Subacute Rumen Acidosis (SARA) in Cows With Intensive Breeding in Different Periods of the Year

In the period January 2010 - January 2013, in four cattle farms were studied experimentally vulnerability relations of cows from subacute rumen acidosis (SARA condition) in different seasons of the year. Assessment of the presence of SARA condition in cow was based on the evaluation of rumen pH content. In 137 cows studied in different seasons of the year, for a period of 3 years was found various state presence of SARA. More affected animals were found in summer. In this season resulted positive for SARA condition 11 of 37 controlled heads of cattle or 29.7%. Levels and increased vulnerability was found in the spring and winter, respectively, in the spring 4 by 33 heads of cattle controlled, or 12.1% in winter and three heads, or 9.3% of cows controlled resulted affected by SARA condition. In the autumn season had the lowest level of vulnerability of the situation SARA cows. In these seasons were found affected two heads or 5.7% of cows controlled. The largest group of risk animals to be affected by SARA condition belonged to autumn. Among the incidence of the SARA condition in cows and the seasons were found correlative relation and negative character (r = - 629).Keywords: SARA condition, ruminal pH, pH- meter, nasoesophagale probe, season
