The aim of this study was to determine the effect of fish-based feed materials, as a source of readily available protein contained in fish broth and essential polyunsaturated fatty acids (PUFAs) found in fish oil, on the health of piglets and rearing results. The experiment was conducted on a commercial pig fattening farm. The study involved a total of 80 weaners with an approximate body weight of 15 kg. The experiment was carried out over a period of 40 days. Feed samples were subjected to laboratory analyses. Blood samples were collected from experimental group animals to determine serum biochemical and immunological parameters. The body weight gains of weaners, mortality rates and average feed intake per animal were calculated for the entire experimental period. The addition of fish broth and fish oil significantly improved the n3:n6 fatty acid ratio in diets. The presence of EPA and DHA in the experimental diet could have had a positive health effect on piglets, comparable with that exerted by therapeutic doses of zinc often administered to pigs of this age group. During the experiment, feed conversion ratio (FCR) gain was considerably reduced in the experimental group, with similar daily gains in the control and experimental group.

Following the ban on using meat and meat-bone meals, fish and fish-derived products have become an alternative source of protein in swine nutrition. Fish broth, a by-product of fish meal processing, is one of these products. A prototype of pre-starter feed for piglets has been developed based on fish broth and fish oil and using extrusion processing. The aim of the study was to determine the impact of this feed on the health status and weight gains of piglets. Research was carried out on 20 litters comprising 230 piglets, 3-31 days of age. The chemical composition, amino acid composition of protein, and fatty acid content in fat extracted from the feed were determined and bacteriological investigation performed. Lipid metabolism parameters, selected biochemical indexes and enzymes and immunological parameters were determined. The weight gains of the piglets were recorded during the study and the results indicate that the improvement in the piglets’ overall health status was achieved in different ways. In group K it was probably due to a very high (therapeutic) level of zinc in the feed whereas in group D the significant content of Omega-3 essential fatty acids, in particular, may have had an impact on the good health performance of the piglets. This assumption is further confirmed by IgG and IgA concentrations.
