Postpartum reproductive problems in dairy cattle are the leading factors causing infertility and serious
economic losses. The first aim of the dairy cattle management is to maintain a healthy puerperal period
and to have the cow cyclic again at the optimal time and achieve pregnancy. This is the first requisite for
a desired reproductive efficiency level. Puerperal endometritis is a serious cause of repeat breeder, acyclic
and anoestrous cows, thus, deteriorating reproductive efficiency. Studies have shown that, puerperal
endometritis rate in dairy cattle farms is between 10-80 %. Puerperal endometritis causes the postpartum
luteal activity to longen , delays cyclic activity, the first oestrus and the first insemination after delivery
and pregnancy. The principal of the therapy for the puerperal endometritis is to fasten the involution and
clean up the infection. For this: -Antibiotics-Antiseptics-Hormones are used widely. In this study, a more
practical administration was tried to be added to the treatment procedures of puerperal uterine infections.
These treatment procedures include administration of iodine to the uterus 1 or 2 times depending upon the
severity of the case and then synchronization by Doublesynch protocol. According to these treatment
protocols every administration is given with 5 days intervals and the Doublesynch is started with a further
5 days interval. In order to minimize the time loss thanks to these intervals between treatments, the
Doublesynch protocol is combined with the last iodine solution. This new administration route is then
called the Lugovsynch protocol.
