Abstract

This study was conducted to determine the effect of various calcium and phosphorus levels on theproduction performance of Bantul Duck. A total of 270 female ducks, 26 weeks age, were used in thestudy with a 3x3 factorial treatment, which is a combination of three levels of Ca: 3.75; 3.25 and 2.75%and three levels of P: 0.45, 0.35 and 0.25%. Each treatment occupied three replication cages, each ofwhich consisted of 10 ducks. The experiment was conducted for 12 weeks.. Data recorded were: (a) feedintake (g/duck/day), (b) egg production (% HDA), and (c) feed conversion. All quantitative dataobtained during the study were analyzed by analysis of variance (ANOVA) using SPSS computerprogram. The results of the variables recorded did not show significantly difference. Increasing Ca levelon feed showed an increasing trend of egg production. The average feed consumption ranged at 151-159g/duck/day; egg production was 75-84%, and the feed conversion was 184-212 g/egg.

Abstract

The research was aimed to evaluate the performance of laying hens fed different calcium sources.Two hundreds of Isa Brown laying hens were used in this study. The hens were raised in individualbattery cages units for 12 weeks. Four calcium source (limestone as a control, 5% limestone + 2.5%eggshells waste, 2.5% limestone + 5% eggshells waste and 7.5% eggshell waste) were used in feedexperiment. A completely randomized design was applied, with 4 treatments and 5 replications. Eachexperimental unit consisted of 10 laying hens. The parameters measured were feed intake, proteinintake, calcium intake, phosphorus intake, egg production, egg weight and feed conversion ratio. Resultsof the research showed that the calcium source had significantly effect on performance productions. Theuse of eggshell waste 7.5% significantly increased the feed intake, calcium intake, phosphorus intake,egg production and egg weight except for feed conversion ratio. The conclusion of this research was thatthe use of eggshell waste as calcium source of feed resulted in better performance than using limestoneor mixed limestone with eggshell waste.

Abstract

The purpose of the research was to assess the effect of α-tocopherol and ascobic acids on the performance and immunity blood profile of male native Muscovy duck. The materials used were 84 male Muscovy ducks at 9 weeks old. The research used completely randomized design with 7 treatments. The treatments were E0C0 : basal diet without α-tocopherol and ascobic acids, E400: basal diet+ α-tocopherol 400IU, E600: basal diet+α-tocopherol 600IU, C400: basal diet+ascorbic acid 400mg/kg, C600: basal diet+ascorbic acid 600mg/kg, E200C200: basal diet+α-tocopherol 200IU+ ascorbic acid 200mg/kg, and E300C300: basal diet+α-tocopherol 300IU+ ascorbic acid 300mg/kg. Each treatment was repeated 4 times and each replication consisted of 3 ducks. The observed variables were body weight, feed consumption, feed conversion ratio, packed cell volume (PCV), total of plasma protein (TPP), leucocyte count, basophil, heterophil, eosinophil, monocyte, lymphocytes count and heterophil/lymphocyte (H/L) ratio of Muscovy duck. The result indicated that E0C0, E400, E600, C400, C600, E200C200 and E300C300 had no significant difference in body weight, feed intake and feed conversion. There were significant effects on PCV, leucocyte count, percentage of heterophil and lymphocytes, but had no significant effect on eosinophil, monocyte and the H/L ratio. The C400 resulted a higher PCV count, percentage of heterophil, and H/L ratio. The C 600 produced the highest leucocyte count. In conclusion, the supplementation of ascorbic acid at 400 - 600 mg/kg feed ascorbic acid could improve theimmune profile, but could not improve the performance of Muscovy duck.

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

This study was aimed to develop nanoparticle formulation using turmeric extract and industrialchitosan as the polymer and sodium-tripolyphosphate as cross linker, to evaluate its ability to improvetrue metabolizable energy on broiler chicken. Forty eight of broiler chickens with an average bodyweight of 900 g, were randomly divided into 8 treatments (one treatment was fasted and 7 were fedration plus feed additive), containing six birds per treatment. The formulation of nanoparticle in thisstudy used ionic gelation method. Method used to evaluate the metabolizable energy was totalcollection. Chickens were fasted one day before and after they were treated with rations. Nitrogen, grossenergy and total weight of feed and excreta or ileal digesta released were analyzed to calculate the truemetabolizable energy of the ration. It was found that the basal ration added with nanocapsule 0.1% hadtrue metabolizable energy (3370.66 kcal/kg) significantly higher (P<0.05) than basal ration (3214.85kcal/kg). The result of this study concluded that formulation of nanocapsule using turmeric extract andindustrial chitosan as the polymer and sodium-tripolyphosphate as cross linker was potential to increasetrue metabolizable energy so it can be an alternative for broiler chicken feed additive.

Abstract

This research was aimed to improve the physical and chemical quality of Alabio ducks which was fed with Pomacea canaliculata snails. Those ducks were raised intensively. There were nine treatments  included R0 (control feed), R1 (control feed + 2.5% Pomacea canaliculata snails from swampy area), R2 (control feed + 5% Pomacea canaliculata snails from swampy area), R3 (control feed + 7.5% Pomacea canaliculata snails from swampy area) R4 (control feed + 10% Pomacea canaliculata snails from swampy area) R5 (control feed + 2.5% Pomacea canaliculata snails from tidal swampy area), R6 (control feed + 5% Pomacea canaliculata snails from tidal swampy area, R7 (control feed + 7.5% Pomacea canaliculata snails from tidal swampy area, and R8 (control feed + 10% Pomacea canaliculata snails from tidal swampy area. The variables observed included meat chemical and physical quality. A Completely Randomized Design was used in this study. Analysis of variance and Duncan’s multiple range test were used to analyze data. The research results revealed that using Pomacea canaliculata snails in duck feed had a significant effect (P<0.05) towards the physical characteristics (water holding capacity, cooking loss, and tenderness), and chemical characteristics of Alabio duck meat (water, protein, collagen, fat, and cholesterol content). However, there was no significant effect towards meat pH. It can be concluded that using 5% Pomacea canaliculata snails in a mixture of Alabio duck feed decreased cooking loss and meat cholesterol content.

Abstract

The aim of this study was to investigate the different of plumage colors on morphological diversityof Magelang duck and genetic diversity using PCR-RFLP mtDNA D-loop region analysis of Magelangduck and four others native duck population (Tegal, Mojosari, Bali and Alabio duck) in Indonesia. Bloodsample was taken from 50 Magelang ducks and 20 of each native ducks. Morphological characteristicsof body measurement, production ability and egg quality of Magelang duck were analyzed usingCompletely Randomized Design with 11 plumage colors as treatments. PCR technique was administeredto amplify fragments in mtDNA D-loop region and PCR products were digested with endonucleaserestriction enzyme AluI and HaeIII. The result showed that morphology diversity of Magelang duck wasstatistically affected by different plumage colors. PCR-RFLP analysis using AluI and HaeIII restrictionenzyme resulted in six combinations of restriction fragment pattern shown in six haplotypes (A, B, C, D,E and F). Haplotype difference showed genetic diversity in the population of Magelang duck and theother native ducks. In conclusion, the different plumage colors affected morphology diversity ofMagelang duck. Genetic diversity of Indonesian native duck population could be identified by usingPCR-RFLP analysis on mtDNA D-loop region.
