Calf feeding - the first six months

摘要

An accelerated calf program requires top-notch management, unique milk replacer and calf starter feeds, and an extra 50 dollar investment in this phase of the calf program. To recover this investment, calves must continue to grow, be bred 30 to 45 days earlier than traditionally raised heifers based on size (not age), and avoid fat heifers. An accelerated calf program is not "right" for everyone, just like TMR or BST does not work for everyone. Consider the accelerated calf approach as a "new" method to achieve genetic growth potential. Some dairy managers report poor results and have abandoned the system. Each producer will need to evaluate how this system works on her or his farm. Feeding heifers from 3 to 6 months of age must maintain optimal growth patterns. Measure heifers at six months of age to insure growth targets are achieved. Holstein heifers should weigh 450-500 pounds, have body condition scores of 2.25, and measure 40 to 42 inches at the withers.
