The production and use of feedstuffs of animal origin in our country and the world are explained in the paper. The use of all feedstuffs of animal origin, with the exception of milk products, is forbidden in ruminant feeding due to danger of distribution of lethal disease Bovine spongiform encephalopathy-BSE, and their use is limited in nonruminant nutrition (pigs and poultry). Instead of those feedstuffs various substitutions based on combined plant feeds and synthetic amino acids, or commercial fish meal substitutes are gaining popularity in nonruminant nutrition. In ruminant nutrition there was never widely accepted practice to use animal feedstuffs in our country, aside from dried skimmed milk in milk replacer formulas for calves, lambs and kids. As an alternative, there is a practice to include some urea in concentrate mixtures or when silage is made, which is increasing the crude protein content and significantly decrease costs of feeding. . ; U radu je dat pregled proizvodnje i upotrebe hraniva animalnog porekla u našoj zemlji i svetu. Korišćenje hraniva animalnog porekla, sa izuzetkom mleka i proizvoda prerade mleka, zabranjeno je u ishrani preživara zbog opasnosti prenošenja i širenja bolesti Bovine spongiform encephalopathy-BSE (kravlje ludilo), a ograničeno je u ishrani nepreživara (svinja i živine). U ishrani nepreživara sve se češće koriste adekvatne zamene, na bazi kombinacije kvalitetnih hraniva biljnog porekla i sintetičkih aminokiselina, ili komercijalnih zamena za riblje brašno. U ishrani preživara kod nas nikada nije ni postojala praksa upotrebe hraniva animalnog porekla, osim mleka u prahu u zamenama za mleko za telad, jagnjad i jarad. Umesto toga, i danas se praktikuje da se u smeše koncentrata ili pri siliranju kukuruza uključuju odgovarajuće doze uree, čime se povećava količina sirovih proteina, a istovremeno značajno pojeftinjuje ishrana. .
This research monograph consists of 17 papers under the framework of contemporary economic and business issues which we can structure into several main research fields. These fields relate to the regulation of economic and business activities, especially in the context of digitalization processes, fiscal and monetary issues, dealing with the impact of digitalization and COVID19 pandemics on traditional academic and business debates, as well as on innovation processes in both government and the corporate sector. We can borrow the phrase from one of our papers and confirm that the papers presented show that the innovative market and digital society, as the new global development and technology paradigm of the modern world, together with its capabilities and standards, has changed the character of entrepreneurship and the state/government in terms of their new interactions. Thus, the contributions from the research monograph are made more urgent by the main objective of introspection of the traditional economic and business sectors and activities under the prism of digital transformation. The researchers were particularly interested in the impact of the COVID19 pandemic on the economic and business sectors. Although the conference was held in the midst of the pandemics, researchers were able to present valuable studies showing the extent of the threat posed by COVID 19 to the public health and economic outcomes of EU citizens. Significant pressure was placed on member state spending, particularly in countries with lower fiscal capacity, resulting in a severe temporary deterioration in the fiscal deficit and public debt. It is also noted that the crisis COVID -19 will have an uneven impact on member states and could deepen their divergence. Therefore, new and creative fiscal policies to support investment in digital transformation, green transition and innovation are of utmost importance. This monograph provides some guidance.
