Studi Seroprevalensi Infectious Bronchitis pada Ayam Kampung di Kecamatan Cipunegara, Kabupaten Subang

Abstract

This study was aimed to investigate seroprevalence of infectious bronchitis in native chicken in Cipunegara sub-distric, Subang. Serum samples were collected from 115 native chickens in 5 villages in Cipunegara sub-distric, Subang. The chickens were raised in back yard farm (sector 4) were located arround commercial farm (sector 1 and 2). Antibody titres against infectious bronchitis were measured by haemagglutination inhibition (HI) test. Serological analysis founds antibody against infectious bronchitis in 91% of the samples with geometric mean titre of 2.,81±1.41. This result indicated high exposure of infectious bronchitis virus in native chicken that raise arround commercial farm.

Penelitian ini bertujuan untuk mengetahui seroprevalensi penyakit infectious bronchitis pada ayam kampung di Kecamatan Cipunegara, Kabupaten Subang. Sampel serum diambil dari 115 ekor ayam kampung di lima desa dalam Kecamatan Cipunegara, Kabupaten Subang. Ayam tersebut dipelihara di pekarangan (sektor empat) yang berlokasi di sekitar peternakan komersial (sektor satu dan dua). Titer antibodi terhadap antigen infectious bronchitis diidentifikasi menggunakan uji haemagglutination inhibition (HI). Analisis serologi menunjukkan antibodi terhadap infectious bronchitis sebesar 91% dengan rataan titer 26.81±1.41. Hasil ini mengindikasikan tingginya paparan virus infectious bronchitis pada ayam kampung yang berada di sekitar peternakan komersial.
