This trial aimed to find out the effect of camel milk and its derivatives on triglycerides and cholesterol levels in Alloxan-Induced diabetic rabbits. Diabetes was induced by intravenous injection of Alloxan solution. The diabetic rabbits were treated with fresh and fermented camel milk and colostrums for 60 days. The results demonstrated that triglycerides and cholesterol levels were reduced throughout the experimental period when using camel milk and its derivatives and the levels were kept within the accepted ranges.
The diet rich in saturated fats, smoking, lifestyle, and increased visceral fat is raising LDL (low-density lipoprotein) cholesterol levels . Significant higher levels of triglycerides in Sudanese diabetic patients may be due to overproduction of VLDL (very- low-density lipoprotein) lead to increase plasma levels of triglyceride which, via an exchange process mediated by Cholesterol Ester Transfer Protein (CETP), result in lower levels of high-density lipoprotein HDL-cholesterol, which results in faulty glucose utilization causes hyperglycemia and mobilization of fatty acids from adipose tissue. In diabetes blood, glucose is not utilized by tissue resulting in hyperglycemia. The fatty acids from adipose tissue are mobilized for energy purposes and excess fatty acid is accumulated in the liver, which is converted to triglyceride .
Elevated levels of cholesterol in the blood are regarded as a major risk factor for heart disease. It has been demonstrated that the administration of fermented camel milk has a hypocholesterolemic effect in rats . The hypo cholesterol mechanism of camel milk is still unclear, but different hypotheses were discussed, including the interaction between bioactive peptides from camel milk and cholesterol levels are derived, which lead to cholesterol-lowering  and the presence of orotic acid in camel milk (arises as an intermediate in the metabolism of the nucleic acids), which is considered responsible for the lowering of cholesterol levels in rats and in humans [5,6]. The data concerning the management of high Triglyceride (TG) levels and low HDL cholesterol levels remains inconclusive . So this trial aimed to find out the effect of camel milk and its derivatives on Triglycerides and Cholesterol levels in Alloxan-Induced diabetic rabbits.
The material used includes a thermostatic water bath at 37°C and analyzer, blood samples.
Experimental design: Thirty clinically normal one-year-old rabbits of both sexes on an average weight of 3-3.5Kg were provided; Completely Randomized Design (CRD) was used where they were divided into six groups each with five rabbits. The animals were fed with green carrot (Caucus Carrot) and tap water and provided with air-conditioned quarters at 24°C under standard husbandry conditions in the University of Kordofan exponential farm for 60 days during January 2021.
Alloxan inducing diabetes: Diabetes in the rabbits was induced by intravenous injection of Alloxan . A fresh solution of Alloxan was prepared and the rabbits in five groups were administered 80mg/Kg body weight of the solution while one group was left untreated with Alloxan as a control group. After a week of Alloxan injection, diabetes was confirmed through the measurement of blood glucose levels from heart blood using a glucometer (Prestige). Rabbits with blood glucose concentrations ≥ 8.0mm. ol/L were selected for the experiment.
Treatment groups: The treated groups were designated as follow:
Cholesterol in the blood of rabbits was measured every 15 days for a total period of 60 days.
Serum Total Cholesterol (TC) was determined according to  as follow:
Serum triglycerides (TAG) were determined according to . Serum or plasma was collected by standard procedures where Triglycerides in serum or plasma were stable for 5 days at 2-8°C. Heparin, EDTA, oxalate, and fluoride were used as anticoagulants. Test steps were as follow:
The Triglycerides concentration in the sample was calculated using the following general formula:
Table 1 and Figure 1; demonstrated that Group 1 (nondiabetic - none supplemented) showed Triglycerides (TAG) levels which fluctuated between 142.6 to 145.4mg/dl throughout the period of the experiment from 0-60 days. In the case of Group 2 (diabetic-non supplemented) level of Triglycerides was increased from 239.4mg/dl at 0 days to reach the level of 338mg/dl at 60 days as the highest value as compared with other groups. From 0-60 days, in Group 3 (diabetic-treated with colostrums) Triglycerides decreased from 229.5mg/dl to 165.0mg/dl, in Group 4 (diabetic-treated with milk) decreased from 227.3mg/dl to 173.0mg/dl, in Group 5 (diabetic-treated with gars) from 208.1mg/dl to 179.8 mg/dl and in Group 6 (diabetic-treated with Insulin16 mg for each kg body weight daily for 8 weeks) decreased from 224.4mg/dl to 164.7mg/dl. It was demonstrated that there were no significant differences in Triglycerides levels between Group 1 (control), Group 3, Group 4, Group 5, and Group 6 at 0.05 level of significance, and the values were found to be within the normal level range (140-176mg/dl), the highest level of Triglycerides level at 60 days was recorded by Group 2 (diabetic-non supplemented). It is concluded that treatments of diabetic rabbits with colostrums, camel milk, gars, and insulin resulted in decreasing Triglycerides levels and kept within the normal level.
In Table 2 and Figure 2; Group 1 (nondiabetic - none supplemented) demonstrated Cholesterol (TC) levels which fluctuated between 126.0 to 129.0 mg/dl throughout the experimental period from 0-60 days and were found to be within the normal range (100-200mg/dl). In the case of Group 2 (diabetic-non supplemented) level of total Cholesterol was increased from 270.4 mg/dl at 0 days to reach the maximum level of 306.7 mg/dl at 60 days as the highest value as compared with other groups and it was above the normal limits. From 0 day to 60 days, in Group 3 (diabetic-treated with colostrums) total Cholesterol level decreased from 265.8mg/dl to 187.9mg/dl, in Group 4 (diabetic-treated with milk) decreased from 243.8mg/dl to 190.5mg/dl, in Group 5 (diabetic-treated with gars) from 241.4mg/dl to 200.0 mg/dl and in Group 6 (diabetic-treated with Insulin16 mg/kg body weight daily for 8 weeks) decreased from 238.5mg/dl to 161.4mg/dl. It was demonstrated that there were no significant differences in total Cholesterol levels between Group 3, Group 4, Group 5, and Group 6 at 0.05 level of significance, and the values were found to be within the normal range (100-200mg/dl), the highest level of total Cholesterol level at 60 days was recorded by Group 2 (diabetic-non supplemented). It is deduced that treatments of diabetic rabbits with colostrums, camel milk, gars, and insulin resulted in decreasing total Cholesterol levels, kept within the normal levels, and maintained at desirable levels (less than 200). The obtained results were found to be in the line with [5,6] findings.
Diabetic rabbits treated with fresh and fermented camel milk and colostrums reduced the Triglycerides levels to be retained within the required level. Treatments of diabetic rabbits with fresh and fermented camel milk and colostrums decreased the total cholesterol levels to be kept within the normal range and maintained at a desirable level.
