[Normal values of various biochemical indicators in lowland black-white dairy cows from the government sector of the Gdańsk Coast. I. Normal values for the cow population].
The 29,489 test results of ten blood and serum biochemical parameters were analysed. The tests were performed in the years of 1974-1977 at 7229 lowland black-white cows, which were selected from the 80 herds of governmental farms on the Gdansk seaside. The herds were characterised by the productivity of 2500 to 3200 kg of milk per cow, the calving indicator higher than 80% and the lack of clinical diseases. All tests were accomplished by the use of methods commonly recommended in the literature and which could be used in any laboratory. The methods used in the work were characterised by enough good analytical accuracy and repeatability. The coefficient of changeability of chosen methods was comformable to the deviation of Tonks. It was established that the normal value ranges were as follows: glucose--1.98-2,58 mmol/l, total protein--67.2-79.2 g/l, albumins--27.0-37.8 g/l, urea--3.41-6.37 mmol/l, chlorides--99.81-107.83 mmol/l, sodium--138.78-149.02 mmol/l, potassium--4.31-5.21 mmol/l, magnesium--0.76-1.00 mmol/l, calcium--2.24-2.52 mmol/l, and inorganic phosphorus--1.57-2.31 mmol/l. The ranges of own normal values differed from the ranges of values cited in the literature.
