Abstract
(1) Methods of lipide analysis have been surveyed
and suitable techniques adopted for a study of
tissue lipides in domestic animals.
(2) Data are presented for liver lipides in twenty-five
non-pregnant and ninety pregnant ewes,showing
that fatty infiltration of the liver is quite
common in apparently healthy pregnant animals.
These findings are analysed in detail.
Analyses of kidney specimens from the same
animals are also recorded.
(3) The effects of castration and of pregnancy
toxaemia on tissue lipides have been examined
and discussed.
(4) Original data are given for blood lipides in the
sheep, along with a survey of the effects of
pregnancy and of fasting on the various fractions.
(5) The operation of partial hepatectomy has been
successfully adapted for use in ruminants and
applied to a study of the effect of fasting on
liver fat.
