Environmental Consideration on Forage Quality

Rearing Replacement Heifers: Birth to Weaning
In replacement rearing, no phase has greater potential for decreasing production costs and increasing profitability than the period prior to weaning.
The Transfer of Passive Immunity to Neonatal Dairy Calves
A healthy calf crop provides replacement animals for the future of the dairy operation. However, a busy work environment often causes the neonatal calf to become overlooked, leading to consequences that may be irreversible. It is important to understand that the neonate must consume sufficient colostrum as soon after birth as possible to achieve the needed passive immunity to survive the first few weeks of life.
