Effect of Tropical Alfalfa (Medicago sativa L. cv Kacang Ratu BW) on the Blood Profile in Hybrid Ducks

Abstract This study aimed to determine the effect of the use tropical alfalfa (Medicago sativa L. cv Kacang Ratu BW) meal in feed on the blood profile in hybrid ducks. 72 day-old duck were reared for 42 days using stage cages. Ducks were randomly divided into three treatments with four replications and each of the replication consisted of six hybrid ducks. The treatment in this study used tropical alfalfa powder in formulated basal diet with different levels. The study was conducted with three treatments including AL0: 0% tropical alfalfa (control), AL4: 4% tropical alfalfa, and AL8: 8% tropical alfalfa. The feed was given at the age of eight days and adapted to the needs of the ducks. Data observed were blood profile in the form of total erythrocytes, total leukocytes, hemoglobin levels, hematocrit values, heterophil levels, lymphocyte levels and H/L ratio of hybrid broiler ducks. All data obtained were analyzed using descriptive statistical analysis. Statistical analysis used nonparametric tests using Kruskal-Wallis and further tests using Man Whitney for data that were significantly different between treatments. The results showed that the use of tropical alfalfa meal had no significant effect (P>0.05) on total erythrocytes, total leukocytes, hemoglobin levels, hematocrit values, heterophil levels, lymphocyte levels and H/L ratio of hybrid broiler ducks. It can be concluded that the use of tropical alfalfa meal up to 8% in hybrid duck feed did not effect on blood profile.

The Egg-Turning Technique on The Hatching Performance of Hybrid Duck Eggs

This research aimed to determine different egg-turning techniques on the hatching performance of hybrid duck eggs. The materials for this research include water, hatching eggs of hybrid ducks, and manual hatching machines. This research used the T-test with 2 treatments and 6 replications, including T1 (swipe egg-turning) and T2 (manual egg-turning), each replication consisting of 10 hatched hybrid duck eggs. The parameters observed included the percentage of mortality, the percentage of hatchability, and the hatching weight of hybrid ducks. Analysis of the resulting data uses an analysis of variance (ANOVA) with the SPSS (Statistical Package for Social Science) application. Data that had significant differences were then tested further using the DMRT test (Duncan Multiple Range Test). The results showed that the egg-turning technique had no significant effect on the hatching performance of hybrid duck eggs, including mortality, hatchability, and hatching weight. The conclusion of the research was the regular turning times with differences in egg-turning techniques did not influence the hatchability of the duck hybrid.

Effect of Cichorium intybus on production performance, carcass quality and blood lipid profile of hybrid duck.

One hundred hybrid male ducks (Mojosari×Alabio) were used to examine the efficacy of chicory supplementation as nutritional feed manipulation on production performance, and blood lipid profile of hybrid ducks. The ducks were tagged, weighed, and then allotted randomly to one of the four treatment diets using a completely randomized design. The experimental diets were: 1) P0 (100% basal diets + 0% chicory as control), 2) P1 (95% basal diets + 5% chicory), 3) P2 (90% basal diets + 10% chicory) and 4) P3 (85% basal diets + 15% chicory). For each treatment group, there were 5 replicates of 5 birds each. All experimental diets were isonitrogenous and isocaloric using locally available ingredients. Hybrid ducks with fed diets supplemented fresh chicory (5, 10, and 15%) showed increased feed intake and body weight gain, as well as feed conversion ratio to be smaller than those ducks fed diets without chicory supplementation (control). The ducks fed 10% chicory supplementation contained significantly (p<0.05) lower ash and higher organic matter contents of meat than those ducks fed other diets. The ducks fed 15% chicory supplementation showed the lowest crude protein and cholesterol content of meat among the treatment diets. Ducks fed chicory supplementation showed lower (p<0.05) blood cholesterol and triglyceride levels than those ducks fed without chicory supplementation, while dietary interventions had no major (p>0.05) influence on low-density lipoprotein and high-density lipoprotein levels in duck blood. In this study, 10% chicory supplementation showed the best results characterized by an increase in growth performance, carcass quality, small intestinal histomorphology, and lower cholesterol levels of meat.

