Melkproductiecontrole in het Zuidhollandse Utrechtse kaasdistrict
1942
Schiere, C.
Milk recording is an important factor in checking the profitability of dairy farming. In the cheese district considered, where full-cream Gouda cheese is produced on the farm, the customary records of milk yield and fat content were insufficient, because output was determined by the cheese yield of the produced milk, which in its turn depended largely on the casein content of the milk. It was found that the rather weak correlation between fat and casein contents could not serve as a basis for prediction of the cheese yield in practice. Therefore a simple method was devised for estimating the yield of fat-free cheese. This factor was found, however, to correlate sufficiently well with fat content and density of the milk. Consequently, a multiple regression equation was calculated between percentage cheese yield, and fat content and density, that could successfully be applied in profitability checks and for breeding programmes.
