The Effect of using Nano-Selenium and Vitamin D3 on some Blood Parameters in Male Awassi Lambs

The research was carried out in the Animal Production Department of the College of Agriculture at Tikrit University in Iraq. The goal of this study was to examine the impact of administering nano-selenium and vitamin D3 to Awassi sheep on a variety of biochemical parameters of blood. Sixteen Awassi lambs were employed in the study; their ages ranged from (4-5) months, and their average weight was (19.56 0.17 kg). These lambs were randomly split into four groups (4 animals per group), and the investigation spanned two time periods (45 and 90 days). The first group (control) received 10 ml of distilled water (per animal), while the second group (treatment) was dosed with 0.5 mg of selenium nanoparticles/kg of feed and the third group (treatment) was dosed with 5.5 international units of vitamin D3/kg of body weight. Fourth, the results of this investigation showed that the levels of total cholesterol, triglycerides, and low lipoproteins all decreased significantly (P≤0.05) after a combination dose of the nano-element selenium and vitamin D3 (0.5 mg/kg feed + 5.5 international units/kg body weight). High-density lipoproteins were significantly increased (P≤0.05) in the second treatment compared to the control treatment, but low-density and very low-density lipoproteins were decreased. Serum creatinine levels were found to be significantly lower after the second and fourth treatments compared to the first (control) and third treatments (P≤0.05), whereas blood urea levels and AST and ALT enzyme levels were not statistically different between the treatments.
