BIOCHEMICAL INDICATORS AND APPLICATION OF Cyanobacteria Spirulina MICROALGAE IN THE CATTLE FEEDSTUFF

Аннотация

The qualitative and quantitative compositions of the valuable biologically active substances, species
and strains of microalgae are related the genus of Cyanobacteria Sp.platensis and Sp.labgrinthifosmis that were
isolated from local nature and grown in semi-production facilities were considered. In order to adapt for mass
cultivation, algae were first grown in greenhouse conditions. The algae were cultivated within 12 days. The productivity in the tubular cultivator with stirring of Sp.platensis was 3.8 g / l, protein (73.0%), and Sp.laberinthiformis was
2.6 g / l of protein (63.1%). Similar studies were carried out in the open-air conditions that showed an increase in the
amount of illumination causes a significant restructuring of the entire photosynthetic apparatus of algae. The
accumulation of Sp.labyrinthiformis 2.7 g / l a.d.c., protein 62.21%, and Sp.platensis 4.08 g / l, protein 75.3%, were
within 10 days. The content of protein and carotenes sharply increases in comparison with the greenhouse conditions.
It was found that the addition of Sp.platensis suspension, as a protein-vitamin supplement for the bulls’ feedstuff,
stimulates physiological processes that improves the biochemical parameters of their blood, the digestibility
coefficient of nutrients by 8-9%, positive mineral balance, increases live weight gain (17.4%) and slaughter yield of
the bulls (3.6%). So, the suspension of Sp.platensis is recommended for use as a protein-vitamin supplement in
livestock farms that will allow having a significant economic effect in livestock farming, in average 20-25% profits
per yearly
