EFFECT OF ADDING TWO LEVELS OF ORGANIC SELENIUM AND SELENIUM NANOPARTICLES IN THE DIET ON THE BLOOD BIOCHEMICAL TRAITS AND LIPID PROFILE OF BROILER CHICKENS ROSS 308

Abstract

This experiment was conducted at the poultry farm in the Animal Production Department at the College of Agriculture, Al-Qasim Green University, during the period from 31/1/2018 until 13/ 3 / 2018 the study was aimed to Effect of Adding Two Levels of Organic Selenium and Selenium Nanoparticles in the Diet on the Blood Biochemical Traits and lipid profile of Broiler Chickens Ross 308 using 225 broiler chicks with one day years old. It was randomly divided into five treatments with 45 birds per treatment whereas,. The treatments of the experiment were as follows: First treatment Without any addition, second and third treatment: Organic selenium was added to the feed 0.4, 0.5 mg / kg feed respectively and the fourth and fifth treatment: addition 0.4, 0.5 mg nano-selenium particles / kg feed .The experiment included a study of the following characteristics : total protein, albumin, globulin, ALT , AST , Glutathione peroxidase, cholesterol , Triglycerides , High-density lipoproteins, Low- density lipoproteins and Malondialdehyde .The results dicated The highest level of serum protein concentration (p <0.05) was observed in the serum level of the third, fourth and fifth treatments broilers compared with the control treatment. The fourth and the fifth treatments were significantly improvement (p < 0.05) in the level of concentration of serum globulin compared to the first treatment , the results of the study showed no significant differences between the experimental treatments in enzymatic activity (AST) and (ALT) in the serum, while the fourth and fifth treatments were significantly improvement (p <0.05) in the concentration of Glutathione peroxidase compared to the first, second and third treatments. There was significance decrease (P <0.05) in the concentration of cholesterol and triglycerides, as well as low-density lipoproteins and high levels of high-density lipoproteins in the serum of broiler compared to the first treatment . The second, fourth, and fifth treatments recorded a significant decrease (P <0.05) in the level of Malondialdehyde compared to the first and the third treatments.
