G.  aReproductive rates and growth of purebred brown swiss cattle in Brazil.h[electronic resource]  c1954  aThat cattle of breeds originating in europe thrive less well in tropical climates than in the regions of their origin is widely believed. The actual evidence is extensive enought to be convincing but is mostly from general observations or from experience of the "trial and error" kind, rather than fron experiments designed expressly to test the questions involved. Printed descriptions of such pertinent vital statistics as reproductive and growth rates, mortalities, length of life, etc., for whole populations of cattle in tropical and subtropical regions are rare.  aReprodução  aBovinos  aRaça suíça  aSwiss cattle1 aLUSH, J.
