In this study an attempt was made at estimating the relationship between the
intake of linoleic and linolenic FAs and their deposition in the whole body. Both are
of essential importance in many metabolic processes, but cannot be synthesized by
pigs. That is why they are considered exogenous and must be supplied in the diet.
The aim of the present investigation was to separate from energy conversions in
the body a part which animal deposits as fat and fatty acids. Furthermore, an attempt
was made at determining the intake of linoleic and linolenic acids from the diet
on their utilization efficiency by pigs. Information received will be used to study
the nutritive model of FAs in growing pigs. Moreover, the results will correct the
data on nutritive requirements of pigs and improve the quality and health-promoting
properties of pork.
It was assumed that replacing part of the dietary metabolizable energy by fats with
various content of fatty acids, will not change the amount of fat and total FA in the
whole body, but FA composition of the body fat will be altered.
