Abstract
This article reports on an investigation which was carried out to determine the influence of different copper source in diet of growing- fattening pigs on iodine number and fatty acid composition of belly fat. The experimental pigs were fed the same basic ration supplemented with 250 ppm Cu as follows: Group I CUSO₄, Group II CuCO₃, Group III CuO, Group IV CuCl₂. From the results of the investigation the following conclusion could be drawn: 1) Different sources of copper in diet of growing- fattening pigs have not had significant effect on iodine number of belly fat and sum of the saturated and unsaturated fatty acids respectively (P>0.05). The content of the single fatty acids was not identical in samples of the belly fat. 2) In relation ,to the iodine number acid the sum of the saturated and the unsaturated fatty acids respectively of the backfat samples of the same pigs (Crnojević and collaborators, 1975) the belly fat samples have had very significantly different results (P<0.01).
