Camel milk is recognized by nomads for its therapeutic effect to treat several diseases especially diabetes. This study was conducted to evaluate the effect of raw, pasteurized and boiled camel milk on Alloxan- induced diabetic dogs. Firstly, three groups of dogs were used: group 1 and group 2 composed each of 4 diabetic dogs and receiving respectively 250 ml of raw camel milk/ dog/ day or 250 ml of raw cow milk/ dog/ day. Group 3 consisted of 4 healthy dogs getting raw camel milk were used as control. Secondly, we tested the effect of heat treatment on the anti-diabetic property of camel milk. Two other groups composed of 4 diabetics dogs each and treated with 250 ml of pasteurized camel milk/ dog/ day (group 4) or with 250 ml of boiled camel milk/ dog/ day (group 5). By the end of milk treatment, group1 showed a significant decrease in blood glucose (from 10.16 ± 1.16 to 5.22 ± 1.06 mmol/l), in cholesterol (6.94 ± 0.06 to 5.04 ± 0.8 mmol/l) and in total proteins levels (from 75.31 ± 4.68 to 65.44 ± 0.76 g/l). A same result was revealAed in animals getting pasteurized camel milk: blood glucose, in cholesterol and total protein concentrations. After 3 weeks of treatment with pasteurized milk, all these parameters didn’t show any significant differences when compared with group 1 (treated with raw camel milk). Whereas, the animals receiving boiled camel milk (group 5) demonstrated high blood glucose (10.5 ± 0.52 mmol/l), total proteins (72.03 ± 6.49 g/l) and cholesterol levels (7.02 ± 0.44 mmol/l). The investigation during this research was not only the effectiveness of “raw or pasteurized” camel milk to treat diabetic dogs but especially the curative effect of this product shown after stopping to drink milk. However this therapeutic effect was disappearing using boiled camel milk to treat diabetic dogs.
