Plasma profiles and blood glucose values of control and fresh and frozen-thawed camel colostrum and milk groups are presented in Table (1) and Fig (3), respectively.
Plasma profiles
The effects of camel colostrum (fresh and frozen) and camel milk (fresh and frozen) compared to a control group on various biochemical profiles are presented in Table (1). The control group had significantly (P<0.01) lower total protein levels (4.1 g/dl) compared to all other milk and colostrum groups (~4.4-4.6 g/dl). The control, milk and colostrum groups showed varied urea levels. The fresh colostrum and frozen colostrum groups had significantly (P<0.01) lower urea levels (~26 mg/dl) compared to the control, fresh milk and frozen milk groups (~29-31 mg/dl).
The control group had significantly (P<0.01) lower creatinine levels (0.50 mg/dl) compared to all other groups (~0.6-0.7 mg/dl). Glucose levels varied significantly across groups (P<0.001). The frozen milk and colostrum had the highest glucose levels (around 156-159 mg/dl), while the fresh colostrum group had the lowest value (121.5 mg/dl). The control and fresh milk groups had intermediate levels. The fresh and frozen colostrum groups had significantly (P<0.001) lower AST and ALT levels compared to the control, fresh and frozen milk groups. The fresh and frozen colostrum groups had significantly (P<0.05) lower lactate dehydrogenase levels (~542-550 U/l) compared to the other groups (~603-620 U/l). The fresh and frozen colostrum groups had (P<0.001) significantly higher iron levels (~516-537 µmol/L) compared to the control group (349 µmol/L) and the fresh and frozen milk groups (~405-415 µmol/L).
Blood glucose levels
Blood glucose values of low, medium and high body weight of control and fresh camel colostrum groups, respectively, are showed in Fig (3). The results indicated that the low body weight control group had a glucose level of 118.25, while the colostrum group had a glucose level of 98.42 indicating a highly significant difference (P<0.0001). Additionally, the medium body weight control group had a glucose level of 138.90, while the colostrum group had a glucose level of 121.5 indicating a highly significant difference (P<0.0001). Finally, the high body weight control group had a glucose level of 138.20, while the colostrum group had a glucose level of 133.1 indicating none significant difference (P<0.15). The decrease in blood glucose values of low, medium and high body weight mice consuming fresh camel colostrum were 16.76, 12.52 and 3.69% compared to control groups.
Results of the presents experiments are presented in Fig (3) and Table (1) indicating the effects of camel milk and colostrum either fresh or frozen on plasma biochemistry profiles and blood glucose values in mice. Collectively, the obtained results indicated a potential effect of fresh camel colostrum followed by fresh milk in decreasing blood glucose levels versus frozen and control groups. In addition, plasma profiles were improved in fresh and frozen camel milk and colostrum groups compared to control one. These effects could be attributed to the ingredients in camel colostrum and milk (
Mohammed and Alshaibani, 2025). Both camel colostrum and milk contain various biological compounds, some of which can be potentially effect on blood glucose levels and body functions
(Seyiti et al., 2024; Mohammed et al., 2025a). Freezing and thawing, a common method for preserving food and biological samples can have significant effects on protein structures of camel colostrum and milk. These freezing and thawing procedures of milk and colostrum can range from subtle changes in their immunoglobulins and other bioactive compounds conformation to irreversible denaturation and aggregation, ultimately influencing protein functions and stability (
Wöll et al., 2023). Freezing can lead to the formation of ice crystals, which can disrupt these delicate structures, potentially causing denaturation. Freezing can also affect the stability of milk and colostrum lipids, potentially leading to oxidation or other forms of degradation
(Fasse et al., 2021).
