Ecological and Technological Evaluation of the Nutrition of Perennial Legumes and their Effectiveness for Animals

Abstract

Main task of feed production is to provide farm animals with nutrients. Insufficient or excessive intake of these elements can lead to undesirable consequences. For instance, a deficiency in mineral elements reduces the protective function of the animal's body against various diseases and disrupts the functional activity of organs. Conversely, an excess of any element contributes to the expenditure of a significant amount of energy for its removal and, in some cases, leads to poisoning. Imbalanced animal feeding results in decreased productivity and a deterioration in the quality of products, leading to the production of non-viable offspring and a disruption of reproductive capacity. Our calculations have shown that increasing the energy concentration in the diet from 490 to 600 EFU/kg DM, combined with an increase in feed intake by 4.4 kg, ensures proportional energy consumption based on their productivity difference. In our research, we concluded that it is economically advantageous to use the planned norms of the nutrient requirements for cattle in feed planning.

Study of the Impact of Changes in the Acid-Base Buffering Capacity of Surface Sod-Podzolic Soils

“…These criteria refer to fixed indicators of soil samples from genetic horizons of a certain soil variety during the initial observation period. To assess the agroecological condition of the soil, it is recommended to use parameters of virgin soil or fallow land that has not been used for agricultural purposes for 20 years or more [Medvedev, 2012;Medvedev and Laktionova, 2012;Kovalenko et al, 2024a].…”

Simulation of High–Product Soy Crops Based on the Application of Foliar Fertilization in the Conditions of the Right Bank of the Forest steppe of Ukraine

“…A decrease in the level of soil acidity can worsen its nutritional regime and the availability of nutrients for plants. Soil liming primarily affects the reduction of acidity, and therefore it is important to establish how soybeans Simulation of High-Product Soy Crops Based on the Application of Foliar Fertilization in the Conditions of the Right Bank of the Forest Steppe of Ukraine Oleg Kolisnyk 1 , Liudmyla Yakovets 1 , Sergey Amons 1 , Andrii Butenko 2* , Viktor Onychko 2 , Olena Tykhonova 2 , Anna Hotvianska 3 , Natalia Kravchenko 2 , Ihor Vereshchahin 2 , Vitalii Yatsenko 2 react to gradual changes in soil acidity, moving from highly acidic to nearly neutral soil, and to determine the optimal conditions [Palamarchuk et al, 2010;Bakhmat et al, 2017;Ivanov et al, 2019;Kovalenko et al, 2024b].…”
