      Abstract
      Corticosteroid is an anti-inflammatory agent which have been used for poultry industry widely. The aim of this research was to study the effect of corticosteroid on lymphoid organ of broiler by histopathological analysis. Thirty commercial DOC (Day Old Chick) were divided into 2 groups. First group was control and second group was treated by corticosteroid (3 mg/Kg) orally. Each group was divided into 5 subgroups according to their sacrifice day at age from 2 week until 6 week. This treatment done for 6 weeks, broilers then were necropsied. The bursa of Fabricius, thymus, and spleen were collected as histopathological samples. Samples were processed routinely to prepared histopathology slide stained with Haematoxylin Eosin. The parameters observed include to measured the number of lymphoid follicle of bursa Fabricius and spleen, the number of lymphocyte of bursa, thymus and spleen, and width of bursa’s plica and cortex and medulla of thymus. Quantitative data were analyzed with T-student test. The observation results was corticosteroid caused immunossupression that showed by decrease of lymphocyte and lymphoid follicle numbers which are significant (p<0.05) compared to the control group. There were significant (p<0.05) compare to the control group on the number of small and large lymphoid follicles, high and wide of plica of bursa of Fabricius, width of medulla of thymus, and the number of lymphoid follicles of spleen.
       
      Kortikosteroid merupakan senyawa anti-inflamasi yang digunakan secara luas khususnya dalam dunia peternakan. Tujuan dari penelitian ini adalah mempelajari efek kortikosteroid yaitu Prednisone pada organ limfoid ayam broiler. Sebanyak 30 ekor DOC dibagi menjadi 2 kelompok. Kelompok pertama adalah kontrol dan kelompok kedua adalah perlakuan (diberikan Prednisone 3 mg/kg BB per oral). Masing-masing kelompok dibagi menjadi 5 kelompok sesuai umur perlakuan, mulai dari umur 2 minggu sampai 6 minggu. Perlakuan ini berlangsung selama 6 minggu setelah itu ayam dinekropsi. Organ limfoid yang disampling adalah bursa Fabricius, timus, dan limpa yang selanjutnya dibuat preparat histopatologi menggunakan pewarnaan Haematoxylin Eosin dan diamati. Parameter yang diamati antara lain, jumlah limfosit, jumlah folikel limfoid, tinggi dan lebar plika bursa Fabricius, jumlah limfosit dan luas organ timus, serta jumlah limfosit dan folikel limfoid pada limpa. Data dianalisis secara kuantitatif dengan uji lanjut Tstudent. Hasil dari penelitian ini adalah kortikosteroid memberikan efek imunosupresi yang ditunjukkan menurunnya jumlah limfosit dan jumlah folikel limfoid organ limpa. Jumlah limfosit Bursa Fabricius, timus, dan limpa menunjukkan hasil yang berbeda nyata (P<0.05). Jumlah folikel limfoid besar dan kecil, tinggi dan lebar plika bursa Fabricius, luas medulla timus, dan jumlah folikel limfoid limpa menunjukkan hasil berbeda nyata (P<0.05). Kortikosteroid memberikan efek yang signifikan terhadap organ limfoid ayam broiler.
