On Thursday afternoon, May 24, 2018, I made recordings of Jakob van Biert. He works at the AB Zuid-Holland teamwork in staff. These skilled temporary workers can be flexibly deployed for the most diverse activities in the agricultural sector, on arable farming and livestock farms. Jacob is also working at the grain silos of the CZAV in August. Jacob is specialized in treating the hooves in the cattle '' cattle pedicures ''. This afternoon he has taken care of a dozen dairy cows at the modern dairy farm of Boer Huibert Groeneveld at Boerenweg 10 in Sommelsdijk.
