i do the complete opposite to what lads are saying here, cow calves and calf is given 3 ltrs of colostrum from the mother with a bottle and teat while she is licking the calf, cow and calf left together for first day and after that the cow is let into her calf every night for 5 to 7 nights before weaning, haven,t had a case of scour for years and don,t vaccinate . smaller numbers than most lads and a more spread out calving pattern but i think the first week is vital in a calfs life and a bit of time spent then is better than time and money lost for the rest of the animals life
