DescriptionThe article describes the evaluation of reproductive, fattening and meat qualities of pigs of purebred large white breed (KB), crossbred ewes, derived from crosses KB sows with boars of steppe type (ST) CM-1 and three-pedigree animals, obtained by crossing crossbred ewes KB x ST with imported boars of specialized meat breeds, such as Landrace (L) Duroc (D) and pietrain (P). We have studied qualities such as prolificacy, milk yield, live weight of the nest, the average weight of one Piglet, the safety of the offspring to weaning, maturity, which is closely associated with average daily gain in live weight, meat content of carcasses, their linear dimensions, meat productivity, the amount of kidney fat, weight of carcasses of animals of the experimental groups, carcass yield

EXTRACTION OF DNA FROM HERBARIUM LEAVES VITIS VINIFERA L.
06.00.00 Agricultural sciences
DescriptionTwo methods were used for DNA extraction from herbarium leaves of two subspecies: V. vinifera subsp. sativa D.C. и Vitis vinifera ssp. silvestris Gmel. DNA extraction is difficult from herbarium leaves plants because of the presence of metabolites that interfere with DNA isolation procedures and downstream applications such as DNA restriction, amplification, and cloning. The quality of DNA was checked on a spectrophotometer by measuring the level of absorption at A260/280 nm. The results showed the successful extraction from mature and dried leaves of DNA when using the СТАB-method №2. Another method hasn’t shown satisfactory results in amplification of DNA

EXTRACTION OF DNA FROM LEAVES OF VITIS VINIFERA L.
06.00.00 Agricultural sciences
DescriptionExtraction of the DNA from leaves of genus Vitis is a very difficult task, as a grape has a lot of elements, which make difficult to use it in the genetic manipulation. In that article used the methods of extraction of the DNA with silica (SiO2) particles as the absorbent material for getting better quality DNA
