Judul: The Production Performance and The Hatching of Alabimaster-1 Agrinak Duck Eggs Resulting from Different Male and Female Ratios
Abstrak: Pada program breeding itik petelur, rasio jantan-betina yang tepat sangat penting untuk memastikan stok bibit itik unggul untuk program pemuliaan. Rasio jantan-betina dipelajari untuk memastikan stok bibit itik unggul. Penelitian ini bertujuan untuk mengetahui pengaruh rasio jantan dan betina terhadap hen day production (HDP), fertilitas, daya tetas, mortalitas dan kualitas anak itik (day old duck/DOD) Alabimaster-1 Agrinak. Penelitian ini dilaksanakan dari Desember 2023 hingga Maret 2024 di BPSI-UAT. Sebanyak 84 itik berumur 19 bulan dibagi menjadi 4 kelompok perlakuan rasio jantan dan betina : P1 (1:3), P2 (1:5), P3 (1:7), dan P4 (1:9) dan dipelihara dalam 12 pan kandang koloni dengan alas litter (3 ulangan per kelompok). Itik diberi pakan dengan kandungan protein kasar 18%. Sebanyak 1212 butir telur tetas itik Alabimaster-1 Agrinak ditetaskan menggunakan mesin tetas otomatis Multiplo dengan sistem multistage. Rasio jantan dan betina tidak berpengaruh pada fertilitas, mortalitas, daya tetas, dan kualitas DOD namun berpengaruh terhadap HDP, dengan rasio 1:9 menunjukkan perbedaan tertinggi., In the layer duck breeding program, the appropriate male-female ratio is crucial to ensure a superior breeding stock for breeding programs. The malefemale ratio is studied to ensure the availability of superior breeding ducklings. This research aims to know the effect of male-female ratios on hen day production (HDP), fertility, hatchability, mortality, and the quality of day-old ducklings (DOD) of Alabimaster-1 laying ducks at Agrinak. The study was conducted from December 2023 to March 2024 at BPSI-UAT. A total of 84 ducks aged 19 months were divided into 4 treatment groups of male-female ratios: P1 (1:3), P2 (1:5), P3 (1:7), and P4 (1:9), and were housed in 12 colony cages with litter bedding (3 repetitions per group). The ducks were fed a diet containing 18% crude protein. A total of 1212 eggs of Alabimaster-1 Agrinak laying ducks were incubated using the Multiplo automatic incubation machine with a multistage system. Male-female ratios did not affect fertility, mortality, hatchability, and DOD quality but affected HDP, with the 1:9 ratio showing the highest difference.

Abstrak: Duck’s hatchery industry produces a diverse weight of Day old Duck’s (DOD) because the hatched eggs have diverse weight. The diverse of DOD weight indicates to cause affect to the performance of ducks. Research was conducted to measure the influence of hatching weight to performance of Alabio duck’s age 0 to 8 weeks. This research used 47 males and 96 females Alabio duck. Alabio’s DODs were separated based on hatching weight, that is small grade (34,39 ± 1.70), medium grade (38.57 ± 0.91), and large grade (43.12 ± 1.98). All ducks had same treatment and maintenance system. This research used randomized completely design with 2x3 factorials of sex and hatching weight. The observed variables ware consumption, average daily gain, weight cuts at 8th weeks, feed conversion, and mortality. From this research, hatching weights didn’t influenced to all performances, however sex can influence to daily gain, body weight at 8th weeks, and feed conversion. Male ducks have daily gain and body weight at 8th weeks bigger than female ducks. Male ducks have lower feed conversion than female ducks.