Broiler ducks are ducks that are able to grow quickly and can convert feed efficiently into meat with high value. Duck meat has a good structure and structure of the meat. The good structure of duck meat is now popular with the public, because the taste of the meat is delicious and savory. Broiler ducks that are known by the public include hybrid ducks and peking ducks. The demand for duck meat that continues to increase does not change with the availability of duck meat available in the market, to meet the needs of the community. It is possible to breed broiler ducks as proof that the poultry business for ducks is wide open with the promised profit prospects. The purpose of this study was to determine the productivity in broiler duck cultivation which can increase body weight gain quickly, economically and produce meat that has high nutrition to meet public demand. The research method used is literature review by analyzing relevant articles and focusing on the productivity of broiler duck farming. Based on maintenance for 6 weeks, the data obtained was the consumption of hybrid rations as much as 6,514 g/head while in peking ducks as much as 7,601 g/head, PBB in hybrid ducks was 1,237 g/head, while for peking ducks 1,699 g/head, FCR in ducks hybrid 5.29 and peking duck 4.49 and mortality of hybrid duck 4% and peking duck 12%. The weight gain, mortality, and feed conversion of peking ducks were higher than that of hybrid ducks. The conclusion from the results of the study that the best duck genotype to produce FCR was hybrid duck and production performance which included body weight gain, feed consumption and feed conversion in peking ducks and hybrid ducks.

Effect of High-Voltage Electrostatic Field Heating on the Oxidative Stability of Duck Oils Containing Diacylglycerol.

High-voltage electrostatic field (HVEF) as an emerging green technology is just at the beginning of its use in meat products and by-products processing. In this study, we employed duck oil to produce duck-oil-based diacylglycerol (DAG), termed DDAG. Three different DDAG volume concentrations (0, 20%, and 100%) of hybrid duck oils, named 0%DDAG, 20%DDAG, and 100%DDAG, respectively, were used to investigate their thermal oxidation stability in high-voltage electrostatic field heating and ordinary heating at 180 ± 1 ℃. The results show that the content of saturated fatty acids and trans fatty acids of the three kinds of duck oils increased (p < 0.05), while that of polyunsaturated fatty acids decreased (p < 0.05) from 0 h to 8 h. After heating for 8 h, the low-field nuclear magnetic resonance showed that the transverse relaxation time (T21) of the three oils decreased (p < 0.05), while the peak area ratio (S21) was increased significantly (p < 0.05). The above results indicate that more oxidation products were generated with heating time. The peroxide value, the content of saturated fatty acids, and the S21 increased with more DAG in the duck oil, which suggested that the oxidation stability was likely negatively correlated with the DAG content. Moreover, the peroxide value, the content of saturated fatty acids and trans fatty acids, and the S21 of the three concentrations of duck oils were higher (p < 0.05) under ordinary heating than HVEF heating. It was concluded that HVEF could restrain the speed of the thermal oxidation reaction occurring in the duck oil heating and be applied in heating conditions.

Tropical alfalfa (Medicago sativa cv. Kacang Ratu BW) supplementation for reducing cholesterol and improving quality of carcass and meat of hybrid duck

