Use and Evaluation of the Smaxtec Internal Monitoring System for Scientific and Industrial Fattening of Kalmyk Cattle in Yakutia and Some Economic Aspects of Fattening

Abstract

The article presents the results of using the SmaXtec internal monitoring system for fattening calmyk calves up to 18 months with the inclusion of local natural feed additives in the diet. For 60 days of fattening, an absolute increase in live weight was obtained from 45 to 55 kg with an average daily increase of 800-900 grams. We studied the monitoring data – the pH level and temperature of the rumen, the activity of the animal during the fattening period when changing the feeding diet. Calculated the costs and cost of feed during fattening.
