When more than 1 : 40 of HI titer was designated as positive, 39 of 61 sera from native chickens were positive (63.9%). In the 27 sera from layer/broiler chikens, on the other hand, 22 of them were positive (81.5%). These results indicated that positive rate in the layer/broiler chikens were considered to be statisticaly higher than those in native chikens (P< 0.01). 0aChikens -- haemagglutination inhibition tests -- Mycoplasma gallisepticum -- java -- Broiler chikens
