Heifers to breeding age: roughage of choice, supplement. Pregnant heifers to calving: nutrition based on housing and delivery system of the farm, roughage, supplement. Feeding dry and lactating dairy cows: nutrition based on feed storage and milking system. Forage selection: feed animals like seniors, want food at the same time every day and they want it simple. Transition cows (-3 to +3 weeks around calving: dry patter intake is reduced, energy reduced (calcium needed for muscle contraction, metabolic disturbances. Displaced abomasum twist in stomach so they sow it to bottom. Feeding the rumen: synchronization of nutrients. Maintain health of the rumen: microbial protein highest correlation with milk proteins. Feeding lactating dairy cattle (mt: three sisters.
