The first bolus designed to support calves’ breathing functions


Respibol is the essential nutritional solution for preventing respiratory issues for calves under 6 months. It can be used as soon as 10 days old on calves that were born in a difficult context (recurrent respiratory episodes, insufficient ventilation, high density of animals, transitions, allotments). RESPIBOL can also be used as a complement to vaccinations or for sustaining calves whose respiratory sphere has undergone a veterinary intervention. The goal is to limit any risk of relapse.

Respibol includes trace elements such as copper, zinc, manganese and selenium. This bolus contains pulmonary plants and eucalyptus are that act in synergy with these ingredients to support calvesrespiratory system and the good functioning of their mucociliary cleansing.

Mains benefits: 
  • Contribute to calves’ respiratory comfort during challenging phase of life 

  > Change of season

  > Change of housing, batching with other animals

  > Weaning 

  • Support specific respiratory vaccines uptake

  •  Contribute to calves’ growth


Le RESPIBOL se distingue à la fois par sa facilité d'utilisation, surtout sur les veaux allaitants et par ses résultats particulièrement intéressants.

Ce bolus a été testé en particulier sur des veaux de 3 mois d’âge mis en engraissement et soumis à la fois à un stress d’allotement et de changement d’alimentation (paille + concentré).

Sur ces veaux, on peut observer une amélioration significative de la croissance au cours de cette phase d’adaptation (+ 150 g/j) ainsi qu’une réduction fréquentielle des interventions (antibiotiques et anti-inflammatoires individuels) réalisés après cette transition.
