Hematological and biochemical study of zinc deficiency in sheep in fallujah city Iraq

الملخص EN

The current study was conducted to estimate the Zinc(Zn) levels in serum of (190) Awassi sheep (males) in Fallujah city/ Iraq.

The animals were examined clinically and serum samples were examined by atomic absorption spectrophotometer (AAS) to detect the Zn concentration, the results showed decrease in zinc level in addition to significant (P<0.05) difference between among the control group 0.67±0.42 ppm and affected which include Al-bushegel group0.21±0.42 ppm, Al-falaahat group0.18±0.12 ppm and Al-bualwaan group0.13±0.27 ppm.

Also, RBCs reduced in Al-bushegel group6.88±0.51* 10%/ul, Al-falaahat group7.03 ± 0.26* 10%/ul, and Al-bualwaan group6.37 ± 0.84* 10%/ul, thus Hb declined in Al-bushegel group 7.13±0.22g/dl, Al-falaahat group 7.27±0.32g/dl, and Al-bualwaan group 6.82 ± 0.43g/dl in the whole blood samples.

PCV was also significant (P<0.05) reduced in Al-bushegel group 21.41±0.53%, Al-falaahat group 21.75 ± 0.48%, and Al-bualwaan group 20.21 ± 0.15%.

On the other hand, the results showed an insignificant difference in MCV among Al-bushegel group 31.1±0.12fL, Al-falaahat group 30.9± 0.92fL, and Al-bualwaan group 31.7± 0.35fL, but there's no substantial difference in MCHC between Al-bushegel group 33.1±0.21g/dl, Al falaahat group 33.4±0.54g/dl, and Al-bualwaan group 32.710.40g/dl.

When compared to control 35.70+2.42 (U/L), there was no significant difference in ALT activity in Al-bushegel group 1 31.16 0.19 (U/L), Al-falaahat group 30.60 ± 0.84 (U/L), and Al-bualwaan group 28.221.13 (U/L).

Furthermore, as compared to control 86.20±18.79 (U/L), AST activity was substantially higher in Al-bushegel group 46.38 ± 1.32 (U/L), Al-falaahat group 42.11 ± 0.82 (U/L), and Albualwaan group 39.48± 1.75 (U/L).

In this investigation, serum urea levels were 48.09 0.05, 43.00 ± 0.47 and 51.50 ± 0.89 (mg/dl) in Al-bushegel, Al-falaahat, and Al bualwaan groups respectively, compared to control levels of 22.35±0.11 mg/dl.

In comparison to control 0.71±0.04 (mg/dl), serum creatinine levels increased significantly in Al-bushegel group 1.09 ± 0.01 (mg/dl), Al-falaahat group 1.12±0.06 (mg/dl), and Al-bualwaan group 1.14 0.03 (mg/dl).

The affected animal group's heart and respiration rates were significantly (P<0.05) higher than those of the control group.

In conclusion, it was a considerable difference in Zinc concentrations, haematological, and biochemical characteristics among sheep studied in Fallujah, Iraq.
