Efficacy of Linco-Spectin water medication on Mycoplasma synoviae Airsacculitis in broilers

Three trials were conducted to evaluate the efficacy of Linco-Spectin (LS) water medication on Mycoplasma synoviae (MS) air-sacculitis in broilers under controlled experimental conditions. Day-old chicks were vaccinated against infectious bronchitis and Newcastle disease virus and exposed to a broth culture of MS by the respiratory route. In each trial, one-half of the flock was treated with 2 g of LS per gallon of drinking water for the first five days of life, and the other half was kept as a control. At two and eight weeks postinoculation (PI) birds were weighted individually and examined serologically, culturally, and grossly for MS airsacculitis. Linco-Spectin water medication was effective in controlling MS airsacculitis in broilers.
