Abstract

Beet pulp resulting from sugar production is, thanks to the easily assimilable carbohydrate content, an important source of feed, especially for ruminants and pigs. The efficiency of its utilization can be substantially improved by adding macroelements and microelements. In order to preserve and maintain the nutritional value of the resulting premix, a drying operation is required. In the paper are presented the results of experiments on how the percentage of macroelements (Ca2+, Mg2+, PO43+) and microelements (Fe3+, Zn2+, Co2+, Cu2+, Mn3+) influence the time variation of moisture and the drying rate of the premix at different drying temperatures and the quality of premixes.

Abstract in Romanian, Moldavian, Moldovan

Pulpa de sfecla rezultata de la fabricarea zaharului reprezintă, datorita conţinutului de carbohidrati usor asimilabili, o sursă importantă de furaj, în special pentru animalele rumegatoare si suine. Eficienţa urilizarii acesteia poate fi substanţial îmbunătăţită prin adăugarea de macroelemente şi microelemente. In vederea conservarii si mentinerii valorii nutritive a premixului rezultat este necesara o operaţie de uscare. In lucrare sunt prezentate rezultatele experimentarilor privind modul în care procentul de macroelemente (Ca2+, Mg2+, PO43+) si microelemente (Fe3+, Zn2+, Co2+, Cu2+, Mn3+) influenţează variaţia în timp a umidităţii şi viteza de uscare a premixului la diferite temperaturi de uscare si calitatea premixurilor.
