Appeasing Pheromones against Bovine Respiratory Complex and Modulation of Immune Transcript Expressions

Bovine respiratory disease is still a major concern and has economic impact. Another consequence of infections the use antimicrobial molecules to control bacterial pathogens. This can participate in emergence shedding resistance that threaten animal as well human health. Appeasing pheromones with their capacity reduce stress thus ability preserve functions immune system have been proposed substances. In this study, we assessed effect appeasing pheromone administration on bovine health performance during fattening period. Zootechnical parameters whole blood transcript expressions were measured over four weeks bulls determine pheromone. We observed increased clinical signs Day 8 (D8) decreased D30 who received higher expression interleukin transcripts group than D8. Our results are overall line previous reports livestock species. Further studies needed shed more light decipher exact mechanisms action.
