Physico-chemical and sensorial properties of milk of the Sindi cows supplemented at pasture

Abstract

It was analyzed the effect of supplementation (0,00; 0,35; 0,70, 1,05 e 1,40%) on increasing levels in relation to their alive weight on the Physico-chemical and sensorial properties of cow milk. Five Sindi lactating cows were used (355+35,5kg), allocated as one Latin squares (5x5) into five treatments and five periods of 14 days (11 of adaptation of the animals to the diets and 3 of milk collection). The milk sampling for performing the chemical analysis and sensory evaluation was done in the three last days of each trial period (13th, 14th and 15th days). The sensory evaluation of milk was performed in quantitative descriptive analysis (QDA). No effect of the diets was observed on milk chemical composition, which showed mean values of density (1.033), acidity (18,16°D), fat (3,48 %), lactose (5,17 %), total dry extract (12,59%), protein (3,28%). The results of ADQ show that the supllementation at pasture in Sindi cows did not cause sensorial perceptible changes in the milk. Increasing levels of supplementation at pasture of the Sindi cows milk did not change the composition and sensorial characteristics of milk.
