Three treatments were tested with four replications at RCBD, namely cassava monoculture, corn twice under cassava intercropping, and corn with corn monoculture where the second corn was planted 5 days after harvested. Planting distance of cassava in monoculture was 100x100 cm, and in intercropping was 200x50 cm, by which corn was planted in 50x30 cm, 1 seed per hole. All plots received dairy cattle manure 5 t haE-1. Fertilizer applied for cassava was Urea 100 kg haE-1, Ponska 200 kg haE-1 and KCl 100 kg haE-1 split into two applications two weeks after cassava planting, then when first of corn was harvested. Corn fertilization was Ponska 150 kg haE-1 + Urea 100 kg haE-1 every 3 months and split into two applications: 1 week and 4 weeks after corn was planted. Cassava and twice corn fertilization was Urea 300 kg haE-1 + Phonska 400 kg haE-1 + KCl 100 kg haE-1. Results showed that cassava monoculture can be improved by inserting of twice corn in between rows. Under sole cropping cassava, the B/C ratio was the highest 1.61, however with incorporating twice of corn the B/C ratio was 1.58. Intercropping cassava and twice of corn resulted in the Land Equivalent Ratio 2.146. By intercropping cassava with corn twice at the end of dry season, there was an opportunity to find corn biomass for dairy cattle. Under intercropping, cassava was able to produce 21.5 t haE-1 of fresh roots, while first and second of corn produced fresh biomass of 34 t haE-1 and 28 t haE-1 respectively.

Feeding young animals is a very important stage during their growing-up period, but in order to provide them with essential nutrients, they are fed with liquid feeds, whole milk substitute in particular (WMS). The technique for reconstituting WMS consists of dissolving it in water followed by mixing, but it is significant to follow the cooking recipe strictly, so it is necessary to develop a system with a feeding (dosing) device that will make it possible to solve this problem. Theoretical and experimental studies of the feeding device have been conducted in order to optimize the technological process of mixing liquid feed. Theoretically, the quality of determining the mixture during dosing was established for the purpose of further research. The influence of the design and technological parameters of the feeding device was experimentally studied, and its efficiency was evaluated. It was found that as the inclination angle α increases from 67,50 to 700, the rotation speed n being from 850 to 1500 minE−1, the maximum probability of staying in the tolerance field ΔP=96% is reached, and feed discharge Q ranges from 540 to 660 kg hE−1. The research makes it possible to develop a feeding device at the design stage, meeting the requirements of the recipe, having high discharge rates and the lowest energy consumption.

2022
Cherevko, Iryna
This study aimed to identify the most characteristic trends in the area of fodder production and the use of fodder as factors in the development of animal husbandry in Ukraine under conditions of war as the modern challenge for these industries. Russian military aggression is a powerful challenge for the economy of Ukraine, including its fodder production, as well as other countries of the world, reflecting on the aggravation of global problems of food shortages and food security. The effect of the mentioned challenge in Ukraine is superimposed on the identified negative trends and situation, which were formed before the beginning of 2022. Calculations based on them show that the occupation of large areas of Ukraine by Russian aggressors and hostilities caused a significant decrease in the production of livestock products due to a 13–17% decrease in the number of animals. Accordingly, consumption of fodder at the expense of these regions decreased by 16%. However, the situation is very dynamic as the war continues. Given the limitations of state support for the industry, until the end of the war the main efforts to improve fodder production in Ukraine should objectively be related to the maximum optimization of the structure of fodder rations by increasing the share of less energy-intensive forages. Every challenge creates new opportunities, therefore the post-war development of fodder production and use in Ukraine will become highly innovative.
