EFFECT OF SUPPLEMENTATION WITH ORGANIC COPPER INTO BASAL DIET ON COPPER TOXICITY, AND PHYSIOLOGICAL RESPONSE OF AWASSI LAMBS
This study was conducted to evaluate tolerance and deficiencies of copper (Cu) of Awassi lambs fed on different levels of organic copper. Twenty-four lambs with age eight months and an average weight of 25.5 ± 3.69 kg were used over a duration of 90 days. The animals were randomly assigne...

| Summary: | This study was conducted to evaluate tolerance and deficiencies of copper (Cu) of Awassi lambs fed on different levels of organic copper. Twenty-four lambs with age eight months and an average weight of 25.5 ± 3.69 kg were used over a duration of 90 days. The animals were randomly assigned to four feeding treatments: OCC (basal diet contained on premix of minerals and vitamin), OCF (basal diet without mineral premix), OCC5 (basal diet with 0.5 g organic copper / kg of feed), and OCC1 (basal diet with 1 g organic copper / kg of feed). Throughout the trial samples were collected to examine the hematological and biochemical characteristics of the blood, as well as the levels of metals in the blood, feed, and fecal samples. The results showed a significant decrease (P<0.01) in platelet, platelet distribution width at day 90 and procalcitonin levels at day 45 in OCC1 compared to control treatment (OCC). During the mid of experiment, the concentration of AST enzyme, copper, and iron (Fe) significantly increased in OCC1 compared to the other treatments. At the end of the experiment ALT enzyme increased significantly in OCF compared to other treatments. There were no significant variations in several blood traits across the treatments over the duration of the study. The study's results suggest that providing Awassi lambs with a diet containing more than 0.5 g/kg of Cu for a duration of 90 days did not lead to Cu toxicity or any negative health consequences |
