Monitoring rumen environment in finishing Lidia bulls
Journal Title: Revista MVZ Cordoba - Year 2016, Vol 21, Issue 2
Abstract
Objective. The aim of this work was to characterize the changes in rumen pH and temperature in finishing Lidia breed bulls reared on pasture and fed a total mixed ration (TMR). Materials and methods. Five 4-year-old Lidia bulls received approximately 10 kg of the TMR per animal and day in the morning. Bulls could move freely in a 17-ha fenced area and express normally their feeding behaviour. Internal wireless boluses were used to collect pH and temperature values every 10 minutes throughout the measurement period. Results. Average daily pH was 6.2. Average and maximum daily temperatures were not high enough to be indicative of disease (infections of other pathologies). Conclusions. When rations and feeding systems are appropriately managed, Lidia bulls can be supplemented with concentrates in the finishing stages of their productive cycle without impairing the rumen environment.
