title: [The effect of the temperature of a milk drink on physiological indicators in the blood of calves].
abstract: In a set of 11 young heifers-crossbreds in the period of milk nutrition the influence of the temperature of milk nutrition the influence of the temperature of milk drink was studied as exerted on haematological data (haemoglobin and haematocrit), on the values of nitrogen metabolism (total protein and urea), on the components of energy (glucose and cholesterol) and on alkaline blood reserve. In these values we did not record any statistically significant differences between the groups. The subnormal values were demonstrated for cholesterol which we regard as a response to the lower content of fat in milk replacers. Furthermore, the activity of ALT and AST enzymes was examined. A significantly lower ALT and AST activity was recorded in calves administered cold Lactosan. It indicates a possibility of feeding milk replacers at the temperature of stable environment. The heifer calves were to get used to cold drinks by means of Rehyvet, the pH-value of the drink being 4.6.
