Reduced sanitary quality of milk in patients with metrite cows after childbirth

Abstract

t has been established that the development of purulent-catharal inflammation of the former gravid horn of the uterus in cows after delivery as a result of abortion, dystocia, stillbirth, caesarean section, uterine dislocation or seedlings is accompanied by an increased microbial and fungal background of the uterus, in their symbiotic relationships. In cows without delivery during childbirth, only from the 5... 9th day after calving in 35.37% cows, the genitals were contaminated with various non-pathogenic microflora. In cows given maternity care, already on the 3rd day after calving, bacteria were isolated, which in 74.5% of cases were contaminated with pathogenic microflora S. aureus in 15.5% of cases, E. coli in 37%, K. pneumonia - 12% and S. pyogenes in 10% of cases. The results of mycological studies revealed that A. fumigatus, C. albicans and C. crusei were isolated from cows as a result of childbirth. It was found that in cows with purulent-catharal inflammation of the uterus in the milk of sick cows, a significant change, with a high degree of correlation, is: the content of somatic cells (CK) r = 0.63, lactoperoxidase (LPO) r = 0.65 and lactoferin (LF) r = 0.66. Milk obtained from patients with purulent-catharal inflammation of the former gravid horn of the uterus showed 2 times the total bacterial insemination than milk obtained from clinically healthy animals. At the same time it has a reduced number of lactic acid organisms after the first days of storage. Acid formation occurs faster by 5.0-15.0% than in control samples of milk prepared to produce lactic acid products. Acidity in Lactobacillus bulgarus-fermented milk was 12.0-13.3% higher than in starter control samples, and the viability of symbiotic coupling cells was an order of magnitude lower (2.5x106 vs. 2.5x107) compared to lactic acid control samples.
