Reproduction rate of Holstein cows and its dependence on herd age structure

Submitted by Гость (not verified) on Wed, 02/04/2026 - 22:38

This study analyzes key fertility indicators, specifically the service and interbody periods, which are limiting factors in reproduction rate. This study is relevant because it quantifies hidden offspring losses due to cow mortality, allowing for a more accurate assessment of potential offspring production within the herd. The research aims to determine the impact of age variability on fertility and to quantify hidden offspring losses associated with younger cows in a high-producing dairy herd.

Evaluation of Simmental cow milk component composition in relation to feed nutritional value

Rationing of dairy cattle is one of the critical challenges faced by every farm. A comprehensive approach to addressing this challenge involves both theoretical substantiation and practical analysis of the actual composition of both feedstuffs and the resulting milk. Crucially, regular milk analyses enable the “response” to be recorded, allowing for an assessment of the actual level of nutrient assimilation and transformation from the diet. Our investigation was conducted as a single-point study on Simmental cows (n = 15) at a training farm located in the Voronezh Region.

Intensive technologies contribute to increased productivity in aquatic animal farming, but they also create a number of problems associated with increased stress on the fish body. This is due to the stress caused by specific aspects of the intensive approach. Nile tilapia (Oreochromis niloticus) is a widespread species that is well-suited for commercial cultivation due to its high growth rate, high market value, and significant resistance to biotic and abiotic stressors.

The present study investigates the intensity of muscle growth in various anatomical parts of carcasses in Black-and-White heifers and their crosses with Hereford and Charolais breeds. It was established that muscle growth exhibits significant variability, influenced by functional load, genetic factors, and the ontogenetic stage. The most intensive growth was observed in the abdominal musculature, where muscle mass increased by 25.97 times by 18 months of age, significantly exceeding the overall growth rate of carcass muscle mass (16.08).

Sclerotinia sclerotiorum is a dangerous, highly specialized necrotrophic phytopathogen that infects approximately 400 plant species, including economically important crops such as sunflower, rape-seed, soybean, and others. This fungus causes white mold (syn. sclerotiniosis), one of the most destructive diseases, especially in regions with cool and humid climates. The pathogen S. sclerotiorum has a simple life cycle, where infection occurs either via mycelium from dormant sclerotia in the soil or by ascospores from apothecia.

Effect of Isabion on productivity components of remontant raspberries

Submitted by Гость (not verified) on Wed, 02/04/2026 - 22:38

Открыть

Currently, there is a heightened demand for off-season raspberry fruit. Consequently, the aim of this work was to investigate the effect of the biostimulant Isabion on the growth characteristics and productivity of red raspberry plants of the remontant type of fruiting under the conditions of the Central Black Earth Region.

Selection of promising winter barley base lines using complex assessment of identifiers

Submitted by Гость (not verified) on Wed, 02/04/2026 - 22:38

Открыть

The study aimed to conduct a complex assessment of winter barley base lines to select promising parental lines for inclusion in a hybridization program. This article presents data from field and laboratory trials conducted between 2022 and 2024, identifying the most promising winter barley varieties and lines from the collection at the Agricultural Research Center “Donskoy”. In autumn, 119 collection samples were sown at optimal agronomic times using a Wintersteiger Plotseed seeder to select the most promising (valuable) genotypes for use in breeding programs.
