torch ginger flower solution, namely 0, 2.5, 5, and 7.5%. The second factor consisted of four levels of betel leaf solution, namely 0, 2.5, 5, and 7.5%. Results showed that no significant differences (P>0.05) were found in body weight gain, feed intake, feed conversion, mortality rate and meat quality (pH, water holding capacity, tenderness and cooking loss). It was concluded that the inclusion of extract of betel leaves and torch ginger flowers did not improve production performance and meat quality of male local ducks.

Meat quality represents meat properties known by consumers and affects their acceptance. Feed is one of the factors affecting meat quality. Utilization of pineapple waste as a fiber source in cattle feeding is potential to reduce feed cost. Pineapple waste can be used as feed and as meat tenderizer. However, many believes that feeding pineapple waste to cattle distract beef quality. This study was aimed at assessing meat sensory quality of Brahman Cross cattle fed pineapple waste as fiber source. Six Brahman Cross (BX) cattle aged 2.5-3 years were used. The cattle were fattened for 120 days. Three cattle was fed rations containing concentrate and pineapple waste silage and the remaining cattle was fed rations containing concentrate and corn leaf silage. In the end of the study period, the animals were slaughtered and meat was cut based on the commercial slaughtering standard. Meat samples of Longissimus dorsi muscles were taken. Beef sample aging was conducted at 0ºC for 3 months. Measurements of beef characteristics were taken monthly. A completely randomized design was used. Data were subjected to a Kruskal Wallis test and meat physical characteristics were analysed by repetaed measurement analysis of variance. The parameters observed comprised pH values, tenderness, cooking loss, water holding capacity, meat colors (L*, a*, b* value), organoleptic test hedonic and hedonic quality (aroma, tenderness, color, and mucus). The results showed that the pineapple waste did not have significant influences on meat physical characteristics observed, except meat color a* values at two month aging, meat color L* value at three month aging. It was concluded that pineapple was could be used as a fiber source in beef cattle fattening with no negative effect on meat quality.

Quail eggs are a source of animal protein that the public can consume. In addition to the low price, eggs also contain nutrients needed by the body. So it is necessary to pay attention to the quality of the eggs before consuming them. Egg quality that can be assessed is derived from internal and external quality. The quality of the eggs is influenced by various factors, including the content of the ratio given, especially the energy-protein balance of the feed. This study aimed to assess the external and internal quality of quail eggs with different protein and energy levels. The research was carried out for 42 days in the poultry house of the Animal Husbandry Study Program, Faculty of Agriculture, Djuanda University. The feed ingredients formulated in this study as the basic ration were yellow corn, fine bran, soybean meal, fish meal, premix, DCP, CaCO3, CPO, and Cr-O. The design used was a completely randomized design (CRD) with four treatments and four replications with six quails per cage unit. The research data were analyzed by analysis of variance (ANOVA) if the data showed significantly different results (P<0.05), followed by Duncan's test. The variables observed in this study were egg weight, shell weight, percentage of eggshell weight, eggshell thickness, egg index, egg white weight, egg yolk weight, egg white weight percentage, egg yolk weight percentage, Haugh unit (HU). The results showed that the balance of energy and protein differences were not significantly different in all variables. Based on the research results, it can be concluded that the quail ration with the balance of protein 17% and metabolizable energy 2800 kcal/kg has been able to maintain the internal and external quality of eggs in quail and produce standard egg quality.Keywords: protein energi balance; egg white, yolk, haugh unit

Duck meat is a source of protein from poultry which can be used to meet human animal protein needs. This is because duck meat has good nutritional content like chicken meat. However, duck meat is less favorable than chicken meat. Utilization of rejected ducks (Cairina Moschata) is still very limited. Refined duck meat has a characteristic odor, namely off odor and a rough and tough texture, so it requires separate handling so that it can be used further. Utilization of male or rejected duck meat has not been widely developed in the wider community. Meat tenderness is influenced by connective tissue protein, the older the livestock, the amount of connective tissue is greater, causing the meat to become tough or tough. This condition causes the rejected livestock to have a low selling price. Processing of meat and eggs can improve organoleptic and increase the variety of processed forms, allowing the preparation to be available at all times and save time and effort before the food is ready to be served. Bojongkerta Village has potential in duck farming. Ownership of land for farmers is relatively broad and is supported by less dense community settlements. However, the potential of the area is not supported by adequate.
