Abstract
To determine whether some of the alterations previously observed in the blood lipids and phosphatase values of cows with ketosis are due to ketosis per se or secondarily to the inanition associated with ketosis, 16 cows were used in a study of the effect of different levels of protein and energy intake postpartum. The postpartal plasma lipid values of cows receiving 70-80% of their total digestible nutrient requirements were similar to those of cows in the early stages of ketosis. The postpartal plasma lipid values of cows receiving only 35% of their total digestible nutrient requirements were similar to those of cows in the later stages of ketosis. Complete fasting for 8 days produced alterations of the same nature but of greater magnitude.Keywords
