E. H. Hamad | Th. T. Mohammed
This study conducted in one of the poultry fields of the Department of Animal Production/College of Agriculture/University of Anbar, for the period from 20/7/2021 to 10/13/2021, in order to know the effect of adding natural zeols to the diet of laying hens during hot weather on some physiological traits. For laying hens and the case of antioxidants. 72 laying hens were used in this experiment, Lohman Brown strain, 43 weeks old, and they were randomly distributed to six treatments and four replicates per treatment (3 hens for each replicate). T2, T3, T4 and T5 by adding 0.25, 0.50, 0.75 and 1.0% sequentially, natural zeolite and T6 to the control treatment. The results showed the superiority of the addition treatments in the physiological characteristics and There was a significant decrease (P≤0.05) in the concentration of creatine and MDA in the treatment T5 during the experiment period. while a significant (P≤0.05) in the concentration of GSH-PX for the two treatments T4 and T5 and a significant increase in the concentration of ALP for T5 appeared. and T1 during the duration of the experiment, as well as the treatment of T3 excelled in the concentration of AST enzyme over the treatments of the experiment.
