Prenatal Calf Nutrition The mother's nutrition during the dry period will affect the calf. Vet Clin North Am Food Anim Pract. Waste milk from antibiotic treated cows as feed for young calves. Equations used to compute net energy and protein requirements for growth were evaluated with data from studies of body composition changes in Holstein heifers; this model accounted for 96% of the variation in energy retained with a 4% bias. Quality blood proteins have been shown to perform as well as milk protein. Also, dip navels in iodine solution 7% tincture as soon as possible.

The importance of the mother's first colostrum soon after calving and mothering by the dam is emphasized. To simulate natural calving conditions for intensively managed dairy cows they should be moved to maternity accommodation prior to the onset of calving though studies comparing this with moving once calving has commenced have not been published. An emphasis on prevention is critical, limiting the need for subsequent intervention, particularly with the management of diseases of the gastrointestinal and respiratory systems. Calving supervision Good calving supervision involves being present to assist during stage two of calving or to call for veterinary assistance, if required but not intervening unnecessarily.

Proteins derived from milk sources, such as whey protein isolate, delactosed whey, dried skim milk, and casein, are generally excellent sources of protein, but the quality of even these protein sources may be affected by processing methods. Other animal proteins such as plasma proteins also may be of good quality. Waste milk is an economical and nutritious source of liquid feed for young dairy calves if handled properly. Rations supplying similar amounts of metabolizable energy from varying proportions of milk:concentrate resulted in comparable live-weight gains.
