摘要

Lactating dairy cows were accidently fed monensinat a dose of 32.7 g per ton (36 ppm) of feed for three weeks.This resulted from a mixing error when monensin wasadded to the mineral premix, as well as an error in theamount of mineral fed to the lactating cows. A decreasein dry matter intake was noticed during the first threedays following the mixing error. Bulk-tank milk fat percentage decreased by 0.6, but daily milk production increased by 6.9 1b (3.1 kg)/cow/day during this period, andfor an additional two weeks. A residual effect on milkproduction and fat percentage was observed for threeweeks after monensin intake returned to the prescribeddosage of 14.5 g per ton (16 ppm). This residual effectwas more pronounced during the first week followingresumption of the prescribed intake of monensin.
