One of the information needed by farmers is information about nutrition ration poultry in accordance with the Indonesian National Standard (SNI). This study aims to determine the value of energy metabolism in commercial chicken rations. Determination of energy metabolism was conducted by Farrel in which chickens were fed like a chicken eating chicken feed itself and previously fasted for 24 hours and still be drinking. The ration of treatment used is feed corn, feed rations BR1 and BR2. Chickens were given time for 2 hours to eat the feed later in the fasting. After fasting rationing and the chicken will issue feces, to prevent the evaporation of nitrogen in the feces spraying by the use of H2SO4 concentration 0,01%. Chicken feces then dried and analyzed by the laboratory using a bomb calorimeter. The data in the analysis of variance (ANOVA) and Duncan test. Corn research results show that the energy metabolism in the feed ration obtained BR1 3.048 kcal/kg and BR2 3.237 kcal/kg. The result can be concluded that the value is in compliance with EM EM minimum value required in SNI minimum of 2.900 kcal / kg with a value of EM listed on the label.Keywords:  Energy Metabolism, Commercial feed, Corn

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.

Duck egg is known to have an unpleasant fishy odor which often becomes a factor reducing its acceptance in public.  This odor is resulted from lipid oxidation which can be avoided by using an antioxidant.  This study was aimed at assessing the effects of the inclusion of star gooseberry (Sauropus androgynus) dried leaf extract in ration on egg organoleptic quality of local duck.  The study was conducted in a completely randomized design with 4 treatments and 4 replicates.  Sensory test by 60 semi-trained panelists and hedonic quality and hedonic tests were conducted.  Data were subjected to a Kruskal-Wallis test.  Results showed that treatments gave significant effects (P <0.05) on aroma (hedonic), yolk color, and aroma (hedonic quality).  It was concluded that the inclusion of star gooseberry dried leaf extract by 1,5% in ration improved the quality of egg yolk color, egg aroma, and consumers’ preference.  A further study on the effects of DSGLE on meat quality and protein digestibility in ducks was recommended.

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.

Penelitian ini bertujuan untuk mengkaji pengaruh tepung indigofera yang diberikan ke pedet terhadap KCBK, KCBO, dan SK. Penelitian menggunakan RAL dengan perlakukan sebagai berikut: Ro) Kosentrat 40%+Hijauan 60% R1) Hijauan 60% + (5% tepung indigofera + 35% konsentrat R2) Hijauan 60%+(10% tepung indigofera + 30% konsentrat . Hasil penelitian mengungkapkan bahwa pedet FH yang diberi ransum Konsentrat+Hijauan (rumput gajah)+ tepung indigofera tidak berpengaruh nyata  (P>0,05).
