[Biochemical quality assessment of broiler production using a hydrogen bacteria biomass in the diet].

The authors studied the biochemical composition of the meat of broilers, eggs, liver and muscles of laying hens of 3 generations on a 5, 10, 25, 50 and 100% (broilers), 10 and 20% (laying hens) replacement of the animal protein quota in the diet by protein obtained from the hydrogen bacteria Alcaligenes eutrophus L-1. No deterioration of the quality of the produce was found from the standpoint of the main biochemical parameters.

[Inclusion of chufa in the human diet as a source of polyunsaturated fatty acids].

In 2 experiments lasting 30 days each with participation of 6 volunteers the possibility of daily consumption in the diet of chufa in an amount allowing for minimal requirement of the organism in polyunsaturated fatty acids was studied. The experimental food ration accorded with individual requirements in its basic components. None of the participating volunteers demonstrated any untoward deviations of objective and subjective nature in their health status.

[Lipid metabolism in the far North aborigens residing in the Krasnoyarsk territory].

A study of the fat metabolism in the Extreme North aborigens, whose ration is made up chiefly of proteins and fats, demonstrated a decline of the most studied metabolic indices, as compared to those in inhabitants of the temperate geographical belt. Results of a fat load test speak in favour of the organism of the Transpolar aborigens adapting itself to the specific composition of the food ration in the course of ontogenetic development.
