Offspring 1988
This Holsteiner stallion showed very sturdy, almost excessively developed foals. The group of picked foals were only of moderate riding type, some were actually less so. The group of selected foals showed a lot more refinement and quality, they were also more than sufficient in the riding type in regards to build. The head is sufficiently expressive, often with a very nice eye. The neck has good length but often comes from deep in the chest. The wither was only moderately developed among the picked foals but was better among the selected foals. The wither-shoulder connection should be smoother. The shoulder has sufficient length but should often have more slope; this is especially true for the picked foals. Back and loin formation are sufficient. Even though among the picked foals it was a little flat, the croup was generally sufficiently formed with sufficient length. The foreleg is generally correct, some are a little straight. Several foals are toed out and this also shows during movement. He hindleg was clearly better among the selected foals than the picked foals, where they were long and sickle-hocked. The picked foals had legs of only moderate quality but the selected foals were better. The walk is sufficient in scope but shows little elasticity in the pastern. The trot varies. Some foals trot with power and cadence, showing a lot of scope and there are those that move with little use of the back and little bend in the hock. In general it was noticed that the foals did not jump into the canter when going fast. The stallion clearly needs mares with Thoroughbred blood.
The veterinary remarks are in regards to hocks and pasterns that can be rather lean.
In short: very sturdy, sometimes excessively developed foals that vary in regards to type. The trot also varies, both in regard to scope and power.
Shown: 41 foals out of 194 breedings.
Keur 1995
This stallion received the keur predicate both because of his performance and conformation heritability. With 133 points (and reliability of 85%) he is in second place on the jumping index; for dressage he scores 107 points (with 71% reliability). Burggraaf has one approved son, Habsburg. For conformation heritability the stallion scores high for length and muscling of the neck, long sloping shoulder, long sloping croup and good movement. He also scores high in regards to predicates. Of the 156 studbook mares, 78 became ster and 19 are already keur. During the pre-selection of the 94/95 Stallion Show, 8 of his sons were selected for the second round.

Performance 1986
Friendly, honest, obedient, and attentive with pretty good humor. He was green at the beginning of the test. Has trouble collecting and has a very sensitive mouth, therefore he was longed several times. He must be ridden lightly and then he is fun to ride. He lacks elasticity. The walk is big but searching. The trot is sufficiently powerful and big. The canter improved a lot during the test, it has good scope and is strong but heavy. He shows good technique and a lot of ability during jumping. He jumps good at the jump in cross-country even though it is big there is no real cross-country gallop. He is pretty willing to work and looks at the work as normal. He has sufficient talent for dressage, more than sufficient for cross-country and very much talent for jumping. He was fat upon arrival, got less food than normal and lost weight. Afterward he was fed normal rations. He is very quiet in his stall.
He had an hoof infection on 4/28 and received two days stall rest.
On 4/28 he quit the test because his blood test said that Landgraf I could not be his sire. Later it was found that Landgraf I was indeed the sire and Burggraaf resumed his participation of the test on 7/07.
