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.

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

Upaya meningkatkan produktivitas itik lokal, sebagai penghasil daging telah banyak dilakukan baik melalui perbaikan pakan maupun perbaikan genetik dengan persilangan. Penelitian ini bertujuan untuk melihat  performa pertumbuhan, produksi karkas dan potongan karkas  itik persilangan Cihateup x itik Alabio (CA) jantan dan betina pada umur pemotongan 8 minggu.  Penelitian ini menggunakan analisis uji t student dengan membandingkan jenis kelamin jantan dan betina pada perlakuan yang sama. Hasil penelitian menunjukkan bahwa itik persilangan CA jantan memiliki bobot hidup akhir (BHt), bobot potong, bobot karkas serta persentase karkas paha secara statistik lebih besar (P<0,05) dibandingkan dengan itik CA betina, sedangkan konsumsi, konversi pakan dan persentase karkas dada tidak berbeda.
