Abstract

Besides chewy, red in color, duck meat also have a distorted smell (fishy/off-odor). For consumers who are not familiar, the smell is not preferred. Duck meat contains high unsaturated fatty acids. Unsaturated fatty acid is an ingredient which is prone to oxidation. Two strains: Alabio and Cihateup ducks were used in this study, each consist of 3 replications. Four treatments were: 1. Commercial diet without antioxidant (control = K0); 2. Beluntas leaf meal (0.5%) + commercial diet (KB) 3. Beluntas leaf meal (0.5%) + commercial diet + Vitamin C 250 mg / kg (KBC), 4. Beluntas leaf meal (0.5%) + commercial diet + vitamin E 400 IU/kg (KBE). This experiment was designed in Completely Randomized Design. The result showed that response of Alabio and Cihateup duck to feed treatment in saturated fatty acid content and unsaturated fatty acids in meat and skin of the same, namely the feed treatment of KBE high and low of KBC. Beluntas leaf meal as much as 0.5% + vitamin E in the feed could be reduced the intensity of off-odor and maintain good performance of duck.

Abstract

One effort for improving the productivity of Indonesian local ducks in particular as a meat types is by crossing among the local ducks. Crossbreeding is a fast breeding program for improving some commercial traits. Crossing between two lines or different breed are often used in production systems to utilized the advantage of heterosis (hybrid vigor). Crossbreeding is expected to produce new synthetic strains of duck that perform better than their parents. This study aims to utilize the heterosis and determine best cross, and to study the performance changes due to crossbreeding. The statistical design used in this study was a randomized complete design (RCD) consisting of 4 treatments with 6 replications, each replication consisting of five ducks. The treatments used were the crossing of the pure Cihateup ♂ x Cihateup ♀ (CC), line Alabio ♂ x Alabio ♀ (AA), Alabio ♂ x Cihateup ♀ (AC) cross as well as Cihateup ♂ x Alabio ♀ (CA) cross. This study using male ducklings first hybrid (F1). The results show that the CA is better than AC in the final live weight (7.05%), weight gain (7.32%), carcass weight (9.24%) and carcass yield (2.55%). Fleshy carcass cuts such as breast meat of AA (6.13%) is better when compared to the others, but the highest percentage of meat percentage of the thigh is the AC (10.13%). Duck crossesing CA possess superior properties more and economic value compared with the duck AC. Key Words: Alabio Duck, Cihateup Duck, Crossing, Heterosis, Performance

Abstract

The study was carried to identify the phenotypic variation of Alabio duck (Anas platyrhynchosBorneo) being kept by smallholder. This research was conducted in Hulu Sungai Selatan (HSS), HuluSungai Tengah (HST) and Hulu Sungai Utara (HSU), South Kalimantan from May until November2009. Six hundreds (75 males and 525 females) duck characterized in this study was age ranged from5-5.5 months old. The observed parameters were plumage color, color feature, plumage shine, the colorof bill, feet and shank. The results showed that the ducks from three locations (HSS, HST and HSU)performed different plumage color and color feature. The dominant plumage color of the Alabio maleduck was grayish white on the neck (44-56%), grayish black on the back (40-60%) brownish grey onthe chest (52-80%), while the wing was more dominated by blue-green (56%) and black (80%) in thetail. Whereas the female ducks was dominated (70-100%) brown spotted color, the rest blackish gray attail, such as back, neck and chest. Twinkle Alabio duck plumage on males and females have the highestpercentage was the glint of silver (100%) and of shiny blue-green for males (85-100%). The percentageof phenotypic color of bill, feet and shank of male and female ducks were lite yellow (40-60%), brightorange (12-44%), pale yellow (8-28%) and black (4-12%).

Abstract

The aims of this study were to obtain information on the mechanism of molting and the prolactinhormone levels affecting egg production. The study utilized AP (crossbred of Alabio ♂ with Peking ♀)and PA (crossbred of Peking ♂ and Alabio ♀ ducks) with a total of 180 birds. The observed variableswere the duration of cessation of egg production before and after molting, the prolactin hormone level inthe period of molting, the egg production period before and after molting. The data was analyzed usingANOVA, regression and correlation. The results showed that AP crossbred had fewer molting (23.33%)compared to PA (50.00%). The mechanism of molting is always preceded by cessation of eggproduction, molting and relaying. The prolactin hormone concentrations of AP and PA in the periodbefore and after molting were significantly higher than in the period of molting. At the egg productionperiod before molting, the prolactin hormone concentration of AP ducks was higher than the PA ducks.So that the egg production of AP before molting (0-16 weeks) was higher than the PA. The eggproduction of AP was higher than PA, 256.66±6.00 vs 232.22±6.64 eggs for 48 weeks. So it can beconcluded that the prolactin hormone affects the molting and egg production.
