Lutrell® Pure has exactly this effect and makes the start of lactation easier for the cow. It reduces the milk fat content during the supplementing phase in a dose-dependent manner and leads to lower blood glucose utilization per kilogram of milk. This supports the metabolism at the start of lactation and helps the cow to better overcome the transition period. Lutrell® Pure is fundamentally different from established measures that aim to optimize the dairy cow’s energy supply by increasing the energy intake. Scientific studies prove that a targeted reduction in milk fat through Lutrell® Pure leads to higher blood glucose levels in the first weeks of lactation. If fed prior to calving, the cow also mobilizes less body fat.
Lower body fat mobilization reduces the fatty acid load on the dairy cow’s liver. As a result, the liver will have to store less fat. reducing the risk of fatty liver disease, ketosis and secondary illnesses such as lameness, milk fever, retained placenta or mastitis. The dairy cow responds with a higher milk yield. A further consequence of the increased glucose level in the blood is for a positive effect on fertility traits. For example, progesterone is broken down more slowly, which ultimately causes the animals to start their cycles earlier and creates better conditions for the embryo. As a result, dairy cows can get into calf much earlier.
To sum up, Lutrell® Pure can help to use the cow’s energy reserves more efficiently by temporarily reducing the milk fat in a controlled manner, thus stabilizing the metabolic situation. Subsequently, the dairy cow’s productive lifetime and lifetime yield improve, which also makes milk production more economically sustainable (Fig. 1).
