Prenatal Growth Of The Pig

Introduction

Numerous observations on various phases of growth are to be found in the biological literature. Most of those concerning prenatal growth are upon the human embryo, although scattered observations are also recorded on other mammals, and a few on the lower vertebrates. The work presented in this paper was done in the attempt to trace, in the pig, the course of the prenatal growth of the body and especially the relative growth of the various organs. The results are also compared with the course of growth in the human species and in the lower vertebrates, so far as data are available, The work was done in the Anatomical Laboratory of the University of Missouri, under the direction of Dr. C. M. Jackson, to whom I am deeply indebted for his interest, aid and valuable suggestions.

Material and Methods

The material used for this paper consists of 22 litters of pig embryos, comprising about 130 individuals, of which number 105 were used. In most cases, all the pigs of the litter were used, in the others, three or four specimens about the average of the litter were studied. These litters of embryos were secured from the packing houses in Chicago (August 31, 1909), Kansas City (December 27, 1909), and Columbia (at various times, spring 1910). Wherever possible, the litters were worked up in a fresh condition. In the other cases, they were preserved in a 5 per cent aqueous solution of formalin for varying lengths of time (table 1).
