Abstract

Metritis as one of the substantial disorder is one of the major diseases in dairy farm. The purpose of this study was to evaluate the detrimental effects of METRITIS on a dairy farm complex in Guilan province. Data from years 2000 to 2004 was analyzed using logistic regression procedure. In this research, rate of METRITIS during the study period was 19.99%. Results indicated that year and herd significantly affected the incidence of METRITIS (P<0.01). This rate was highest in year 2002 and for the herd of number 1. The sex and season had not significant effects on the incidence of METRITIS (P>0.05). Also METRITIS had a significant effect on mean MILK YIELD by five months after parturition (P<0.01). The average MILK YIELD in DAIRY COWs that affected by METRITIS and cows without METRITIS were 20.73 and 21.76 kg, respectively. Furthermore, METRITIS had a significant effect on some of the reproductive parameters (P<0.01) and the average of days open in the cows with METRITIS was 17.82 day greater than the cows without METRITIS. Also, the average of interval from calving to first insemination was 6.33 days greater than cows without METRITIS. METRITIS had not significant effect on services per conception (P>0.05). It is concluded that effects of herd and year on METRITIS and effects of METRITIS on mean MILK YIELD and days open were effective.
