During lactation the body reserves of nutrients, electrolytes and minerals are lost in milk leading to depletion of reserves.

Objective The objective of the study was to report whether lactations alter the serum biochemical metabolites, electrolytes and minerals profile of one-humped lactating camels or not. Materials and Methods The study involved 25 healthy, one-humped lactating camels (Camelus dromidarious) selected randomly from the desert area of Bhakkar (Punjab, Pakistan). Camels were divided into five groups (each having five camels) on the basis of lactations. The study involved camels in first, second, third, fourth and fifth lactations. Ten milliliter blood was drawn from jugular vein using sterilized needles and plane syringes. Blood samples were allowed to clot at room temperature and centrifuged at 3,000 rpm for 15 minutes. Serum was collected and stored at -20ºC till analysis. Serum biochemical metabolites and hepatic enzymes were evaluated spectrophotometrically using commercial kits and serum thyroid hormones were determined using commercial ELISA kits. Serum electrolytes and minerals were determined using flame photometery and atomic absorption spectrophotometery, respectively, after wet digestion of serum. Data was analyzed using one way analysis of variance by SPSS and significance was set at P < 0.05. Results Serum concentration of glucose, total proteins, albumin and globulins, triglycerides, HDL-cholesterol, LDL-cholesterol, uric acid, and thyroid enzymes did not differ among all the five lactation stages. Serum cholesterol concentration was significantly higher during second lactation compared with the first, third, forth and fifth lactations. Serum aspartate aminotransferase concentration was significantly higher during first lactation compared with the fourth lactation. Serum alanine aminotransferase concentration was significantly higher during fifth lactation compared with the first lactation. Serum concentration of minerals like calcium, magnesium, iron, manganese and selenium did not differ during any lactation. Similarly, serum electrolytes including sodium and potassium also did not differ between subsequent lactations. Conclusion Lactations have not much pronounced effects on the serum biochemical metabolites, electrolytes and minerals profile of one-humped lactating camels.

Background
Lactation is characterized by change in metabolic demands of body that induces stress in lactating animals. During lactation the body reserves of nutrients, electrolytes and minerals are lost in milk leading to depletion of reserves. Therefore, lactating animals may suffer from deficiency of nutrients, electrolytes and minerals.
Objective
The objective of the study was to report whether lactations alter the serum biochemical metabolites, electrolytes and minerals profile of one-humped lactating camels or not.
Materials and Methods
The study involved 25 healthy, one-humped lactating camels (Camelus dromidarious) selected randomly from the desert area of Bhakkar (Punjab, Pakistan). Camels were divided into five groups (each having five camels) on the basis of lactations. The study involved camels in first, second, third, fourth and fifth lactations.
Ten milliliter blood was drawn from jugular vein using sterilized needles and plane syringes. Blood samples were allowed to clot at room temperature and centrifuged at 3,000 rpm for 15 minutes. Serum was collected and stored at -20ºC till analysis. Serum biochemical metabolites and hepatic enzymes were evaluated spectrophotometrically using commercial kits and serum thyroid hormones were determined using commercial ELISA kits. Serum electrolytes and minerals were determined using flame photometery and atomic absorption spectrophotometery, respectively, after wet digestion of serum. Data was analyzed using one way analysis of variance by SPSS and significance was set at P < 0.05.
Results
Serum concentration of glucose, total proteins, albumin and globulins, triglycerides, HDL-cholesterol, LDL-cholesterol, uric acid, and thyroid enzymes did not differ among all the five lactation stages. Serum cholesterol concentration was significantly higher during second lactation compared with the first, third, forth and fifth lactations. Serum aspartate aminotransferase concentration was significantly higher during first lactation compared with the fourth lactation. Serum alanine aminotransferase concentration was significantly higher during fifth lactation compared with the first lactation. Serum concentration of minerals like calcium, magnesium, iron, manganese and selenium did not differ during any lactation. Similarly, serum electrolytes including sodium and potassium also did not differ between subsequent lactations.
Conclusion
Lactations have not much pronounced effects on the serum biochemical metabolites, electrolytes and minerals profile of one-humped lactating camels.
