A Comparative Study between the Preventive Use of Tilmicosin Phosphate (pulmotil Premix) and Mycoplasma Hyopneumoniae Vaccination in a Pig Herd with Chronic Respiratory Disease

چکیده
The objective of the study was to compare the effects of a preventive in-feed medication program using tilmicosin (Pulmotil 200 premix, Elanco Animal Health) at 200 ppm with those of a Mycoplasma hyopneumoniae (Mh) vaccination program (Stellamune Mycoplasma, Pfizer Animal Health) in a pig herd with chronic respiratory disease. In total, 208 piglets were randomly allocated to either the medication (P) or the vaccination (V) group. Pigs of the P group received medicated feed during 3 weeks after weaning, and during 2 weeks at the start of the finishing period. The piglets of the V group were vaccinated twice, at 4 and 22 days of age. Both groups were compared by ADG and FCR (major variables) and by a coughing index, pneumonia lesions and serology for Mh (minor variables). No significant differences (P>0.05) were observed between both groups. In this type of herd, the preventive use of tilmicosin had similar beneficial effects compared to Mh vaccination.

BACKGROUND Respiratory illness is traditionally regarded as the disease of the growing pig, and has historically mainly been associated to bacterial infections with focus on Mycoplasma hyopneumoniae and Actinobacillus pleuropneumoniae. These bacteria still are of great importance, but continuously increasing herd sizes have complicated the scenario and the influence of secondary invaders may ha...
