CARACTERISATION PHYSICO-CHIMIQUE DU COLOSTRUM CAMELIN (Camelus dromedarius)

Abstract

The studies have proved that the camel colostrum has a particular interest for both the camel calf and nomads and southern populations because it satisfies their requirements given its high content of basic nutrients (proteins, lipids, and lactose) as well as vitamin C. It is also characterized by its powerful natural protective system (lactoperoxidase, lactoferrin, immunoglobulins and proteose-peptones3), thus distinguishing it from bovine colostrum. The purpose of this work is the characterization of this bio-product by performing physicochemical analyzes on a sample taken in Zone of Taïbat Ouargla and compares them with those of a sample of bovine colostrum. The results have revealed that the pH of camel colostrum is 6.50 ± 0.13, acidity Dornic is 14.5 ± 0.01, so less acid that bovine colostrum, the density is higher than that of bovine colostrum of the order of 1.049 ± 0.001, the total dry matter content is slightly reduced compared to that of bovine colostrum estimated to 120 ± 0.032 g / l, the quantity of lipids is much lower than that of bovine colostrum and estimated to 40 ± 0.00 g/l, and the ashes of the order of 6.5 ± 0.0057 g / l. This colostrum is essentially characterized by very high rates of vitamin C and proteins. The value of vitamin C is more than 2,5 that found in bovine colostrum (the average value is estimated to be 84.48 ± 8.01 mg / l) and the value of protein is evaluated in the order of 55.5 ± 3.5 g / l.
