| Abstract | ||
| This study was conducted at the poultry research station of the Agricultural Research Department, Ministry of Agriculture from June 27 to October 17, 2024. It investigated the effect of using different proportions of a local shiitake mushroom waste powder in laying hens diets, with or without adding probiotics, on some chemical traits and the oxidation status of their eggs. A total of 135 ISA Brown laying hens were distributed into nine treatments, each containing three replicates, with 5 birds per replicate. The treatments were as follows: control (T1) comprising a basic diet without the shiitake mushroom waste powder, T2, T3, T4, and T5 with the powder at 2, 4, 6 and 8%, respectively, and T6, T7, T8, and T9 with the same powder rates, respectively, together with probiotics. The results indicated no differences in cholesterol concentration between the treatments using the waste powder and the control treatment T1, except for a highly significant (P≤0.01) decrease in the egg yolk cholesterol for treatment T4. A similar increase was also observed in the concentration of linoleic, palmitic, and oleic fatty acids for most treatments using the mushroom growth waste powder. However, a highly significant (P≤0.01) decrease was observed in the values for malondialdehyde (MDA), peroxide (PV), and free fatty acids (FFA) of egg yolk stored for 0, 2, and 3 weeks for most treatments with the local shiitake mushroom growth waste powder, compared to the T1 control treatment | ||
