Subclinical mastitis in cows: prevalence, causes, and treatments

Abstract

The etiology and pathogen- esis of mastitis in 90 cows of FG "Mriia" of the Rivne area were examined based on the findings of the diagnostic stage of obstetric examination in 2016-2018. Breast irritation was detected in 83.3% of the cows throughout the studyThe disease's onset was influenced by the prevalence of postpartum diseases such postpartum paresis and ketosis. Experiments on the preventative and curative effects of "Forticept" udder hygiene products on mammary gland health, milk quality, and cow output are detailed. Both the antibacterial "Forticept Udder Wash" and the film-forming "Forticept Udder Forte" are used to clean and sterilize the udder before to milking, and to protect the udder nipples thereafter. After 15 days of therapy, the number of animals with subclinical mastitis (SFM) may be drastically reduced (by 55%) by treating the udder of cows before and after milking with the "Forticept" complex. The frequency of SFM in the cows in the experimental group dropped from 41.7% to 19.0-23.0% during 30 days of "Forticept Udder Wash" and "Forticept Udder Forte." No reduction in SFM symptoms was seen despite hygienic treatment of the cows' udders with the medications "Kenopur" and "Kenocidin"; in fact, on day 30 of the trial, the number of positive milk samples in the control group rose by 4.0% (to 54%). Only one additional instance of subclinical mastitis was identified in the experimental group during the course of the 30-day "Forticept" series. For example, "Forticept Udder Wash" and "Forticept Udder Forte" are both 96.0% effective in preventing SFM, but "Kenopur" and "Kenocidin" are only 70.0% effective as preventatives. Milk yields per day rose as the incidence rate went down, as did the proportions of fat, protein, and casein in the milk, and the proportions of SC, KMAFanM1, and microbes. Somatic cell count in the experimental group was 26.7% lower than in the control group at the conclusion of the observation period (339.14 21.22 k/ml). At the same time, the percentage of breast quarters with somatic cell content more than 400 thousand cells/ml of milk dropped in both the experimental and control groups (19.0% and 15.1%, respectively).
