With this, the herd of the Hermanussen family from Beers (The Netherlands) has already attracted attention for years. Since Barendonk Holsteins has been active as a CRV test farm, former donors of the Delta breeding programme have been pushing up the number of 100-tonners.
Seven 100-tonners in a year and a half
Former donors of the breeding programme are well represented in the list of the seven 100-tonners of the past eighteen months. Since 2012, every year ten to fifteen Delta heifers have been enrolled in the dairy herd at the CRV test farm that counts 270 animals. Four animals of the first groups of Delta donors reached the milestone of one hundred thousand litres. Is this a coincidence or a result of selection by CRV? We are asking Marcel Fox, coordinator of the Delta breeding programme.
