winter, nutrients, feed
Calves have been raised successfully in hutches at South Dakota State University since the 1950s. Calf losses averaged 6 to 8% compared to the nearly 20% losses experienced by many dairy producers. However, calves in hutches need more nutrients during cold weather. The calf at greatest risk to be lost is one that was weaned just before severe weather occurs. This calf may be consuming enough feed to maintain itself under normal conditions but not enough to meet the extra requirements needed under severe weather conditions.
