Karakteristik Struktur dan Morfometri Usus Besar Itik Bali pada Pertumbuhan Fase Starter, Grower, dan Finisher. (Indonesian)

CHARACTERISTICS OF THE STRUCTURE AND MORPHOMETRY OF THE BALI DUCK LARGE INTESTINE IN STARTER, GROWER, AND FINISHER PHASES. (English)

Bali duck (Anas sp.) is a native germplasm to Indonesia which is used for its meats and eggs. The existence of bali ducks has not received special attention regarding the basic structure and morphometry of life-supporting organs, especially the large intestine. As the period of growth, the organs of bali ducks experience the development of weight and structure. This causes differences in the structure and morphometry of the large intestine at different ages. This study used male bali ducks with three age groups representing each phase, especially the starter phase (1 month), the grower phase (3 months), and the finisher phase (5 months). Left and right caecum and colon 1 month old bali ducks measurement results include length, wide, and weight were 14.65±0.65 cm, 1.16±0.23 cm, 1.10±0.32 g; 13.70±0.87 cm, 1.01±0.24 cm, 0.96±0.41 g; and 8.05±0.74 cm, 1.76±0.28 cm, 2.32±0.11 g. Left and right caecum and colon 3 month old bali ducks were 15.43±1.65 cm, 1.05±0.06 cm, 1.83±0.20 g; 13.83±1.59 cm, 1.03±0.10 cm, 1.83±0.20 g; and 9.08±0.81 cm, 2.15±0.26 cm, 4.66±0.88 g. While the left and right caecum and colon 5 month old bali ducks were 18.45±1.34 cm, 1.09±0.96 cm, 2.16±0.32 g; 17.63±1.32 cm, 1.05±0.05 cm, 2.05±0.42 g; and 10.33±1.50 cm, 2.21±0.23 cm, 5.25±0.38 g. From the results of the study, it can be concluded that the anatomical and histological structures of each age are not different, but from the morphometric observation it can be concluded that the age difference has a significant effect on increasing the morphometry of the large intestine anatomy of bali ducks.

Itik bali (Anas sp.) merupakan plasma nutfah asli Indonesia yang dimanfaatkan daging dan telurnya. Keberadaan itik bali masih kurang mendapat perhatian secara khusus mengenai struktur dan morfometri dasar organ penunjang kehidupan, khususnya usus besar. Seiring masa pertumbuhan, organ itik bali mengalami perkembangan bobot dan struktur. Hal ini yang menyebabkan adanya perbedaan morfometri pada usus besar di umur yang berbeda. Penelitian ini merupakan penelitian observasional noneksperimental dengan metode rancangan acak lengkap menggunakan itik bali jantan dengan tiga kelompok umur yang mewakili setiap fase pertumbuhan, yaitu fase starter (1 bulan), fase grower (3 bulan), dan fase finisher (5 bulan). Hasil pengukuran sekum kiri dan kanan serta kolon itik bali umur satu bulan meliputi panjang, lebar, dan bobot secara berturut-turut yaitu 14,65±0,65 cm, 1,16±0,23 cm, 1,10±0,32 g; 13,70±0,87 cm, 1,01±0,24 cm, 0,96±0,41 g; dan 8,05±0,74 cm, 1,76±0,28 cm, 2,32±0,11 g. Sekum kiri dan kanan serta kolon itik bali berumur tiga bulan berturut-turut yaitu 15,43±1,65cm, 1,05±0,06 cm, 1,83±0,20 g; 13,83±1,59 cm, 1,03±0,10 cm, 1,83±0,20 g; dan 9,08±0,81 cm, 2,15±0,26 cm, 4,66±0,88 g, sedangkan sekum kiri dan kanan serta kolon itik bali berumur 5 bulan berturut-turut yaitu 18,45±1,34 cm, 1,09±0,96 cm, 2,16±0,32 g; 17,63±1,32 cm, 1,05±0,05 cm, 2,05±0,42 g; dan 10,33±1,50 cm, 2,21±0,23cm, 5,25±0,38 g. Dari hasil penelitian dapat disimpulkan bahwa struktur anatomi dan histologi pada fase umur starter, grower, dan finisher adalah sama, tetapi dalam pengamatan morfometri dapat disimpulkan bahwa perbedaan umur memengaruhi peningkatan morfometri anatomi usus besar itik bali.
