Assessment of nitrite and transferrin levels in the blood of cows with subclinical mastitis by the electron paramagnetic resonance method

Submitted by Гость (not verified) on Thu, 05/15/2025 - 13:38

A major problem in veterinary medicine is the lack of timely and quantitative diagnosis of subclinical mastitis in highly productive cows. Currently, the main indicator for diagnosis of udder pathology is milk analysis for leukocytes (i.e., neutrophils, macrophages, lymphocytes) and epithelial cells. Inflammation in the mammary gland is directly related to nitric oxide synthesis and the paramagnetic NO complex with hemoglobin has characteristic spectroscopic parameters of hyperfine cleavage.

The steady increase in state support for agriculture in Russia requires maximum efficiency in its use. In 2024, the volume doubled compared to 2018, reaching 558 billion rubles. The analysis indicator system outlined in the article reveals the effect of the state support amounts allocated to the agroindustrial sector during the monitoring process. The optimal subsidy amounts for achieving maximum efficiency by agricultural producers are determined based on factual material.

The article presents the results of studying the effect of ammophoska encapsulated with monocalcium phosphate (Ca(H2PO4)2) of different thickness on the yield and quality of soft spring wheat of the Lubava variety in the conditions of the Non-chernozem zone of Russia. The fertilizers developed by the National Research Institute of Agricultural Sciences named after Yu.V. Samoilov help to reduce nitrogen losses of fertilizers due to delayed release of the active substance, thus improving the nitrogen nutrition of cultivated plants.

Crimea is one of the few regions of our country, which has a mild subtropical climate and historical traditions, and the most favorable conditions for cultivation of olive (Olea europaea L.) To develop this crop, planting material must be produced from the most adapted varieties. Rooting cuttings during the vegetative propagation of olives is a slow process because olives are hard-to-root crops. The aim of the study was to develop methods to increase the rootability of European olive cuttings.

The state program for the effective involvement of agricultural lands in the turnover and development of the reclamation complex of the Russian Federation has contributed to the active return of fallow lands to arable land, which in turn opens up new opportunities for studying changes in soil properties in such conditions. The article examines the issue of changes in the content of humus and labile organic matter of leached chernozem (Luvic Chernic Phaeozems) of the forest-steppe zone in the conditions of the Tula Region upon return to arable land from the fallow state.

This article presents the results of the three-year data analysis of DUS testing of the spring wheat (Triticum aestivum L.) collection by morphological varietal characteristics. The following cultivars were identified as candidates for example varieties: Ivolga, Iren’, Lisa, Talba, Chelyaba rannaya, Bazhenka, Grechanka, Dal’gau 3, KWS Shirokko, Silantiy, Start 1, KWS Torridon. These varieties reflect all the gradations of found characteristics.

The morphobiological and phenological features of ten cultivars of Hibiscus syriacus L. were investigated. These cultivars were introduced from Simferopol Botanical Garden and are growing in the collection of Donetsk Botanical Garden. The plants grow in the open ground and are protected from the cold. The cultivar Carneus Plenus exhibited the highest degree of shoot freezing, up to 50% of the length. Vegetation starts almost simultaneously in all cultivars – from the second decade of April.
