The studies have been done on 12 pregnant and dried cows with an alimentary alkalosis. At pH of rument con­tent 8.27 ± 0.55 and arterial blood 7.54 ± 0.03 it was deter­mined in colostrum and milk pH. Soxhlett — Henkel — grade (°SH), density, the content of protein and fat inclu­ding percentage of fatty acids, the level of Na, K, Ca and Cl, time of casein curdling caused by renine. The samples of colostrum and milk were examined just after parturi­tion and then at the day 4 and 7 after parturition. In the all examined samples it was noted a shift of pH toward alkaline, a decrease of °SH and a specific gravidity, low level of protein and a high content of fat. In the colostral and milk fat the concentration of caprinic. laurinic and miristinic was low but the content of palmitinic, stearinic and linoleic acid was high. The ratio of saturated to unsaturated acids was 1.3. The samples of colostrum and milk showed a high con­tent of Na and Cl, low content of К and Ca. Time of curding caused by renine was prolonged. Colostrum of such parameters may cause in newborns the alimentary canal disturbances and affect negatively their resistance. Milk is devoid of the value of a food product and an industrial material. Alkalosis is connected with a low milk production. The studies have been done on 12 pregnant and dried cows with an alimentary alkalosis.
