GAMBARAN HISTOLOGIS BURSA FABRICIUS AYAM KAMPUNG (Gallus gallus domesticus) PADA UMUR BERBEDA

ABSTRAK Penelitian ini bertujuan mengetahui gambaran histologis bursa Fabricius  ayam kampung (Gallus gallus domesticus) pada umur berbeda. Hewan yang digunakan adalah ayam kampung jantan berumur 1 bulan, 2 bulan, dan 3 bulan masing-masing 3 ekor. Bursa Fabricius masing-masing hewan diambil dan diproses secara mikroteknik dengan pewarnaan Hematoksilin-Eosin (HE), kemudian diamati di bawah mikroskop. Hasil penelitian menunjukkan adanya perbedaan struktur bursa Fabricius dari ketiga umur ayam kampung tersebut. Folikel bursa Fabricius pada ayam kampung umur 3 bulan berbentuk panjang, jaringan limfoid tampak lebih padat dibandingkan ayam kampung umur 1 bulan dan 2 bulan. Bagian korteks pada ayam umur 3 bulan tampak lebih tebal dan bagian medula lebih panjang, pada umur 2 bulan lapisan korteks terlihat tipis dan daerah medula terlihat lebih pendek, sedangkan pada umur 1 bulan lapisan korteks tampak semakin tipis dan daerah medula tampak semakin pendek. Kesimpulan dari penelitian ini adalah semakin bertambah umur ayam kampung maka semakin panjang folikel bursa Fabricius, sedangkan jumlah folikel semakin berkurang.

Animal used were local chicken age 1 month, 2 months and 3 month s, three chicken each . Bursa of F abr ic ius tissue of each chicken were taken and processed in m icrotechni que with H ematoxylin- E osin (HE) stain, and then observed under microscope. Th is results showed there were differences in bursa of Fabricius structure
