“…There was a difference in group 1 and 3 and no difference in group 2 comparing the results of each group on D-70 with D14, which shows that the dry period can decrease the degree of HK, but in some cases are irreversible, according to the injury level in the teat (19). The higher the HK score, the lower the mechanical barrier and the higher the ease of teat contamination, consequent incidence of subclinical mastitis (19,40,41) .…”

The aim of this study was to evaluate the use of antibiotics in cows during the dry period. The survey was performed on 148 teats during the dry period, with sample collection in the period D-70 (70 days before delivery) and D14 (14 days after delivery). The milk samples were collected for the Strip Cup Test (SCT), California Mastitis Test (CMT), Microbiological Culture, Somatic Cell Count (SCC), Somatic Cell Score (SCS) and Hyperkeratosis (HK). The groups in which there were no microorganisms grow were divided into two groups, in the first group only the internal sealant in the teat was used (Group 1) and there was another group with the intramammary antibiotic use associated with the internal sealant (Group 2). Teats which were considered positive, with microbiological growth, were treated with the intramammary antibiotic associated with the internal sealant (Group 3). In the comparison of the results of the CMT test between D-70 and D14, a statistical difference was observed in Groups 2 and 3. Group 3, which comprises the positive teats in D-70 presented a reduction of 83.87% and 32.26% in the CMT test between D-70 and D14. Regarding HK, group 1 and 2 had a statistical difference in relation to group 3 in D-70 and D14. As for the numbers of bacteria isolated in D-70 and D14, there was no difference comparing Group 1 and Group 2, unlike Group 3, which had a difference. Group 1 and Group 2 were all negative teats in D-70, showing that the intramammary antibiotic did not influence the outcome of D14. In group 3 there was a reduction of isolates from 62 to 15 in D14. The most prevalent microorganism was Streptococcus agalactiae with 43.37% of the total isolates, followed by Staphylococcus aureus (16.87%) and Corynebacterium spp. (13.25%) and Coagulase negative Staphylococcus (SCN) (10.84%). The selective treatment of teats in dry dairy cows has advantages over Blanket Dry Cow Therapy by reducing the indiscriminate use of antibiotics, avoiding bacterial resistance, ensuring better milk quality and greater food safety. Antibiotics should only be used for teats with subclinical mastitis, with the microbiological culture at the end of lactation performed by fourth individual mammary.

Efficacy of novel antiseptic product containing essential oil of Lippia origanoides to reduce intramammary infections in cows

et al. 2020

Background and Aim: The use of antimicrobials in the control of mastitis is of concern in public health due to their inefficiency in targeting microorganisms. Studies with medicinal plants have risen as an alternative to the use of conventional products. The objective of this study was to evaluate the efficacy of an experimental disinfectant based on the essential oil (EO) from Lippia origanoides in preventing the development of new intramammary infections (IMI) in Holstein cows. Materials and Methods: The conventional protocol of pre- and post-milking was used and the control (Conventional treatment [CNV]) and experimental (Experimental treatment [PEX]) products containing EO at 120 μL/mL were applied by immersion. Individual milk samples were analyzed using sheep blood agar methodologies and biochemical tests. The efficiency of the treatment was defined by the presence or absence of Staphylococcus aureus, coagulase-negative Staphylococcus, and Streptococcus spp. Results: There were no clinical and subclinical mastitis cases, no lesions in the mucosal of teats, nor dirt score between groups in this study. Both treatments did not influence the occurrence of IMI. Conclusion: The results revealed that PEX acts efficiently against microorganisms compared to the disinfection by the conventional product demonstrating the efficacy of the alternative product on the prevention of new IMIs in dairy cows.

Formation and development of the veterinary pharmacy and veterinary drugs market in Ukraine is an urgent issue. In order to prevent infection of the mammary gland in cows after milking, the nipples are treated with a suitable disinfectant for complete immersion or spraying. However, the agents for the prevention of mastitis, presented in the Ukrainian market, are expensive and there is a need to develop domestic veterinary preparations of different forms of release. This work is a continuation of research on the development of the composition and technology of a means for antiseptic treatment of nipples and udders of cattle, in the form of a spray, in order to prevent microbial contamination and prevent mastitis. To obtain a stable veterinary drug based on citrate of silver and copper, the dissolution regimes of the substances were investigated, the order of introduction of the active ingredients and auxiliary substances into the solution, the duration and the rate of stirring during dissolution. It is established that the most optimal are the following technological modes of spray preparation: dissolution temperature 20-220С, mixing time from 10 to 15 minutes, with stirring intensity from 150-200 sec-1. The selected technological regime ensures the stability of the veterinary drug "Argocide-copper" during storage for 12 months. The technology of obtaining a spray in the conditions of industrial production of veterinary preparations of LLC "Brovafarm" (Brovary, Ukraine) is developed. Critical stages and critical control points in the production process of a veterinary preparation of antiseptic action are determined.
