The present study was conducted to investigate the effects of Purslane herb, mushroom residual and Sunflower seed hulls on body weight, days to lay cessation, age to reach target weight and return to production in 252 Hy-Line W-36 of laying hens at 78 weeks of ages. Experiment was arranged in a completely randomized design (CRD) including 7 treatments, 6 replicates cages and 6 birds in each. Treatments including: feed removal (control), basal diet (diets were formulated with corn and soy bean meal in according Hy-Line international recommendation 2014) + 30% sunflower seed hulls + 2% Purslane herb powder, basal diet + 2% Purslane herb powder, basal diet + 30% sunflower seed hulls + 2% white button mushroom residual, basal diet + 2% white button mushroom residual, basal diet + 30% sunflower seed hulls and basal diet. The results have indicated target weight (30% weight loss) was achieved by treatment feed removal faster than other treatments (P<0.0001). Stop egg production was shown by feed removal hens (P<0.0001). There were no significant effect on initial weight, body loss weight in day 15 by treatment. Layers submitted to feed removal during the induced-molting period presented higher loss weight in day 6 compared treatments 2,3,4 and 5 (p< 0.05). The early day returned to egg-laying have shown by treatments 4 and 5 (P<0.0001). The has been reported that Portulaca oleracea have effects on potential anti-obesity and reduced body weight gain [1]. Portulaca Oleracea has proved to possess anti-ovulatory and estrogenic activity [2], Therefore it could be used for molting. White button mushroom by reducing the activity of aromatase could suppress estrogen product [3]. It was concluded that the supplementation with white button mushroom residual was molting method alternative to feed fasting were effective to induce molting in layer hens.
