Young Stock Generally, the pre-weaning period is the most critical time of an animals’ life, usually expensive due to the high costs of milk and high quality concentrates. Calves require a lot of attention during this period. After weaning, rearing gets less critical, but calves should to no account be neglected. To allow animals to…
To make comparison possible, animals are converted to the same unit. This is called Livestock Unit (LU). One LU denotes the feed requirement of a standard animal of a certain live weight (usually 550 kg). With LU it is possible to compare feed needs for sheep, goats, calves and other animals with those of dairy…
