Abstract :  The aim of this study was to examine the effect of the prepartal administration of the monensin release capsule on dry matter intake insert ignore into journalissuearticles values(DMI);, milk yield, and some reproductive parameters of dairy cows. The cows were divided into study insert ignore into journalissuearticles values(n = 35); and control insert ignore into journalissuearticles values(n = 41); groups. The study group cows were administered the intraruminal-monensin releasing capsules at 21 ± ± 3 days before expected calving and the control group cows were not subjected to treatment. Monthly mean DMI; cumulative milk yield at 30, 45, and 60 days in milk insert ignore into journalissuearticles values(DIM);; peak milk yield; days of 1st AI; days open; and culling rate were measured. Monensin delivery prepartum decreased DMI postpartum insert ignore into journalissuearticles values(P < 0.001); but did not alter cumulative milk yield at 30, 45, and 60 DIM; peak milk yield; days of 1st AI; days open; or culling rate insert ignore into journalissuearticles values(P > 0.05);. In conclusion, monensin-releasing capsule administration in the prepartum period did not affect performance reproductive parameters postpartum. However, it may contribute to the economics of production efficiency.
