Drying off is a critical phase in the seasonal cycle of each dairy cow. Cows rebuild the mammary tissue required for milk production in the next season. And build up their natural immunity. Plan for sufficient time to allow these processes to take place.
To ensure good energy utilisation around calving and early lactation it is important that feed levels are rapidly increased back to lactation levels during this period. This is the time to increase calcium, magnesium and (depending on diet) phosphorus, to levels adequate to supply 75% of the lactation demand.
These should be strictly fed in acidic forms only. This will ensure the parathyroid gland remains primed to produce the hormone required to utilise calcium, vitamin D, and phosphorous in post calving.
