Often the random vector variable, X, being encountered, for example, in atmospheric, biological, economic and environmental and other research, is of a large dimension but admits of meaningful grouping(s) into two or more mutually exclusive and exhaustive subvectors. Dimension reduction techniques are then sought to obtain “representative” new variables for each group to be formed by taking sui...

This study was carried out to investigate the effects of starvation and feeding regimes on growth performance, haematological and biochemical parameters of blood and body composition of Caspian brown trout parr. For this purpose, 900 fish (average weight: 12.5±1 g) were stocked in 300-l tanks (18 tanks at a stocking rate of 50 fish in each tank) using an open system. Six experimental groups com...

In today's conditions, the issues of feeding, maintenance, upbringing, training, and prevention infectious diseases were are relevant in dog breeding. Many primarily foreign scientists conduct research this field science. However, Ukraine do not pay enough attention to study improvement technology for feeding keeping dogs kennels departmental institutions, mainly where used help people serve. A...
