The work was performed under the conditions of the southern forest-steppe of the Middle Volga region in 2018–2021. The material for the study was represented by five promising populations of alfalfa. The released variety Izumruda was taken as the standard. The soil of the experimental plot was represented by typical medium-humus heavy loamy chernozem with the humus content of 5.2% in the plow layer; the content of mobile potassium and phosphorus (according to Kirsanov) at the level of 292 and 156 mg/kg of soil, respectively; the amount of easily hydrolyzable nitrogen of 116–132 mg/kg of soil, and pH of salt extract equal to 6.9–7.2. The seeding rate was 15 kg/ha. The largest total mean yield of green mass for the years of research was provided by samples Populyatsiya 24 (39.5 t/ha), Temno-zelenaya (39.9 t/ha), and Populyatsiya 13 (40.2 t/ha), which was by 11.0–12.9% higher than the yield of standard variety Izumruda. The production of dry matter in total of two cuttings was the highest for the varieties Populyatsiya 4 (9.4 t/ha), Temno-zelenaya (9.5 t/ha), and Populyatsiya 13 (10.2 t/ha), which exceeded the standard by 11.9–21.4%.

The purpose of this study was to determine the effect of different methods of preparation (centrifugation or filtration) of rooster semen on its quality characteristics, depending on the method of removing possible pollutions; to evaluate the change in the composition of the cytosol of spermatozoa of native sperm under the influence of dilution and during short-term storage. Materials and methods. Semen of roosters (<em>n</em> = 22) of the Russian white breed was used. Experiment 1: semen was divided into 3 aliquots: I—diluted with synthetic cryoprotective medium LCM in a ratio of 1:1, II—filtered semen diluted with medium (membrane pore diameter 0.2 μm), III—centrifuged (at 3000 rpm in for 10 minutes). Native and frozen/thawed sperm were evaluated in terms of damage to spermatozoa membranes, chromatin, and acrosomes. The composition of carbohydrates and polyols of native spermatozoa was assessed under the influence of dilution and after storage (3 h). The advantage of filtration as a method of technological preparation of semen compared to centrifugation in terms of progressive motility (with rectilinear-translational movement) of sperm (41.0% versus 27.0%) and chromatin damage (43.4% versus 66.4%) has been shown. The same advantage was observed in frozen/thawed sperm filtered before freezing in terms of progressive motility (25.5% vs. 5.5%) and chromatin damage—16.5% vs. 33.6%, respectively. Semen filtration, as a method of technological processing of rooster semen, can be an effective additional step in the preparation of semen for artificial insemination and/or short-term storage. The main component in the composition of the cytosol of native spermatozoa, according to the content of carbohydrates and polyols, was inositol —73.7% of Σ carbohydrates and polyols. The level of inositol decreased during storage by 6.5 times (from 0.030 to 0.007 mg/mL). The data obtained let us suppose the role of inositol as the main antioxidant in the cytosol of spermatozoa. Technological factors of storing rooster semen in various modes (short-term at a temperature of 5°C and long-term at a temperature of –196°C) have a significant impact on the ratio of sperm cytosol components (carbohydrates and polyols). A significant, 2.5‑fold decrease in the relative content of inositol in the cytosol of frozen/thawed spermatozoa, compared with the indicators of native semen, allows us to recommend the introduction of the antioxidant inositol into the composition of cryoprotective media for rooster semen.</p> </span>","PeriodicalId":21531,"journal":{"name":"Russian Agricultural Sciences","volume":"6 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139557804","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The experiment’s design was as follows: without fertilizers: N₉₀; Р₉₀; K₉₀; N₉₀P₉₀; N₉₀K₉₀; P₉₀K₉₀; and N₉₀Р₉₀K₉₀. To assess the effect of nitrogen, phosphorus, potash fertilizers, and their combinations on the nitrogen regime of sod–podzol soil, arable soil was compared with the virgin analog.

The survey was performed based on pedigree and commercial cattle farms in Smolensk oblast with the grouping method. Phenotypic correlations between the analyzed production traits were estimated. Holsteinization of the Black-and-White breed in the Smolensk oblast resulted in its absorption through crossing the cows with Holstein sires to have a Holstein blood percentage of 90.0%. The survey outcomes have revealed a regularity indicating that the higher the percentage of Holstein blood is, the shorter longevity of cows is observed. The difference in lifespan of cows with Holstein blood percentage from 17.6 to 87.1% comprised 4.36 lactation cycles. The productive lifespan of cows can reach 12–13 lactation cycles. However, 50.9% of these animals are culled between the second and fourth lactation cycles. The ratio of days in milk to days dry in dairy cows tends to change with aging. Thus, the longer the productive lifespan in cows is, the higher the number of days in milk per each year of life, on average, is recorded. The major proportion of cows is productive within the ratio of days in milk to lifetime days, varying in the range of 50.1 to 75.0%. Their lifespan is measured by 4.3 lactation cycles. The lifetime milk yield usually varies from 10 000 to 30 000 kg (for 56.7% of the analyzed livestock). The parameter for lifetime daily yield is reasonable to use as an indicator of cow productive lifespan due to its strong positive correlations (<em>r</em> = 0.44–0.90) relative to age-related and productivity performance.
