Heifers

A study at the Central Maryland Research and Education Center examined the impact of grazing management on pregnant dairy heifers. A total of 166 Holstein heifers were split into two groups: one group received a total mixed ration (TMR), while the other was rotationally grazed on various pastures. Initial results showed that although final body weight and hip height were similar, TMR-fed heifers had better body condition scores and average daily gains. Grazed heifers experienced initial weight loss during an adaptation period and took longer to regain their weight. Long-term performance will be evaluated during their first lactation to assess effects on milk production and health. This page will be updated annually with the results.
