LACTATING DAIRY COWS TRANSITIONING TO BRASSICAS
The first two weeks:
- A full rumen is required before lactating dairy cows are shifted onto crops. Fill up with pasture and/or baleage, silage, hay and/or straw after milking. Once all cows have consumed pasture/supplements THEN start cows onto brassica crop
- Start by grazing the crop for no more than 1-2 hours per day during the first few days, returning cows to a diet of pasture plus high fibre supplementary feeds
- During the transitioning period, ensure plenty of long-stem fibre supplements (baleage, silage, hay and/or straw) are available to cows when off crop
- Pasture plus brassica crop is a suitable complete diet for cows once fully transitioned onto brassica. Feed extra supplementary fibre during the transition period
- During transitioning, increase feed allocation of brassica crops in small 15-20% increments every two days, building up to a maximum allowance over at least 10-14 days
- Once feed transition is complete, offer no more than 35% of the diet as crop for lactating cows, due to risk of brassica milk taint
