Abstract: In a pig farm with manifestations of ileitis and dysentery, the methaphylactic efficacy of “Tilmovet 20% - premix” (“Biovet” - Peshtera) having the active substance tilmicosin phosphate - 200 g/1 kg is tested. A batch of 30-day-weaned pigs with an average live weight of 8.1 kg was divided into two groups of 380 pigs. The trial group received feed supplemented with Tilmovet 20% - premix at a dosage of 1 kg/t of feed during the first 10 days from weaning, and the control group only a feed ration. The clinical status of the pigs was monitored and cases of diseased, dead and slaughtered by necessity were recorded for 65 days. Pathological and bacteriological tests were performed to determine the diagnosis, respectively the reason for their failure. It was found that the methaphylactic course with Tilmovet 20% - premix given at a dosage of 1 kg/t of feed for 10 days against ileitis and dysentery in grower pigs, eliminates the clinical manifestation of both diseases and mitigates the manifestations of PCVD, and it was reported: - less affected by ileitis and dysentery - by 2.4%; - less died of both diseases - by 1.1% and less pigs slaughtered by necessity - by 1.32%, in compared to the control group. The treated with Tilmovet 20% - premix grower pigs achieved a 49 g higher average daily gain, respectively, with 3.2 kg of pig more gain growth than those obtained in the control group, and 2.1% more animals transferred to the fattening group, which determined the methaphylactic efficacy of the premix as very good.
