Bio Holwerda Thiago Twa
Bio Holwerda Thiago Twa was bred at the former Holwerda breeding farm by Nico Hooghiemster in Reduzum (Friesland), which produced foundation stock of the Dutch Friesian dairy breed. The farm was known for its modern FH cows and bulls. Thiago Twa was produced from a very robust dam, Janke 534. She has been transferred to a farm in Drenthe and is producing a good milk yield with high protein ratio. Thiago Twa has style and character. He has perfect legs. We expect excellent results, also from crosses with Holstein cows.
Bio Buitenverwachting Peter
Bio Buitenverwachting Peter was bred by Corneel van Rijn at Buitenverwachting Farm, Hoogmade. He was bred from sire Encore and dam Eva 66 (Kian x Stadel) and thus offers excellent lifetime production with a high milk protein ratio too. The bull also has strong legs and good persistence. The Buitenverwachting herd comprises 40 dairy cows, mainly Holstein and some crosses with Dutch Whiteface and Brown Swiss. Average production is 7000 kg milk per cow, with 4.5% milk fat and 3.65% protein. The herd is predominantly fed quality roughage and concentrates. Antibiotics are used sparingly, if at all.
Bio Bram
Bio Bram is a purebred Meuse-Rhine-Yssel (MRIJ) bull from Den Smitshof breeding farm, Nieuwleusen. His mother is now 16 years old and in her 12th lactation. Her total production so far already exceeds 80,000 kg milk, with an average of 3.89% milkfat and 3.46% protein. Bio Bram was sired by Andre, bred by Karin Godeschalk. She prefers more heavyset MRIJ cows as they have a long productive life and pose few problems. The herd of 55 milk cows has an average age of 7 years. Average production is between 5,500 and 6,000 kg milk per cow. The herd mainly feeds on grass, with little maize. Total concentrates is 1200 kg per cow (including youngstock) and wholeplant silage of wheat and pulses. The farm is not certified organic, but is managed along organic lines. Godeschalk favours homeopathic medication and strictly limits the use of antibiotics (on average one dosis per animal per year), resulting in a healthy and robust herd.
Bio Daxenbichler Doru
Bio Daxenbichler Doru PP is an attractive and robust Fleckvieh bull with a calm nature. He was bought by Mathijs de Haan from Ingen, where he has already produced several daughters about whom De Haan is very content. Doru’s breeder is Anton Daxenbichler from Tuntenhausen (southern Germany), whose breeding goal is productive, persistent animals with a high lifetime yield, that start their working lives slowly but then just keep going and going. Doru’s mother produced an average of 7072 kg milk with 4.03% milk fat and 3.47% protein (average of five lactations). His grandmother Barra calved 9 times and produced an average of 7060 kg milk with 4.45% milk fat and 3.55% protein. Doru’s expected breeding value for persistence is 109. Doru’s calves will be 100% polled, so there is no need for dehorning. Bio Daxenbichler Doru is not suitable for use on heifers.
Bio Proostmeer HenkieBoy
Bio Proostmeer HenkieBoy was an tall bull with a gentle nature. He was a true Holstein type with an triple A code of 342, making him suitable for crossing back Holstein crosses for robust cows and higher milk yields. Bio HenkieBoy inherited these traits from his mother and grandmother. Both cows had a combined yield of 138,000 kg milk with a good composition. HenkieBoy’s mother is a SunnyBoy progeny. This bull is famous worldwide for its all-round quality, including in organic conditions. Henkieboy’s paternal grandfather is O-Bee Manfred Justice, aka ‘O-Man’. This is currently the most popular bull around the world for producing robust cows that perform well in organic conditions. om zijn robuuste vererving van wat laatrijpere en rondere koeien.
Bio Nieuw Bromo Jeroen

His grandmother Nannie 27 reached the age of 18 and had a lifetime production of 109,980 kg milk, with an average milk fat ratio of 4.38% and 3.36% protein. His father is the famous Dutch Whiteface bull Italie’s Paul, who is also known for high lifetime yields and excellent composition. The bull is clearly a cross. He is strongly built, moves easily, not particularly big at the age of 2, but has a good muscle mass. He also has a very gentle nature. Two daughters at his breeding farm are providing a good yield as first calvers. The bull has an Triple A code of 462, making him suitable for crossing with Holstein type cows in order to obtain cows who manage to give high yields without wearing themselves out.

Bio Arkemheen 110 is progeny from the Sofie family at the Lozeman FH breeding farm. His mother Sofie 104 produced nearly 60,000 kg melk with high milk fat and protein ratios. She maintained good lactation values until a ripe age and was awarded 85 points for AV. Sofie’s father, Arkemheen 57, as an AI bull with good breeding values for cell count (103), daughter fertility (101) and milk protein (+14%). Grandmother Sofie 82 had high yields with good composition for 5 lactations (average protein ratio 3.74%). Arkemheen 110 is a long-bodied, broad bull with good legs. Due to the kinship breeding system at the Arkemheen farms, the genes of his durable family are more homozygous anchored in his cells. That is why he will pass these genes strongly to his offspring. He is an excellent choice for robust cows.
