This investigation was carried out on 40 lactating Brown- Swiss at the age of 3-4 years belonging Konya Zootechnical Research Institute and on 2 cows with ketosis that were brought to ourclinics.

Before starting the experiments all of the cows were inspected clinically. Twenty cows which are due 30 days at maximum for calving and 10 lactating cows that were already parturated in o- 10 days were selected. In addition, 10 cows that were parturated 6 months ago were included for experiments as a control.

It was determined that all the animals during the pregnancy period w ere inefficien tly fe ed with coarse and consen tradet feed stuffs for the purpose of normal and easy parturation, and they gave lesser milk pro. duction as such 4- 5 litres per day on the average.

Blood glucose levels were measured in all the cows at about 10 days before calving and at the 10^th, 20^th and 30^th days of it there- after, and milk keton bodies were tested in milk and urine by rothera method.

Blood glucose values of all the animalls ·at about 10 days before calving and at the 10^th, 20^th and 30^th days of it were found to be 37.5 mg/dl, 32.5 mg/dl and 30.4 mg/dl respectively. It was determined that these values were increased up to 45.8 mg/dl after the addition of molassed sugar pulp to their ration 10 day later.

On the other hand, the blood glucose levels in· 2 cows with ketosis were 23 mg/dl at average. Following the treatment all of the animals were recovered and their blood glucose levels increased to 52.5 mg/ dl.
