Estimating withdrawal period after topical application of oxytetracycline for digital dermatitis treatment
Digital dermatitis (DD) is a polybacterial disease that affects the skin on the heels of cattle. Round lesions occur along the coronary band of the claws, above the interdigital space next to the heel bulbs. It was first described in Italy in 1974 by Cheli and Morterallo, and it has become a growing problem worldwide for the dairy industry.
Clinical endometritis is defined as purulent or mucopurulent uterine discharge present in the vagina after 21 days postpartum, and it is associated with tissue damage, delayed uterine involution, disruption of endometrial function, and perturbation of ovarian cycles.
Subclinical ketosis is characterized by elevated levels of ketone bodies in blood, and it is one of the most common metabolic disorders in dairy cows during early lactation. Cows with ketosis reduce their dry matter intake and are more prone to develop other diseases such as metritis, and displacement of abomasum.
Monitoring and optimizing udder health of dairy cows is vital for increasing dairy milk production, sustainability, and economic efficiency. A recent study from Ghent University’s Faculty of Veterinary Medicine analyzed intramammary infections during the dry period using somatic cell count (SCC) data.
