Donnerhall's season as a nine-year old ended with a proud tally of successes in 1990 with 33 wins in difficult dressage competitions. In addition to that, Donnerhall gradually distinguished himself more and more as a sire.

One son was sold at the PSI auction, organised by Paul Schockemöhle and Ulrich Kasselmann, Donnerhall progeny also appear from time to time at the Vechta Foal Ring (Fohlenring). Donnerschlag who was bred in Hemmoor by Günther Pape out of the Pik Bube sister Pirola became a I-e premium stallion and absolved his stallion performance test in fourth place.

A breeding bulls eye, as it proved to be later on. A permanent success for the St. Ludwig studfarm. The Rhineland is one of the first breeding regions outside of Oldenburg that profited from Donnerhall's prepotency thanks to Donnerschlag and his sons. Even the breeders in the bordering Netherlands craned their necks. Donnerschlag and his son Dream of Heidelberg have belonged to the most popular sires of West Germany for years.

In the year 1992 however, things really got started. Donnerschwee (breeder: Dr. Jobst Hartmann, Itzehoe) became the top horse of the spring auction. DM 220.000 was the price paid for the son of the best of the 1986 age class at the Federal Mare Show, Weltwunder by Freiherr. No other horse achieved such a price before at a German Breeding Association auction. Donnerschwee was the most successful approved stallion at the 1993 federal dressage horse championship. He has meanwhile won advanced dressage competitions and is now competing in Grand Prix tournaments.

The 1992 federal championships in Verden have gone into the annals of sports history as the "Donnerhall Festival". Primavera whose dam is by Pik König, came third in the three-year old championship. She succeeded in the rare feat of first winning the Riding Horse Championship at the "Rastede Schloßpark" and then being proclaimed champion Oldenburg mare.

Even more apparent was the dominance at the four-year old championships: Here the winner was the Hanoverian Davignon, second the Oldenburg mare "Deutsche Einheit". Otto Schulte-Frohlinde had presented this daughter of the mare Pik Stahl as a present to the three-day eventing team that had won the gold medal at the Olympic Games in Seoul, South Korea. Every Olympic winner was given a foal as a present, even the showjumper team,. The latter's filly, a sister of Don Primero landed at the Paul Schockemöhle stables, where the Donnerhall mare was mated with Classiker. The result: Capuccino, an approved stallion, who changed owners for a high sum at the PSI auction. No-one however profited as much from the horse gift as the Buschreiters. The vice champion mare "Deutsche Einheit" was auctioned in Vechta on the third of October for DM 420.000, bought by the Dutchman Adrie Gordijn . That was a sensation in Germany and it was believed that it would be a long time until this spectacular auction sum would be equalled. When the sum was finally surpassed by the Hanoveranians in Verden in 1996 with the price of DM 450.000, the sire of the prime quality horse was once again Donnerhall. Donnerhall, the Oldenburger is accredited for Hanoverian broodmares and wherever he is involved, good results are more than likely- even with the neighbours.

Adrie Gordijn beams radiantly and simply says the mare which henceforth is named "Donne" was a present. Under this name she became the best up and coming dressage horse of her age class in the Netherlands and today has already had successes at Prix St. George level. Sven Günther Rothenberger and his wife Gonnelien are promoting the sovereign mare with her strong nerves - one of the most noble of Donnerhall daughters. Her colleague in Verden, the champion mare Primavera took a different route. She is fully involved in breeding and is enjoying the pastures of Hemmoor. An imposing figure. Whoever sees her galloping over the green, whoever becomes witness to her seemingly galloping from out of nowhere with a powerful trot, striding along in metres, will most certainly stop and stare in amazement. She is already the mother of a stallion.

In 1993 Donnerhall once again presented the champion mare at the "Rastede Schloßpark". Hallo, and again Pik Bube was the damsire. The combination à la Grönwohld developed more or less by coincidence because breeding considerations tend to predominate. This blood combination has proven to be particularly successful. Many German breeding regions have meanwhile profited from it. Hallo has got a full-sister named High Noon. One of the first horses that made public Donnerhall's qualities as a hereditary transmitter. Trained as a young horse on the Grönwohldhof, she qualified for the German Dressage Horse Championships in Munich and Verden. In Verden Julia Westphal rode the mare, which is owned by her and attained fourth place in the championship. Meanwhile High Noon has been able to establish herself in Grand Prix sport. She is the spitting image of her sire. The silhouettes of the two are especially alike in the lessons of highest collection. Ridden by Herbert Boger, the mare managed to attain many international placements in 1998. For some time now, Donnerhall has belonged to those stallions at the Vechta Elite Auctions who are represented by their own group of progeny.

The combination of Donnerhall with Weltwunder (by Freiherr-Adrian) was a particularly lucrative mating. After the aforementioned premium stallion Donnerschwee, the horses Deutscher Orden, Dr. Lobo, DJ Lobo as well as the Davignon son Dayton came under Uwe Heckmann's auction hammer with the total proceeds amounting to more than half a million Deutschmarks.
