In order to evaluate the effects of dietary probiotics, yeast, vitamin E and vitamin C supplementation on performance, serum and yolk cholesterol and immune response of heat stressed laying hens, a trial was conducted with sixty white layer hens of Hy-Line variety. Experiment was conducted by using completely randomized design with 5 treatments, 3 replicates and 4 hens in each replicate. The treatments involved: control, basal diet plus 50 mg multi strains probiotic, basal diet plus 1 g yeast of Saccharomyces cerevisiae, basal diet plus 200 mg vitamin C and basal diet plus 200 mg vitamin E per Kg of diet. Results indicated no significant difference in hen performance, egg quality (shell thickness, shell resistance, shell percent and haugh unit) and serum and yolk cholesterol concentrations. Yolk percent was increased significantly and the highest yolk percent was observed in vitamin E treatment. Immune response of laying hens with multi strains probiotic and yeast supplementation was greater than others. However, dietary vitamin E and C supplementation increased immune response, but differences were not significant compare with other groups.

- Effects of dietary probiotic (Bacillus subtilis) supplementation on productive performance, immune response and egg quality characteristics in laying hens under high ambient temperature (2018, background): “Laying hens received a diet containing multi strains of probiotics exhibited a higher antibody production against SRBC compared with non-treated hens during high environmental temperature (Asli et al. 2007).”
- Effect of vitamin E in heat-stressed poultry (2011, background): “Asli et al. (2007) showed that 200 mg of vitamin E in the basal diet improved yolk percentage in laying hens exposed to heat stress (33°C).”
- Effects of dietary yeast autolysate (Saccharomyces cerevisiae) and black cumin seed (Nigella sativa L.) on performance, egg traits, some blood characteristics and antibody production of laying hens (2012, background): “Some researchers (Abubakar et al., 2007; Mohiti-Asli et al., 2007; Yalçın et al., 2010) also found that yeast and yeast autolysate supplementation had no effect on body weight and feed intake of hens.”
