A block designed for short-term use, starting two weeks before calving. Olsson’s Herd Health Pre-Calving is formulated to support the cow’s transition by providing energy and key minerals, including magnesium, which plays a role in muscle function during calving. This block is intended to complement Herd Health 365, helping to optimise mineral utilisation. Adequate energy and mineral intake during this period can support both cow and calf health, assisting with survival rates and early lactation.
