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.

Judul: Nisbah Jenis Kelamin Hasil Penetasan Telur Itik Cihateup dan Alabio
Abstrak: Duck eggs are more difficult to hatch than chicken eggs as the duck does not incubate their eggs and the duck eggs need more time to hatch (in 28 days). This study aimed to determine the sex ratio of DOD (Day Old Duck) from two different breeds, namely cihateup from Tasikmalaya West Java and alabio from South Kalimantan. This experiment was conducted from May 2012 to July 2012 at the Hatchery Laboratory of Animal Science Faculty of IPB. 500 eggs consist of 300 alabio eggs and 200 cihateup eggs were used in this experiment. Temperature, humidity, egg weight, egg shape index, hatching weight and mortality were measured. The data of egg weight, egg shape index, and hatching weight were analyzed using t-test, the data of sex ratio DOD were analyzed using chi-square test. The result showed that there were no significant difference between egg weight and egg shape index on sex ratio. Sex ratio of male and female cihateup ducks was equal (50%:50%), however the sex ratio of alabio ducks was different (32%:68%). Mortality rate was affected by sex of duck (P<0.05). The Higher mortality was occured at early (day 0-7) and late (day>25) hatching period.
