Contents: In the final experiment of the series, 189 blood samples, collected from lactating sows in weekly intervals (1–6 weeks post partum) during the four seasons in a tropical environment, were analysed for 23 different cellular, gaseous, and biochemical parameters. Significant changes were noted in the following chemical blood components: plasma proteins, blood glucose and inorganic phosphorus content, all of which showed a steady decline which, in a way, wassimilar to the decreasing body weight curve during lactation. Lactate dehydrogenase activity was depressed two weeks after parturition only.
