Six 3-way Norwegian Red (NRF) crosses in the U.S., plus one NRFxHolstein

(Working on it...YouTube messed up proportions) Iowa dairy producer &veterinarian, Dr. Dave Duitscher, milks 1,000 cows; 60% are crossbreds & 40% are straight Holsteins. His favorite 3-way cross is Norwegian Red x Jersey x Holstein because "they milk really well, they have really good health traits &their reproduction is excellent." (6 of the 7 cows are 3-way crosses of Norwegian Red x Holsteins x Jersey). With crossbreds we have "cows we really don't have to mess with a lot." (Cows in picture average 55 days in milk.)
