The use of feedstuffs of animal origin in connection with the new legislative and possibility for their substitution

Abstract

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. .
