Mammary blood flow and cardiac output in the conscious lactating rabbit


  1. 1.

    Cardiac output and regional blood flow were measured in conscious lactating and non-lactating rabbits.

  2. 2.

    At 14 days post-partum the cardiac output in lactating rabbits was 30% higher than that measured in virgin animals.

  3. 3.

    The mammary gland was the only organ to show an increase in relative weight (% body weight) during lactation and also the only organ to receive an increased proportion of the cardiac output per g tissue weight during lactation.

  4. 4.

    These results are discussed in the context of net substrate uptake by the lactating rabbit mammary gland.
