During the peripa.turient period, da.ry cows exhibit nega.ive energy ba.a.ce due to limited a.petite a.d increa.ed energy requirements for la.togenesis. The delica.e equilibrium between energy a.a.la.ility a.d expenditure puts cows in a.sta.e of meta.olic stress cha.a.terized by excessive lipolysis in white a.ipose tissues(a.), increa.ed production of rea.tive oxygen species, a.d immune cell dysfunction.

In this work the influence of the density of the molten meta. on the emergence of the ra.ning phenomenon in the horizonta. centrifuga. ca.ting process is numerica.ly studied. Tra.sient 2D numerica. simula.ions were ca.ried out using Computa.iona. Fluid Dyna.ics softwa.e. Three molten meta.s with different density, na.ely a.uminum, iron a.d lea., a.d three a.gula. frequencies, na.ely 50, 66 a.d 77 ra./s were considered. It is found tha. the density of the molten meta. significa.tly a.fects the emergence, tra.sient or perma.ent, of the ra.n phenomenon. However, the ma.nitude a.d dura.ion of the ra.n phenomenon depend on the a.gula. frequency of the rota.ing mold. Likewise, since gra.ita.iona. forces a.fect the meta. a.cording to its density, the va.ue of the critica. rota.ion speed of the mold is a.so a.fected.
