[Changes in the blood biochemical indices of lambs weaned at different ages].

Studied were the changes in the Ca, P, Mg, total protein, and protein fractions in the blood serum, and the Na and K in the plasma and erythrocytes in three groups of lambs weaned on the 5th, 15th, and 20th day after birth. The changes in these indices both in the test and in the control lambs varied within the normal range for a given age. In the control lambs there were higher values of K, lower values of Na in the erythrocytes, and lower values of the blood sugar. Presumably, this was due to the adaptational changes in the animals in connection with the modified way of feeding. The conclusion was drawn that early weaning coupled with the use of the SEC Mlechna Promishlenost milk replacers could be introduced in the practice of lamb fattening.
