A genome wide association study on age at first calving using high. by Hyeong, K. -E. ; Iqbal, A.
In summary, heifer nutrition and body condition at first calving is critical for future productivity. We need to target our heifers to calve at a BCS of 5 or 6 for optimum rebreeding. CRYSTALYX® BRAND SUPPLEMENTS can help you achieve this goal with a wide variety of supplements, including the CRYSTALYX® Breed-Up® Supplements (available in 17%, 20% and 28% protein formulas). They are designed for pre-calving through breeding.
