20 lip 2023 · At dry-off, intramammary antimicrobials are either administered to all cows (blanket dry cow therapy-BDCT) or selectively to cows at high risk for mastitis during the dry period and early post-partum period (selective dry cow therapy-SDCT).
culling cows with chronic mastitis. Curing Existing Infections The most effective time to treat subclinical udder infections is at drying off. Dry cow therapy has the following advantages over lactation therapy: • The cure rate is higher than that achieved by treatment during lactation, particularly for Staphylococcus aureus.
2 wrz 2020 · Associated Data. Supplementary Materials. Data Availability Statement. Go to: Abstract. Lactating cows are routinely treated at dry-off with antibiotic infusions in each quarter for the cure and prevention of pathogenic intramammary infection, which remains the most common disease in dairy herds.
1 mar 2021 · Cows more likely to have a mastitis treatment in early lactation were cows with high mean SCC during the previous lactation, cows with a high milk yield near dry-off, and cows with a high peak milk yield in the previous lactation.
Dry Cow Therapy. On the average, 40-50% of the cows in the herd may have subclinical bacterial infec-tions present in the udder. Milk appears normal but after culturing, mastitis-causing pathogens can be iso-lated from the milk. In a few herds, somatic cell counts may be low. Administer an effective dry cow mastitis
Dry cow treatments are a vital element of mastitis control and must be selected appropriately in order to get the best results. Depending on the herd bulk milk somatic cell count and the individual cow infection status, the most suitable regime for dry cow therapy will vary between herds.
