Values of pH Rumen Content Depending by Sampling Techniques Impact of Rumenocentesis on the Health of Dairy Cows, by Monitoring of Clinical Status
Abstract
The aim of the study was to assess the difference between the value of pH rumen content depending on sampling techniques (with nasoesophagal-probe and rumenicentesis) and monitoring of clinical status for the health and welfare of cows for milk production affected by rumenocentesis. The difference in the average value of pH rumen content in all samples analyzed was 0.109 pH units increased when the rumen content was sampled with nasoesophagal-probe. The data obtained show that technique of rumenocentesis has an impact on the health of animals. By tracking the overall clinical indicators, in two cows (2/10 or 20%) were observed increase in body temperature to 39.8 ° C values, increasing the density of up to 37 respiratory breathing per minute, increasing performance up to 92 heart beat per minute and hypotony condition, with reduction in the number of rumen contractions to 3 movement for 5 minutes.
Keywords: SARA, ruminal pH, nasoesophagal probe, rumenocentesis, rumen contractions.
