ESTUDO COMPARATIVO DA COMPOSIÇÃO QUÍMICA, ÁCIDOS GRAXOS E COLESTEROL DE LEITES DE BÚFALA E VACA

Abstract

The aim of this work was compare the buffaloes and cow’s milk quality. The samples were from cross buffaloes (Jaffarabadi x Murrah) and cow’s (Frisian x Zebu), collected from 2012 April to June.Was determined milk chemical composition (lactose, fat, protein, total solid and milk solids), physical characteris- tics (pH, density and milk acidity). The data were submitted to variance analyze, using F - test (P<0.05). The buffaloes present more level of the fat, protein, lactose, milk solids than cows. In relations to hipercholester- olemics fatty acids, the buffaloes presented hight level to the C16:0 and Lower levels of c12 and c14 than cows. Higher levels to the vacenic and rumenic acid were observed in buffaloes Milk than cows. In spite of a higher content of saturated fatty acids, the milk of water buffaloes showed lower ratio n6/n3 and lower choles- terol when compared to cow. The milk of buffalo and cow showed adequate nutritionally These results indi- cate the need for the creation of specific legislation for the buffalo milk.
