The polled gene is becoming more and more common within the Holstein population. Within the dual purpose/MRIJ breed there has seldom been a bull who passes on the hornless gene. Don Quichot (Pp) (Landschot x Tokyo x Jeroen) who is bred in Germany is a dual purpose bull with a large percentage of MRIJ in his blood type and who is also in possession of the hornless gene.
The 100% MRIJ bull Landschot 3249, the sire of Don Quichot, is a bull with an all-round inheritance pattern. This Diman- son scores neutral for milk and protein levels and around average for cell count and fertility. The average sized Landschot 3249 daughters manage to survive quite well given their good scores for longevity This is thanks to the solid udders and sound feet & legs (somewhat more crocked than average) of his daughters who also have good persistency and late maturity.
The polled gene of Don Quichot comes from his maternal line, more specifically from his dams’ sire Tokyo. This cow family can be described as being particularly protein rich. The first 4 generations of cows in the maternal line of Don Quichot only produced milk with an average of more than 3,55% protein. In addition, the fat percentage is high and milk production is at an exceptional level. The conformation of the cows from this tribe is without a doubt solid, namely Dora P 541 stands out in particular with her beautiful udder (90 points). Unfortunately, grand dam Ramona 3 is not registered, while great grand dam Fiena 472 scored 84 points for overall characteristics.
