Merzlovа H. Biotechnology of Spirulina biomass enriched with Zinc and Cobalt, and its use for growing pigs.

The thesis is devoted to theoretical and experimental data on the optimal technical parameters to obtain biomass Spirulina platensis, enriched with metals, antibiotics and zinc cobalt proved its harmlessness and effectiveness of established feeding spirulina as part of animal feed for pigs starters. It was found that the optimum concentration of zinc and cobalt in the nutrient medium for Spirulina platensis in which cell division does not stop and most of these metals accumulate in the biomass are, respectively, 24.6 mg/L and 8.3 mg/l. Under these conditions, zinc and cobalt in dry matter Spirulina platensis is 0.32 g/kg and 155.9 g/kg, respectively. Experimentally proved harmless to white mice and rats, biomass Spirulina platensis, enriched with zinc and cobalt. Use of fodder for starter pigs biomass of Spirulina - enriched zinc 70.0 g/t and cobalt - 62.5 g/t enhances their body weight by 10.9 %.
