Perbaikan mutu genetik dan peningkatan kualitas DOC dapat dilakukan melalui proses seleksi terhadap bobot telur tetas. Penelitian ini dilaksanakan pada bulan April hingga Juli tahun 2023 di Laboratorium Produksi Unggas Jurusan Peternakan Fakultas Pertanian Universitas Syiah Kuala, Darussalam. Banda Aceh. Rancangan yang digunakan adalah Rancangan Acak Lengkap (RAL). Perlakuan berdasarkan klasifikasi bobot telur yaitu: P0: Bobot Random, P1: ekstra besar (>60 g), P2: besar (56-60 g), P3: sedang (51-55 g), P4: kecil (46-50 g), P5: ekstra kecil (<46 g). Setiap perlakuan terdiri dari 4 ulangan, sehingga diperoleh 20 unit perlakuan dengan variabel yang diamati yaitu Daya Tetas, Berat Tetas dan Susut tetas. Hasil penelitian menunjukkan Persentase daya tetas yang paling tinggi terdapat pada perlakuan P3 (83.69%) berbeda sangat nyata (P<0,01) jika dibandingkan dengan perlakuan lainnya. Rataan berat tetas P1 (>60 gram) menunjukkan perbedaan yang signifikan sebesar 46.08 gram sedangkan rataan berat tetas terkecil pada perlakuan P5 (33.70 gram). Penyusutan telur tetas berada pada kisaran 10.84 – 15.10%, semakin besar bobot telur maka persentase susut semakin besar. Perlakuan P1 bobot telur mengalami penyusutan selama proses inkubasi berbeda sangat sigifikan (P<0.01) dibandingkan dengan perlakuan lainnya, penyusutan terkecil pada perlakuan P5 sebesar 10.84% tidak berbeda nyata (P>0.01) dengan perlakuan P3 dan P4. ABSTRACT Improving genetic quality and increasing DOC quality can be done through a selection process on hatching egg weight. This research was carried out from April to July 2023 at the Poultry Production Laboratory, Department of Animal Husbandry, Faculty of Agriculture, Syiah Kuala University, Darussalam. Banda Aceh. The design used was a Completely Randomized Design (CRD). Treatments based on egg weight classification are P0: Random Weight, P1: extra large (>60 g), P2: large (56-60 g), P3: medium (51-55 g), P4: small (46-50 g ), P5: extra small (<46 g). Each treatment consisted of 4 replications, so 20 treatment units were obtained with the observed variables: Hatchability, Hatching Weight, and Hatching Loss. The results showed that the highest percentage of hatchability was in the P3 treatment (83.69%), which was very significantly different (P<0.01) when compared to other treatments. The average hatching weight of P1 (>60 grams) showed a significant difference of 46.08 grams, while the average hatching weight was the smallest in the P5 treatment (33.70 grams). The shrinkage of hatching eggs is 10.84 – 15.10%. The more significant the egg weight, the greater the shrinkage percentage. In treatment P1, egg weight decreased during the incubation process, significantly different (P<0.01) compared to other treatments. The minor shrinkage in treatment P5 was 10.84%, not significantly different (P>0.01) from treatments P3 and P4.
