Feeding calves individually is most commonly recommended. It is easier to see the signs of sickness on a calf, and there is no competition amongst the animals for feed. It also reduces the chance of spreading disease, as there is no nose–to–nose contact.
Although one of the challenges of feeding twice daily is the increased labour, you are at an advantage by knowing right away if a calf didn’t drink or could be sick. it is also easier to access the animals to take their temperature to determine if they have a fever. Individual feeding is by far more labour intensive but morbidity and mortality rates amongst the calves are lower compared to other feeding methods.
