Abstract
The purpose of this paper is to make an assessment on the main parameters that characterize the quality and quantity of milk production and correlations between them. To achieve this goal, we studied a total of 497 adult goats belonging to three populations in north-eastern Romania, coverage of the population belonging to native goats. Working methods used are specific to this kind of research, using the A4 method, apparatus Ecomilk and Milko-Skane, Pirson correlation and Fisher test. The results of this study highlight the fact that the amount of milk recorded goats studied had an average of 184.01 kg, no significant differences between the populations studied (P>0.05). Physical and sensory analysis indicated that goat milk is presented as a yellowish-white liquid with a characteristic taste and smell, an average density of 1.034, pH 6.45 and freezing point at -0.58C. Data on gross chemical composition of goat milk shows an average concentration of fat and lactose little more than 4% and an average of 3.07% protein, no statistically significant differences has been found between the populations studied. The close correlations with the quantity of milk are assigned characters: the amount of lactose (+0.996), protein (+0.957) and amount of fat (+0.927). Local goats populations is characterized by a relatively low milk production in comparison with specialized breeds.
