BIOLOGICAL AND PRODUCTIVE RESOURCES OF LACTATING COWS AT DENITRIFICATION
DescriptionThe article presents the results obtained in the process of two scientific-practical experiments carried jut on two milk cows (Shvitskay breed) aimed at the antioxidants detoxication properties and mould inhibitor revealing. This factor is actual in the Republic of North Ossetia-Alania as the intensive technologies of the fodder crops cultivation using the nitrate fertilizers are widely applied in the region leading to the excess nitrates and nitrite penetration into the animals’ organism. During the first experiment, the antioxidants of epophen and vitamin C were added into the ration of the lactating cows with the subtoxic dosage of nitrates both separately and in complex. The complex feeding proved to increase the milk productivity, the fat mass and protein mass in milk while reducing the fodder expenditure per product unit. Beside, the lactating cows revealed the digestive and intermediate exchange betterment and the reduction of nitrates and nitrites level in blood. The second experiment helped to study Khadoks antioxidant and mould inhibitor called Mold-Zap efficiency use for the nitrates and aflotoxicin B1 detoxication. The researches showed that the complex admixtures of the said preparations introduction into the rations of the animals increased the milk productivity, fat and protein content and reduced aflatoxineM1 content. The cows activated the digestive and intermediate exchange, accompanied with the nitrates and nitrites level reduction in the organism

BIOLOGY OF SEED GERMINATION OF SOME SPECIES OF FAM. ROSACEAE JUSS
DescriptionWe have studied the germination and the nature of germination of seeds of 20 species of FAM. Rosaceae. A wide range of germination characterizes their seeds: rapid, slow, with very poor or no germination. Laboratory germination of seeds stored at room temperature for 6-7 months have 80-100% - 8 species, 66-77% - 3, 1-9% - 4 species and 5 species did not germinate at room temperature, they need special conditions for germination
