“…This cooperation would objectively align feed requirements with their supply over a specific period and effectively influence the stability and predictable increase in production. Therefore, the implementation of industrial feed production methods in the assessment of new feeds brings forth new requirements and challenges [Petrichenko and Antipova, 2019;Lü et al, 2019;Guo et al, 2023].…”

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.

“…Yield is the most important comprehensive indicator of the economic value of a crop that combines individual plant performance, biocoenotic factor and environmental conditions. Therefore, only with the optimal combination of all factors, we can expect a high crop performance, as a result of the factorial action of the potential performance and environmental resistance systems [3]. Stabilization of crop production, along with the rational arrangement of crops and other factors, is largely determined by growing requirements for the selection of varieties best suited for growing in different soil and climatic zones and characterized by high environmental plasticity.…”

Purpose and objectives. To determine peculiarities of the fulfillment of the yield potential of modern soybean varieties in different soil and climatic zones of Ukraine. Materials and methods. Fourteen soybean varieties bred at PPI NAAS and included in the State Register of Plant Varieties Suitable for Dissemination in Ukraine were studied: Podiaka, Malvina, Estafeta, Sprytna, Baika, Krynytsia, Kobza, Pysanka, Perlyna, Melodiia, Rainduha, Krasunia, Rizdviana, and Sloboda. The soybean yields were evaluated in the competitive variety trial (CVT) of the Laboratory of Grain Legume Breeding. The experiments were carried out in four replicates. The record plot area was 25 m2 in accordance with the state variety trial methods. For comparison, we used data on the yields of the same varieties obtained during the qualifying examination for suitability for propagation (SVT) of the Ukrainian Institute of Plant Variety Examination (UIPVE). Data were statistically processed, as B.A. Dospekhov described [18], using STATISTICA 10 and Exel. Results and discussion. It was found that the most favorable conditions for growing soybean were in the Forest-Steppe, where the average yield amounted to 2.22 t/ha with fluctuations within 1.94–2.47 t/ha. In the Woodlands, the yield averaged 1.99 t/ha, varying 1.76 t/ha to 2.28 t/ha. The worst conditions were observed in the Steppe, where the average yield was 1.85 t/ha with fluctuations within 1.38–2.25 t/ha. The yield averaged 2.02 t/ha across the SVT zones with the maximum of 2.15 t/ ha and the minimum of 1.83 t/ha. The minimum fulfillment of the yield potential (FYP) in the CVT was 41.3% related to the average across the climatic zones of Ukraine. The maximum FYP in the CVT reached 95.6%. On average, there was a 67.8% fulfillment of the yield potential of the soybean varieties in the CVT. At the same time, the FYP was revealed to depend on the hydrothermal conditions of the test years. The lowest FYP in the CVT was recorded for variety Sloboda (41.3%), which was tested under the unfavorable weather conditions for soybean in 2017 and 2018, when the average yield of the CVT accessions was 0.84 t/ha and 0.50 t/ha, respectively. The average yield from Sloboda in the CVT was 0.85 t/ha, while the average yield in the SVT was 2.06 t/ha. The yield loss was 58.7%. The highest FYP in the SVT was recorded for varieties Krasunia (95.6%), Melodiia (91.4%), Raiduha (84.2%), and Rizdviana (79.5%). For these varieties, the differences in the yield between the CVT and SVT were significantly lower (4.4–20.5%). The relatively high yields from these varieties in the CVT is attributed to the favorable conditions in 2016, when the CVT yield reached the maximum over the study period (2009–2018); the average yield of the varieties amounted to 2.59 t/ha. Conclusions. The most favorable conditions for soybean cultivation were in the Forest-Steppe of Ukraine. The average yield in this zone was 2.22 t/ha with fluctuations within 1.94–2.47 t/ha. In the Woodlands, the average soybean yield was 1.99 t/ha, ranging 1.76 t/ha to 2.28 t/ha. In the Steppe, the average yield was 1.85 t/ha, with the minimum of 1.38 t/ha and the maximum of 2.25 t/ha. The yield across the SVT climatic zones averaged 2.02 t/ha, with the maximum of 2.15 t/ha and the minimum of 1.83 t/ha. The minimum FYP in the CVT was 41.3%; the minimum yield was 0.85 t/ha in the CVT and 1.83 t/ha in the SVT. The maximum FYP in the CVT reached 95.6%; the maximum yield amounted to 1.75 t/ha in the CVT and 2.15 t/ha in the SVT. The average FYP in the CVT was 67.8%; the average yield was 1.37 t/ha in the CVT and 2.02 t/ha in the SVT. The fulfillment of the yield potential was revealed to depend on the hydrothermal conditions of the test years. It was demonstrated that the high genetically determined yield potential of the soybean varieties was significantly offset by unstable hydrothermal conditions during the soybean growing period, causing considerable fluctuations in the yields. For a more objective analysis of the yield in the competitive trials of soybean varieties, it is necessary to take into account not only the absolute yields of promising accessions, but also the total yield of the crop in individual years of research.

Purpose. To establish changes in the state of production of fodder crops under arid conditions of the Southern Steppe of Ukraine (on the example of Mykolayiv region) and to determine the consequences for providing feed to the livestock industry. Methods. Analysis, synthesis and comparison. Results. The analysis of the state and development of production of feed crops in conditions of the South of Ukraine is carried out. Changes in the structure of sown areas have been established. Thus, in the total sown area in 2000 the share of feed crops consisted 17.1%, and in 2019 this figure decreased to 13.9 percent. At the same time, the sown area under industrial crops increased to 37.6% (by 15.8 percentage points). Changes in the structure of sown areas of feed crops, giving preference to growing grass for hay, have improved the productivity of these agrophytocenoses. Thus, in 2000, 1.27 tons of feed units were harvested from 1 ha, and in 2019 – by 48.8% more. The rate of supply of feed unit with digestible protein (from 86.6 to 116.4 g per 1 feed unit) increased by 34.4% during the studied period. Reduction in livestock during the studied period affected the supply of animal feed. If in 2000 only 0.93 tons of feed units were produced per head of cattle, in 2019 – by 15.1% more. At the same time, the level of unprofitable beef production for meat in 2019 in enterprises was 21.3%, and the population of the region was insufficiently supplied with meat and meat products, including offal and raw fat (at the level of 53.6 at the consumption rates of 83 kg per 1 person per year). Conclusions. Non-compliance with the structure of sown areas of the main groups of agricultural crops for the formation of scientifically sound crop rotations has been established. Humidification conditions have a significant influence on the formation of feed crops productivity. The level of unprofitable production of cattle for meat is quite significant, which indicates the need to optimize the feed base. Under the current economic conditions in order to develop livestock production certain measures should be taken to stop the reduction of cattle and to increase animal productivity, including using quality nutritious feeds in the quantities according to feeding rations.
