Done the other way round here, keep highs on TMR and get them back into calf and performing well at peak,
put Low yielders onto Zero Grazing, gives them an extra boost and no meal needed.
we found Fertility is very hard to control on Zero grazed cows no matter how much the grass was managed
OK. Will pass the message on to the boss
Only comment I will make is that the Highs will stay on TMR for morning feed and topped up with fresh grass PM so we can reduce parlour cake down to 16%
