The article is devoted to the adaptation of imported cattle in the Republic of Sakha ( Ya kutia ) . The aim of the research is to assess the adaptation of breeding dairy cattle imported to the Republic of Sakha ( Yakutia ) to the extreme climatic conditions of the region. In the period from 2013 to 2022, 3856 heads of high-yielding breeding cattle were imported: Red Steppe breed , Black Pied breed, Red and White breed and Holstein. The research was based on the annual farm reports and the results of blood molecular genetic diagnostics by the laboratory of Sahaagroplem.

Industrial fish farming is the most dynamically developing area of domestic aquaculture. Therefore, the problem of obtaining live feeds for growing juvenile fish under artificial conditions is of utmost importance, since such feeds are characterized by high nutritional value, high content of protein, fat, essential amino acids, vitamins, enzymes and other important components.

Peculiarities of using bioorganic fertilizers on leafless pea varieties

Submitted by Гость (not verified) on Mon, 01/13/2025 - 14:38

Открыть

Recently, the safety of agricultural products has become a rather relevant aspect. One of the ways to solve this problem is the use of biological preparations. The aim of the research was to determine the effectiveness of using bioorganic fertilizers on leafless varieties of peas. The article presents the results of research into the effect of bioorganic fertilizers on the productivity elements of pea varieties. Pea seeds were treated with the studied preparations before sowing and during vegetation.

Producing high quality cow milk is a priority for agricultural enterprises. Mastitis has a major impact on milk quality due to the increased somatic cell count in milk and the bacterial contamination of milk with microorganisms. To solve this problem, an experiment was carried out to study the effect of vaccinating cows on the incidence of their mastitis and on the somatic cell count in the milk. During the study period, it was found that the cows in the experimental group ( vaccinated animals ) had 6.1 times less mastitis than the control group ( unvaccinated animals ) .

Effect of exogenous phytohormones on the ovule development in the hybridization of Solanum lycopersicum and Solanum sisymbriifolium

Submitted by Гость (not verified) on Mon, 01/13/2025 - 14:38

Tomato crops are susceptible to a significant number of diseases that reduce both yield and product quality, requiring the improvement of genetic diversity and the creation of genetically resistant varieties. Solanum sisymbriifolium Lam. is a source of resistance to bacterial wilt, verticillium wilt, root nematodes, carmine spider mites and late blight. The hybridization of tomato and sticky nightshade is feasible, but involves difficulties in overcoming prezygotic and postzygotic barriers to non-crossing.

The study analyzed the genetic diversity of polymorphism in the calpain ( CAPN1 ) and leptin ( LEP ) genes in ewes and rams of the Kalmyk fat-tailed breed and the influence of different genotypes on their live weight and average daily gain. It was found that the proportion of the C allele in the CAPN1 locus was higher in rams, while the T and C alleles were equally frequent in ewes. The T allele was more common in ewes and rams than in the parent stock. In the LEP locus, animals with the AG genotype were most common.

Age-related prolificacy dynamics in mini-pigs of ICiG SB RAS and its association with the white coat color

The article presents the results of the prolificacy dynamics analysis ( the number of newborn piglets per litter ) in the mini-pig breeding group of ICiG SB RAS. It is shown that the form of agerelated dynamics of this trait in mini-pigs differs significantly from that described earlier in the Kemerovo breed. In the latter it has the shape of a parabola, in the former it has two consecutive rectilinear segments.

The article is dedicated to the scientific and pedagogical activity of the outstanding Russian botanist, popularizer of science, Doctor of Biological Sciences, Professor Oleg A. Korovkin, one of the founders of the Morphological School of the Timiryazev Academy. A brief biography of the scientist is given, his contribution to Russian and world science is reflected. For many years, the scientific interests of O.A. Korovkin have been related to the study of the morphogenesis of vegetative organs of flowering plants, including the ontogenesis of stoloniferous herbaceous polycarpic plants.
