Abstract
The relationships between body composition, live weight (LW) and subje ctive condition score (CS) were examined in an experiment in which 54, second to fourth parity, lactating autumn-calving Holstein-Friesian d airy cows were slaughtered at 0, 2, 5, 8, 11, 14, 19, 24 and 29 weeks post partum. Multiple regression analyses showed the weight of fat and the quantity of energy within the body were significantly correlated with both LW and CS. The weight of crude protein showed a linear corre lation with LW. These results are discussed and compared with previous ly published investigations with non-lactating dairy cows.
