Balancing parent flock concentrate mixture accordance with the norms and restrictions

Abstract

The paper presents the needs of pheasant flock and the possibility of designing a mixture with substitutions feed of animal origin or products of soybean processing. Basis of concrete examples, three types of concentrate mixtures, it can be seen that the preparation of concentrate mixtures for pheasants hens possible without the use of animal feedstuffs, while reducing the share of products of soybean processing, using synthetic amino acids. Thanks to this, a lower price and concentrate mixtures. At the same time, it is possible to fulfill the requirements in accordance with the standards and restrictions for certain nutrients because of the presence of some toxic matters.

U radu su izložene potrebe matičnog jata fazana i mogućnost balansiranja smeša uz supstituciju hraniva animalnog porekla ili proizvoda prerade soje. Na osnovu konkretnih primera, odnosno tri vrste smeša koncentrata, vidi se da je pripremanje smeša koncentrata za fazanke nosilje moguće bez upotrebe hraniva animalnog porekla, uz smanjenje udela proizvoda prerade soje, korišćenjem sintetičkih aminokiselina. Zahvaljujući tome, postiže se i niža cena smeša koncentrata. Istovremeno, na taj način moguće je ispuniti zahteve u skladu sa normativima, kao i ograničenja za pojedina hraniva zbog prisustva nekih antinutritivnih materija.