Context Duck meat is a good source of protein (21.4%) but it is high in cholesterol, with a standard range of 125–200 mg/dL. Alfalfa is a legume that contains saponins, which have been shown to reduce the cholesterol content of meat. Aim We aimed to determine the effect of alfalfa on the weight of the internal organs and carcass, the physicochemical quality of meat, and the cholesterol of hybrid ducks in Indonesia. Methods Ninety 1-day-old Indonesian hybrid ducks were fed basal rations supplemented with 0% (control), 3%, or 6% fresh alfalfa (n = 5 per group), calculated on a dry matter basis. Five replicates were made for each dietary treatment. Dietary treatments were administered to the ducks from 8 to 35 days of age. The parameters measured were the internal organ weight, carcass quality (live weight, carcass weight, carcass percentage, and abdominal fat), physicochemical quality of meat (water content, crude protein, crude fat, pH, water holding capacity [WHC], cooking loss, and tenderness), and the cholesterol content of the liver, breast meat, thigh meat, and blood (including the high-density lipoprotein/HDL and low-density lipoprotein/LDL). Analysis of variance and Duncan’s multiple range tests determined the significance of results. Key results Supplementation of rations with up to 6% of alfalfa did not significantly affect the weight of the internal organs, but reduced the cholesterol content in the liver, meat, and blood. In addition, the physicochemical parameter of alfalfa supplementation in the rations, up to a level of 6%, had no effect on carcass quality, moisture content, crude protein or pH of hybrid duck meat. Moreover, supplementation with 6% of alfalfa significantly reduced the LDL levels while increasing the HDL and affecting crude fat, WHC, cooking loss, and tenderness of hybrid ducks. Conclusions Supplementation with up to 6% of alfalfa did not affect the weight of key internal digestive organs, but reduced the cholesterol content, and increased the HDL levels of blood. Alfalfa supplementation affected the physicochemical quality of hybrid duck meat. However, the optimum level (production parameters observation) of alfalfa supplementation in the diet was at 3%. Implications Hybrid duck meat exhibits lower cholesterol, higher HDL, and lower LDL when the diet is supplemented with alfalfa, whereas other parameters were largely unchanged.

&lt;p class="abstrak2"&gt;In this experiment, we investigate the effect of modified banana tuber meal (M-BTM) to substitute dietary maize in growing-finisher colored-feathered hybrid duck. One hundred and ninety six hybrid ducks (Pekin x Khaki Campbell) with 421.31 ± 0.183g body weight (BW) were allotted to 5 dietary treatments with 9 ducks (unsexed) per pen and 4 replications per treatment. These dietary treatments were: NC (negative control; maize-soyabean-meal based diet), BTM25 (25% maize was replaced by M-BTM-), BTM50 (50% maize was replaced by M-BTM), BTM75 (75% maize was replaced by M-BTM), and BTM100 (100% maize was replaced by M-BTM). The experimental design applied using completely randomize design (CRD). Data of this experiment were statistically analysed by one-way-analysis-of-variance of SAS University version 4.0 red hat (64-bit) University Online Edition. Result demonstrated that M-BTM improved significantly (p&amp;lt; 0.05) digestibility of dry matter and crude protein. It is concluded that M-BTM enhanced apparently growth performaces and digestibility parameters of colored-feathered hybrid duck (Pekin x Khaki Campbell).&lt;/p&gt;

The effect of hay alfalfa (Medicago sativa L.) supplementation in different basal feed on the feed intake (FI), body weight, and feed conversion ratio of hybrid ducks

This study was conducted to determine the effect of hay alfalfa supplementation (Medicago sativa L.) in different basal feeds on the feed intake (FI), live weight (LW), Feed Conversion Ratio (FCR), and income of Hybrid Duck. In vivo trial was conducted with 120 MA hybrid ducks (Mojosari x Alabio), based on completely randomized design (CRD). Three (3) treatments and 6 replications with each repetition consisted of 5ducks. The treatments were P1 = radom mixed feed, P2 = 90% radom mixed feed + 10% hay alfalfa and P3 = 90% alternative feed + 10% alfalfa hay. Feed was obtained in dry matter but offered as fed. Feed and drinking water was offered ad libitum. The observed variables included feed consumption, live weight, feed conversion ratio (FCR), and income over feed cost. The data obtained were analyzed with the application of Statistical Product for Service Solution (SPSS) version 22 and if there was significant differences in treatment it would be further tested using Duncan’s Multiple Range Test (DMRT). The results showed that 10% alfalfa supplementation in free mixed feeds and alternative feeds showed a significant effect (P <0.05) on the value of feed consumption, but not with the other variables. Based on these results it can be concluded that three type of feed has similar potential as feed for duck. However, radom mixed feed treatment with 10% alfalfa hay supplementation (P2) is the most optimum treatment among the other treatment feeds, due to the highest live weight income value.
