Wireless measurement of digestion of cows

Introduction

IQRF technology has been successfully used in the study "The effect of individuality of animal on diurnal pattern of pH and redox potential in the rumen of dry cows" made by Department of Animal Nutrition and Quality of Livestock Products in Pohořelice, Agri-research Rapotín Ltd., Pohořelice, Czech Republic

The aim of this study was to continuously monitor ruminal pH and redox potential of individual cows using a newly developed wireless device.

Solution

The probe carried out measurements every 20 seconds and average values were calculated in 1 mins intervals.

Three Holstein cows fitted with rumen cannulas were individually tested for ruminal pH and redox potential (Eh) using a newly developed wireless device. The experiment was carried out in the period of 14 days consisting of a 10-day preliminary period followed by a 4-day measurement period. Cows were fed twice daily the diet based on maize silage, and lucerne hay. During the measurement period, ruminal pH and redox potential were monitored continuously using a developed wireless probe.

Conclusion

The study confirmed the appropriateness of the use of wireless data transmission technology using IQRF in the vivo method. This method may be useful for investigating factors affecting the dynamics of ruminal fermentation and may also help in the identification of variables associated with various metabolic disorders. A technique for the measurement of ruminal pH and redox potential using a newly developed device with wireless data transmission presented in this study enables long-term continuous 24-h measurement directly inside the rumen under strictly anaerobic conditions. This method may be useful for investigating factors affecting the dynamics of ruminal fermentation and may also help in the identification of variables associated with various metabolic disorders.
