Published online by Cambridge University Press: 27 March 2009
Extract
In the spring of 1937 an experiment was conducted to test existing commercial facilities for the transport of bull semen between England and Holland. Samples were sent to and received from Holland via Royal Dutch Air Lines, to whom the authors wish to express their sincere thanks for most useful co-operation. The minimum interval between collection in one country and insemination in the other was 28 hr. and the maximum, 57 hr.
