ABSTRACT

The investigations were carried
out on 138 pig's foetuses, 68 male and 70 female. During the anatomical analysis,
the precise location and developental rates were estimated. The stomach location
was described according to sceletotophic, syntophic and holotophic methods. Whole
investgated material was statistically analysied. The highest stomach growth
rate was observed in the third and fourth age group. Sex and the uterus horn
location have not significant influence on any parameter measured and calculated
in foetal pig stomach description. The mean value of stomach length indicates
the linear (isometric) growth rate according to subsequent age groups and it
is twice larger than the average width and thickness of stomach in the same group.
The mean value of the width / length index equals 55.82%. It indicates the medium
– wide shape of stomach in foetal period in toto. The value of this index
in subsequent age groups clearly describes the dynamic processes of the shape
and size rates changes in development of pig's stomach between the 35^th and
114^th day of pregnancy.

Key words: pig, stomach prenatal life, morphometry.
