The study investigated the impact of postbiotics generated from Lactobacillus acidophilus (Lap) and Lactiplantibacillus plantarum (Lpp) on the productive performance, egg quality, and serum biochemical parameters of laying hens. At 40 weeks of age, 126 Lohmann hens were randomly assigned to seven treatments with three replications of six birds each. The basal diet (T1) was administered without supplements (negative control) or supplemented with tetracycline (T2) at 0.02% (positive control). The other five groups: T3, T4 (basal diet supplemented with postbiotics (Lap) 0.35%, and (Lap) 0.70% produced from Lactobacillus acidophilus bacteria respectively); T5, T6 (basal diet supplemented with postbiotics (Lpp) 0.35%, and (Lpp) 0.70% produced from Lactiplantibacillus plantarum bacteria respectively); T7 (basal diet supplemented with postbiotics (0.35% Lap + 0.35% Lpp). Postbiotics and tetracycline (TET) did not affect (P≥0.05) in body weight, feed intake, feed conversion ratio (FCR), egg weight, egg mass, egg quality or serum total protein, albumin and globulin. Egg production and egg number were greater (P≤0.05) in the postbiotics (Lap 0.70%, Lpp 0.70%, and mixture (0.35% Lap + 0.35% Lpp), and TET supplemental group as compared to the control (T1). While cholesterol and triglycerides (except 0.35% Lap, 0.35% Lpp), were decreased significantly (P≤0.05) than T1. Superoxide dismutase and catalase activity (except 0.35% Lap, 0.35% Lpp) improved as compared to T1. The results indicate that the supplementation of postbiotics has a positive effect on laying hens performance and some biochemical parameters.

This study was conducted to investigate the potential of onion and garlic oils and their mixture supplementation under heat stress on the egg production, egg weight, total lipid concentration and antioxidant activity of local quail hens. Sixty birds at 42 weeks' age were evenly divided randomly into 4 treatments: feed in control (T0) free of onion and garlic oil, T1 and T2 were supplemented 0.2% in each onion or garlic oil, T3 was supplemented mixture of (0.1% onion + 0.1% garlic oil) respectively. The birds reared in temperature-controlled room (35-38°C) at afternoon. The results of enzymatically analysis of catalase, superoxide dismutase, Glutathion-Px activity concentrations, egg production percentage, egg weight and egg mass had significantly higher (P≤0.05) in the most treatments of onion and garlic oils and their mixture supplemented diet. While, significantly lower (P≤0.05) in total cholesterol, hydrogen peroxide (H2O2) and Malondialdehyde (MDA) in onion and garlic oils and their mixture supplemented diet compared with control of blood serum, liver tissue and egg yolk of quail hens under heat stress.
