Evaluation of Some Minerals and Biochemical Traits of Awassi Sheep at Mid and Late Pregnancy

Abstract

The target of this experiment to evaluate the serum concentration of some parameters in pregnant Awassi ewes, the studied ewes divided into three groups each group contain six animals , blood collected from jugular vein, the first group (1^st half) blood collected at mid period of pregnancy (day 75 of pregnant), in second group (2^nd half) the blood collected at end period of pregnancy (few hours before birth) and the last group was control , the ewes in this group were not pregnant and blood collected randomly. Serum glucose, cholesterol, triglyceride, total protein, albumin, globulin, urea, creatinine and some minerals, calcium (Ca), sodium (Na) and potassium

(K) and were tested. The results of this study there's non-significant   (p>0.05) change between serum glucose in all three groups. The urea of studied animals serum was elevated significantly (p≤0.05) in (1^st half) group in comparison with other two groups and in (2^nd half) was significant (p≤0.05) elevation as compared to control (non pregnant) group while the serum creatinine in control group was significant (p≤0.05) elevated as compared with the two other groups. The serum cholesterol and triglyceride found there's non- significant (p>0.05) changes of serum cholesterol in all groups of experiments   but there's significant (p≤0.05) elevation of serum triglyceride in (1^st half) than other groups and there's significant (p≤0.05) increase in (2^nd half) group than (control) group. The total serum protein in (1^st half) increased significantly compared to the two other groups but serum albumin in control group was significantly (p≤0.05) reduced when compared with the two other groups while there's significant (p≤0.05) decrease of this parameter in (2^nd half) group than (1^st half) and the serum globulin revealed no significant (p>0.05) change between control group and (1^st half) group and significant (p≤0.05) reduction in (2^nd half) in comparison with the two others groups. Serum of some minerals, the serum sodium (Na) concentration was no significant (p>0.05) change between all groups in experiments, serum potassium (K) was significantly (p≤0.05) decrease in(1^st half) than control and (2^nd half) while the serum calcium (Ca) concentration appeared significant (p≤0.05) increase in (1^st half) and (2^nd half) groups in comparison to the control group while there's non-significant (p>0.05) difference between (1^st half) and (2^{nd v} half) groups.
