Tujuan penelitian ini adalah Mengetahui perbedaan kualitas fisik telur hasil persilangan resiprok antara pejantan itik Tegal dengan betina Magelang (Gallang) dan pejantan itik Magelang dengan betina Tegal (Langgal). Materi yang digunakan dalam penelitian ini adalah 150 butir telur yang dihasilkan oleh 50 itik hasil persilangan antara pejantan itik Tegal dengan betina itik Magelang (Gallang) dan 150 butir telur yang dihasilkan oleh 50 itik hasil persilangan antara pejantan itik Magelang dengan betina itik Tegal (Langgal). Metode penelitian yang digunakan yaitu eksperimen. Data dianalisis menggunakan uji t. Variabel yang diukur kualitas fisik telur meliputi bobot telur, bobot kuning telur, bobot putih telur, haugh unit (HU), warna kuning telur, indeks telur, ketebalan kerabang. Hasil penelitian menunjukkan bahwa rataan bobot telur itik Gallang dan Langgal masing-masing yaitu 61,592±2,309 g dan 62,692±1,896 g, rataan bobot yolk Gallang dan Langgal masing-masing yaitu 18,951±1,491 g dan 19,511±1,569, rataan berat albumen itik Gallang dan Langgal masing-masing yaitu 33,568±1,669 g dan 34,640±2,482 g, rataan warna yolk itik Gallang dan Langgal yaitu 7,983±0,390 dan 8,08±0,444, rataan indeks telur itik Gallang dan Langgal masing-masing yaitu 81,189±1,945 dan 81,663±2,038, rataan ketebalan kerabang itik Gallang dan Langgal masing-masing yaitu 0,344±0,0268 dan 0,349±0,024, dan rataan  haugh unit itik Gallang dan Langgal masing-masing yaitu 96,779±2,239 dan 97,047±2,133. Hasil uji t menunjukkan kualitas fisik telur Gallang dan Langgal berbeda sangat nyata (P<0,01) pada bobot telur dan bobot albumen, berbeda tidak nyata (P>0,05) pada kualitas fisik telur yang meliputi bobot kuning telur, warna kuning telur, indeks telur, ketebalan kerabang dan haugh unit. Berdasarkan hasil penelitian disimpulkan bahwa kualitas fisik telur (bobot kuning telur, haugh unit, warna kuning telur, indeks telur, ketebalan kerabang) pada itik Gallang dan Langgal relatif sama kecuali bobot telur dan bobot albumen. Itik Langgal memiliki bobot telur dan bobot albumen lebih tinggi dibandingkan bobot telur dan bobot albumen Gallang.

The purpose of this study was to study the differences of the physical quality of eggs resulted from resiprocal cross between Tegal drake with Magelang duck (Gallang) and Magelang drake with Tegal duck (Langgal). The materials used in this study were 150 eggs which were resulted by 50 ducks from the cross between Tegal drake and Magelang duck (Gallang) and 150 eggs which were resulted by 50 ducks from the cross between Magelang drake and Tegal duck (Langgal). The method of this study used was experiment. The data were analyzed with t-test. Variables that measured by physical quality of eggs including the weight of eggs, egg yolks, egg whites, haugh unit (HU), the color of the egg yolks, index of eggs, eggshell thickness. The results of this study showed that the average of Gallang and Langgal eggs weight was 61,592±2,309 g and 62,692±1,896 g, the average of Gallang and Langgal egg yolks was 18,951±1,491 g and 19,511±1,569g, the average of Gallang and Langgal albumen weight was 33,568±1,669 g and 34,640±2,482 g, the average of Gallang and Langgal egg yolks color was 7,983±0,390 and 8,08±0,444, the average of Gallang and Langgal index eggs was 81,189±1,945 and 81,663±2,038, the average of the Gallang and Langgal eggshell thickness was 0,344±0,0268 dan 0,349±0,024, and the average of Gallang and Langgal haugh unit was 96,779±2,239 dan 97,047±2,133. The results of t-test showed that physical quality of Gallang and Langgal were significantly different (P<0,01) on the weight of eggs and weight of albumen, not significantly different (P>0,05) on the weight of egg yolks, the color of egg yolks, the index of eggs, the eggshell thickness, and haugh unit. Based on the result of the study, the physical quality of eggs (egg yolks weight, haugh unit, egg yolks color, index of the eggs, eggshell thickness) on the Gallang and Langgal ducks were relatively similar except the egg weight and albumen weight. Langgal ducks had the eggs and albumen weight higher than Gallang ducks eggs and albumen weight.
