On farm culture system as a tool to reduce the antimicrobial consumption at selective dry cow therapy in Czech farms
The aim of the study was to evaluate the impact of SDCT on the antimicrobial consumption and on the herd SCC, % of high SCC cows, % of high SCC fresh cows and % of chronic infections in consequence with the compliance of the proposed methodology during the 12 month trial. Two selected farms with different type of breeding environment were included into the trial. Both of them have implemented mastitis management based on DHI data analysis and culture diagnostics using on farm culture system (OFC) MicroMastTM at the level of clinical and subclinical mastitis before the start of the study. Blanket dry cow therapy was used. Farm A breed 480 Red Holstein cows with milk yield 11.500 l/lactation in straw bedding barns. Farm B breed 110 Czech fleckfieh cows with milk production 7.100 l/lactation in deep bedding barn. Cow selection strategy was based both on the algorithms and culture based decision (Vaquez et al., 2018). All other cows were cultured using MicroMastTM triplate set (Prasek et al. 2010) to identified high-risk cows. On Farm A were as a low-risk cows were identified 51.7% reduction of antibiotics use. Antibiotic dry cow therapy administrated into all quarters were used in 32.1% cows and in 16.2% cows were used antibiotics in selected quarters. Percentage of high SCC cows increase during 12 months from 11% to 18%. On Farm B were as a low- risk cows were identified 98.2% reduction of antibiotic use. Antibiotic dry cow therapy was used in 1.8% cow during one year study. Percentage of high SCC cows increase from 12% to 15%. We can conclude that the selective dry cow therapy has a potential to reduce the antimicrobial consumption on farms. Our results showed reduction for 51.7% and 98.2% respectively. The successful implementation of the SDCT program is based on proper following of the protocol and proper employee training especially hygiene and technique of antimicrobials and sealants intramammary infusion.
