Caio Abércio da Silva, Edgard Hideaki Hoshi, Juliana Sarubbi

Abstract


The experiment was conducted to evaluate the use of 100 ppm of Tilmicosine antibiotic or 200 ppm and the use of Tiamulin (50 ppm) plus Oxitetracicline Cloridate (150 ppm) to control of respiratories diseases caused mainly by Mycoplasma hyopneumoniae in swines in growing and finishing phases. The experiment used two pigs farms (A and B) with different sanitaries standarts. It was used 945 swines, been 639 animals in farm A and 306 animals in farm B. The experiment evaluated the performance of animals in the growing and finishing phases, the classification (score) of lesions in lungs, and the economic efficiency and the costs of the experimental treatments. There were no difference (P>0.05) between the treatments to the performance and to the lesions scores in lungs for A and B farms. The concentration of 100 ppm of Tilmicosine was efficient and economically viable to the control of mycoplasmal pneumonia.
