NEWS 90 FEED & ADDITIVE MAGAZINE May 2024 NR X Holstein crossbred cows surpass pure Holsteins In a study conducted by Geno at a large US dairy farm with over 15 years of experience in milking crossbred cows, results reveal that Norwegian Red (NR) X Holstein crossbred cows surpass pure Holsteins in various key performance indicators. The study, utilizing raw data collected through Dairy Comp and analysed using SAS (Statistical Analysis System) statistical software, focused on different generations, including over 2,900 Holsteins and more than 5,400 NR X Holstein crosses, spanning F1 to F4 generations. Comparable Milk Yield with Lower Feed Cost Over 10 months (305 days), NR crossbred cows produced an average of 25,052 lbs. or 11,363 kg from all generations compared to 25,155 lbs. or 11,410 kg of milk produced by Holsteins. This parity in milk yield was achieved with a lower feed cost for NR crosses. Increased Income from Shorter Days Open NR crossbred cows showed a shorter period of days open, with 17 fewer days open compared to Holsteins. This advantage in reproductive efficiency contributed to more milk sold and increased overall income. Higher Milk Solid Yields and Percentages NR crossbred cows outperformed Holsteins in fat percentage, with an average of 4.25% across all crossbred generations compared to Holsteins' 3.73%. These higher fat yields add to the overall economic advantage of NR crossbred cows.