Plasma profiles
The effects of camel colostrum and milk, either fresh or frozen, compared to a control group on various biochemical parameters is presented in Table (1). The camel milk and colostrum seems to have a more significant impact on biochemical parameters
(Khaliq et al., 2024). The camel milk and colostrum increased total protein levels (4.4-4.6 g/dl) if compared to control group (4.1 g/dl) due to camel milk and colostrum protein contents (Fig 3). The fresh and frozen camel colostrum groups had significantly lower urea levels (26.0 and 26.5 mg/dl, respectively) compared to the control, fresh and frozen camel milk groups (29.0-31.0 mg/dl), which are generally indicative of better kidney function. The control group had significantly lower creatinine levels (0.50 mg/dl) compared to camel milk and colostrum supplemented groups (0.6-0.7 mg/dl). The increase could be related to increased protein intake in consumed colostrum and milk if compared to control one. The frozen milk and colostrum groups had the highest glucose levels (155.9 and 158.6 mg/dl, respectively), while the fresh colostrum group had the lowest (121.5 mg/dl). The control and fresh milk groups had intermediate levels. This suggests that fresh colostrum have the strongest hypoglycemic effect compared to other groups (
Alshaibani and Mohammed, 2025). Iron levels were significantly higher in the fresh and frozen colostrum colostrum compared to the control and milk groups might be attributed to higher iron contents in camel colostrum (
El-Hatmi et al., 2023). Both AST and ALT were significantly lower in the fresh colostrum and frozen groups compared to other groups. Fresh camel colostrum appears to have beneficial effects on glucose metabolism (lower glucose), liver function (lower AST and ALT) and potentially kidney function (lower urea)
(Khaliq et al., 2024). Camel colostrum is a complex mixture of proteins, immunoglobulins, growth factors and other bioactive compounds. Fully understanding the individual and synergistic effects of these components requires extensive research. The role of the specific active ingredients in camel colostrum can be studied in further studies.
Blood glucose levels
The control group exhibits a relatively stable blood glucose level throughout the experimental period, with a slight increase towards the end. This suggests that without any milk and colostrum supplementation, blood glucose remains consistent with minor fluctuations. The fresh camel colostrum supplementation indicates the strongest hypoglycemic effect followed by fresh camel milk versus the strongest hyperglycemic effect of frozen colostrum and milk, respectively, if compared to control one. The hypoglycemic effect of camel milk has been confirmed in several studies (
García-García et al., 2020;
Mohammadabadi and Jain, 2024;
Mbye et al., 2025) whereas the hypoglycemic effect of camel colostrum has been not explored to the best of our knowledge earlier. Camel milk is suggested to be a suitable hypoglycemic factor in experimental animals and diabetic people (
García-García et al., 2020;
AlKurd et al., 2022; Mohammadabadi and Jain, 2024). Consuming camel milk lowers blood glucose value and reduces the amount of insulin required for treatment by 30-35% for patients with type I diabetes
(Mirmiran et al., 2017; García-García et al., 2020;
Mohammadabadi and Jain, 2024). It has been assumed that camel milk contains insulin-like proteins that enhance health of diabetic patients
(Anwar et al., 2022). With frozen procedures, such insulin-like proteins in camel colostrum and milk might be denatured and aggregated. In addition, the SNF, fat, proteins and lactose contents of camel colostrum and milk could be attributed to hyperglycemic effect of frozen colostrum and milk if compared to control group.
A comparison of blood glucose levels (mg/dl) between control mice groups and treated mice groups of low, medium and high body weights receiving fresh colostrum in shown in Fig (3). The most striking observation is lowering blood glucose levels in groups receiving fresh colostrum if compared to control groups within each body weight category. The difference in blood glucose values between the control and colostrum receiving groups is substantial in the low body weight category. This suggests that individuals with lower body weights might experience a more pronounced glucose lowering (16.91% P<0.001) benefit from colostrum supplementation compared to medium (12.52% P<0.01) and high (3.69% P<0.09) body weight categories. The result provides compelling evidence that fresh camel colostrum supplementation suggests a possible interaction between body weight and the effectiveness of fresh camel colostrum on glucose regulation, with the effect potentially being more pronounced in individuals with lower body weights. Excess body weight is a major risk factor for insulin resistance
(Buscemi et al., 2024). In addition, fat cells, especially those in the abdomen, release hormones and other substances that can interfere with insulin’s action
(Dilworth et al., 2021).
