Two full brothers from the Dutch/Flemish breeding program - Delta Flagstone (Topstone x Relevant) and Delta Dolmen - have created waves with their unprecedented production figures. Based on the Dutch/Flemish merit index both bulls pass on around 2000 kg of milk with +0.30% fat and about +0.10% protein, resulting in 598 and 628 Inet scores respectively. They combine this with high longevity, functional conformation and positive health traits. Unfortunately, Flagstone and Dolmen are not yet available.
But, the popular Delta Endless Rf (Jacuzzi x Finder) is available. He maintains his high production breeding value (based on the Dutch index) of 1155 kg of milk with +0.73% fat and +0.19% protein and 516 Inet, and high feed efficiency (107) which results in a score of +15% CRV Efficiency. Endless is also one of the highest ranked bulls for health traits with a score of +9% CRV Health. This is a logical score as it takes healthy cows to produce milk efficiently. With 109 for maternal calving ease, this Jacuzzi son is also very suitable for use on heifers.
