A calf should con- sume some colostrum within 15 minutes after birth at least 6 pounds within 4 hours, and 12 pounds within 24 hours. A calf should be left with its mother for 24 hours. Also, presence of the dam promotes greater absorption of antibodies, resulting in higher antibody blood levels. A calf's environment is a vital factor in its survival and performance. Air circulation is important, but a draft must not be created over the calf.
Calves produce a lot of moisture so ventilation is needed in winter as well as in summer.
Absorbent bedding should be used, with good drainage underneath. Special attention must be given raised calf stalls to assure that they don't create drafts. Calf hutches can provide separation between calves and natural ven- tilation free of drafts. For housing recommendations refer to plans for individual hutches. Attention Young calves require close supervision.
