Does anyone have any ideas on how to stop calves cross suckling? Rearing channel island breed calves in group hutches (as required by milk buyer) on milk bar teats. Calves fed mothers milk for first 4 days on bottle then transition onto feeder with milk powder. I’m feeding 3.5L morning and night mixed at 150g/L. Straw and nuts ab lib. Experiencing cross suckling in calves and right through to calving down. Causing major cell count and mastitis issues once calved down.
